Every twenty years, the world of Tower Defense arrives to take away people and make them participate in the survival game. You can get unimaginable rewards if you can win. You can also inflict severe damage to your country if you lose.
Pierce finds himself in this world, and sent to the Tower Defense alone, while other teams have a hundred people. 
Fortunately, he awakens golden hint system. Not only can he see useful alerts, he can also discover the fatal weaknesses of his enemies. Every monster he takes down rewards him with top-tier prizes. While the other players are still struggling, he is already swinging his swords to take the lives of gods.

[Detected that the world is operating normally. In order to further improve the participants' experience, the Blood Moon mode has been activated!]

[This mode will be challenged in dungeon mode!]

[The rules of this Blood Moon dungeon will now be announced!]

Since when did the Tower Defense world have dungeons?

Before Pierce could think further, a series of messages appeared before him.

[Blood Moon dungeon is the first Tower Defense dungeon challenge. The winner will receive rich rewards!]

[The dungeon is a special space created in order to increase the strength of the participants in the Tower Defense world.]

[Any casualties in this dungeon will be healed up after the instance dungeon ends. In other words, death in this dungeon does not represent the final death!]

[Each country can at most select three contestants to enter the instance dungeon!]
