Great Guild System of All Realms

Ahem, this is my first time writing and I don't know how to write. Please forgive me if there are any mistakes! ! ! An ordinary high school student in the 21st century, for some reason, traveled to a world where spiritual energy was revived and things in movies, TV, anime, and novels existed. He also activated the Grand Guild System of All Worlds, the Exchange System of All Worlds, and a mutated mobile phone. Let's see how the protagonist travels into another world carrying two systems and a mobile phone. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
