Just find the time , space , reality and power infinity stones use the stones to train his divinity like using time and space stone to create time training room(like the dragon ball one) so he spend to train in room for million years while only one day pass in outside , or even use reality stone to gain knowledge on how to use reality power so than can use reality power without the help of stone and use power stone to forcefully to increase his divinity power capacity and increasing his sun god powers more Powerful permanent , little by little as if directly increase his powers it my cause harm or death , or become powerful enough to kill surtur and take away his sword(The twilight sword) which is powerful as Odin's Gungir. Or use sum god powers to increase his powers in physical body strength like a kryptonite who they permanently increase their physical body strength by absorbing sun radiation. By using this method our MC will be strong as that Atlas who is physical strength put Cronus , zeus and brother in fear of his physical strength and atlas is also strongest cause he is the only one to present day of marvel is still holding earth , sky. (Zeus punishment cause he knew having monster like atlas is hard to kill with his absurb body strength)
The reason I dislike stories like this is the MC gets too strong too fast which makes rth story a bore. I doesn't matter if you like Hera or not she is the queen of the Gods with hundreds of years more experience than him and she should thrash him like the child he is. I don't know why authors hold the delusion that reincarnating In a world makes you smarter than everyone else and all of a sudden one can do new things with your powers because everyone else are idiots. right now he is a teen and is apparently more powerful ful than the queen of Olympus at less than 20 chapters, by chapter 50 he'll probably already be stronger than Zeus and the elder gods so what's the point of reading the story.
