Subject to perspective
In the first life, Chen Cheng felt that the death of Prime Minister Zuo was unjust, and the death of all his family members was even more unjust. He just protected a child by the way. Why did you pay for three lifetimes? The child became young, sickly, and almost wanted to die, but he was forced to promise to marry the general's daughter. As soon as he promised Xie Yunjun, he really left with peace of mind, leaving him alone to support Jingguo's prosperity and peace, and with the queen who he had always regarded as his sister, it lasted less than ten years.
In the second life, Chen Cheng still saved the child. As soon as the child had a fever, he replaced Xie Yunjun in the previous life. This time, the rebellion was going smoothly. In a few years, they opened up new territories to fight against the barbarians. Xie Yunjun fell ill again and was about to die as in the last life. He was so sick that he was worried that the barbarians would come back and force Chen Cheng to kill 200,000 prisoners of war before he died.
In the third life, Xie Yunjun came to Chen Cheng to rebel early, but Chen Cheng felt really tired. Xie Yunjun has been an ancient scholar for three lifetimes. How could he do all the hard work he could do in his second lifetime? This time he is really tired.
