End of the World, Starting Protagonist Template?

At midnight on December 22, 2012, the end of the world predicted by the Mayans came as expected. Zombies are rampant and order is broken. Su Yi, a 17-year-old orphan, became the holder of a "god" after accidentally swallowing a mysterious golden apple. There is a soul in his mind who calls himself "Bai Ze", the god of the Shang Dynasty, and his body has gained the "quantum ghost" power that can ignore physical obstacles. However, Su Yi has no interest in becoming a god or saving the world. His only thought was to find his sister, Su Yu, in the completely occupied city. But when he found Su Yu in a university dormitory surrounded by zombies, he found that what was more dangerous than zombies was the human heart that suddenly deteriorated in a desperate situation... And the truth behind this doomsday seems to be far more than a virus disaster.
