My World's Journey to All Realms

The protagonist is a student at school, but one trip completely changed his life. The protagonist and his classmates climbed to an undeveloped mountain range. The weather suddenly turned into heavy rain, and unfortunately they fell off a cliff. Fortunately, there was a spring at the bottom of the cliff. The protagonist was rescued and obtained the Minecraft system. When the system was turned on, the surroundings were full of blocks. All items could be synthesized, and there was a chance to obtain modules by digging. This novel and its characters are purely fictitious.
