,!

"Didn't you say that there will be an exit from the maze?"

"Yes, but this cave is too huge. The place we just passed is just a main cave, and between the main caves, there are many intricate caves in the caves. It is very likely that our way out is in those small caves.

Inside, the probability of finding an exit among thousands of small holes at once is one in ten thousand."

"Then let's look for it quickly. Why are we wasting time?" Ruo Xianxian urged as if she didn't want to stay in one place.

"If we are looking for it, we must first determine the structure of the cave to see if it is a place of life or death. Only after determining the nature of the cave can we conduct a planned search. If we are lucky, we may find the exit in a few weeks.

If we are unlucky, it may take three to five years, or we may not be able to find an exit in our lifetime." Zhou Sen said calmly.

"Ah...then...then...what should we do?" Ruo Xianxian stammered and looked at Zhou Sen.

"First of all, we need to calm down. Only with clear thinking can we find a way out; secondly, we need to save food, because there is not much food in my Qiankun Ring; finally, we no longer need to worry about external things.

, because we are unable to protect ourselves and there is nothing we can do, so whether it is Yue Ning or Shen Huimin's comfort, we can only leave it to fate."

"Yue Ning...Yue Ning is lucky and will be fine. Zhou Sen, please think of a way... I won't bother you... Calm down now and think of a way..."

Zhou Sen nodded and summoned a lot of daily necessities from the Qiankun Ring.

"All our food is here. If we save a little, we should be fine for two months..."

After Zhou Sen counted some daily necessities, he took out more than a dozen demon cores and embedded them on the cave wall. Immediately, with the cave as the center, dozens of feet around became delicate, and all kinds of strange stalactites appeared.

One show.

Afterwards, Zhou Sen searched the area again and found a water source with an undercurrent as a convenient place. In order to avoid Ruo Xianxian's embarrassment, he also hung a carpet as a barrier.

After the arrangements were made, Zhou Sen summoned the tent again as a place for Ruo Xianxian to sleep. As for himself, he could just make do with a carpet.

"You clean up after yourself, I have to go to work."

"Ah...you want to leave here?" Ruo Xianxian suddenly became nervous when she saw Zhou Sen picked up a pen and paper and jumped into the cave.

"The geographical environment of this cave is extremely complicated. I must master its structure before I can figure out a solution."

"Why don't you take me with you?"

"We can't work with you, because many caves can only be entered by one person, and bringing you with you will not only consume your physical strength, but also greatly reduce your efficiency, and our food can only support two people at most.

months, so we must hurry up."

"But...but..."

"I will not abandon you." Zhou Sen stared at Ruo Xianxian with his deep eyes and said every word.

"I know." Looking at Zhou Sen's determined gaze, Ruo Xianxian's face turned red for no reason and she lowered her head.

"If there is danger, just shout loudly, and I will rush here as soon as possible... And, take this sword! Of course, you don't have to worry for the time being, I will start from here." Zhou Sen from Qiankun

A flying sword was summoned from the ring. This sword was the flying sword of a disciple of Leiyin Mountain.

"Um……"

Ruo Xianxian held the long sword and watched blankly as Zhou Sen began to work.

Ruo Xianxian saw that after Zhou Sen jumped down from the cave, he began to observe the cave. He observed very carefully, tapping the rocks from time to time, testing the water temperature with his hands, or holding his breath to feel the movement of the airflow...

During the observation, Zhou Sen would constantly record some data with pen and paper.

Ruo Xianxian sat on the hollow, looked at Zhou Sen, and played with the long sword in her hand in boredom.

This man always gives people a mysterious feeling.

…

This is a huge computing project.

Zhou Sen had to determine from the composition of the rock the cause of the original formation of the cave and the direction of the river erosion. By observing the air flow, he could determine whether the cave was connected to the outside world.

Zhou Sen's observations were very detailed. He found out the rock composition and air flow of the cave, and he didn't even miss the water.

When he was at the Moling Snow Leopard Cemetery in Moling, Zhou Sen felt the magic of nature.

There is no doubt that there are countless underground rivers in this huge cave. In this huge underground tributary, there must be an underground river leading to the outside world. Now, Zhou Sen needs to synthesize all the data and calculate a safe

's export.

In addition to the composition of the cave, Zhou Sen also needs to draw the plane of the entire cave. Only in this way can he not get lost and avoid repeated work. In this kind of calculation, if you are lucky, you are likely to encounter a

exit.

Zhou Sen's workload is very heavy.

At the beginning, when Ruo Xianxian saw the stack of drawings and calculation formulas that Zhou Sen was waiting for, she didn't care. But in the next few days, Zhou Sen would bring stacks of drawings when he came back.

Only then did I realize that this was by no means an easy thing.

one day!

Two days!

Three days!

…

Eight days have passed. During these eight days, Zhou Sen was overloaded with work and barely said a word to Ruo Xianxian. The stack of drawings became thicker and thicker.

At the beginning, Ruo Xianxian was still worried that Zhou Sen would take the opportunity to molest her. You know, this place is so chaotic. However, Zhou Sen had no idea about this at all. He was too busy.

When he returned to the cave to sort out data, he basically worked in the main cave.

On the ninth day, Zhou Sen returned to the cave, sat cross-legged on the carpet and started to calculate some data. Ruo Xianxian brought Zhou Sen a cup of steaming boiling water and some dry food. These days, Ruo Xianxian also realized that they would not be able to think about it in the short term.

After going out, she began to decorate the small cave and set up a small stove. Every time Zhou Sen came back, he would bring her some small firewood dried with super powers. There was not much firewood, but the quantity was extremely large.

Not much, but it’s no problem to boil a cup of boiling water to drink occasionally, which makes the cave a little more lively.

"Zhou Sen, eat something. You haven't eaten for eight days."

"Thank you." Zhou Sen didn't look up, reached out to take the cup, took a sip, and then devoted himself to the vast and complicated calculations. Although Zhou Sen is a top-level scientist, he relies on light most of the time.

Calculate by brain, not by hand.

"Zhou Sen, you have to eat something." The slender catkin grabbed Zhou Sen's hand.

"I am a person with super powers. I can do without food for ten and a half days, but you are a mortal. You can't do without food for a day. You'd better be more economical." Zhou Sen sighed, raised his head, and looked at Ruo Xianxian.

"Are we unable to go out?" Ruo Xianxian suddenly realized something was wrong.

"It's hard to say." Zhou Sen gently patted Ruo Xianxian's hand and comforted her.

"Tell me your calculations."

"It's very complicated... The formation of this cave is very strange. On the cave wall opposite us is a huge rock with a diameter of more than five kilometers and an oval shape. The underground river has eroded a huge rock around it.

The ring-shaped cave is surrounded by rocks. The cave wall we are leaning against is surrounded by huge rocks. Its composition is also very complex. The huge rocks are mixed with thick layers of soil. After years of erosion,

There are tens of thousands of small caves scattered among them, connected in series and intersecting with each other, forming a maze of ring caves... If we are lucky, maybe we can find a way out of the cave..."

"What if you are unlucky?" Ruo Xian's bright eyes stared at Zhou Sen.

"Bad luck...haha...my luck has always been good."

"I'm asking, what if we are unlucky?" Ruo Xianxian asked reluctantly.

"We will starve to death here. Of course, it may take a long time to really starve to death, because there are many small blind fish in this cave..."

"Those fish that are about the same size as the tip of a needle?" Ruo Xianxian laughed dumbly.

"Yes." Zhou Sen nodded awkwardly.

"Zhou Sen, I want to ask you something." Ruo Xianxian stared at Zhou Sen seriously.

"What's up?"

"I want to die in front of you."

"...We will not die."

"Zhou Sen, I'm serious, promise me! If you die, I will be lonely and scared. If I die in front of you, I will feel more at ease." Ruo Xianxian's expression was extremely serious.

"Our food can last for two months, don't worry, it's only been nine days." Zhou Sen sighed and said with relief.

"I know, in fact, our food can only last a month. Look at your appearance and see for yourself!" Ruo Xianxian took out a small mirror from her bag and handed it to Zhou Sen.

"What are you looking at...ah..."

Zhou Sen looked into the mirror and was startled. He saw himself in the mirror with sunken eyes, like a black-armored demon whose soul had been sucked out by an ebony sacred wood sword.

"Zhou Sen, although you are very powerful, you are only a junior superpower user and have not yet reached the legendary level of inescaping. What's more, your high-intensity work every day now consumes not only your physical strength, but also your energy. In a few days,

If you don’t eat, I’m afraid…”

"Um."

Zhou Sen nodded, picked up the dry food, chewed it carefully, and swallowed it slowly with boiled water.

The atmosphere became inexplicably tense.

Zhou Sen has always been an optimistic person. He never thought that he would be trapped here, but now, he has to think about this problem.
To be continued...
