Five months later, in the early morning of the last day of the hell training, a sturdy young man was swimming at a high speed in a swimming pool in the three-dimensional space training ground, and this young man was Jin Yan.

As Jin Yan's hand touched the pool wall, a mechanical voice sounded: "54 seconds 21." ”

Jin Yan left the pool with both hands holding on to the tiles on the edge of the pool.

At 1.8 meters tall, the muscles of the whole body are not exaggeratedly bulging, but on the contrary, they are full of explosive beauty, and the six obvious abdominal muscles seem to declare the strength that Jin Yan has. The skin looked fairer under the sun, Jin Yan took off his swimming cap, brushed his slightly long hair with both hands, and said with a smile: "Old Five, I said that your 100-meter freestyle speed is too slow, and you still don't accept it, are you still taking it this time?" ”

"! You're two seconds and a little bit faster than me, proud of what? Today I was in a bad state. Wei Jiaming, who was also wearing only a pair of swim trunks with Jin Yan, retorted while lying on the chair.

Now Wei Jiaming's 1.85 meter tall skin is getting closer and closer to bronze, with clean and neat short hair, the eyes under the thick eyebrows occasionally reveal a hint of ruthlessness, and the thin lips always purse when they don't speak, giving people a sense of perseverance. Although the muscles in his body are not as perfect as Jin Yan's, the muscle mass seems to be larger than Jin Yan's.

"Today is the last day of training." Jin Yan casually lay on the chair and drank a sip of freshly squeezed orange juice and said slowly.

"What? Fourth brother, are you still a little reluctant? Wei Jiaming quipped.

Jin Yan rolled his eyes, it has been since he started training at the end of October to the end of April, and in the past half a year, Jin Yan has hardly slept enough, and he is desperately squeezing the potential of his body every moment of every day. Now I just want to escape from this place and never come back, how can I still have the mood of reluctance?

Jin Yan's mind went back to the five months of crazy training.

Wearing weights and doing push-ups to achieve blackening in front of your eyes no less than 20 times, lifting weights until your arms don't even have the strength to lift up chopsticks, and running until your legs are weak and you can't stand at all. Armed swimming in a river where the ice has just melted, freezing until your lips have turned purple and black. Too much hard work has already honed Jin Yan to be more restrained.

"Did you two swim naked so early to get your muscles burned?" Cheng Shixin's silver bell-like voice sounded, pulling Jin Yan back to his thoughts.

"Here it is, Xin'er." Wei Jiaming called Cheng Shixin a few months ago, and was pulled out by Cheng Shixin to practice alone, I don't know how many times, but I still have no memory, until Cheng Shixin was impressed by Wei Jiaming's dead face and stopped paying attention to him calling himself 'Xin'er'.

This is also something that Wei Jiaming often bragged to Jin Yan, what "my Xin'er" or "Xin'er is really beautiful today" and something like that, Jin Yan was still covered with goosebumps at first, and now he is numb.

"Didn't you say that you don't train on this last day, it's already a habit to wake up in the morning, and you can swim for a while when you have nothing to do." Jin Yan didn't look at Cheng Shixin, looked at the pool and said.

"Well, it's not training, but I still have something to say, I should have said it yesterday, but I forgot it yesterday."

Jin Yan sweated a little when she heard Cheng Shixin's slightly embarrassed tone, but said plainly on the surface: "What's the matter?" ”

"Let's talk about it when Shen Hao comes." Cheng Shixin found a recliner and sat down, and said with a smile.

At present, there are only three people training under Cheng Shixin, and Shen Jun was eliminated from the ordinary army by Cheng Shixin two months ago because he couldn't stand such high-intensity training.

"Then my fourth brother and I should change our clothes first, we can't keep walking around in swimming trunks." After saying that, Wei Jiaming took Jin Yan to the changing room.

Wei Jiaming, who was changing his clothes in the changing room, asked Jin Yan, who was dressed in a black suit, "Fourth brother, Xin'er, what do you want to say?" ”

"It's nothing more than the current situation outside, after all, we stayed in the three-dimensional space for half a year and then went out once. Or maybe it's about blood. ”

The two brothers walked out of the locker room while chatting, and when they walked to the edge of the pool, they found that Shen Hao was already sitting on the deck chair, Jin Yan smiled and said hello to Shen Hao and found a deck chair to sit down.

Cheng Shixin coughed twice and still lay on the recliner and said: "Now I will explain to you what the outside world has become, and tomorrow the three of you will still come to the entrance of this three-dimensional space on time at half past five, ready to accept something that you can't imagine." ”

Hearing Cheng Shixin's words, Jin Yan knew in her heart that tomorrow would be the time to reveal the secret of blood.

"Nowadays, ordinary troops have long been unable to carry out operations to search for refugees, because general-level zombies are no longer the highest combat power of zombies. You know the level of zombies, right? ”

Cheng Shixin looked at the three people who nodded and continued: "You know the level of zombies, then I will bother to explain the level division to you, now the people running rampant outside the base are all king-level zombies, and the strength of the king-level should be about the same as my real strength." Take a good look at me. ”

Cheng Shixin disappeared on the recliner with a 'bang', Jin Yan's pupils shrank sharply, not so much disappearing, but rather an illusion that had far exceeded the speed that human beings could reach.

Looking at Cheng Shixin, who was sitting next to him for just a second, with a sweet smile on her face, Jin Yan narrowed her eyes slightly and said, "Soon, it seems that it can't be captured by the naked eye." ”

Wei Jiaming's mouth was so big that his speech became unfavorable: "This... This.."

Cheng Shixin showed her true strength for the first time, which shocked all three of them.

Jin Yan shook his head and smiled bitterly: "Are king-level zombies so terrifying? This is indeed not a height that can be reached by human beings. ”

Cheng Shixin nodded and said: "At present, the most lethal weapons that humans can create can only barely deal with zombies below the third level of the king, but the cost of these weapons is too high to be popularized to ordinary troops, and the guns are still a little useful for the agile king level 1 zombies, and it is a little powerless to deal with the power type king level 1 zombies." ”

"Wait, agile? Strength? Jin Yan asked suspiciously: "I was picked up by the army searching for refugees half a year ago, and the officer also mentioned this word when I met a general-level zombie on the way back to the base, is there only one way for zombies to develop?" ”

"There are also balanced and special types, agile zombies are faster but relatively weaker in strength, while power zombies are weaker in speed, balanced is a combination of speed and strength, there are no outstanding advantages and no shortcomings, and the special type."

Cheng Shixin looked up at the sky and paused for a moment and continued: "There are two types of special types, one is a zombie with human intelligence but not a human being, and the other is mutated into an inexplicable thing because of the climate, environment and other reasons, and you may be able to see it in the future." Regardless of the special type, it is extremely troublesome. ”

Inexplicable something? What's that? Jin Yan's heart was full of doubts, but she didn't ask, because Cheng Shixin must have never seen it, so she said 'inexplicable things'.

"Xin'er, since zombies have a hierarchy, how did they evolve?" Wei Jiaming's tone was full of tenderness and said to Cheng Shixin.

", do you still want to be beaten?" Cheng Shixin rolled her eyes and said: "Zombies below the king level will automatically evolve, and the fastest way for zombies above the king level to evolve is to eat the same kind of people if they want to evolve." Of course, this is also the fastest way for zombies below the king level. ”

"Eating the same kind?" Wei Jiaming's brain made up the picture of zombies eating zombies, and his stomach churned, and the rotten meat was also a zombie that could go down to his mouth.

Cheng Shixin pointed to his neck and said, "The power essence of zombies mainly exists in the cervical vertebrae, and then the head. ”

Jin Yan was shocked in his heart, no wonder when he observed the zombie fights at Zhao Xingyi's house, he was biting in the direction of the neck or head, and the low-level zombies might only retain this primitive evolutionary instinct!

Cheng Shixin continued: "And human flesh and blood are a catalyst for zombies to quickly stimulate the energy in the cervical spine, in fact, their kind of creatures can eat anything, and flowers and plants can also satisfy their hunger. Zombies can starve more than humans, and it is not a big deal for them not to eat for two weeks, and they will not die of thirst without drinking water for a week, and it is scientifically speculated that they may all live twice as long as humans. ”

"How did they appear? Or why is the world the way it is? Although Jin Yan didn't have much expectation for Cheng Shixin to answer this question, he still asked.

Cheng Shixin shrugged her shoulders and spread out her hands, and said helplessly: "The corpse liquid in the spiral tube is leaking. ”

Jin Yan was amused by Cheng Shixin's words and said: "Haha, this reason is really easy to use, and it is really cliché." ”

Cheng Shixin also smiled, and the two small dimples fascinated Wei Jiaming.

"I don't think the real reason will be announced to the world, there is only one reason to fool the 'kind' people." Although Jin Yan smiled, his eyes were cold and there was no trace of smile.

Jin Yan understood that he and Wei Jiaming were just soldiers, and soldiers couldn't touch anything secret at all, maybe everything depended on Zhao Xingyi.

"Is there anything else you'd like to ask?" Cheng Shixin's eyes swept over the three of them and asked.

"I have it, I have it, excuse me.." Wei Jiaming raised his hands and looked excited.

"I refuse to answer your question!" Cheng Shixin snorted and looked at Jin Yan and Shen Hao.

"If we don't train today, can we get out of this three-dimensional space?" Jin Yan turned his head to look at Wei Jiaming, who looked dejected, and asked with a smile.

"Of course, if you don't want to leave today, I'll take you away, this place will be cleaned up in a while and then welcome the recruits in a few days." Cheng Shixin stood up with a smile and waved her hand and continued: "Let's go now, you go back and pack your things first, I'll wait for you at the exit of the three-dimensional space." ”
