Liu Heng left.

But Liu Chang's heart couldn't calm down.

It's been a while since he came to this world, and in these days, Liu Chang has been complaining, he feels that he doesn't like this backward era at all, he also feels that he doesn't belong here, he doesn't understand the meaning of coming here, he has already given up thinking, and is ready to be a prince and king with peace of mind, and spend this life together.

But Liu Heng's words suddenly woke him up, if the small thing he was about to make on his temporary basis had the power to benefit the whole world, then why didn't he do more?

Instead of wasting time in Tianlu Pavilion every day, it is better to do something meaningful.

This is probably the first time that Xiao Liu Chang has become so serious, and for a whole day, he stood in front of his mother's spinning wheel, carefully observing this spinning wheel.

Although the principle is almost the same, but this thing is still very different from the textile machine of later generations, Liu Chang dismantled the textile machine that was many, many years ago, before he really started, he had to make a draft.

Liu Chang has a lot of paper here, but these papers are very precious, not to mention the prince, even Liu Bang, who rarely uses paper, and more uses bamboo slips. Liu Chang obtained these papers by his own efforts, which he stole from the great Confucian who had taught him before.

Just when Liu Chang was observing the spinning wheel and thinking about how he should make it, Empress Lu had already returned.

Empress Lu didn't know where she went, in short, she was not very happy, she seemed to be angry, but Liu Chang, who was in deep thought, didn't notice her, Empress Lu walked straight into the inner hall, changed her clothes, and when she came out, she saw that Liu Chang was still squatting in front of the spinning wheel to play, so she didn't care.

It wasn't until the palace maid told Liu Heng about coming to Liu Chang that it aroused Empress Lu's curiosity.

"Long, come here."

Liu Chang woke up in shock, and then he rushed to Lu Hou's side with a smile.

"Mother~~"

"Heng has been here?"

"Yes, the fourth brother came once in the morning."

"What is he doing here?"

"It's nothing, just brought me a gift, hehe.."

Liu Chang grinned, obviously very satisfied with this gift.

Empress Lu frowned, she stretched out her hand, dragged Liu Chang into her arms, and said solemnly: "If you ask for someone, you will go first." ”

"What do you mean?"

"If you want to be asked of others, you must first live under them."

"No one will show you kindness and give you gifts for no reason, and if someone does that, then you have to be careful, because they probably have other ideas and bad intentions."

Liu Chang was stunned for a moment, and said with some surprise: "But I don't think the fourth brother has bad intentions for me."

"I'm not saying that your fourth brother is not good, but you have to keep my words in mind, understand?"

Liu Chang nodded, thoughtful.

"Go play, the spinning wheel is for you, don't hurt yourself."

Liu Changxi was about to peck at his mother's face, but suddenly, he realized something, his expression became solemn, and he muttered: "If you ask for someone, you will go first?" ”

For the first time, there was consternation on Empress Lu's face that was not shocked.

She slapped Liu Chang on the back of the head and scolded, "That's not how it works!" ”

If Empress Lu knew that her gift would open Pandora's cartridge and raise a "palace demolition demon" in the palace, I am afraid that she would not give the spinning wheel to Liu Chang....

Liu Chang spent two days drawing a slightly professional design drawing of a textile machine.

"Heald frame beam, heald frame drive rope, heald frame, reed upper rail, reed, shuttle, heald, reed lower rail, reed fixing bolts, weft, roll shaft, ratchet brace, pinched shaft, frame.... Pedals, rocker arms, warp threads, warp bars, heald pulleys...."

That's right, Liu Chang has given up his original idea, he just wanted to improve the spinning wheel, but after hearing Liu Heng's words, he decided to build a state-of-the-art textile machine! In the field of wood materials, the textile machine he designed is definitely the most advanced.

These builds are all made of wood, so that the material will not be a problem, and the big man has wood.

But when Liu Chang was about to do it, he found that it was not enough to have a saw, he also had to have a ruler, otherwise he would not be able to measure the length, and in addition, it would be better if he could get a planer, file, and axe. But Liu Chang was embarrassed to continue to ask Liu Heng for it.

Liu Heng can easily go to the next door to find a craftsman, but he can't get out, this is due to the bad character of his predecessor, probably because he is afraid that he will go out and beat others...

Liu Chang decided to wait until the Tianlu Pavilion opened school, and then find an opportunity for Liu Heng to take him to the next door, to borrow a ruler, planing, filing or something, even the saw can be borrowed, and it is probably not difficult to borrow a few more tools, before that, he still has to prepare more materials, and he can use them directly when the time comes.

The spinning wheel was quickly dismantled by Liu Chang, and the shuttles, rocker arms, pulleys, pedals, etc. in the spinning wheel can be used directly without too many changes, and Liu Chang decided to remake them on the basis of these things.

But the loom he wants to make is at least two turns larger than the spinning wheel in front of him, and these materials alone are not enough.

So, he walked around the palace with a saw all day, looking around for materials that could be used... Whenever he picked up the saw and compared it in the Jiaofang Palace, the palace maids were scared half to death, for fear that he would cut off the main beam in the hall.

Of course, give Liu Chang ten guts, he didn't dare to demolish the old lady's Jiaofang Palace, don't look at Liu Bang's fierceness, in fact, Liu Bang's attack is still relatively light, Liu Chang remembers that he threw stones outside the palace to play, and smashed a big bag on his uncle's head.

The eldest uncle didn't care about this, just hugged him with a smile, saying that he was not injured when he went to the battlefield, but he didn't expect to be planted in the hands of a little doll.

However, the eldest uncle did not hold him accountable, and the mother was so angry that Liu Chang couldn't stay for three days, and his buttocks were swollen.

The eldest uncle is a good person, when he was still alive, he would accompany Liu Chang to play every time he entered the palace, but the second uncle always had a stiff face, like his mother, and did not smile.

Weiyang Palace was built, so the palace has not yet reached the point of lushness, and the wood is not so easy to obtain, at this moment, the Han Palace, it looks a little desolate, everywhere is gray and white, and there is no time to color, from time to time there are eunuchs passing by with their heads down, in a hurry.

Liu Chang inspected the palace for a long time, and finally found a place to obtain precious raw materials.

First of all, this is not the beam of the main hall, there will be no danger, and no one comes here at all, it is just an empty decoration, there is no practicality, it is better to let yourself use it for the benefit of the common people in the world.

Liu Chang hid the wood he had obtained nearby, and every day he returned to the Jiaofang Hall with a disgraced face, and fell asleep.

Empress Lu looked at him who was sleeping soundly and looked at the palace maid on the side, "He is still building that spinning wheel?" ”

"Yes... Childe is also a piece of filial piety..."

Empress Lu didn't say anything more, in fact, as early as the day after Liu Chang had this idea, Empress Lu already knew the surprise that this guy was going to give him, the lord of the harem is not joking with you, whenever there is some turmoil in the palace, Empress Lu is usually the first to know.

Empress Lu was the first queen of China, after all, the first emperor of China did not canonize the queen, and this era still did not know how to treat the queen, nor did she know how to determine the power of the queen, and the harem was not allowed to interfere in politics and did not appear. Therefore, the power of the empress is great and scary.

Not only can they interfere in government affairs, but they can even point fingers at the appointment of the emperor.

.......

"This is a new pavilion that I have built, there are usually no people here, there are rockeries on three sides, I can sit here and enjoy a moment of leisure..."

Liu Bang strode on the gravel path, and when he was a little tired, he simply took off his shoes and walked barefoot, while beside him was a middle-aged man with a cold face. The two of them walked on this path one after the other, and not far away, there was a group of armor soldiers, staring coldly here.

The middle-aged man's eyebrows were upturned, which made him look strong, even a little scary, while he was thin and his skeleton was not small, he was dressed quite plainly, and he followed behind Liu Bang steadily.

"Why don't you speak? Here, we are not monarchs and ministers, just friends, don't be as restrained as the court. ”

Liu Bang buckled the soles of his feet and said with a grin.

"Since it's a gathering of friends, why are there so many elite armorers behind you?"

"You're wrong about me, I'm walking with a tiger, how dare those armorers relax?"

The middle-aged man suddenly laughed, laughed for a moment, and then stopped abruptly.

"What do you think of this person?"

"Loyal and brave, mighty, a good pioneer, but not qualified to be a general."

"Then what do you think of Cao Shen?"

"Obedient, can execute orders well, but has no own opinions, can break the enemy but can't lead the army."
