The Wuchang's information was very helpful, but he was as powerful as a Half-Saint, after all. He was definitely tricky and calculative. No one could discern if he was telling the truth or not, or if he wanted to lead them all into extreme danger.

Zhang Ruochen later released the other Wuchang from the Ruyi Treasure Bottle. Blackie took her elsewhere to continue interrogating her. They could make a decision after comparing the information from the two Wuchangs.
At the same time, Zhang Ruochen returned to the side of the river. He investigated the corpses on the bank while observing the flowing river. He seemed to be searching for something.
"Something's amiss. It really is."
Then he sat cross-legged on a corpse and closed his eyes. He released his Spiritual Power, searching the spatial structure here with all his power.
