After selecting three notebooks, Zhang Ruochen left the sword pavilion and returned to the square below the White Stone Sacred Cliff.

It was night, and there was a bright moon hanging in the sky. There seemed to be an invisible force pushing the clouds away, revealing a dark blue sky.

Zhang Ruochen glanced at the altar in the center of the square, and a strange light flashed in his eyes.

The altar was thirty feet high and was made of jade stones. Each jade stone was engraved with mysterious patterns, which emitted a faint light under the moonlight.

Zhang Ruochen walked towards the altar, placed a hand on one of the jade stones, released his mental power, and began to explore.

In the world of Wood Spirit Ruins, Zhang Ruochen saw a heaven and earth altar.

Therefore, he still has some understanding of the Heaven and Earth Altar.

As the spiritual power circulated on the altar, Zhang Ruochen checked all the inscriptions on each piece of jade, and thought to himself, "This altar has no similarity with the Heaven and Earth Altar. Could I have guessed wrong?"

?No……"

Suddenly, Zhang Ruochen noticed something quite incredible.

His spiritual power flowed on the surface of the altar without any abnormalities.

However, when his spiritual power surged towards the bottom of the altar, he immediately lost contact and disappeared without a trace, just like a stone sinking into the sea.

"Could it be that... there is something else underneath the jade altar?"

Zhang Ruochen was shocked in his heart, and immediately used his mental power to continue exploring, and soon found an entrance in the northeast corner of the jade altar.
