Michael was suddenly reborn into a another world by a God because of an accidental death. To make up for this fact, the God gave him another life in a fantasy world of swords, magic, and monsters.

Unfortunately, it turned out that the world he was reborn into was still stuck in the medieval times. It didn't have electricity, it didn't have proper plumbing, and it didn't have any technology that he was so used to back in his old world.

But thanks to the God's blessing and an AI assistant called ChatJK1, he was given the power to MAKE his life comfortable. Slowly, Michael transforms this new world into a place even better than his previous one by taking ideas from the modern world and putting it in this world, with the added bonus of magic.

Reborn as the Genius Son of the Richest Family

As the Apex Jaguar crashed onto the stone brick walls, Michael felt the crystallized Earth mana in the area destabilize for a second.

This is a chance, ChatJK3!

The defensive measures set by the person who created this tomb was disabled for a split second. The chamber shimmered imperceptibly for normal people who didn't have an insane mana sensitivity. But for Michael, it was enough for him to peek through the curtain and partially see the mechanism hidden inside.

This was definitely enough time for his personal AI assistant to rush its analysis.

[Understood. Analyzing the mana composition of the tomb…]
