Chu Yunfan looked at Kong Buyi with a faint smile. Obviously, Kong Buyi didn't want him to continue talking. After all, this antidote pill was developed with great difficulty. If Chu Yunfan continued to talk and made everything public, it would be terrible.
Although Chu Yunfan didn't have such strength, Kong Buyi thought that he did.
Because of this, he didn't let Chu Yunfan continue. Since Chu Yunfan already had such strength, there was no point in continuing to make things difficult for him.
However, he also wanted to know who exactly Chu Yunfan was. One had to know that when he took the senior alchemist assessment, he was trembling with fear. In the end, he passed the examination with great difficulty.
Back then, he had more or less relied on luck. He had not been present with medicinal pills that were particularly difficult to identify. Otherwise, he might not have passed.
He couldn't be like Chu Yunfan, who could easily complete all the tests.
