OP Skills in Another World

After dying too young from a chronic illness, Crave is reincarnated in a dark-ages world with the power to create anything he chooses. Guided by a snarky 5,000-year-old dragon emperor trapped in his mind, he joins adventurers Biro, Amane, Misa, and Jasmine against the mysterious Fold, who seek to destroy Valdris. Their first battle begins when Crave wakes in a field surrounded by 1,000 porcine orcs and summons advanced technology no one in this world has ever seen.
