章節 203: 203. Getting the Resources

Anna was at the back, looking at the surrounding walls and floors with a sigh. It was estimated that even if they wanted to clean up the building, it would require a lot of water and resources.

These were all resources that they didn't have.

The project to clean the city and reclaim everything would definitely take an extremely long time.

They soon reached the ninth floor.

"Hahaha! No one has come here before." Nathan was happy when he saw that the door was still locked tightly. He opened it with his fingerprints and the others were staring at the key lock in front of them.

"What?"

"How come this key lock is still functioning? The electricity is cut, right?"

"It's powered with battery. As long as the entire lock is not soaked with water, it'll not malfunction," Nathan said proudly. He felt that he had the vision to set this to use battery instead of the normal electrical sources.
