Gu Chen sat cross-legged on the bed, the Gangqi within his body moving along the pathway of the Great Sun True Skill. It was growing increasingly fiercer and hotter.
After all, the Great Sun True Skill was a Superior Martial Skill. Its purity of Gangqi far surpassed the Pure Yang Wuji Gong, and its power was even more formidable.
If Gu Chen could cultivate the unique Gangqi of the Great Sun, by the time his cultivation was profound, he would truly possess the power to burn mountains and boil seas.
As for how to cultivate the Great Sun Gangqi, the secret text only recorded that one needed to have extremely deep cultivation, then condense all the Gangqi into a single point, transform it into a "spark", and ignite it with a special method to have a sliver of chance in achieving the Great Sun Gangqi.
Naturally, there was a simpler method to transform the Gangqi in the body into Great Sun Gangqi, which was through the Sun Flame Stone.
