Brothers Who Are Not Related by Blood

There is no system, but you are born rich. No golden fingers, but extremely talented. There is no time travel, but it is a different world. There is no cultivation, but one can seize the body. There are no brave men, but they have to fight against monsters. There is no heroine and no harem. Not a cool article, not a cool article, not a cool article. I write whatever I want, and you can read whatever I want. In the magical world, two noble sons were killed by the ignorant protagonist in an accident. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
