Hundreds of people coordinated the work, coupled with Ye Fan's superb ability, the blacksmith shop was ready in just three days.

Unfortunately, he only has the chakra of Hashirama Senju, and does not know how to use the wood escape ninjutsu. He can only make the trees grow wildly and there is no way to grow a house in one trick. But even so, Ye Fan was satisfied with this speed.

There is a circle of fences ten miles east of the village, and there are two thatched huts adobe houses. On one side of the thatched hut is a long shed, which contains stoves, pools, bells, etc. built by blacksmith Li Tu personally guided.

This is just a very simple blacksmith shop. This shop cannot refine iron ore into pig iron, and cannot mass-produce high-end things. It can only temper the purified iron materials into the desired shape, such as agricultural tools, weapons, etc.

But even so, it is a brand new starting point, a very good starting point.

"Li Tu, now the blacksmith shop has been prepared for you. Can you create something?" Ye Fan asked, looking at Li Tu, who was surrounded by the stove, with a happy face and shirtless face.

"Your Majesty the Emperor of Heaven, please give me instructions, I will build it for you immediately." Li Tu replied immediately.

"This is my newly designed tool, shovel, see if it can be created."

Ye Fan directly drew the sharp-mouthed shovel in his memory with branches on the ground. After observing Zhang Mutou and others working these days, Ye Fan found that many tools in this era are made of wood, and the shape is very different from that in modern times, and the efficiency is very low.

It affects the progress of the project.

Therefore, since he can be forged, he must create some common tools in life, such as shovels and saws.

"The front part is forged with iron. The sharp mouth of the shovel should be sharp and the shoulders should be blunt, so that people can trample their strength with their feet. The same part on the shoulders is used to connect the wooden pole to the shovel handle. When the wooden pole is inserted and fixed, it will be a complete shovel. How about it? Is there any problem?"

Looking at the gestures and explanations of the branches in Ye Fan's hand, Li Tu quickly understood, but there was a place that still didn't quite understand. "Your Majesty, the general small ones have already understood that such forging is not difficult, but... Are the few small holes you left in this iron neck for inserting the wood tips?"

"This type of iron tool is connected to a wooden pole, and the wooden pin may not be easy to use."

He looked up at Ye Fan, and Li Tu carefully reminded Ye Fan.

"Then have you ever shot something similar? For example, how do you fix the spear head and gun rod?" Ye Fan asked back without directly answering Li Tu's question.

"Your Majesty Huitian Emperor, the young man had fired a spear for someone. Before inserting the spear head, burn the spear head red, and then directly insert the prepared spear head. When the spear head cools down, it can become one." Li Tu said quickly.

Hearing Li Tu's words, Ye Fan nodded slightly, understanding that this was the principle of thermal expansion and contraction, but...

"Your method is not impossible. It's just that guns and spears are used for fighting. The operation method is different from labor tools. If you shovel the soil and dig the ground with shovels, if you just use your method to fix it and use it over time over time, it will probably not take long for the shovel head and shovel rod to separate."

After touching his chin, Ye Fan picked up a stone, then his palm condensed Susan's black knife, and the black knife that cuts iron like mud quickly carved the stone like cutting tofu.

Soon, a straight stone nail, a rough but clearly combination of stone screws and screwdrivers appeared in Ye Fan's hands.

The nails are very simple, just a round cap is enough, but the screws and screwdrivers are not simple. In order to reduce the difficulty of forging, what Ye Fan made was not a cross screw, but a flat screw. The screwdriver was not a rubber or wood handle. The handle part was changed to a triangle, which could better borrow strength.

Otherwise, fixing the screwdriver handle and the screwdriver body will be another problem.

The technology is too different in all aspects, so we can only use other methods to replace it.

"This is the iron nail, screw and screwdriver invented by this seat. The specific usage is like this. Can you build it?"

While speaking, Ye Fan personally demonstrated the usage of the three.

Pick up two wooden boards and nail them directly into the stone nails.

I picked up two thin-plate wood and then tightened the screws directly with a screwdriver to fix it. Although the screws made of stone and screwdriver are not easy to use, the principle works.

Soon, two thin wooden boards were fixed.

There are technology from this era, and mortise and tenon technology is also easy to use, but mortise and tenon technology is limited and the efficiency is not high, and it is not suitable for all occasions. Therefore, Ye Fan decided to get iron nails and screws.

In fact, for fixing shovels, iron nails are enough, but since you have done them all, let’s try them together. If you really need to get the screws out, it will be enough to overturn many things.

Li Tu was not surprised by the iron nail. Although it was different, there were already iron nails in this era, but the structure was different. The nail cap was not a round plane but a one-way single-line shape. In addition, due to the difficulty of forging, it was basically not necessary, or wooden nails were used instead.

But screws and screwdrivers...

Looking at the thin wooden board fixed by screws that Ye Fan placed in his hand, Li Tu's eyes flashed with curiosity and surprise. He had never used such a fixing method before.

"You can use a screwdriver to unscrew it in the reverse direction first."

Seeing Li Tu rummaging and turning, Ye Fan handed him the stone screwdriver and signaled him how to screw out the screws.

It was made of stone and was very rough. Li Tu was a little strenuous in unscrewing the screws, but this did not prevent him from being surprised by this thing.

"What a good thing. With this thing, you can save a lot of trouble."

"So, can it be done?"

After Li Tu understood the stone screws and screwdriver, Ye Fan asked.

He doubted the technology of this era. Without turning and processing, the difficulty of producing screws depends entirely on mold control, so it is definitely not that easy.

Rubbing the thread on the screw, Li Tu pondered slightly, then nodded heavily, "The mold of the iron nail is not easy to make, but it should be able to make it. As for Your Majesty's screw, I'm afraid..."

He has been working on iron for decades. Although he has only made simple farm tools and the like, Li Tu is also very experienced. He knows the difficulty of making those circles of threads.

At least, he knew that he didn't have that ability.

"First forge the iron nails. As for the screws, I will cooperate with you. If it can be done, I will reward you as a woman." Ye Fan promised.

"Don't worry, His Majesty the Emperor of Heaven, he even tried his best to get this thing out!"

When Li Tu heard the woman, his eyes shone.

Nodding slightly, Ye Fan said again, "In addition, you need an apprentice and need to teach more blacksmiths."

"I understand your thoughts and teach your disciples to starve your master to death. Craftsmanship should not be passed on lightly, but what I want to tell you is that even if your disciples do not remember your master's kindness, I will remember your merits."

"No matter what your apprentice is, if you bring out an apprentice, I will remember your achievements. I understand?"

The treasure of one's own craft is passed down to children and grandchildren. In this era or the entire feudal society attaches great importance to the craft that can make oneself eat. Ye Fan understands this, but it must be broken!

Technology cannot be popularized and is always limited to the hands of a few people. This will lead to a sluggish development for both society and technology itself.

This is definitely not what Ye Fan wants to see.

"Don't worry, Your Majesty, I must have taught my apprentice with all my heart, but now we don't seem to be anyone."

Li Tu would question ordinary powerful people, but he had no tricks to Ye Fan and Li Tu, and his absolute strength brought absolute obedience.

"You don't have to worry about people. After you go back, I will screen the apprentice and you will choose again."

Ye Fan said slowly, "In addition, this blacksmith shop is still too small. I will bring back more blacksmiths in the future, so it will expand here."

"And don't think about the miscellaneous things. Forge the things I gave to you in peace and forge them well, that's what you should do."

"I understand!" Li Tu responded quickly.

"Then start forging. I want to see how you forged it. With me here, some special things that are difficult to make should be easier to do."
