Hine took Chen Nai and went shopping for his own guy.

With Hine's internal staff to help with procurement, the price is naturally cost, cheap and affordable, and the quality is guaranteed.

After the material procurement was completed, when he came out, Hein also met a person, Hemingway.

I haven't seen him for a long time, and Hemingway habitually comes up to mock it.

"I heard that you went on a long trip, but you didn't die outside, your life is quite hard, a cheap seed is a cheap seed."

In the face of such a cordial greeting, Hine didn't say anything, didn't even look at it, and just walked past him.

This is ignorance, the ignorance of Chi Guoguo.

This attitude of ignoring made Hemingway very angry, and he couldn't get angry, so he raised his palm and slapped the back of Hein's head.

In this regard, Hine is just running the magic power, the magic power of the holy light attribute, emitting a milky white light, blooming on the surface of Hine's body, forming a layer of light.

This layer of light looks very fragile, but it is enough to defend against Hemingway's slap.

The familiar magic, and this magic outward, although Hine did not say a word, not even a word, but his actions had undoubtedly told everyone that he had recovered.

"You, you're recovered?"

slapped down, the other party didn't do anything, but his hand was a little numb.

But Hemingway no longer feels it, and his biggest feeling now is shock.

The genius he used to be is back.

Then his status will not become a younger brother, he will be a younger brother.

Hine still didn't say anything, as if he hadn't seen Hemingway at all, and left the family shop.

"Why would you deliberately ignore him?"

Well, it's deliberate, Chen Nai sees this very clearly.

Hine shrugged and said: "After all, he is my brother, and I can't do anything to him, and it is not my character to retaliate back arrogantly, so ignoring him is the best choice." In this way, he will be terrified, and whenever he meets me, he will walk around me. ”

"Hey, I didn't expect you to be quite black-bellied!"

"Black-bellied, maybe."

For this evaluation, Hine is noncommittal, and his belly is black.

After having sufficient materials, Chen Nai began to enter his forging plan, the forging diagram is available, and the raw materials are also available, but there are several things that need to be processed to meet the needs of the forging diagram.

Among them, the most headache for Chen Nai is the spring.

A spring is a kind of mechanical parts that use elasticity to work, and the parts made of elastic materials are deformed under the action of external force, and then return to their original shape after removing the external force.

In today's machinery, it is important to use the spring as a buffer in many places, so as to protect the machinery from damage and prolong the service life of the machine.

From the structural point of view, the spring is not complicated, it is just a simple spiral.

However, its process is not simple, and the materials required are also very particular, such as iron and copper, which have insufficient hardness and toughness, are not suitable for making springs.

It is generally made of spring steel, although we generally say steel, but steel is actually an iron-carbon alloy, and iron is only its main element.

Although steel is also made from iron, there is a fundamental difference between the two, and it is not a joke to be made into steel.

Iron ore, iron blocks, these things, Chen Nai has on hand, but if you want to forge into steel, you need to fill with some other ingredients, this is a very troublesome and complicated process, Chen Nai's forging skills are completely useless.

"Tut-tut, I don't have a spring in my backpack, and the blacksmith of this world doesn't seem to have trained the craft of steel, it's really troublesome."

Chen Nai was very distressed, so distressed that a lot of hair fell out.

"Master Cat, is this little thing with a spring really that important?"

Eddie said he didn't understand why this little thing was so important.

To be honest, even if you don't add this thing, it won't have much impact on the use of the whole weapon.

"Of course it's important, if you don't have this thing, this weapon will be forged, and it won't be used a few times, and it will be scrapped, and it can even be said to be a disposable."

Suddenly, Chen Nai thought of something.

The little thing of the spring, indeed, seemingly, probably, may ...... No, you don't.

If you want to say why, because this is a magical world, magic work is completely different from mechanical work, as long as you can control the magic well, then you don't need to think about the buffer problem at all.

Therefore, from the very beginning, Chen Nai fell into a misunderstanding.

"Add, you can draw the forging diagram you gave me again."

"Yes, Master Cat!"

Although the original drawing of the forging diagram has been studied by Chen Nai, it was drawn by Eddie, and it is still deeply imprinted in his mind, and it is impossible to forget it.

It didn't take long for the forging diagram to be drawn.

Chen Nai pointed to a few places and said, "Come, let me tell you my request, first of all, remove these small parts." ”

Originally, I also needed some special small parts, which were more difficult to get, but they were not impossible.

But now Chen Nai has completely given it up, because this is a magical world, a problem that can be solved with magic, why bother to get closer to physics.

Newton's hand couldn't stretch that long, and he didn't care about the world.

What's more, this is a forging diagram, as long as the system judges that the forging diagram is successful, and you can learn it into the list to meet the needs of the material, you can forge it.

As for other follow-up questions, there was no need for Chen Nai to care about it at all, after all, it was difficult for him to explain and understand the skill of forging, let alone the system.

If the system is famous, it must be a high-quality product.

Don't ask so much, there is only one thing you have to do, just meet the conditions of the system.

In this way, Eddie, at the request of Chen Nai, made some changes to the forging diagram.

Although it is just a modification to remove unnecessary small parts, it is also a big project for Eddie.

Originally, he didn't know much about the principle of this weapon, and he didn't know the role of these parts very well, and after losing these parts, he had to use what he had learned to improve this forging diagram, so that this weapon could really be put into use.

Originally, this was a problem, but it seemed that because of wearing a hard hat, Eddie was Lingquan Siyong, and it took one night to overcome all the problems and complete Chen Nai's requirements.
