The books here had the basics of all martial arts and the origins. What caught Yeowun’s eye was the book called ‘Origin of Internal Energy’.

‘Nano, scan the book.’

Yeowun then began skimming through the book and realized that the information it contained seemed useful. It was a book that explained the basis of internal energy that might help Nano analyze and help with the breathing skill. Yeowun then used all his remaining time to scan the books on the shelf. He didn’t realize it now, but this would later help him in creating his own martial arts.
