Unparalleled War Emperor

Yun Yi had come into contact with these formations before. They looked very similar to the formations he usually came into contact with, but they were also very different. In other words, they evolved from real formations.

Although the effects were not much different, they were two completely different things.

The most important thing was that there were many formations here that he had never come into contact with before. In other words, most of them were immortal formations. With Yun Yi's current realm, it would take a lot of time and energy to fully understand them.

Fortunately, he had the help of the Buddha's Eye and the special energy of this place, which made him feel twice the result with half the effort. In addition, with the reference of the Yuan Zhen Tian Shu, his progress was very rapid.

Slowly, Yun Yi entered a peculiar state, and the speed of comprehending the formations was significantly improved.

It was unknown how long it took for Yun Yi to exit from this state. At this time, he had completely comprehended all the formations here.

Moreover, under the mutual confirmation of the two, Yun Yi's attainments in the Yuan Zhen Tian Shu were also greatly improved.

But Yun Yi knew that comprehending these formations was just the beginning. If he wanted to engrave ninety-nine and eighty-one formations on an immortal weapon, he had to combine these formations.

Let these formations interact and influence each other to form an organic whole.

Otherwise, these formations will fight each other and form a scattered situation. No immortal weapon may not be able to carry such a formation.

Even if there is, the power of these formations will restrain each other, which will greatly reduce the power of this immortal weapon.

But this is easier said than done. It's like selecting soldiers. Each soldier has his own advantages and disadvantages. As a general, he must let these soldiers complement each other and make up for their shortcomings in order to form combat effectiveness.

This is a big problem in itself.

"By the way, why did I forget the combination formation."

Just when Yun Yi was thinking hard and couldn't find a way, he suddenly remembered the combination formation he had used in the lower world, such as the Nine Spirits Battle Formation, which is one of the combination formations.

Yun Yi used the Nine Spirits Battle Formation at the beginning, just to gather the power of Bai Sheng and the other nine-headed snowmen together, but in fact, that was not the limit of the Nine Spirits Battle Formation.

Its real function is to gather the power of the nine battle formations together. Each spirit corresponds to a spirit. This is the real Nine Spirit Battle Formation, the real Nine Spirits.

In other words, the real Nine Spirit Battle Formation requires ninety-nine eighty-one people to work together to exert its true power.

In the Yuanzhen Heavenly Book, there are many similar combination formations, but in comparison, the Nine Spirit Battle Formation is the simplest and most suitable for the current situation.

In other words, as long as you use the Nine Spirit Battle Formation as a basis and transform the people who set up the formation into the formation, this problem will be solved.

But this matter is simple to say, but it is still as difficult as ascending to heaven to do it. Yun Yi used a powerful immortal soul to simulate several times in the sea of ​​​​gods, but it ended in failure.

After all, the more formations involved, the more difficult it is to control.

"It would be great if the formation could be repeated."

Yun Yi sighed, there are too many types of formations, and it is inevitable that there will be some problems of one kind or another. He just solved this problem, and another one popped up.

He said he was simulating the formation, but in fact he was constantly patching it up, which was like suppressing one problem but causing another to pop up, in order to make the entire formation unified.

But in the end, he still failed.

It was not because his level was not good enough, nor was his idea not good enough, but because there were contradictions between these formations. In other words, they were irreconcilable.

If they were put together by force, Yun Yi could still suppress them when there were few of them, but with the addition of other formations, the formation would become fragile and useless even if it did not fail.

Therefore, Yun Yi sighed like that, because the biggest problem he faced now was that there were too many types of formations.

If the formations could be reused, then he only needed to pick out a few formations that had no or less contradictions with each other as the basis of the entire formation, and all the problems would no longer exist.

"Wait!" Suddenly, a light flashed in Yun Yi's eyes, and he thought to himself: "The test of this level is just to use the existing materials to refine a fairy weapon that can accommodate ninety-nine eighty-one formations. As for the formations, it only says that there is no limit to the types. Doesn't the unlimited types here mean that these formations can be repeated?" The four words "unlimited types" have explained a lot of problems. After all, using two identical formations also falls into the category of unlimited types. If this is the case, the problem that troubled Yun Yi will be solved. Thinking of this, Yun Yi immediately became energetic, and found nine formations that had no or less contradictions between them from these formations, and used them as the basis to form the Nine Spirit Battle Formation. Sure enough, this time the Nine Spirit Battle Formation did not collapse like before, but was extremely solid. Yun Yi believed that if such a formation was engraved on the fairy weapon, it would definitely allow the fairy weapon to exert a terrifying power far beyond its grade. "Now everything is ready, except for the magic weapon."

Yun Yi's eyes lit up. At the beginning, he faced many problems, but now they are solved one by one. He only needs the last step to pass the assessment.

He was naturally happy.

However, it is not an easy task to refine a perfect immortal weapon. Fortunately, he has the Jiuji Sword, and its sword shape itself is close to perfection.

Therefore, Yun Yi could completely rely on the form of the Jiuji Sword and then further refine it until it reached perfection, which would be faster than starting from scratch.

Afterwards, Yun Yi sacrificed the Jiuji Sword, and based on its appearance, he refined an earth-level immortal weapon embryo, and then used the storm hammer method to start tempering it.

But after tempering it several times, Yun Yi discovered that the sixth turn of the Storm Hammer Technique was not only able to temper the immortal weapon more thoroughly, but could also fine-tune the shape of the immortal weapon to make it more perfect.

"It seems that the Storm Hammer Technique is more magical than I imagined!"

Yun Yi couldn't help but sigh. In this way, he didn't even need to think about how to modify the shape of the immortal weapon. As long as he tempered it step by step, its shape would be rounded on its own.

In the end, Yun Yi didn't know how many times he had tempered it, and the shape of the sword embryo had shown a very perfect shape. From a distance, it looked like a perfect work of art, which made people unable to put it down.

It's a pity that Yun Yi has only mastered the sixth turn of the Storm Hammer Technique. If he can fully master the next three turns, he can make the shape of the sword embryo even more perfect.

However, he also knew that this could not be achieved in a short time, so he gave up the idea.
