The scream of the Banshee of Despair, with the megaphone and the echo wall, when she was in the Valley of the Dead, the masters of the Holy Domain of the four major families were almost wiped out, and even a group of Saint Masters were embarrassed, and this time, with the lesson of the last time, Zhuo Aozhi took out thirty echo walls, although the number of the Desperate Banshee was insufficient, but through the thirty echo walls in the special arrangement to distribute the power of the sound, causing continuous damage, and at the same time, the two fierce fighting guys were also injured in the previous fierce battle, At this moment, under the continuous sonic attack, the already inlight injury was directly and completely destroyed the combat effectiveness, when the echo wall was finally destroyed under the continuous impact of the sound wave, the sound gradually dissipated, and when Zhuo Ao came to the scene, what he saw was only two dying demons with only one breath left.

"Bloodline?" As if sensing someone's arrival, the Nightmare Knight Knight raised his head with difficulty, and couldn't help but be surprised when he saw Zhuo Ao.

"To be able to speak under that kind of attack, the physique of the demon is really amazing." Zhuo Ao looked at the nightmare knight who staggered to his feet in surprise, the kind of attack just now, Zhuo Ao asked himself, even if the deity is here, it will not be easy for him, the nightmare knight who was already seriously injured can still stand up, the constitution of the undead is really amazing.

"I remember, not long ago on the road, that impudent undead!" A cold glint flashed in Nightmare Knight's eyes, he had already noticed Zhuo Ao on the road before, and instead of kneeling down like the other undead, he avoided it from a distance, but he was too busy to pay attention to it.

"I really don't know much about the etiquette of the dead." Zhuo Ao shook his head and sneered.

"It's funny that a group of fallen undead nobles have forgotten the etiquette they established in the first place." Nightmare Knight sneered.

"The declining undead aristocracy?" Zhuo Ao chewed on the meaning of this sentence, feeling the coercion that continued to emanate from the Nightmare Knight, and couldn't help but sneer: "Don't be busy in vain, this momentum can't scare me!" ”

He was originally a powerhouse in the Jindan Realm. How could coercion at the same level have an effect on him.

"What do you want to do?" The Nightmare Knight continued to absorb the undead qi, hoping to recover some of his strength as soon as possible, looking at Zhuo Ao with a calm gaze, but he couldn't help but panic in his heart, the undead who were not suppressed by the rank. It was the first time in his long life that he had encountered it.

"Of course it's eating!" A wicked smile appeared at the corner of Zhuo Ao's mouth, his body suddenly flashed, easily avoiding the knight's spear suddenly stabbed by the Nightmare Knight, dodged behind the other party, cut the opponent's arms back with both hands, and faced Osaac, who was silently accumulating strength, his hideous fangs pierced into the opponent's arteries, greedily sucking every drop of the opponent's blood.

"Roar~" felt the continuous loss of blood and power. It is definitely a great shame for him to be miserable to become the food of a blood baron, for him, he would rather die under the great sword of Osaac than die in the hands of a blood baron.

Looking at the nightmare knight who was rapidly drying up, Osaac wanted to make a move several times, but Zhuo Ao's inadvertent glance made him feel an unspeakable fear.

The heart nuclei are constantly pounding. Quickly purifies and absorbs the influx of blood. When the corpse of the Nightmare Knight completely turned into a dry corpse, Zhuo Ao frowned and wiped the blood stains on the corners of his mouth, feeling the new power in his body, a demon at the level of a saint master, but in the end, he only improved his strength to the third order, and now he is still a baron. However, it has only been promoted from the previous fifth order to the current eighth order.

It's not that the other party's blood is not strong enough, but that it is mixed with too much dead energy, although the blood clan is an undead creature, but what is needed to advance is fresh and vibrant blood, this kind of blood full of death breath. It doesn't help him much, this is also because the other party is strong, if it is just the same level of blood, it will not have any effect on Zhuo Ao at all.

No wonder the blood clan likes to run to the world, although the strength of mortals is not strong, but the blood in the body is very pure, it will not be mixed with so much dead gas, devouring a mortal of the same level, the effect is definitely not much worse than devouring a demon at the level of a holy domain, although it has a long life, but in the underworld, the survival potential of the blood clan is actually not large, after all, not every blood clan has this opportunity to meet two seriously injured and dying saint master powerhouses.

The prey that is desperately captured, and the blood energy that can be contributed in the end is not even enough to supplement their own consumption, such a huge contrast, no wonder it will be called a declining noble, the blood clan is in the underworld, and there is really no development potential.

"Let's talk?" Feeling that the help of the Saint Master level demon clan was not strong, when Zhuo Ao's eyes looked at Osaac, he didn't have the greed he had before, and with an elegant smile on his face, he looked at Osaks.

"Humph!" Osaus silently raised his broadsword and swung it at Zhuo Ao.

"Now you're really not too suitable for fighting." A giant sword that lined up the other party, Zhuo Ao shook his head.

"You shouldn't be a blood baron, a blood baron, it's impossible to avoid this sword!" Although he was seriously injured, he was a saint-level powerhouse after all, even if his strength was insufficient, a sword wielded by a saint-level powerhouse contained some mysteries in itself, just like a grandmaster-level spearman's own strength was not strong, but a shot was enough to kill the enemy beyond the ranks, at least his sword could not be dissolved by such an understatement by a blood baron.

"Now I, my strength is indeed a blood baron." Zhuo Ao shook his head and said indifferently, but the realm, at least it is not worse than you, and silently added a sentence in his heart.

"What do you want to say?" After a moment of silence, O'Sachs said in a deep voice, the other party had the strength to kill him but did not make a move, so he simply let down his guard, anyway, the situation will not be bad anymore.

"Make a pact with me." Zhuo Ao said.

"Like those inferior undead, sent by you at will?" O'Sachs obviously couldn't accept this condition, the contract of the dead is not only the patent of the necromancer, in fact, the real founder of the contract of the dead is from the underworld.

In addition to the intelligent races in the underworld, there are also many undead who have no wisdom but have good power, in order to dominate these undead to fight for themselves, the undead contract is gradually formed, once the undead contract is signed, the master can control the life and death of the person who is signed the undead contract at will.

"You don't have a choice." Zhuo Ao's eyes narrowed slightly, looked at Osaachs and said, "Sign the contract of the undead, do things for me, or be drained of my blood and die, just like him, I will give you the opportunity to choose." ”

"I can give you powerful magical weapons, and countless treasures." O'Sachs's hard way, the humiliating death of a nightmare knight, was even more difficult for him to accept.

"I don't lack these things." Zhuo Ao sneered: "Say your answer, my patience is not too good. ”

With Zhuo Ao's voice, a pair of fangs slowly appeared at the corners of his mouth.

"Puff~" Osaac's gaze swept over the dried corpse of the Nightmare Knight, and finally chose to submit, kneeling beside Zhuo Ao, and his deep voice was almost vented in a roaring way: "I, Osaac, swear in the name of the god of the underworld, I will be loyal to the blood clan in front of me, and I will not betray for life, and if I break my oath, I am willing to be burned by the fire of purgatory and die." ”

As O'Sachs's words fell, a strange soul connection was established between the two, and Zhuo Ao felt that he had the ability to control the life and death of the person in front of him, as if he could make the other person die with just a thought.

"Alright, get up." Zhuo Ao smiled slightly, stretched out his hand to help the other party, sat down on the spot, looked at Osaus and said: "Now, tell me about the situation in the underworld, from the strength of the underworld, and how many intelligent races in the underworld like your underworld demon race, in short, the more detailed the better." ”

"Huh?" O'Sachs looked at Zhuo Ao suspiciously, these seem to be common sense questions in the intelligent races of the underworld.

"Don't look at me, I grew up in the human world, I just came to the underworld, and I don't know anything about the things in the underworld." Zhuo Ao said with a smile.

"What?" O'Sachs was even more depressed, a blood baron who had just come down from the human world, playing with the two demon marshals in applause, this feeling was not too good.

"Then I'll start simple." After being shocked, looking at Zhuo Ao's gaze, Osaacs slowly began to pick up with a depressed face: "Now, the underworld is ruled by three major races, namely the Dark Demon Clan in the Dark Forest, the Fallen Angel Clan who occupies a dominant position, and the strongest warriors in the Underworld, the Hades Demon Clan, these three major races surround the Doomsday Canyon, ruling different areas, and of course, there are some other races, such as succubus, fire demons, blood clans, fallen elves and many other races, all of which are attached to the three major races. Serving the three major races, the boundaries of the three major races are not obvious, and they can also be subdued by each other, for example, I was loyal to a strong man of the fallen angel Crow Houston at the level of a demon king. ”

"Demon King?" Zhuo Ao looked at O'Sachs.

"Corresponding to the strength division of your blood clan, the demon king should be equivalent to the existence of the marquis, although each race has its own method of dividing the strength, but the underworld has a set of general strength classifications, from low to high are the demon pawn, the demon general, the demon handsome, the demon king, the demon emperor, the demon emperor and the legendary demon lord, but the underworld has not appeared in the demon venerable for a long time, and now the underworld is controlled by the three major demon emperors."

Zhuo Ao nodded when he heard this, this division is clear at a glance, in terms of level, it is similar to the other world, but the strong people in this underworld don't know what to cover, and the masters all announce their names to the public.

Immediately after learning about the distribution of forces around him, Zhuo Ao finally breathed a sigh of relief, although the strong in the underworld are like clouds, the weak eat the strong, but there are also some rules, as long as you don't touch these, it will generally be fine.
