Accidentally traveled to the world of immortal cultivation, where strength is respected, immortals and demons roam freely, but weapon refiners are extremely rare.
As a high school student with a lot of knowledge in mathematics, physics and chemistry, he used his knowledge of physics to melt unmeltable metals and create impossible weapons. A spiritual universe comparable to the Metaverse has been established, and immortal cultivators have also become addicted to the game and suffered greatly from it.
His method of refining steel at will is also carefully preserved by the big family as a secret method that is not passed down.
The weapons he made were of better quality and cheaper than those of the aborigines. Therefore, he became a weapon refiner, one of the most popular and respected professions in the world.
The reason why he can do this is because the technological development in this world is almost zero. Science can also cultivate immortality, and it can cultivate immortality better and more efficiently...
The start is so awkward and I can't stand it.
