First of all, we all know that those four people are Han Chinese, which is true. However, these four people were adopted by Mu Rongfu when they were young. It can be said that Mu Rongfu single-handedly raised them. In other words, if Mu Rongfu doesn't adopt the four of them, maybe all four of them will die.

As the saying goes, a drop of water is rewarded as a spring, not to mention saving people, and it has been raised for so many years. Therefore, these four fools have regarded Mu Rongfu as their second-generation parents, and Mu Rongfu is in charge. Rightly or wrongly, all four of them fully believe what Mu Rongfu said.

So, although all four of them are Han Chinese, they are not the same nation as Mu Rongfu. But in the eyes of the four of them, the only thing they can do is to help Mu Rongfu accomplish what he wants, and that is to work for him. Other things about what nationality, at sixes and sevens, they did not think of, thinking that they would not betray Mu Rongfu because of these things.

Although the four of them gradually realized that what they had done might be wrong, there was no way to open the bow without looking back. Since they chose to repay Mu Rongfu, even if Mu Rongfu said something wrong or something wrong, the four of them could not bring it up or help Mu Rongfu to correct it. So the four of them must help Mu Rongfu invade the Central Plains and revive Yan.

The four of them were adopted by the Murong family when they were very young, so they wanted to repay Murong Jia's kindness to their upbringing, so Murong Jia has always been loyal to Mu Rongfu. People under the eaves have to bow their heads. And not all Han people help Han people, but Han people cheat Han people, right?
