Song Hanyu recalled that when Hu Yixiao arrived in the air, William had revealed his identity as the Scarlet Chop's undercover agent.
At that time, Song Hanyu had two doubts in Esmeralda.
At that time, William did not really prove the identity of the undercover agent of Red Slash, but he said it. It did not fit William's steady character at all.
Song Hanyu was thinking that there should be two possibilities for William.
He still had real evidence in his hand that could completely smash Red Slash to death, but he didn't say it out loud.
Another possibility was that he deliberately said it to guide the whole situation.
Now it seemed that both of their guesses were right!
When Red Slash tried to assassinate him, William deliberately left the Long-living Demonic Lotus on Red Slash's body.
The next day, Red Slash appeared. Naturally, William could sense the Long-living Demonic Lotus on his body. Therefore, William immediately confirmed that Red Slash was the assassin!
