The best wisdom sword hung in the air, and Jin Yu Tianhuo spit it out, enveloping it in it, and then began to slowly refine it.

An hour passed, and Jin Yu began to pinch the trick with both hands, and kept punching hand seals into the Hui sword. His palms seemed to be flying all over the sky, and he saw the power of countless laws, like a hundred birds and phoenixes, swarming and merging into the wisdom sword.

Ten days passed.

Jin Yu's handprints never stopped. And the light of the sword is getting stronger and stronger. It's like an elf about to transform. It's clearly the last minute.

Jin Yu's expression became more and more solemn.

But at this moment, in the best wisdom sword, there was a sound of 'click', Jin Yu's face suddenly changed, and on the almost transparent wisdom sword, it seemed that it could not withstand the power of these laws, and small cracks actually appeared, and immediately, these cracks expanded rapidly, and before Jin Yu could come up with a remedy, the wisdom sword 'Peng' exploded on the ground, and instantly collapsed, turning into countless fine dust, scattered in the void.

"It's not that easy. ”

Jin Yu stared blankly at the collapsed Hui Sword, frowning slightly.

The reason for the failure is not that there is a problem with the refining method. He operated in full accordance with the refining method of the Instrument God, and he believed that the Instrument God had no reservations. But even if this method is a machine god, the success rate is extremely low.

But at this moment, a voice suddenly came into his sea of knowledge:

"Jin Yu, if you continue refining like this, you won't succeed once in ten times. ”

Jin Yu was stunned, this was actually the voice of the dream god. Although the Extinction Fork was placed in the ring by him, the Oneiroi was his instrumental spirit, and it did not affect the Oneiroi to poke out his divine sense at all. She knows everything Jin Yu does.

At the same time, Jin Yu suddenly remembered that the Oneiroi as the instrument spirit of the World Destroying Fork must have seen the master refining weapon. He was immediately overjoyed, and hurriedly asked, "Dream, is there a problem with the method given to me by the instrument god?"

Oneiroi said leisurely: "There is no problem with the refining method he gave you. It's just that he doesn't know that there is another way to increase the chance of refining success to eighty percent. ”

Jin Yu's eyes immediately widened, he was simply ecstatic, and hurriedly said, "Dream, you must know this method, right?"

"Hehe, of course. Oneiroi's voice was full of pride, as if he had paused deliberately, satisfying Jin Yu's appetite, and then said easily: "In fact, the way to increase the probability of success is very simple, you only need to break a Yuan Magnetic Branch, as long as the length of your arm is a piece of it, and refine him into the best artifact, then the possibility of advancing to the spirit treasure can be increased to eighty." ”

Jin Yu's eyes widened, as if he had been enlightened, and suddenly woke up.

The Yuan Magnetic Divine Tree is not a tree at all, but an innate spirit treasure that can grow on its own! Adding a little innate spirit treasure to the best artifact can naturally increase the chance of advancement!

He walked out of the enchantment without hesitation, and when he arrived in front of the Yuan Magnetic Divine Tree, he snapped off an arm-length branch with a wave of his hand. Such a small section is completely worthless for tens of thousands of feet of Yuan Magnetic Divine Tree. However, after Jin Yu broke off the branches, he clearly felt that the Yuan Magnetic God Tree seemed to twitch slightly, as if it was in pain.

Jin Yu couldn't help touching his nose, secretly saying that he was really stingy. He took the branch back into the barrier and immediately began refining it.

After all, the Yuan Magnetic Divine Tree is an innate spiritual treasure, which is completely different from the ordinary ninth-level divine material, it contains very few impurities, and the vitality is extremely vigorous, and it is not comparable to the ninth-level divine material at all.

For the Innate Spirit Treasure, ordinary flames can't be tempered at all, not even ordinary heavenly fires, they must be the top-level divine flames.

Fortunately, Jin Yu has the fire of Nine Nirvana, and refining is not a problem at all.

As soon as his mind moved, the powerful Yuan Magnetic God branch was wrapped in the even stronger Nine Nirvana Fire. After an hour, the impurities contained in the branch are slowly removed.

The refining process of the Yuanci branch was much smoother than Jin Yu imagined.

But before he could rejoice, an accident happened.

At the last moment of the branch refining, as the impurities were thoroughly quenched, the vigorous life breath contained in the branch was instantly dissipated. Immediately, the whole branch, with a "snap", broke into two. The level of the Yuan Magnetic Tree Branch actually fell from the Innate Spirit Treasure to the ninth-level Divine Material!

"What's going on?" Jin Yu's eyes widened and he asked Oneiroi in amazement.

"I don't understand that either. I only know that adding the Yuan Magnetic Tree Branch can increase the chances of advancing to the Spirit Treasure. But I don't know exactly how to join. Oneiroi said calmly.

After all, she is just a tool spirit, although she has seen the master refining weapon, but the master has not taught her the refining technique.

Jin Yu was immediately silent, frowning and thinking hard.

He didn't know what caused the breath of life to dissipate at a critical moment. Because the method of refining the material is the same as before, and nothing has changed. It stands to reason that there should be no accidents.

In order to verify his judgment, he took out a ninth-level divine material, an eighth-level divine material, and a seventh-level divine material, and used the original method to refine the material, and the results proved that there was no problem. All materials are tempered to the utmost purity. He even directly refined a Thunderbolt Hybrid Spear without encountering any problems.

"It seems that the problem is on the branch of the Yuanci tree. Jin Yu came up with an answer.

Obviously, the Yuan Magnetic Tree Branch is different from the ninth-level divine material, and when it is refined, some changes must be made.

Without hesitation, Jin Yu broke a branch of the Yuan Magnetic Tree again, allowing the Yuan Magnetic Divine Tree to twitch exaggeratedly, he only pretended not to see it, returned to the enchantment, and began to refine it twice.

This time he didn't rush any further, but just cut off a large piece of his fingernail, hung it in the air and began to burn it with flames. However, his divine sense has been extended to the limit, and all the changes in this small branch have been observed in great detail.

For a period of time, he burned the branches without stopping, carefully observing the reaction and change of the material.

It wasn't until the entire branch was scrapped again that Jin Yu finally confirmed one thing, and there was a shock in his eyes at the same time.

It turned out that every time this branch discharged a trace of impurities, that breath of life would dissipate a little, and when he discharged all the impurities, the vitality of the branch seemed to have nothing to rely on, as if it had been drained of its vitality, and it instantly fell to the ninth-level divine material.

This means that impurities are an important part of the innate spirit treasure, and it is precisely because of the perfect fusion of impurities with their main components that the breath of life is born.

In addition, he also found that the ingredients of the Yuan Magnetic Tree Branch were very ordinary, and even like many ninth-level divine materials, in terms of efficacy alone, these ingredients were not even as good as some of the best divine materials.

Impurities turned out to be an indispensable part of the metamagnetic branches. Therefore, the more impurities that the golden rain removes, the greater the damage to it.

It can be inferred from this that the Yuan Magnetic Divine Tree is like this, so is it the case with other innate spirit treasures?
