Dr. Dalton Wyatt, a well-known scientist and inventor, was reincarnated into the body of a high school student named Dalton Wyatt. Due to his unfortunate circumstances and complicated life, Dalton Wyatt chose to commit suicide. The new world is completely different from Earth, but there are similarities. Unlike the peaceful Earth, humans fight monsters in this new world and struggle for human survival. Mortals are not enough to fight these mythical and legendary creatures. Some blessed humans can actively control their souls, manifest soul power, and become card apprentices to fight for humanity's chance of survival. Card Apprentices are people who contract with the Grimoire and use a variety of powerful and useful cards to fight monsters and conquer dungeons. The Grimoire gives Card Apprentices the ability to create cards and merge cards, and most importantly, it allows Card Apprentices to express their full potential in Card Showdowns. Although this world has scientific concepts, it is not as focused on electronics and industrialization as on Earth. The world here has cards for every little thing, eliminating the need for electronic equipment. This new world focuses heavily on grimoire abilities, card creation, and card fusion. Coming to a world where money can literally buy power, Dr. Dalton must earn money for his own survival. But luckily, with his information and knowledge from another world, card creation is easier for Dr. Dalton than for other card apprentices. Dr. Dalton creates and sells a variety of perfect, powerful and useful cards to gradually become stronger in order to survive in this world full of monsters.
A very nice book, thumbs up to the author
