The Extreme Yin King and Mysterious Character Card's Evil Ghost possessed a cold sneer in their eyes all along, displaying an attitude of arrogance as if they held all the cards and looked down on everyone.
For the rest of the kings, apart from Du Qing who looked worried, the rest seemed delighted at the disaster that was about to occur and were prepared to enjoy the show.
"Xiao Mu, I will lend a hand when necessary. However, the Extreme Yin King is too powerful, and the forces behind the Mysterious Character Card's Evil Ghost are too great. It would be best not to provoke them if you can avoid it," Du Qing transmitted his voice again, seriously cautioning Xiao Mu.
"Thank you!"
Xiao Mu could decipher the implied meaning in the Extreme Yin King's words.
As they both originated from the Human World, Du Qing would assist when necessary, but only when necessary. If it got too dangerous or too troublesome, Du Qing would likely opt to sit back and observe.
