The sword injury on Manjusri's body has disappeared, and from the outside, it looks as though he has completely healed.
As for the internal injuries, Jiang Li, even with the Heavenly Eye, could not investigate without alerting Manjusri, so he did not use it.
Even so, it was enough to astonish Jiang Li.
The Slaying Immortal Sword refined by Daoist Guang Cheng is not the original, but to call it a counterfeit would be unjust.
He merged it with his own Yin Yang Two Extremes Sword, attempting to recreate the Slaying Immortal Sword, and he indeed succeeded. Although the sword's level does not match the original, it has the foundation, at most it can be considered a low-tier version of the Slaying Immortal Sword, far from being a counterfeit.
