Weaponsmithing and alchemy.
These were knowledge and techniques that transcended far beyond the era these cultivators were in. Most of what they knew was limited to the art of refining qi.
Hence, when Feng Gu noticed the medicinal pills and Dao weapons, he was so shocked, and it challenged his perception of this world.
On this day, Chu Kuangren, the inventor of these revolutionary items, was standing right in front of him.
More shockingly, Chu Kuangren seemed to be unfazed by his own inventions. It made Feng Gu question if he was somehow over-reacting.
Feng Gu could not help but lament the situation.
Chu Kuangren was such an unordinary individual. Not only did his lectures on the Dao invoke an astonishing display of Daoist Transformations, but Chu Kuangren was also the inventor of two unique items. These were groundbreaking feats for humans of that era.
Were those the typical doings of a saint?
