There was a "pop" sound.
After Liu Yiyi jumped into the cave, her brand new combat boots immediately sank into the blood.
She looked down and found that the blood from the corpses outside had almost all flowed into these underground caves.
Fortunately, the terrain at the entrance of the cave was relatively high, so there was no pool of blood under the feet. It was just that the ground on the ground became extremely sticky due to the flow of blood, and the blood flowed downwards along the passage.
Liu Yiyi's golden pupils can see things clearly even in the dark and are not affected by the darkness at all. In the dark environment, her eyes will automatically emit a golden glow, just like seeing a cat's eyes in the dark, like a pair of amber.
The other soldiers put down their night vision goggles and turned on the switches to adapt to the dark environment. After loading their guns and turning off the safety, they walked forward.
This cave was specially designed for the mutant rat leader. Because the leader is huge, the cave was dug according to his body size.
The passage is ten meters deep from the ground and 2.2 meters high, just slightly higher than the rat's head.
In this way, the group will not feel cramped when walking in the cave and can walk upright normally.
The passage extended downward at an angle. It was a bit difficult for the group to walk in the muddy passage, but it was fortunate that they had non-slip shoes.
The soldier in front was wearing a mask, with night vision on, holding his gun tightly with both hands, and turning on the infrared device, his eyes were vigilantly observing the surrounding situation.
Liu Yiyi appeared calm and composed, walking steadily in the middle of the team. Behind Liu Yiyi, another ten soldiers remained highly alert. They moved forward carefully while paying attention to the movements behind to ensure the safety of the team.
As the team continued to go deeper, the surrounding environment became darker and darker, and almost no light could be seen.
After walking about fifty meters forward, a pool of blood appeared on the road. The blood flowing down from above gathered here, forming a pool of blood about ten meters long, but it was unknown how deep it was.
At the end of the pool of blood was the corner of the passage, and the situation inside was completely unknown.
The air here gradually became humid, making people feel a little stuffy, and was filled with a strong smell of blood.
With no other path to choose from, they had no choice but to keep going.
The soldier walking in front did not hesitate to put one leg into the pool of blood, trying to test its depth.
He was seen shaking his legs gently a few times in the pool of blood, and after making sure it was safe, he jumped into the pool of blood with his whole body. It turned out that the pool of blood was not deep, only reaching his knees.
After standing firmly in the pool of blood, he looked back at Liu Yiyi and signaled to her that she could continue moving forward.
"Let's go." Liu Yiyi didn't care about this. Although it was dirty, the mission was more important.
The soldiers jumped into the pool of blood one by one with expressionless faces and walked forward with difficulty.
When it was Liu Yiyi's turn, she frowned, looked at the pool of blood in front of her with disgust, and then jumped in.
The blood in the blood pool was extremely thick, as if it was about to solidify, and had a sticky touch.
Every step Liu Yiyi took felt like she was stepping into a muddy swamp. What was worse was that blood seeped in through the gaps in her shoes. She could feel her feet being soaked in it. Her ten toes moved unconsciously, and the sticky feeling made her feel uncomfortable all over.
"hateful!"
Liu Yiyi cursed in her heart. She had always cherished her feet and took care of them normally, but now they were stained by the smelly blood. She was so angry that she walked around the corner with a gloomy face, only to see that the other soldiers had stopped here.
There were two forks in the road ahead. One was more than one meter high, and the blood in the blood pool was flowing into the hole continuously. The other was more than two meters high and was an upward slope.
Liu Yiyi bent down and carefully observed the one-meter-high hole.
The passage was only a few meters long and was divided into two entrances, one leading upwards and the other leading elsewhere. She guessed that this might be a tunnel dug by a rat soldier while escaping.
“Go uphill.”
The soldiers received an order to continue moving forward. The slope was not high. After only two meters, it turned into a long passage with no end in sight.
"Commander, there are some bodies ahead."
The soldier at the front whispered.
Upon hearing this, Liu Yiyi quickly walked to the front of the team. She saw many corpses lying on the ground in the passage ahead. Upon closer inspection, she found that they were all old acquaintances.
Among them, the majority were the corpses of mutant cockroaches, and there were also some corpses of rat soldiers.
It should be that the cockroaches also escaped in just now and started fighting with the rat soldiers.
"Forget about them, let's keep going!" Liu Yiyi said calmly.
Liu Yiyi's team continued to move forward along the passage. It was extremely dark here, and they could hardly see their hands in front of them, but fortunately they were well-equipped.
The passage was very long, as if it had no end. They had to quicken their pace and finally started to jog. Because of running, the blood in their shoes became sticky like dumpling filling.
Although their speed was not slow and each soldier was the best among the elite, Liu Yiyi was at the top of the pyramid.
But it still took them nearly 40 minutes and they ran nearly 10 kilometers before they finally passed through the long passage and came to a small round room.
This small room is actually a larger forked cave. Opposite Liu Yiyi, what comes into view is a row of eight holes of the same size and specifications.
Each hole looks exactly the same, making it difficult to tell which one the rat leader is staying at.
“Hehehe…hahaha…”
In the quiet environment, Liu Yiyi suddenly held her stomach and laughed, thinking that since the end of the world, every day she was either making things difficult for others or on her way to making things difficult for others.
Now, I've been played by a mouse!
"Did I come to the underground to rob graves?"
"It's just a rat hole, but you set up a maze for me. There are eight intersections! Are you secretly learning gossip, you dead rat?"
"Do I have to find a dragon point and point it out for you? I'm going to seduce you, you immortal!"
"You've dug so many tunnels in such a short time. You must be exhausted!"
Liu Yiyi was so frightened by the rat that she yelled and cursed for a few words, then she sat down on the ground, regardless of her fairy-like image, and took off her shoes and socks. The blood in her shoes had turned into sticky paste from her steps. The soldier next to her was very considerate and handed his water bottle to Liu Yiyi.
"Thank you. You guys clean up too."
"Yes! Chief! You're welcome, Chief!"
The team members washed their feet, poured out the blood plasma in their shoes, wiped them with paper and put them on.
