Just as Zhang Yu asked out of curiosity, Ying Xin proactively provided an explanation for her.
After all, Ying Xin is a local from the Second Floor and had watched many live streams of competitions before entering the university.
Accompanying Ying Xin's narration, the competitors in the next match demonstrated various flying sword techniques.
Nether University's living flying sword flew and fought as if it were a living creature, locking onto targets.
Vajra University's Eye of the Law flying sword could guide the flying sword by directly seeing the target across 80 kilometers.
Wanfa University's flying sword communicated with the Spirit Realm Network through the celestial bodies, locking onto targets.
It was at this moment that Zhang Yu realized that Kunxu Second Floor's sun and moon were actually engineered by Wanfa University.
Both the sun and moon are enormous magic treasures, constantly maintaining a Spirit Realm Network that covers the entire Kunxu Second Floor.
