What he wants to set up is not a large formation to kill the enemy. This kind of formation is almost easy to capture.

Then Li Yan made a magic spell with both hands, and a circle of invisible ripples rose vaguely on the ground around the basin. After seeing the ripples rising, Li Yan's body turned into a wisp of smoke again and started to swim quickly in the basin.

Wherever he passed, there was an extremely faint and invisible afterimage behind him. The rest was no different. It was just that when no one saw it, the hands in Li Yan's sleeves were moving around, and there were invisible auras.

Scattered out.

Those invisible energies either rise or fall. Those that fall sink to the ground, while those that rise are restricted to the sky above the basin under the control of the formation. They are formless and colorless.

Just ten breaths later, Li Yan had returned to the rear of the battlefield of the Tianli tribe, thousands of miles away on the top of a mountain, where three elders were sitting cross-legged on the top of the mountain.

As soon as Li Yan's figure appeared, the three of them opened their eyes at the same time.

"Fellow Daoist Li, is this good?"

The First Elder's voice came immediately. At the same time, the Second Elder and the Third Elder also looked up at Li Yan. Their eyes kept looking at Li Yan, and they were already very surprised.

When Li Yan left just now, something seemed to light up in his hand, and then the aura on his body dropped rapidly. Soon, it would be difficult for even the three of them to detect Li Yan's existence if they were not paying attention.

"Concealed high-level magic weapon!"

This idea flashed in the minds of the three people at the same time. The magic weapon that conceals the aura on Li Yan is really good. At least the monks in the early stage of Nascent Soul cannot detect him.

How did they know that the flash of light in Li Yan's hand was just something he did deliberately? He didn't want the other party to know his trump card.

Therefore, he did not use the "Stealth and Night Hiding" technique to its extreme, nor did he use the "Tide Ebb" technique at the same time.

Li Yan guessed that a battle between low-level wind beasts and mortal warriors had just ended here, and those fourth-level wind beasts would not pay too much attention here, so as long as he was careful, he would not attract the attention of the fourth-level wind beasts.

As he guessed, this place is a battlefield for mortals, and the various auras are too mixed, so the monk's spiritual consciousness will not stay here for a long time, and will only scan here from time to time.

With Li Yan's powerful spiritual consciousness, he believed that he could sense whether a fourth-level monster was coming to investigate.

"Well, that's enough. We'll know the effect when the wind beast attacks next time!"

Li Yan nodded.

"This...are those poisons ready?"

The second elder asked almost exactly the same question as the first elder, showing the strong doubts in his heart.

It only took Li Yan more than twenty seconds to come and go, which also included the time he spent searching for a place to apply the poison ahead.

The scope of that basin is not small. According to the normal poison deployment procedure, the poison should be deployed in the main areas where the wind beast passes through after observing the terrain.

If they use their methods to lay out a simple formation, of course it won't take even this time, but if they want to lay poison in the formation, they need to adjust the fusion balance between the formation and the poison, etc.

It's not just a matter of throwing out a few bottles of poison. That way, the poison will spread in all directions instead of being limited to the formation. Not only will it affect the Tianli people, but it will also continue to weaken as the poison spreads.

But just now Li Yan only walked around in the basin, and didn't see him take out the porcelain bottle, nor did he see what he sacrificed. Then he flew back again. The three of them didn't notice how Li Yan used it.

Poisonous.

"Just wait and see what happens!"
