The demonic blood defenses of the two magic castles "Heavenly Tribulation" and "Eternal Darkness" are very powerful. This is a nearly perfect city defense weapon system created by the Seven Demon Lords of Hell.
But "almost" perfect means that it has not actually reached perfection.
Therefore, this defense system actually has loopholes.
Its flaw is that the gap between the power of the Demon King's blood and the power of the Demon God's blood is too large, and it is difficult for the balance system of Demon Blood Runes to smooth out the gap between the two levels of power.
Therefore, if this defense system only uses the blood of the Demon King, then only a single Demon King rune will fall into a short cooling phase after use, but other Demon Blood runes will not be affected.
However, once the defense system activates the runes constructed with the Demon's Blood, then after the runes are used up, due to the huge power required to activate the Demon's Blood, the entire defense system will be paralyzed for a short period of time!
At this stage, the rune defense system cannot be activated. It is like the machine is overloaded and must be allowed to cool down completely before it can be used again.
This is the experience that the angels discovered in the battles against the two magic castles. This short period of paralysis is when the defense of the magic castle is the most vulnerable!
In fact, the angels have tried to take advantage of this paralysis period to capture these two fortresses several times, but the demons obviously also know the loopholes in the demon blood rune defense system, so they rarely use demon runes for defense.
Even if they are used occasionally, they will be prepared to defend against the angels' raids in the magic castle. Coupled with the huge power of the demon rune itself when activated, the angels' tactics of exploiting this loophole have never been successful.
But this time, Yizuer obviously miscalculated.
It did not expect that among human extraordinary beings, there would be such a capable person, who could actually bear the terrifying tide caused by the Blood of Destruction alive with the power of one person!
At this moment, on the top of the "Heavenly Tribulation" fortress, the ferocious face of the fallen angel Yizuer was filled with gloom.
As soon as the huge golden wall appeared just now, it found the source of the familiar feeling from its memory!
"It turns out to be the blood of the ancient kings of mankind... No wonder I always feel that this power looks so familiar..."
"I just don't know which bloodline it was at that time?"
Just when Yizuer's face seemed to have a hint of amusement as if he remembered something interesting, a long sword covered in blue holy fire suddenly appeared above its head and slashed hard at his head.
!
"Death! Traitor!"
Clang!!
Blue-white sparks spattered in all directions during the exchange of the two holy swords. In the aftermath of the energy explosion, Yizuer grabbed his "Blue Fury" and firmly held the one in Tyrell's hand.
"Adruin"!
"The bloodline of the ancient kings has formed an alliance with the angels in heaven? Don't you think this is really interesting! Tyrell!"
Yizuer laughed wildly and exerted his strength, and the blue anger pulled out a sky-blue light strip in mid-air. Sparks flew everywhere where the two swords collided, and Tyrell was forced to step back.
At the same time, hundreds of demon kings holding black magic blades swarmed towards Tyrell from the surrounding cities, trying to capture the Archangel of Justice.
"There are still many things you don't know, Yizuer. Your ignorance now is exactly the same as that of you back then!"
boom!
Tyrael swung his long sword mercilessly, and the blue holy fire blazed across the sky, instantly burning the elite demons who rushed forward into ashes all over the sky.
"Shut up! You coward! Cowardly reptile! Hypocritical scum!"
Yizuer was so angry at his ridicule. No matter what kind of clay figurine you are, no one can bear the thought of others bringing out your past scandals over and over again to provoke you.
What's more, Yizuer is now a demon, and demons have always been famous for their explosive tempers...
It raised its blue fury, the bat wings behind it shook, its entire body flew into the air, and then it quickly pounced on Tyrael in mid-air!
Clang!
The two holy swords collided in mid-air again, and after this collision, the former brothers and colleagues started a fierce battle without mercy!
Ding ding ding...!!!
The crisp sound of steel hitting each other continued to be heard from the angels and demons in mid-air. The speed of their sword swings was far beyond what extraordinary beings could see clearly.
The two holy swords constantly collided in the fierce battle. Every time they collided, countless invisible winds would erupt. These winds were like indestructible but invisible steel knives. No matter what they hit, they could
Easily cut the thing into two pieces, and even the ground of the battlefield was plowed out by the strong winds with countless long and short cuts!
Over the city of the "Heavenly Tribulation" fortress, the battle between two extraordinary masters brought disaster to the demonic troops on the city.
The aftermath of those battles and the strong winds are not long-sighted, and whoever encounters them will be in serious trouble.
Especially those slow-moving Hellfire Bed Crossbows were quickly destroyed one after another. The temporary Castlevania defense officer could only desperately organize the forces in the fortress and let them continuously go to the top of the city to fill the defense gap.
The failure of the demon blood defense system caused the outer shield of the entire fortress to lose its effectiveness, so Tyrell could rush to the top of the city so easily.
Without the magic blood defense and the city shield, the "Heavenly Tribulation" Demonic Castle is just an ordinary fortress with slightly higher walls. In this case, the demonic defenders in the city can only rely on their own strength.
They must rely on the most primitive way of defending the city to survive the cooldown period of the magic blood defense!
The professional army and the angel army outside the city have now successfully recovered from the previous state of losing all their strength. They are seizing this rare fighter opportunity under the leadership of Bulkeso, preparing to break through the "Heavenly Tribulation" fortress in one fell swoop.
Line of defense!
At the same time, on the other side of the battlefield, the demons in the "Eternal Darkness" Magic Castle have apparently discovered the dangerous situation in the "Heavenly Tribulation" Magic Castle.
The demon commander in the city immediately realized that humans and angels must not be allowed to take advantage of the failure of the demon blood system of the "Heavenly Tribulation" fortress to capture the "Heavenly Tribulation" fortress.
It immediately sent out a large number of demonic troops to attack the flanks of the angel and professional legions from the south of the battlefield.
However, not long after this demonic force walked out of the "Eternal Darkness" fortress, they were encountered at the junction of the defense zones of the two fortresses by the two angelic legions of destiny and wisdom, as well as an army consisting of two human extraordinary beings and three legendary level warriors.
The ambush of the legions of human professionals led by professionals.
The allied forces of professionals and angels relied on the presence of extraordinary beings in their own military formation to push the demonic reinforcements, who still had the upper hand in numbers, to the ground and beat them severely.
The commander of the demon reinforcements quickly realized that the situation was not good and quickly ordered a retreat. As a result, the angel and professional coalition forces pursued them all the way, and almost followed the defeated soldiers directly into the gate of the "Eternal Darkness" fortress.
If the demonic blood runes of the "Eternal Darkness" Fortress hadn't helped them block the pursuing troops of angels and professionals, I'm afraid a big mistake would have happened on the "Eternal Darkness" Fortress...
