In order to prevent Lin Yuan from being harmed by Origin Liquid, this reasoning seems quite justified.
Because every injection of Origin Liquid could potentially resolve a life-threatening crisis and save the lives of many more innocent people.
However, Zhou Bingbing had previously expressed her admiration, saying that although Lin Yuan had not been in contact with the Origin Body Technique for long, he probably could already withstand the erosion of Origin Marrow.
So for him, Origin Liquid really wasn't much of an issue.
Of course, it's not to say that there would be no harm...
But was this harm truly worth exchanging for half a Magical Treasure exchange merit?
Lin Yuan already had two Magical Treasures in his possession. Xie Tianyi might be just a minor character, but with a Qi Refining Realm's cultivation base and wielding a Magical Treasure, he could escape from the hands of Zhao Chengzuo, who was at the Martial Venerable level.
