Lei He and Luo Cheng sat side by side on the hatch of the heavy mecha, both shirtless, sweating and panting, covered in black engine oil, like two young auto mechanics.

The two of them were busy for more than an hour, the electronic system and servo system of the heavy attack mecha were complex and sophisticated, and the two of them had to check one line at a time, and thousands of interfaces, none of which could be wrong. Luo Cheng didn't understand these things, he could only follow Lei He's instructions to work. Lei He rarely had a helper, and immediately called Luo Cheng to death as cheap labor, as a cow and a horse.

Lei He always pretended to be too busy to pull away, holding a wrench in one hand and a multimeter in the other, and biting the tape in his mouth, he got out of the cabin and shouted at Luo Cheng, the latter didn't know why, so he had to honestly move this and that, carrying dozens of kilograms of large bearings on his shoulders, climbing onto the two-story mecha, his shoulders were bruised.

Normally, when Reich completes these tasks alone, it takes at least two hours, and with an extra helper, they reduce the time by more than half.

For the first time, Luo Cheng knew that overhauling the heavy attack mecha was such a heavy job, not much easier than driving the mecha, Lei He had to drive and maintain, from the driver to the ground staff, one person was all-inclusive, and he could handle it in an orderly manner without making mistakes.

It was hard for Luo Cheng to imagine that this kind of work had to be repeated every day, no wonder he usually didn't see the shadow of this person, he probably spent most of his time in the warehouse, with machinery and tools all day long.

He suddenly understood why Reich was a good drinker...... This person is too tired and too heavy to live, and if a person like him doesn't seize the opportunity to anesthetize himself, I'm afraid he will directly fall tired on the mecha, right?

In a way, Lei He and Luo Cheng are two completely opposite people, Luo Cheng is a Chinese sniper, who lives a rigorous and regular life, is serious and dull, has the carefulness and caution unique to Asians, and even eats and sleeps at the right time. But Rech was a young Russian pilot, and as a Slav, his life was nothing more than drinking, and he was in the company of cold heavy machinery, so his life was unbridled and unbridled.

"How many are you today?" Rech leaned against the hatch and took a long sip of water.

"Today, February 12th." Luo Cheng replied, "Can't you even remember what day it is?" ”

"It's only you who remember it clearly." Rehe smiled and shook his head, "In this world, what's the point of remembering what day it is?" ”

"Of course it makes sense." Luo Cheng replied, "Recording time is one of the characteristics of human beings, our civilization and history are recorded by time, remembering what day it is, can prevent us from falling into madness." ”

"Today is the twelfth, then tomorrow is the thirteenth, and the day after tomorrow is the fourteenth." Rech muttered, "The fourteenth is Valentine's Day, right?" ”

Luo Cheng nodded.

Rech scoffed, "Is there still Valentine's Day in the safe zone?" ”

Luo Cheng thought for a moment, "Maybe." ”

Lei He poked Luo Cheng's waist and smiled a little narrowly, "Hey, zero distance, is there a girl in the academy who has taken a fancy to you?" Or do you have a crush on any girl? ”

Luo Cheng turned his head and glanced at him, according to the previous situation, Ling Yuan, who has always been known for his unsmiling and seriousness, ignores this kind of problem, if he is in a good mood, he may also reward you.

But today Luo Cheng didn't kick Lei He down, he sat on the mecha and was silent for a few seconds.

"I didn't think about these issues."

"I think there should be a lot of girls in the safe zone who like you." Rech said, "I don't smoke or drink, and I'm very powerful, and I seem to be reliable, in this apocalyptic world, if you want to find a man, is there a better fit than you?" ”

Speaking of Luo Cheng's womanhood, there is almost zero, he rarely has contact with the opposite sex, the last girl who chatted with him was the European girl who died tragically under the claws of the red eye, now in retrospect, that girl should like Luo Cheng a lot, she will take the initiative to talk to Luo Cheng, but unfortunately this girl was dragged away by the invading red eyes before she could say anything.

The relationship between the remaining opposite sex in the safe zone and Luo Cheng is only to nod their heads when they meet.

"I'm not a good fit." Luo Cheng shook his head, "I've been alone since I was a child, and I'm used to being alone. ”

The vast majority of people in the safe zone are lonely, such as Lu Xun and Lemon, who have no other relatives in the safe zone, and can only rely on their comrades, and it is very rare for brothers and sisters like Reich and Belle to be related by blood. In the previous academy, there were only two pairs of brothers and sisters, one was Lei He and Belle, and the other was Zhao Gao and Zhao Mu.

Now there is only one couple left.

In this era, it is an unimaginable luxury to have relatives alive.

"Has it always been a person?" Rech asked.

Luo Cheng was silent for a moment, "When I was very young, I had a sister. ”

"Ever?"

"Then she died." Luo Cheng continued, "She committed suicide and jumped from the building. ”

Rech was taken aback.

"She is two years older than me and is my own sister, so she takes very good care of me, and she also took my name...... When I was a child, I was thin and didn't talk much, so I was often bullied, and my sister would stand up and help me get rid of those people. Luo Cheng said softly, "She's a girl, but she's very powerful, and no one else can beat her...... She said to me, Luo Cheng, you have to grow up quickly, she protected me when I was a child, and I will protect her when I grow up. ”

Rech did not speak.

But she couldn't wait for that day...... Before I could grow up, she died. Luo Cheng took a sip of water, "In the experiments of adults, she was tortured, mentally disordered, and completely crazy, when she was crazy, she didn't know anyone, she bit people when she saw them, smashed things frantically, and hit doors and walls...... The adults tied her up and threw her into a confinement cell, where she was given a large amount of sedatives every day and was not allowed to come out. ”

"Sometimes I sneak out to find her, and I talk to her outside the door of the confinement room, and my sister is happy when she hears my voice, and she is in normal spirits when she talks to me." Luo Cheng said, "Every night I sneak out to find her, and then go back to my room before 3 a.m., when I ...... I think my sister will always be in that room, and I can go to her every day, and when I'm older, I'll be able to let her out. ”

Luo Cheng's voice suddenly lowered, suppressing the pain that worried his heart.

"Later...... One day at noon, we were in the courtyard to get windy, and suddenly we heard that someone had fallen from the upper floor and died...... I followed the others and ran over to watch, squeezed into the crowd, and saw my sister lying on her back on the grass, staring blankly at the sky with her eyes open, her mouth open, blood spilling out from under her body. Luo Cheng said, "She was wearing a white dress, and the skirt was soaked with blood. ”

Luo Cheng's voice was trembling, he had never told anyone about it, this was the deepest nightmare in his heart, it had made him wake up again and again in the middle of the night, and his sister's young body with broken limbs lingered in front of his eyes.

Lei He never knew that Luo Cheng had a crazy sister.

"The adults rushed up and chased us away, put my sister's body in a bag and dragged it away." "Later, I heard from the adults that it was because a nurse forgot to lock the door of the confinement room that allowed the mad girl to escape, and she climbed to the roof while everyone was having lunch...... Jumped from above. ”

Luo Cheng's voice disappeared, and he sat on the mecha in a daze, his eyes blank, as if he had just woken up from a nightmare.
