"However, how did the formation-within-a-formation method be used three times in a row..." The next moment, Yun Feng frowned and murmured.

The technique of using the array within the array three times in a row is far more difficult than using it twice in a row. It contains some powerful secrets that he can't quite understand.

Huh-huh-huh-

Yun Feng's eighty-one spiritual thoughts were all concentrated and running rapidly.

Ten minutes...twenty minutes...thirty minutes...forty minutes...

"Not enough... I still don't have enough understanding. I can't comprehend the mystery..." As time passed, Yun Feng's brows became tighter and tighter as he murmured.

"Maybe it's time to upgrade your spirituality!" After a moment, Yun Feng sighed slightly.

Ever since he, Nie Yun, and Ouyang Shuo came to Misty Mirror Lake, the amount of powerful spiritual energy absorbed by the little blood-colored tower has grown rapidly. He has already accumulated enough spiritual fluid to allow him to spiritually grow to the early stage of the Eighty-One Immortal Emperor.

His spirituality has not been upgraded for a long time.

Eighty-one strands of spirituality are upgraded together, which will bring him super power of understanding and cultivation.

Originally, he planned to use this opportunity when he was promoted to the later level of Immortal Lord.

Looking at it now, it’s better to use it now.

Otherwise, he would never be able to comprehend this peak level five formation within an hour.

There are still many opportunities to break through the late stage realm of Immortal Lord. If you miss this fifth-level peak formation, there may not be a next one.

The super power of comprehension brought by the eighty-one spiritual upgrades will definitely allow him to fully comprehend this fifth-level peak formation.

"boom--"

After making the decision, Yun Feng no longer hesitated. With a thought, he immediately activated some spiritual fluid in his mind.

In an instant, eighty-one strands of spirituality in Yun Feng's mind were detonated.

Eighty-one strands of spirituality, connected end to end, spinning crazily.

Huh-huh-huh-
