Two Realms Pass

In 2070 AD, human science and technology was highly developed. Mechas, space carriers, rail guns, drone swarms and nuclear fusion energy formed the sharpest steel fangs of the earth's civilization. However, a super-large particle collision experiment in Geneva, Switzerland, opened a bloody door to another world. On the other side of the wormhole is a demonic world where there is no day or night and the sky is always scarlet. An army of demons nearly three meters tall, with double horns and tough skin poured out from behind the door. The magician controls the five elements of magic, the beastmaster controls the monsters and dragons, and the berserker is physically powerful and can overturn a tank with his bare hands. Geneva fell and Europe collapsed. At first, humans thought it was just an experimental accident that went out of control. It wasn't until the communication tower was destroyed, the airport was captured, the city was massacred, and the survivors were driven to the front by the demons to act as human shields, that the whole world finally understood—— This is not a disaster. This is war.
