It was not a Martial Arts Practice Card!
A misjudgment.
The card he extracted from the barbarian's corpse was not a Martial Arts Practice Card.
Instead——
Invisibility Card!
Eh…
After reading the description, Su Jingxing was stunned for a moment.
It seems that the Invisibility Card is not inferior to the Martial Arts Practice Card?
As the name suggested, the Invisibility Card could turn Su Jingxing's entire body invisible, including his clothes.
Duration, 15 minutes!
If this ability was used well, it really would not lose out to the Martial Arts Card.
Of course, both cards had their own distinguishing traits.
It could only be said that extracting the Invisibility Card was not a loss. He was not disappointed.
Su Jingxing smacked his lips and happily put the card away.
Then, he took out the card from the corpse of Black Tiger Gang's protector and read the description.
