Tower Defense Survival: I Defend the Whole Country Alone!

As the man in front of him was attacked by the undead that filled the sky, tragic roars sounded. Pierce received a message from the Tower Defense world.

[All participants in this instance dungeon have died, leaving only one special participant. Therefore, this instance dungeon's quest is over. Please take your relevant rewards…]

When he saw this message, Pierce suddenly realized that he had become a special contestant in the eyes of Tower Defense World.

Was he already considered different from other contestants?

Pierce took the bottle of bloodline and waited for the portal to appear.

All the participants were dead. Thus, the instance dungeon ended.

He had obtained the rewards, but unfortunately, he did not see the contestants fighting the undead.

A dark green portal appeared before Pierce's group.

The dark green portal was very familiar to them. Wasn't this the gate that had appeared when they opened the entrance to this world?
