Zhuang Yifan was the president of the Golden class academy Alliance, and he was a master at the late stage of earth-opening, but even so, he only managed to gather 30% of the materials for the earth strengthening pill. One could imagine how difficult it was.
The Shennong cauldron could be used ten thousand times, but the ingredients could only be used three times. This was the reality. If one failed three times, it would be equivalent to a failure.
Since the ingredients Zhuang Yifan provided were a bit excessive, Lin Yi only had two sets left, not even three.
He didn't dare to put all of them in at once. Even if the alchemy curve had been adjusted, no one knew if it would succeed before the second result came out. If there was a need for further adjustments, and he foolishly threw in all of the alchemy materials at once, that would be a joke.
