Wang Jiawei is the captain of the Youzhou Keju team, and every year on the ninth day of July, he will lead the Chengdong team and the Chengxi team he trained to have a Keju battle.

This year's Keju match on the ninth day of July was very exciting, and his team took a four-goal lead and defeated the Josai team before the thirtieth pillar of incense was burned.

Wang Jiawei is very satisfied, and his team is very good.

Youzhou Wang family is also a big family, Wang Jiawei as the only son of the Wang family, has always been a collection of thousands of favors, he has no hobbies since he was a child, he likes to juju, the family is also actively to meet his hobby, even the annual July nine juju competition is held at the expense of the Wang family.

Because he likes it, Wang Jiawei's ball skills are very good, whether it is for white or indirect, he can firmly control the kick on his feet, so he is known as the first doctor of Juju in Youzhou.

The game on the ninth day of July had just ended, and because of the win, Wang Jiawei rewarded the eleven members of the Keju team, each with five yuan.

Just when Wang Jiawei's reward was over and everyone was about to return home, a short-haired young man dressed in spectacle clothes stopped everyone. Wang Jiawei didn't want to pay attention to this person, but the young man said something that stopped him

"Jiawei! Catch! A shout in the distance called Wang Jiawei back to reality.

I saw in the distance, a gray and white football galloping towards Wang Jiawei, Wang Jiawei deserved to be immersed in the ball for many years, a little ball on his feet, and then on his heels, and suddenly stopped the speeding ball.

In front of him, two men's men suddenly rushed out, these two strong men stared at the football at Wang Jiawei's feet, with a domineering expression that people were on the ball and the ball was dying.

The corners of Wang Jiawei's mouth showed a light smile, and he saw the wind under his feet, the football was constantly dangling between his feet, and the two strong defensive men were suddenly dizzy.

Suddenly, Wang Jiawei moved, as fast as wind and thunder.

The two big men subconsciously deviated from the center of gravity in the direction of Wang Jiawei's movement.

However, no one thought that this was Wang Jiawei's plan to turn the tiger away from the mountain, as fast as lightning, the body fell in the opposite direction, the two big men knew the plan, and hurriedly strode to turn the center of gravity, at this time, I saw Wang Jiawei's mouth The corners of his mouth showed a successful smile, taking advantage of the big man's big stride, the empty door was wide open, Wang Jiawei's left foot was lightly picked, and the football passed easily through the crotch of the big man.

What a trick 'wearing the crotch'!

Wang Jiawei who passed through the crotch did not pause at all, he was like a wolf into a flock of sheep, running wildly all the way, the chicken and the dog jumped into the penalty area, when the last defender on the opposite side swept the tackle quickly, Wang Jiawei lightly picked, let the ball fly slightly, and avoided the tackle.

Facing the goalkeeper standing in front of the goal, Wang Jiawei's mouth showed a contemptuous smile, and he saw him raise his right foot high.

"Bump!" A violent crash resounded across the pitch.

Shoot with a single shot!

The ball flew fast and hit the top right corner of the net.

The ball is in!!

"Shh!!h ~" The referee blew the whistle at the end of the game, "I announce that the Chengdong team defeated the Chengxi team 3-2 in this friendly match!" The referee gave the order, and the players of the Chengdong team suddenly broke out into a burst of joyful cheers.

"Yay! Jiawei! The last shot is so handsome! ”

"Great! Jiawei! ”

"Jiawei! Well done! ”

Wang Jiawei gasped, he felt very tired, but very happy, this confrontational style called "football" sports made me deeply fascinated, the feeling of blood boiling all over the body during the battle, the fierce friction with the opponent's body, the fighting spirit of fighting on the field, this kind of sports called "football" is a real man's game! Keju's white fight and indirect confrontation are like a child's play.

Wang Jiawei thought of what the young man said to him again, do you want Datang's Keju to be proud of the world?

Do you want Datang's Keju to be proud of the world?!

Every time Wang Jiawei thinks of this sentence, his whole body will be full of blood, football! It can be realized, so that Datang is proud of the world!

"In the future, we will play football games in a huge football stadium, tens of thousands of people will watch the game, and I, Datang, will use football to teach those barbarians what a big country is!"

"I, Datang, will use football to teach those barbarians what a big country is!" Wang Jiawei silently recited what Xu Yang had said, and his heart couldn't calm down for a long time

"Yes, yes, this brick is here." Xu Yang held the construction drawings while directing the hundreds of slaves present to work.

He is building the stadium that he promised Liu Mengli a long time ago.

This stadium is too huge, and it can't be held in Youzhou City, so Xu Yang directly built the stadium in the east of Youzhou City.

When the site was selected, it happened that the east of the city was a large area of grass and woods, Xu Yang sent someone to uproot all the trees, these grasses were just used as the turf of football, and the original uneven places were filled and dug flat, Xu began to build, first of all, the problem of drawings was solved, Xu Yang did not build a world-class gymnasium with a shed, just built an open-air gymnasium, leaving four large exits, a large stadium in the middle, surrounded by high platforms, one step at a time, convenient for the people to sit on it and watch.

Of course, there is a special viewing table for the privileged class, and the angle is the best.

The drawings are no problem, and then there are raw materials, this is what makes Xu Yang a headache, and now Zhang Wu of the urban management team takes a group of slaves to open mountains and blow up stones in the north mountain every day, and there are rumors in Youzhou City, saying that the mountain gods play drums, Xu Yang doesn't take it too seriously, and just transport enough stones.

Limestone, clay these Youzhou cities are not too much, iron ore is okay, limestone because it is also a raw material for glass, it is even more in demand, almost in Youzhou has not been seen, to buy need to buy several other nearby cities.

Xu Yang was a little irritable, where should he go to get cement when the cement is used up now.

Natural mining dolomite, limestone production is too low.

Suddenly, he thought of something, took out his mobile phone, clicked on the browser, and searched for it in Baidu: how to make limestone.

Unexpectedly, the pop-up page really made him overjoyed, and the headline of Du Niang's Baidu Encyclopedia clearly wrote: The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are used in large quantities as building materials and are also important raw materials for many industries. Limestone can be processed directly into stone and fired into quicklime

"Haha~ There is a question, ask Du Niang, I forgot to burn this thing" Xu Yang patted his head, took out a homemade pencil, and carefully copied a few chemical formulas on the paper;

CaCO3==CaO+CO2↑

CaO+H2O→Ca(OH)2

Ca(OH)2+CO2→CaCO3↓+H2O

Then he took a piece of paper and wrote a long section of the process of how to make zuò limestone.

The method of making zuò cement Xu Yang has already taught the team of craftsmen of the Liu family, and many of the scientific principles of later generations have also been poured into them, and they do not understand without management.

At home, those craftsmen have a printed copy of the "Cement Process", which has been studied for more than half a month, and many craftsmen have carefully studied it, and most of them can understand the ratio, hardness, density, calcium Ca and other modern words.

Among them, a small steward of the Liu family, named Liu Neng, is the smartest, this Liu Neng is not at all different from Liu Neng in later film and television works, with a fat belly, which is a bit unusual in the generally thin Tang Dynasty, Xu Yang likes to call him Liu Da Fat, he looks like he is Xie Xu Yang gave his name, and he really changed his name to Liu Da Fat, although this Liu Da Pang looks fat and big-eared, but he is very thoughtful, loves to study, loves to ask why, is a natural scientist.

Xu Yang has now arranged him to be the head of the entire cement production department, and he has lived up to expectations, resulting in several problems in the production of cement, and he also mentioned that when the cement production capacity is larger, the cement department and the brick burning department will be moved outside the city together to facilitate management, which was agreed by Xu Yang.

"Liu Qi." Xu Yang shouted Liu Qi loudly.

"The little ones are here." Liu Qi said respectfully beside Xu Yang, what Xu Gongzi did was a miracle, and he couldn't understand it, and it was already a blessing to be able to run errands for Gongzi.

Xu Yang looked at the things written on a few pieces of paper, and after making sure that it was correct, he stuffed it into Liu Qi's hand and said to him: "Now you take this piece of paper and ride a bicycle back to the city to find Liu Dapang, who is refining cement, and tell him to get limestone by doing it according to this, and tell him to hurry up and make cement." ”

"Gotta ~ the small ones will do it." Liu Qi stepped on the bicycle quickly, he liked to do the tasks assigned to him by Xu Yang, the tasks given by Childe were never troublesome, and he didn't have to think about it, as long as he did what Childe said, it must be correct, which made him feel very useful and respect Xu Yang even more.

Watching Liu Qi ride away on a bicycle, Xu Yang showed a knowing smile.

"A few of you, lay the bricks on this side, and remember that the cement should be evenly smeared."
