Eternal Ancestral Spirits

After my sudden death, my soul attached to my family tree became the ancestral spirit of the Chen family. On the day when the family was about to be exterminated, the genealogy shone brightly. I use product thinking to run the family: improvement of spiritual fields, deduction of martial arts, awakening of bloodline... The family has risen from the humble beginnings and has reached the top of the Nine Realms. But the corpse of a god and demon underground, the invasion of heavenly demons thousands of years ago, and the memories I forgot—all are telling me: My time travel is a layout that lasts for thousands of years.
