Indeed, it was for this reason that Zhang Yanhang had given up the fantasy of using Buddha Relics to upgrade the Four Great Emptiness Purifying World Fist from the very beginning. Instead, he turned to the more pragmatic second upgrade condition, which was to consume equipment of the same quality to enhance the quality of the Four Great Emptiness Purifying World Fist.
Speaking of the quality of the Four Great Emptiness Purifying World Fist, Zhang Yanhang suddenly remembered that it seemed he hadn't upgraded it for a while, as he had been maintaining it at a light Golden quality recently.
But there was no helping it. After all, to continue enhancing the quality of the Four Great Emptiness Purifying World Fist required consuming three light Golden quality weapons. However, he had only managed to collect one light Golden quality Heavenly Martial Soul-devouring Sword and still needed two more weapons of the same quality to improve the Fist's quality.
