It's pretty good, but the story is starting to get repetitive with the battle spree going on between him and the enemies(gods). The story are on racism and religion so it pretty irritating to read. MC tends to be OP but somehow the enemies are always stronger than MC because mainly the enemies are gods at this point. There are fuck tons of characters going on I can even barely remember which is who. The harem is growing from all races, his body is still young so there is no snusnu at the moment. But he will take the responsibility once he get older. Also the author like to add unnecessary backstory to a mob that is about to get destroyed. Really wasting my time

.
The good thing is how the MC handles the situation. He kills when he need and revenge is a must(he tried to forgive but he can't, the hatred is too much). The lore going on in that series is great too, it's so damn interesting you keep wanting more of it. His enemy analysis is top notch, he mostly able to see through their ability on the first try. His skill combination and how he uses them are great. He is able to create a Mahou Shoujo transforming staff/wand and a Henshin weapon (Kamen Rider/Power Ranger). He also successfully revived her mother. She is currently more stronger than her past life thanks to the material used when constructing her new body. She have turned into a new species called Chaos Elves and become an incarnation of Vida(gods of new species).
The reason why MC develop a Death Magic with huge mana pool is due to he is a reincarnation of 4 soul fragments of crafting heroes in the past. In the past there is a huge war going on between gods and demon king. God use reincarnation hero to fight the Demon king, but failed. Demon king break the souls of the crafting heroes preventing them from going back to the wheel of reincarnation. Rodcorte (god of reincarnation) combines 4 fragments of the broken soul and send it back to the wheel of reincarnation. He doesn't have any memories/skill of the past heroes.
