Even if he has reached the level of half-level spiritual mastery, the secrets of these formations are still useful to him.

After all, the power of a formation cannot be made up for by strength.

What's more, no matter how strong the warrior is, even if he is a master of the Ancestral Divine Mirror, he may die under the formation.

One month.

Two months.

Three months.

Time passed day by day, and Li Feng and the others were moving as fast as ants.

By the time Li Feng and the others arrived at the center of the hall, it was already a year later.

This is the slowest speed since Li Feng explored the restricted area of ​​​​the secret realm.

At this moment, Li Feng finally understood why it took those powerful men hundreds of years or even longer to explore the restricted areas of the secret realm.

This also made Li Feng understand that the reason why Xueying and the others had only explored part of the Demon Palace for more than a hundred years. It was not that Xueying and the others were incompetent, but that they were facing various dangers and couldn't move as fast as they wanted.

However, although the speed was as slow as a turtle, neither Li Feng nor Changsun Shiming cared about it.

Because the formation pattern suspended in the hall is enough for them to gain a lot.

Soon, four years passed.

At this time, Li Feng and Changsun Shiming had almost forgotten the passage of time. While slowly moving forward, they understood the profound meaning contained in the formation pattern.

Until Li Feng encountered a five-color array pattern.

Before Li Feng could touch the five-color array pattern, the five-color array pattern automatically flew towards Li Feng and hit Li Feng's body.

"ah……"

Li Feng groaned as if he was hit hard and fell to the ground.

Of course, Li Feng was a clone and couldn't feel much pain.

However, just when Li Feng was about to stand up again, his expression suddenly changed.

"This is……"

At this moment, Li Feng's expression became extremely wonderful.

But at this moment, Li Feng didn't think much, he quickly sat down cross-legged and started running the Nine Heavens Heart Sutra.

Swish, swish, swish...

At this moment, Li Feng's body flashed with dazzling five-color lights.

"Um?"

The eldest grandson Shiming next to him sensed Li Feng's change and turned to look at Li Feng.
