As Lin Su took the initiative to suggest that his pet beast with lie detection capability test him at any time, the people in the room started to trust him a bit more.
Before coming, they had also thought of doing this but felt it awkward to bring up the matter.
Because such lie detection is deemed offensive and rude, typically directed at weaker individuals who can be offended without repercussion to extort some truth about certain matters.

If they had raised the matter and failed to buy the Secret Technique, but instead made an enemy of Lin Su, that would have put them in a difficult position.
Now that Lin Su had brought it up himself, there was no problem.
Confronted by dozens of special pet beasts with lie-detection abilities, Lin Su was not the least bit flustered.
