Siheyuan: A Two-Way Portal from the Start, Connecting to the Apocalypse

A certain island nation dumped nuclear-contaminated wastewater, triggering the apocalypse.

At the brink of life and death, Zhang Xiao activated the Ultimate Homestead System.

He successfully opened a twin portal to a courtyard compound.

Not only could he take shelter in the courtyard world, he could also return to the original world to fight monsters and upgrade his homestead.

"System mission: Kill Granny Deaf!"

"Reward acquired: Basic physical enhancement."

"Puppet acquired: Granny Deaf!"

"Granny Deaf: Necromancer."

Upgrade the Ultimate Homestead and make it the only refuge in the apocalypse.
