"Wifey, when do you plan to help Uncle advance to the Golden Core realm?" Mu Tianyan suddenly asked.
Lu Zijia pondered for a while and said, "Let's wait a while longer. To advance to the Golden Core realm, one has to go through the lightning tribulation. Uncle hasn't recovered for long. Let him temper for a while more."
As one's cultivation level increased, it would become more and more difficult to advance. Some cultivators might not be able to break through from the peak of the Foundation Establishment realm to the Golden Core realm in their entire lives.
Not only did one need the help of pills to advance to the Golden Core realm, but he also needed a strong physique. Otherwise, the chances of successfully advancing to the Golden Core realm were very small.
Besides, once a cultivator failed the first time, it would be extremely difficult for him to advance to the Core Formation realm again in the future.
