It took more than ten days, and Bu Yuntian finished reading all the books about the formation in the demon cultivation. Pen "Fun" Pavilion www.biquge.info but even if you step into the realm of epiphany, to understand the formation. Bu Yuntian's understanding now is only a superficial layer of the formation. At least I know what is the formation.

The formation is to use the aura to make the aura of heaven and earth arrange according to a law, so as to exert different effects. It's a little different from spell casting, but it's also a little the same.

"So can you use those thunder particles in the spell casting, and arrange the magic array, so as to realize the formation spell, that kind of power should be huge. Bu Yuntian's eyes showed a hint of excitement, and then he began to act.

Thunderclouds appeared in front of them, and they were still the one hundred and twenty-eighth generation thunderclouds. This time, Bu Yuntian is ready to try it on it.

Thundercloud, when acting, needs to continuously inhale the aura from afar, so can it be allowed to absorb the aura on its own, and no longer need to enter the aura. In that case, it can even last forever.

Before, Bu Yuntian had also thought about this problem, but there was no way to do it. Now he saw a glimmer of hope, there was a spirit gathering array in the formation, which could absorb the surrounding spiritual energy. If there is this formation in the thundercloud, it is equivalent to a person inputting aura. If it is even possible, enter the relevant things and let the thundercloud move automatically, without even human operation.

Thinking of this, Bu Yuntian's eyes showed great interest and began to keep trying.

The thunderclouds in front of Bang kept exploding, and Bu Yuntian's face continued to turn pale, obviously the aura consumption was a bit large. In the end, he directly held the Emperor Spirit Stone in his hand, and tried while recovering his aura.

Fifteen days passed, and Bu Yuntian finally completed the first step without eating or drinking, and the spirit gathering array was engraved in the thundercloud, but he didn't wait for him to be happy for a few minutes. With a bang, the entire thundercloud suddenly exploded.

"If you build a magic circle and inhale aura, it will destroy the structure of the original spell, and it will explode. It must be isolated, leaving a small passage to transport the aura. Bu Yuntian frowned, thought for a moment, then knew what the problem was, thought of a solution, and began to act again.

Half a month later, the thunderclouds finally stabilized. But all this has not yet met the requirements of Bu Yuntian.

His idea was to allow the thunderclouds to reach a certain place on their own, rather than relying on people. The current thunderclouds can only be regarded as saving aura, but the control of the direction has to be human. For this item, Bu Yuntian studied for a month before completing part of it, and the rest needed to be tested experimentally.

The space in the attic is too small for the thunderclouds to perform. Bu Yuntian prepared to let the thunderclouds go to the outside of the attic. The confinement given by the sect master only told him not to go out, but it didn't say that his spells couldn't go out.

Then in the following month, almost all the outer disciples saw a strange thundercloud.

From time to time, this thundercloud flew around the sky, sometimes there, sometimes somewhere else. If that's all there is to it, these outer disciples would only feel strange at best. However, this thundercloud not only flies in the air, but also explodes.

When a senior brother of the fruiting realm passed by in the air, he saw this thundercloud approaching, and he was very curious, and he didn't care about it in his heart. But all of a sudden, the thundercloud exploded, and the power of the explosion was equivalent to a blow from the Result Realm. As a result, that senior brother was miserable, and he had been cultivating for a long time.

There are also many disciples who have also been poisoned.

Regarding their experience, Bu Yuntian mourned silently in his heart. But there is no way around it, he is already working on the control, the stability of the automatic movement.

"Oh my God, it's that thundercloud, get out of the way. ”

A month later, all the disciples saw this thundercloud avoiding it one after another, and their faces showed a hint of fear. Countless lessons of blood and tears taught them not to approach this thundercloud easily. There are countless brothers and sisters who have verified this truth.

In the end, they also found out where the thundercloud came from, which was Bu Yuntian's residence, and their faces were a little relieved, although they were angry, but they were a little helpless. If Bu Yuntian had made it, they wouldn't have thought anything strange.

Now Bu Yuntian's prestige in the outer gate has reached a very high level, almost to a point where no one can provoke him.

In broad daylight, in front of countless disciples, he killed three outer disciples in a row, and one of them was a Shuqi who was preparing to participate in the battle of luck. And the punishment is only a year of confinement, which is not a punishment of punishment at all.

Such a fierce character, no matter what unthinkable things he does, it seems to them that it is very normal. What's more, there are countless precedents for stepping into the clouds.

Towards the end of a month, Bu Yuntian had successfully achieved the autonomous flight of thunderclouds, but he also discovered an extremely fatal problem. Once the monk casts a spell attack on the thundercloud, the thundercloud will automatically explode. This is the result of experiments by many disciples.

"That's not going to work. Bu Yuntian frowned, and began to improve again.

If this is the effect, you sit on the thundercloud and close your eyes to rest, and a spell suddenly strikes, and then the whole thundercloud explodes, and before you can deal with others, you are estimated to be seriously injured.

So, a month later, the outer disciples were surprised to find that this thundercloud was not flying around now, but would follow it and pounce directly on you. No matter what you dodge, it will stick to you, and it's not usually fast. However, there were still countless disciples who cast spells, and then countless disciples fell into a state of serious injury.

After learning many lessons, the outer disciples saw the thunderclouds from a distance, and they prepared to make a detour or not go out of the attic.

For a while, there were many fewer outer disciples walking outside. Either to go on a mission, or to stay in the attic and not dare to go out.

He didn't care about these Bu Yuntian at all, half a month has passed, and his current final form thundercloud, the 1180th generation thundercloud, has finally come out, and his appearance has changed a little, and it looks more pleasing to the eye. At the same time, it also has the speed of the explosion acceleration of the one hundred and twenty-eighth generation, no, it should be said that the current version of the thundercloud is faster.

So, from time to time, a thundercloud could be seen, flying around in the sky, without flying randomly and without exploding. But as soon as the outer disciples saw it, they immediately avoided it, and they saw the miserable appearance of those senior brothers and junior brothers before. Even some of them have injured victims multiple times.

After flying for about half a month, Bu Yuntian finally nodded with satisfaction. Such a 1,180th generation thundercloud is already the most perfect form he can achieve now. If you have any other ideas, keep researching. Not now, though. Now he's going to work on other spells.

On the way to Naqingshan Town, Bu Yuntian had a trace of conjecture, but he had no clue. Now, knowing this formation, his conjecture may really come true.

If it does, it can definitely hurt people and be invisible! With this spell, Bu Yuntian is more confident that he will win the first place in the battle for luck, and he will be able to take the lead in the future duel, and he will be safer in the future.
