"You... You repeat. The old man also couldn't believe how such a young girl could understand so much.

"Oh." Ma Qingqing repeated what he had just said, looking very relaxed and effortless.

"Girl, someone taught you this before?" The old man confirmed this time that the girl in front of him was by no means talking nonsense, and every detail she said was explained by herself.

"No, I don't have time to learn such boring stuff." Ma Qingqing replied.

"None? How can it be. The old man had an unbelievable look on his face, thinking that someone must have taught Ma Qingqing to have such an understanding of mecha manufacturing, and it is impossible for ordinary people to have such a high consciousness.

But the old man found that he was wrong, Ma Qingqing had never learned this knowledge, she had just learned it once and remembered it.

"yes, what's wrong old man." Seeing the old man's expression, Ma Qingqing thought that he was talking too much, and asked stupidly. She didn't know how strong the old man's inner shock was at this time.

"God, decades have passed, and you have finally favored me once." The old man was a little excited, a bloodless old face, a little red at this time, he hadn't been so excited for a long time as he was today.

"Huh?" Ma Qingqing was a little overwhelmed, and the old man actually began to talk to himself.

"Grandpa, what's going on?" Luo Yun asked Mu Hai on the side, and he couldn't figure out what was wrong with this old man.

"Ah Dragon, he is burdened with a fate that ordinary people cannot bear, and he wants to change all this. However, he has some stumbling blocks, but now that he sees hope, do you think he can not be excited? Mu Hai said seriously, as if he knew the old man's past very well.

"Grandpa, you know him so well?" Luo Yun asked.

"It's not that I understand, it's that everything he went through has something to do with me, and it can be said that I owe him."

"Why can't I understand?" Luo Yun was confused for a while, and he couldn't understand what Mu Hai said.

"This was many years ago, it's complicated, and I'll tell you about it slowly." Mu Hai said meaningfully. It was as if he had thought of something a long time ago, and there was a hint of confusion in his eyes.

"Oh, okay."

At this time, the old man put down the work in his hand, walked in front of Ma Qingqing, put his hands on her shoulders, and looked at Ma Qingqing with his small eyes, as if he was looking at a rare animal, and Ma Qingqing was embarrassed to look at it.

"Grandpa......?"

"Girl, can you promise grandpa one thing? If you promise me, I will fulfill any request you have. The old man said to Ma Qingqing very seriously, Luo Yun on the side was the first time he saw the old man so sincere. From the old man's eyes, Luo Yun saw that it was not only extremely sincere, but also with a hint of expectation.

"Huh? Grandpa, you say, as long as I can do it, I will promise you. It turned out that Wei Long was asking himself for one thing, Ma Qingqing's tense nerves were instantly relaxed, the old man was kind enough to take her in, and he was also very good to her, if he could help anything, he would definitely do his part.

"Don't say yes yet, or listen to me before you decide." An old man who has been alone for decades, every day he is either dealing with machines or robots, and everything is inseparable from machines. For any relationship, he hadn't experienced it for a long time. When he saw that Ma Qingqing was so sincere, he couldn't help but feel a little moved, and there was a trace of tears in his eyes that were imperceptible to others, but they dissipated in an instant.

It is said that a child at the age of innocence must have sincere feelings. At this moment, the old man completely realized it from Ma Qingqing.

"I am very old, and I have no children or relatives. But, more than twenty years ago, I took in an apprentice. His name is Yi Yang, he is a kind-hearted person, he is very sensible, he respects me, and he is also very talented in mecha manufacturing. I have no relatives, and I have always regarded him as my own son. I wanted him to inherit my mantle and have a bond when I grew old, so I passed on to him almost everything I had learned in my life. However, at that time, a great war broke out between the Mecha Alliance and the Blood Alliance, and he and I were involved in it. After the battle, he disappeared, and I have not heard from him for a long time, and I think he is no longer alive. Since then, I have never accepted an apprentice, because I have not met a suitable candidate, and those who want to worship me as a teacher are either evil intentions or have no talent for mecha manufacturing. To this day, I'm still alone. Speaking of this old man's tone, he was a little choked, Luo Yun was also a little emotional when he heard it, he didn't expect the old man to even have a relative, and even the only apprentice had passed away, it can be said that he is now unaccompanied, and he has been counting him down, and he suddenly felt a little guilty.

"It's all my fault, Aaron, it's me who hurt you. If it weren't for me, you wouldn't be where you are. At this time, Mu Hai looked at the old man apologetically and whispered.

"Brother, it's not your fault, everything is fate." The old man let out a long sigh, and actually called Mu Hai his brother, Luo Yun was instantly confused, it seems that the secret between these two old men is not simple.

"Grandpa, so many years have passed, don't think about the past anymore, treat yourself well." When Ma Qingqing heard what happened to the old man, she was very sympathetic to him and said comfortingly.

"Oh, yes, it's time to forget. Because, girl, you appeared. ”

"Me? Grandpa, you don't want to take me as an apprentice, I'm very stupid, I'm good at eating, and I can't do anything else. Ma Qingqing realized the old man's intention at this time, and it turned out that he wanted to accept himself as an apprentice.

"That's what I thought, girl. Actually, you're not stupid at all, at least you're very talented in mecha manufacturing. And your talent is innate, it's just that you haven't really felt it yourself. The old man said softly.

"I" Ma Qingqing hesitated, not knowing how to answer the old man in front of him for a while, his expression was a little uncertain, as if he was thinking about something. The old man seemed to see her thoughts, and said to her:

"I'm not going to force you, girl. I will say this only on a whim, and it is up to you to decide whether you agree or not. ”

"I promise you, grandpa." After some ideological struggle, Ma Qingqing's expression immediately became very firm, as if he had made a very important decision, and he agreed to the old man's request.
