Capítulo 170: Chapter 168-city upgrade, monster siege

When the tower was upgraded to grade two, the city Lord only needed to offer a sacrifice in the tower.

The Holy Dragon city's walls were filled with fully armed soldiers. They looked solemn and expressionless as they looked at the undead army below. Beside them were all kinds of weapons and equipment used to defend the city.

Tang Zhen had already told them that he wanted to advance Lou Cheng. Now that the corpse Army had surrounded the city, the monsters summoned by the rules could only be corpse monsters. They only needed to deal with these corpse monsters that were attacking the city using the previous method.

In the Holy Dragon City, Tang Zhen took out the brain beads from the stone altar and piled them on top of it. At the same time, he began to communicate with the foundation stone to confirm the upgrade of the tower.
