I Love This Warring States Period

If the sky is sentimental, the sky will also grow old, and the great road will be ruthless and fair. Every existence has the opportunity to aspire to the top, it depends on how to grasp it and how to compete! In this world, no one is born to be a supporting role all his life. No one either. Will be the eternal protagonist. All things compete with each other and the fittest survive. It is precisely because of the competition between the world's heroes, the collision of strengths, and the competition for card advantage. It makes history seem so rich and wonderful, and the world so rich and graceful. Because of a car accident, Ye Xuan accidentally traveled to a highly martial version of the Warring States Period. What accident will he encounter?
