Huo yuHao was a child of a maid. But the duke doted on her but unfortunately she passed away when he was 5 years old even though he is reincarnated ,she was also a mother for him.
He decided after awakening the spirit will destroy the evil sage tiger clan.
(The issue is that after the duke left for war he wanted to hand over all the power the his wife ( the daughter of the current emperor)
She was quite jealous of the doting she got so after he left she put them on a wooden hut telling that she has disease.
And also they bullied Huo yuhao and when he fought back he got punishment .
He only has one thing in mind that is revenge
