Infinite Travel: from This Liar to the Dimensional Master

It was time for Meng Jun, who was confused at the beginning, to be thrown into "The God of Death". What golden finger? No! It all depends on the cleverness and toughness of people in society to survive. But he discovered that the skills he learned and the things he saved in each world can all be brought back to reality. As a result, the style of painting suddenly changed: he used his martial arts skills to clean up street gangsters, used interstellar technology to build roads in his hometown county, and relied on immortal cultivation formations to "plant" a protective forest at the border... While some countries were still fighting over a few resources, Meng Jun scratched his head and took out stacks of advanced technological blueprints and tons of rare materials from his own "backyard" (an entire private dimension). "Then what, my motherland, are you going to use this little thing first?" From a bastard to the master of the dimension behind the scenes, his life creed is just one sentence: Let your skin be your own, I will develop it quietly, and then I will give it to my family and my country!
