Elder Huan Kong didn't answer, but his meaning was very clear. Yes, you are asking for too much!
"Too much? I don't think it's too much at all. Just calculate how many people from Thousand Caves Door have achieved enlightenment through debating with me," Cao Zhen said, beginning to tally with his fingers. "At least one or two... about ten people, right?"
So many people, all of them Cave Masters, have achieved enlightenment because of me. How much has the strength of your Thousand Caves Door improved thanks to their enlightenment?
Could it be that Elder Huan Kong believes that the enlightenment of a Cave Master from your Thousand Caves Door is not as valuable as those Spirit Grasses?"
"I did not say that... Fine, we can provide the medicinal herbs that Peak Master Cao wants, but we do not have the Traceless Herb; Peak Master Cao will need to find another way for that."
