Chapter 174 Part 2: The Demon King’s End ----- “{Blood Burst}!” BOOOMMM!!! Heisenberg blew up from the inside; the pressure of his insides exploding with the crimson blood Scarlet conjured was enough to fracture most of his bones, while his arms flew off into pieces, revealing a bright red crystal hiding beneath his ribs, which had gained a couple of cracks. “That’s… It must be his Demon King’s Heart?” Demon King’s Heart is a crystallization of a Demon King’s powers hidden inside their chest. The reason why Heisenberg could become undead without needing flesh or internal organs anymore was simple: with this core, he could take any form, anybody, any shape, no matter what. To truly kill a Demon King, you had to shatter their heart and destroy their Soul Inside. “Jeremias!” Without wasting a single second, Anna summoned the weakened Jeremias, who, with a simple mental command, shifted space between her and Heisenberg, cutting the space between her, Jack, and the skeleton in less than a split second, virtually teleporting her to his side before he could react in time. FLASH! “Now, Jack!” “You don’t have to tell me!” Jack harnessed all his power into his corrupted Gram, the sword gaining a few cracks over the overuse he had put it through. A pillar of black and swirling crimson colors surged, piercing the skies, and then descending towards the Demon King’s Heart. SLAAASH! At the same time, Anna combined her {Radiance}’s Traits effects together, greatly boosting all her capabilities as a ferocious crimson snake surged from her sword’s slice, swiftly combining with Thousand Blades, and multiplying into hundreds, biting and draining the energy of the spherical core. BOOOM! Both attacks blew off a few more of Heisenberg’s bones, while his core gained even more cracks! But it had yet to explode. The shadows and phantasmal flames he vomited quickly transformed into a giant skeletal claw, attempting to rip both siblings to shreds. “If you won’t pity me, then I don’t need you at my side!” With a scream of both sorrow and frustration, Heisenberg attacked. Both siblings defended with barriers made out of their Radiances and their skills. An explosive strike shattered most of their defenses, but they survived somewhat. CRAAASH! “Shit, he’s tough as bricks even after we ate like half of Uroboros!” Fenrir complained. “Well, not like we can use even half of what we got out of that damn worm! Dammit, alright, Jack, fuck it!” “We’re doing it?!” Jack asked. “Yeah! Let me enter the damn fight! I won’t let your world be engulfed by any monster other than myself.” Fenrir laughed. His shadows surged out of the wounded Jack. Anna noticed the demon wolf completely devour her brother and then change him. His werewolf form swiftly transformed into an even more beast-like appearance; a second pair of arms emerged, all of them materializing giant black claws; his size was tripling; he now possessed three heads instead of one, with six eyes, three brains, and lots of processing power. “W-What is that form?!” Anna thought, not in all the novels she ever read of Jack taking on such a transformation before. “Was this form created not through forcing Jack to grow stronger, but through his bond with Fenrir?! It’s so strong, yet... it doesn’t even feel like it’s draining his soul away.” “RAAAHHH!” With a mighty roar, the protagonist kicked the sky, and an enormous explosion of shadows was released from his steps into the air, his claws rushing down towards Heisenberg, whose soul started leaking out of his cracked core. “Leave me alone!” While screaming, the Demon King attacked Jack with his soul, which transformed into a red titan of demonic flames, punching Jack’s entire body, only for the three-headed and six-armed werewolf to attack back. CRASH! CRASH! CRASH! Three powerful claw slashes were enough to cut through the blazing demonic soul manifestation, followed by Jack’s only sword-wielding arm swinging down at Heisenberg. “DIE!” With a mighty roar, an explosio
