In 2030, the earth was colonized by the "Void Federation", a technological civilization from another dimension, and humans were reduced to third-class citizens. Ye Fan was originally just the owner of an abandoned house in Changfeng Technology Factory, but accidentally awakened the "Parallel Universe Technology Inheritance System" and could obtain the black technology inheritance from Tony Stark in different time and space.
The system releases the ultimate mission: to establish a human technological empire, overthrow the rule of the Void Federation, and avenge his father who was killed by the Void Federation. Ye Fan discovered that his father's death was not accidental, but was assassinated because he had mastered the weaknesses of the Void Federation. The murderer was the Xingchen Group, the Void Federation's agent on earth.
Starting from a small factory on the verge of bankruptcy, Ye Fan unlocked various black technologies through system rewards: anti-gravity engines, quantum computing chips, nanorobots, etc. On the surface, he was dealing with the Star Group, secretly developing an underground technological network, and cultivating a human resistance army.
As his strength increased, Ye Fan gradually penetrated into the Void Federation and discovered that there were also factional struggles within this alien civilization. He cleverly used the alien political whirlpool to sow discord, and at the same time secretly united with other oppressed lower-civilized races.
In the end, Ye Fan not only wants to establish a human technological empire on Earth, but also burns the flames of war to the Void Federation itself, completely crushing this oppressive civilization and avenging his father and the entire human race.
