The basement of the royal library smelled of vinegar, rotting sheepskin, and the bitter grease of cheap tallow candles. Xiao Chen did not look up when the heavy oak door grated against the floorboards. He remained hunched over a three-hundred-year-old celestial map, his ink-stained fingers twitching as he recalculated the alignment of the dead stars.
"You are dripping blood on my floorboards, Emperor," Xiao Chen said, his voice like dry autumn leaves scraping along a wall. "The high-tier Earth energy you stole from the Old Wolf is leaking out of your pores. It is highly offensive to my herbs."
Lin Feng closed the door behind him, the iron latch clicking into place. He pulled back the collar of his tunic, revealing the dark violet ring that had burned itself into his skin. The mark looked like a twisted rope, slightly puckered at the edges as if it were actively sinking into his throat. "I don't have time for your sensibilities, scholar. Look at the frequency. It tightened three millimeters after the battle ended."
Xiao Chen finally dropped his charcoal stick. He squinted through his brass spectacles, leaning so close to Lin Feng’s neck that his greasy topknot brushed the prince's chin. He reached out with a silver-tipped probe, tapping the edge of the violet brand. A sharp, clear note, like a struck crystal glass, echoed through the damp room.
" Fascinating," Xiao Chen muttered, turning back to his desk to flip through a stack of loose parchment. "The system isn't just measuring your internal Qi volume anymore. It has anchored itself to your nervous system. It is waiting for a trigger."
"What kind of trigger?" Lin Feng asked, sitting heavily on a stack of unBound encyclopedias. The paper groaned under his newly increased physical weight. "The countdown has seven years left. Why is the noose tightening now?"
"Because you are growing too fast," Xiao Chen said, throwing a handful of dried salt into a bronze brazier to clear the sulfur smell from the room. "The prophecy is an equation, you absolute fool. You think you are a hero conquering empires, but to the entities who built this lattice, you are simply a pig growing fat enough for the festive knife. Every time you absorb a king’s cultivation, you speed up the maturation process."
Lin Feng rubbed his eyes, his knuckles catching on the crust of dried mud from the western flats. "If I stop cultivating, the neighboring sects will overrun the capital by winter. If I continue, I speed up my own execution. Give me a solution, Chen. I didn't pull you out of the imperial dungeon just so you could call me a pig."
"The solution requires a variable we don't possess," Xiao Chen said, his voice dropping as he dragged a heavy, iron-bound volume from the bottom shelf. The cover was wrapped in dried skin that didn't belong to any animal found in the central plains. "I have been translating the third layer of the star map you described. The cosmic array requires a specific resonant frequency to open the world-shield during your death. It isn't just about the second or the hour. It is about the emotional state of the executioner."
Lin Feng frowned, his hand dropping from his neck. "My vanguard general is loyal. Zhang Wei will take my head if I command it. He will hate every second of it, but his hand won't shake."
"Zhang Wei won't work," Xiao Chen said, his fingers flying through the pages, leaving black smudges on the ancient text. "The array won't accept a soldier's obedience. Obedience is cold. It lacks the necessary spiritual friction."
"Then I will hire an assassin from the southern marshes," Lin Feng said, his voice turning sharp with irritation. "Give them ten thousand spirit stones to drive a needle through my temple at the exact stroke of midnight."
"An assassin is even worse," Xiao Chen hissed, finally slamming his palm down on the page. The candles flickered, nearly dying out in the draft. "An assassin feels nothing but greed or professional pride. The array requires a violent disruption of the natural soul-bonds. It requires a specific type of agony to shatter your god-realm core and turn it into the shield."
Lin Feng stood up, his white fire core flaring slightly, causing the ink pots on the desk to rattle against each other. "Speak clearly, scholar. The numbers in my head are already moving."
Xiao Chen looked up from his ancient scrolls with a pale face, his fingers trembling so hard he had to tuck them into his wide sleeves. "The text is explicit, Lin Feng. The person holding the blade cannot be an enemy, and they cannot be a servant following orders. To trigger the celestial rupture and save the realm, you must be killed by someone who loves you completely."
