While practicing Spirit Refinement, Ling Han encountered countless problems and obstacles.
Ling Han was a proud person, and he would only seek help from others if he truly couldn't resolve a problem by himself. Even without Alchemist Zi Cheng's words, he would have still done his absolute best to resolve his own problems.
Three months passed in the outside world, and this corresponded to over 20 years inside the alchemy room. During this time, Ling Han also overcame several flare-ups from the Black Murderous Curses. He had overcome them in an extremely calm and composed state. In fact, this allowed him to discover some slight secrets of the Black Murderous Curse.
Finally, Ling Han left for the first time, heading to the fifth level to seek help from Grandmaster Zi Cheng.
Because Grandmaster Zi Cheng had already notified the others, Ling Han was able to reach the fifth level unobstructed.
