Lu Wu turned around, only to find that the master reminded him a little too late. However, this may be due to the terrain - there is a big road outside, and even if you are a master, when someone else shows a definite movement, the other party will come to a closer position.

It was four or five o'clock in the afternoon. For the city of W, the sun has not yet set at this time. Although the sun has long since lost its midday glow, the light is very good.

The two people standing in front of Lu Wu were not strangers. But neither of the two was what he intended to see.

The three of them looked at each other silently, and for a moment the air seemed to freeze.

"What do I think I'm up to...... So that's it?" Just when Lu Wu was a little at a loss, the other party had already walked to the edge of the exoskeleton armor. Of course, although its design idea is a reference to another world, it is made on Earth, and all the materials are ready-made on Earth. Or at least it seems. If a completely unwitting stranger saw the machine, he would never think of the word "alien", but rather that it was a model built by a robot enthusiast himself. After all, it looks too rough and a little too rudimentary now.

You know, now robotics is not a black technology for a long time. On the Internet, even those robots that are difficult to judge with the naked eye have appeared. Compared to those delicate things that are no different from humans, the things that Lu Wu is building are really not worth mentioning. That's just the level of an amateur. At least it seems.

"Zhang Yao, what are you doing here?" Lu Wu was really a little embarrassed. It was an uninvited guest he hadn't expected at all, and he didn't even know what attitude to use for a moment.

"I got to W City. My sister replied. "One copy. She said the last two words loudly. "So come and meet you...... They said that since you are here, you can take care of me. ”

It should be noted that Lu Wu's sister does not have the surname Lu, because according to the traditional Chinese marriage tradition, the children are all from the father's surname. In those days, although there was no hard and fast law to protect such provisions, in fact it was a deep-rooted custom.

Lu Wu wanted to speak, but he didn't know where to start. Generally speaking, the relationship between siblings is more harmonious than that of brothers, but there are exceptions to everything. Of course, you could say that it has something to do with the specific family situation.

Lu Wu's sister touched the robot with her hand (it looked like a robot). As mentioned earlier, even if you don't care about the cables that look messy, the most conspicuous skeletons in front of it look a little rough. There are still some traces of welding on it.

"But it doesn't seem to be a good deal. She looked at the robot with an indescribable expression on her face. "I really didn't know you were so unprofessional. ”

"Not doing business?" Lu Wu wanted to say in his heart what my business is, and it is estimated that no one dares to believe me when I say it, but there is no way to say it. "Going to university, but now it's long past the college entrance examination......"

Even idiots know that China's college entrance examination is summer – not to mention winter, even spring is not far away!

"I've already passed the test. The little girl raised her chin haughtily. Although it is not a 985211 college, it does not mean that it really can't be done, in fact, among the non-985211 colleges, the overall level may not be as good, but some professional levels are very high, even if it is called the first in the country. "I've been here for half a year now. ”

"That ......" Lu Wu slowly came back to his senses, and the other party had already come to W City, but he didn't come to him at all. Looking at the appearance of the uncle next to her, he could probably guess that in fact, the other party came to see him and belonged to the type of reluctance. In other words, it was precisely because the uncle came over that she had to come to see Lu Wu. Otherwise, two people will still live in the same city as before, and they will not get along with each other. Lu Wu didn't even know that his sister was also admitted here.

"The ......"

"Although you don't have a proper job, but seeing that you have the leisure to play with this kind of thing, I guess you have a good life. Zhang Yao looked up at the house where Lu Wu lived. As mentioned earlier, this is a fairly common illegal building in the suburban junction of W City, with a warehouse below and a residence above. As with all houses of this type, the end result of this "non-professional remodeling" is that the warehouse below is not large, and the dwelling above is not large. In short, it's the kind of house that looks like a "good bargain". It may be a good value for money, but it can only discuss the issue of cost performance.

At this moment, the door of the warehouse on the first floor (it was first used as a fabric warehouse, then as a crystal ore warehouse by Lu Wu, and then it has been vacant) is open, and the warehouse is relatively empty, with an electric light lit in the middle, and you can see some parts piled up on the ground, and some boxes with certain accessories on the side.

On the whole, there is no doubt that Lu Wu chose this place as a residence because of its high quality and low price, and at the same time it can meet the needs of "not doing business". This shows that he should spend a large part of his time on these "unorthodox jobs".

The fact that a person is qualified to waste his time and energy on these things shows in itself that he has mixed well, at least he has solved the problem of food and clothing, and does not have to worry about his own survival. Of course, it can be seen from this inexpensive accommodation (Ren Jian had already told them that this is a rented house) that a good mix is just "good". Anything rich or rich or anything like that doesn't matter at all.

Combined with what he saw and heard in Ren Jian before, it is very in line with his previous imagination. It's almost a small boat that is still playing that kind of trick to win the trust of customers, struggling in the waves of the commercial sea. In fact, this is not even a "boat", probably only the grade of a canoe.

In this case, I am not seriously engaged in business, but on the contrary, I am playing with these meaningless robot manufacturing in addition to satisfying personal hobbies, and it is indeed very appropriate to describe it as "not doing business".

"In that case, I won't talk much. "The gesture of being a sister is not so much a sister as a queen. "Here's my business card, I'm leaving. ”

It stands to reason that she should go upstairs to see Lu Wu's current living status. But what she saw made her feel that it was no longer necessary. Anyway, her real task was to find out how this brother was doing now—the kind that didn't need to be very detailed. So she thought it was enough, even if she went upstairs, she just saw the inevitable chaos and squalor of a man's bachelor dormitory. In that case, what reason is there to go up?

She turned to leave, leaving Lu Wuyi unable to come back to her senses.

……

"Hey, A-Yao, that's too ...... Isn't it a little cold? Why does he say it's your brother?"

"What about my brother? Anyway, he said last time that he would never come home again. ”

"That's angry talk, angry talk! angry talk can't be taken seriously!"

"Anyway, Mom and Dad just let me see how he's doing, and it looks like he's doing well, so that's fine. She snorted. "At least you won't starve to death, and you won't become a vagabond, that's fine. If you look at his residence, there is a house above and a warehouse below, and the house is dozens of square meters...... He still has spare money to play with robots, so what else is there to say? Could it be that he can really turn into a serf and sing and accumulate billions of dollars?"

"Hey, what's the ...... for you Why are you two like this!okay, okay!"

While speaking, the two men were already standing on the street. As mentioned earlier, although it is a suburban junction, but the modern suburban junction has long been different from what it used to be, and it must be said that there are more old houses, more foreign population, and the public security is slightly chaotic, and there is no difference between the city and the city in terms of road traffic, or even better. Without much effort, the girl reached out and stopped a taxi.

"I'm going back to school, uncle, what about you?"

"I'll go back to the hotel, and I'll be back tomorrow...... Anyway, if you have time to contact Lu Wu, what do you say, it's also in a city. ”

……

"Partner, is this your sister?" the master asked in the headphones.

"Half-blooded sister," Lu Wu replied. "I did well in my studies and was calm and smart all the time...... Much better than me. It is the most typical 'other people's child'. He uttered the last sentence in a self-deprecating tone. The current master is quite familiar with the earth, so he can understand all kinds of memes.

Then he picked up the business card and looked at it, it was a business card from the XXX design room, and it looked like she was doing something else besides reading. Lu Wu originally wanted to ask, but found that the other party had already walked away.

"By the way, master, what's going on over there?" was disturbed by her like this, and Lu Wu was in no mood to continue assembling the exoskeleton.

"Very good," said the master. "But you need to be a little more patient. After all, if you want to leverage the development of science and technology in this country, then materials science is the best choice, because materials science is the most difficult science to progress, and it depends on long-term continuous investment to achieve results. And the progress of material technology is slower than that of a snail. But every step of the crawl is equivalent to untying a rope around the necks of designers and researchers - too many designs cannot be realized because of raw material problems. But in any case, we can't suddenly raise China's metal materials to the level of space warship armor, right? In that case, it is estimated that an individual will be able to detect that something is wrong. We have to take it one step at a time, at least to make technological progress look well documented, not in the air. It has to be said that the country is very sensitive in this regard, and as soon as the new alloy is made, they immediately perceive it. What about a lot of orders from various state units!"
