The Tightening Fillet Mutates, Defying Fate

Lin Zhu nearly burst out laughing after reading the mutation details, especially the first effect, "Inverting Yin and Yang"! Good heavens! Head massage? Increased cultivation? This wasn't a Tightening Fillet Spell at all—it was clearly a VIP Cultivation Accelerator! It could even muddle the Heavenly Secrets? As expected of something produced by the system: wicked enough, and... considerate enough!

Without hesitation, his gaze swept over the mutation requirements. "Ten thousand drops of Merit Divine Water? I just got it—I haven't even had time to warm it up. A Houtian Supreme Treasure containing the laws of 'imprisonment' or 'protection'..."

His thoughts raced, and he immediately recalled something lying in the corner of his System Space, something that had remained "locked" all this time—a treasure he had casually pilfered while "treasure hunting" in the Western Heaven: the Muni Light Pearl! This thing was a Buddhist treasure blessed by Amitabha, containing supreme steadfastness and protective Buddha Light. It absolutely qualified!

"Sacrifice it! Mutate it immediately!"

Lin Zhu silently commanded in his heart.

[Confirm sacrifice of 'ten thousand drops of Merit Divine Water' and the Houtian Supreme Treasure 'Muni Light Pearl'...]

[Sacrifice successful! Beginning mutation...]

[Mutation complete! Obtained: Tightening Fillet!]

Almost the instant the system notification ended, Lin Zhu sensed that the dark golden ring within his Universe in the Sleeves had undergone some fundamental, unfathomable change in the structure of its internal laws. Though its appearance and aura remained exactly as before—cold, ancient, carrying a faint sense of restraint—its core was now utterly different.

"Tsk, tsk, this effect... Even I want to try wearing it myself."

Lin Zhu secretly chuckled. This thing was practically a divine artifact for scamming people... no, for helping people cultivate!

Sure enough, the system immediately issued a new task.
