Zombie: After removing the impurities, Uncle Nine begs me to come out of seclusion?

Having traveled back to the Republican era, Su Feng thought he could live a peaceful and comfortable life.
Unexpectedly, the town was called Renjia Town, and there was a mortuary run by Uncle Jiu at the entrance of the town.
At this moment, Su Feng was numb.
What to do? In this degenerate age, encountering ghosts and zombies means certain death.
Fortunately, there's always a way out. Su Feng activated the most powerful "AI" program he had developed himself.
Eliminate all defects and deduce the flaws in everything.
And so, Su Feng took off.
"Ding! 10086 bloodline defects detected in your body. Eliminate all defects and advance to the Innate Body!"
"Ding! Flaws detected in your talent. All flaws have been removed, and your comprehension has been upgraded to the 'Heaven-Defying' level!"
"Ding! We have detected that you are watching Dao Fa Yuan Hui. All flaws have been removed. Congratulations on comprehending the Five Thunder Orthodox Method!"
"Ding! Your white fox pet has been detected to have a trace of the bloodline of a nine-tailed celestial fox. All defects have been removed, and it has been promoted to a nine-tailed celestial fox!"
