During this time, he had mastered all the knowledge he had once learned, such as writing, playing musical instruments, calligraphy, painting, and most importantly, spiritual power and formations.,Chen Xi carefully reviewed all the historical materials and finally determined one point: history had already begun to change during the Warring States period four hundred years ago.,Qi can be cultivated by almost anyone, and the difficulty of tempering one's spiritual power has also been greatly reduced.
