Finding a manga PLEASE HELP!!!!

Has anyone read a manga about a dude reincarnating into a young kid and when he cultivates or something, he explodes a house and he is considered a genius. Then later on he goes on to travel with his parent’s friends. But they were attacked and to save his pregnant mother, he got injured instead. He was saved by a dragon called Sylvia or Sylvie and he trains with her, but she dies. Then he meets a young elf princess and he trains in the elf kingdom with an old grandpa. And they contact his parents who finally find out that he isn’t dead. And after a few years, he meets up with them again and they find out how strong he is and he has multiple strengths. And after a few months, he goes on adventures with one of the girls he traveled with previously. Then he goes attend a academy.
