'Spiritual root transplantation' was not the only insane plan that Li Yao discovered in the Mausoleum of Chaos. For the entire day that followed, they had been exploring the southeast area of the second floor. They had found tremendous ancient books and jade chips inside the research rooms.

Most of the ancient books were made of natural materials such as unrotting spider threads or silk, which allowed the explorers to learn more and more shocking experiment plans. Li Yao also took the opportunity to hide a few critical jade chips. But he was truly stunned, his heart racing fast, after he read the jade chips in secret.

Right next to the research room of the 'spiritual root transplantation', quite a few associated research rooms were about methods to strengthen the spiritual root.
