"How do you recharge the backup energy bar? Oh, automatic charging, pretty cool!"
Zhang Su observed carefully and found the empty second energy slot had a faint blue gleam flickering, as if capturing energy particles from the void. The progress bar on the far left also showed a thin layer that had possibly recovered... a ten-thousandth?
Specific recovery speed and whether there are other methods to speed it up require further verification. As long as it can slowly recover, it's good.
"Let's test if it can actually enhance!"
Zhang Su decided to experiment while his own energy slot was full, and simply activated the second backup energy slot.
Repeating the previous operation, everything sped up in his mind, but when the energy slots fused again, he didn't feel his body getting stronger. He just felt warm, like a small furnace emitting heat.
"Well... I thought too much."
Zhang Su licked his lips, touching the ice-cold tank steering wheel, fantasizing about becoming One Punch Man.
