### Chapter 20: The Fire Titan
Sun Han and Mia fought tirelessly against the monstrous giants, their bodies and minds pushed to their limits. The hell flame continued to blaze in Sun Han's hands, scorching any giant that dared to come close. Meanwhile, Mia's rare-grade dagger flashed with deadly precision as she struck at the weak points of their towering enemies.
As they fought, Sun Han noticed a giant that stood out from the rest. It was significantly taller, towering at an imposing 20 meters. Its presence exuded a sense of dread that made Sun Han's blood run cold. The giant locked its fiery gaze on him and let out a thunderous roar that shook the ground.
The giant's fist ignited with intense flames, turning it into a blazing weapon. Sun Han barely had time to react as the fiery fist hurtled toward him. He leaped to the side, narrowly avoiding the devastating blow that left a massive crater where he had stood just moments before.
Sun Han's heart pounded in his chest as he glanced over to Mia, who was engaged in a fierce battle with a 5-meter-tall titan. She moved with incredible agility, dodging the titan's powerful strikes and countering with swift, precise cuts from her dagger. The sight of her fierce determination gave him renewed strength.
Focusing on the towering fire titan before him, Sun Han launched himself at the beast with his katana drawn. He aimed for its legs, hoping to bring it down. The blade slashed through the titan's foot, causing it to roar in pain and stagger backward. However, to Sun Han's dismay, the wound began to heal almost instantly.
Before he could react, the titan lashed out with a swift kick, catching Sun Han in the stomach. The force of the blow sent him flying through the air, crashing into a tree with such impact that it shattered upon contact. Sun Han hit the ground hard, gasping for breath and coughing up a mouthful of blood.
Struggling to his feet, Sun Han wiped the blood from his mouth and analyzed the titan's movements. His keen eyes noticed something crucial: a red, beating heart visible through the titan's semi-transparent chest. The heart pulsed with life, seemingly the source of the titan's regenerative abilities.
Realizing the heart was the key, Sun Han steeled himself for another attack. Summoning the hell flame, he launched himself at the titan once more. This time, he aimed directly for the heart. With a mighty swing of his katana, he drove the blade into the titan's chest, piercing the heart with deadly precision.
The titan let out a final, agonized roar before collapsing to the ground, its body lifeless. A system prompt appeared before Sun Han:
**"You have killed a level 5 tier 0 Mutated fire titan and gained level 1 passive ability Regeneration."**
