When Heaven is about to entrust a person with a great responsibility, he must first strain his mind and will, strain his muscles and bones, starve his body and skin, deplete his body, and mess up his actions, so tempting his mind and forbearance will benefit him beyond his ability. People always make mistakes, and then they can change; they are stuck in the heart, weighed by worries, and then act; they are marked by color, produced by sound, and then metaphor. The so-called peerless one here means that even if the opponent now has the strongest strength in the world, in the end it is just a narrow encounter and the brave will win. In a desperate situation, the stronger the enemy is, the stronger I will be. This is the unique fighting emperor.
