Chapter 99 requires this hardness

pulling up grass by the side of the road. ""there's more, there's more." Ximen Qing seemed to have seen the death of Wuzhi. He clenched his fist and hurriedly asked."there is another one called Bai S...the other one looks a little old-fashioned, with a bright smile on her face, and her smile will reveal a big gold front tooth.

she patted Yan Xijiao's mother on the shoulder and smiled. "Sister, you are blessed! If Xijiao can marry the landlord, from now on, she will no longer worry about food and clothing, wealth and splendor! "

Li Shi, Yan Xijiao's mother, was overjoyed, but she was still a little worried: "I heard that our landlord already had two wives and concubines, and they gave birth to immortal looks." Do you think my daughter will be bullied by this big and small woman when she gets married "

"what are you thinking Our landlord is a man of love and righteousness! And your daughter can play and sing, and she is so handsome that it is too late for the landlord to love her and cherish her. "

Li added: "I just don't know what the owner himself means."

"leave it to my matchmaker!"

No sooner had the voice of the matchmaker Zhang dropped than a man flew past them in a hurry.

it was none other than Yan Yuantong.

this Yan Yuantong is holding a heavy object in his hand, wrapped in black cloth. He was like a child who had a baby and rushed to Wuzhi happily, regardless of the subtle ambiguity between his daughter and Wuzhi.

"Master! It's done! "

Wu Zhi of course knows what makes Yan Yuantong so excited, but he didn't expect that Yan Yuantong's work efficiency is so high!

this Yan Yuantong lifted the black cloth, and what appeared in front of Wuzhi was a cement ball with two slaps!

Takesik reached out and knocked at the cement match: "that's right, that's the hardness!"

two days ago, Wu Zhi specially asked Yan Yuantong. Tell him that there is a very special object in his hand, he only knows the raw materials for production, but the proportion is not clear, Yan Yuantong needs to explore by himself.

such things mentioned by Wuzhi can be seen everywhere in modern times, and that is cement!

Wuzhi has done rough work and pasted cement before. At that time, he heard several clay masters mention the method of making cement, but he did not know the proportion.

because of his age, Wuzhi talked about all the production materials at a time. They are limestone, clay, gypsum powder, glutinous rice flour and so on.

originally Wu Zhi thought that Yan Yuantong should take some time to develop, but he did not expect that Yan Yuantong had unique conditions and creativity in this respect.

Wu Zhi grabbed the cement ball, touched it lightly with his fist, and nodded: "Yes, this is it!"

then Wu Zhi carried Jiuyang Zhenqi in the palm of his hand and slapped it hard on the cement ball!

"bang!"

all of a sudden, the cement ball broke into pieces and the dust scattered.

Yan Yuantong's eyes are round and his mouth is wide!

"Master, this and this cement ball can't be broken with a hammer, so how can it be in your hand"

Wuzhi laughed: "the external resistance of this cement ball is very strong, so I used internal strength to shatter it from the inside."

"if a few steel bars are inserted into the building, the hardness of the cement can be supported and extended."

"in addition, when we play with cement mixed with sand and broken stone, we can achieve a harder effect than rock." In that way, the cost of casting will be reduced, the speed will be accelerated, and even on the cliffs, a fortress can be easily built! "

what Yan Yuan listens to is that his eyes are bright!, teacher Li thanked him for saving his life for those children."Wuzhi grinned: "this is what I should do, and I must do it."Wuzhi soon realized that the environment in which he and Master Li were tal...
