Zhang Yi said he could only create pills for warriors of the realm core revolution, so Jin Lingxin was not very hopeful with him, but if Zhang Yi could create a perfect grade pill for warriors of the core revolution realm it was obvious he could create top grade pills for spiritual sea realm warriors.
But Jin Lingxin understood why Zhang Yi did this after all Zhang Yi was a great alchemist master who had no sect and no organization, so if he could create pills for warriors of the realm core revolution he would just be respected by all.
But if he could create pills for warriors from the realm of the spiritual sea he would have a great risk of being forced into some great sect or organization, so Zhang Yi had to lie like that to protect himself.
