Holy Dragon City, City Lord's Hall.
After Tang Zhen returned to loucheng, he gathered all the higher-ups of the Holy Dragon City and discussed the issue of loucheng's promotion.
The current Holy Dragon City already had a strong Army. Tang Zhen simply did not care about the siege of a few fifth-grade foreign clan towers.
From Tang Zhen's point of view, this was merely sending him resources and labor!
As his wealth gradually increased, Tang Zhen no longer cared about the investment of the brain beads. He had the intention to upgrade all the valuable buildings so that they could display their true abilities.
After seeing the strength of the giant tower, Tang Zhen had already faintly realized that the seemingly insignificant attribute increase of the tower and some abilities of the special tower would undergo a qualitative change after being promoted to a certain height.
If used properly, its effect would not be any weaker than an Army of thousands!
