Wang Xing transmigrates through an artificial wormhole in the name of scientific progress and arrives in an ancient parallel world. All the supplies he brought vanish into the vast universe, leaving him with nothing but his bare body:
To survive, he takes on grueling labor and serves as a constable. His extraordinary abilities earn him the chance to take the military examinations, where he comes out on top. This wins him the emperor's favor, and after distinguishing himself in several battles, he is sent west to repel a Tubo invasion. Thus begins his campaign to conquer the realm.
This time-travel novel suits my taste very well and is worth recommending to everyone.
The plot is exciting and reasonable
