Kaspar spent countless iterations dying in the corridor beyond the gate, learning the rhythm of wyvern attacks through painful repetition. He tried warning officers and students, but his lack of status marked him as insane or a coward. Each reset returned him to the tent, retaining only his memories and accumulated physical fatigue. He stole a sword from an officer's tent after multiple failed attempts to get weapons legally. In the loops, he trained relentlessly in secluded areas, refining his Amateur Swordsmanship until the system recognized his effort. He met Iris, a Second Circle Mage who became his guide to the world's magic system. She explained the concept of Circles and mana cores, revealing his unique condition of having nine cores but zero Circles. Through trial and error, he discovered he could not project mana but could internalize it via Mana Breath. This technique allowed him to bypass the need for Circles, granting him enhanced physical capabilities. However, the technique was inefficient compared to standard magic. Despite his growing power, he remained trapped in the dungeon loop. He realized that simply surviving the gate opening was not enough to break the cycle. He needed to change the outcome fundamentally. Every death taught him something new about the enemies or the environment. Eventually, he managed to wound a wyvern, unlocking new resistance stats. Yet the loop persisted. He needed more than survival; he needed purpose. The constant pain of resetting began to wear on his sanity. He questioned whether escape was possible or if this was his eternal punishment. The system messages became his only companions in the darkness. He vowed to protect those around him despite the futility. His resolve hardened with each resurrection. He prepared for the ultimate challenge ahead.

Varen, a prince, requisitioned Kaspar for the Iron Cross special legion, sending him to the Coliseum for brutal training. Here, Kaspar fought in the arena against other recruits and mutants, gaining fame for non-lethal victories. He encountered Marcus, Gerret, and Lyra, forming a bond with fellow slaves who sought freedom. The monks of the Iron Cross believed mana was poison, viewing Knights as martyrs who sacrificed their souls to fight. Kaspar struggled with the morality of slavery but focused on survival. He learned Mana Blood from Wendt but found it incompatible with his existing Mana Breath. During training, he accidentally killed himself testing the combination, triggering a penalty from the Sin of Sloth. He lost days of time but survived. Varen recognized Kaspar's potential and offered him field deployment instead of continued confinement. Kaspar chose the front line to prepare for the impending apocalypse. He was assigned to Grenzheim, a garrison town near the elven border. There, he met refugees from another continent speaking Russian. These refugees hinted at a deeper conspiracy involving the elves and orcish slave trade. Kaspar used his knowledge to aid them, earning their trust. The countdown to humanity's end ticked down relentlessly. He trained harder, pushing his body to the limit. The Iron Cross tested his loyalty and skill constantly. He proved his worth through action rather than words. The path to the front was fraught with danger. He faced mutated beasts on the road. He arrived at the trench just in time for bombardment. The war was real and unforgiving.

Deployed to the trenches, Kaspar witnessed the elven bombardment and the destruction of the defensive grid. He spotted humans running through the minefield, realizing they were escaped slaves. He saved five refugees, including Yulia, and brought them to safety in Grenzheim. A linguist confirmed they came from the eastern continent via orcish trade. The elves were acquiring slaves for a specific purpose. Kaspar noticed a connection between the refugees and the apocalypse countdown. He sensed their presence on the morning the timer reached zero. They vanished from the lodging house. Panic set in as the bells rang across the city. An archmage hovered above, erasing reality with a sphere of light. Kaspar rushed to the front but arrived too late to stop the initial strike. He rode hard to intercept the refugees. He found them on a hilltop performing a ritual to counter the elven magic. They intended to sacrifice themselves to save the world. Kaspar tried to stop them but was repelled by the dome of energy. The ritual required their lives to fuel the barrier. He understood the cost of victory. The refugees were willing to pay it. He watched helplessly as the pillar of light rose. The fate of humanity rested on their choice.

Kaspar reached the hilltop as the refugees completed their circle. Yulia argued with Pyotr about proceeding with the plan. The old man insisted on finishing the ritual to save the city. Kaspar attacked the dome but his blade shattered against the energy. He attempted to use Mana Breath to disrupt the flow but the density was overwhelming. The dome expanded, sealing the four figures inside. Yulia begged for forgiveness, knowing she could not stop it alone. Kaspar realized the ritual was designed to counter the archmage's erasure spell. If successful, it might neutralize the threat entirely. However, the cost was the lives of the refugees. He hesitated, torn between saving them and saving everyone else. The archmage formed a second sphere above the city. Time ran out. The refugees accepted their fate. The light intensified, blinding everyone nearby. Kaspar braced for the impact. The clash of magics threatened to tear the world apart. He prepared to jump into the dome if necessary. The outcome hung in the balance. The world waited for the explosion.
