You call this a defensive lord?

The cosmic-level game Conquest Online has been grandly launched, and tens of billions of people around the world have been drawn into it, becoming lords and fighting for survival.
Thousands of balls on the same map, tens of thousands of races on the same server, the excitement is at its maximum.

When he first entered the game world, Mo Yu looked at the forest troll knocking on the door for happiness outside the territory and his eyes were filled with tears.

At this time, Mo Yu's rich LOL experience of practicing under the tower for two and a half years allowed him to successfully awaken his exclusive talent, Son of the Tower, where everything can be a tower...
Several years later, when others were trembling under the invasion of monsters and alien forces, Mo Yu scratched his head and wondered, where is the monster in my house?
Enemy: Your defense tower is right in my face!
Mo Yu: Oh, that’s okay!
