In the end, Xu Yang didn't argue with Jiang Ran.

Seeing how embarrassed he was, he said contentedly, "Just tell me, what do you want to borrow?"

Jiang Ran looked at his face, confirmed that he really didn't care, and then whispered, "I want to borrow a ball."

"Follow the ball? Don't you have one?"

"Yes, I want to borrow it," Jiang Ran said. "I hope to keep the tracking ball in a fixed place for the next few days instead of having it follow me around all the time."

"Where to put it? Why do you do this?"

Jiang Ran glanced cautiously to the side upon hearing this. After confirming that no one was paying attention, he continued in a low voice, "Just now, when I was looking for the downstream exit at the volcanic pool, I noticed a dome on the side of the volcano. This is often a sign of a volcanic eruption. Judging from the height of the dome, the eruption shouldn't be far away, probably within this week."

Xu Yang immediately sat up straight.

This is a big deal.

He glanced to the side before turning back and asking seriously and solemnly in a low voice, "Are you sure?"

"Yeah." Jiang Ran nodded. He glanced over and noticed that Ren Xiayang seemed to be regaining consciousness. He leaned closer to Xu Yang's ear and said, "My teacher told me this. I saw the photos he took, and the dome there is exactly the same as the one I just saw. There's no way it can be wrong."

"That's indeed important," Xu Yang turned his head slightly and whispered in Jiang Ran's ear, "Do you want to place the tracking ball in the crater to observe its eruption so that everyone can avoid it in time?"

"That's right," Jiang Ran said, "but according to regulations, the video footage taken with the ball will be used as a reference for the investment case and cannot be moved without permission, so I came here to discuss this with you in advance."

Xu Yang nodded: "Okay, I agree."

Jiang Ran was very happy, but he still lowered his voice: "Thank you so much!"

"You're welcome," Xu Yang waved his hand, glanced to the side, and asked, "But why didn't you say this in front of everyone?"

"This matter is neither small nor big. The volcano isn't about to erupt yet. As long as we leave in time, we'll be fine. I don't want to cause anyone to worry for no reason."

"Wait," Xu Yang discovered a loophole. "If nothing will happen if we leave in time, why do we have to place a tracking ball to observe the situation?"

Jiang Ran paused for a moment when asked, but she quickly continued, "No matter how small the possibility is, it's 100% certain if it happens. I'm just being safe."

This answer made Xu Yang frown.

He found it a little strange, but logically he couldn't find any fault with it.

Seeing that he didn't answer, Jiang Ran asked quietly, "Do you think it's okay?"

Xu Yang thought for a moment and said, "You're worried that everyone will worry, but if your tracking ball suddenly disappears, aren't you afraid that everyone will find it strange?"

Jiang Ran frowned when he heard this: "But there is no better way."

"It's not that there is no way."

"You mean..."

"Give me your backpack."

Jiang Ran didn't ask any more questions. He stood up and went to the shore to get his bag.

After Xu Yang took the bag, he rummaged inside for a while and took out an empty box used for bombs.

Jiang Ran was confused: "This is..."

Before he finished speaking, Xu Yang pressed the bottom of the box and took out a brand new follow-up ball from the hole that suddenly appeared.

Jiang Ran: “…”

She looked at Xu Yang with a complicated expression: "Why did you secretly put a tennis ball in my luggage?"

Xu Yang remained calm: "This episode is mainly for testing. The tracking ball is an important tool for providing video footage, so of course we have to make a backup in advance."

"I understand this, but..."

Jiang Ran's expression was very subtle: "Why don't you put it in your own backpack?"

Xu Yang subconsciously rubbed the straps of his backpack. "It's just spreading the risk. You see, my backpack was lost during the snowstorm. Fortunately, I made this backup, otherwise it would be very troublesome now."

Jiang Ran looked at his expression and said nothing.

Xu Yang raised his eyes and asked, "You don't believe it?"

Jiang Ran laughed twice: "Of course I believe it."

No way.

While everyone was taking a nap, Jiang Ran ran to the volcano and placed the tracking ball on the edge of the crater.

After debugging her brand-new tracking ball, Jiang Ran connected her own computer to the ball's screen. After ensuring she could remotely see the volcano's movements on her computer, she hurried back to the hot springs, her backpack on her back.

Forty degrees Celsius is a relatively high temperature in hot springs. Although it can relax muscles and promote blood circulation, it is not suitable for soaking for too long.

After everyone took a short nap, they woke up just as Jiang Ran was returning.

Fu Bo was the first to see Jiang Ran who had just returned: "Where have you been?"

Jiang Ran waved his hand: "Go and do good deeds."

Fu Bo: “……?”

"Alright, get up." Jiang Ran deliberately avoided the topic. She urged, "No matter how comfortable the hot spring pool is, it's dangerous next to the volcano. We have to rush to the ice field before daybreak. It will be much safer there."

Upon hearing this, Ren Xiayang rarely started to act like a spoiled brat.

He stayed in the hot spring pool and bargained with Jiang Ran: "How about lying there for another twenty minutes?"

Jiang Ran's expression paused, then he turned and smiled at him, "Iceland is rich in seafood. Capelin is especially suitable for grilling, and cod is delicious when stewed. Not to mention salmon. Slice it and mix it with some seasoning. Even if you eat it raw, the taste is already amazing."

The more Jiang Ran spoke, the brighter Ren Xiayang's eyes became and the wider his mouth opened, almost drooling.

However, at this moment, Jiang Ran changed the subject: "It's a pity that these aquatic products are only found in the glacial areas. They are definitely not seen on the volcano. Since you want to stay here for a while..."

Before he could finish his words, Ren Xiayang hurriedly walked to the shore and put on his clothes.

As soon as he finished packing, he began to urge others: "Hurry up and pack your things! Let's get going! Every minute you stay here is a minute more dangerous!"

Jiang Ran looked at this scene and smiled with satisfaction.

While Ren Xiayang was busy running around urging everyone, Jiang Ran had some free time and was standing leisurely by the side watching the show.

As she looked at everyone in the hot spring pool, Xu Yang, who had dressed early and gone ashore, was also looking at her.

Looking at the leisurely Jiang Ran, Xu Yang touched his chin.

Judging from Jiang Ran's performance alone, she didn't seem to be very nervous about the volcanic eruption, but rather seemed to be just performing superficially.

I deliberately show that I care, and then I just let it go, ignore it, and let everyone go about their own business.

It looks weird no matter how you look at it.

But Xu Yang didn't have time to think about these things.

Not long after, everyone packed their clothes and luggage and followed Jiang Ran on the road again.

When a volcano is not erupting, it is much safer than a glacier, but it still hides many invisible dangers.

While walking beside the volcanic pool, Jiang Ran reminded everyone in advance to be careful with the soil that looked very soft.

Fu Bo was puzzled: "Why? Will it sink in like a swamp?"

Jiang Ran gave him a funny look and said, "Not only will it make your feet sink into it, it will also make your shoes and feet melt together."

Fu Bo: “……!”

This is a little scary.

Seeing that his threats had worked, Jiang Ran explained, "Don't be fooled by the softness of the soil; it's because it's at boiling point. Melted soil is certainly soft, but once you step on it, you might not be able to pull it out."

Xu Yang knew that since she said that, there must be a way, so he asked at the right time: "Then what should we do?"

Jiang Ran pointed to the ground and said, "The test is very simple. Once you see suspicious soil, step up gently and press it down with your boot... Don't use too much force. If the soil feels very soft and hollow, then it must be boiling underneath."

Jiang Ran's explanation was very thorough and the preventive measures were very detailed. Everyone listened carefully to every word, slowed down their pace on the road, and followed her closely. In the end, they didn't really encounter any major danger.

Before the sun set, everyone finally managed to leave the volcanic area and arrived at the ice field area.

This was the second day on Earth, and they finally arrived at the originally scheduled landing site.

"It's getting dark." Jiang Ran looked up at the sky.

"It's a good time to make dinner." Ren Xiayang immediately added enthusiastically.

Jiang Ran looked at him amusedly, then looked at everyone around him.

Everyone's face was full of anticipation, even Xu Yang was no exception, with a faint light between his brows.

"Okay," Jiang Ran agreed, determined to keep his promise. "I just cut some sheep fat, and then I'll go get some dry firewood and start the fire."

"Go to the ice field and see if you can catch any fish. We can grill them tonight!"

“Wow!”

"Yeah!"

“…”

Jiang Ran looked at everyone who was so excited, and his mood became brighter.

After leaving the most dangerous glaciers and volcanoes, life on the ice field will be much more peaceful. All we have to do now is set up camp honestly.

Thinking of this, Jiang Ran took advantage of everyone's inattention and secretly glanced at the computer screen.

The volcanic pool was barely calm, with only a fiery red bubble bursting out from time to time.

When will the volcano erupt?

Jiang Ran was very much looking forward to it.

The author has something to say:

【Small Theater】

Jiang Ran: I am playing with the ball for everyone’s safety.

Xu Yang: Really? I don’t believe it.

——

Xu Yang: I put the ball in your backpack so that the program can run smoothly.

Jiang Ran: Really? I don't believe it.
