Diqiuren Shizai Tai Xiongmeng Le

Fifty years ago, he transmigrated into Dragon City, a lone fierce fighter who raised Earth's banner to fight against the tide of fearsome alien monsters. Fifty years later, Meng Chao was reverted back to the time before the invasion, reborn with a system that made him stronger with every contribution he made. In this life, he will smash the monsters, stomp the demons, and tear down the old gods. In this life, he swore he will rewrite his own, his family's, and even the entire humanity's final fate!
