Push Forward in Smoke!

To prevent monsters attacking their city, Dragon City used a lot of structures and technology to build forts and strongholds as the initial structure. 

Even skyscrapers that were hundreds of meters tall were in the shape of pyramids and gravity dams. Their bases were huge, and the higher they went up, the more they would shrink in width. The additional space would be perfect to serve as the base for anti-aircraft guns to fend against flying monsters. 

Hence, the crystal bombs the monsters buried underground were unable to reduce the dozens of buildings into dust right away. 

Even though they swayed and started tilting toward the ground while parts of them collapsed, the overall structure of those buildings still remained intact. 

The citizens inside were fine for the time being, unless they were affected by the impact of the explosions underground. 

But the explosions did not stop. 

Each time one happened, the ground would tremble fiercely.
