### Chapter 19: Is This Attack on Titan?
Sun Han and Mia navigated the throng of people who had gathered after the intense boss battle. They walked with purposeful strides, weaving through the clusters of survivors who were either celebrating their victory or recovering from their injuries. The adrenaline was still pumping through their veins, but they knew they needed to get back home to regroup and assess their situation.
The journey back to their underground base took about an hour. The landscape was eerily quiet, the remnants of the battle stark against the backdrop of the apocalypse. Strange creatures roamed the area, but none dared to approach the pair, sensing the aura of strength and determination emanating from them.
Once inside their shelter, Sun Han felt an overwhelming urge to open the mysterious black star treasure chest he had obtained during the battle. His heart raced as he lifted the lid, revealing a glowing orb of deep crimson light. A system prompt appeared before him:
**"You have gained a special-grade bloodline. Do you wish to absorb the demon bloodline?"**
Without hesitation, Sun Han uttered a firm, "Yes."
A surge of energy coursed through his body as he absorbed the bloodline. Another system prompt appeared:
**"You have gained the Demon Bloodline. Absorption at 1%. You will gain new abilities as the absorption percentage increases."**
Sun Han watched in awe as the percentage slowly climbed to 1%. At this initial stage, he felt a slight change in his senses and physical strength. A new skill unlocked in his mind: **Hell Flame, Drain 10 Mana **. He held out his hand, and flames erupted from his palm, burning with an intense, otherworldly fire. The flames flickered out as he regained control, leaving him breathless and awestruck.
"Sun Han, you're glowing," Mia said, her voice a mix of admiration and curiosity.
"Yeah," Sun Han replied, still marveling at the power he now possessed. "I feel... different. Stronger."
Mia, not wanting to be left out, opened her own treasure chest. Inside, she found a rare-grade dagger, its blade shimmering with an ethereal light. She held it up, examining the fine craftsmanship and the intricate runes etched into the metal.
"This will come in handy," Mia said, slipping the dagger into her belt. They exchanged a determined glance, knowing they were now better equipped for whatever lay ahead.
Deciding they needed rest before the next wave, Mia claimed the sofa while Sun Han, ever the pragmatist, took the bed. "I'm not giving my bed up to anyone," he declared with a smirk.
They both drifted into a deep sleep, their bodies recovering from the recent battle. The underground base was silent, a temporary sanctuary amidst the chaos of the apocalypse.
Several hours later, a loud rumble shook the shelter, jolting them awake. They quickly gathered their gear and prepared to face the new threat. As they emerged from the underground house, the sky was filled with massive rocks hurtling towards the ground. Each rock exploded upon impact, revealing giant, naked monstrosities with no private parts. The sight was both bizarre and horrifying.
"Wave 2 begins now. 100,000 mutated Tittans."
Sun Han's eyes widened in disbelief. "Is this fucking Attack on Titan?" he muttered, unable to comprehend the sheer scale of the creatures before them.
The monstrous giants roared, their voices echoing across the landscape. They moved with a terrifying grace, their eyes fixed on the humans below. Sun Han and Mia stood their ground, ready to fight.
"We've got to take them down," Mia said, gripping her dagger tightly.
Sun Han nodded, his mind racing with strategies. He focused on his new ability, willing the demon bloodline to awaken further. But for now, he would have to rely on the hell flame and his katana.
The first giant lunged towards them, its massive hand reaching out to crush them. Sun Han reacted instinctively, summoning the hell flame. A torrent of fire erupted from his hands, engulfing the giant's arm. The creature roared in pain, staggering back as the flames consumed its flesh.
