After Being Slandered by the School Belle and Expelled, I Practiced Gu and Cultivated Demons

[Protagonist turns dark] + [Demon Villain] + [Both Good and Evil] + [Decisive Killing] + [Never the Virgin] + [Heavy Mouth Hunting] = [I don't know what it is either] In the Yi'an world, any mortal whose Dantian strength reaches the standard can open up the Purple Mansion through the annual Open Source Ceremony Array. After configuring the natal source soul, he can become an otherworldly practitioner. Eighteen years have passed since then, and Gu Ansheng has always been the strongest person in the mortal Dantian of Yuanshi Academy. If nothing else, he will have a bright future after the Open Source Ceremony. But with one week left before the Open Source Ceremony, an accident happened. The college's number one beauty actually slandered Gu Ansheng in public for a truth or dare game, causing him to die. And her cultivator fiance was even more indiscriminate, destroying Gu Ansheng's Dantian with one palm, completely disqualifying him from participating in the Open Source Ceremony. The college also expelled him on this basis. Despaired, Gu Ansheng returned to his old house in the mountain village and unexpectedly discovered that his dead father turned out to be the last patriarch of the Gu Xiu Ming family, the largest evil cultivator family in the Yi'an world, and he also left himself several powerful legacies. After taking over the position and legacy of the evil cultivator clan leader, Gu Ansheng changed his original name to Ming Ansheng, used the space magic weapon Gu Soul Cup to open up a "vessel mansion", and deployed six million-year-old Gu souls in the first layer of the sky. From then on, he sacrificed the flesh and blood of hundreds of millions of living beings, and used Gu to prove the Tao!
