Yan He and Yan Ye are two unrelated people. You treat them as your brother and I treat them as my younger brother. They don't get along well, but they're not that much better.
It just so happened that Yan He was a hard-hearted person and was killed by his brother Yan Ye for profit. Seeing his brother step over his body expressionlessly, he felt resentful in his heart. He thought that if he were reborn, I would fight for your family property and have a relationship with you, and then see how I kill you! Let's see how you kill me then! Let's see if you're still willing to kill me! I am your biological brother and you are willing to kill me!
Thus, our rebirth of Yan He returns to the time when he first met Yan Ye. But because he was soft-hearted, he didn't do anything.
He was always tolerant of Yan Ye. If he couldn't do it, Yan Ye could only do it to him.
