Chen Mo looked at the four glowing halos and almost laughed. Maybe this kind of defensive rune was special after all!
Perhaps these halos had been designed with cave use in mind. Not only could they protect the user, but they could also illuminate the surroundings and make it easier to see the environment.
And perhaps they could even be used to determine the positions of teammates through the halos!
Chen Mo muttered things he did not even believe himself as he stared at the light displayed by the runes before him, wanting to see whether this kind of rune's defense might surpass the Vajra Talismans he had made in other aspects.
If it was more advanced than the ones he made, then he should find a way to get one as a reference for study. It might even improve his talisman-making skills.
Besides, this glowing form of defense was quite interesting. There were no glowing Vajra Talismans in the Cultivation World. If he could make this kind of glowing talisman, it might come in handy under certain special circumstances.
