What was the difference between true qi and true essence in novels?

The true qi and true essence in the novel were fictional cosmic forces that had nothing to do with the real world. True Qi was a mysterious energy that was regarded as the essence of ancient Chinese Taoist cultivation. It had powerful strength and mysterious characteristics. In the novel, zhenqi was described as a power that could control time and space. It could be used to cast various spells and skills with extraordinary power. True essence was a more common universal power, usually described as a kind of energy that could be obtained through cultivation and absorbing the spiritual energy of heaven and earth. It could also be released and controlled through some special means. True essence was used in novels to cast various spells and skills with greater power and longer duration effects. It was important to note that the true qi and true essence in the novel were fictional and had nothing to do with the real world. They are usually fictional powers created by the author's imagination and literary techniques, with exaggerated effects and storytelling.
