Reincarnated as an Immortal, This Time I Am a Weapon Spirit!

When Sun Yuan was refining the flying sword, the furnace exploded. He died of frustration. When I woke up again, there was a table in front of me. There is a book on the table and a clay figurine in strange clothes. The cover of the book is weird. It shows a blue-haired boy holding a giant ruler, and the phantom of an old man flashes behind him. The title of the book is "The old man in the ring will never meet the genius boy!" The clay figurine was even stranger, and said loudly: "Congratulations to the host for starting the main mission: the evolution of the weapon spirit!"
