[Impersonation + Killing enemies at the border + No system + Prince of the country + Decisive killing + Machiavellian tactics] Ye Chen, the king of special forces, once traveled through time and became the stand-in for the prince's son. The prince died mysteriously, and the prince's wife asked Ye Chen to pretend to be her and go to the border! Ye Chen was happy: "Madam, I always like to help others, especially... Wives." No one thought that this would be the rise of a killing god. Improve the military formation! Surprise attack on enemy camp! Kill the enemy king in formation! Recovering lost ground… Ye Chen fought his way from a thousand households to a king with a different surname. He had hundreds of thousands of border troops under his command. He only knew about Ye Shuai but not about the imperial court. His great achievements shocked the Lord, and Long Yan was furious. Reduce military power! Find out the position! The edicts granting death come one after another! In desperate situation, Ye Chen drew his sword and headed north, shocking the three armies. "Since Your Majesty can't tolerate me, I will take charge of this country by myself!"
