Yu Changxuan could not let go of Yu Mingxuan's death for many years.The elder brother has always been outstanding in the family. He has been competing with his elder brother since he was a child. He wants to be recognized by his father, but he also feels that he is not equally loved.When investigating the old Battle of Black Rock Beach, he found that the battle records were inconsistent with his personal memories: the report stated that the bridge was destroyed by rain, but the people clearly still walked across the bridge when they evacuated.

Adjutant Jiang Chongyi initially admitted that he had changed the report, but attributed the reason to Yu Mingxuan's deployment error.Yu Changxuan didn't want to believe it, so Ye Pingjun continued to sort out the files and found out that he had led people to blow up the enemy's arsenal without permission. Only then did he realize that what Jiang Chongyi really wanted to hide was the choice his brother made to save his younger brother.

Jiang Chongyi finally said that in order to rescue Yu Changxuan who attacked without authorization, Yu Mingxuan temporarily changed his deployment and confronted the enemy head-on. He also asked his adjutant to cover up the reason by saying that the bridge was destroyed, not wanting his brother to bear the responsibility for his first battlefield.Later, the two brothers were trapped by the collapsed heavy objects. The father saw Yu Mingxuan first and ordered to be moved.Yu Changxuan thought he had been abandoned. In fact, Yu Zhongquan tried his best to rescue him after discovering him, but was forcibly taken away by soldiers.

Yu Mingxuan, who was rescued, woke up but could not see his brother, so he insisted on returning and eventually died.After hearing this, Yu Changxuan finally understood that his brother had never regarded him as a rival to win or lose, but had always trusted his abilities.He went to his brother's memorial tablet and cried, blaming himself and it was himself who should be punished.

Jin Zhongfang also brought his brother's letters and ideals during his lifetime, and told him that what Yu Mingxuan hoped for was that his brother could continue on.Ye Pingjun stayed outside the door to accompany him and did not urge him to forget.After Yu Changxuan rearranged his military uniform and worshiped with his father, he gradually no longer regarded life as just comparing with his brother, but instead took over the unfinished business.
