Lin Mo, an outer disciple, discovered a broken book of martial arts that no one cared about in the corner of the sect's library. On the first night of practice, he was surprised to find that every time he circulated for a week, the true energy in his body could be directly converted into copper coins in the real world, which jingled and fell on the bedside. While others were still fighting for a few low-grade spiritual stones, Lin Mo had already saved a small bag of copper coins through "cash withdrawals." Until one day, he tried to activate the second level of the technique - a piece of warm broken silver rolled into the palm of his hand.
