The "Nine Kowtows to the Heavenly Gate" was a secret cultivation art Luo Yan had obtained after deciphering the symbols of the Ancient Sword Shadow.
Judging from the information contained in this cultivation art, its creator believed that the heavens had nine layers, while humans had nine gates.
These nine Heavenly Gates remained closed within the human body, sealed shut without the slightest gap, blocking all of a person's potential.
If one could open the nine Heavenly Gates one by one, one's physique and body would be comprehensively enhanced, granting all kinds of Extraordinary Powers.
These nine gates, from lowest to highest, were Tai Xiao, Zi Xiao, Lang Xiao, Yu Xiao, Jing Xiao, Dan Xiao, Bi Xiao, Qing Xiao, and Shen Xiao.
However, Luo Yan did not know whether the information contained in those symbols was incomplete or whether he had yet to fully decipher it.
In any case, within the "Nine Kowtows to the Heavenly Gate," Luo Yan had only obtained the cultivation methods for the Tai Xiao, Zi Xiao, and Lang Xiao gates. Even so, if he could knock open those three Heavenly Gates, he would still gain tremendous benefits.
Take the lowest-level Tai Xiao Heavenly Gate, for example. Once Luo Yan knocked it open, his physique and body would receive a chance at comprehensive enhancement, greatly strengthening his defenses and reaching the state of being "Invulnerable to Blades and Spears."
Furthermore, when using the secret art, he would enter a state of "Inexhaustible Vitality." In this state, Luo Yan's vitality would become extraordinarily powerful. As long as an injury was not fatal, ordinary wounds would recover in an instant.
In this state, the speed of Luo Yan's Flesh Regeneration would reach a truly terrifying level.
The mere Tai Xiao Heavenly Gate already had such miraculous effects.
