The Thousand Thread Technique could probably be considered the Alchemy Master Alliance's cornerstone cultivation technique.
This was a cultivation technique created by an alchemist. After cultivating it, it would not have any effect on one's inner strength. In other words, cultivating the Thousand Thread Technique would not increase one's martial realm.
However, if he succeeded in cultivating the Thousand Thread Technique, it would be of great help to his alchemy skills.
Actually, it wasn't just alchemy. From what Chen Fei understood, the Thousand Thread Technique cultivated the heart and mind power of a person.
It would allow his control over his mind to become extremely precise so that not only was he like a fish in water when it came to pill concoction, it would also be like adding wings to a tiger when it came to martial arts.
