At this moment, City Lord Qin only felt a cold force coming towards him, and a thin layer of frost condensed on the sword, causing his offensive to stagnate.

But he was concerned about his son's safety, so he gritted his teeth, took a deep breath, shouted loudly, and the long sword in his hand shone brightly. He slashed at the fog with all his might, trying to break through the obstacle.

Seeing this, a hint of impatience flashed in the eyes of the evil skull old man. His dry fingers bent slightly and he muttered to himself.

In an instant, several black tentacles as solid as substance stretched out from the mist, wrapping around City Lord Qin with bared fangs and claws.

These tentacles are covered with strange runes and emit a disgusting stench.

Young Master Qin was extremely anxious watching from the side. He struggled desperately to get up and help, but found that his legs were weak and he had no strength at all.

"Dad, stop! Leave me alone!" he roared, his voice hoarse.

City Lord Qin dodged the attack of the black tentacles. He looked a little disheveled and his clothes had been torn in many places.

But his eyes were determined, and he didn't flinch. He saw an opening and pounced on the old man again, sword pointed at the throat of the evil skull: "If you don't save my son today, how can I, Qin, live in this world with dignity!"

The evil skeleton old man snorted coldly, his body suddenly stood up, and the bones all over his body creaked, as if trying to break free from the constraints of flesh and blood.

He quickly formed seals with his hands, and a blood-red light gathered in his palms. He slammed it down towards City Lord Qin, shouting, "Since that's the case, then I'll grant your wish."

At this time, the second and third young masters Qin opened their eyes wide, their faces full of panic, and shouted at the top of their voices: "Dad, be careful!" The sound echoed in this empty place, revealing endless worry.

The two brothers were extremely anxious and their feet unconsciously rushed forward a few steps, but were fixed in place by an invisible pressure. They could only watch their father running towards danger.

At this critical moment, a white shadow seemed to fall from the sky and flashed in front of City Lord Qin at lightning speed. It was the ancestor Bai Fu.

The long sword in Bai Fu's hand turned into countless swords in an instant. The sword bodies flashed with cold light, like starlight, whistling towards the red light of the evil skull old man.

These sword shadows were so fast that only afterimages were left, like a school of silver fish flying around, weaving an impenetrable sword net in an instant, blocking the evil skeleton old man's retreat.

Seeing this, the evil skull old man's face changed slightly, and the ball of red light that was about to hit City Lord Qin suddenly shrank and then expanded.

It turned into a blood mist, in which a hideous ghost face emerged, emitting bursts of roars.

He quickly changed the magic spells with his hands, controlling the blood mist to resist Bai Fu's sword rain.

Every collision produced a loud noise like the clanging of metal, sparks flew, and light shone brightly, causing the surrounding ground to crack and rocks to fly.

City Lord Qin took the opportunity to retreat to his sons' side. He was breathing heavily, gripping his sword tightly, and watching the battle situation vigilantly.

Young Master Qin's heart was filled with regret and self-blame at this moment. If he had not caused so many troubles, his father would not have fallen into such danger.

The second and third young masters of Qin supported their father on the left and right, watching the situation on the field without blinking.

He secretly clenched his fists, regretting that he was young and weak and could not rush forward to help.

Bai Fu's expression was stern, and the sword techniques in his hands kept changing, driving the sword shadows forward layer by layer, pressing the evil skeleton old man step by step.

"If you don't retreat today, don't blame me for being ruthless with my sword."

Xie Ku sneered, "If you're willing to hand over your granddaughter, I'll retreat."

After he finished speaking, the blood mist surging around him gradually turned black, like spilled ink, sticky and emitting a foul smell.

This strange black fog seemed to have life, slowly but steadily corroding Bai Fu's sword. With a sizzling sound, the sword shadows dissipated one after another.

Baili Shuijing shouted from below: "Brother, be careful!"

His eyes were solemn, and he quickly formed seals with his hands. As the seals were completed, a round red sun seemed to be wrapped in the true fire of heaven and earth, and it moved towards the black fog with great momentum.

The two collided with a loud bang, the loud noise hurt everyone's eardrums, and the powerful impact made both sides stagger back a few steps.

Bai Fu looked closely and saw that his sword had been eaten away by the black mist, leaving only a little black ash, floating in the air, and finally fell slowly to the ground powerlessly.

A trace of regret flashed across Bai Fu's eyes. This sword had been with him for many years and had gone through countless storms, but today it suffered such a disaster.

But the situation was too critical at the moment and he couldn't afford to be too sad. He took a deep breath and retreated to the square.

The evil old man laughed heartily in the air. His laughter was so sharp and piercing that it seemed to cut through the sky. "I never thought that after a thousand years, you righteous sects would only be able to do this much."

Hurry and hand over your granddaughter! Otherwise, today will be the day of your destruction.

The eldest brother hurried over, his face full of worry: "Grandpa, how are you?"

Bai Fu shook his head slightly and said, "Grandpa is fine. It's just that I don't know what kind of skills this evil cultivator practiced that he was able to corrode Grandpa's sword."

Before he finished speaking, two figures appeared in the sky.

Xuan Yunzi saw the figures of Baili Shuijing and Bai Fu in the square, then he quickly flew down and stepped forward to greet them: "Old friend Bai Fu, Sect Master Baili, it's been a long time since we last met. What's going on?"

He was dressed in a grey robe, holding a whisk, with a clear face and a look of concern. Master Xuanfeng followed closely behind him.

Baili Shuijing and Bai Fu saw the person coming and greeted him at the same time.

Baili Shuijing bowed and smiled, "Master Xuanyunzi, you've arrived at the perfect time! The two of us are being tormented by this evil old man."

Bai Fu also clasped his fists slightly and nodded in greeting: "Long time no see, Taoist priest.

This evil old man used all means to take my granddaughter away. Even my sword was broken. It was really hard for me to resist.

After hearing what Patriarch Bai Fu said, the two of them felt a little confused.

Seeing this, the eldest brother hurried forward and explained the whole story.

After hearing this, Xuan Yunzi and Xuan Feng Zhenren looked at each other with disbelief in their eyes.

He quickly said, "My junior brother and I wanted to visit the owner of Dongling Pavilion, but I didn't expect it would be your sister.

Xuan Yunzi then looked towards the Evil Skull Elder in the air with a determined gaze, and said, "Young Master has done us a favor. If you want to see him, you have to go through me."

After saying this, he waved the whisk in his hand, and the dust strands stood upright, gleaming with light, as if he was ready for battle.

The evil skull old man looked at the people below, snorted coldly and said: "Hand over the little girl quickly, or you will all die."

As he spoke, the terrifying black fog around him rolled and surged, sweeping towards the square like a black raging tide.

Seeing this, everyone hurriedly used various means to stop it.

Master Xuanfeng quickly drew out the long sword from behind him, and the sword rang like a dragon's roar. He turned his body, causing the sword energy to fly horizontally, and built a sword curtain in front of him, trying to stop the black fog.

Although Bai Fu no longer had his sword, he quickly formed seals with his hands, and white light patterns appeared on his palms, pushing towards the black fog.

Baili Shuijing and the Qin family father and son also joined the battle.

For a moment, the square was filled with bright light and powerful energy, which collided violently with the overwhelming black fog, and the roar was endless.
