Marquis Yan was the empress's older brother, and the Ancestors of the Yan family were three generations of emperors, and they were famous. Marquis Yan was even more extraordinary, and when he was young, he was talented and outstanding. When he was twenty years old, he dared to break into the enemy's military camp alone, and face thousands of enemy troops alone, his face did not change color, and he even fought with one word, so that the enemy finally retreated. When Marquis Yan was young, he was deeply in love with Lin Xie's sister Lin Yue, who was the future Concubine Chen. Ke Lin Yueyao was directly snatched away by Emperor Xiaoxuan of Liang, who ascended the throne, and was included in the palace wall. But in this way, Marquis Yan still loved Concubine Chen, and after Princess Chen's death, he was almost crazy and wanted to avenge Concubine Chen.

First, Marquis Yan was decadent
Thirteen years ago, Concubine Chen, grief-stricken by King Qi's affair, hanged herself. Marquis Yan was disheartened because of Concubine Chen's death, so he sought out immortals and visited the Tao, no longer paying attention to mundane affairs, and walking between mountains and rivers all day. Maybe he didn't want to think about Concubine Chen's death, wanted to shift his attention to the other side, and didn't want to let himself continue to hurt.
But Concubine Chen's death had been pressing on him after all, and he seemed to have nothing to do but be depressed. Even Jinling City rarely returned, and his own son only gave enough silver to the queen, so he ignored it. A Marquis Yan, who was once brilliant, went on to decadence.
Second, love is crazy
Marquis Yan's love for Concubine Chen had already penetrated deep into the marrow. When he was young and walked the rivers and lakes with Lin Xie, he changed his name to Yao Yiyan. Changing the name of the person she loved to her own surname seemed to want to be able to call out her name every day, just as her concubine could be by his side every day.
After Concubine Chen was incorporated into the palace by Emperor Liang, Marquis Yan had no choice but to marry another wife. He gave birth to a son, later Yan Yujin. It can be said that Marquis Yan was still deeply in love with Concubine Chen at this time, even though she had already left him. Concubine Chen gave birth to a son, named Xiao Jingyu. You can take a closer look, you can find that Yujin is the reverse of Jing Yu's name, which shows that Marquis Yan has a deep affection.
Third, love is crazy
The destruction of the Red Flame Army and the death of Concubine Chen completely aroused the devil in Marquis Yan's heart. He hated, hated Emperor Liang for treachery, forgot his promises, and did not give the great liang he had promised. Emperor Hate Liang disregarded his past feelings and directly raised a butcher knife to his former brother. Emperor Hate Liang stole his Yue Yao, but he did not cherish it well, causing Yue Yao to hang himself.
So he wanted revenge, wanted the king of the girder to die. He then loaded gunpowder on the altar and wanted Emperor Liang to detonate the gunpowder during the sacrifice. He did not want to stop Mei Changsu and gave up revenge under the advice of Mei Changsu. But as he said, he thanked Mei Changsu for stopping him, but he never regretted doing it.
Marquis Yan's love for Concubine Chen was like being poisoned, and it had already gone deep into the bone marrow, but Marquis Yan didn't want to get rid of this poison. It was like letting this spread all the way through his heart, all the way. Therefore, after Concubine Chen married Emperor Liang, Hou Yan hid a secret, that is, his name Yujin was actually very close to King Qi's name Jing Yu. It was many years before Yujin understood the past of the elders. To give you a love like this, what do you want?
