The Age of Iron and Fire

A car accident plunged modern-day young man Yu Chuan into darkness. When he opened his eyes again, he discovered that he had transmigrated into an unfamiliar medieval world and become a commoner boy named Allen. With nothing to his name, he relied on modern knowledge and Allen's memories to make his way up from the bottom, carefully planning each step. Amidst a world torn by war and tangled in power struggles, he gradually rose to prominence, writing his own legend across this vast medieval world.

The male lead, Allen (Yu Chuan), is an ordinary office worker from the 21st century. He had been living an unremarkable life until a car accident unexpectedly sent him to the Middle Ages, where his soul took over the body of a 13-year-old boy named Allen. The boy was physically weak, so in the early stages, he could only rely on modern knowledge and intelligence to overcome one challenge after another.
