They all knew that the method to approach the giant tower was to avoid using Spiritual Essence.
Without using Spiritual Essence, their palms could adhere to the giant tower.
And once they adhered to the giant tower, they still couldn't use Spiritual Essence, or they would be repelled.
Their Sacrificial Refining Method was greatly restricted without being able to utilize Spiritual Essence.
They looked towards the gaunt middle-aged Cheng Siyao.
Cheng Siyao's face was solemn.
He had already discovered the anomaly of this giant tower, which was different from his previous perception.
Earlier, he had tried to refine it, but although he didn't succeed, he was close.
After all, having attempted to refine it, there should have been some lingering traces left.
But there was no trace of spiritual remnants on this giant tower, as if it were a brand new tower.
He faintly felt this way, but reason suppressed this thought.
In his opinion, it wasn't possible there was another tower.
