Yang Xing's samples of pottery pipes and fittings were made in two days, and then he personally invited Qu Wu to his workshop to see them.

Although these clay pipes look rough, they are exactly the same in size, and the accessories such as straight and tee are also very cleverly matched.

Qu Wu did an experiment, and tied a little plastic film to the junction when connecting, and not a drop of water could seep out.

The toilet bowl is also very well done, almost exactly like the picture drawn by Qu Wu.

"Uncle Yang, you are too powerful. Just do it like this, make 500 thick and thin pipes first, 50 accessories each, and 10 toilets first. Qu Wu said.

"Okay, Mr. Qu."

"Uncle Yang, don't let others learn your key technology, and don't show the drawings to others, you will make a fortune in the future." Qu Wu said seriously.

"Thanks to you, definitely."

Qu Wu saw that the water pipe and toilet were made, and after coming out of Yang Xing, he went to the lobby to draw the drawings of the ball valve, found one of the most famous copper products processing workshops in Yingdu, and commissioned them to make samples.

The Wat Wood Workshop commissioned them to build a wooden water tower about three stories high to provide potential energy for the flow of water.

Due to the lack of electricity and pumping machines, the water supply of the water tower could only be supplied manually, so Qu Wu designed a device to press the water. Although the principle of this device is simple, it took him a lot of effort to turn it into a drawing, but fortunately, the physics course he had studied before was not in vain.

After doing this, Qu Wu went to the Qingya Teahouse to drink tea leisurely.

Qu Wu walked to the teahouse, and when he went upstairs, he saw Sang Zhi and Mi Hong waiting for him upstairs, Qu Wu said: "Master Sang, I haven't seen you for many days, what kind of wind blew you here today?"

"Haha, Dongfeng, I came today to invite the two of you to dinner." Sang said after shaking his hand.

Qu Wu returned the salute and said, "Lord Sang's face is full of spring breeze, it must be that something good is coming."

Sang Zhi led Qu Wu and Qi Hong into the private room he had booked, and there were already three tables in it, and wine and food were placed on them.

"Mr. Qu, please bow to Sang Zhi first." After entering the private room, without waiting for Qu Wu to react, Sang Zhi had already knelt on the ground and kowtowed, and Mi Hong on the side was taken aback.

Qu Wu hurriedly stretched out his hand and pulled him up: "Master Sang, you can't do it, you can't do it."

"Mr. Qu, you are really a living immortal, according to my wife, I was already dead that day, and you dragged me back from Lord Yama, it's amazing." Mulberry said emotionally.

"Ah, what else is that? San-sama, what's going on? Qi Hong asked.

Qu Wu waved his hand and said, "It's a trivial matter, why bother?"

"It's a small thing for you, but it's a matter of life and death for me. Qu Wu, you are the person who reincarnates my Sang Zhi, I am not grateful, from today on, as long as you do not dislike it, you are my own brother, and if you have any difficulties in the future, I will definitely stick a knife to help. Sang Zhi said.

"Lord Sang is serious, but if you treat me as a brother, I will also treat you as my brother, you are older than me, and you will be my Qu Wu's own brother in the future."

"Okay, Brother Qu. Mi Hong, you testify, I want to be friends with Brother Qu Wu for life and death. Sang Zhi said, picked up the wine on the case, and Qu Wu also picked up the wine on the case.

Sang Zhi held up the wine with both hands and swore to the sky: "The emperor is above, today I am a brother with Qu Wu, and I do not seek to be born on the same day and month of the same year, but to die on the same day and month of the same year."

Qu Wu was very moved when he saw Sang Zhi's true temperament, and he also held up the wine and swore to the sky: "The emperor is above, today I am a brother with Sang Zhi, and I do not seek to be born on the same day and month of the same year, but to die on the same day and month of the same year."

After taking the oath, Qu Wu and Sang Zhi drank all the wine in the wine at the same time.

After drinking the wine, the three of them sat behind the desk, and Sang Zhi said again: "Brother Qu, you not only saved my Sang Zhi's life, but also the reinventor of our Sang family, if you don't seriously investigate the affairs of my two wives, they will always bear the notoriety of uncleanness, and my three children don't know what kind of future they will face."

"Since we are brothers, it is only right to do all this." Qu Wu said.

"The problem is that we didn't worship before today, but Qu Wu, you are still so righteous and awe-inspiring, and you are really admirable." Sang Zhi said.

"Hehe, maybe I had the foresight, and if I did this, Lord Sang must treat me as a brother." Qu Wu said with a smile.

The three of them were very interested, but Sang Zhi never mentioned the matter of Zi's return, of course Qu Wu was not good to ask, Mi Hong wanted to guide the topic in this direction, so he asked: "Master Sang, I heard you call the Wang family Mrs. just now, do you renew the old relationship with the Wang family?"

"Oh, yes. I plan to remarry Fan and Wang, and it will be more solemn than the last time I married them, and I have come today to invite you to participate. Sang Zhi said.

"Congratulations, big brother. This is really a great joy, you can mention what I need to do, as long as I can do it, there is no ambiguity. Qu Wu said.

"If you have free time, help me go to greet my relatives, and you can also bring your wife and friends." Sang Zhi said.

"Okay, that's a deal." Qi Hong said.

"When the family affairs are done, I will return my adopted son to Ziyan. This kid is very smart, and he seems to be aware of this in the past few days, and he seems to be particularly clingy to me and my two wives, after all, living together for so long, not to mention that it is really a little reluctant. Sang Zhi said.

Qu Wu listened to what Sang Zhi said, and his heart was ecstatic, and his efforts these days were not in vain, and said: "This shows that the eldest brother's family is kind and loving, and he has also done a good job in educating Zigui."

"Where, brother has won the prize. Anyway, we have a clear conscience. ”

"It's messy, it's messy, big brother, I'm a brother to you, your adopted son should be a generation younger than me, but he is Ziyan's younger brother, how will he call him in the future?" Qu Wu suddenly realized that something was wrong.

Sang Zhi was also stunned when he heard this, and said, "I forgot about this stubble when I was excited just now."

Mi Hong on the side laughed and said, "This is still not easy to solve? When the two of you are together, you can call yourself brothers, but you can only keep silent in front of your brothers and sisters. ”

Qu Wu nodded and said, "It's still Boss Mi who is smart." But don't worry, big brother, I believe that Zigui will visit you often in the future and be filial to you. ”

After eating, the three of them chatted for a long time before they dispersed.

Because of the news of Zi's return, Qu Wu came out of the Qingya Teahouse and went to the Zi's mansion and informed Ziyan of Sang Zhi's decision.

After hearing this, Zi Yan hugged Qu Wu and cried with joy, Zigui is the hope of the Zi family to restore the hereditary title, and now Sang Zhi finally agreed to return it himself, and the Zi family finally has the possibility of revival.

Zi Yan hurriedly came to the sacrificial hall with the spiritual seats of her ancestors, grandfather, and father, and knelt to inform the ancestors of the news that the Zi family was about to return to glory.
