Zhou Wen picked up the Buddha plaque in Xiao Si's hand with his sword. For Xiao Si to use the Buddha plaque against Zhou Wen despite having seen his strength, it was likely that the Buddha plaque had extraordinary strength, so Zhou Wen was rather careful.

If he was not careful, this tiny Buddha plaque might become his death warrant.
Zhou Wen carefully sized up the Buddha plaque and couldn't see anything amiss. All he felt was that there was some invisible evil aura lingering on it.
However, this evil aura didn't seem to have any effect.
