Said,

He gave Xu Yuan a meaningful look.

Xu Yuan ignored him.

After a cup of tea, the fluorescence in the tree hole suddenly fell silent.

Xu Yuan saw this and asked:

"Success?"

The remnant soul of the saint shook his head:

"This formation requires a soul key to activate. If it is activated forcibly, it will cause the formation to backfire."

"."

Xu Yuan's eyes became a little strange.

It is possible to set a password when starting the formation in this world of cultivating immortals?

After thinking for a moment, I felt relieved.

The importance of the formations at many key locations in this world is almost equal to that of nuclear bomb launchers in previous lives. It would be unreasonable if only one person could operate such a central location.

After pondering for a while, Xu Yuan whispered:

"Old man Luo, try controlling my body."

"Huh?"

The saint's remnant soul hesitated, remembering the cherry blossom that had just melted into the boy's eyebrows, and directly got into the soul ring with a smile.

Silence for a second,

Xu Yuan waved his hand and the formation was activated again.

After practicing the technique of a cup of tea, a cherry blossom mark suddenly appeared between Xu Yuan's eyebrows.

When this seal appeared, the formation seemed to have opened up a key link, and there was a buzz!

The next moment,
Chapter completed!
