40th wave,
The tower was looking magnificent, with its height reaching new feats. The defensive wall was clean from the tower's side.
There was furniture in William's room and the upgrades on the bed had made it bigger and better. The sheets now had the ability to auto-clean. It was expensive yet William needed it desperately. All the blood, sweat, and dirt had made the sheets unsleepable.
Yet the main beauty of the tower was not inside the defensive walls but outside. There were shining elements at every corner of the ground.
Some had layers of ice on them while some had fire, it was a magnificent display. The tower could now be called a traditional one.
It had all the different barricades at their peak levels to defend against the waves.
A few of the precious waves had become a joke now, William had not seen even a single creature inside the defensive walls since a few waves.
