The next trial by Flender's order sealed bond deeper. Teams faced contrived siege scenario—holding hilltop against wave after wave of spirit beast proxies conjured by teachers. Students fought furiously. Tang San's nets snared dozens, Mubai roared tiger strikes, Hongjun blasted flame. But enemies kept coming, pressure heaping heavy.
At peak, Tang San shouted, "Too many! We need wall!" Without pause, Leng Xue stepped forward calmly, unleashing third ring. Mist condensed immediately into shimmering Glacial Barrier across slope. Beasts slammed into wall, claws screeching against ice but failing to break. Behind its shelter, Tang San extended grass creepers freely, weaving traps unhindered. Mubai and Hongjun struck with timed bursts safely.
The synergy awed everyone. When frost wall cracked faint, Tang San's grass wrapped it, reinforcing pattern. Blue silver wound through transparent sheet like design carved onto glacier. For spectators, the sight looked like nature itself conspired—a living fortress of grass and ice. Zhao Wuji bellowed laughter, incredulous. Flender muttered, "That's… something even veteran squads dream."
Wave collapsed soon after. Students staggered victorious. Tang San turned, face calm but eyes burning faint respect. "Without your wall, my grass would fail before sprouting." Leng Xue bowed slightly, answering: "Without roots, frost alone crumbles."
For the first time, public recognition was undeniable. Mubai admitted openly, "Frost Brother, your place is real." Hongjun teased less and grinned wide. Rongrong said softly, "I will stand behind that wall anytime."
Leng Xue only smiled quietly. Noise around him meant little. What mattered was that frost and grass together had interwoven, two boys born same day—destinies closer now. Tome inside soul blazed words: Joint Heritage Bond Secured. Dual‑Path Synchronization Initiated.
Beneath moon, while others slept in victory fatigue, Xue carved into Shrek Frost Wall new inscription by his hand: Frost and Grass endure together. Roots eternal against flame. He stepped back trembling, nose stinging with old memories. Ancestor Tian had dreamed heritage survive. It now lived strong among monsters, recognized, enduring.
