It is still necessary to talk about this strange continent first.

It's a new and old continent.

Before Jack set foot on the territory of Tana, the three great powers in the east - the Vidi Kingdom of Gabo, the Missu Kingdom of Coron, and the Holy Ape Kingdom of El - these three countries were built by humans, of course, before Jack set foot on the frontier of Tana, the continent should be uninhabited and full of dangers for him. It can also be said that the continent is dangerous, because to the west of the snow-capped mountains, the alien legions led by the Gemo led by Montaro, as well as countless small barbarian countries, threaten the security of the human world in the east all the time. Fortunately, Peter's Grand Canyon stretches for 500 kilometers from north to south, and the Victorian Kingdom has been silently assuming the identity of a pioneer and stubbornly resisting the alien legions, and the human world is still developing peacefully.

The war between the aliens and the humans began thousands of years ago, and all this was fermented before Jack arrived. Why? Because there is a mysterious power in the territory of Tana, the spirit of Tana.

This continent, named after a spiritual power, has been slaughtered precisely because of the kind "help" it has brought to the world. Humans think simply, but alien legions think very complicated.

In this season of confrontation between alien humans, another force has quietly spread to the territory of Tana. In the bleak land, the barbarian beast herd led by Lina, the leader of the evil beast clan, is waiting for the best time to attack......

It was so unfortunate that Jack came to this continent from the peaceful world, and all this was completely unknown to him.
