God-Killing Blood Sword

The God-Killing Blood Sword is the enormous black sword that Wei Sheng finds in the sealed battlefield and carries to the height of his sword path. It consumes blood and other energies, preserves the power and fighting impulses of ancient warriors, and acts independently when its wielder is in danger. Its strength is therefore inseparable from its risk: the sword repeatedly tests whether Wei Sheng controls its inherited savagery or is controlled by it. (Chapters 341, 525–526, 682, 721–733, and 776)

History

The sword in the ancient battlefield

Wei Sheng discovers the weapon in the ancient battlefield as a huge, unadorned black sword of unknown grade. It is heavy enough to suit his direct physical training and initially gives no complete explanation of its nature. He carries it through the battlefield and out into later journeys, where its ability to swallow soul base source, cloud essence, and blood gradually distinguishes it from an ordinary flying sword. The sword grows through what it consumes, but its origin and name remain hidden during this first phase. (Chapters 341, 353, 525–526, and 591)

Blood, the kill order, and the sword's name

On Wei Sheng's solitary road through mo territory, the weapon drinks the blood of attackers and becomes increasingly active. A kill order forces him through repeated lethal challenges, giving the sword abundant blood while giving Wei Sheng opponents against whom he can temper his path. When news of Wu Kong Sword Sect's destruction turns his grief into a breakthrough, the weapon finally reveals itself as the God-Killing Blood Sword. Its blood streaks carry the shen power and battle intent of ancient totem warriors, joining Wei Sheng's newly formed Void Sword Domain in the killing of a Kun Lun assassin. (Chapters 591, 663–666, and 682)

Blood Curtain and the warrior-blood transformation

After Wei Sheng incorporates the shen-power method sent by Zuo Mo, he uses the sword as the focus of Blood Curtain. The strike combines all his available ling and shen power with almost one fifth of his own blood to cut through the Sky Lightning Branch and three enemies. It succeeds but leaves him defenseless. The sword responds on its own, draws him underground, and returns stored blood so that he does not die. (Chapters 719–722)

The rescue becomes a transformation rather than a simple replenishment. Inside a blood cocoon, the sword replaces every drop of Wei Sheng's blood with blood collected from ancient warriors. Each drop contains power together with the former warrior's belief and hatred, an inheritance described as fatal poison to an ordinary soul. Wei Sheng survives because his sword heart preserves his identity, leaving weapon and wielder more deeply connected while increasing the burden he must govern. (Chapter 733)

Backlash, awakening, and god-level battles

The bond does not make the sword obedient. While fighting an ancient creature in the Black Sea, it turns its accumulated savagery against Wei Sheng's mind. He anchors himself in his memories and commitments, retakes control, and uses the sword to release an attack that parts the sea and kills the creature. The weapon then consumes the beast's blood and extracts shen power from its flesh, showing both its value as a source of recovery and its continuing hunger. (Chapters 776–777)

Against Tian Huan's Chief Elder, the sword awakens more completely and pours the blood and fighting instincts of its ancient warriors into Wei Sheng. It can move his body and select attacks, but inherited aggression proves less precise than Wei Sheng's own understanding. He reasserts control and uses increasingly compressed Void sword essence rather than surrendering his judgment to the weapon. After Shi later implants a dragon heart in Wei Sheng, its exceptional blood production gives the sword a sustainable source without removing the need for mental mastery. (Chapters 838–845 and 880)

At god level, sword, dragon heart, and Wei Sheng's purified sword essence function together through his battle with Lin Qian and the campaign that reaches Kun Lun's main peak. The corpus still treats Wei Sheng—not the weapon's stored instincts—as the decisive mind. When he understands the sword as a means to protect the living rather than merely avenge the dead, the violence within his sword essence becomes peaceful without losing force. The sword remains in his hand at its final documented appearance during the attack on Kun Lun. (Chapters 903–905 and 909)

Abilities and properties

• Energy consumption and growth: The sword consumes blood, soul base source, cloud essence, and energy from powerful creatures. It can extract shen power from flesh and use what it has stored to support later attacks or recovery. The text does not establish a fixed capacity or conversion rate. (Chapters 341, 525–526, 591, and 776–777)
• Stored blood: It preserves blood and can return it to Wei Sheng when he is near death. Its more extreme blood-cocoon transformation replaces his blood with that of ancient warriors, transmitting power as well as dangerous beliefs and hatred. This is not a harmless healing effect; survival depends on the strength of Wei Sheng's identity and sword heart. (Chapters 721–722 and 733)
• Ancient warrior inheritance: Blood streaks released by the sword carry the shen power, instincts, and accumulated combat experience of ancient totem warriors. The inheritance can enhance Wei Sheng's body and attacks, but when it takes control its savagery is less exact than his own sword understanding. (Chapters 682 and 838–845)
• Independent action and sentience: The sword pulls Wei Sheng out of danger, returns blood, demands or seeks energy, bargains through appetite, and attempts a mental backlash. These actions establish agency, but the corpus does not provide a separate personal name or a complete account of its consciousness. (Chapters 721–722 and 776–777)
• Weapon corrosion and cutting power: Its blood and sword energy can corrode opposing weapons and join Wei Sheng's Void sword essence in attacks that cut shen techniques, spatial defenses, massive creatures, and terrain. The largest late feats also depend on Wei Sheng's god-level cultivation, dragon heart, and comprehension, so they are not properties of the sword alone. (Chapters 682, 719–722, 776, 905, and 909)
• Costs and limitations: The sword's hunger encourages lethal accumulation; major blood techniques can leave Wei Sheng empty; stored warrior intent can poison or overwhelm the mind; and the weapon has directly attempted to seize control. Even after their bond deepens, Wei Sheng must govern it through an unusually stable sword heart. (Chapters 663–666, 721–722, 733, and 776)
