Shiyu City is operating in an orderly manner.

After temporarily solving the big problem of Medicine King, Qin Long finally had some time.

He had already asked Shuangyue to find someone to investigate the "Shadow", but the other party came and went without a trace, and he had no good countermeasures for a while, so he had to concentrate on building defenses and doing research and development at the same time.

After being blown up by Little Sun, there was really nothing left in Shiyu City now. Shi Kai was so busy that he didn't know where to start.

After discussing with Shuangyue for a long time, a detailed recovery plan was formulated. The plan was very simple to implement, using cultivation resources and gold coins in exchange for the labor of the monks.

When they landed on the ground, Shuangyue naturally found Qin Long and asked him to help provide weapons for the Li family.

Logically speaking, this is not a problem.

There were too many demon wolves. Only most of those close to the city wall were killed, and a small number escaped. Now those demon wolves are scattered in the mountains and forests, waiting for opportunities to kill passing monks. They were afraid of being blown up by the little sun and did not dare to attack Shiyu City again. Continue

This can be easily solved by exchanging wolf bones for bone soldiers.

However, the weapons this time can no longer be replenished with bone soldiers. Weapons that are truly refined from refined iron are needed. Only in this way can we drive supply and sales and reactivate Shiyu City's transportation lines.

Qin Long was in trouble. If it were a bone soldier, he could easily complete the task with his level, but how could he have the time as a savage to practice ordinary weapons now, and he could only focus on finding ways to improve his cultivation.

But Shuang Yue and Shi Kai had to help because they were the only thugs he could hire, so he couldn't ruin his relationship with them.

Try to use internal energy to refine refined iron. The level of internal energy is too high, and all the refined iron you get will be wasted. If you want to produce a better finished product, you can only rely on the furnace.

"It's too much trouble."

He threw the newly refined third-level long sword into the pile of swords aside and rubbed his sore wrist.

The capacity of the furnace is limited, and you can only refine two long knives at most at one time. You must not make a single mistake in making a real long knife from a fine iron block, otherwise the quality will be reduced.

He tried to refine a hundred weapons, but it actually took him nearly two hours. This was already a very short time, and Hui Yanyuan probably wouldn't be able to refine even half of the number.

"Every time you form an army, you have to evacuate it. This is the biggest waste of time."

The refined iron was very fragile after being refined and had to be annealed before it could be stabilized to a better quality. He wished he could make the furnace as big as a house and refine a hundred handfuls at a time.

But that was impossible. Even if he could build such a large furnace, he would not be able to find so many flint stones at the same time.

"By the way, I almost forgot about this."

During the black market battle, after the fall of Luo Yutian, all the things belonging to the Luo family belonged to Qin Long. At that time, he had no time to collect those things, so he put them all with Wu Jian, plus there were a lot of flint stones he had purchased before.

When he first collected these flint stones, Qin Long wanted to imitate the industrial assembly line and create a workshop that could quickly refine weapons in the world of cultivation.

A fully automatic one is definitely not possible, but a semi-automatic assembly line with manual participation might be feasible.

The idea is actually very simple. First make a large rectangular stove, install the flint blowing stones on both sides of the stove, and several people can control the flint blowing stones to release flames to form different temperature zones. The temperature zones overlap with each other, so that you can form a

The cooling channel allows the refined blade tires to slowly anneal. The process can be said to be quite brainless.

No brains, no brains. As long as it works, Qin Long is happy to be more brainless, but this kind of furnace requires a lot of manpower. He only has three people under his command to use it. He is still the main force in refining weapons, so he can't take care of it.

Therefore, Qin Long could only make a simple version of the assembly line, with the same number of people and the same stove, but with a few more layers of essence film added.

"Master, is this the assembly line you are talking about?"

The stove placed in the courtyard is huge and ugly. With Yan Yuan's aesthetics and Qin Long's own filter, he can't say anything to boast about it.

It's so ugly, it's no different from a crawler. The arched furnace body is really like a dead crawler, with all four legs in the air.

Not only did Yan Yuan not see it, but Qin Long himself felt ugly.

This assembly line was pieced together by him. Many of the details were left untouched. He simply searched out some intact stoves from the city and moved them over directly. He put the two sides of the stove on the ground and pushed them together to complete it. The air leakage was due to

Don't be afraid, the membrane of his essence cannot block the source fire, but it is still easy to block the blowing flint.

Qin Long also had his own ideas for the inversion.

In normal weapon smelting, in order to make the texture of the long knife more uniform, the weapon smelter needs to use spiritual energy to smelt it in the air. It is unwise to waste time and spiritual energy.

Now in order to ensure quality and quantity and rapid production, this is naturally the first aspect to be solved. Qin Long installed two rail chutes at the bottom of those inverted stoves.

He asked Shuangyue to refine these two chutes out of refined copper. The quality of the fourth-grade low-grade materials allowed those flint stones to remain in shape even after being burned for a year.

With the chute, whether you are refining a knife or a sword, you will always hang it while refining, saving spiritual energy and space. During the annealing process, you only need to use spiritual energy to move it along the chute, which is very convenient.

"It does look a bit ugly, but this is only temporary. Functionality is the right way to go. We can slowly modify the appearance."

Instruct everyone to stand in position and start the flint blowing stone, throw a few pieces of fine iron into the furnace and start refining immediately.

In the refining process, melting the fine iron is the easiest step. You only need to use enough spiritual energy to activate the flint stone. The difficult part is to remove the flame.

Because of the lack of manpower, Qin Long could only let Yan Yuan and the others control the two stoves. He was not required to control the blowing fire stone. He only needed to pour all the spiritual energy into it. He was responsible for adjusting it with the essence barrier.

Thin layers of energy barriers separated them from the connection between each stove. This was a barrier specially set up by Qin Long to prevent the flames from flowing around.

The following furnaces needed to be annealed, so Qin Long specially opened the exhaust vents, and streams of red light continued to spurt out from the crawler's joints.

In an instant, the crawler with its legs in the air changed its appearance, its whole body glowed with white and red light, and it looked like it was about to explode.

Hong Kui didn't know how to refine weapons, so when he saw those flames, he thought it was a normal situation. He only needed to pour spiritual energy into the furnace, and even watched it leisurely for a while.

Yan Yuan is different. He is a weapon refiner, or one who has been given a title in the black market. His basic knowledge is extremely solid. Gas leakage in the furnace during the refinery is a very serious situation, which will cause the furnace to explode.

.

"Master! This stove has a leak!"

Qin Long didn't look back: "Don't worry, this is a function I specially changed to cool down."

"But the stove will explode!"

Yan Yuan reminded loudly, hoping Qin Long would pay attention to this situation.

The power of a furnace explosion is no small matter. If nothing else is mentioned, nine out of ten of the weapon refiners working in front of the furnace will be unlucky. Even if they are lucky enough to survive, they will be disabled. The most important thing is that the furnace is in front of him.

Although the one next to him also leaked air, the one who controlled it was a sword. It was unlikely that the furnace would hurt anyone when it exploded. Why was he so unlucky?

Wu Jian also felt guilty. When he saw the flames spraying out, he just felt something was wrong at first. He instinctively felt that it was dangerous, but he didn't take it too seriously.

He knew that his nephew was a weapon refiner and could make pseudo-fourth-level spiritual weapons. He was a very powerful weapon refiner. Since he said it was okay, it should be true.

But when Yanyuan shouted the word "explosion", Wu Jian became worried.

Yes, it is true that Qin Long is a weapon refiner, but that does not mean that there will be no problems with the stove, because he has personally seen Qin Long's weapon refinement and frying pot, and the power is really fierce.

Wu Jian quietly used his spiritual energy to erect a barrier in front of him to prevent the stove from suddenly exploding and leaving him no time to react.

Yan Yuan is even more worried now. Look, your uncle doesn’t believe you!

Qin Long didn't care. He used his energy to control every bit of heat flowing from these stoves. Those membranes were much stronger than the stoves.

Under his control, the fine iron quickly turned into a knife. Different from other long knives, this knife has an extra ring on the handle. This is the place to hang the knife. With a gentle movement of spiritual energy,

, the knife tire moved slowly along the chute and came to the furnace in charge of Hong Kui to start the preliminary annealing process.

"Hey, you can still do this?"

Yan Yuan in the distance didn't understand the function of those hooks just now, but now he suddenly understood after seeing Qin Long's operation.

"It is indeed a good idea. Installing such a thing can eliminate the need for spiritual energy to lift the blade, avoid a lot of unnecessary consumption, and occupy much less space. You can refine several weapons at the same time."

Seeing Hunter's eagerness, Yan Yuan temporarily forgot about the fear caused by the leaky stove. He stretched his neck and looked ahead, half expecting the knife tire to turn in front of him soon.

After several times of obstruction by the essence film, the color of the knife tire was finally no longer bright, and it was already at the last moment when it turned to Yanyuan's side.

The flame sprayed from the exhaust port of the furnace in front of him was the longest, and the temperature inside the furnace was also the lowest. When the knife tire crossed the essence film, the temperature difference was a bit large, and a layer of fine patterns appeared on the surface. Yan Yuan could even hear the steel being torn apart.

sound.

Judging from the light color on the blade, this long knife is of the middle grade of the third level. If it is broken into pieces, it is directly downgraded. Now it is made of the material of the low grade of the third level at most, and it may become the second level.

After taking out the long knife, Yan Yuan confirmed his judgment that it was indeed a third-level low-grade sword.

Qin Long was not surprised by this. This was originally a test product. He deliberately increased the temperature difference between the furnace and the furnace so that he could intuitively judge the annealing condition of the weapon. He was surprised to get a low-quality product.

They are all ready to get the second-level weapons.

"Ruined..."

Yan Yuan was a little distressed, so he dispatched four monks and wasted so much effort to refine a third-level low-grade weapon.

"Don't be discouraged. The significance of the assembly line is speed, not quality." Qin Long advised.

Yan Yuan didn't say anything, but he still felt regretful in his heart. With this efficiency and quality, it would be better to let him practice alone. At least he could keep the middle grade, and the speed wasn't much faster.

Seeing that Yan Yuan didn't say anything, he knew that he was not convinced. This guy was very proud of the weapon refining, and Qin Long didn't intend to explain. Everything should be based on facts. Wait, let this kid see what the three words "assembly line" carry.

the true meaning of.

Instructing everyone not to lose their spiritual energy, he took out a pile of fine iron from the space bag and threw it directly into the furnace, almost blocking the furnace.

Glancing at Yan Yuan who was absent-mindedly at the end, Qin Long became excited and said, "Haha, Yan Yuan, let's feel the horror brought by industry."
