I have a Mansion in the Post-apocalyptic World

After the nuclear war, ruins stretch across the landscape in the apocalypse. If you accidentally survived on the wasteland, then you must be ready to face the endless hunger, ceaseless dangers, the mad zombies at night, and the peculiar mutant creatures that are the aftermath of constant radiation. But for Jiang Chen, this place is heaven. Mansions standing tall, luxurious cars parked on the street, high tech products and gold abandoned everywhere. What? You were the president of a game development company before the war? You were responsible for the development of the 3D virtual reality online multiplayer game? Well, that’s great, why don’t you come work for me. Your salary is two pieces of bread a day. iPhone? Ultra thin design? Don’t you see that the phone I invented is thinner than a condom? Aircraft carrier? Fighter jets? Oh, I have those things as well, but they are designed for space combat. Watch the story of Jiang Chen, who possesses the ability to travel through space and time, as he witnesses the creation of an empire stretched across space and time...

Ultrasonic Fence

編集者: Rainystars

Last month, the research institute at the colony and Celestial City lab determined the appropriate frequency through collaboration.

The modified seismic wave excitation device would continuously transmit seismic waves of twelve different frequencies to create a "blank domain" with a range of ten kilometers underground. In this blank domain, Devil Worms would be unable to determine their direction and unable to distinguish the surrounding and surface conditions, while also experiencing strong discomfort.

The experts in the lab named the invention Ultrasonic Fence.

Twelve seismic wave excitation devices were deployed around the colony to form an ultrasonic fence. Now, with the colony as the center, the ten kilometers radius became a restricted zone for Devil Worms.

Thanks to this, the stagnant work around the colony finally restarted.
