"Boom——"
Ten days later, Lin Yun broke through to the peak realm of Huajin.
After Lin Yun grew accustomed to his newfound power, he once again secluded himself for cultivation.
Whoosh——whoosh——whoosh——
The sounds of punches and kicks slicing through the air echoed in Lin Yun's cultivation chamber.
The primary objective was to drastically level up a multitude of martial arts techniques, and Lin Yun, generously, made extensive use of the spirit crystals.
In reality, each time the Cosmic Trading System was used to enhance martial arts techniques, it also carried with it some energy. This energy could also increase Lin Yun's true Qi, and these incremental upgrades, when added together, made quite an impact.
Twenty days after again secluding himself, he had managed to raise all the third-level martial arts techniques—totalling one hundred thirty-six—that he had learned to their respective peak realms.
