​​Chapter 1​​

August 21, 2080. I had a huge fight with Chen Jiashu.

I stormed out into the blazing sun and slammed the door behind me.

That same day, a radioactive light called Gamma pierced the ozone layer and swept across the globe. Life began to mutate.

At first, it was plants. Overnight, they grew primate-like teeth and started feeding on insects and small animals.

Then, carnivorous animals began regressing to primitive forms. A simple chain could no longer restrain their wild instincts. News reports of pets killing their owners became commonplace.

Just when everyone thought the mutations had stopped, the Joint Department of the Rebirth Gate Organization issued a new statement:

Dear Fellow Earthlings,

We regret to inform you.

According to the latest medical findings, individuals exposed to Gamma radiation outdoors on August 21, 2080, will undergo irreversible mutations in the future.

We refer to this disaster as ""Rebirth Day.""

To confront this unprecedented catastrophe, we have established ""Rebirth Gates"" in every nation. We urge those who are ""reborn"" to come here before their rationality is completely extinguished.

This is not a matter of individual survival. It is about closing Pandora's box for the fate of humanity."
