Zhao Hai took a look at the hall. This Hall was not an ordinary Hall. Although the entire Hall looked ordinary and seemed to be made of stone, these stones had all been refined using the method of refining artifacts. They had been carefully refined and could be said to be magic artifacts that contained the energy of the Shadow Realm.
However, these things were of no use to Zhao Hai. He took a look and opened the door of the hall. Zhao Hai saw the situation inside the hall. The ground was filled with arrays, the table, the small chair on the table, and the four sacred artifacts on the chairs.
When Zhao Hai saw the four sacred weapons, he couldn't help but smile. Then, he waved his hand. Four balls of green light flew out of the four sacred weapons and landed in his hand. Then, they disappeared. Zhao Hai raised his head to look at the four sacred weapons. They were still standing there motionlessly. They were Dharma weapons, so they naturally wouldn't move.
