Outside the Pass: the Tribulation of the Source Crystal

Outside the garrison cloud pass, black fog covers the sky. Seventeen years ago, only half of the entire army returned. He struck the city gate gong with his head and handed the infant to the guard. Seventeen years later, that baby grew up in a military camp and could only grind medicine, diagnose pulses, and wash people's feet. His name is Lu Chen. He doesn't know martial arts and doesn't know how to practice. His biggest wish is to follow his master and study medicine in the military. Until one rainy night, the master thrust a medical book into his hands: "Go to Ximen and wait for me." What he was waiting for was a city full of corpses, a general who fell from his horse, and a traitor who fell from the sky. The master is dead. The general is dead. The entire city was sealed by a golden barrier. A careless man took him out of the pile of corpses. "Would you like to join me, Yunyou Division?" "No, I just want to stay at Shuyunguan." "Then you may have no choice." From then on, a young man who just wanted to grind medicine was forced to embark on a road that ran through nine territories and spanned hundreds of years of grudges. What he has to face is the source crystal that caused the warriors to fall, the ancient gods wiped out by history, and his own heart - replaced by the source crystal.
