Airtight test! ”

"Checked...... Qualified~"

"Transmission inspection~"

"Checked...... Qualified~"

"Closure...... Prepare for ignition~"

"Sealed complete!"

"Ignition~"

Rumble...... Cracking sound......

Rumble...... Bang, bang, bang...... Boom...... Boom~

Smoke and dust flew and a clear voice sounded from it, creating a stark contrast to it.

"Why did it fail again?"

After a while, the smoke and dust cleared, and the people involved in the test were all "dusty", but no one cared, and they were all checking to see what went wrong.

There were less than ten people in total, all of them were carefully selected and skilled craftsmen, but the leader was a woman. Everyone was not convinced, one is that the woman's identity is extraordinary, and the other is that the woman's skills are superb, a few points higher than all of them.

A few people silently searched for a leak, and they really couldn't figure out what was wrong. At this moment, another voice came—

"It's ...... Failed again? ”

The woman turned around, her dirty face trembled, and she gritted her teeth and turned back. The visitor quickly closed his mouth and looked at it carefully, but he was always more than ten steps away, never approaching, and seemed to be dirty.

"Yaaa~"

A voice came from the bosom of the visitor, and it turned out to be a child, looking at it with his neck stretched, and he didn't know what he was looking at. That's probably why he didn't come closer.

The woman looked back again and saw the child's face tremble, revealing an ugly smile. The child seemed to be taken aback, and quickly shrank back, but secretly turned his head to look, quite unwilling.

"Let's go wash up!"

The person who came frowned and said, "He is here anyway, and no one can take it away, so he will come later." Besides, maybe after a short rest, your mind will be clearer, and it will be easier to find out the reason. ”

"Okay!"

The woman tilted her head and thought about it, it was still really like this, clapped her hands, and gave two more commands before she walked out, and at the same time asked the visitor, "Why does the master have time to come?" ”

"What do you say?"

The person who came said angrily: "Tell me yourself, how long has it been since you went back to see Xiao Xu, and now you are all separated, right?" ”

The person who came, that is, Gongsun Du, was holding Huang Yueying, who is now one year old.

woman, that is, Huang Yueying. Soon after getting married, Huang Yueying became pregnant, and gave birth to a son at the beginning of the following year, Mingxu. Before and after, Zhen Mi gave birth to a son, named Bao; Mi Zhen gave birth to a daughter, named Yue. So far, Gongsun Du has nine children, five sons and four daughters, and he can be regarded as a prosperous heir.

After Gongsun Xusheng was born for half a year, Huang Yueying felt bored and asked Gongsun Du to find something for her to do. It happened that the steam engine was making slow progress, and after thinking about it, Gongsun Du let it get involved.

At the beginning, Huang Yueying only participated in research for a little time every day, but after a few months, after Gongsun Xu was weaned, it changed greatly, and most of the time he was on the side of the research institute. This time, because Huang Yueying hadn't returned for almost half a month, Gongsun Du came to find someone with his child.

Of course, Gongsun Du didn't know it at first, but he only knew it after Zhang Zhi reminded him.

But when he arrived at the place, looking at Huang Yueying, whose face was black, Gongsun swallowed his dissatisfaction again. In the final analysis, Huang Yueying worked so hard, and he was the one who benefited in the end.

"It's just that the principle of this steam engine is very simple, and it has long been figured out, why it still can't be built after so many years?" Gongsun Du had many doubts in his heart.

It stands to reason that there is a "prophet" of Gongsun Du, and something like the steam engine that has long been eliminated should be very simple and easy to get out; However, in fact, it is precisely because this thing has long been obsolete that I have not seen it with my own eyes, but I have only learned a few words and some principles from the book.

Huang Yueying and others, of course, are masters of this era and have extraordinary creativity, but what does the steam engine represent? If the change of an era is so easy to achieve, can it afford such a name?

The limitations of thinking cannot be broken by an advanced theory, otherwise there will be technical barriers.

When she came to the temporary residence, Huang Yueying went to fetch water to wash off the dust on her face, while Gongsun Du instructed her subordinates to prepare hot water.

"Master, this doesn't have to happen, right?"

"Not necessarily? Hmph, I'll go straight home later. Gongsun Du said toughly.

Huang Yueying was silent for a moment, nodded, and did not speak.

Gongsun Du saw that she was low, his heart was soft, and he said, "Have you been away from home for half a month?" Don't you want Xiao Xu, and you don't want to be your husband and sisters? We are a family after all, and you haven't seen anyone for a long time, isn't it good? The most important thing is that Xiao Xu is still young, how can he do without his mother's company? What should I do when I grow up and have a part? ”

Huang Yueying raised her head and looked at Gongsun Du, to be precise, Xiao Xu in his arms, seeing his eyes flashing, his heart was also soft, and he responded: "What the master said is extremely true." After speaking, he lowered his head and washed up.

Seeing this, Gongsun Du secretly shook his head, thought for a while, and said, "Some things can't be rushed, and you can't change them by immersing yourself in them all day. Let's do it, wait for a certain person to go quietly with you, and in the evening, no matter whether you can gain something, you must go back to the house to meet everyone, how about it? ”

"Really?" Huang Yueying raised her head, her face full of surprise.

Gongsun Du nodded, and then said: "It's not that you have to go home and give up research, but after two years of recuperation, the war is about to resume, and X will soon leave home again." ”

Huang Yueying was stunned and said, "That's it, isn't it?" ”

Gongsun Du shook his head and didn't speak, just looked up at the sky.

After Huang Yueying finished washing, she wanted to take Xiao Xu, but Xiao Xu's face was full of timidity, and in the end she could only turn into a sigh. Gongsun Du didn't say anything, but when Huang Yueying was bathing, he muttered to Gongsun Xu for a while, regardless of whether he could understand it or not. Then after Huang Yueying bathed, she stuffed it into Huang Yueying's arms regardless of it, and then the three of them came to the place where they were tested before.

Gongsun Du had discovered before that the steam engine he built could not convert heat energy into kinetic energy, so that he finally fried the furnace. But it didn't blow up completely, but the iron plate used to seal it blew away.

"Maybe it should be ......"

Gongsun Du's horizons were much broader, and after watching it for a long time, he finally had some vague thoughts, but he didn't say it, but hid it.

In the evening, Gongsun Du and the three returned home together. When Zhang Zhi and the others saw Huang Yueying, they couldn't say anything about complaining, but just held hands and said intimate words.

After dinner, the family chatted in the backyard.

When he was about to disperse, Zhang Zhi said: "Master, is it really going to start the war again?" ”

Gongsun Du glanced at Huang Yueying before saying: "Unless there is a prince all the way to unify the world in the end, the tranquility will always be only temporary." ”

When the women heard this, they all fell silent. In the early years, Huang Qing still had the idea of going to war with him, but under the influence of Zhang Zhi, Cai Yan and others over the years, he was much quieter, and only occasionally practiced martial arts in the house.

"In the previous two years, it was actually because the seeds they bought back needed to be planted, and then they reaped a huge harvest, and they all held their breath and wanted to accumulate more strength." Gongsun Du then said again.

Cai Yanxiu frowned slightly, and said, "Shouldn't the old man sell the seeds to them?" ”

"Shouldn't it?"

Gongsun Du shook his head and said: "No matter what, the people are innocent, even if the war is together, there are countless casualties, but those who do not die can eat enough after all, and they will not starve to death." ”

Only then did the women understand Gongsun Du's painstaking efforts.

After that, Huang Yueying stayed in the house, knowing that Gongsun Xu was close to her again, so she occasionally left home to go to the research institute. At this time, Gongsun Du still did not say what he thought. The time gradually came to the early summer, when sweet potatoes and other grains were planted in various places.
