Regarding the newly invented things, Li Qinzai, Li Tao, and Li Cui have their own attitudes.

Li Qinzai's attitude is that it doesn't matter, he can draw a few drawings with his hands, in this era when science and technology are basically equal to primitive societies, and he can do his best to improve the scientific and technological level of Datang, which is beneficial and harmless to himself and others.

Li Cui's is Erlang's wife in the house, Li Zhen's eldest son Li Zhen served as a assassin in Zhaozhou, and the husband and wife are in the local area all the year round, and the accounts of the British government are now in charge of Erlang's wife Li Cuishi.

After managing the accounts, he naturally has to worry about the income in the house, and his son is constantly making new things, which are all money, so Li Cui's family wants to realize his son's invention.

As for Li Tao, his mind is in the court and the world.

Li Qinzai's pulley set, Li Tao's first thought was not how much money he could make, but how far-reaching impact and changes he could have on Datang after being used in the world.

The minds of the three generations were different, and for a while there was some silence.

"The thing is here, I'm going to catch up on sleep, grandpa, mother, the child is gone." Lee Yawned and wanted to slip away.

The thing was invented, and he didn't care about the next thing, anyway, he just needed to know that my family's account room was planted with ten thousand years of youth, and he was waiting for him with open arms......

As soon as he took a step by raising his legs, Li Qinzai suddenly felt that his back collar tightened, and then he found that he was being picked up by Li Tao.

An old man who is almost seventy years old, and his strength is still so great, he must have eaten a lot of ginseng and cordyceps on weekdays.

"Boy, do you want to run away when you're done?" Li Tao said dissatisfiedly: "Shake your hands neatly, do you leave the mess to the old man to clean up?" ”

Li Qinzai was stunned: "What's the mess?" ”

"You got this thing, and then what? What is it used for? How to popularize the world, how to use it for kings, and how to improve people's livelihood? Don't you care about any of this? ”

Li Qinzai was shocked: "I also have to take care of these?" ”

Li Tao carried his back collar and shook it easily, as if shaking half a bottle of aged vinegar.

"You are the only one in the world who knows this thing best, and this thing is used in the Tang Dynasty army and the people, and it is of great use, you don't care who cares?"

Li Qinzai's mind is changing, the steward has to be an official, and when he is an official, he has to clock in every day, and he has to be involved in endless officialdom intrigues, and he has to accompany his boss with a smile......

Isn't this still a social animal?

"Grandpa, my grandson didn't wake up today, Meng Lang was for a while, this thing is actually useless at all, you just treat your grandson as if you didn't do anything, and let the blacksmith quickly throw it into the furnace and melt it."

Li Qinzai made a decision immediately, he didn't mind improving the level of science and technology in Datang, but if he wanted him to return to the social animal life in his previous life, he would definitely not do it!

Li Cuishi finally couldn't help it: "How can it be useless? Our blacksmith made it, sold it to the army, or sold it to the Ministry of Industry, a lot of income a year......"

The more he spoke, the quieter he became, because Li Tao was already full of disapproval.

"This thing should not be taken lightly, it is of great use in the people and the army, the Li family cannot be privately owned, it should be dedicated to the Son of Heaven and used in the world." Li Tao said in a deep voice.

Li Cui's didn't dare to talk back, although he was still thinking about cashing things out in his heart, but Li Tao was the head of the family, and Li Cui's didn't dare to disobey his decision.

"Yes, everything listens to Ah Weng." Li Cuishi said helplessly.

Li Qinzai's heart moved, and he coughed and said: "Grandpa, the grandson has made things, and I don't care about other things, my grandson is indifferent, and he only asks about the geometry of heaven and earth, and the trivial matters in the mortal world, the grandson ......."

Before he finished speaking, Li Tao snorted: "Bastard, do you really think you are a god?" I also asked Tiandao, Tiandao is so busy, do you know your notorious little bastard? ”

Li Qinzai sighed gloomily.

wanted to set up a fairy character, but it collapsed as soon as he opened his mouth......

…………

Li Qinzai wants to be a shopkeeper, he doesn't even have to find a reason, he just wants to be lazy, he just wants to be a waste.

Li Cuishi couldn't be lazy, because she was in charge, and according to Li Tao's instructions, she summoned the blacksmiths at home to build more than ten sets of pulleys.

Li Qinzai spent a little more effort to transform the pulley group, so that it can not only lift heavy objects, but also move in parallel, which can be regarded as a miniature version of the gantry crane in the previous life.

After the transformation, the role of the pulley block is more and more not to be underestimated, Li Tao couldn't help but be overjoyed after trying it, and immediately ordered someone to send a set to the Ministry of Industry.

The Shangshu waiter and the master craftsmen of the Ministry of Industry couldn't help but be surprised and delighted after trying it, so Yang Fang, the secretary of the Ministry of Industry, hurriedly played Shangshu Province.

Layer after layer, up to heaven.

In the Taiji Palace, Li Zhi and Empress Wu stood side by side outside the hall, watching the master craftsmen of the Ministry of Industry meticulously build the pulley set.

Once the conical iron frame is installed, it is easy to lift the heavy load, and then move it to another place by translation.

The whole process is extremely easy, and almost only one person is required to operate from start to finish.

The more Li Zhi and Empress Wu looked, the more shocked they became.

What was taken for granted in the previous life, changed to a backward era, and the psychological impact on them was unimaginable for future generations.

In this era when knowledge of physics and mathematics was almost zero, the pulley set built by Li Qinzai was as incredible as a miracle.

"Shhh

Empress Wu's eyes shone brightly, and her eyes flashed with consternation.

"This thing...... It was made by the grandson of the British prince again? Li Zhi said in disbelief.

Yang Fang, the secretary of the Ministry of Industry, bowed and said: "Yes, this morning, Old Man Li sent someone to send this thing to the Ministry of Industry, and it was also rumored that it may be of great use to Sheji, and the ministers and craftsmen have been careful for a long time, and found that what the old man said is true." ”

Li Zhi glanced at Empress Wu speechlessly, and said with a smile: "That grandson of the British Duke has been very surprised recently. ”

Empress Wu also smiled and said: "Yes, I really don't know what kind of elixir he has taken, and he has suddenly become so smart, and the concubines can't believe it, is this still the gentleman who is hated all over the city?" ”

Li Zhi sighed: "The prodigal son turned back and knew his way back, and that's probably it." ”

Empress Wu said with a smile: "After knowing that I have lost my way, I am a blockbuster and sharp, and it will not be long before the world hears about it." ”

Yang Fang, the secretary of the Ministry of Industry, said in a low voice: "Your Majesty, this thing is quite important to the Tang Dynasty, it can be used for construction, city defense, fortifications, military baggage, etc., if it can be popularized, it can save tens of thousands of people every year, light the world's endowment, and the Son of Heaven will be favored by the people." ”

"The young man of the Li family created this thing, and he made an indispensable contribution to the Tang Dynasty."

Li Zhi smiled, his eyes moved slightly, and he suddenly walked down the stone steps, came to the pulley group, and said with a smile: "I will try this thing myself." ”

Under the guidance of Yang Fang, Li Zhi personally pulled the iron chain, and thousands of pounds of heavy objects were easily lifted, translated, and landed, from one place to another, separated by several zhang, and it originally took more than ten labors to move it, and Li Zhi could complete it alone.

According to this calculation, what Yang Fang just said can save tens of thousands of people from forced labor, which is indeed true.

After trying it himself, Li Zhi couldn't help but be overjoyed, and said with a smile: "It's really a good thing, the Li family's unicorn lives up to my expectations!" ”

Li Qinzai made a divine arm bow and a horseshoe, Li Zhi just admired him, and it would not be too much to say that Jane was in the emperor's heart.

But this time, a pulley set was created, which had a profound impact on Datang Sheji, and Li Zhi already had a very deep positive impression of Li Qinzai at the moment.

Li Zhi was a wise monarch, and his thirst for merit was not inferior to that of his father, Li Shimin. If a person like Li Qinzai is not considered a talent, who can be counted?

After calming down his emotions, Li Zhi looked at Empress Wu and said, "What does the Empress think of Li Qinzai's son?" ”

Empress Wu thought for a while and said: "The divine arm bow, the horseshoe, and this thing called the 'pulley group', after the white jade Pegasus case, but in the rest of the month, Li Qinzai has successively created these things that are of great use to the community, this son has been reborn, shining brightly, and can be reused." ”

Li Zhi nodded and said: "Yes, this son is a talent, Datang is now in undecided external troubles, and there are a lot of internal worries, it is precisely when talents are needed, this son comes out of the sky, maybe it is the will of God." ”

Empress Wu said with a smile: "God-given ministers, assist Your Majesty to set the country and create a prosperous era." ”

Li Zhi laughed, obviously in a very good mood.

"Come on, Xuan Li Qin will enter the palace and play right."

The sound is like dust falling from nine days, echoing outside the Chang Close.
