The fine iron turned into knife tires was continuously transported to the rear through the chute. Qin Long did not guide it manually this time. Instead, he hung the new knife tires on the chute and squeezed those old friends into the next furnace.

.

The furnace in front of Qin Long was different from others. There were two pairs of blowing flints engraved on the furnace. When the fire was fully turned on, the refining speed was so fast that it took off.

It didn't take long for the fine iron in the furnace to be discharged into a long queue and the annealing process began.

"Is this considered weapon refining?" Yan Yuan felt bad looking at this scene.

He never expected that Qin Long could play so many tricks with the stove, and that the chute was actually used like this. What had he made before?

Yan Yuan watched the long river of swords slowly coming through the furnace controlled by several people. He finally understood why Qin Long called this thing an assembly line. It was such an appropriate name. For a moment, he felt that he might be eliminated.

Already.

"No, the quality of such a weapon cannot be guaranteed!"

Yan Yuan doesn't want to just admit defeat. As a weapon refiner, he has his own pride. When refining each weapon, Yan Yuan will pour his heart and soul into it. He can try his best to perfect the shortcomings of the weapon during the refining process and create a new weapon.

To produce better weapons, the assembly line obviously cannot do this.

But when the long river of weapons came to him, Yan Yuan still felt a strong sense of crisis. The quality of those weapons was so good!

If the long knife produced by Qin Long in the experimental stage was defective, then after adjusting the essence film, the current long knife has reached a state of slight defects.

Yan Yuan carefully inspected every long knife that passed in front of him. The surface of the blade was very clean and there were no cracks at all. This shows that as long as there are no problems when these long knives are released, they can reach the level of third-level mid-grade.

It is also the quality of weapons that an average third-level weapon refiner can produce without incident.

Dang.

The first long knife fell to the ground, and the crisp sound attracted everyone's attention. The sun shone on the blade, reflecting a bright light.

"Third-level mid-grade." Yan Yuan recognized the quality of the long sword with just one glance.

Dang clang, clang clang.

In just a moment, a sword hill appeared on the ground, and nearly a hundred identical long knives fell casually to Yan Yuan's feet.

Continuous crisp sounds struck Yan Yuan's soul, and long knives were pushed out from the stove one after another. Middle-grade, medium-grade, all middle-grade weapons.

Yan Yuan went from being shocked at the beginning, doubting his life in the middle stage, to numbness now. It only took Qin Long one time to refine the weapon.

"Assembly line, the word "flowing water" is worthy of its name." Yan Yuan sighed with some disappointment. With this assembly line, there may be no need for weapon refiners like him to exist in the future.

This assembly line is extremely easy to operate. Even those who are not weapon refiners can use it. Wu Jian and Hong Kui know nothing about weapon refinement. As long as they inject spiritual energy into the blowing flint stone, anyone can complete the annealing process. This is a no-brainer.

, you can find any monk who has just established a foundation to replace you.

Yan Yuan's mood fell instantly.

Opposite him was Hong Kui. This guy's eyes were sharp and he was staring at the stove in front of him, watching Qin Long push a long sword that had been forged in front of him.

The interlocking rivers of long knives reminded him of new ideas in his wandering mind.

Seeing the long knives and flames pushing forward one after another, slowly overlapping with the formations and shadows in his mind, Hong Kui suddenly shouted.

"I thought of it, I thought of it!"

With excited roars and crazy dancing, Hong Kui immediately dropped the flint blowing stone in his hand that was infused with spiritual energy and ran quickly to his house.

He finally figured out how to make the formation "see" shadows, which was a major discovery.

As soon as Hong Kui left, the flint blowing stone that lost its supply of spiritual energy immediately shut down. The long knives that were being annealed were also damaged. The temperature dropped suddenly, there was a loud crackling sound, and the solid surface of the knife tires was all broken into ice cracks.

At the end, Yan Yuan felt terribly distressed. He didn't like this thing called the assembly line, but there were more than twenty knives in a furnace. Seeing that the long knives that could have become third-level middle-grade weapons had turned into scrap metal,

It hurts everyone, but it’s all money.

"Hong Kui, what are you doing? Go back quickly!"

Yan Yuan was extremely anxious. If he didn't have to take care of the stove in front of him, he would have wanted to go up and beat Hong Kui down.

"It doesn't matter, let him do it. For people like them, a flash of inspiration means much more than a few swords." Qin Long stopped Yan Yuan.

Without one person, the assembly line could not continue. He took stock of the results of the assembly line's weapon training. In just half a morning, Qin Long had obtained more than a hundred third-level mid-level long knives, plus dozens of second-level low-level knives.

of scrap iron.

This is because the stove Qin Long tried to make was too crude, and it took a lot of time to adjust it. Otherwise, the speed could be much faster. As long as the materials are enough, it can produce as little as one thousand in half a day.

Yan Yuan was completely silent. He looked at the three-level long swords arrayed in front of him and was speechless for a long time. After a while, he said in despair.

"Master...will there be no need for weapon refiners like us to exist in the future?"

Qin Long glanced at him unexpectedly, why did this guy suddenly feel as melancholy as if he had been laid off?

"Are you worried that low-level weapon refiners will be replaced by this industrial assembly line?"

"Industrial assembly line?" Yan Yuan reacted for a moment before understanding what Qin Long was referring to. He nodded and said, "Yes, these long knives... are very good."

It's not very good, but it's great, and it's fast and good. If Hong Kui hadn't left, the knife tires in the previous two furnaces could have been annealed smoothly. Including the previous ones, there would be nearly three hundred.

Of course, in the eyes of a truly high-level weapon refiner, this is nothing. Let a seventh-level weapon refiner refine it, and it may be several times faster than this assembly line, and the quality will be even better.

But who are they? Two slow firemen and two foundation builders. In the eyes of those seventh-level powerful men, they are just rubbish. There are three of them who are soy saucers, and there is only one person who is really busy.

However, just like these four little hotties, they produced nearly 300 guns in half a morning, and each one was a third-level mid-grade product. If such shocking news were released, no one in the entire cultivation world would believe it.

That's three hundred pieces, a quantity that an ordinary third-level weapon refiner would have to work on for more than a month.

Qin Long said with a smile: "No, even if the news spreads through the assembly line, it will not threaten the livelihood of the low-level weapon refiners."

"Why?"

Qin Long pointed to the exhaust port on the top of the stove, "It's simple, because only I can use this thing."

The exhaust port used for cooling is the key to the successful operation of the stove, and if the stove is to ensure exhaust while not exploding, Qinlong's essence film is indispensable.

The essence film is the key to maintaining the stability of the stove. Once this thing is missing, the entire crawler will explode in the next second. Therefore, even if this assembly line is sent to others to copy, they will not be able to copy it, because

This itself is inconsistent with the logic of cultivation.

Not necessarily, maybe Emperor Yuan Tian who also practiced the internal force technique can use it, but he is already an earthly immortal, how can he respect a crawler who produces less than 2,000 weapons a day?

Yanyuan slapped his forehead and suddenly realized that the shock brought by the industrial assembly line was so strong that he even forgot about the exhaust port.

I installed such a thing on the stove just because I didn't want to die quickly enough. I really don't know how the master managed to ensure that the stove was exhausting and not exploding at the same time.

The assembly line looks beautiful, but is actually very incomplete.

The most fatal thing for the assembly line is not the essence film, but the level.

This thing can only produce Tier 3 weapons at best, and perhaps the quality can be higher. By improving the annealing process, it may be possible to mass-produce top Tier 3 weapons, or even fake Tier 4 weapons, but that's the end.

Spiritual weapons of level 4 and above must be carved with formations. Formations are very troublesome. If you make one mistake, the entire weapon will be useless. Moreover, it must be carved during the refining process, and the weapon itself cannot be damaged.

Otherwise, the flow of spiritual energy will be disrupted.

In other words, etching or later engraving is completely unfeasible, so mass production is impossible for Qin Long now. In the future, when he reaches all his cultivation knowledge, he may be able to find a way to do it. This thing can only be used for the time being.

Just to deal with the tasks assigned to him by Shuangyue.

After walking far away from Yanyuan, Qin Long decided to go to his own formation expert to find out what was going on. That was the key to whether he could successfully escape the claws of the "Shadow".

When Hong Kui returned to the house, the door was not closed. The floor was covered with messy papers, most of which were filled with formation diagrams. It looked like a garbage dump at first glance.

Qin Long is a person who has been impacted by the torrent of "artificial genius" and knows that real genius is by no means the kind of being who is meticulous in doing things and has smart reactions.

On the contrary, human beings who can truly be called geniuses, without exception, have some flaws. This is inevitable. People's brains are only that big. If they are not focused, how can they be qualified to be called geniuses?

Carefully avoiding the pieces of paper on the ground, he couldn't understand the array diagrams, but this did not prevent him from recognizing that the lines in some of the drawings were connected. Obviously, there was its own arrangement pattern here, and he did not want to destroy it.

"Why is it so dark in here?"

Qin Long was a little surprised. The decoration style of Hong Kui's house was very unique. Apart from the paper on the ground, the entire interior was charcoal black. It was like there had been an all-round fire, and even there was a faint smell of burning in the air.

"boom!"

While Qin Long was observing, the paper on the ground suddenly caught fire, and a ball of flames burst out from under his feet. The flames came very quickly and swept every corner of the room in an instant.

Qin Long was startled, and knowing that Hong Kui had some bad habits, he quickly summoned a spiritual energy barrier to block the flames. The flames were not strong and the spiritual energy barrier easily blocked them.

"Every time you enter this guy's house, you are opening a blind box!"

He remembered that when he pushed Hong Kui's door, a knife fell off his head. This time, he didn't need to push the door, because Qin Long realized that his door was long gone.

After the flames burned out, the room became even darker. Qin Long finally understood why the place was like this. His feelings had been burned more than once in just a short period of time.

"Hahaha, Lord Molong, I succeeded, I can finally make the formation detect the shadow!"

Before the disgraced Qin Long had time to get angry, Hong Kui walked out of the darkness. When he was about to warn him that experiments should be carried out according to different circumstances, he realized that Hong Kui looked even worse than himself.

At least he reacted quickly and used spiritual energy to protect himself. Hong Kui's eyebrows were swollen a lot, and his chest was dark. It looked like he was laying out paper in the room at that time, and he happened to come in for some reason.

So I activated the formation, but this kid was tricked.

Qin Long was a little embarrassed and couldn't say the words of warning, so he changed the subject and said: "How did you say you can make the formation recognize shadows?"

Hong Kui excitedly took out a piece of paper from the space bag. It looked similar to the papers on the ground before, with lots of drawings on it.

"Look, my lord."

He stretched out his hand and waved it on the paper, and the shadow of his palm cast by the sunlight suddenly appeared on the white paper.

"Boom..." The moment the shadow crossed, the white paper burned.

"What the hell, are you so powerful?" Junqu Pavilion
