Immortal cultivation starts with copying.

An hour later, Chen Yunhao walked out of Tianji Pavilion with a painful expression on his face.

The Earthly Evil Falling Star Formation is of medium to upper quality among the fifth-level spiritual formations, and is one of the most important formations in the Tianji Pavilion. Naturally, it is not cheap, costing 20,000 low-grade spiritual crystals.

Of course, the Earthly Evil Falling Star Formation is worth the price, and the spiritual crystals are well spent!

Chen Yunhao had less than 3,000 spirit crystals on him at most, so 20,000 low-grade spirit crystals was a sky-high price for him.

Fortunately, you can exchange spiritual materials, spiritual medicines and other natural treasures in any store, but it will be relatively disadvantageous.

Chen Yunhao was mentally prepared and had prepared the spiritual materials to be exchanged in advance, filling five bulging storage bags.

After leaving Tianji Pavilion, Chen Yunhao went straight to the big rift valley where he had lived before.

Although there is a fifth-level formation, the formation is static and there will be variables in everything.

So he had to make another preparation and invite someone he knew.

The person Chen Yunhao was most familiar with in Lock Dragon City was Zhou Ang.

Zhou Ang's cultivation level is similar to his, and he is not much older than him. Any casual cultivator who can reach the level of Lianxu is not a simple person.

As far as Chen Yunhao knew, Zhou Ang could neither refine pills nor refine weapons, but he had been renting here for years, so it seemed that he had a special way to make money.

"Fellow Daoist Chen, I heard that you have left Dragon Lock City?"

Zhou Ang asked with some surprise when he saw it was Chen Yunhao.

"I went to visit a friend a few days ago. I came back this time specifically to ask for your help. I'm sure you'll benefit from it after this is accomplished..."

"Fellow Daoist Chen, come in and tell me..."

After a stick of incense, Zhou Ang and Chen Yunhao both left.

Chen Yunhao explained the general situation and said that Master Liu from the Five Thunder Sect was his good friend and that he must help with this matter.

As for inviting Zhou Ang to go, it was also a foolproof plan.

If the formation trapped the three Nascent Soul cultivators of the Zheng family, Chen Yunhao could kill all three of them by himself.

If an unexpected situation occurs, Zhou Ang needs to stop one of them.

Zhou Ang didn't need to exert much effort, he just needed to restrain one person. Afterwards, Chen Yunhao promised to give him two thousand-year-old purple wisteria fruits.

If Zhou Ang could kill a Nascent Soul cultivator from the Zheng family, all the spoils would belong to him. Chen Yunhao would not take a penny, but he would also promise a lot of benefits.

If things cannot be done, Zhou Ang can retreat on his own, and Chen Yunhao will not blame him.

This condition was very relaxed, so Zhou Ang agreed after just a moment of thought.

The thousand-year-old wisteria fruit is also a rare treasure and can be used just right. Zhou Ang has no reason to refuse.

For independent cultivators like them, who have no special skills, the only way they make money is by doing things for others. Of course, they can also take risks to explore some caves, but it is not stable.

Both of them are cultivators of the Void Refining Realm, so their escape speed is naturally extremely fast.

Zhou Ang had obviously practiced a special escape technique, and his speed was not slower than Chen Yunhao's Flowing Light Technique. It can be seen that every casual cultivator of the Void Refining Technique is not simple.

The two of them did not stop along the way, deliberately bypassing the Zheng family's territory, and quietly arrived at Wulei Mountain a few days later.

For the next few days, the gate of Wu Lei Gate remained closed.

Chen Yunhao returned to Wulei Mountain and spent three days refining and mastering the Earthly Evil Falling Star Formation.

Then he spent another day quietly setting up the Earthly Evil Falling Star Formation at the foot of Wulei Mountain.

Although the gates of the Five Thunder Sect have been closed these days, a lot of news has been circulating in the market, saying that Master Liu has gone astray while practicing.

Regardless of whether this news is true or not, there is no way to verify it, because there are only a few people in the Five Thunder Sect, and the mountain gate is closed, so no news has leaked out.

At first, people didn't take it seriously. Although the Zheng family had been secretly watching the Wu Lei Sect, they thought it was just a rumor.

However, after the Wu Lei Gate closed the mountain gate, it has not been opened since then, and this situation lasted for three months.

This caused the Zheng family to become restless. The Wu Lei Sect was already in a dilapidated state. If the gate was closed for such a long time, the disciples would not eat or drink, and would cause trouble after a while.

Another month passed like this, and the Zheng family still hadn't heard any useful information, but they became more and more convinced that a huge change must have taken place in the Wu Lei Sect.

The opportunity was fleeting, and Zheng Tianjun, the ancestor of the Zheng family, could no longer hold back. He mobilized more than 2,000 disciples in the family who had reached the foundation building stage and above, and rushed towards the Five Thunder Gate in a mighty force.

Chen Yunhao has been keeping an eye on the Zheng family these days. Since he is an outsider, it is not easy for him to attract the attention of the Zheng family.

This was the method he and Master Liu had discussed to lure the snake out. As long as the Zheng family reached the Five Thunder Gate and automatically entered the formation set up by Zhen Yunhao, the plan would be accomplished.

Sure enough, the Zheng family was fooled and lost their patience.

The Zheng family was only about three or four thousand miles away from the Five Thunder Gate, and they had dispatched twenty or thirty giant flying boats, which clearly showed that they had been prepared in advance.

It's a distance of thousands of miles, and even if the flying boat is at its slowest, it will only take more than an hour to arrive.

When thousands of people from the Zheng family surrounded the Wu Lei Gate, the entire gate was still quiet, as if the entire gate was deserted.

The ancestor of the Zheng family stood in the air with his hands behind his back, and on his left and right were his two sons who were in the middle stage of the Void Refining stage.

"Master Liu, my Zheng family does not wish to engage in a bloodbath. If you can take all of our disciples and leave Wu Lei Mountain, I will spare you. Otherwise, I will annihilate the entire Wu Lei Sect today..."

Although Zheng Tianjun, the ancestor of the Zheng family, has white hair and beard, his domineering aura has not diminished in the slightest.

Perhaps because he has been in a high position for a long time, his chin is slightly raised, and he looks down on others.

After all, the Wu Lei Sect is an old sect that has existed for a long time, and the restrictions at the mountain gate are not easy to break, so it is better to attack the enemy's heart at the beginning.

Ha ha……

A cold laugh was heard, and a figure appeared not far from the Zheng family's ancestor.

"Zheng Tianjun, you are going too far! If it weren't for the generosity of our Five Thunder Sect ancestors who allowed your Zheng family to develop here, you wouldn't be where you are today...!"

The person who just appeared was Master Liu. His face was pale, his breath was weak, and he looked like he had gone astray.

Zheng Tianjun winked at his two sons behind him, and the three of them flashed across a distance of a hundred feet and surrounded Master Liu.

"That's wrong. Things change over time. This place belongs to my Zheng family..."

The second son of the Zheng family chuckled.

"Master Liu, now that you're out, don't go back. Get started...!"

In fact, Zheng Tianjun had no intention of letting the Five Thunder Sect go. In the world of immortal cultivation, if you don't get rid of the roots, there will be endless troubles.

Before the three of them could take action, the scene before their eyes suddenly changed, as if they had moved to a different time and space.

Of course, it was Chen Yunhao who hid in the dark and quietly activated the Earthly Evil Falling Star Formation.

This Earthly Evil Falling Star Formation was created according to the order of the seventy-two Earthly Evil Stars. It has thirty-six levels of defense and thirty-six levels of attack and killing.
