Activate the Portal and I Hand Myself over to the Country!

Jiang Yuan is an ordinary recent college graduate. But on this day, he awakened to an enviable mysterious power - a door that can lead to other worlds! But the problem is... The world behind the door is a terrifying apocalypse. The first time he was full of longing for time travel almost killed him in the mouth of a zombie. The moment before death made Jiang Yuan sober. It is too dangerous for an ordinary person in the apocalyptic world! He needs a thigh. "But in Daxia, isn't the government the thickest thigh?" Behind me is my powerful motherland, who am I afraid of! So Jiang Yuan surrendered, drove to the gate of the military area, and made a decision. He wants to hand himself over to the state! Facing the terrifying zombies again, Jiang Yuan didn't have the slightest fear. Because behind him stood Daxia. The torrent of steel flows, and he is no longer a weak person, but a representative who represents the entire Daxia and communicates with the world. At this moment, he is also the sole commander of the codename "Tinder".
