Upgrade to a level 8 building

Following Tang Zhen's return, the entire Holy Dragon City immediately fell into an excited mood.

Tang Zhen's existence had an extremely important meaning to the Holy Dragon City and the original world.

Without Tang Zhen, the Holy Dragon City would be like a dragon without a leader. Even if he had laid a good foundation for the city, there was no guarantee that it would be able to develop as quickly as before after he left!

As for the original world, Tang Zhen was the link that connected the two worlds. Without his existence, the original world's development of the loucheng world would immediately enter a state of stagnation!

More importantly, without a city Lord, many of the functions of the tower would be unusable. It would be like a ship without many helmsmen, stuck in a dilemma in the wind and waves, and there was even the danger of capsizing at any time!
