At this moment, Yan Jie was mentally impressed by the old Taoist priest and Yu Zhenzi. He no longer paid attention to the two thunders whistling above his head. He now put his body and mind on the operation of the "Five Thunder Method" and only one thought in his mind: he must put the thunder energy raging in the meridians into the Dantian!

However, as the old Taoist priest said, Yan Jie's cultivation is really too low.

Although this thunder has been weakened by the formation, Yan Jie's all attempt to absorb it is definitely not a task that can be completed in a short period of time. However, Lei Jie will not give him so much time at all.

When the first thunder disappeared, two electric dragons rushed out of the robbery cloud at the same time and rushed down towards Yan Jie below.

The old Taoist and Yu Zhenzi both held their breath. They really couldn't think of any other way Yan Jie could stop this second wave of tribulation thunder.

However, a miracle happened.

The two electric dragons were entangled with each other and descended at an extremely fast speed, but suddenly stopped when they were only one meter away from Yan Jie's head. This feeling was very strange. The thunder roared at the moment, but suddenly stopped the next moment, as if someone pressed a strange time button, freezing the picture at this moment.

The next moment - four beams of light were shot out from four directions in the southeast, west and northeast of the formation, and the powerful formation barrier was formed again. The two electric dragons were still swaying in their teeth and claws at the last moment, but when they touched the four-color barrier, they entered the mud cow and entered the sea, disappearing without a trace.

Yu Zhenzi was so shocked that her chin was about to fall off, her face was filled with incredible thoughts, and she exclaimed: "How is this possible! The array source has been exhausted, so how can this barrier still appear? Could this formation be able to operate without the array source? This makes no sense!"

At this moment, Yu Zhenzi even felt that his understanding of the whole world was collapsed... He had to turn his eyes to the old Taoist beside him, hoping that this "old god" could save him.

However, the old Taoist was shocked at this time than him. If he hadn't been concerned about his image, he would have jumped up in shock!

Seeing Yu Zhenzi looking at him with a puzzled look, the old Taoist priest suddenly remembered the messy knowledge that Yan Jie taught him more than ten days ago. At that time, he was confused, but at this moment he seemed to understand: the formation must not have a source of formation. There is only one reason why the magic array in front of him can still operate: Yan Jie used a new source of formation!

After thinking about this section, the old Taoist priest immediately recalled what Yan Jie said before he was in seclusion and murmured: "Can this kid say I am true? Can the thunder of robbery really become a source of formation?"

Yu Zhenzi was confused when she listened on the side. Isn’t this a fantasy of using the catastrophe as a source of formation? Who doesn’t know that once the catastrophe is formed, she can only rely on the cultivator’s own strength to resist and cannot escape, let alone use the catastrophe as a source of formation.

However, Yan Jie created a miracle under his nose. Apart from this explanation, Yu Zhenzi could not imagine any other way to do this. He knew that there was a huge secret in front of him, but he just couldn't understand it. Yu Zhenzi felt like a cat was scratching her, and she wanted to open the old Taoist's mouth and ask clearly.

However, after the old Taoist priest said this, he kept silent and let Yu Zhenzi say it in a mess. He just kept silent and completely treated Yu Zhenzi as air.

Yu Zhenzi knew in her heart that this old Taoist was waiting for him to offer a offer!

This old mao has always never seen a rabbit or a hawk, and now it is no exception. He doesn’t forget to blackmail his disciples when he is passing the tribulation by his side. It’s really a shame!

Yu Zhenzi had a bead of eyes and suddenly glanced at the two yakshas in the distance. He immediately had an idea. He smiled and said to the old Taoist priest: "Please look at the immortal. Those two yakshas are the underworld species, and they are all treasures. The immortal is proficient in the way of talismans, and this yaksha is more useful to you. It just so happens that the talent of the lower class can restrain the ghosts of the yellow spring. If the immortal is unavailable, he is willing to work hard to capture them and give them to the immortal... I have no other requirements, I just hope that the immortal can solve my doubts."

"Hey, what do you mean? Isn't I the kind of person who is greedy for small profits?" The old Taoist priest defended his words with a few words, suddenly changed his tone and whispered: "When you catch the yaksha for a while, don't hurt its wings and sharp corners, that's an excellent talisman-making material!"

Yu Zhenzi agreed, and she had already cursed this shameless veteran in her heart.

When the old Taoist priest saw that Yu Zhenzi was so well-educated, he no longer kept him in his arms and explained: "The veins of Qingyang Mountain are disordered and are not an ideal place to set up a formation. The reason why I chose to overcome the tribulation here was that I was attracted by the geomagnetic power here - this entire Qingyang Mountain is actually a magnetic mountain!"

"The power of geomagnetic?" Yu Zhenzi is very familiar with the power of geomagnetic. The key to the "floating" magical power he wants to comprehend is to sense the power of geomagnetic. However, what does this power of geomagnetic has to do with tribulation? Yu Zhenzi can't figure it out.

The old Taoist priest could not learn from his disciples. Whenever he was involved in the problem of formation, he would ask his disciples for advice. Now someone is willing to listen to his teachings and immediately explained: "The characteristics of this geomagnetic power are very strange. It is a matter of life for many demon races, but human monks basically cannot sense its existence. However, there is a characteristic of this geomagnetic power that my disciple has studied thoroughly: that is, this geomagnetic power can induce thunder, and the relationship between the two is perfectly in line with a set of equations, which is the core principle of all this in front of us."

"Formula? What is that?" The old Taoist priest's explanation was even more profound than the "Turt Breath True Sutra". Yu Zhenzi completely didn't understand it. Yu Zhenzi belonged to the demon clan and was very familiar with the power of geomagnetics, but he had never heard of any induction between the power of geomagnetics and lightning. One of these two is in the sky and the other is on the ground, and it has nothing to do with it!

In fact, the old Taoist priest himself doesn't understand the meaning of Maxwell's equation, but this does not affect his use to show off. Anyway, Yu Zhenzi doesn't even know what the equation is, so he naturally does what he wants to do.

The old Taoist coughed and said, "This equation is a profound knowledge of the human race. Now you can't understand it. As long as you know that magnetic force can induce lightning, that's enough. The lightning array in front of you has been transformed to stimulate the geomagnetic force of the entire mountain range and form a ring-shaped magnetic field. When the electric dragon falls, the geomagnetic and lightning induce each other, and the lightning can be bound to the magnetic field. Although the thunder tribulation is powerful, it cannot be

It can be bound by the geomagnetic for a long time, but it is enough to buy a lot of time for those who have passed the tribulation. In fact, the power of the geomagnetic is very powerful, and the ability to bind the tribulation thunder is beyond imagination. Not only that, the superconducting material in this formation also has the effect of diversion of lightning. On the one hand, it extends the time when the thunder tribulation arrives; on the other hand, it transforms a thunder into tens of thousands of branches through diversion, and enters the body in sequence in sequence, which greatly reduces the difficulty of thunder!"

The old Taoist priest's explanation made Yu Zhenzi so shocked that he couldn't speak. Although cultivators showed their magical powers through tribulation, Yu Zhenzi was sure that no one had tried Yan Jie's idea of ​​tribulation.

However, Yu Zhenzi is not that easy to fool. He soon thought of a key question: "Immortal Crow, as far as I know, the formation must be supported by the formation source, but the formation source of this formation is only ten top-grade spirit stones, and it was exhausted when the first thunder was thunder. But now the formation is still running, which is completely unexplainable!"

"I want to know this question," the old Taoist priest spread his hands helplessly and said, "This kid's formation skills are far superior to me. I have no idea about his changes to the formation source..."

I didn't understand what you're showing off here!

Yu Zhenzi was so depressed, but she couldn't say anything about her pain. She could only look at Yan Jie who was passing through the tribulation in the distance with a complicated look, and her heart was mixed.
Chapter completed!
