Dark Abyss: World Controller

I am Chen Mo, 28 years old, the main programmer of the game "Dark Abyss".
I hid in the mountains half a year ago to write a novel. When I woke up, I found that the world had collapsed - games invaded reality, monsters were rampant, and copies were everywhere.
The whole world is in panic, and I know that I built this system using abandoned military protocols, and I still have backdoor permissions at the bottom.
I have no team or equipment. I am only connected to the nerves of the system. Every time there is a change, the pain is like a knife cutting my body.
The armed forces hunted "system related persons", but I became the only one who could shut down the disaster.
They are looking for a savior, I just want to live. But as long as I still hurt, I could still find my way home.
