Testing the Energy Shield

"Dear survivor, the remaining charging time for the 'Energy Shield' you set up is seventy-one hours, fifty-eight minutes, and forty-five seconds. You can consume energy to accelerate the charging time."

Without hesitation, Alex asked, "What energy is needed?"

"The fastest energy for charging the 'Energy Shield' is electrical energy. We have detected electrical energy in your shelter. Would you like to connect the charging channel?"

"Connect it!" Alex didn't hesitate.

But he was puzzled.

"How much time can be reduced by accelerating the charging?"

The AI assistant paused slightly, then provided an accurate figure.

"Dear survivor, with the additional charging, the 'Energy Shield' charging time will be reduced to six hours."

Alex frowned slightly, crossing his arms.

Although the charging time had been reduced to six hours, which was quite good, he was still somewhat dissatisfied.
