"Divine guidance!" Park Sanyi Number Two praised, a smile appearing on his face. He was actually quite proud of this operation.
He made a show of adjusting his clothes. "Let's go to the exit of the emergency passage. A skyscraper with over three hundred floors has many people. Pick out those we need and take them all away."
"Rest assured, Angel Envoy, we have committed the appearances of those people to heart," one of the followers said.
They swiftly reached the exit, where the followers took out several sealed gas canisters and released some sort of colorless and odorless gas outside.
Park Sanyi Number One had secretly loosened the valve somewhat and would check it daily to prevent anyone from discovering and "repairing" it.
In the eyes of Park Sanyi Number Two, the cunning of the plan was like using a small force to move a great weight. Who would have thought that the real key lay in a tiny valve within a skyscraper over three hundred floors high?
