On the back of the Celestial Spirit Sword Box, there was a line of cryptic message engraved: Using Qi as a sword, one can control the heavens and earth.
The cryptic message wasn't truly words; it could express many complex meanings.
With Gao Xuan's knowledge of cryptic messages, he could only understand the shallowest layer. Moreover, it was entirely his personal interpretation.
If someone else were to interpret it, they might come up with a completely different understanding.
Gao Xuan roughly understood the meaning: the Celestial Spirit Sword Box believed Source Power was the most formidable, and one should use power to wield the sword, implying that as long as one's strength was great enough, any enemy could be defeated.
If unable to resolve it, it meant the strength was still insufficient.
Gao Xuan, despite his experiences from two lifetimes, had never heard of the Celestial Spirit Sword Box. However, this object seemed far from ordinary.
