With extremely complicated feelings, Jiang Ran finally did not interrupt the conversation.

Even if you want to take a colorful photo...it's just a dream. What if someone happens to be taking a photo of a rainbow?

Jiang Ran and Bian Zhao stepped back a little before continuing the conversation that was already halfway through.

Bian Zhao: "You want to borrow the hovercraft, probably to go to the tiankeng again."

"That's right," Jiang Ran said without hesitation. "When I went to look for Xiao Gu, I saw the entrance to a cave at the bottom of the tiankeng. At this depth, there must be a magnificent spectacle inside."

"I see."

"Then your hover car..."

"I can lend it to you."

"Thank you very much!"

"Don't be so quick to thank me," Bian Zhao raised his head, "I have a condition."

Jiang Ran: "What conditions?"

Bian Zhao: "I want to go with you."

Even though Jiang Ran had thought about various possible reactions from Bian Zhao, he never expected it to be this one.

Wasn't Bian Zhao on vacation on Earth? Why was he following her underground?

While Jiang Ran was thinking, he asked the confusion in his heart.

Bian Zhao raised his head: "Who told you I was here for vacation?"

Jiang Ran asked back: "Then what are you here for?"

Bian Zhao was sitting in a wheelchair. He did not answer immediately. Instead, he took out a drink from the space button and took a sip leisurely.

After pursing his lips, Bian Zhao said, "I'm here to watch a show."

Jiang Ran was silent for a long time, then asked a question from the bottom of his heart: "Do you think my show is good?"

Bian Zhao took the drink back and said, "It's indeed better looking than those people who studied colorful photos."

Jiang Ran: “…”

Well, consider it a compliment to her.

In any case, Jiang Ran wanted to go down to the bottom of the tiankeng and explore the underground cave, and Zhao's hovercraft was indispensable.

She hesitated for a long time, but finally succumbed to reality and agreed to let Bian Zhao take her down with him.

The two of them rode in a hovercraft and descended to the bottom of the tiankeng, which was over a hundred meters deep.

Behind the cave, there is a huge underground cave system hidden.

Jiang Ran looked at the vines climbing at the entrance of the cave and suddenly thought of Fu Bo and the others.

"I haven't seen them in a while," Jiang Ran said. "If Zeng Pei were here now, she'd probably be curious about the composition of the cave and how it formed."

Bian Zhao glanced at her and said, "I just met a few of them not long ago."

Jiang Ran was a little curious: "Where have you seen it before?"

"We saw them on the beach," Bian Zhao said, his voice devoid of emotion. "They were swimming in a race with tropical fish."

Jiang Ran: “…”

This was indeed something Fu Bo would do, so she shouldn't have asked that question.

As expected of Fu Bo and Ren Xiayang, it was really unfair for Zeng Pei to stay with these childish guys.

But if you think about it carefully... Zeng Pei probably won't be wronged. After all, Fu Bo and the others won't have the chance to show any displeasure to Zeng Pei.

Thinking of this, Jiang Ran pulled his thoughts back.

The underground cave is right in front of them, and they are ready to set off.

After reaching the bottom of the tiankeng, Bian Zhao put away the hovercraft and got on the automatic wheelchair. She controlled the wheelchair and moved forward into the cave with Jiang Ran.

However, after just two steps, the ground inside the cave became increasingly difficult to walk on. Bian Zhao was annoyed by the uneven ground covered with gravel of all sizes, which was not conducive to the movement of her wheelchair.

Seeing Bian Zhao's wheelchair bumping and stumbling from time to time, Jiang Ran couldn't help but feel happy.

She clapped her hands and said meaningfully, "This scene is really great!"

The two words "watch a show" were Bian Zhao's original words. Jiang Ran said this deliberately, and the implication was very obvious.

However, Bian Zhao was not angered by her attitude. He just tried his best to continue moving forward on this bumpy road.

Jiang Ran gloated over her misfortune for a long time, and finally tried to persuade her kindly: "You'd better stop struggling and stand up and walk."

Bian Zhao ignored her. Jiang Ran was just about to try to persuade him again, but the next second she saw Bian Zhao release the hovercraft from the space button again.

This purely natural underground cave is different from the common tourist caves. The passage for human movement is relatively narrow. Although there is still some distance from the top of the cave to the ground, the width from left to right is not large.

Bian Zhao controlled the hover car and traveled through this passage which was only about three or four meters wide.

Jiang Ran: “…”

Jiang Ran: "I have to say, your micro-manipulation skills are quite good."

Bian Zhao had been silent until this moment, then he said, "Thank you for the compliment."

Jiang Ran: "...You're welcome."

After walking forward for a distance and getting away from the cave entrance, the light in the cave became dimmer and dimmer, and finally turned into pitch black.

Jiang Ran was of course well prepared for this. She quickly took out a simple homemade helmet from her backpack, and then deftly tied the light to the helmet, illuminating a bright area in front of her, making it easier for her to find the direction and landing point.

After doing all this, Jiang Ran looked at Bian Zhao out of habit.

At this time, Bian Zhao was still riding in the hover car. With the roof as a shield, he didn't have the trouble and necessity of wearing a helmet. However, Bian Zhao had no lighting tools, so his vision would still be affected by the overly dark environment.

Thinking of this, Jiang Ran reached into his bag and took out another spare flashlight.

She held the light forward and said, "Do you want to..."

Before he finished speaking, two bright lights suddenly lit up on the front and rear covers of Bian Zhao's hovercraft, immediately illuminating the cave brightly and clearly.

"What did you want to say just now?" Bian Zhao asked.

"Nothing." Jiang Ran turned off the lights on his helmet while speaking, and then stuffed both lights back into his backpack.

Technology changes our lives...and it can also change the way we explore.

Putting aside the helmet for now, but looking at the bright passage in front of him, Jiang Ran knew that he would definitely not be able to use his flashlight.

This underground cave system was even larger than Jiang Ran had expected. She and Bian Zhao walked along the narrow passage for more than an hour, but there was no sign of a bright future ahead.

The only good thing is that as you go deeper into the cave, the passage becomes a little bigger.

Of course, this had no effect on Jiang Ran, but Bian Zhao was more adept at controlling the hover car, and it was simpler and easier.

"Bang!"

A stone suddenly fell in front of me.

Jiang Ran looked at the cave ceiling above him and found nothing special. It seemed to be just an accident.

However, after a few minutes, she suddenly felt the ground beneath her feet tremble.

The vibration was not strong, just a slight shake, but it was enough to make Jiang Ran extremely alert.

Jiang Ran's expression quickly turned serious. She knocked on Bian Zhao's floating car door and said, "Something might happen here. We need to find a safe place as soon as possible."

"A place that's safe enough?" Bian Zhao asked.

"Yes, I think..."

Before Jiang Ran could finish his words, he saw Bian Zhao control the car to hover about ten centimeters above the ground, and then opened the car door.

"Come on up," Bian Zhao said, "My hovercraft has three layers of protection. It can even withstand cosmic rays and photon bullets. There's no safer place than this."

Jiang Ran was not pretentious. She didn't hesitate for a moment and got into the hovercraft directly.

Not long after, Jiang Ran's premonition came true.

The ground in the cave began to tremble more and more violently. Although the two of them could not feel the amplitude of the tremors because the hovercraft was suspended in the air, the rocks and gravel that fell from the top of the cave due to the shaking of the ground kept reminding them -

It's very dangerous at this moment.

The only thing to be thankful for is that Bian Zhao is very skilled in operating the hover car.

Although dangerous rubble often falls from the top of the cave, sometimes even just a few centimeters away from the hovercar, Bian Zhao always manages to dodge it in extremely dangerous situations.

Later, something fortunate happened.

The ground shook for only a few minutes before returning to calm, and the cave did not collapse due to this shaking.

In other words, Jiang Ran and Bian Zhao are both safe.

After the earth's shaking stopped, Jiang Ran did not get out of the hovercraft immediately, but waited for a few minutes to confirm the situation.

Jiang Ran finally breathed a sigh of relief when he finally confirmed that they were all completely safe.

Although Jiang Ran survived the disaster, his nervousness didn't last long and he soon calmed down.

At this point, she began to think about something else: "Didn't you say the hovercraft has three layers of protection, so it won't be damaged even if it encounters cosmic rays and photon bullets? Why is it trying so hard to avoid those rocks and rubble?"

Bian Zhao's face was gloomy: "Although it won't break, it will be dirty."

Jiang Ran: “…”

It turns out that Bian Zhao was trying so hard to avoid danger just now... but was just worried that the hovercraft would get dirty?

I have to say...it's a really amazing angle.

Of course, no matter what, it was Bian Zhao who protected her during the earthquake just now, and Jiang Ran was very grateful for this favor.

Jiang Ran lowered his head and said, "Thank you."

Bian Zhao: "You're welcome."

It was rare to see Bian Zhao in such a good temper, Jiang Ran was a little puzzled, but just when he was about to say "How could I feel embarrassed", he heard Bian Zhao's cold voice the next second.

"This is the third favor you owe me."

Jiang Ran: “…”

Jiang Ran: "How come there are three now?"

Bian Zhao: "I borrowed your hovercraft twice and saved you once, so isn't that exactly three?"

Jiang Ran: "Didn't I agree to your terms the second time I borrowed the hovercraft?"

Bian Zhao: "Conditions are conditions, and favors are favors. These are two different things."

Jiang Ran: "...Okay."

Jiang Ran was silent for a long time, and after walking forward for about ten minutes, she finally couldn't help it and spoke out her true feelings.

Jiang Ran: "If you keep going like this, I won't be able to repay the favor I owe you."

Bian Zhao didn't even raise his eyelids: "Then pledge yourself to me."

Jiang Ran: “?”

Bian Zhao continued to control the hover car forward, but after a while he found that Jiang Ran was not catching up at all.

Bian Zhao turned her head without changing her expression, but Jiang Ran could already read the information from her unchanged expression.

For example, her emotion at the moment is: Why haven’t you caught up yet? Are you disabled?

Jiang Ran was silent for a long time, then asked with difficulty: "What does it mean to pledge your love to me?"

Bian Zhao said as a matter of course: "I've been doing some biological research recently, and I'm in need of experimental subjects."

Experimental subject?

Is this what she thought?

Jiang Ran's heart suddenly turned cold.

Seeing that Jiang Ran was still silent, Bian Zhao asked in confusion: "What's wrong?"

Jiang Ran looked at her with an indescribable expression, and after a long while he said, "Your business scope is quite broad."

"Well," Bian Zhao said, "Although I can try not to walk or talk now, it's really tiring to run all the way here just to see the Earth. It would be great if I could see it at home."

Jiang Ran: “…”

Jiang Ran: "Come on."

After this, Jiang Ran completely gave up talking to Bian Zhao.

The two of them just sat there in silence, one riding the hover car and the other walking forward.

However, not long after, a section of the cave passage suddenly became much narrower, and it seemed that the hovercraft could not pass through smoothly.

Bian Zhao controlled the hover car and hovered it in front of the narrow passage for a long time, not knowing what to do for a moment.

Just keep going forward. Even if the hover car can squeeze through, it will inevitably get rubbed and bumped, and it will inevitably become much dirtier.

If you put away the hover car, you either have to endure the wheelchair bumping on the ground, or endure the trouble of walking by yourself.

Jiang Ran stood by and watched the show for a long time. After a while, he said, "Come down and take a walk. It will refresh your mind and strengthen your body. It's so nice."

When Bian Zhao heard her voice, he suddenly raised his head and looked at her thoughtfully for a long time.

Jiang Ran felt the hairs on his body stand up: "Why are you looking at me like that?"

"I remember... you seem to owe me three favors, right?" Bian Zhao asked thoughtfully.

"So what?" Jiang Ran's voice gradually faded away.

Bian Zhao pointed a finger at her.

She said, “Now it’s time to return the first favor.”

Jiang Ran looked at her hesitantly, and just as he was about to ask how to repay her, he heard Bian Zhao's cold metallic voice slowly coming.

"Carry me over there."

Jiang Ran: “…”

She said indifferently: "Get lost."

Bian Zhao is not really disabled.

Asking her to carry a healthy person on her back for no reason...

Maybe she will do this when she has mental problems.

Seeing that Jiang Ran refused to agree, Bian Zhao had no way to force her to give in.

Bian Zhao hesitated for a long time, and finally succumbed to the cruel reality. She chose to stand up and take a few steps.

However, things didn't go as planned. After passing through that narrow stone path, the scenery didn't get much better. While the passage became slightly wider, it also suddenly became much lower. Jiang Ran and Bian Zhao could only crawl forward.

Bian Zhao failed to use the hovercraft successfully, and had to move on the ground. His clothes were covered with dust, and his expression was colder than usual.

Jiang Ran didn't care about her thoughts. He just took out the flashlight from his bag, illuminated the situation ahead, and moved forward carefully.

When the situation finally cleared up and they left that difficult passage, Bian Zhao, for the first time, did not release the smart wheelchair and hover car immediately.

They looked at the scene in front of them and were stunned for a moment.

After walking through the dark cave for a long time, I finally reached the depths of the cave and suddenly felt that everything was worth it.

What you see before you is a magical sight created by nature over thousands of years. Whether it is the texture of the rocks or the quality of the stone walls, they are all beautiful and rarely seen in the world.

Stalactites are staggered and hung from the top of the rock wall, and standing next to it is a moss-covered stone that looks like a human palm.

The base color of the rock wall is grayish white, but on it are neatly arranged green stripes, as if measured with a ruler.

There was a sound of dripping water nearby. When I walked closer, I found that it was an underground river.

The water in the underground river is very clear. Looking down along the light of the flashlight, you can clearly see the small stones under the water, and even the depressions above can be seen clearly.

"The water quality here is probably not much worse than that in Iceland." Jiang Ran sighed.

"There's the sound of water over there," Bian Zhao said, pointing to the other side. "Let's go over there and take a look."

"OK."

When Jiang Ran agreed, he secretly glanced at her lower body out of the corner of his eye.

Sure enough, in just a short while, the man was sitting in the wheelchair again.

Jiang Ran and Bian Zhao groped their way towards the direction where the sound of water came from. However, as the sound of water became louder and louder, they heard another strange sound.

The strange rustling sound rose and fell from time to time, but it gradually became louder as the distance got closer.

"What's that sound?" Bian Zhao asked.

"It's probably a cave creature," Jiang Ran guessed. "Judging from the sound characteristics, it's probably an animal. And it's so deep in the cave... It might be a bat."

"What are bats?"

Jiang Ran did not hide anything and began to explain science to Bian Zhao seriously.

However, Jiang Ran had just said a few words when Bian Zhao quickly took out the hovercraft and sat in it.

Jiang Ran paused for a moment.

Bian Zhao turned back in confusion: "Why don't you say anything?"

Jiang Ran carefully studied her expression and asked, "Are you afraid of bats?"

"How is that possible?" Bian Zhao said expressionlessly, "Don't make jokes all the time. It's boring."

Jiang Ran was not joking.

Bian Zhao's stuttering sound effects suddenly appeared, and it didn't look like he didn't care about the bats at all.

However, Jiang Ran didn't continue to embarrass others with this point, and they continued to move forward.

After walking a few steps forward, the strange noise became louder and louder.

What's worse is that as the cave passage became narrow again, Bian Zhao had no way to use the hovercraft.

Faced with unknown risks, they subconsciously slowed down their pace.

“Bang!”

Suddenly something fell straight to the ground from above.

"Bat!" Jiang Ran screamed in surprise.

At that moment, Bian Zhao jumped up from the wheelchair and hid behind Jiang Ran in the blink of an eye.

Jiang Ran: “…”

She slowly turned her head and looked at Bian Zhao behind her. There was no emotion on her face, but her action in that instant had already explained too many things.

Jiang Ran raised his hand: "Hi."

Bian Zhao quietly poked his head out and looked ahead. When he found that the scene he imagined did not appear, he immediately shook off Jiang Ran's hand and said as he walked forward, "What are you talking about?"

Jiang Ran: "..." Demolish the bridge after crossing it?

It was not until they both stood in front of the thing that had fallen that they finally confirmed that it was not a bat, but a cave frog.

Most of its body is green, with many small black protrusions all over it. Generally speaking...

Looks very ugly.

Bian Zhao took a look and covered his eyes.

A rare look of pain appeared on her face. She shook her head slightly and said, "Let's go over there quickly."

Jiang Ran looked at her reaction and agreed with a smile.

However, after taking only two steps, as the sound of flowing water got closer, the strange rustling sound started again.

Bian Zhao had experience this time, so she stopped in advance and said, "Turn off the light and wait until the cave frog passes by before turning it on again. I don't want to see its appearance."

Jiang Ran didn't refuse either.

When the sound got closer, I looked at the scene in front of me and suddenly found something wrong.

What was approaching from the front was not a small burrowing frog, but a huge black shadow.

In such a dark and deep cave, what kind of creature could be so huge?

Jiang Ran was so frightened for a moment that she didn't even dare to make a sound. She grabbed Bian Zhao's arm and wanted to run back.

However, at the same time, the black shadow in front of her seemed to be even more panicked than her. A ball of black mist suddenly jumped, and then ran back in the direction it came from.

What's going on?

Is that giant cave creature shy?

Jiang Ran was immersed in confusion, and his steps that were about to step back stopped for a moment.

Bian Zhao's hand had been held by Jiang Ran earlier, and his attention was diverted to Jiang Ran beside him, so he didn't even see the movements of the black shadow in front of him.

But she was originally waiting for Jiang Ran to say something, but when she saw that Jiang Ran had no response, she couldn't help but feel worried and confused.

Bian Zhao paused and finally opened his mouth. However, just as the word "you" came out of his mouth, the black shadow that ran a little further away in front suddenly let out a huge shout full of shock and panic.

"Help! There's a ghost!"

“Ahhhhhhhhhhhh—”

“…”

At this point, Jiang Ran, who had been hesitant and ready to move at any time, suddenly had no intention of retreating anymore.

At this moment, no matter how slow and nervous she was, she should have known that the huge black shadow in front of her was not a cave creature at all, but...

Several people gathered together.

and……

Judging from that very familiar cry...

Those few were even acquaintances.

Thinking of this, Jiang Ran held his forehead and called out the man's name: "Fu Bo."

The black shadow in front suddenly jumped higher: "Help! Why does this ghost still know my name? Ahhhhhh——"

Jiang Ran: “…”

It's already the interstellar age, but people are still so superstitious. Is this really okay?

The author has something to say:

Jiang Ran: Say it again? How do I look like a ghost?
