The new mission of the CEO of the Miraculous Doctor after traveling through time

The sky in the north city was originally as blue as a gemstone, clear and bright, but today, an extremely oppressive atmosphere rushed in from afar, like a dark cloud covering the sun, but even more gloomy and terrifying than that. In an instant, the sky darkened suddenly, and the wind howled through the streets and alleys, with flying sand and rocks. The people fled home in fear, and the closed doors and windows could not hide the chill rising from the bottom of their hearts.

The mysterious man appeared, hanging over the North City, like a demon from the Nine Nether Purgatory. He was tall and burly, wearing a black robe that fluttered, and black magic light surged around him, like a black flame dancing wantonly. Wherever the magic light went, the space seemed to be burned and distorted. The deterrent power of the magic light spread like ripples, and the people on the ground suddenly felt a splitting headache. They covered their heads in pain, and wailing rose and fell, echoing throughout the North City.

"This devil finally couldn't hold back and showed up!" Nie Bo's eyes flashed coldly, and he tapped the ground with his toes. His figure shot straight into the sky like an arrow from a bow, his clothes fluttering in the wind. The long sword in his hand was instantly unsheathed, and the sound of the sword was crisp and exciting, just like the roar of a tiger or a dragon. The sword body flashed with cold light, as if it could cut through the sky. A pure immortal power lingered on it, competing with the surrounding magic light, stirring up circles of energy ripples visible to the naked eye.

Ye Chen was also unwilling to fall behind. He took a deep breath, and the spiritual power in his body surged and circulated. A soft but tough halo appeared around him. He tapped his feet lightly, and after a few takeoffs, he flew into the sky and stood side by side with Nie Bo. His eyes were cold, and he locked onto the mysterious man. He opened the folding fan in his hand with a "swish", and the spiritual patterns on the fan flickered. Although he looked like a weak scholar, he exuded an aura that should not be underestimated.

When the mysterious man saw the two people flying up, he let out a piercing and unpleasant laugh. The laugh was like a sharp blade that materialized, echoing in the air and making people's eardrums hurt. He suddenly stretched out his hands, and the black magic light was like two huge pythons, pouncing towards Nie Bo and Ye Chen with bared fangs and claws. Wherever he passed, the air was torn apart, making a "sizzling" sound.

Nie Bo snorted coldly, raised his sword and rushed forward, his sword was as powerful as a rainbow, sometimes stabbing, sometimes slashing, each sword accurately cut the vital points of the magic light python. The magic light python was hit by the sword, and it roared, and its black scales flew and scattered, but it reorganized in an instant, and its attack became more fierce. Ye Chen was agile, waving the folding fan in his hand, fanning out a series of sharp wind blades, which whistled and cut the magic light, complementing Nie Bo's sword moves.

The wind howled over the North City, and the black magic light emanating from the mysterious man rolled like an inky cloud, dyeing the day into a dark night. The pressure brought by the magic light was like an invisible hammer, smashing the ground. The people huddled on the ground in pain, their hands tightly covering their heads, and wailing was endless.

Nie Bo took the lead. He rushed towards the mysterious man with a nimble figure like a hawk swooping down on its prey. The long sword in his hand hummed and slashed out like a dragon. A stream of sword energy slashed at the magic light. Wherever the sword energy passed, the air was split open, making a "hissing" sound. At the same time, Ye Chen was not far behind. He tapped his toes lightly, his clothes fluttering, and he flashed to Nie Bo's side in an instant. The folding fan in his hand "swished" and the spiritual patterns on the fan shone. As he turned his wrist, several sharp wind blades whizzed out in a fan shape, cutting the black magic light.

Seeing this, the mysterious man let out a wild and piercing laugh, which shook the clouds and the sound waves were like materialized sharp blades surging in the air. He waved his hands, and the magic light seemed to have life, instantly condensing into two huge black pythons, with their scales flashing coldly, their mouths wide open, spitting out black tongues, and swiftly pounced towards Nie Bo and Ye Chen.

Nie Bo's eyes were firm, and he did not retreat but advanced, swinging his sword straight at the python. His sword skills were sharp and varied, picking, wiping, poking, and stabbing, and each move accurately attacked the python's vital point. The sword collided with the magic python, sparks flew, and black scales flew everywhere, but the magic python recovered in an instant, and the attack became more and more fierce. Nie Bo gritted his teeth, and the immortal power continued to pour into the sword body. Every time he resisted, his palms were numb and his arms were sore, but he relied on his tenacious will to break through a world of flashing sword shadows in the magic light.

Ye Chen's figure was agile, like a ghost shuttling between the magic lights. When he opened and closed the folding fan in his hand, the wind blades crisscrossed and matched Nie Bo's sword moves. Sometimes he used wind blades to restrain the action of the magic python, creating a good opportunity for Nie Bo to attack; sometimes he fanned out a soft wind to help Nie Bo remove the impact of the magic python. But as time went on, he gradually felt exhausted, his spiritual power was consumed greatly, beads of sweat rolled down his forehead, and his breathing became rapid.

The mysterious man continued to attack, and the magic light became more violent. He seemed to be deliberately playing tricks on the two of them, controlling the magic python to move left and right, up and down, making it impossible for Nie Bo and Ye Chen to defend themselves. The magic python swept its long tail, and the strong wind it brought knocked Nie Bo to the side. Nie Bo forced himself to stabilize his body in the air, and blood flowed from the corner of his mouth. Seeing this, Ye Chen hurriedly flashed in front of Nie Bo, using his fan as a shield to block the magic python's subsequent attacks, but he was also shocked by the magic light and retreated several steps, his face pale.

The two looked at each other, and saw the unyielding and resoluteness in each other's eyes. Nie Bo took a deep breath, and clenched the long sword with both hands. The sword body shone brightly. He compressed all his immortal power to the extreme, and shouted: "Demon Breaking Sword Technique!" In an instant, a dazzling white sword energy that seemed to be able to create the world gushed out from the tip of the sword. The sword energy was surrounded by flashing electric light, and the power contained in it made the space tremble.

Ye Chen also used up all his remaining spiritual power and quickly formed seals behind him. Ancient and mysterious runes appeared in the air and merged into Nie Bo's sword energy. The already powerful sword energy became even more powerful under the blessing of the runes, like a roar from a god, rushing straight towards the mysterious man.

The mysterious man felt threatened, and for the first time a solemn look appeared on his face. He crossed his hands rapidly in front of his chest, and magic light gathered madly, condensing into a black shield in front of him that was more than ten feet thick. Magic patterns surged on the surface of the shield, emitting a strange aura.

"Boom!" The sword energy and the shield collided with a loud bang. In an instant, the entire sky above the North City was shrouded in dazzling light, so bright that people could not open their eyes. Then there was a deafening explosion. The powerful impact spread in a circle, and countless houses below were overturned. The people were even more staggered under this impact. Nie Bo and Ye Chen were like kites with broken strings. They were shaken and flew backwards for dozens of feet. They fell heavily to the ground, spitting blood and ragged clothes. The mysterious man also got a bad result. He staggered, his black robe was torn, and the magic light was dim and sluggish, like a candle in the wind.

"Hmph, let's stop for now!" The mysterious man snorted coldly, unwilling but afraid of the two people's desperate counterattack, and turned into a black stream of light and disappeared into the sky in an instant. The sky above North City was filled with smoke. Nie Bo and Ye Chen, who survived the disaster, looked at the sky with worry and determination in their eyes. They knew that this duel was just the beginning, and a bigger crisis was still to come...

For a moment, the sky above North City was bright, and the immortal power and magic power collided and blended with each other, erupting with a deafening roar. Under the bright light, Nie Bo and Ye Chen had resolute faces. They gritted their teeth and secretly pondered the origin and purpose of this mysterious man. This person's magic power was unfathomable, and he was definitely not an ordinary magic cultivator. Judging from the bloody storm that he caused when he appeared in North City, there might be a more shocking conspiracy behind him.

The mysterious man's attack continued unabated, the magic light continued to surge, and Nie Bo and Ye Chen gradually felt the pressure like a mountain. Nie Bo's sword moves began to slow down, his arms trembled slightly, and every time he resisted the impact of the magic light, his knuckles were numb; Ye Chen was also panting, the power of the wind blade he fanned out was slightly reduced, and beads of sweat rolled down his forehead, dripping into the air and instantly turning into wisps of water vapor.

However, the two of them looked at each other with firm eyes, and a tacit understanding was born. Nie Bo shouted loudly, and all his immortal power gathered madly on the tip of the sword. A dazzling white sword energy gushed out, like a falling star, piercing straight at the mysterious man. Ye Chen used all his spiritual power to quickly form seals behind Nie Bo. Runes emerged one after another, blending into the white sword energy, doubling its power.

Seeing this, the mysterious man's face changed slightly, and he quickly crossed his hands in front of his chest, and the magic light condensed into a thick shield in front of him. The sword energy slammed into the shield, making a loud noise that shook the earth. For a moment, the light was so dazzling that people couldn't open their eyes. The powerful impact caused Nie Bo and Ye Chen to fly back several feet, with blood flowing from the corners of their mouths. The mysterious man also shook, his black robe was torn in several places, and the magic light dimmed a little.

"Hmph, I'll spare you today. North City will be mine sooner or later!" The mysterious man said harshly, and turned into a stream of black light, instantly disappearing into the sky, leaving behind only the devastated sky of North City, the exhausted Nie Bo, Ye Chen, and the suffering people. When the smoke and dust cleared, Nie Bo and Ye Chen smiled bitterly at each other, knowing that this war was just the beginning, and the road ahead would be more difficult and dangerous than they could imagine... Then, the two slowly descended, comforted the frightened people, and began to rebuild North City, secretly accumulating strength in their hearts to prepare for the next more violent attack from the mysterious man. North City, under the brief calm, undercurrents surged, and a bigger storm was quietly brewing.
