Hai Huang's laughter was filled with unconcealed pride and joy. A thousand years ago, his ancestor had returned from the battlefield of gods and brought with him a large amount of information about the ruins of the Tian Xuan sect. One of them mentioned the situation on the eighth level of the Tower of Trials.
Of course, these hundreds of ghost generals were not sealed by his ancestor. With his ancestor's divine transformation realm strength, he was completely unable to do so.
That ancestor of his had only obtained some information from the stone door and then found a way to unseal it.
As for whether or not he could control these ghost generals, his ancestor was not 100% confident. Everything was just a guess. What Hai Huang did not expect was that things would go so smoothly.
