Xue Qinwen is a poor boy from the bottom of the city. He makes a living by doing odd jobs. He accidentally picks up a "double world carrying bag" in an abandoned factory and gains the ability to travel between the end of the world and modern times. During the day, he searched for energy chips and armor remnants in the wasteland world. At night, he returned to the modern black market and sold them at high prices, quickly accumulating his first pot of gold. He established a technology company to transform apocalyptic black technology into popular products for civilian use, and his wealth skyrocketed and attracted global attention. However, his sudden wealth has attracted covetous attention from many parties. The number one villain Wu Liang repeatedly set traps to seize his secret treasure, but was tricked by Xue Qinwen and the wealthy daughter Jiang Wanqi. Caught between technology and power, he not only wants to protect the balance between the two worlds, but also uncovers the ancient truth behind the carrier bag - a counterattack legend that spans the fault lines of civilization and is quietly rewriting the destiny of mankind!
