The fluctuations Chu Lingguang released from his flesh and blood had led Zhuoyi and Poisonous Snake to mistake it for Spear Intent. It wasn't until Yun Hong appeared that it was confirmed not to be Spear Intent.
The basis for this judgment was that the fluctuation originated from his flesh and blood, not his Sea of Consciousness.
At that time, Chu Lingguang and many others realized that the key to forming Spear Intent was releasing energy fluctuations from the Sea of Consciousness. So, once he grasped Spiritual Sense and could emit Spiritual Sense Fluctuations, he tried to combine them with his Spear Technique.
But he had never succeeded.
Only now did he realize that the true key to forming Spear Intent was not just releasing power from the Sea of Consciousness. It was also using that power to enhance his Flesh and Blood Divine Abilities and create a resonance with his Long Spear.
