Bu Yuntian had a conjecture before, a magical conjecture. Is there an invisible spell in the pen "Fun" Pavilion www.biquge.info, the other party can't detect it. When the other party approaches, it will suddenly explode? He gave the spell a new name, Shadowless Thunder.

Such spells can be used both invisibly and invisibly... Ahem, yin others. What's more, there are no traces left that others can't notice.

In response to this conjecture, Bu Yuntian began a formal operation, first clarifying the use of some magic circles.

For example, the Heaven-Covering Array can evade the monk's divine sense, the Invisible Array can be invisible to the naked eye, the Spirit Gathering Array can ensure that the spell always exists, and the Trigger Array, what will happen once it is triggered...... There are a few other formations that need to be added to it.

Boom, boom, boom, the constant sound came from the pavilion in Buyuntian, the sound was very loud and powerful. Several times the outer disciples who passed by saw the attic tremble suddenly, and it almost collapsed. You must know that it was a formation reinforced by the elders, which was enough to resist the attacks of the Cave Heaven Realm.

Three months have passed since this study.

Three months later, a almost complete product appeared in front of Bu Yuntian, but no one could see it.

During this period, Bu Yuntian also adopted the practice of divine consciousness to connect this shadowless thunder with his own divine consciousness. After fusing the Ghost Domain and absorbing some of Shuqi's divine sense, although the strength of Bu Yuntian's divine consciousness is only in the Cave Heaven Realm, it can be said that it is invincible under the immortals in terms of defensive power.

This means that the divine consciousness under the immortal can no longer detect this shadowless thunder, not even the elders of the Holy Heaven Sect!

Bu Yuntian didn't think about whether he could use these spells in battle, but he found that there were too many magic circles used in it. If you use it in real combat, it's definitely very difficult. Bu Yuntian doesn't have time to study more now.

"It's time to experiment. Bu Yuntian's eyes changed, revealing a hint of madness. Looking outside, there were many outer disciples outside the attic at this time.

Researching a new spell requires constant experimentation to make the spell more perfect.

I didn't see a thundercloud appear for three months, the injuries on my body were repaired, and the outer disciples returned to their usual state. Chat from time to time, fly in the sky from time to time, brag from time to time, tease others from time to time.

Cultivating immortals is a long road. After all, not every immortal cultivator has a clear goal and lofty ideals like Bu Yuntian. Some people cultivate immortals, just go with the flow, don't want to waste their talents, just give it a try; most people cultivate immortals in pursuit of immortality, but in terms of perseverance, they are often not as strong as Bu Yuntian.

But when these disciples went out, every time they passed by the Buyuntian attic, they all kept their vigilance, and even went around directly, not passing by this large area.

There were originally a few attics around Bu Yuntian, but since the thundercloud incident, those disciples were fully aware of the extreme insecurity, and even more, they had been attacked by thunderclouds more than six times. They had moved out a month earlier, which meant that Bu Yuntian's surroundings were now empty.

However, Bu Yuntian was not worried at all, even if the other party appeared thousands of miles away, as long as his divine sense could reach it, he would be able to arrange the invisible thunder.

But this time, he also learned the lesson of the last time, and did not compress too many thunder particles to avoid the excessive power generated during the explosion, which caused the disciple to be injured again. However, minor injuries are inevitable. Avoid the last major incident.

As for the powerful invisible thunder, Bu Yuntian decided to find some elders to try. They won't be able to find out anyway, and they won't be able to do any harm to them.

So, one night, all the disciples who had reached the spiritual seed realm could sense Bu Yuntian's divine consciousness and scurry around in the outer gate of the sect. But they didn't pay much attention either. Because during this time, it is often seen, day and night.

The elders didn't pay much attention to it either, just a little strange.

This time, Bu Yuntian's divine sense was not as straightforward as before, but it gave them the feeling of being like a thief, sneaky, cautious, as if he was doing something bad. But they found nothing.

At the end of the night, Bu Yuntian put invisible mines in many important places. He also focused on the last time he studied Thunderclouds, the disciples who teased him.

As for the inner door, Bu Yuntian didn't want to go. After all, he still has an opponent - Bi Qing in it, so it seems that it is not bad to be an experimenter. But on the road through the inner gate, there was a great array that cut off all divine consciousness. Bu Yuntian also sighed faintly in his heart, and then gave up.

Early the next morning, in an attic, a disciple Li slowly went out.

Looking out the window, how good the weather was, thinking of such a beautiful day, his mood couldn't help but be happy, the corners of his mouth were slightly upturned, a happy smile appeared on his face, and his steps couldn't help but be much brisker.

As soon as he walked out of the door, there was a click, and his smile suddenly stopped, and his face was a little strange.

Just now he had determined that there was nothing else on the road, and when he looked down, there was indeed nothing else. But he did hear the clicking sound, and he did feel as if he had stepped on something.

Suddenly, a trace of extreme uneasiness rose in my heart.

Boom, boom. Caught off guard, he didn't react to the whole person, and a wave of spell fluctuations came. The whole body was blown black, and the hair was a little messy. It's just that his face is a little pale, and he hasn't understood what happened for a while.

It took him a long time before he came to his senses and pulled out a mirror. He let out a roar when he looked at himself, and then looked at the people around him with anger on his face. He guessed in his heart that this was definitely someone plotting against him, and it was possible that he was his enemy.

And at this time, it just so happened that in an attic next to him, a disciple of Zhang, who was usually against him, also walked out of the door. This Disciple Zhang also saw Disciple Li, his face first had a trace of stunned, and then he laughed wildly, laughing so much that tears flowed out of his eyes, and he also laughed at him.

This enemy's performance made Disciple Li think that it was absolutely and absolutely the enemy's plot. He must not forgive him for harming him today.

So, he let out an angry challenge. This disciple Zhang naturally did not refuse, but showed a hint of a smile.

It's just that a strange incident happened after that, which made the smile on Disciple Zhang's face disappear.

After a few steps, there was a sound, and he became like a disciple of Li.

When Disciple Li saw this scene, he instantly laughed and laughed, and seemed to be extremely happy.

Disciple Zhang's face became gloomy, he looked around, there was no one here, and there was only one person who could use this spell. Then there is only one truth, that is, his enemy, Disciple Li, is sneaking up on him. dared to sneak attack him, he would never be spared.

The two of them snorted coldly and went directly to the ring area to prepare for a good fight.

Bu Yuntian didn't know about all this, and even if he knew, he didn't care. He pays attention to whether this invisible mine is successful or not.

Elsewhere, many similar events are taking place.
