"This ......"

Everyone looked at the great changes behind them, and they all looked at each other.

Before, they still imagined that after defeating this demon venerable, they would be able to defend the front city gate.

But now, that illusion has been shattered.

The corpses on the opposite side were more than ten times their number, and now that the city wall had collapsed into a large opening, it was impossible to hold it no matter what.

"What to do!?"

Suddenly, everyone present felt extremely helpless.

And at this moment, I saw the Lord of Ning Mansion raise his arms and exclaim.

"Everyone, first knock this demon venerable back with all your might. After surviving this time, the adults in the headquarters will rush to the rescue!"

Although some people did not believe it, there was no better way. Besides, at least just now, the Lord of the Ning Mansion had repelled that demon venerable, which also gave them some confidence.

Therefore, seeing that the Lord of the Ning Mansion had already taken the lead, the surrounding martial artists did not dare to slack off, and each of them performed their stunts and attacked the Demon Venerable of the Knocking Mountain.

"Storm and Clouds Break!"

"Scorching Sun!"

"Thunder!"

For a while, all kinds of detached true qi suddenly came out, and the target was directly aimed at the vital points around the body of the Demon Venerable of the Knocking Mountain. And the one who rushed to the front was the Qingfeng Slash that the Lord of Ning Mansion used with the help of the spirit weapon.

However, the Knocking Mountain Demon Venerable did not panic in the slightest, but instead looked calm, as if he had already made preparations.

The previous earth-shattering seemed to consume a lot of his physical strength, so this time, he didn't perform this powerful move again, but took a deep breath.

The next moment, I saw him lean forward sharply and open his bloody mouth.

"Mountains and tsunamis!"

In an instant, from the mouth of the Knocking Mountain Demon Venerable, a strong sound wave visible to the naked eye erupted, and it slammed into everyone's attack.

Rumble!

As soon as the two sides came into contact, they saw that the true qi of each martial artist was separated from the body, like paper paste, and it was instantly shattered.

Not only that, but the sound wave continued unabated, and it was like a roaring attack by everyone.

"It's not good, everyone retreat!"

In the crowd, I don't know who shouted.

However, such a reminder was too late, and before everyone could move a few steps, the sound wave was already close to the front.

Boom!

Everyone suddenly felt as if they had been attacked by a heavy hammer, and their bodies were unstable on their feet, and they immediately flew upside down.

At the same time, their protective true qi was also shattered, and they were directly hit by that sound wave.

Burst!

There were many martial artists who couldn't withstand this huge impact, and their throats were sweet, and they directly spurted out a large mouthful of blood. Then they fell to the ground. For a while, I couldn't stand up at all.

In just one round, more than half of the more than ten martial artists who besieged the Demon Venerable had already been lost.

The remaining ones are also almost crumbling. And standing at the forefront is the Ning Mansion Lord who has cultivated to the highest level.

At this moment, seeing that the martial artist with the highest cultivation had not fallen, the corner of the mouth of the Mountain Demon Venerable was raised, and he couldn't help laughing.

"Oh!?You're a good guy, rushing in front of you and not being knocked down by my sonic waves, it's really a bit beyond my imagination!"

"There's so much more you didn't expect!"

The Lord of the Ning Mansion slowly raised his head and said fiercely.

Immediately, he withdrew the three-foot Qingfeng Spirit Weapon that was protecting his chest and pointed at the Knocking Mountain Demon Venerable.

"How bold and wicked you dare to hurt so many of my brethren. Today, I'll let you be the sword of this Qingfeng Sword......"

However, before the Lord of Ning Mansion finished speaking, he only heard a "crackling", and the Qingfeng Sword broke in the middle.

"Ha-ha-ha!"

Seeing this, the Demon Venerable of the Knocking Mountain immediately burst into laughter, and his mouth also mocked sharply: "I am really laughing to death, are you going to take that half of a toothpick to poke me to death?

At this time, the Lord of Ning Mansion was shocked, as if he hadn't expected it at all.

However, this spiritual weapon of his was already broken, and he had used it to resist the sonic impact of the Knocking Mountain Demon Venerable before, and it was already very good that he could hold on until now.

It's just that seeing that he died before he left the school, a lot of chagrin still appeared in the eyes of the Ning Mansion Lord.

At this time, the Demon Venerable of Knocking Mountain was even more smiling and could barely straighten his waist.

After all, the spirit weapon that could pose a slight threat to him was still broken, and the rest of the weapon might not even be able to exert half of its power. That is, on the spot, there is nothing left to threaten him!

However, at this moment, a hint of alertness suddenly appeared in his heart.

The next moment, I saw a figure suddenly flying out of the head of the Demon Venerable of the Knocking Mountain, which was none other than Huo Xiu, who had been dormant for a long time.

At this time, I saw Huo Xiu holding a blood-red true qi blade four or five zhang long with both hands, and slashed at the back of the head of the Mountain Demon Venerable.

"One thought is eternal!"

In an instant, the battle knife in Huo Xiu's palm shone brightly, and it was about to slash at the head of the Knocking Mountain Demon Venerable.

Now, it's too late to take on it. The Demon Venerable of the Knocking Mountain was shocked, so he simply gave up blocking it, and directly used the demon qi shield and strong body to resist this move.

Tong!

Only a loud bang was heard, and the Demon Venerable who knocked on the mountain suddenly felt dizzy. Although Huo Xiu's slash didn't completely break through his defenses, just this violent impact made him almost unbearable.

At this time, the True Qi blade in Huo Xiu's palm also broke because he couldn't withstand this huge impact.

The Demon Venerable of the Knocking Mountain endured a severe headache, and the corners of his eyes twitched, but he still found this situation, and he couldn't help but be happy.

He suffered such a big loss, and he hated the sneak attacker very much. At this time, seeing that the opponent's offensive had been broken, he had to take the opportunity to counterattack.

The next moment, I saw the knocking mountain demon Venerable turn his head violently, and with a puff of cheeks, he was about to unleash the mountain roar tsunami at Huo Xiu again.

But at this moment, he saw that Huo Xiu was not in a hurry and had already dealt with it. In his palm, a strong golden light suddenly erupted, and it shook so much that the Demon Venerable couldn't open his eyes.

However, the attack of the Knocking Mountain Demon Venerable was already on the verge and had to be launched. He simply closed his eyes and directly issued his long-planned trick.

"Mountains and tsunamis!"

"Vajra Mahamudra!"

Although Huo Xiu's combat skills are strong, the other party is a demon venerable after all, and his strength far surpasses him.

Therefore, as soon as his Vajra Mahamudra came into contact with it, it immediately disintegrated and ceased to exist.

However, after all, the Knocking Mountain Demon Venerable didn't aim at the last moment, but just relied on the feeling that Huo Xiu launched a blow, which was naturally a deviation, and the power was not as strong as before.

Even so, after Huo Xiu was hit by this blow, he still fell straight down like a bird with broken wings.
