He knew that Ye Suhuan had evidence proving that she was indeed Feng Wuyou.
At the same time, Xiao Jinyan also blamed himself for overlooking this detail.
In the past, when he was with Feng Wuyou, they held hands countless times, yet he never noticed the mole under her wrist.
There was also the broken moon; he had seen Shen Chuwei pull out the dagger, but he always thought it was just an ordinary dagger.
He suddenly remembered that in the Xingmiao Clan, Shen Chuwei had also pulled out the dagger to deal with Ye Suhuan who tried to kill him; it was just that due to the urgency of the situation at the time, he did not take note of the appearance of the dagger.
Ye Suhuan probably saw the broken moon then, which was why he further confirmed that she was Feng Wuyou.
