The Ancestor of the Xianmen Xianyu Became the Devil's Son-In-Law

Liu Fang, an ordinary security guard who stayed up late on duty, woke up and transformed into Ye Xiu, the powerful ancestor of the Ziyun Sect who has been practicing for thousands of years. The original owner was a giant of the righteous path, capable of wielding a sword, making elixirs, preaching and defeating enemies. He should have been respected by thousands of people, but what Liu Fang took over was an empty shell with inner demons backlash and all his cultivation lost. The spiritual power that used to move mountains and seas was gone, his Dantian was empty, even normal walking was difficult, and even the memory of the original owner was incomplete and vague, hiding something strange. Before he could adapt to his identity as an ancestor, and he didn't know how to face a group of awe-inspiring disciples and his disciple Su Li who was extremely attached to him, the sect received shocking news - the demon sect's army was pressing on the territory, and the sect-protecting formation was in danger. The entire sect was looking forward to his ancestor coming out to control the situation. A modern social animal traveled through time and became a peak ancestor, but he became a scumbag with no cultivation, surrounded by powerful enemies. What should he do?
