The strength of the high-level monster is indeed very good, diving down from a high altitude, the claws easily tore apart the skeleton knight's body, although the strength of the level 4 skeleton knight is not weak, but it is not the opponent of the high-level monster.

But fortunately, the skeleton knight's tacit cooperation and horse control skills are very good, and he can try to reduce the number of his own casualties when high-level monsters dive and attack.

"Goo!"

The screaming sound of the high-level monster was heard far away, and it swooped down again, its wings setting off a strong wind, blowing away the formation of the level 4 skeleton knight.

Countless low-level monsters swarmed up, and were driven by high-level monsters to use their bodies to resist the entangled level 4 skeleton knights, so that they could no longer form a strong combat power for group combat.

In the eyes of high-level monsters, the dispersed level 4 skeleton knights are just fat on the chopping board, to be slaughtered.

Every time the voice of the giant vulture echoed on the battlefield, it represented a group of level 4 skeleton knights who had been brutally murdered, their bodies torn apart, and their horses were not spared.

"It's over. ”

Chu Xinghan's expression turned pale, he knew very well that the Level 4 Skeleton Knight was the main fighting force against low-level monsters, if they were wiped out by the giant vultures, what else would the sea gathering place use to resist the tide of massive monsters?

The demise of the level 4 skeleton knight is only a matter of time, and when the time comes, the high-level monsters that are freed up can also turn around and deal with the ghost army, and if the sea gathering place loses the skeleton knights and the ghost army, it will only end up in the face of a massive tide of monsters and high-level monsters.

Chu Xinghan figured this out, his whole body was cold, and his heart was full of despair, and now he had no way at all.

Without the most sophisticated mecha troops, it is impossible to resist high-level monsters, so you can only wait for death.

It was at this time.

A mutation has occurred.

"Buzz!"

A strange trembling sound sounded, and gray-white beams of light suddenly burst out from the underground gathering place, and countless beams of light pierced the hillside where the sea gathering place was located.

The beam of light is staggering, covering the entire hillside, making the entrance to the hillside where the sea gathers look like a sea of gray.

Everyone in the command room and on the battlefield was shocked by the scene in front of them.

"What is this?"

"Is it a new weapon in the Gathering Place?"

Countless doubts and confusion filled everyone's hearts, and people couldn't help but look back, looking at the light on the hillside, including Chu Xinghan, no one knew what it was.

After a few breaths, all the gray beams converged into a thick gray-white beam that enveloped a level 4 skeleton soldier.

The level 4 skeleton soldier had long since retreated from the frontal battlefield to the rear and stood still, and anyone who noticed it moving had thought it was sucked in or tired.

It wasn't until this moment that people saw the level 4 skeleton that was shrouded in a huge gray beam of light into a ball of light, and at this time they understood, and Chu Xinghan also suddenly realized.

This is the means of An Baichen!

In the general command room, An Baichen's will at this time was completely focused on the body of this level 4 skeleton, he gave up the control and attention to the frontal battlefield, and paid close attention to the current situation of this level 4 skeleton, constantly adjusting the energy infusion frequency of the huge gray pillar of light.

This is indeed the means of An Baichen, or the means of the [Holy Grail of the Dead] artifact.

This is the real hole card of Amberson!

Although the [Grail of the Undead] is a gadget made by the previous Reaper, it is still powerful, at least for the undead creatures at this stage.

When An Baichen was at the place of the war, he had already taken out the [Holy Grail of the Dead] to accumulate the pure undead aura emitted by the soul fire that dissipated and destroyed after the defeat of the undead.

More than 80,000 level 2 undead have died, and there are many level 4 undead who have a terrifying undead aura after death.

Although it looked like it wasn't even a small glass full from the Holy Grail of the Undead, the amount of undead aura it could contain was terrifying, and it was even enough to create a level 5 special undead.

An Baichen didn't plan to use the power of the disposable artifact [Fair Domain] from the beginning, the [Fair Domain] was very powerful, but after all, it was a one-time consumable, and it was gone when it ran out.

In case he encounters a more powerful enemy in the future, it will be difficult for An Baichen, who lacks a strong hole card, to deal with it.

An Baichen felt that no matter how powerful the high-level monsters he encountered this time, it was impossible to surpass the strength level of the sixth-level undead, so instead of using the [Undead Holy Grail] in addition to resurrection, it was better to use the [Undead Holy Grail] to consume a large amount of undead breath collected from the battlefield to temporarily increase the level strength of one of the undead, and briefly break through the limit of the level of the undead world.

The undead breath in the [Necromantic Grail] is different from the undead breath in the undead world, and the undead aura in the [Necromantic Grail] can directly temporarily increase the health level of an undead and use it as undead energy that can be forcibly instilled.

However, there is also a disadvantage to this, after the pure undead aura accumulated in the Holy Grail of the Undead is consumed, the operation of resurrecting the undead can no longer be carried out.

Moreover, the undead creatures that have obtained a temporary increase in strength will also be completely dead because the soul fire carries energy far beyond their own tolerance limit, and after the artifact power fails, the blessed undead creatures will die completely.

That is, it is equivalent to the price of more than 80,000 undead and a level 4 skeleton in exchange for a temporary powerful undead creature.

An Baichen was a careful person, and he felt that instead of using the artifact that was consumed at one time, it was better to consume the pure undead aura of the more than 80,000 undead.

The undead breath can be earned again when it is gone, and the undead chalice is a permanent artifact that can be used for a lifetime, but if the one-time consumption artifact is gone, there will be a permanent missing hole card.

"The energy seems to be a little insufficient, and the speed of strength improvement is too slow. ”

An Baichen frowned, this was the first time he had used the Holy Grail of the Undead, and he didn't expect that it would be so troublesome to improve the strength of the undead, now that half a minute has passed, the strength improvement process of this level 4 skeleton has not yet ended.

Everything changes in the field in an instant, and no one knows what will happen in the next second.

"Brothers, we still have hope! Mr. An still wants hole cards, everyone continue to persevere!" Chu Xinghan shouted at the right time, he had just asked An Baichen and did not get a reply, he estimated that An Baichen must be very busy now.

Therefore, Chu Xinghan took the initiative to stand up to boost morale and let every soldier regain their spirits.

People must not despair, despair will lose the confidence to resist and make the situation worse.

The mutation of the battlefield was also observed by the high-level monsters, the giant vulture was originally abusing the Level 4 Skeleton Knights, but it suddenly sensed a gradually powerful aura power from behind it.

This aura is getting stronger and stronger, and although it is not comparable to its own life level, it has already made it feel a faint threat to life.

The giant vulture quickly shifted its target, and it flew into the sky and circled, a pair of huge pupils staring coldly at the level 4 skeleton soldiers behind the battlefield who were being transformed by a large number of pure undead breaths.

"Oh no, the Flying Demon King wants to interfere with Mr. An's plan!" Chu Xinghan looked up at the huge vulture, and couldn't help but sigh in his heart.

Although he didn't know what An Baichen was doing, it was obvious that this was a key means that could affect the outcome of the battle, and he must not let the Flying Demon King destroy it!

"Goo!"

The Flying Demon King, which looked like a giant vulture, erupted with a huge scream, shook its huge wings, and swooped down quickly, aiming directly at the level 4 skeleton that was being transformed!

It wants to kill the threat in the cradle in advance!

"Stop the Flying Demon King!"

Chu Xinghan reacted quickly at this moment, and he shouted decisively: "All the mecha squads and mutant soldiers are all out of battle! Stop the Flying Demon King!

"Yes!"

The operators of the mech team shouted in response, and the mutants from the team of soldiers stepped out, numbering in the hundreds.

Although they are all low-level mutants, they only have strong physical strength and no outstanding talent, but they have the determination to die!

Even if you use your life as a city wall, you have to block the Flying Demon King!

"Boom!"

The mech squad was activated, and all the small mechs and mutant soldiers rushed forward towards the Flying Demon King, trying to stop the Flying Demon King.

The Flying Demon King's pupils always reflected the appearance of the level 4 skeletons emitting gray light, and it didn't pay attention to the fact that these weak ants actually wanted to stop their actions.

Among the high-level monsters of human beings, most of them are ants, small and pitiful low-level creatures.

"Whew!"

The moment the Flying Demon King approached the ground, his huge wings carried a huge impact and slammed into it, and all the mutant soldiers and small mechs were blown out and smashed into the hillside, and the heavy mechs even killed a group of hapless adventurer members.

"Bang!"

Chu Xinghan felt the vibration from the internal organs of his body and the creaking sound of the back of the mecha, and he couldn't help but feel bitter in his heart.

A feeling of dizziness surrounded Chu Xinghan, he had long known the difference in strength between himself and the high-level demons, but he didn't expect that the gap was so big that they couldn't even stop the high-level demons.

The only heavy mecha in the gathering place that could stop the high-level monsters had been destroyed, and the few large mechs had run out of energy.

The energy of the small mecha that rushed up had actually been exhausted a long time ago, all because the operator was a mutant with strong physical strength and strength, and he was forced to use his body to control the mecha in order to continue fighting.

But it turns out that even a small mecha at the peak of its state is no match for high-level monsters, and small mechs that are depleted of energy are even more fragile, and they can't even get close to high-level monsters.

"It's a pity, if there are more new mechs and more powerful mutants in the sea gathering place, why should we be reduced to this point!"

Chu Xinghan looked anxiously at the location of the level 4 skeleton, he was now suffering from multiple fractures all over his body, unable to move.

Not dying in front of high-level monsters is already a proof of strength, and Chu Xinghan is still worried about the fate of level 4 skeletons at this moment.

Chu Xinghan shouted hoarsely in the headset with his last strength: "An Baichen, let the undead legion fight back, we can't let your plan be blocked!"

"No, I don't. ”

An Baichen's faint voice sounded from the mecha headset, and he took the time to reply, he saw Chu Xinghan's fearless behavior just now.

This is really a fool, knowing that he can't stand up.

"Whew!"

The Flying Demon King was extremely fast, and after fanning the mutants and mechas, it once again increased the distance, flying over the first battle line area, and floating in the air above the level 4 skeletons.

"Huh!"

The Flying Demon King's claws shimmered with an eerie chill in the afternoon sun, and they gripped at the head of the level 4 skeleton fiercely.

Now, there is no one who can stop it.
