But there is always someone stronger.
The three-foot defensive space was not indestructible. Even Guo Wei couldn't guarantee that he could block every single attack.
Chu Lingguang hoped that the Spear Intent Fluctuation would become another layer of defense for this three-foot space. Not only could it catch an enemy off guard at a critical moment, but it could also form a formidable defense in a pinch.
For example, when he had casually pointed his Long Spear, the resulting Spear Intent Fluctuation had caught a falling pine tree. The fluctuation had ultimately torn the tree to shreds instead of locking it in place for long, but no matter. As long as the Spear Intent could block all incoming attacks, it could serve both offensive and defensive purposes.
However, Chu Lingguang was a perfectionist.
