Li Yu listened to the endorsements of the two children, and from time to time she had to ask questions for random exams, but fortunately, the two children were smart, answered fluently, and studied seriously.

"I'll go home in two days and take you back to my grandfather."

Li Yu saw that the child was serious in reading and did not slack off, and nodded with satisfaction.

"Bring snacks to my grandfather, my aunt and uncle, and my aunt."

Brother Xu is talking about the Wang family.

"Okay, whatever snacks you want to eat, my sister rewards you for studying hard."

Li Yu pinched his younger brother's chubby little face.

These days, Brother Xu's mental outlook has improved greatly, not only his complexion has improved, his little face is round and fleshy, and his eyes are also smart and bright.

Brother Xu snuggled in her arms and coquettishly, "I want to eat osmanthus cake, ginger candy, rice cake..."

Li Yu nodded, "Okay, what's delicious about ginger candy."

Mrs. Wang glanced at her, "You don't like to eat and you don't allow others to eat, pick your mouth, and you're still hungry." ”

Li Yu laughed.

"Brother Yang, what snacks do you like, my sister bought it for you."

Xu Yang smiled shyly and scratched his head, "I love to eat rice cakes, sugar cakes, and sugar gourds, and my father would buy them for me when I was a child." ”

It's all cheap food and things to coax children, and sugar is very expensive for children from poor families.

"Okay, buy it."

Li Yu waved his hand, very refreshing.

Wang and his aunt entered the door together.

"Where did you two come from, and how did you get together?"

Li Yu asked curiously.

"I have to report to you where I'm going, really..."

Wang gave his daughter a blank look.

"That's it, how can you be a housekeeper at such a young age!"

Wang Yue also raised her eyebrows proudly and raised her chin, pulling her sister's sleeve to demonstrate to Li Yu.

Li Yu pouted, "I won't rely on my mother when I'm five years old, you are so old and still rely on my mother, don't be ashamed." ”

"I'm not ashamed."

Brother Xu applauded.

A room full of people laughed, and the second old man laughed so happily.

Wang Yue came over angrily and twisted Brother Xu's ears, "Stinky boy, you ate my dim sum before, and now you turn your face and don't recognize people, you have no conscience." ”

Brother Xu blinked, his voice crisp, "Don't bully my sister, don't rob my aunt with me." ”

He relied heavily on Li Yu and Wang.

"Just rob it, you are a boy, don't rely on your aunt, a man must stand up to the sky."

Wang Yue grabbed the white unceremoniously.

Brother Xu stretched out his hand to compare his own size, and then compared her size, silently mocking.

Who's bigger and who's small.

"Hahahaha!"

Li Yu raised his head and laughed, made Wang laugh too, and patted his sister, "Let the child laugh at you." ”

"Humph!"

Wang Yue sat down to speak.

"I heard you're planning to do a new machine manufacturing?"

"Yes, it's going to be redone, I've been studying for a while, I have a little less free time, and there are still a lot of things that haven't been made."

Li Yu came out with the manufacturing diagram of the core mechanism, this alone is not enough, and ready-made molds are also needed.

That is, the toys that Brother Xu played, such as the carriage sold to the Du family, can also be converted into a chariot, and a reduced version of wood can be made, so that the clansmen can learn to compare the specific size, and then they build a wooden and proportionally enlarged version of the chariot, and then according to this wooden, one to one to build fine iron.

This matter is very troublesome, and the specific core still needs to be watched by Li Yu and his clan brothers.

The same is true for weapons, which can also be used as other household utensils, such as water wheels and other civilian equipment, which are also very sold.

Mechanism manufacturing is not only used for warfare, but also plays a great role in life and civil use, such as quarrying rocks, saving a lot of manpower for the construction of city walls.

There is also the most famous, the wooden ox flowing horse, which replaces horses to transport grain, reducing the expenditure of manpower and financial resources, and plays a huge role.

War horses and cattle are all to eat grain and grass, wooden cattle and horses do not need to run, people can control them to run, at most a few sergeants are needed to guide the route and guard the military rations.

"What are you going to use to fire the first shot?"

Wang Yue looked at Li Yu, full of pampering and trust.

"Brother Xu, bring the Trojan horse."

"Don't break it."

Brother Xu is very precious to his toys.

took a Trojan horse out and handed it to Li Yu.

There is a bucket behind the wooden horse that can hold things, and the toys are reduced in equal proportions, the size of a child's palm.

But the horse's hooves are very strange, Li Yu broke out the horse's hooves, which are special mortise and tenon structures, folded in, can also be opened, and open is a wheel.

Li Yu threaded the thread on the carriage in a fixed position, and then wound it, and saw that the little wooden horse slid forward by itself, and with a slight flick of his hand, he could turn around.

Li Yu picked up the Trojan horse again, put the hooves back into place, and the Trojan horse began to walk with his legs raised, walking steadily.

Wang Yue and Old Man Wang's eyes lit up instantly.

This is the legendary wooden oxen and flowing horses, which are used to transport military rations and save manpower, material resources and horses. This one of yours is even better than what I read in books. ”

"Yes, I have improved the way of walking with the horse's hooves, you can walk on wheels on a smooth road, or you can walk on all fours, which is suitable for walking on more rugged roads, this is a seat that can sit on a person to drive a carriage, and human control is more flexible and free."

"Dad, this is too good, this doesn't need to eat grain and grass, just a few people to escort the car."

"Yes."

"This hooves can be replaced, in order to avoid rough roads, the hooves will be damaged, here is a buckle to replace the hooves, can also be made of fine iron, not easy to damage, wood is cheaper."

Li Yu played tricks and essences of mechanism manufacturing, which was breathtaking, and all aspects and possible problems were thought of.

"Does your dad know you have this?"

"I know, my father won't let me make it bigger, for fear of attracting attention, so I made toys for my brother to play with."

"Yu'er, will you take me for this business?"

Wang Yue's business and financial management came from the true biography of the Wang family, and his business was doing well.

Wang Yue picked up the wooden horse and looked at it in his hand, "Give me this, I'll go back and discuss with the clan elders." ”

"You still help the clan to do business, then forget it, if you are alone, I will let my father and mother share your share, we are a family, and the clan of your family can be pulled down, and I bullied your orphans and widows at the beginning."

Li Yu is very short, pouting and not willing to help his aunt's ungrateful in-law.

Old Madam Wang smiled and patted her gently, "Don't talk nonsense, the Wei family is not weak, there were indeed people who were greedy to swallow your uncle's property, and the clan was not a family." What's more, your cousin's surname is Wei, how can you do it without the support of your clan in the future, and let it pass if some things can be passed. ”

Li Yu raised her eyebrows, "What's the matter, there is no man to support my aunt in bullying, why didn't you say that this would be a pole to beg for help when I bullied people at the beginning." The Wei family must have been in trouble before they came to ask for help. ”

"Little Fairy Bean, let you speak. The Wei family is also engaged in silk and other businesses, before people robbed boats and things, and lost a lot, please your aunt's head, I didn't plan to take care of it in front, and you came back later, if you want to do iron ore business, you need to use the Cao Gang, this is not the Wei family's heart, and I begged your aunt several times. ”

Mrs. Wang told the truth.
