"You may be right. Our identities have not been exposed." Lu Rankong showed a thoughtful expression. "It seems that the reason why the Longte people stayed in Quye Prison is to guard the Kaleng Crystal in this lake."

"General Liu said before that the interstellar channel was opened by the Kaleng cannon. It should be that the Kaleng crystal here was used." Lan Yu said.

Lu Rankong was silent for a moment, then said, "If we exclude Liu Junjie and the others, the Longte man is among the group outside. He is one of them. Because only they can enter and leave the prison freely, and only they can know that we found the cave entrance yesterday. There are branch caves everywhere, and if someone was hiding somewhere and peeking, we wouldn't have noticed it at all."

"Prison guards...there are probably at least a dozen prison guards outside," Lan Yu said.

Lu Rankong said: "Not only the prison guards, but also the drivers of the engineering crawler vehicles, a total of 23 people."

Lan Yu stroked his forehead and said, "I think it's harder to find the Longte man among these twenty-three people than to find him among the six prisoners. After all, there is no chance to get close to them, unlike the prisoners, who can be together at any time."

Lu Rankong said: "But fortunately, we already have a general goal, which is better than knowing nothing. There are always opportunities."

He then asked, "Do you always carry that medicine with you?"

"I have it with me..." Lan Yu touched the inner pocket of her prison uniform.

"Well, that's fine."

Lu Rankong looked around and said, "Let's go and see if there are any other mysteries."

Lan Yu put on her shoes and said, "Didn't you find the way on the left just now? Then let's go to the right and have a look."

After saying that, he walked forward. After climbing over two rocks, he found that Lu Rankong did not follow him. He turned back and saw him looking at him coldly.

"What's wrong?" Lan Yu touched her face in confusion.

Lu Rankong narrowed his eyes slightly. "What's wrong? You were pretending to have a broken leg and wanted me to carry you, but when you were chased by the Crystal Devourer just now, you ran as fast as an ion cannon. You still have the nerve to ask me what's wrong?"

Lan Yu then came to his senses and began to insist on carrying him because she thought his leg was broken.

"I always said that I just had a skin cut. When did I pretend to have a broken leg?" he defended.

Lu Rankong sneered and said, "Don't you find it funny to say such things? Colonel K, who is known throughout the galaxy for his cold-bloodedness, would choke up when he speaks just because of a little skin injury?"

He sighed, "But I was careless for a moment and was fooled by you. Let alone breaking a leg, you wouldn't make a sound even if all the bones in your body were broken."

Lan Yu said solemnly, "I didn't choke up."

Lu Rankong crossed one hand over his chest and touched his chin with the other, looking him up and down, and said, "K, I suddenly feel that you can consider acting after you retire? With the performance you just performed, you will definitely win an acting trophy."

"A performance trophy means nothing." Lan Yu retorted sincerely.

I have too many trophies at home to count, and two of them were even taken away by the nanny and used as flower pots.

Lu Rankong walked forward, and when he passed by Lan Yu, he smiled and whispered, "Actually, if you call me brother, I will carry you on my back. There's no need to act like that."

After walking two steps, he turned back and urged: "Let's go, do you still want me to carry you?"

Lan Yu hesitated for a few seconds between continuing to argue and letting him think that she was acting, chose the latter, shut up, and followed him angrily.

There were also some big rocks on the left side of the lake. The two men climbed over the rocks and walked forward for a while, but found nothing.

"Let's go back. It looks like we have no choice but to ask the warden to dig us out." Lu Rankong said.

He turned around and saw Lan Yu twitching his nostrils, lowering his head to sniff his body, with his brows tightly furrowed.

"What are you doing?" Lu Rankong asked.

Lan Yu said: "Smell me, do I smell anything?"

Lu Rankong leaned in and sniffed twice, then said, "Yes..."

Lan Yu's face wrinkled up. "Just now, that crystal-eating beast spilled blood all over my head and face. I smelled a fishy smell."

"It's not a fishy smell, it's the natural smell of your body." Lu Rankong said.

Lan Yu sniffed her sleeves again and asked doubtfully: "The original smell? I don't have any smell..."

Lu Rankong looked at him for two seconds and then suddenly looked away. He looked at the lake with a vague look and said, "You smell..."

Lan Yu's heart suddenly started to ring with alarm bells. Could it be that her glands were loose and he smelled her pheromones?

He pretended to smooth his wet hair and touched the back of his neck.

Fortunately, the gland patch was firmly attached to the skin and did not move at all.

"Didn't I sleep with you in my arms these past two nights? I keep smelling that smell." Lu Rankong touched his nose.

"Who said we were hugging each other while sleeping? That was to keep warm. I used you as a heater." Lan Yu raised her voice instantly. "I was cold and I was leaning on a heater. Does that mean I was hugged by the heater?"

Lu Rankong said: "When you leaned against the heater, the heater smelled you."

Lan Yu glanced at him and couldn't help asking, "What's that smell?"

Lu Rankong turned his head and looked at him without saying anything.

"Say..." Lan Yu frowned.

Lu Rankong suddenly pointed ahead and said, "Hey, what's that? It looks a little different there."

His way of changing the subject was too clumsy. Lan Yu said coldly, "You said that if I didn't go crazy, you would take good care of me. Just now, you kept complaining after I recited a passage, and now you don't say anything when I ask you. I think I'd better continue to go crazy."

"Hey, don't." Lu Rankong said quickly.

"Then tell me, what do you smell?"

Lan Yu felt worried, hoping it wasn't what she thought.

"It's sweet and smells like the bag of shampoo I gave you. Isn't there a small bottle? It's for facial application. I opened it and smelled it, and it's like that." Lu Rankong said.

Lan Yu breathed a sigh of relief, but said in disdain: "Did you open the lid and put it under your nose to smell it?"

"No, no." Lu Rankong shook his head frantically.

Lan Yu snorted, turned around and walked back to the passage.

"Wait..." Lu Rankong stopped him, "That thing in front is a little different, let me go take a look first."

"Hey, aren't you just looking for an excuse to change the subject?"

"Why am I changing the subject? You're talking nonsense..." Lu Rankong pointed to the left side of the mountain wall and said, "Look, there seems to be a cave over there."

Lan Yu looked in the direction he pointed, and sure enough, there was a hole. It was impossible to tell how big it was. Only a small half of it was above the water, and the rest was submerged in the lake.

Lu Rankong walked into the lake, "Just wait here for me, I'll swim over and take a look."

"You just wrung out your clothes and you're going into the water again?" Lan Yu asked.

Lu Rankong asked curiously: "Is it difficult to wring out clothes?"

Lan Yu found it difficult to communicate with him, and waved her hand impatiently, saying, "Then go ahead, I'll wait for you here."

Lu Rankong quickly jumped into the water and swam towards that place. When he reached the cave entrance, he took a deep breath and dived into the water.

The surroundings became quiet, and the ripples on the water caused by Lu Rankong gradually subsided. Lan Yu stood alone on a rock on the shore, and suddenly felt a little regretful.

Thinking of the crystal-eating beast at the beginning, I regretted not following him to see the cave. The strange fish is not dead yet, who knows if it will suddenly appear again.

Lan Yu stared at the water while thinking about all sorts of things, and gradually, she began to feel anxious.

Several minutes had passed and the place was still quiet. Not only did Lu Rankong not show up, there wasn't even a bubble to be seen.

Calculating the time, it has been about five or six minutes. Even if he could hold his breath, he couldn't do it for that long.

His heart skipped a beat, wondering if he was drowning!

Thinking of this, Lan Yu decisively ran to the lake, dived in, and swam towards the cave.

When he reached the entrance of the cave, he took a deep breath, dived into the water, and swam in like a nimble fish.

He opened his eyes in the water, and swam while looking for Lu Rankong's figure. He swam for dozens of meters in one breath before floating to the surface, gasping for breath.

It looked like this was also a passage, but it was much wider than the first one. There were one or two tiny pieces of Kalends crystals scattered on the bottom of the water. The light of the water was reflected on the wall of the cave, flashing like scales.

"Lu Rankong, Lu Rankong." He shouted Lu Rankong's name deep into the passage. His voice echoed in the passage and spread far away.

Lan Yu gently paddled her hands and feet in the water, feeling a little more at ease.

There was no one in this section, so I thought he had already gone deep into the passage and was not in any danger.

Just as I was about to continue swimming forward, I heard the sound of water coming from the front, and suddenly a person emerged from the water deep in the passage.

Lu Rankong wiped the water off his face and asked, panting, "Didn't you say you were waiting for me? Why did you come in?"

Lan Yu said nothing.

Lu Rankong swam over quickly and said, "Let's go out."

The two swam out of the channel and returned to the lake and land.

"Where does it lead to?" Lan Yu asked.

Lu Rankong had already taken off his prison uniform and was about to unbutton his pants in a vest when he caught sight of Lan Yu standing beside him and withdrew his hand.

He twisted his prison uniform and said, "Further ahead is an underground waterfall, I don't know where it flows to. And there is no Kaling crystal in front of it, it's pitch black and I can't see clearly, so I didn't go forward."

Lan Yu took off her shoes and poured water, muttering, "I just told you to go out, but you insisted on going to see the hole, and you didn't find anything, and your clothes got wet again."

Lu Rankong said nothing and began to shake the water off his head. The water splashed on Lan Yu's face. He picked up a small stone and threw it at her, "Stop shaking your hair."

The two of them packed up, went to find the gas lamp, and prepared to go back along the passage.

Lan Yu looked at the glowing lake and asked, "What about this Kaling Crystal?"

Lu Rankong said: "I will ask the warden to report to the military and let them handle it themselves."

"Do you think the Longte people have already taken some of them out?" Lan Yu asked hesitantly.

Lu Rankong was silent for a moment, then replied, "Some of it must have been taken out. The interstellar channel was opened half a year ago. But no matter what, the Kaling crystals here must be taken back by the military. No matter how sturdy the starship is, it can't withstand the attack of the Kaling cannon."

Lan Yu returned to the starting point and looked for the gas lamp. When the crystal-eating beast pounced on the shore just now, he didn't know where he threw the gas lamp.

When Lu Rankong saw him searching in the cracks of the rocks, he followed him over to look.

"By the way, when the crystal-devouring beast was chasing you, were you screaming?" Lu Rankong suddenly remembered this and said excitedly, "You must have been screaming, right? I think I heard a sound."

Lan Yu stood up, looked at him incredulously, and asked, "Do you think I will scream?"

Lu Rankong observed his expression, which showed neither shame nor guilt. When he thought about the behavior of the man in front of him, he became unsure.

"Maybe I heard it wrong," he said.

Lan Yu sneered, "Did you always want me to scream and tremble, so you have this illusion?"

"How could that be..." Lu Rankong said.

Lan Yu lowered her head and continued to look for the gas lamp, saying, "You just hope that I can't be as good as you. You compete with me every day, openly or secretly, like a fighting cock."

Lu Rankong explained palely: "How could it be..."
