Another World Collides with Advanced Civilization

[Western fantasy + technology + magic + different world + fantasy + time travel + invincible flow + crushing + world view] I used to believe in magic VS I used to believe in technology Guan Fengfan, a scientific wizard, his country is a high civilization in the universe. However, due to an unexpected experiment, Guan Fengfan and his starship traveled together to a multiverse where magic existed. "Science is a joke? Can it be eaten? I don't understand! Magic is much easier to use!" "Stinky aliens are coming to beg for food!" The local natives from another world mocked Guan Fengfan. Indeed, this seemingly medieval society actually contains magic, and even local indigenous people can make "nuclear bombs" with their bare hands. "While you're still in Magic, your top priority is to go under the apple tree and understand the force of gravity!" As a scientific genius and possessor of countless black technologies, Guan Fengfan, it is time for these natives from another world to see what they are like as the God of Technology. At the same time, Guan Fengfan also found that he came to this magical universe and awakened the ability to use magic. At this time, a clan of demons using dark magic suddenly appeared. They said to the natives of the other world: "What age is it, and you are still doing traditional magic?!" "Dark magic! Coming to your door soon!" In short, the originally peaceful world began to become lively, and it also attracted the attention of the ultimate creator outside the universe...
