In the Demon Realm, the city of Blood Massacre was located in the northwest, a territory under the rule of the Western Demon Lord, Li Wuji. Since the battle at the border of the Immortal Realm, where the True Martial Demon-Suppressing Great Emperor, relying on the Big Dipper Seven-Star Formation, single-handedly faced four opponents and shattered the Four Spirits Blood Formation jointly set up by the four Demon Lords, leading to a crushing defeat for the Demon Realm, the Western Demon Lord's forces had suffered the heaviest losses! Not only was the Western Demon Lord, as the supreme commander, stripped of his physical body, but nearly all of his hundred-thousand-strong army was annihilated, leaving only ten thousand personal guards stationed in Blood Massacre City. Such weakened strength undoubtedly made him the target of constant covetousness from the other three Demon Lords day and night.
After retreating back to the Demon Realm and returning to his lair in Blood Massacre City, the Western Demon Lord hastily went into seclusion to heal his wounds. While the Western Demon Lord was in seclusion, unaware of the outside world, the other three Demon Lords were each plagued by headaches in their own territories. During the war with the Immortal Realm, a mysterious demon had suddenly emerged in the Demon Realm. No one had seen his appearance, and no one even knew his exact strength. All that was known was that this demon, single-handedly, had killed several Demon Generals left behind in the territories of the Eastern, Northern, and Southern Demon Lords, shocking the entire Demon Realm!
At that moment, in the dark sky of the Demon Realm, an extremely faint shadow was streaking through the air at great speed, heading straight for the Western Demon Lord's territory, Blood Massacre City. "Once I devour a few more Demon Generals under the Western Demon Lord, I'll break through to the Ninth-Rank Demon General, hahaha!" This faint shadow was the great demon that had recently thrown the Demon Realm into panic. He had no fixed form, merely a faint silhouette, now riding demon clouds and advancing swiftly.
Soon, the shadow reached the Western Demon Lord's territory, Blood Massacre City, and descended in a remote corner. It attached itself to a soldier from a patrol squad outside the city and swaggered into the city with the group. "Any disturbances outside?" After the patrol squad returned to the barracks, the Great General left in charge of the city by the Western Demon Lord immediately inquired. "Reporting to the Great General, everything is normal. No suspicious persons found," the squad leader said respectfully to the Great General. "Keep a tight watch. No mistakes are allowed while the Demon Lord is in seclusion. Understood?" The Great General's stern gaze swept over every soldier in the squad as he spoke gravely. "Yes!"
No one noticed that after this squad left, an almost transparent shadow quietly merged into the shadow cast by the Great General on the ground. "Sigh, I wonder when the Demon Lord will recover." Returning to his tent, the Great General under the Western Demon Lord sighed and sat alone. Just then, a strange voice reached his ears. "Where is your Western Demon Lord in seclusion?" "Who! Ah!" The Great General barely managed a shout of surprise before his own shadow pierced through his body, and he collapsed to the ground as a dried corpse.
A shadow, now much more condensed, slowly took human form, staring at the dried corpse at his feet. After absorbing the other's memories, he licked his lips and muttered to himself, "So the Western Demon Lord's physical body is destroyed, and only his primordial spirit remains. Heaven helps me!" The shadow reattached itself to the dried corpse on the ground, and a bizarre scene unfolded! The muscles of the corpse, which had been completely lifeless, began to swell again, and it slowly rose from the ground! "Crackle!" Stretching the bones of his entire body, the resurrected Great General wore a sinister smile as he walked out of the tent and headed toward the palace in Blood Massacre City.
"Greetings, Great General!" Along the way, every demon guard in the palace bowed respectfully upon seeing the Great General, for he was the Western Demon Lord's own brother, Li Wushang! The possessed Li Wushang made his way to a secret chamber and asked the guards standing on either side of the door, "How is my elder brother?" "Reporting to the Great General, the Demon Lord has been in seclusion since his return. We subordinates do not know his current condition." These two were trusted confidants of the Western Demon Lord, and they bowed respectfully to Li Wushang as they spoke. "Open the door. I have urgent matters to report to my elder brother!" Li Wushang said expressionlessly to the guards.
"This... Great General, the Demon Lord ordered that no one is to disturb his seclusion!" The guard in charge of the door looked troubled, addressing the Great General who held power second only to the Demon Lord. "Is that so? Then you're useless!" Two shadows suddenly flew out from Li Wushang's body and sank into the guards' foreheads, causing them to slowly collapse to the ground! Bending down to fumble through one guard's belongings, he found the key, easily opened the door to the Western Demon Lord's secluded chamber, and stepped inside.
The chamber was dim, with only two lamps lit beside a soft couch ahead. In the faint light, Li Wushang saw the Western Demon Lord, reduced to his primordial spirit. "Wushang, didn't I order that no one was to enter?" Hearing the noise, the Western Demon Lord's primordial spirit opened its eyes. Upon seeing his brother, a hint of displeasure still crossed his face as he spoke. "Elder brother, today a mysterious demon called the Shadow Demon has appeared in the Demon Realm. Some time ago, this Shadow Demon went on a killing spree in the Eastern Demon Lord's Boundless City, the Southern Demon Lord's Bone City, and the Northern Demon Lord's Demon Martial City, assassinating dozens of Demon Generals. Even the three Demon Lords personally intervened but failed to capture him. He remains at large." Li Wushang looked calmly at the Western Demon Lord's primordial spirit and reported this major news.
"What! The three Demon Lords couldn't catch him? Where is this Shadow Demon now? Go investigate immediately!" The news from Li Wushang immediately terrified the Western Demon Lord. If even the three Demon Lords couldn't handle him, the Shadow Demon's strength must be terrifying! "Elder brother, I know where the Shadow Demon is now." The Shadow Demon-possessed Li Wushang smiled eerily, looking at the Western Demon Lord's primordial spirit. "Oh? Where is he?" "Heh, my good elder brother, I'm right in front of you!" As the Western Demon Lord finished speaking, his eyes widened in horror, for he saw his brother suddenly turn into a dried corpse and fall to the ground! "You're the Shadow Demon! You, you, you... don't come near!" The terrified Western Demon Lord, reduced to his primordial spirit, stammered in front of him. "From today on, the Demon Realm will have no more Western Demon Lord! Hehehe!" A massive shadow instantly engulfed the Western Demon Lord's primordial spirit, wrapping it tightly. "Ah! Ah!" The Western Demon Lord's primordial spirit let out a piercing scream, but no matter how it struggled, it couldn't break free from the shadow's grip, and it began to shrink rapidly!
Minutes later, the screams in the chamber abruptly ceased, and silence returned. A shadow slowly coalesced into a form, different from before—this shadow radiated a sinister blood-red light, its eyes also turning blood-red. It extended a crimson tongue, licking its lips as if savoring the taste of the Western Demon Lord's primordial spirit. After a long moment, the blood-red figure spoke slowly: "From today on, the entire Demon Realm will kneel before me, the Blood Shadow Demon Lord!"
