Traveling Between the Two Worlds, I Point to the Science and Technology Tree in Dawei

Death is not the end, but the beginning of another life. Chen Yuan did not expect that a car accident would turn him into a time traveler who could die repeatedly. In modern times, when he was on the verge of death, he opened his eyes and became Chen Yuan, who was so hungry that he gnawed tree bark during the Wei Dynasty. He was beaten to death in ancient times, and was "resurrected" in a modern hospital bed with enhanced strength. Antibiotics in his left hand, sweet potato seedlings in his right hand, and the "Tiangong Kaiwu" memory chip in his arms - he became the weirdest bug in the two worlds. The Great Wei Dynasty: Starting from a sweet potato seedling, waterwheels, gunpowder, steam engines... He personally ignited the fire of civilization, from hungry people to emperors, but he did not know that he was rewriting the entire history of mankind. Real world: The Anomaly Investigation Bureau has focused on him, and the mysterious organization wants to dissect him, but his body is jumping repeatedly between two time and spaces - if he cannot find balance, he will be brain-dead in two worlds at the same time. When the dragon flag was planted on the foreign continent, when the star map unfolded in his hands, high-dimensional beings finally cast their gaze: "Experimental Subject No. 079, You are beyond the observation range." Chen Yuan smiled: "Sorry, I took over this petri dish." [Shuttle between two worlds] [Revival of civilization] [The mastermind behind the scenes] [Two lines of salvation] "Others rely on the system to travel through time, but I rely on dying repeatedly."
