Reverse Cultivation from the Tribulation Period to the Qi Training Period

Other people's systems provide assistance all the way from the Qi training stage to the tribulation stage. My system is to reverse the breakthrough from the tribulation period to the Qi training period. [The reverse repair system has been bound, and the host can actively turn on the "nine days of reverse repair"] [The cultivation level of the Tribulation Transcendence Stage is obtained instantly after turning on it, and then it falls by one level every day, that is, from the Tribulation Transcendence Stage → Mahayana Stage → Combination Stage → Void Refining Stage → Divine Transformation Stage → Nascent Soul Stage → Golden Elixir Stage → Foundation Establishment Stage → Qi Training Period, the realms will fall successively. On the tenth day, the cultivation base will return to zero and become a mortal] [Every day that passes, all memories of the previous day will be forgotten. On the tenth day, all memories related to this system will be cleared, and the host's memory will also be corrected to when it first came to this world] [Every magic weapon, spiritual stone and other items obtained from others in each realm will be returned to the original owner on the tenth day] This system seems to be somewhat useful, but it seems to be completely useless!
