Chen Si's words were absolute authority in the team, and no one would doubt his judgment, although his judgment would occasionally be wrong. Hearing his words, everyone drew their weapons and held them in their hands. The more seriously injured were escorted in the center of the group, and everything seemed to be in order.

Nelson's expression was very strange, according to his and most of the Mi army's thinking, if the team had already suffered such heavy losses, it meant that the mission had failed. It should be retreated as soon as possible. However, he didn't see anyone hesitate in Chen Si or even in the team members other than him.

"Terrible Chinese!" Nelson muttered, and threw himself into moving forward. It's unthinkable to want to leave here alone. Not to mention that he couldn't find his way back, even if he did, he lacked the courage to go alone. Along the way, they basically stepped on the blood of their companions. Breaking away from the big team, the consequences can be imagined.

There is not much space for people to walk along the riverside, and many times they have to wade through the water. However, because in the process of falling, everyone threw away their backpacks, so they fell easily. Of course, the price of this ease is that there are no supplies on everyone. Even the searchlights that illuminated them had been lost, and the only lighting tools that everyone relied on were the miner's lamps on their hoods. Many people's hoods were also shattered, and some simply took them off, but fortunately there was plenty of oxygen under the abyss, and there was nothing wrong with it except for the smell of blood in the air.

The team that lacks supplies is not as confident as before, Chen Si also wants people to go into the water to salvage the materials that were discarded before, but the water surface is so big, and trying to salvage such a small piece of things is tantamount to looking for a needle in the sea, and after thinking about it, he gave up this idea. However, Chen Si was not very anxious, because he still had a bottle of nutritional tablets on him, which was enough for everyone to support one or two meals without any problems. As long as everyone moves quickly, the task can be completed before the food runs out.

Gu Fengchun carried Luo Xiaodan on his back and followed closely by Chen Si's side. When light sources are scarce, he is the team's beacon, guiding everyone's path. Leaning against the rocky riverbank, it is very inconvenient to walk.

"Chen Si, this road seems to have no end......" After walking for I don't know how long, Gu Fengchun frowned and said. He had forgotten how many bays he had turned along the river, but he couldn't see any way out, the river was still turbulent, the banks were still steep and high, there was no other way out, and there were still many skeleton wrecks on the ground from time to time, which added a lot of gloom to everyone's hearts.

"You're right, I'm afraid we're in a loop again." Chen Si lowered his voice: "Do you remember the two waterfalls we saw above?" ”

"Yes, that's true." Gu Fengchun scratched his head and said puzzledly: "What does it matter? ”

"When we fell, we saw a waterfall, but what about the other waterfall? Why have we walked for so long without seeing it? Chen Si asked Gu Fengchun rhetorically.

Gu Fengchun thought for a moment, then shook his head and said, "I don't know." ”

Chen Si glanced at him and said, "Because that waterfall doesn't exist at all." ”

"How is that possible?" Gu Fengchun's face was shocked. "If it doesn't exist, then how can we see it? Moreover, Xiao Dan also saw it! "Luo Xiaodan has a delusional pupil, if there is a waterfall that does not exist, then she must be able to see what is behind the illusion at a glance.

"Nothing is impossible." Chen Si groaned and said, "The reason why Xiao Dan didn't find out that there was a fake in this is because it was a mirror image, and it was the reflection of the waterfall we saw. Chen Si was carefully thinking about the wording.

"Do you have any proof?" Gu Fengchun looked at Chen Si and said.

Chen Si shrugged his shoulders and said, "You pay attention to your feet, every distance you have walked, after walking for a while, you will find that some places have already been walked." "Chen Si's observation skills are very sharp. It's not easy to spot such a problem in a situation where light is limited.

Gu Fengchun raised his head and looked around at his surroundings, and immediately took a breath of cool air. He had followed the group five or six turns, but he suddenly realized that his current position was not far from where they had just begun to fall.

"When did you find this?" Gu Fengchun looked surprised.

"It was also just now, when I made a turn last time, that I realized that my surroundings were a little familiar, so I made a mark on the rock, and then, just now I saw the mark I made, and I concluded my idea." Chen Si's tone was still very calm.

"So what do we do?" Gu Fengchun said worriedly: "It's not a way to go on like this. ”

Chen Si nodded and said, "I'm looking for that tipping point, and we're going to re-walk the tipping point of this journey repeatedly. Chen Si frowned and said, "But it's strange, I feel that this critical point is not fixed, and we always go a distance farther than before we start a cycle again." When he said this, Chen Si's expression became very serious: "If we don't find the critical point and find a way to get out of this dilemma, then we will be completely lost in this place." ”

Gu Fengchun nodded. As this cycle intensifies, the distance they travel in each cycle is extended by a part, and the position of the tipping point becomes more ethereal, and the possibility of finding the tipping point becomes more ethereal.

"Maybe we're on the wrong path?" Gu Fengchun pondered for a while: "Maybe we should go in a different direction." ”

"Oh?" Chen Si really wanted to hear some practical suggestions from Gu Fengchun's mouth.

"As we went down the riverbed, we came back to square one every other and the distance became longer each time. So reversely, if we change direction, then there is no other cycle, there is no short-range cycle, and then each time the distance becomes shorter, and finally ......"

"Eventually, we'll cross that tipping point! Find your way out! Chen Si's tone was very excited. He had already gotten a possibility from Gu Fengchun's conjecture. But that's just a possibility. However, if this possibility exists, it is already worth Chen Si's attempt.

"Stop, go the way you came." Chen Si stopped and turned around and said.
