Initially, Jiang Cheng tried to come up with a talisman that could quickly secure an advantage, such as the Muscle Relaxation Talisman.
Using a talisman to control an opponent for a full minute, even a fool could secure victory and win the match within that minute of control.
Then Jiang Cheng discovered that this approach, which worked well in the Qi Cultivation Stage, was hard to pull off during the Foundation Establishment Stage.
The reason being, a cultivator's overall strength on their panel increased, leading to a decline in the efficacy of a single talisman.
Simply put, in a match during the Qi Cultivation Stage, a single move could determine the outcome. For instance, if you have a powerful spell that the opponent can't defend against, they naturally have no choice but to surrender.
