Signing In for 100,000 Years, the Whole Clan Begs Me

Cast out of the Shaolin temple, Lin Yuchen falls into the Burial Immortal Cliff, where he signs in and receives the complete memories of a demon emperor ancestor from 100,000 years ago. From then on, he is no longer a bullied waste, but a walking encyclopedia of cultivation, an 'living ancestor' who outranks all the elders! When the clan holds an ancestral worship ceremony, he strolls into the ancestral hall, and with each sign-in, an ancestor's spirit manifests. Everyone kneels in worship, and the clan leader's face turns ashen: 'You... who exactly are you?' Lin Yuchen says calmly: 'I am your ancestor.' The current cultivation methods are all watered-down versions; only what he signs in is the true orthodox path to the Dao. The debts of 100,000 years, he will collect one by one, personally. — Description from novelcodex.org
