The several large formations outside the Huanguang Cave just now were indeed mysterious and unpredictable.

But the strength itself is not strong.

Otherwise, it would be impossible for Xiao Yi to break through it.

The Master of Tianji Palace smiled and said, "The Five Elements Magic Formation is one of the most powerful formations in my hands."

"The Flowing Light Sunless Formation is one of the strongest formations I have in my hands right now."

"Although I have indeed suppressed the level of the formation by many levels, the fact that you can break through it means that your attainments in the formation are not low."

"One of the most powerful formations?" Xiao Yi frowned slightly.

The thought of being trapped in the formation and being desolate for thousands of years still made him frightened.

If that was not a test from the Master of Tianji Palace, but a strong man of this level really wanted to kill him, I'm afraid he would be dead by now.

And he died extremely miserably.

Within the formation, in a blink of an eye, the world and the world were desolate.

Outside of the formation, it only lasts for an hour or three.

If the power of that formation had not declined, I am afraid that even veteran legendary powerhouses such as Elder Jiang Yue would die within a few breaths.

"If you want to learn, I can teach you." The master of Tianji Palace smiled, but this smile looked a little different.

Even a little...obscene.

"What's the price?" Xiao Yi asked directly.

After dealing with Senior Luo once, Xiao Yi had already predicted that the master of Tianji Palace would open his mouth like a lion.

There is no free lunch in this world.

In exchange for the Ten Thousand Poisons and Ten Thousand Dao Fruits with Senior Luo, you need 15 cave treasures.

Practicing formations from the Master of Tianji Main Hall obviously requires a price.

However, the Master of Tianji Palace smiled and said, "The price? Nothing."
