It all started when Liang Teng received an intriguing report from a disciple who had been patrolling the surrounding countryside. The disciple spoke of a young man selling strange contraptions: boxes that kept its contents cold and tubes held in the hand that could project light far into the distance, among other things.
Although such things wouldn't normally be so groundbreaking, what was amazing about these items was that even mortals with no cultivation could use them, and they were being sold at prices even some well-to-do commoners could afford.
Apparently all these contraptions needed to function was to be put out in the sunlight for a few minutes every day. Other than that, they were mostly controlled by simple switches and buttons, and even a child could use these tools with no issue.
