Tai Sui's attack needed to hit someone to produce effects. As the saying went, breaking ground where Tai Sui presided required touching Tai Sui. Although Zhou Wen didn't need to break ground, he had to touch Tai Sui.
Zhou Wen had previously experimented. The stronger Tai Sui's attack was and the more attacks it delivered, the greater the effects of the Tai Sui God symbol.
Zhou Wen didn't feel any pain when he struck his head with Tai Sui, but the feeling of having lost control immediately weakened. The automatic strengthening of his muscles also decreased significantly.
It works! He was immediately delighted as he smashed the club on his head again.
The main reason was that Tai Sui's strength was too weak. Zhou Wen could use more strength if he did the smashing for it. On the other hand, holding Tai Sui would also affect him to a certain extent.
