Esper Harem in the Apocalypse

Chapter 355 Sneaky Attack

"Hurry up!" the leader yelled at the cashier and pointed his gun at them. "Boss." Two men returned with ten cartons full of money with a pallet separating each layer of one million dollars. "How much is that?" the boss asked. "One pallet has one million, and each carton has 5 pallets. There are ten cartons, so 50 million dollars," a female robber replied. "Only 50 million? This is one of the major banks of this state, and you are telling me there was only 50 million in cash?!" the leader yelled. "There is more We only opened one vault, and there are 9 more vaults," another replied. "Then why are you here?! Get them loaded!" "There are no more cartons available." "Oh!" The leader exclaimed but soon sighed and said, "Then you could have informed me via the walkie-talkie you have been given." The leader hung his gun on the belt around his waist and took out a small tennis ball-sized device from his pocket. ..." Rudy carefully watched as the leader placed the ball on one of the cartons and tapped it three times. The ball opened with a mechanical sound and generated an invisible wave that only Rudy could see. Then, the ball hovered in the air and flashed a bright light that blinded everyone except Rudy. 
The ball and the money from the cartons had disappeared into thin air, and the empty pallets fell on the cartons. "Go now!" He turned to one of the robbers and said, "You, go and check what the other two are doing! Taking out gold was supposed to be easier than taking out the cash!" 
The two robbers left with empty cartons, and the third one rushed to check up on the other two robbers who had gone to steal the gold from the vault.
