Mo Wuji's flying ship was much faster than Cen Shuyin's, but due to Cen Shuyin's relentless pursuit, Mo Wuji was discovered her soon after he left the Heaven Seeking City.
Initially, Mo Wuji even thought that he was being chased by some Lei Clan dogs and he was intending to retrieve a laser cannon and send a shot over.
However, he soon discerned that the flying ship was controlled by Cen Shuyin; she was standing conspicuously at the stern of the ship.
This left Mo Wuji curious; he didn't know what business Cen Shuyin had with him.He did not think that Cen Shuyin would know that he was Rogue Cultivator 2795. Even though she had applied for a contribution point token together with him, their interaction was merely during the application. At the very most, she helped make the application process easier. She definitely didn't see what was written on his token, much less know that he was Rogue Cultivator 2705. Unless Cen Shuyin was like him and possessed strong spiritual will.
