My basement connects to another world.

Jiang Yuan stumbled upon a strange game forum. The users were earnestly discussing a groundbreaking, 100% realistic game. Jiang Yuan watched it for fun, until he realized he had actually entered the "game world"! "Wait, others log in with their consciousness, why am I physically transported here?" Since it's a real-life version, then the extraordinary powers and items from that other world… can't they all be brought back to reality?! Thus, his predictable life changed. At first, he developed stealthily, afraid of being exposed. Gradually, he started bringing in otherworldly specialties, adding a little spice to his mundane reality. Later, he was shocked to discover—he was the only one with extraordinary powers in reality? Sorry, I don't eat beef! …Finally, one day, the game went into global open beta. Players who had left the starting area were overjoyed to discover that their powers could be synchronized with reality! Just as they were preparing to run rampant in both worlds, they were devastated to discover that the head of a global behemoth in reality was actually the supreme deity in the game! Looking down at the ambitious "Fourth Calamity," Jiang Yuan smiled gently: "It seems you're all having a lot of fun with the new version."
