Chapter 171 Underground Nuclear Bunker

The Blood Oath was the angels’ final trump card!

This was a power that only angels with four wings and above could use. It had to be known that in order to preserve the purity of their souls, angels generally tried their best to maintain their calm and indifferent hearts to reduce their exposure to too many negative emotions. Even in combat, they had to shout slogans of justice to strengthen their will and prevent themselves from falling because of negative forces.

However, the Blood Oath was an exception. Angels were beings with free will, and they had their own siblings, compatriots, and people they cared about and valued, so they would also produce the mentality of revenge due to anger.

The Blood Oath was such a power. It could transform angels through their anger and desire for revenge into blood angels, giving them more strength to help them complete their revenge. This was the origin of the angels of vengeance in human legends… However, blood angels transformed from the Blood Oath, so they had also fallen in the eyes of orthodox angels. This was a sign of anger and vengeance blinding them. But compared to true fallen angels, blood angels still possessed self-awareness and would not stand against angels.

Therefore, the cost of transformation into blood angels through the Blood Oath was immense. The moment the transformation finished, it was equivalent to being exiled and never allowed to return to Heaven again. Moreover, after completing the oath and killing the target of revenge, blood angels would gradually die.

However, the four-winged angels present did not intend to consider more about it. Now that the war situation on Heaven’s side was in an extremely disadvantageous state, even if they did not make Blood Oaths, staying in the human world would not change this situation. It would be better to turn into blood angels and use this opportunity to kill one or two demon lords.

For hundreds of millions of years, the hatred between angels and demons in this world had long become so deep that it could no longer be resolved. Especially after the End War began, the angels were also affected and began attempting some desperate actions…

They would strive to succeed or die trying for their righteous cause.

After making the decision, the angels’ ritual was soon ready. They engraved a huge golden magic formation on the spot, and around one thousand low-level angel soldiers knelt on one knee around the magic formation. They inserted their weapons into the ground, and in the magic formation, the six four-winged angels were facing each other and also kneeling on one knee.

With their heads down and one hand over their hearts, they began to pour magic power into the magic formation while chanting softly.

Gradually, the magic formation started emitting a dazzling light that enveloped the six four-winged angels. As time passed, the color of the light slowly changed from golden to blood-red, and the four-winged angels enveloped in it let out painful roars at the same time.

However, they forced themselves to endure and persisted until the ritual finished.

When the light of the magic formation gradually faded away, what appeared in the eyes of the angel soldiers were six kneeling blood angels!

Their appearance did not change much, but the wings gathered behind them turned from white to blood-red. Even the angelic armor and swords on their bodies were dyed with blood-red halos. At the same time, the aura of surging magic power burst wantonly from their bodies.

The Blood Oath did not promote them, but it could stimulate their potential and temporarily strengthen them. Originally, five of these six four-winged angels were virtue angels, and one of them was a lower-level power angel. But after completing the Blood Oath, they all became existences at the dominion angel level.

It could be said that they were all not weaker than Uriel at her peak…

This way, with six dominion angels in total, even if they really encountered a demon lord, they would have the strength to fight. In addition, with a large number of low-level angel soldiers cooperating with them, this was a military force that could not be ignored.

Most importantly, the Blood Oath could identify the revenge targets of their prayers, and the targets were the murderers of Abaddon and Uriel!

The former was, of course, Demon Lord Straga, but the latter… was Roy!

The angels were all wrong. They thought that the one who killed Uriel was a demon lord, but they did not expect that the one who truly killed Uriel was Roy, a high-rank demon. Uriel was injured at that time and was not in good condition, and Roy and Julia had used the Expulsion incantation on Frostmourne to suppress Uriel’s magic power. Only with these things together could they successfully kill her. Otherwise, if it were a one-on-one battle, Roy would still be lacking in strength when facing Uriel in perfect condition.

But battles were like this. In life and death situations, who cared if you were at your peak? Roy only needed to do everything possible to kill Uriel.

However, after killing Uriel, an important figure of Heaven, the subsequent consequences arrived. Roy had never thought that a group of four-winged angels had chosen to transform into blood angels to avenge Uriel. If Roy encountered them, these blood angels would immediately discover that Roy was the true murderer.

At that time, Roy might be in big trouble… If he were still a low-rank demon, he might be able to avoid them and survive, but now that he had become a high-rank demon, he would still have to face what he had to face… After all, high-rank demons were no longer nameless existences.

Under the guidance of the six blood angels, the angel army whizzed through the air and began searching all over the world for their revenge targets. On another side, Roy and Julia had already gone deep underground under the guidance of a Demon Eye.

However, they had come here not because the Demon Eye had found traces of the Seven Deadly Sins but because… it had found a surprising scene.

They had entered underground through the underground transportation hub of a human city. It was a neighboring city hundreds of kilometers away from the coastal city that Roy had been. Similarly, the surface of this city had long been destroyed, but since it was not close to the coastline, it had not become submerged by huge tsunamis, and the underground buildings were still relatively intact.

However, even so, the all-pervasive demons had long invaded the underground hub here. The hundreds of Demon Eyes that Roy released darted around everywhere, and one of them came to the city’s underground. While wandering and investigating, the Demon Eye transmitted a scene back.

It was a group of low-level demons attacking an underground human military facility. The reason why Roy was surprised was that there were still human survivors in this underground military facility. They were a group of fully armed human soldiers!

After Roy controlled the Demon Eye to wander around, he found that it was an extremely huge underground bunker. It was five kilometers below the surface, had paths extending in all directions, and was very wide. It could probably accommodate hundreds of thousands of people, so Roy immediately thought that it might be an underground nuclear bunker, the nuclear defense facility of this city!

Through the scenes transmitted by the Demon Eye, Roy saw that the demons had already discovered this place. There were thousands of low-level demons moving in the passages of the nuclear bunker and fighting against humans. There were a lot of human soldiers in this bunker and also a large number of civilians. They relied on thick reinforced concrete and alloy doors to fight against the demons. Moreover, in such a defensive battle, they repelled the attacks of the demons many times, completely blocking the demons in the periphery of the bunker and preventing them from entering.

However, they also knew that this situation would not last too long. Although there was sufficient food in the bunker, enough for them to survive for a long time, they could not completely kill the demons and were dying one by one. Even through the Demon Eye, Roy could feel the pessimism of the humans.

Roy was helpless about this. He knew that even if these humans did not die in the hands of demons, they would still die in the hands of time. When War descended a hundred years later, the humans of this world were already extinct. In cruel environments, no humans could survive for that long, and they no longer had the space to continue procreating.

Perhaps some ancient races that came to the human world through alternate space channels would be willing to save them, but it was probably only a drop in the bucket. Moreover, Roy roughly remembered that Death of the Four Horsemen of the Apocalypse seemed to be trying to resurrect the human race to save his brother War. As for the final result, Roy did not know.

However, Roy came here because he found something extraordinary in this underground nuclear bunker through the Demon Eye.

Stored in the human armory were dozens of tactical nuclear bombs with radioactive symbols!
