Cultivation is about refining oneself and one's heart.The heavens and earth are the furnace, creation is the work, yin and yang are the carbon, the myriad paths are the copper, and with a steadfast Dao heart, one can refine a Primordial Dao Fruit.Refining pills, refining tools, refining formations, refining talismans, refining swords, refining souls, refining medicine, refining plagues, refining demons, refining devils, refining the heart, refining worlds, refining the Dao...Everything in nature can be refined!This is what Xuan Qing says.If you provoke him, he will even refine the Heavenly Dao to show you!Of course, this all began the day he joined the Jie sect...

Chen Sha came to a world of immortal martial arts and was ordered to take charge of the world’s first sect.

Before his death, the previous chief told him:

“If you don’t become the best in the world for one day, you are not allowed to go down the mountain for one day.”

So he closed himself in painstakingly, crossed the heaven gate in his body, and faced off against the ancient and modern powerhouses…

…

Many years later, Chen Sha recalled the day he went down the mountain,

From the moment he descended the mountain, he was number one in the world.

In the next ten epochs, any gods and demons have returned, immortals and Buddhas have lived in the world, ancient powers and ancient gods have appeared one after another.

No matter how the times change, he has always been No. 1 in the world and has never changed.
