After spreading his senses over more than half of the city, Liam rose into the sky.
He knew that the assassins are still in the city and that they would be positioned between a location close to Master Han store, and the inns he had stayed in. And as their luck would have it, those locations were within range of Liam's senses.
The reason why Liam flew into the air was to make a statement and attract the attention of the assassins. He knew that they will definitely react when they sense someone spreading their senses over the city, and if they are to see him floating in the air, openly announcing his presence, they will come out of their hiding holes and attack him.
Liam's action of spreading his senses over the city was disrespectful and would offend other cultivators, but he really doesn't care, as it's the only way he can achieve what he want.
