After Sun Fatzi left, Zhao Hao pondered on the kang.

Zhao Shizhen and Zhang Jian, who were waiting on the side, watched him draw a sketch like a stove, and there was a boom-like thing next to him.

Of course, a soul painter like Zhao Gongzi. He doesn't explain it to you, and you can't figure out what he's drawing.

"Uncle, what is this?" Zhao Shizhen finally couldn't help but ask.

"Guess what?" Zhao Hao looked at his sketch for a while, and then looked at the two future genius mechanical experts in front of him, and was a little undecided.

"Could it be ......" When Zhao Hao ordered the fat man, Zhao Shizhen was next to him, how brilliant was he? I immediately thought of what my uncle said during my trip to Xishan last year.

"A machine that automatically lifts water?"

"Clever." Zhao Hao gave a thumbs up.

Yes, he painted the Newcomen steam engine. This is also the limit that can be achieved at the current level of technology...... As for the watt type, don't even think about it until you don't have a steam boring machine.

The principle of Newco door machine is very simple, and the manufacturing process is not as demanding as the bird gun.

But Zhao Hao's hands-on ability is about equal to zero, and he can't make it if he kills him.

Of course, when the two mechanical masters in front of them mature, it is estimated that it will be easy to manufacture.

But those were two people ten or twenty years later.

Zhao Hao's original plan was to teach them physics and mathematics at the junior high school level. After they learn the scientific manufacturing method, let the two of them challenge the Newcole door machine.

But who would have thought that the mother of the eldest princess would fall from the sky? This allowed him to reach into the mine at least two years ahead of schedule.

The schedule for manufacturing automatic water lifters will naturally be advanced......

But now, the level of these two people can only be regarded as handicraft enthusiasts, can they take on this glorious and difficult task?

"Uncle, tell me about it, I'll make it for you!"

Zhao Shizhen was gearing up and couldn't wait to urge. After all, creating this thing was one of his three major goals in life.

Zhang Jian also showed an expectant gaze. He has been familiar with Zhao Shizhen in the past few days, and he has already heard the master's eldest nephew describe that kind of magical automatic water lifting device.

"Let's just be an amateur." Zhao Haoxin said that if Zhao Shizhen didn't make this thing, he wouldn't be idle. Instead of letting him pull Zhang Jian to think about making a gun, it is better to let the two of them focus on this first.

Well, Ben Gongzi is peace-loving. It's just the kind of ...... that comes with a twelve-pounder cannon

He took the sketch and explained to the two of them the principle of the Newco door machine.

"The lower one is the boiler, which is connected to the cylinder at the top, and there is a piston on the cylinder, and the piston is connected to the moving lever at the top...... When the boiler is heated, the steam in the cylinder expands, and the piston is pushed up...... Spray water into the cylinder to condense the steam, and the atmospheric pressure pushes the piston down...... In this way, the cylinder is constantly inflated and condensed, and the piston will drive the lever to move up and down to pump the water out of the mine......"

Zhao Hao said that he was the first to speak, and no one could see it, but he couldn't do anything.

The two listened intently. While Zhao Shizhen was sketching, he asked Zhao Hao about the details of each part.

"Yes, there's an intake valve here, and this is a water injection valve......"

Under Zhao Hao's continuous correction, the sketches drawn by Zhao Shizhen became more and more like that.

Finally, after the seventh draft was formed, the drawings drawn by Zhao Shizhen were almost the same as the Newco door machine that Zhao Hao read from the books.

Zhao Hao slapped the table and said, "That's it!" ”

I didn't praise the genius anymore this time......

After all, with him, it is not difficult to draw drawings. The hard thing is whether you can build this thing according to the drawings. After it is built, it has to be able to work as expected, so it is really awesome.

I'd better save that sentence and wait until the time comes.

Zhao Shizhen has already ignited a strong fighting spirit, and through this discussion with his uncle, he has understood the principle of this 'automatic water lifter'.

He couldn't wait to try out this magical device that could make the lever reciprocate by boiling water.

Although Zhang Jian barely spoke, his eyes flashed with excitement.

His understanding of mechanical devices is much stronger than that of Zhao Shizhen, who focuses on weapons, and he can vaguely imagine how much change this device will bring to the world if this device can become a reality......

Compared with this kind of great thing, what is it if you can't pass the exam in a lifetime?

~~

When the two geniuses left excitedly with the drawings in their hands, Zhao Hao glanced at the father who was still tossing and turning pancakes on the kang.

"Father, did you quarrel?" Zhao Hao couldn't help but feel a little strange.

Zhao Erye's sleep quality is superb. Usually as long as the head touches the pillow, there will be a snoring sound within ten breaths, and Zhao Hao and they can't make noise no matter how loud they talk.

"Nope." Zhao Shouzheng snorted, turned over again, and faced the wall.

'Doesn't seem to have anything to tell me. ’

Seeing this, Zhao Hao blew out the lights. He was tired enough this night, and he didn't have the energy to care about his father's emotional problems.

"Could it be because I can't see my mother for a month, and I can't bear to ......" Before going to bed, a ridiculous thought rose in Zhao Hao's heart.

He couldn't help but secretly say, if my mother knew that the retreat was my idea, I was afraid that she would complain about me.

Then Zhao Hao fell asleep.

Well, his sleeping nature follows his father.

~~

As soon as it was dawn, Zhao Hao was woken up by the sound of Suosuo's rummaging, and he thought that the family had recruited thieves again.

I just wanted to shout at the top of my voice, only to find out that it was my dad who was rummaging through boxes and cabinets looking for clothes.

I saw that he put more than a dozen robes of different colors, textures, and styles on half of the kang.

Zhao Hao knew what Daddy was going to do.

The beauty has an appointment. Oh no, I'm going on a date with my mother......

Otherwise, Second Master Zhao wouldn't have picked out his own clothes, he would wear whatever Fang Wen had prepared.

The old love was rekindled, and it was very fast. ’

Zhao Hao couldn't help but be secretly happy in his heart.

He likes to hear about it. After all, the mother is the strongest backing for herself, of course, you must have the consciousness of 'taking the mother's likes and dislikes, for the likes and dislikes'.

"It's a pity, my mother is embarrassed to talk to me, otherwise I would have helped her get Zhao Erye ten times eight times...... Zhao Hao sighed secretly, feeling very guilty that he couldn't help his mother too much.

'Maybe people like to look for the feeling of first love......

Zhao Hao explained to himself, then turned over and continued to sleep, so as not to embarrass his father.

~~

By the time he woke up, it was already three poles in the sun, and his father had long since disappeared.

Hearing that there was movement inside, Zhang Jian and Yu Shensi, who had been waiting outside for a long time, hurriedly came in with basins, toothbrushes, combs, cotton towels and other things.

In addition to not being very skillful in his movements, his hands and feet are not much slower than those of the eunuchs of the Qianqing Palace.

While brushing his teeth, Zhao Hao listened to Yu Shensi's report:

"Shizu said that he will accompany Her Royal Highness the eldest princess today to visit the homeless people in Baiyun Temple, and it is estimated that he will not come back early. So that the master doesn't have to wait for him to celebrate the holiday. ”

"What festival?" Zhao Hao was stunned.

"Shangyuan Festival!" In the outer room, Li Mingyue's voice as crisp as a yellow warbler sounded. "Big brother, let's go to the temple fair!"

"Oh, Shangyuan Festival."

Zhao Hao suddenly said in his heart, no wonder, it turned out that the second child went to celebrate Valentine's Day......

He was still young, so he didn't dare to think about it anymore.
