435 A Complete Victory!

[Do you want to spend 100 Technology Points to exchange for an energy station?]

"Yes!"

Zhao Yu still had 400 Technology Points left. He planned to see what new buildings would be refreshed after the completion of the energy station.

Zhao Yu finally saw the list of three new buildings.

"The Combat Research Institute, Defense Works, and Air Force Command Center..."

"It seems to temporarily have no effect on the battle situation..."

Zhao Yu carefully examined it. The defense works could create walls, fortresses, watch towers, and other facilities.

The Air Force Commander Center could coordinate and deploy air strike, but with the current restrictions of Sky City, he dared not use it casually.

The Combat Research Institute refreshed the entire list of buildings' weapons and equipment with new content.

"Invisible tanks, prism tanks..."

Zhao Yu scratched his head, seeming to find them of little use.
