My Mortal Ancestor, My Tribe Begged Me on Their Knees to Come Out of the Mountain?

I, Lin Chen, an ordinary social beast, woke up and became the legendary ancestor of the Lin family. Looking at the talented granddaughter Lin Qingxue kneeling in front of me with stubborn and desperate eyes, I panicked. [Ding, the family crisis mission has begun! [Main mission: Defeat powerful enemies and save the Lin family! [Side mission: Instruct the talented girl Lin Qingxue to revive her Taoist heart! In order to survive, I had no choice but to pretend. I thought it was a dead end, but I didn't expect... Lin Qingxue: "Ancestor's words are better than my hundred years of hard work! In this life, I am willing to use my ancestor's sword to kill all the villains!" The head of the family, Lin Xuande, said: "Ancestor just pointed a finger, and it is the foundation of the eternal prosperity of my Lin family!" Enemy Wang Batian: "Senior, spare your life! I am too blind to see Mount Tai, and I am willing to offer all my family property!" How can I keep this big lie when everyone regards me as a god?
