When Yang Yu walked out of the main hall, the originally silent valley was already full of murderous sounds at this time.

As far as the eye can see, there is a black pressure between the mountains and mountains, not to mention that there are five or six thousand earth demons.

The appearance of the Demon Sect is something that has only recently exploded.

Therefore, although the Blood Knife Ancestor already knew that the Demon Sect army was hidden in the spirit vein, because they were hiding in the depths of the ground, they had not yet thought of a way to deal with it for a while.

Now that the night is suddenly coming, the Blood Knife Gate is also in a hurry.

Originally, the sect was built on a cliff, and as long as it guarded the passes, it was difficult for ordinary armies to attack it.

But the earth demons are all equivalent to the cultivation of the Grandmaster realm, and their physical bodies are very strong, and ordinary bows and arrows can't hurt them at all.

And the dozens of Heavenly Demons who led the team have even reached the level of Super Grandmaster in cultivation.

They spread their wings and flew high, and a single dive took away a wave of human heads.

Such a dimensionality reduction blow, coupled with the fact that they already live underground, have long been accustomed to the darkness.

Fighting at night, the Terrans are at a disadvantage.

So after a wave of charges, the pass was immediately lost.

Now they can't be stopped by the city walls alone.

Even if the disciples of the Blood Sword Sect tried their best, they would soon fall.

And the most terrifying point is that some disciples suddenly fell into confusion, and then slashed their weapons at their own people, obviously bewitched by the demons.

As a result, everyone doesn't know when the comrades around them will suddenly become enemies, so the team's combat power plummets.

Yang Yu looked up at the sky and found that the five elders of the Blood Knife had already fought with the five demons.

Both sides are half-step scattered immortal cultivators, and the fight is difficult to solve.

But after a few glances, he knew that the five elders did not have air superiority, and there were faint signs of defeat.

Because the demon man has wings, he can change his flight trajectory in the air at any time.

While the five elders are fighting, they also have to consume their true qi for stepping into the air, so they only have passive defense.

After the Blood Knife Ancestor chased him out, he also frowned when he saw this scene.

was about to make a move, but Yang Yu grabbed him.

"Twelve demon generals, the remaining nine are all out of the nest, and there are even stronger demon sect masters behind, don't rush to make a move first, be careful of the ambush."

After sweeping around, Yang Yu immediately made a judgment and knew that tonight's crisis was much more complicated than he imagined.

"What's the solution, tell me quickly." Blood Knife Ancestor said urgently.

"I'll open a defensive formation and let everyone hide in and talk about it, otherwise I won't be able to do anything if the enemy and us are mixed together."

If you want the Blood Knife Ancestor to help him solve the problem, you naturally have to help the Blood Knife Sect solve tonight's crisis first.

But the two sides were in a scuffle, and his methods were useless.

Therefore, at the first time, the two sides must be distanced so as not to accidentally injure their own people.

With that, Yang Yu immediately took out a stack of array disks, and the humming formation was fully opened.

One, two, three, four......!

Sixty-four seven-star formations are superimposed, which can resist the earth demons of the Enlightenment Realm;

One hundred and twenty-eight formations are superimposed, which can resist the Heavenly Demon Demons of the Manifestation Realm;

And the two hundred and fifty-six formations are superimposed, and they can resist the demons in the psychic realm;

But this time, Yang Yu decided to empty all the inventory and directly open a super giant array with five hundred and twelve formations superimposed!

It's just that to open such a huge array, even if you open a formation disk in one second, it will take ten minutes.

Seeing that the formations were rapidly superimposed, and they were able to achieve a perfect bite, the Blood Knife Ancestor was also surprised.

Maybe he knew that Yang Yu's formation was powerful, and the other party had already prepared.

Just as he opened the formation, a black shadow suddenly rushed towards the formation from the darkness with lightning speed, trying to stop his operation!

Yang Yu didn't raise his head, but just stretched out his hand and waved, and the Demon Devourer who had been taken into slavery immediately appeared beside him.

Bang!

The demon man was caught off guard, and was repelled by the devouring demon's palm, and smashed a large pit directly on the ground, and the dust was flying.

"Shenma situation?!"

Seeing the demons fighting the demons, the Blood Knife Ancestors were stunned.

"The slave of the Demon Sect I received, don't make a fuss."

The moment he replied, there was already a sound of sharp arrows breaking through the air overhead.

"Don't be stunned, help me block it!"

Seeing this, Yang Yu immediately shouted.

The Blood Knife Ancestor instantly came back to his senses, and quickly jumped up and greeted the person who rushed towards the sky.

Rumble!

As soon as the two sides touched and separated, the shock wave between the palms of each other actually surged in all directions, almost destroying the dozens of arrays that had been opened with great difficulty.

Bang!

The Blood Knife Ancestor landed on the ground, and his face had become very ugly.

The people of the Demon Sect who can take him from scattering immortals and cultivating them as a palm are definitely higher than the level of the evil demons.

I didn't expect a sneak attack tonight, and the other party even ran out of such a monster.

And the moment he landed, another sharp murderous aura had fallen from the sky.

In the flash of light, the Blood Knife Ancestor had no time to regain his energy, and could only watch the murderous aura fall.

And at this critical moment, a young girl suddenly flashed and greeted her in an instant.

But this time, Ami Amami was also knocked to the ground and fought an equal with the other party.

Yang Yu chuckled in his heart, and suddenly felt bad.

The combat power of Ami Tiangong has always been an unknown.

Now she is just a draw with the other party, proving her strength, and probably the strength of the immortals.

After scanning just now, I knew that these Demon Sect masters hidden in the shadows were the four protectors of the Demon King's side.

They are called demon cultivators, and their combat power is comparable to that of scattered immortals.

Moreover, the other party poured out tonight, and when he saw that he opened the formation, he swarmed up, proving that he was the main target of the Demon Sect.

In this way, compared with the strength of the two sides, their own side is obviously at a disadvantage.

The whole process, from the attack of the demons, to the sneak attack of the two demon cultivators in turn, is just a moment of lightning.

In a flash of thought, the third murderous aura had arrived.

"Serial ambush?!"

Yang Yu's pupils shrank.

It seems that the other party has calculated the number of people on his side, and is ready to break his super giant array in one go, so as not to let him succeed.

Now that the Blood Knife Ancestor and Tiangong Ami had just fought each other, it was too late to strike again.

"Ma Dan, I didn't expect the hole cards to be taken out here, it's really vomiting blood!"

Seeing that this blow was about to fall, Yang Yu cursed secretly, and an old man had already flashed out beside him.

The moment the old man appeared, although he looked confused, he immediately sensed the murderous aura above his head.

"Help me block it!"

Hearing the simple and clear command, the old man shouted violently and slapped it with one palm.

"Old monster, why are you here?!"

Seeing the old man who suddenly appeared, the corners of the Blood Knife Ancestor's mouth twitched.

As soon as the words fell, I only heard a bang!

The third murderous aura was instantly dispersed by the old man.

Fortunately, although the formation was affected by the shock wave, it did not collapse.

However, at this moment, the fourth shockwave has arrived!

The protectors of the four major demon sects actually chose to attack in a row.

It can be seen that they have understood that if they want to kill Yang Yu, they must be vigorous and cannot give him a chance to breathe.
