Please help me find this story, I had it before the list purge incident, but now I can't recalled the title..
Our mc is like noble son of the wealthiest family from the 7 nobles(?)... the kingdom have like 7 nobles alternating to became the king or some sort of it. He is a mage, his attribute is fire but he became earth mage for the sake of money and find more riches, he is also super duper business man mind like and many despise him because he will do anything for profit. One day he is struck by a lighting and remember he is in some kind of novel(?) Or kinda know the future... and so he started to help the novel protag to avoid being killed and also to help get rid of the demon for his own profit(?)... I haven't finished reading it, so I have not much information and some information may be a bit wrong.
