Chapter 2712

Li Yifan landed on the square and restarted the battle here.

Although the boundary of the great array was destroyed, it can still be used. The main reason is that he forged immortal utensils, which will surely lead to the vision of heaven and earth, so he chose to come here.

With the cover of the border, no one will notice here.

Within a few minutes, the formation was restored and then restarted, forming a huge barrier to cover the sky.

From the outside, it's just like what we saw at the beginning.

"Next..."

He took out ten famous swords and suspended them in front of him.

"What are you going to do?" The spirits seemed to feel his purpose.

"I'm going to upgrade you." Li Yifan replied.

"Upgrade?"

"You want to forge us again?"

The spirits were surprised, "but we've all set the pattern. It's hard to do that, isn't it?"

"There's nothing you can't do."

Li Yifan's expression was calm and he thought a little. He took out the sky sword and the green white snake sword.

"The number of ten swords is not suitable to form a sword array. It's better to add two more and imitate the twelve immortal sword formation. "

From the point of view of level, the sky sword and the green white snake sword are both semi artifact, which are one level lower than the top ten famous swords.

As for not taking the seven star sword, Li Yifan has his own considerations.

The Seven Star heavenly punishment sword is different from these twelve swords in forging ideas from the beginning. The twelve swords are all based on the concept of overall forging, that is, they are not built with modular splicing forging ideas like the Seven Star heavenly punishment sword.

Therefore, the strength of the twelve swords is very single, unlike the Seven Star heavenly punishment sword, which has both attack and defense, and can use many kinds of strength.

For a sword array, as each individual of the sword array, the strength simplification is the best, and it must be pure enough, otherwise it will interfere with the strength of the whole sword array.

So the Seven Star heavenly punishment sword can't be a member of the sword array.

In addition, from the perspective of growth, the Seven Star heavenly punishment sword is actually more growth than the twelve swords. Because of the unique forging idea, the Seven Star heavenly punishment sword is equivalent to the splicing of components, so it can be repeatedly forged, which means that it can be infinitely improved. As long as there are appropriate materials, it is most likely to become an immortal.

At present, after years of running in, the strength of the Seven Star heavenly punishment sword has reached the same level, reaching the level of demon saint, which is equivalent to the human warrior in the robbery period.

Originally, Li Yifan also planned to upgrade the Seven Star heavenly punishment sword. However, he had enough suitable materials, so he upgraded the top ten swords first.

"Let's go!"

Li Yifan yawned and took out a lot of materials from the storage ring.

Most of these materials were collected by him when he was refining utensils at luotiandajiao. Among them, there are some top-level materials. In addition, his previous works, such as Tianhan meteorite and Sixiang Wuji flower, are absolutely enough to upgrade all twelve swords to the level of semi immortal utensils.

"Poof!"

As before, he released more than a dozen separations for division of labor and cooperation, which can speed up efficiency to a greater extent.

He asked some of them to refine materials with chaos fire and sky fire, and the others to complete the next process, so that the materials and swords could be integrated, and finally forged and upgraded.

This efficiency is much higher than before, and with the improvement of his cultivation, chaos fire has completely recovered its strength, and the time needed to refine materials is greatly shortened.

In less than one day, he completed the fusion of the twelve swords and forged the twelve swords with new materials.

"The last step is the baptism of thunder."

Li Yifan looked up at the dark clouds in the sky. He was very familiar with this scene, so without saying a word, he let twelve swords fly to the sky.

"Boom!"

Dark clouds rolled and thunder surged.

Li Yifan gazed at the thunder clouds in the sky and suddenly said, "eh? This time, the color of Tianlei seems to be different from before. "

He remembers that when the artifact was born, the sky thunder was nine Xuan sky thunder, and the colors were colorful, which was very easy to identify.

But this time, he found that the colorful thunder quickly turned into a pure black, and from the power, let him feel a very dangerous breath.

"Is this the thunder that the immortal tools need to accept when they are born? The color is really special. "

He guessed that when the lowest level of immortal ware was born, it should be this kind of black thunder.

I just don't know what to call it.

He can be sure that the sky thunder can't be compared with chaotic sky thunder. After all, chaotic sky thunder is the highest form of sky thunder, but the black sky thunder can't be underestimated.

"Boom!"

Thinking, the black sky thunder slashed on twelve swords.

The black arc of thunder is like a spider web, with twelve swords as the center, and even spread the surrounding mountains and rivers.Li Yifan was surprised. "The power of this Tianlei is far stronger than that of jiuxuan Tianlei, and it is totally different from jiuxuan Tianlei. Jiuxuan Tianlei is not destructive to artifact, but this black Tianlei is full of destructive. "

He saw that the mountains affected by the thunder were all cut into scorched earth.

At the same time, he released the power of his soul to devour the superfluous power of thunder.

"Zizi!"

Thunder is rampant and the aftershocks are violent.

Li Yifan soon felt the horror of the black sky thunder. When he devoured the power of the black sky thunder, he actually felt a kind of oppressive power.

"Hum, I can even carry the chaotic thunder, and I'm afraid of you?"

Of course, he was not afraid at all. These thunder are really terrible and strange, but they are much worse than chaotic thunder.

The tug of war lasted until four days later.

Li Yifan was relieved that day after the thunder dispersed. At the same time, he was slightly surprised. "This time, the time of Tianlei baptism is longer than ever before. Should it be said that it is worthy of the celestial thunder baptism that can only be accepted by immortal tools? "

In the past, when he forged a weapon, the time of Tianlei baptism was usually one day, at most two days. This time, it lasted more than four days.

When Li Yifan reached for his hand, twelve swords flew to him one after another. He observed for a while, nodded secretly, "yes, they have become semi immortal weapons. If they form a sword array, they should be able to play the power of the immortal weapons."

If it's immortal, it's enough for yulinglong to drink a pot.

"I didn't expect that I could become a fairy in my lifetime!" Longquan sword spirit is very excited.

"Although it's only a semi immortal, it's also amazing. At least it's a immortal," Chengying jianqiling was very satisfied.

"In the end, there is no mistake in the second forging," Chi Xiao sword said.

Li Yifan light way: "at least also used a lot of top material melting effect."
