The Blood Oath is the angel's last hole card and killer weapon!

This is the power that only angels with more than four wings can use, you know, in order to maintain the purity of their souls, angels are creatures who will generally try to keep their hearts indifferent to reduce exposure to too many negative emotions, even if it is fighting and killing, they must also shout the slogan of justice, in order to strengthen their will and not let themselves fall because of negative forces.

But the Blood Oath is an exception, angels are also creatures of free will, they also have their own brothers and compatriots, and they also have their own cherished people, so they can also have a sense of revenge because of anger.

The Blood Oath is one such power, which can transform the angels into blood angels through the wrath and revenge of the angels, giving them more power to complete their revenge.

This is the origin of the vengeful angel in human legends......

But the Blood Angel transformed from the Blood Oath is also depraved in the eyes of the orthodox angels, which is a sign of being blinded by anger and revenge, but compared to the real fallen angels, the blood angels are still self-conscious and will not stand on the opposite side of the angels.

Therefore, if you want to transform into a blood angel through the blood oath, the price is huge, the moment the transformation is completed, they are equivalent to being banished, and they are never allowed to return to heaven, and if the revenge in the oath is completed, after killing the object of revenge, the blood angel will gradually die.

However, the few four-winged angels present did not plan to think more, now the battle situation on the heavenly side was already in an extremely disadvantageous state, even if they did not make the blood oath, staying in the human realm would not be able to change this situation, it was better to incarnate as a blood angel and kill one or two demon lords on the demon side.

For hundreds of millions of years, the hatred between angels and demons in this world has long been so thick that it cannot be resolved, especially after the start of this Doomsday Judgment battle, the angels have also been affected and began to try some desperate moves......

If you don't succeed, you will become benevolent.

After deciding on the ground, the angels' ritual was quickly prepared, and they carved a huge golden magic array on the spot, and thousands of low-level angel soldiers knelt down on one knee on the periphery of the magic array in unison, inserting the weapons in their hands into the ground, and in the magic array, six four-winged angels faced each other in a circle, and also knelt on one knee.

With their heads down, one of their hands on their chests, they began to chant in a low voice as they poured magic into the magic circle for synergy.

Gradually, the magic array emitted a dazzling light, enveloping the six four-winged angels in it, and as time passed, the color of the light gradually changed, from a golden glow to a blood-red color, and the four-winged angels who were enveloped in it also let out a painful roar at the same time.

However, they forcibly endured it and persevered until the completion of the ceremony.

When the light of the magic array gradually dissipated, what appeared in the eyes of the angel soldiers were six kneeling blood angels!

Their appearance has not changed much, but the wings gathered behind them have turned from the original white to a blood-like bright red, and even the armor and angel sword on their bodies have been dyed with a blood-red halo, and at the same time, the surging magical aura is also blooming wantonly on them.

The Blood Oath did not promote them, but it could stimulate their potential and allow them to temporarily increase their strength, these six four-winged angels, originally five of them were energy angels, and one was a lower level of power angels, but after completing the blood contract, they all became the existence of the main angel level.

It can be said that none of them are weaker than Yuriel in their heyday......

In this way, the six main angels of them combined, even if they really met the demon lord, they would have the strength to fight, plus a large number of low-level angel soldiers to cooperate with them, this is a combat force that cannot be ignored.

Most importantly, the Blood Oath was able to identify the person they had prayed for revenge, and the object of their previous wish for revenge was the murderer of Abaddon and Juliel!

In the case of the former, of course, it is the demon lord Strieg, but the latter ...... But it's Roy!

The angels all miscalculated, they thought that it was a demon lord who killed Yuriel, but they didn't expect that it was Roy, the superior demon, who really killed Yuriel, Yuriel was injured at the time, and her condition was not good, Roy and Juliel used the expulsion spell on Frost Sorrow to suppress Yuriel's magic, so they killed her smoothly, otherwise, if it was really one-on-one, Roy still lacked a lot of strength against Yuriel in a complete state.

But this kind of thing is like fighting, in the case of life and death, who cares if you are in your heyday? Roy just needs to do everything he can to kill Yuriel.

However, after killing Uriel, an important person in heaven, the follow-up impact still came, and now Roy never thought that there would be a group of four-winged angels who chose to incarnate as blood angels in order to avenge Uriel, and if Roy was once encountered by them, this group of blood angels would immediately find out that Roy was the real murderer.

At that point, Roy may be in big trouble......

When he was still a low-level demon, he might be able to survive for a while, but now that he has become a high-level demon, what he should face is still what he should face...... After all, the Superior Demon is no longer a nameless existence.

The Angel Legion, led by the six Blood Angels, roared away and began to search for their revenge all over the world, while on the other side, Roy and Juliel, led by the Demon Eye, had gone deep into the ground.

However, they did not come here because the Demon Eye had discovered the traces of the Seven Deadly Sins, but because of ...... The Demon's Eye discovers a surprising scene.

They entered the underground through the underground transportation hub of the human city, which is a neighboring city hundreds of kilometers away from the coastal city where Roy was before, and the surface of this city has long been destroyed, but because it is not close to the coastline, it has not been flooded by the caused tsunami, and the underground buildings of the city are still relatively intact.

However, Rao is so, the all-pervasive demons have already invaded the underground hub here, and the hundreds of demon eyes released by Roy have been scurrying around, and one of them has come to the underground of the city, and in the process of wandering and scouting, the demon eye has sent back a picture.

It was a group of low-level demons, they were underground, besieging a human underground military facility, and the reason for Roy's surprise was here, because in this underground military facility, there were human survivors, it was a group of heavily armed human soldiers!

When Roy controlled the Demon Eye to wander around, he found that this was a very huge underground bunker, it was located 5 kilometers below the surface, it was extended in all directions, very wide, and it was conservatively estimated that it could accommodate hundreds of thousands of people to live here, so Roy immediately thought that this could be an underground nuclear bunker, which is the city's anti-nuclear facility!

Through the picture transmitted back by the Demon Eye, Roy saw that this place had been discovered by the demons, and there were thousands of low-level demons, wandering in the passages of these nuclear bunkers, fighting with humans, and the number of human soldiers in this bunker was also quite large, as well as a large number of civilians, who relied on the thick reinforced concrete and alloy gates to fight against the demons, and in such defensive battles, they repelled the demons' attacks many times, completely blocking the demons from the periphery of the bunker, and could not advance an inch.

But maybe they also know that this situation will not last long, although there is enough food in the bunker, enough for them to survive for a long time, but the demons are endless, and they die one less by one, so even through the eyes of the demons, Roy can feel the pessimism of human beings.

In this regard, Roy can not do anything, he knows that even if these humans do not die in the hands of demons, they will also die in the hands of time, and when War comes again in a hundred years, the humans in this world have been extinct, and in the cruel environment, no human beings can survive for so long, and they have no room to continue to reproduce.

Maybe some of the ancient races who came to the human realm through the passage of another space will be willing to help them, but I'm afraid it's a drop in the bucket, and Roy probably remembers that it seems that the Death of the Four Horsemen of the Apocalypse is also trying to resurrect humans in order to redeem his brother War, as for the final outcome, Roy doesn't know.

However, Roy came here because he had discovered something amazing in this underground nuclear bunker through the Devil's Eye.

That's in the arsenal of human weapons, dozens of tactical nuclear bombs marked with radioactive symbols!
