The Poisonous Velvet Knife now qualifies to compete with those Relics for an equipment slot, and Mu You has just freed up a new slot after upgrading, placing the Poisonous Velvet Knife into it immediately.
[You have equipped the Poisonous Velvet Knife, current equipment slots (5/5): Omniscient Crystal, Synthesis Furnace, Arm of Wind Kirin, Sunlight Affinity, Poisonous Velvet Knife.]
The synthesis process in the Synthesis Furnace must also be carried out in the equipment slot, no need to dismantle it for now; Mu You carelessly threw some useless materials into it to slowly try his luck, and then controlled his character to set off.
Since the Poisonous Velvet Knife can no longer use spider silk for synthesis, continuing to hunt Poisonous Velvet Spiders is pointless. Fortunately, there are still many High Star Monsters in these mountains, so there's no shortage of targets to grind.
