The water of the Bijiang River is very urgent, and if you go down rashly, it will definitely disappear without a trace in an instant, and there will be no time to see the light of day again. Therefore, the only road in front of everyone is the seemingly safe, but in fact, it may be more difficult - enter from the first floor of the building, and then enter the negative floor by diving. Only this time, some people's disadvantages are about to turn into advantages.

Among the ten people, the more "slim" figure, only Qiao Wu, Bai Yunlian, Wu Nanrong three people, but Qiao Wu wants to control this clumsy helicopter, the doppelganger is lacking, Wu Nanrong does not know water, therefore, Bai Yunlian has to take on the "big responsibility", after all, this building has been somewhat deformed, and many entrances and exits may be narrowed, in this case, it is natural to find a person with a "slim" figure to explore the way appropriate.

Wei Yilin divided everyone into two groups, the first group, led by Qin Tianwu, and the team members were, Qian Zhenshan, who was the best at short soldiers, Bai Yunlian, who was the shortest, and Xiao Tian. The rest are all in the second group, ready to support.

Fortunately, as early as Ren'an, Wei Yilin was prepared for the situation that he might encounter in Yuanzhou, everyone brought an oxygen tank and a few pairs of flippers, so the difficulty coefficient of this operation has dropped a lot, but due to the limited conditions, everyone has no guns that can be fired underwater, so the only self-defense weapon for everyone is the saber they carry.

Although the Bijiang River is the mother river of Yuanzhou, its milk is really difficult to leave a good impression on the children of Yuanzhou. Because the visibility of the river is almost zero, and there is a strong suffocating smell in it, and the culprit of this fishy smell is hidden in this garbage, which can be grabbed with a gentle flick of the hand. These filth, which have been soaked in the river water for an unknown number of days and moons, have turned the blue river water from the milk that can feed people to dove wine that takes people's lives.

Fortunately, there is a "great" invention of the oxygen tank, otherwise, I am afraid that before a few people reach the negative layer, they will be drugged to death by this highly poisonous "dove wine" first. Several of them keep their bodies about fifty centimeters above the surface of the water so that the fins can exert more force, and at the same time, they also help themselves to have a deeper understanding of the underwater situation.

Wei Yilin on the helicopter would not have known that under this seemingly calm river, there was such a turbulent vortex hidden, so that it was only a little bit possible to make him, separated from his good brother heaven and man forever, and make himself a winged bird that had lost his other wing forever.

It turned out that the marble floor under the water had gaps, and after a long time of soaking, a lot of aquatic plants had grown, and among these aquatic plants, there were many things hidden enough to scare people to death - such as a hand!

This "hand" grabbed one of Qian Zhenshan's feet at once, Qian Zhenshan's water quality is the worst, and when he went down to explore the road, he had some hidden worries about the turbid river, so he panicked and struggled a few times, but this made the "hand" grasp tighter and tighter, but such a "large" range of struggle, but only on the water surface, made a few small waves, compared with the original waves on the river surface, it is really insignificant.

But despite this, Qian Zhenshan was struggling, and hit Qin Tianwu who was swimming beside him with one arm. Qin Tianwu is the leader of the group, and his sense of responsibility is naturally stronger, although this is just a "small thing" that he will encounter from time to time in swimming, he still turned his head and took a look, and the increasingly chaotic turbid river quickly aroused his vigilance, so Qin Tianwu waved his hands, respectively held the ropes tied to the two people swimming in front, and pulled three times - this is a signal of urgency.

The two men immediately stopped, and their heads popped out of the water, so that the three of them could clearly see each other's sign language. Qin Tianwu made a few gestures, and then plunged into the water, and the other two also fell into the water again from two different directions, and the three of them formed a semicircle, slowly approaching Qian Zhenshan from three directions.

Qin Tianwu gently hugged Qian Zhenshan, who was still struggling, from behind, his strength has always been great, controlling Qian Zhenshan is like controlling a domestic dog, although it is a little difficult, but it is still not a problem, and Xiao Tian and Bai Yunlian sneaked under Qian Zhenshan from the other two directions, where there is a very lush cluster of aquatic plants, just like an octopus, several tentacles of the "octopus" are wrapped around Qian Zhenshan's left leg, and Qian Zhenshan's struggle just now just made these "tentacles" become tighter and tighter.

Since this place is close to the bottom of the water, the visibility is slightly higher than in the middle of the water, so Xiao Tian and Bai Yunlian easily exchanged glances, and the two of them swung their knives at the same time, cutting the tentacles little by little. But I don't know if it's because it's inconvenient to use force in the water, or because the tentacle is too strong, the two tossed for a while, but they still couldn't cut off even one tentacle.

Fortunately, Qian Zhenshan had calmed down at this time, and the debris raised by his struggle had slowly precipitated, and the visibility had also improved a lot, which was good news for the two people who were cutting work.

If these four people knew what was going to happen next, their attitudes towards this aquatic plant might be completely different.

I don't know how long it tossed, those tentacles were finally cut off, and everyone continued to hurry, because it had taken a lot of time just now, so in order to get the assault boat out before the oxygen ran out, everyone sped up the speed of travel regardless of the danger. But despite this, they were not able to enter the building before the first drop of rain fell. The raindrops pierced the already cold river water like arrows, making it even more biting, and the harsh wind, again and again, set off bigger waves on the river, and it was also proud.

The interior of the building was dim and abnormal, although the strong flashlight was turned on, but this pillar of light was forcibly "retained" after rushing forward for less than half a meter, and the narrow passage made it impossible for the four of them to maintain the "round" formation just now, and they had to change to a long snake formation. The first is naturally Bai Yunlian, followed by Qian Zhenshan, followed by Qin Tianwu, and finally Xiao Tian.

Most of the departments on both sides of the passage are open, but what can be sprayed out of the gate is a stream of cold water like meltwater from a snow-capped mountain, and this water flow is not clean, and from time to time, it brings out some sundries, such as books that have long been soaked and deformed, pens attached to many small creatures, and so on. But you would be wrong to think that these are the "gifts" that the building has for visitors. Because this building is very, very "hospitable".

A pitch-black thing, suddenly rushed out of a department on the right, unbiased, hit Bai Yunlian's waist, this outward flow of water, already surging, so out of balance Bai Yunlian, was suddenly pushed by this thing on the other side of the wall of the corridor, fortunately, she quickly regained her composure, grabbed this thing with her left hand, and stabbed hard with the saber in her right hand.

It was a mangled corpse, the body had become ugly from the long soaking, and the clothes on it were indecipherable, and they were tightly attached to its skin. Qian Zhenshan in the back hurriedly caught up, the cold light flashed, and the body was in a different place, and then he reached out and fished out the head from the water, and shone it at the lamp worn overhead, but this head is also difficult to identify, it is impossible to identify at all, the corpse died as a healthy person, or died as an infected person.

Seeing Qian Zhenshan looking at herself, Bai Yunlian thought that he was asking if he was injured, so she shook her head, but in fact, what the latter wanted to ask was: Can this virus survive in the river water, and if they fall into the water without strict precautions, will they be infected?

After pushing the body away, several people continued on their way. But I didn't expect that this weekday walk, which was only a two-minute walk, now took several times as long and has not yet been completed. It turned out that there was suddenly a big cabinet in the water, and there were a lot of messy things stuffed on top of the big cabinet. If you want to overdo it, you have to knock them down first.

But most of these things have sharp corners, or have been artificially polished out of sharp corners, and these sharp parts, after years of soaking, have long been stained with many bacteria and viruses......

Bai Yunlian consciously got out of the way, this kind of tricky thing didn't need her to deal with, and she didn't want to deal with it, Qian Zhenshan behind her also thought so, so this obstacle array was directly exposed to Qin Tianwu's eyes, the latter stepped forward, and then with a strong flashlight, carefully checked these obstacles, and let the three of them swim into the offices on both sides of the corridor to explore whether there was an alternative road.

Not surprisingly, the layout of this first level is exactly the same as on the floor plan - there is no second road to replace. Qin Tianwu reluctantly glanced at this obstacle array, and waved his hand to signal everyone to go back, because the cost of demolishing it must be not small, and this choice, he is not easy to make.

Wei Yilin was a little annoyed about the fact that half a tank of oxygen was consumed and nothing was obtained, fortunately, there was oxygen production equipment on the helicopter, and the oxygen consumed could be replenished in a short time.

"We can break open these two windows. The risk of doing so is much lower than getting rid of those obstacles. Qin Tianwu gave his opinion, because the staircase, not far behind this obstacle array, as long as the anti-theft net of the window between the two of them was removed, they could successfully reach the staircase.

It didn't take long for the helicopter to fly to the side of the building, but now, the river was rising, and the window, which was more than a meter high from the ground, was also flooded for most of it at the moment, only a small part was exposed outside, and this little bit was still flooded by the waves from time to time.
