Tang Shaoyang arrived on the thirteenth floor straight from the third floor, and he was less excited to explore the tower after what happened on the third floor. He did it not because he liked it, but because he deemed it was a necessary step if he wanted to absorb the Adventurer Guild.
The Adventurer Guild was different from all the natives he saved from the tower or dungeon. They were not in a desperate situation where they needed to get out of the tower or look for protection from him.
That was what made the guild different. They were not in a desperate situation, and they would move based on their benefit. If betraying him gave them a benefit, then they would not hesitate to do so.
