In Eternal Dragon Slayer, the prototype of Ruyang King in history is Chahan timur, who was highly valued by Yuan Di at the end of Yuan Dynasty. He defended the rule of the Yuan Dynasty and made great contributions, but he was not named King Ruyang in the end. At the end of the Yuan Dynasty, wars broke out many times. Chahan Timur led troops to quell the chaos many times and saved the short-lived peace of the Yuan Dynasty, but in the end, like the ending of a TV series, he died because he was betrayed by his own people.

In the TV series, King Ruyang is a loyal minister and a benevolent man. In order to protect world peace, he constantly quelled wars everywhere. Although in others' eyes, he was loyal to the monarch and a good bird, and chose wood, and the Yuan Dynasty was already a spent force, and the people all over the world complained even more, so he should abandon the dark and cast a bright light. But in his view, he is loyal to the monarch, and at the same time he belongs to the Yuan Dynasty. He has the right and responsibility to protect his home.

In history, Chahan Timur was also such a loyal and patriotic person, so although he was alive, the Yuan Dynasty was always in a precarious situation. However, because he is very good at leading troops to fight, he has been trying to suppress all kinds of rebels, so although he is threatening, he has not made great progress. That's why I played his mind, turned against the people around me, and finally let him die in the hands of the most trusted people around me.

Although the positions are different, many people in history still respect him and speak highly of him. Although his life is not as colorful as in TV series, in real life, he is really a loyal soldier, loves his son, but trusts people around him too much. In the end, he didn't die in the battlefield, but in tactics.
