"Since this is an ancient cultivation method, the method is simple." Cheng Sheng spoke as he recited some lines to everyone.
Everyone followed what he said and immediately felt the flow of qi in their limbs. "It is really simple." They spoke after they gathered qi from the surroundings and made it pass through their limbs before spreading the qi all over their body.
Although they also gather qi to first establish their body's foundation for cultivation before forming their golden core, they gather qi and place it all on their dantian before they distribute the qi all over their body. This way, they could establish their foundation and also slowly but surely form a golden core in their dantian.
