A Milestone! Back to the Electric Age

"Good lord, the byproduct of system optimization is sick, don't you think? Humans will have great progress in technology if this can be reverse-engineered to find out ways to optimize the battery and the motor." 

As Su Mo put the crossbow on the table, he stared curiously at the upgraded electrical crossbow. 

There was no ideal solution for the battery problem before everyone passed through the wasteland. 

Major factories were frantically installing electrical cores in batteries and thinking of ways to shorten the time the batteries needed to charge. 

However, the amount of charge a battery could hold was proportional to its size and weight. The bigger the amount of charge, the larger its size and the heavier it weighed. No one was making a conscious effort in developing smaller batteries that could hold larger amounts of charge.
