Since Qin Yan had already cultivated all four Spear Intents to Perfection, controlling them was quite effortless for him.
Under his control, the four Spear Intents gradually stabilized from their violent turmoil. Then, they began advancing toward a common goal.

This caused Qin Yan's face to pale slightly, while his breathing became somewhat hurried.
Each of the four Spear Intents required him to devote a portion of his focus to controlling it.
