Qin Tian saved Qin Qiong's son, and it was normal for Qin Qiong to come to thank him.

But even if it is a thank-you, there is no need to recognize Qin Tian as a righteous son, unless Qin Qiong likes Qin Tian very much.

There is a big difference between giving thanks and acknowledging a righteous son.

Thanking is just thanks, and there may not be any intersection in the future, but after recognizing the righteous son, the relationship between Qin Tian and Qin Qiong will be very close from then on.

Being able to become the righteous son of the Wing Guogong is definitely something that ordinary people dare not imagine.

The whole scene praised Qin Tianlai more and more, and more people ran to Tang Rong to bless her with good convincing, although Tang Rong was proud, but she did not have any arrogance because she became Qin Qiong's righteous son, and she was still very humble in front of the Tang family.

Tang Xin gritted her teeth with hatred, glared at her maid viciously, turned her head and went back to her room, but at this time, everyone was congratulating Tang Rong, and no one noticed her at all.

After a while, Tang Yu took Qin Tian's hand and came to the front from behind, the two talked and laughed Yan Yan, and at a glance, they knew that Tang Yu was very satisfied with his son-in-law.

Although Tang Rong was a little displeased with Qin Tian in her heart, she was very affectionate at this time, as if the two were really a pair of newlywed Yan'er, envious of others.

And the Liu family next to her was about to go crazy with anger, if it weren't for the Tang family's face, she would not be able to turn around and leave like her own daughter now.

The entire Guining Banquet was very lively, and Qin Tian and Tang Rong were the absolute focus.

Gaoling County.

Li Shimin and a group of civil servants and military generals prepared to leave.

Li Shimin, the king of Qin, personally went out to fight, coupled with the military generals of the eldest grandson, it was not difficult to get the people of Gaoling County to irrigate the land.

These people can fight the world and govern the country, what is a small Gaoling County?

It's just that when they left, there was also a problem that was difficult to solve.

"Lord Wang, although the people of Gaoling County agreed to irrigate, you also saw the situation here just now, there are very few laborers, and the slightly stronger ones have been conscripted, and most of the rest are old and weak women and children, let them irrigate, I am afraid that they will miss the last growth of crops."

The eldest grandson Wuji's face was heavy, no one, even if the people agreed to irrigate, what was the use?

Li Shimin naturally knew this situation, and after a long sigh, he said: "Alas, it is difficult for a good woman to cook without rice, so let's do it, after everyone goes back, they will mobilize their respective family slaves to come to the field to help irrigate." ”

It's a drop in the bucket, but that's all they can do now.

And just as they were saying this, a fast horse suddenly came running from a distance: "Lord Wang, the matter of irrigation is well solved......

Everyone looked up, only to see Qin Shubao shouting on horseback, and after a short time, he came to him, Li Shimin was a little curious, and asked, "Yiguo Gong, what did you just say?" ”

Qin Qiong couldn't wait to take out the drawings of the automatic water wheel: "Lord Wang, the irrigation matter is solved, do you see this?" ”

Li Shimin took the drawings and looked at them, and after reading them, he was a little puzzled and asked, "This is a waterwheel?" ”

The waterwheel had appeared before the Tang Dynasty, and Li Shimin was naturally clear, he didn't understand what Qin Qiong was doing with the drawings of the waterwheel.

"Lord, this is indeed a waterwheel, but it is an automatic waterwheel, it does not rely on manpower, only wind or water power, it can rotate freely, as long as it is produced in large quantities, even if there is not a lot of labor, it can solve the problem of irrigation."

Qin Qiong said excitedly, but Cheng Biting Jin pouted, and said: "Yiguo Gong, it's not that I haven't seen the waterwheel Lao Cheng, that doesn't require manpower, you said that this can be turned without people, who are you fooling?" ”

Cheng Yanjin and Qin Shubao have a good relationship, so Cheng Yanjin has nothing to say, and at this time, Chai Shao said: "Lu Guogong, Yi Guogong will not talk nonsense, since he said it is feasible, it must be feasible." ”

Saying that, everyone looked at Qin Shubao, Qin Shubao smiled: "It's indeed feasible, but I have seen it with my own eyes, just this automatic water wheel, it can keep pumping water to the roof, and then flow down from the roof, so as to circulate, it can reduce the indoor temperature, and it is like going to a summer resort in summer." ”

Hearing Qin Shubao's narration, the eyes of the crowd were curious and unbelieving, Li Shimin smiled slightly, and said: "It is really interesting to be able to circulate water back and forth, so as to achieve the purpose of reducing the warmth of the room, I don't know where Yiguo Gong sees it?" ”

After receiving Li Shimin's praise, Qin Shubao felt a little proud in his heart, and said: "Back to the prince's words, I saw it from Qin Tian, the son of the last general." ”

When these words came out, everyone present was stunned.

"I said Lao Qin, when did you have a righteous son, I remember that you will have a child with Qin Huaiyu, right?" Wei Chi Gong was anxious and immediately asked, and everyone else also looked at Qin Shubao, they had been friends for many years, and they really hadn't heard that Qin Shubao had a righteous son.

Qin Shubao smiled: "I just recognized, his name is Qin Tian, he is Huaiyu's life-saving benefactor, I was going to thank him today, I never thought that I found the self-rain house in his manor, I saw that the automatic water wheel could pump water automatically, and I thought it could be used to irrigate the fields, so I hurried back." ”

Hearing that Qin Shubao recognized Qin Huaiyu's benefactor as his righteous son, everyone didn't think there was anything about it, after all, with Qin Shubao's affectionate character, it was normal to do this.

It's just that they didn't expect that the righteous son recognized by Qin Shubao would still have the ability to invent an automatic water wheel.

"Lord Wang, if what Yiguo Gong said is true, this automatic waterwheel can really rotate by itself for irrigation, then as long as it is produced in large quantities, even if the weather is dry again in the future, it is not difficult to irrigate the crops.

The eldest grandson Wuji was worried about the lack of manpower just now, and now Qin Shubao brought the drawings of the automatic water wheel, although the eldest grandson Wuji felt a little strange and unbelievable, but he still hurriedly mentioned it, because if it was really feasible, it would definitely be a good way for Datang to save manpower.

After saving manpower, many people can do other things, which is beneficial to the people and the future. 、

The eldest grandson Wuji pulled the topic back, and Qin Shubao immediately agreed: "Lord Wang, this automatic waterwheel is absolutely feasible, if there is a big drought today, we should put it into irrigation as soon as possible." ”

Li Shimin believed in Qin Shubao, since Qin Shubao saw it with his own eyes, it would never be bad, he nodded: "This king immediately went back to Beijing to meet the saint, and after obtaining the will, he immediately summoned craftsmen to produce and manufacture it, and tested it in Gaoling County." ”

Saying that, Li Shimin flew on his horse, and a group of civil and military generals did not hesitate, followed closely behind, and rushed to Chang'an City.
