The G1 floor is built underground, and the air circulation is all centrally air-conditioned, so the ventilation system is very complex, and in order to make it easy for maintenance personnel to enter, the ventilation ducts are relatively wide, and some vertical connections are also equipped with ladders for climbing.

Liang Yi took the lead, Luo Guangcheng, Tang Tian, Song Yinyin, Ye Qiu, and Gu Yicheng followed behind in order. The six of them climbed forward step by step, walked in a straight line when they encountered a fork, and went up the stairs when they encountered a staircase.

After 30 minutes.

"Oh, no, take a break, take a break, take a break, Sir Liang." After all, Luo Guangcheng was not young, panting, sweating, and said that he didn't move anything.

The ventilation duct is only big enough for one person to pass, and if the front is blocked, the back has to be stopped.

"That's right, Chief Liang, where is the exit, we've been climbing for more than half an hour......" Tang Tian behind Luo Guangcheng was also tired and sweating.

Song Yinyin's face was already pink due to lack of oxygen, and although Ye Qiu and Gu Yicheng were in good physical condition, they were also faintly tired in their expressions.

Liang Yi only knew how to hurry up, but forgot that there were still old men and women behind him, "I'm sorry, rest in place for 7 minutes." "The watch reads:

PM 19:53.

"Chief Liang, where are we now?" Ye Qiu took out the kettle, took a few sips of it himself, and then handed it to Song Yinyin.

Liang Yi said: "Not counting the forward distance, only counting the distance of climbing, it is about 3m higher than the G 1st floor, fast, it is almost the first floor, and it will probably have to climb the stairs again." ”

"Huh? Oh my God, I've been crawling underground for so long, my old bones are almost tired and falling apart......," Luo Guangcheng complained in a mournful voice.

Ye Qiu said angrily: "I said Old Man Luo, if you don't stop at the next intersection, and then you will follow after we pass, so that you will fall behind, first, you will have the motivation to catch up when you see us climbing away, and second, if you can't climb, you will stop and rest by yourself, so as not to block our road and drag us back." ”

"You...... You, you, you! I am the backbone of the country, a pioneer of advanced science, and I have been personally received by the prime minister, and my worth is worth as much as a division of the army! You know what I mean? My life is precious! ”

Luo Guangcheng should be telling the truth, but it is also unpleasant.

Ye Qiu said disdainfully: "It's all a life born by your parents, why is your life precious?" What about a division? How many people can there be in a division? Thousands? Tens? I don't think you've ever seen a big battle, there are hundreds of thousands, millions of infected people outside, and a single person can scare you to death with a howl! ”

Luo Guangcheng trembled with anger: "You...... You're a policeman. How much is the number, I will go to the Ministry of Justice to sue you and remove you from your post! ”

Ye Qiu said casually: "HN943301, go sue me!" I'm the one who wants to do a big business with Chief Liang now, who is rare to be a policeman? ”

"It's too unqualified, it's too unqualified!"

"Teacher Luo, don't be like him, Xiucai meets Bing who can't be explained, they are intellectuals in the old society, foul language, advocating violence......"

Tang Tian scolded people, without a dirty word, but it made people feel hateful.

Ye Qiu was not a taste in his heart, gritted his teeth and said: "Okay, good, four-eyed chicken, it's blocked, I didn't cure you, wait out, wait until I go out, and I'll talk to you slowly when I go out!" ”

"Officer Ye, you just said that there are hundreds of thousands, millions of infected people outside, this is ...... Is this true? When Song Yinyin asked, her voice was already a little trembling.

Ye Qiu asked rhetorically: "Then you calculate, how many people are there in the entire South China?" ”

Song Yinyin said: "Although the number of people in South China can't catch up with the Central Plains and Northeast China, how can there be hundreds of millions of people......

Ye Qiu said: "Then there are hundreds of millions of infected people. ”

"Huh?!"

Not only Song Yinyin, but also Luo Guangcheng, Tang Tian, and Gu Yicheng couldn't help but be shocked.

Ye Qiu snorted lightly: "Don't say anything, you can go out and see the sins you have created later, it is estimated that it will be your lifetime of guilt." ”

Liang Yi suddenly asked at this time: "By the way, I have always had a question I want to ask - has the X virus you researched flowed out?" ”

Luo Guangcheng said: "How can such a deadly and highly secret thing be taken outside? It's just that at the beginning of the experiment, the Huaxia military had a special commissioner to take away the samples. ”

"When?" Liang Yi asked again.

"Three months ago." Luo Guang became enlightened.

3 months ago...... Liang Yi remembered that Wang Ying had told him that the first case of the epidemic was found in Huaxia three months ago, and then transferred to the military university for centralized diagnosis, is it really such a coincidence?

Liang Yi stated all the information he knew about the outbreak of the epidemic.

"Impossible!"

Luo Guangcheng denied Liang Yi's words: "If the infected patient is really found and transferred to the military university, then why don't I know?" Who has the authority of my research team in the whole South China City? Sir Liang, who did you listen to about this? If an infected person does appear, it proves that the experiment has been compromised, whether unintentional or malicious, and the project has long been stopped by the government. ”

"Didn't the government tell you to stop?" Liang Yi frowned.

Luo Chengguang shook his head and said: "The government only told us that a very serious epidemic broke out in Huaxia and told us to wait for rescue, that's all." ”

"What about the mutated spiders on the third floor and the corpses of scientific researchers? You don't know either? Liang Yi asked again.

Luo Chengguang shook his head and said: "The third floor is the insect laboratory, we used the X virus to breed insects, but the insects were too poor in experimentation, and they died in batches after ingesting the virus, so we changed the experimental subjects to rodents and mammals." ”

Ye Qiu suddenly guessed: "I see that you are not only using rodents and mammals, you are also engaged in human experiments!" That's why the body of your colleague will be found on the third floor...... If that's the case, then it all makes sense! ”

"Officer Ye, your guess is too ridiculous, isn't it?" Even Song Yinyin couldn't help but look back and roll her eyes at Ye Qiu, "We are not so cruel, first experimented on mice and extracted vaccines, and then experimented on dogs and orangutans, and ah, there are 13 people in our team, except for 4 of us, the other 9 have families in South China City, and when they heard that the epidemic was serious, they all went home, but they have never come back since they went home...... But I can guarantee that none of our colleagues will die on the G3 floor, the G2 floor is a top secret level, and there is no possibility that there will be no one! ”

"What's going on? We clearly saw people in military uniforms and white coats, and their corpses were full of parasitic insects, huh...... Now that I think about it, my scalp is numb......" Ye Qiu said with a hard grip on his head.

Gu Yicheng said at this time: "Maybe it was the experts who brought support from the outside by the army, but they unfortunately encountered a mutated spider and were killed. ”

Liang Yi always felt that Gu Yicheng's explanation could not be a lie, but there must be perfunctory and far-fetched, he must have something to hide from himself, maybe even Luo Guangcheng was kept in the dark.

If Liang Yi could look at Gu Yicheng's eyes face to face, then he would be able to determine if Gu Yicheng was hiding something, but it was too far away now......

……

"Alright, it's time to rest, then we're going to climb to the first floor, there will be infected, giant berserkers, and mutants with traits will appear, pay attention to your steps and keep absolutely quiet."

Liang Yi's reminder made everyone have to face it with twelve points of spirit.

Starting from the first floor, most of the ventilation system of the scientific research building is composed of central air conditioning, and the pipes are different from the square of G 1, and the circular pipes are used, so that the space is obviously much narrower.

"Sir Liang, there's a cobweb in the ventilation duct." Ye Qiu reminded in the back.

Liang Yi pulled out his sword, not daring to take it lightly.

After experiencing the G 3 spider's nest, even a spider's web can cause them nervousness.

In this way, everyone was silent, and after climbing a connecting ladder with a drop of 3m, the first floor was reached.

"Roar, roar, roar!"

"Da Da Da!"

The loitering and roaring of the infected!

Everyone's nerves were tense to the extreme!

PM20:11, the night is dark, and there are no fingers in the pipe.

"Attention, we're going to go through the first air outlet."

Liang Yichong gestured a finger to several people behind him, opened his red pupils for night vision, and slowly crawled forward.

The ventilation system above the ground level is not as complicated as the basement, and the ladders are placed back and right, and there are not so many roundabouts - you can see that the ladder leading to the ventilation pipe on the second floor is at the end of a straight pipe, and the distance is about 100m, which is not long, but there will be an air outlet every 5m, and each air outlet is about 1m long, which means that if you want to climb through this road, you must pass through 30 vents......

It's bound to be a long and thrilling process, as the hallways under the vents happen to be the most infected...... No one can guarantee that they will not raise their heads, and no one can guarantee that there will be no accidents.

Liang Yi had to pay attention to every air outlet for a while, and only after the infected person had passed before beckoning a few people behind him to climb forward.

It's a good thing to be timid, at least the action is delicate, Luo Guangcheng and the others were frightened when they saw the infected person for the first time, and when they climbed through the air outlet, they didn't dare to take a breath even if their faces were red.

In this way, the group climbed at a rapid pace, and before they knew it, they passed 40 minutes, but only 70% of the distance was covered.

P.m. 20:54, there are still 3 hours until 12 midnight, counting the 1 hour on the return trip, there are still 2 hours left to escape, but at the current crawling speed, it is still unknown whether the exit can be found, not to mention the most dangerous descent will take time......

Liang Yi and Ye Qiu could only be in a hurry, in this case, they didn't dare to open their mouths to urge, especially Luo Guangcheng, who was crawling in front, three steps and one breath, ten steps and one stop, slowing down the overall forward rhythm!

Suddenly!

Luo Guangcheng stood still on his stomach when he passed through an air supply outlet!

His mouth was open, his eyes were almost out of his sockets, and his face was frightened to iron blue...... "Ha, ha, ha......" He gulped as if he had a sudden asthma!

Liang Yi turned back to the air supply outlet and glanced at the corridor scene - a giant monster had wandered under the air supply at some point, its body was already tall, and its head was almost on top of the air supply outlet, and at this moment it was raising its head and looking at Luo Guangcheng without blinking.

Ghostly eyes, filthy and condensed facial features, sallow and sharp teeth with saliva, like a hellish Shura...... Why didn't you scare this old man to death?

"Poof!"

Liang Yi didn't think much about it, and a sword stabbed into the giant monster's head!

"Roar!"

The monster wailed, but still had the strength to struggle!

Liang Yi used another force, and the three-foot Qingfeng stabbed all of them into the monster's body, and then twisted it fiercely, "Poof!" When he pulled it out, he was hot-blooded and poured Luo Chengguang's face!

"Ahhh

Luo Chengguang covered his face and collapsed and shouted, Liang Yi quickly covered his mouth, quickly pulled through the vent, and shouted at the first few people behind:

"Climb fast!"

Use a lighter to burn the tortoise's buttocks, and the tortoise can walk like a fly!
