The craftsmen saw Ye Yu driving the car out very skillfully, and their eyes were full of surprise and reverence!

The speed is not fast, but it is quite easy to look at Ye Yu's appearance.

"First loosen the soil, remove the plough and replace it with a shovel with serrated teeth."

Ye Yu said as he removed the curved plough and replaced it with a serrated shovel to loosen the soil.

The craftsmen looked incredulous.

Detachable heads, they can think of them.

They really didn't expect to be able to pick up the car.

Ye Yu drove the car, controlled the steering wheel, and used the car to slide around on the mound of dirt very easily.

Although no results were seen, they were able to imagine.

Ploughing can be done by one person, even with ease, and the value of agriculture is immeasurable.

"You can try it yourself."

Ye Yu said, let these craftsmen try to use this small cart to plow the land.

The craftsmen tried it out.

Using such a tool is really effortless.

"Your Highness, if such a strange thing can be popularized among the people...... The future is limitless! ”

A group of craftsmen, so sighed.

It didn't take long for Zhao Wanjin to be called to the scene with a few waiters from the household department.

"Zhao Wanjin, thank you for your hard work, this is the latest farm tool."

"Farm implements?"

Zhao Wanjin looked at the cart and the craftsman's expression at the beginning was as puzzled.

Except for the shovel and plough on the side, he really couldn't tell that the cart was a farm implement.

"It's been tested, and there's nothing wrong with it."

Ye Yu said, and ordered a craftsman to go up and demonstrate to Zhao Wanjin.

The shovel and the zigzag plough dragged behind the trolley easily moved back and forth on the soft soil.

Seeing this scene, Zhao Wanjin was surprised.

"Your Highness, who designed this?"

"It's really unprecedented!"

Surprised, Zhao Wanjin sighed.

"I designed it, and I thought of it when I went to bed at night."

Ye Yu smiled easily.

It did take him a little time.

After all, there is no other power to exist, and only the most primitive human and animal power can be used.

Then the power mode and labor-saving lever of the bike are the absolute core.

Combined with the current carriage, he designed this kind of thing, which even the ancient times of his previous life did not have.

"Temple...... Your Highness ......"

Zhao Wanjin was speechless, only amazement in his heart.

"I plan to spread these tools to farmers around the capital before sowing seeds."

Seeing that Zhao Wanjin was slightly relieved, Ye Yu spoke.

"Your Highness, I'm afraid this car isn't cheap, right?"

Zhao Wanjin said, "If farmers want to afford it, I'm afraid it ...... Only rich peasants over 100 acres can use it......"

"The structure of this thing is convenient and firm."

"You don't need a lot of wood or ore to build one."

The craftsman explained.

"What I have designed is naturally affordable for ordinary people."

"Zhao Wanjin, you send someone to preside over this matter, and all these cars will be given to the farmers."

Ye Yu thought about it and said, "Then, with the extra money, buy the cattle in the hands of the farmers, find a piece of land, and specialize in raising cattle and making jerky." ”

"Send?"

Zhao Wanjin was a little surprised, "Buy the cattle in the hands of the farmers...... It's also a lot of money...... I'm afraid ......"

"Isn't there enough treasury now?"

Ye Yu frowned slightly.

"Enough, but in the long run, I'm afraid the treasury will be depleted."

Zhao Wanjin said.

"The peasants have better tools and better harvests, and won't the entire Southern Dynasty benefit in the future?"

Ye Yu retorted, "This is just one of them, there will be no shortage of money." ”

With his words, Zhao Wanjin breathed a sigh of relief, bowed his head and arched his hand, "Chen, let's do it!" ”

It didn't take long for a few servants in the household department to learn how to use farm carts and how to disassemble and assemble different tools.

"By the way, this place will be called the craftsman office in the future, and let Zhou Hao, the official, assign it."

Ye Yu said, hurriedly walking to another place.

It was filled with smoke and the sound of explosions was incessant.

The venue is not very large, but a large number of warlocks are discussing with each other.

"I said I should add a little more sulfur!"

"No, adding more sulfur is slow!"

"Won't you listen to me and break them to pieces a little more?"

The discussion among the warlocks was intense. The Dan furnace has blown up quite a bit.

The blasted furnace was sent to craftsmen and blacksmiths, melted and remanufactured.

Although a lot of wood was consumed, the total amount of Dan furnace remained the same.

"How's the research going?"

Ye Yu listened for a while, waited until the warlocks were a little quieter, and then asked.

"See Your Highness!"

All the warlocks had satisfied smiles on their faces.

"Your Highness, we can basically determine that saltpeter and sulfur can explode according to different proportions."

"However, the dosage formula still needs to be refined."

One of the older warlocks replied.

It seems that he has basically become the "leader" of these warlocks.

After some discussion, Ye Yu knew that they had basically mastered the formula of black powder.

Although this is still too primitive compared to the smokeless gunpowder of the future, it can be used.

"Yes, but what about the thing that can blow up when you fall?"

Ye Yu nodded and continued to ask.

"Your Majesty, this is a bit difficult, we have found a lot of materials, but we can't achieve it."

The elder warlock explained.

"Okay, you take your time."

Ye Yu raised his hand to let everyone relax, "This fried pill recipe is called gunpowder for the time being." You have made the recipe for the best effect of gunpowder. Get this done first. ”

With that, he nodded and left.

There have been advances in farm tools and gunpowder, but the only pity is that gunpowder has not been studied.

When he thought of his trip to Xishan Prefecture, a bad premonition suddenly popped up in his heart.

I always feel that Xishan Prefecture is very dangerous.

Prevention is better than prevention, and he must be prepared.

Back in the study, I wrote hard and began to draw on a few pieces of paper.

After a while, the blueprints for the short handcuffs and flintlock pistols appeared.

At the current industrial level, it can only do such things.

"Your Highness, I'm back."

Pretending to be a eunuch's henchman, he walked in quietly, and even Ye Yudu didn't notice it.

"How's Ling'er's matter?"

"There are indeed a lot of checkpoints on the road."

The henchman replied, "I have already commanded Princess Gongsun, and I would rather seek stability than speed." ”

Hearing this, Ye Yu nodded.

"I'm going to go to Xishan State."

He spoke slowly.

"Your Highness, my hometown is in Xishan Prefecture, and I can guide Your Highness."

The henchman replied, "But there are some dangers in Xishan Prefecture. ”

"What do you mean by that?"

His words confirmed Ye Yu's premonition.

"Xishan Prefecture is in the mountains to the west, and most of it is in the mountains."

"The transportation is inconvenient, and a lot of news can't be conveyed anywhere."

The henchman guard said, his brow furrowed slightly.

"I see, you go and prepare first."

Ye Yu said, stretched his waist, and suddenly felt sleepy.

After a busy day, my spirit is a little scattered.

A few days later in the night.

"Your Highness, it's not good!"
