This forbidden technique was called Force.
He first understood Force from Lu Yue.
Lu Yue cultivated the Sword Force.
At that time, he was curious about Lu Yue's ability. After Lin Ran's explanation, he understood Force and specially checked the relevant information.
However, there were very few descriptions of Force on the Internet, and he did not have the authority to check the cultivation method.
He also learned from the Internet that Force was an extremely special cultivation method.
Sword Force, Aura Force, Saber Force… All kinds of attack methods could be condensed into Force. This was a kind of integration with the weapon's essence, Qi, and spirit.
Moreover, this ability had a distinctive trait: it had nothing to do with the quality and quantity of Spiritual Qi in his body.
The strength of Force was related to one's comprehension of Force.
Feng Qi was interested in this cultivation method.
