How Long Have I Been Living in the Demon Sect Water for Several Lifetimes?

Long Buquan accidentally traveled to the Demon Sect in a different world, surrounded by dangers. Fortunately, he awakened to the survival system [the longer you live, the richer the rewards, and you can get additional rewards if you avoid crises]. In front of the alchemy furnace at the gate of the Demon Sect, Long Buquan escaped the danger of being refined into a human elixir for the first time, and received an extremely generous reward - the heaven-level skill "Six Paths of Reincarnation and Nirvana", and thus began his magnificent six reincarnations! In the first life, the hero was saddened by beauty. He was deceived by the elder sister and his Yang Yuan was taken away and he died. (Survive for three days, and the time reward is only one level of skill improvement) In the second life, he practiced hard skills and turned against his senior sister. In the end, he was stabbed in the back by his master. After cultivating the first ray of soul, he was plucked from the peach, and died in a state of confusion. (Survive for three years, and the time reward is the mysterious magic weapon "Dark Pearl") In the third life, he changed his sect, became a disciple of the peak master, killed his master, abandoned his bottom line, climbed up by any means, and finally completed a foundation-building overhaul. However, he was still allowed to seize the Tao foundation by the trusted peak master, refine the Tao elixir, and die. (Survive for thirty years, time reward: Earth-level magic weapon "Ruyi Golden Sword") The fifth and sixth lives... Long Buquan finally achieved the holy throne. Looking back on the past, there were actually no enemies along the way, but rather "good teachers and helpful friends".
