Chapter 6542: All-slaying Saber The blade needed but one swing to draw blood for the world canvas. For spectators, seeing the blood of an immortal would be both an honor and a disaster since each drop contained untold energy. Lower cultivators weren’t worthy of being struck down by the blade, only immortals. The sky changed color upon its presence. The immortal engulfed in flames also pulled back, showing palpable apprehension despite not seeing the blade’s master yet. “Calamitous Edge.” A primal ancestor lowered his head in fear. The blade's name was known to all; its presence made people’s throat dry. Immortal-level weapons couldn’t always kill an immortal. This was one exception. 𝕗𝚛𝚎𝚎𝐰𝗲𝗯𝗻𝚘𝚟𝚎𝗹.𝕔𝐨𝕞 Several still existed in Three Immortals - Firebringer Hatchet, Mountaincutter... These weapons could slay primal ancestors easily. When Black used Firebringer Hatchet, he could contend but not kill an immortal. Xian Chengtian had some left behind by his masters, one of which was Immortal Killer Spear, granting him the qualification to fight an immortal. Putting overlords aside, immortals couldn’t guarantee a kill using these weapons against their equals. However, Calamitous Edge’s murderous potential exceeded them all, ranking first among the known immortal weapons. This was no exaggeration since it struck fear into the immortals of the past and present, even the legendary true immortals. Its appearance shocked everyone including the immortals in hiding within Three Immortals. “She’s here, Desolate Ancestor!” A spectator said. Only one being had ever wielded this weapon - Desolate Ancestor, the most respected cultivator in Three Immortals and the founder of the immortal path. “Ancestor.” Many knelt for a long while. Even those from Supreme Heaven had nothing but respect for her. Her weapon alone invoked acts of reverence throughout Three Immortals - a testament to her prestige. Given her current cultivation within the immortal realm, she no longer needed to use this ace card. The mightiest supreme overlords weren’t worthy of tasting the blade. Xian Chengtian observed the fight and knew his immortal weapons wouldn’t be able to stop the blade from decapitating him. Only the two immortals from the redemption grounds could stop her blade. Zhan Sansheng could as well but he was no longer alive. The fiery immortal found himself in a tough position. Escaping was difficult while being targeted by Desolate Ancestor. “Show yourself.” Her voice echoed and suffocated listeners. All eyes were on the fiery immortal, feeling a bit strange since they all knew who he was. “Bao Pu, you won’t get away today. Why do you not show your face?” Black asked. The figure didn’t react.
