Yu Kai watched nervously in panic. The massive bull head exuded a ferocious aura that sent shivers down his spine. He then hurried to decipher the ancient characters on the tower. They were ancient and mysterious, their shapes twisted and complex. His heart instantly sank. "Gate of Hell! This must be the Gate of Hell! Am I dead?" he muttered in disbelief, his eyes filled with confusion.

The next words of the guarding general further confirmed his guess, "Welcome everyone to the Ghost Gate. I, Niu Tou Abang, will be responsible for picking you up." General Niu Tou's voice rang out outside the city gate like a loud bell, making everyone's ears buzz.

Although everyone had suspected this, the realization that they were dead was still like a bolt from the blue, causing their emotions to collapse and spiral out of control. Some people cried hysterically, "No, this can't be true! How could I possibly die? I want to go back!"

As soon as they turned around to flee, a dense rain of arrows was shot out from the top of the city wall. No matter whether they were people or giant beasts, they were hit by an arrow. They were pierced by the long arrows, and let out miserable roars. Their bodies turned into points of light and dissipated in the night.

This action terrified everyone. Some knelt before the Bull-Headed General, crying, "Sir, let us go! This must be a mistake!" Others stood there in shock, their eyes blank. For a moment, the scene was in chaos, filled with cries, shouts, and curses. Even the few monks and demons in the crowd wore expressions of fear and despair.

"Shut up!" the Bull-Headed General roared, his voice resonating like thunder. An immensely powerful pressure erupted, toppling them to the ground like a surging wave. The crowd and the beasts fell silent, not daring to breathe.

"Everyone, line up! Register and enter the city! Otherwise, I'll feed you to the dogs!" General Niutou's eyes widened in anger, his voice resounding like a bell. The three giant dogs echoed his words, growling deeply. They looked greedily at the people and beasts, drooling all over the floor, their sharp fangs gleaming coldly in the firelight, their expression intensely excited.

Well-trained soldiers immediately stepped forward to maintain order, their long whips cracking as they shouted at the men to line up at the city gates to register for entry. The recorder, with a serious expressionless face, quickly manipulated a virtual screen based on their accounts, his fingers darting. He constantly verified the truth, his eyes sharp, as if he could see through every lie.

If anyone concealed the truth, the soldiers, already well prepared, would rush forward like tigers, chaining them directly with heavy chains and dragging them mercilessly towards the city. Those being dragged away cried and wailed, struggling desperately, and begging for mercy at the top of their lungs, but the soldiers' faces were as cold as ice, and they paid no attention to their pleas.

This also made the people and the beasts behave themselves. The city gate was extremely wide, and they lined up in 18 long lines in an orderly manner, walking slowly inside like a long winding dragon.

As time slowly passed, the number of people and beasts gathered at the city gates dwindled. Yu Kai had considered taking this opportunity to turn back. With his current strength, his mecha could easily withstand the hail of arrows. But he worried that Niuniu had already entered the city. If she was already inside, how would he find her if he left rashly? With this in mind, he decided to suppress his impulse for the time being and investigate carefully.

As the last of the beasts registered their entry into the city, Yu Kai remained silent. Then, as if sensing something, the three enormous dogs suddenly roared fiercely towards his hiding place. The roar was deafening and terrifying. Hearing the dogs' warning, the entire army instantly felt like they were facing a formidable enemy, quickly surrounding him. The soldiers marched in unison, their armor clinking with a resounding sound, their weapons flashing coldly, their eyes filled with vigilance and hostility.

"Come out!" The Bull-Headed General, riding atop a three-headed giant dog, slowly approached, his aura growing stronger with each step. "I've been waiting for you for a long time!" His voice boomed like a dull thunderclap, piercing the air.

Yu Kai slowly released the enveloping spiritual energy, and his hidden figure gradually emerged. His dazzling mecha shone coldly in the firelight. Seeing Yu Kai in his mecha, countless soldiers subconsciously retreated, their eyes filled with wariness and fear.

General Niutou also looked at Yu Kai carefully with a sharp gaze, "Are you from the planet Asia?"

Yu Kai shook his head vigorously, "Where's my sister? Where did she go?"

"Not from Asia?" General Niutou's eyes instantly turned icy cold. Seeing this, the other soldiers breathed a sigh of relief and bravely stepped forward, their cold spears pointed at Yu Kai, instantly releasing murderous intent.

Yu Kai's mechanical sword instantly ripped from his body. With a humming sound, the blade flashed with a cold gleam. He was on full alert, his eyes wide. "Where's my sister?" His voice was filled with oppression. He ignored the troops and stared directly at the Bull Head General.

"Hmph!" General Niutou snorted, extremely dissatisfied with his tone. "You have violated the will of Heaven and altered fate, disrupting the order of both the Yin and Yang worlds. Why don't you surrender? I will bring you before Lord Yama to face punishment!"

"Hmph, what's wrong with me saving my sister?" Yu Kai swung his sword, and a sharp sword energy whistled out, carving a deep gully in the ground. "Tell me where my sister is, or I will personally tear down this damn hell gate!" His voice was like thunder.

"Capture him for me!" General Niutou spoke in a cold voice, which seemed to come from the abyss of the underworld, carrying endless chill.

"Kill!" Countless soldiers, spears in hand, roared in unison, charging towards Yu Kai like a tide. Their steps were steady and powerful, shaking the ground slightly with each step. The tips of their spears gleamed coldly in the firelight.

Yu Kai's eyes fixed, fearless. With a push of his foot, he moved towards them like a ghost. He swung the mechanical sword with impenetrable force, its shadows echoing thickly. With a flick of his wrist, the sword and spear collided instantly, the clang clang clang of weapons deafening, sparks flying like fireworks.

A soldier thrust his spear straight at Yu Kai's chest. Yu Kai dodged to the side, sweeping his sword across, severing the soldier's spear. Another soldier seized the opportunity to attack him from behind. Yu Kai, as if he had eyes on his back, spun around and kicked the attacker dozens of meters away.

Yu Kai's sword swung with the force of a hurricane, each swing accompanied by a whirring sound. He sometimes deflected the soldiers' spears, sometimes slashed through their armor, and wherever he struck, soldiers fell to the ground. But these soldiers, unflinching, attacked him again and again, their coordinated attacks coordinated with each other, some attacking first, others feinting, attempting to disrupt Yu Kai's rhythm.

Yu Kai shuttled through the crowd, slashing left and right with his mechanical sword, and sword energy crisscrossed, forcing the surrounding soldiers to retreat again and again.
