As Zhang Tie had eaten too many fruits, he was cultivating at an unprecedented high speed.
To promote to LV 14 from LV 13, it required him to light 144 surging points. This process took Zhang Tie almost 580 days.
If he did not have a trouble-reappearance situation, Zhang Tie even wondered whether he could stand such a tough cultivation in such an isolated space. He might have been driven mad in less than 1 year.
However, during the past 584 days, Zhang Tie learned to sing songs. He always hummed songs alone.
Previously, Zhang Tie didn't know how to sing songs. Nobody taught him either. He could only whistle at most or hum one or two lines. As there were music books in Breaking Heavens Library, Zhang Tie read some and learned to sing songs. He could even identify music scores.
