Eighty-five years ago, human beings found a huge white humanoid object on the coast of the North Sea, which caused a huge sensation at the time, and the Mohists sent people to transport this object to Jialan overnight to carry out research.

One noon, a staff member fell asleep touching a human object, and in her middle of sleep, she found herself entering a world completely different from the outside world, with vast mountains and rivers, sun, moon and stars. He walked aimlessly through this world, thirsty to drink the water of mountain springs, hungry to eat wild fruits from the trees, as if everything here was real.

Outside, he was unsteady on his feet, and fell to the ground with a slam of time, only to realize that everything he had just opened was just a dream. The staff informed the researcher of his experience, and the researcher followed his example and touched the humanoid object, and their mood gradually relaxed, and they entered the dream they had just lived.

Later, it was suggested that it would be better to build a virtual space with this object, and this proposal was fully approved, and the mind of the spiritual master infiltrated the humanoid object, modifying the environment in the dream and turning it into a real game world

Later, people found that they didn't actually need to touch its body, as long as their mental fluctuations were similar to it, even if they were thousands of miles away, they could enter the virtual space, and Mohist researchers relied on this principle to invent a helmet that could regulate mental fluctuations, as long as they wore it to relax their mood, they could enter the virtual game world

The principle of the anti-vector thruster is to first pump out the gas, and then use the ether to accelerate the abyss and then eject it, and propelle the aviation airship with its reaction force
