Not to mention that Xiao Hei sighed there, Qin Yu returned to the Thunder Mountain Residence Refining Room.

Originally, there was only one gossip furnace in this refining room. Later, Qin Yu refined a set of forging tools and placed them in the refining room. As a result, the refining room is a little crowded.

However, Qin Yu couldn't help it. These utensils are only suitable if they are placed here.

This set of forging tools was of course refined by Qin Yu using the refining method of the cultivation realm. And all of them are made of high-quality spars. Therefore, this set of instruments is all high-grade spiritual weapons. It's just that these high-grade spiritual weapons are not used to attack.

Immediately, Qin Yu took out a few pieces of low-grade spars, and then the cyan flames were suddenly generated in the furnace, and then, Qin Yu threw the spars into the furnace and began to smelt them.

Slowly, a tinkling sound sounded, and Qin Yu finally used his Thousand Hammers to forge a spar.

Gradually, a sword-shaped embryo was produced in Qin Yu's hand. And at this time, the dinging sound continued.

Finally, the forging sound came to an abrupt end, and a perfect embryo was formed, and in an instant, the embryo fell into the blue cold spiritual water. Quenching starts.

It's just that he used the mortal iron of the mortal world to refine weapons before, so he has no experience in quenching the spirit weapons cast by the spar, and he can only rely on the reaction of the spiritual sense.

I saw that the spirit sword embryo was "sneering" in the cold spirit water, and the quenching was proceeding slowly.

Under the induction of Qin Yu's soul power, this long sword was slowly becoming sharp and tough. The state of the longsword gradually increases.

However, embryo quenching is like a projectile that descends when it reaches the top. Moreover, the state of this weapon is not slowly declining, but at the moment of its peak, it is rapidly declining.

At this time, this was the case with this long sword, at the moment when the state of the long sword reached its peak, it suddenly dropped, although Qin Yu's main soul reacted quickly and quickly fished out the long sword, but it still made the state of the long sword drop a lot.

However, Qin Yu didn't have time to pay attention to these at the moment, only to see Qin Yu's hands flashing, and one formation after another was arranged by Qin Yu on top of the long sword. An hour later, the formation was arranged. This long sword has finally been successfully refined.

Qin Yu looked at the long sword in his hand and nodded slightly, "It's not bad, it has reached the level of a medium-grade spiritual weapon, and it is also a medium-grade spiritual weapon that can be called the pinnacle." If the quenching is more perfect, it should be a high-grade spiritual weapon. It seems that the theory of using the method of forging to refine spiritual weapons is feasible. ”

This was the first time that Qin Yu had used a spar to refine a spiritual weapon through the method of forging. Of course, there will be some mistakes due to lack of experience. However, the results are gratifying.

It is of course feasible to use the low-grade spar to refine a medium-grade spiritual weapon, and to use the refining method of the cultivation realm. It's just that even if it succeeds, it's just a low-grade or medium-grade spiritual weapon. And it is impossible to refine a peak mid-grade spiritual weapon.

And Qin Yu forged the lower-grade spar into a pinnacle middle-grade spirit weapon through the method of forging, which was a miracle in itself.

Because this affirms that the theory guessed by Qin Yu is correct.

As long as the theory is correct, and then it is tested, success is inevitable.

That's why Qin Yu is so happy.

You must know that since the low-grade spar can refine the high-grade spiritual weapon, the medium-grade spar can of course refine the top-grade spiritual weapon.

What about the high-grade spars? Is it possible to refine a low-grade immortal weapon? Even if the top-grade spar can't, the possibility of refining the immortal weapon from the top-grade spar is definitely not small.

Although there is no primordial spirit qi in the best spar, the spirit is equivalent to giving the weapon soul. Can't a soul weapon absorb the energy of the primordial spirit from between heaven and earth?

Of course, this is all speculation, and the exact way to do it needs to be tested. However, before experimenting, it is important to accumulate enough experience.

"Although a medium-grade spiritual weapon has been refined, it is obviously still a little insufficient. Especially when quenching, because of the lack of experience, the quality of the long sword has dropped a lot. It seems that a lot of effort should be made to accumulate experience in quenching. And it's not perfect, and there's still a lot of room for improvement. Qin Yu began to summarize the shortcomings of this refining. If you want to improve, you can't do it without summarizing and reflecting. Only by finding your own problems can you keep improving, otherwise you can only stop forever.

"Of course, the formation needs to be further studied. After all, this is related to the merits of the Enlightenment, and the merits of the Enlightenment are also related to the ultimate quality of the weapon, and it is not to be sloppy at all. It's just that the study of this formation has to be considered in the long run. Qin Yu thought to himself.

Qin Yu really wanted to study the formation, but he couldn't continue to study the formation, not because he didn't have time, but because he didn't have the cheats.

He had already studied all the formation cheats in his hand, and he thought of studying the formation further, unless he got a new formation book.

But where did he go to find the formation book now? It's not something you'll find in a moment. That would at least be after he gained a foothold in the cultivation realm.

Of course, if Qin Yu insisted on studying the formation, of course he could. Learn from the past! But it's not worth it.

This is like learning the knowledge of primary school, but there is no textbook for junior high school, we can study the knowledge of junior high school through the knowledge learned in primary school. But this kind of research is very time-consuming and does not pay off. If you can get junior high school textbooks to study, why waste time and energy on research? This is the case with Qin Yu now.

Qin Yu could study new formation knowledge based on the formation knowledge he had mastered. But he wasn't so stupid.

Thinking about Xiang Yang's high talent, more than a thousand years have only studied the cultivation method of the Yuan Infant Stage. If he has a ready-made cultivation method, it is estimated that he will have the strength to cross the tribulation period. It can be seen how stupid he is despite his high talent.

Is Qin Yu so stupid?

"It's good to start over." Qin Yu, who had figured out all the crux of the matter, put away his long sword, and then took out a few low-grade spars and started a new round of attempts.

At this time, Xiao Hei was watching quietly from the side. He's just so boring. In terms of cultivation, he has already reached the peak of the Yuan Infant Stage, and he doesn't have to think about cultivation if he doesn't survive the six or nine heavenly tribulations. And to improve the soul realm, where can you listen to Qin Yu play the piano quickly.

Originally, he wanted to find someone to fight and have a good time. However, Qin Yu warned him not to cause trouble for the time being.

Xiao Hei, who is fine, can only come to see Qin Yu Refiner. However, Xiao Hei found that watching Qin Yu's refiner was not so boring.

He found that when Qin Yu was refining the instrument, the tinkling sound he made actually resonated with his soul like Qin Yu's piano sound. It's faint, but it's true.

Moreover, as his soul resonated with the sound of Ding Ding Ding, his soul realm actually improved a little bit. This made Xiao Hei very happy. Of course, Xiao Hei still likes to listen to Qin Yu play the piano.

In the following days, Qin Yu spent half of his time refining weapons every day, and then spent the remaining half of his time cultivating, and by the way, he took time to play the piano for Xiao Hei. Sometimes you have to refine a few furnaces of elixir. Therefore, Qin Yu lives a full life every day, and at the same time is very satisfied.
