I Am the Ancestor of the Family [The Demon Ancestor Is Always with You]

(Brain + System + Family + Single Female Protagonist + Time Travel + Boss) This is a book based on the mentality of an immortal cultivator, accompanied by the two demon ancestors of the demon clan, and an ordinary small family (the one who dominates cannot be said to be only a hundred million points strong) spanning several major realms. Li Lei traveled to the endless world of cultivating immortals, awakened the Immortality Billion Point Power System, and gave him a free chicken and a black dog as companions. I, Li Lei, don't want to bully others. I just want to take my two partners and my family to see all kinds of things in the world.
