After a while, the One-Horned Ancestor Demon spoke again: "Okay boy, you don't have to ask for a price, this ancestor can pay you a hundred drops of demon blood in advance, but you must hand over the souls of ten thousand gods to this ancestor within a month!"

"No! 100 is too little, at least 9,000 drops!" Cheng Bo had no fear to ask for a sky-high price.

"Boy, do you know what a drop of demon blood represents? if an evil demon obtains a drop of demon blood from the deity, it can at least be upgraded by one rank!"

"Ten thousand drops!" Cheng Bo said lightly.

"What's the price going up?" "The One-Horned Ancestral Demon had the idea of killing this kid.

"No matter what else, a hundred drops of this kind of small business, the master doesn't bother to do it, either it's ten thousand drops, or you find someone else!" Cheng Bo said with a smile, as if he had decided to eat the one-horned ancestral demon.

Hearing this, the one-horned ancestral demon was angry and roared, "Boy, do you know the value of demon blood?"

Cheng Bo plucked his ears: "11,000 drops!"

One-Horned Ancestral Demon: "......!"

After the one-horned ancestor demon was silent for another quarter of an hour, he spoke again: "Boy, I have a large number of descendants, if you don't agree to cooperate with this ancestor, believe it or not, this ancestor ordered the descendants to hunt you down in the whole universe!"

"Descendants?" Cheng Bo smiled: "Your news is behind, your demon clan has a demon emperor, in order to prevent your recovery, he has killed all the demon emperors and high-level demons, and taken away the demon domain, so, if you want your descendants to hunt down and kill me, it is impossible at all!"

"Impossible!"

The One-Horned Ancestral Demon roared again: "How dare he betray us!"

Cheng Bo smiled: "Hehe, believe it or not, you might as well communicate with your descendants!"

With suspicion, the one-horned ancestral demon communicated with his descendants, but he did not get a response for a long time, that is to say, most of his descendants had fallen, for a while, he believed Cheng Bo's words seven or eight points, and at the same time, his heart was more angry, the Demon Emperor actually dared to betray them.

"Boy, this ancestor can pay you a thousand drops of demon blood in advance, but every month, you have to send a batch of divine souls to this ancestor, and if the deity gets out of trouble in the future, I will accept you as an apprentice!"

"Deal!"

Cheng Bo said very happily.

Then, a thousand drops of demon blood flew out of the one-horned ancestral demon's body, Cheng Bo was unceremonious, urging the devouring divine power to involve the thousand drops of demon blood in his body, and then urging the divine power to refine, and suddenly, a terrible sound came from his body.

The one-horned ancestral demon is not a good stubble, how could such an old treacherous and cunning be played by Cheng Bo, everything just now was just acting, because he moved his hands and feet in the demon blood.

Therefore, Cheng Bo cooperated with him to act, and there was no hidden prohibition hidden in the demon blood before refining, but this time, with a thousand drops of demon blood in his hands, he naturally didn't need to act with the other party anymore, and directly urged the devouring divine power to forcibly refine those prohibitions.

"Boy, you dare to fool me!"

The one-horned ancestor demon shouted angrily, and when he woke up, he was calculated by the kid in front of him, and he lost more than a thousand demon blood in vain.

"I'm playing with you, it's you who did it in the demon blood, right?"

Cheng Bo looked at the other party with a sneer: "If the hidden prohibition in these demon blood is completely triggered, it is enough to turn me into a puppet of yours, if you want to calculate me, I will let you steal chickens and rice!"

"Good boy, you are ruthless, but you also need to be proud, when the ancestor is out of trouble, the first one to cut you down!" the one-horned ancestor demon roared wildly.

"Huh!"

Cheng Bo smiled, no longer paying attention to the one-horned ancestral demon, but wholeheartedly refining the demon blood in his body.

More than a thousand drops of demonic blood turned into energy constantly tempered his physical body, constantly pushing his physical body to a new height, and when he refined all the demonic blood, the strength of his physical body increased by at least dozens of times.

"It's too domineering!"

Cheng Bo sighed, his eyes staring at the one-horned ancestral demon, and he didn't know if his devouring divine power could devour the other party when it was a hundred times weaker?

Feeling Cheng Bo's eyes, for some reason, the one-horned ancestor demon actually felt a little more uneasy in his heart.

"Boy, what do you want to do?"

"Guess!"

Cheng Bo smiled evilly, and there was an extra card in his hand.

As soon as his mind moved, the card turned into a streamer and sank into the body of the one-horned ancestral demon, and suddenly, the one-horned ancestral demon was horrified to find that his strength was weakening at an extremely fast speed, and in an instant, his strength plummeted a hundredfold.

"Aung Aang Aang!"

In a burst of dragon groaning, nine brilliant rays of light burst out from Cheng Bo's body, and then, he directly turned into a real dragon.

The dragon's claws poked out, and with an extremely strong sense of tearing, they landed on the body of the one-horned ancestor demon.

"Puff puff!"

For a moment, several deep wounds appeared on the chest of the One-Horned Ancestral Demon, and a large amount of blood flowed out of the wounds.

"Ah, little thief, my one-horned ancestral demon swears that I will smash your body into ten thousand pieces, and then use the magic fire to scorch your soul for nine million years before killing you!"

In response to the One-Horned Ancestral Demon, another claw added another wound to his body.

Next, Cheng Bo shot frantically and kept grabbing the one-horned ancestral demon with his dragon claws, but what made Cheng Bo sigh was that this one-horned ancestral demon was too strong, even if his strength was weakened a hundred times, his dragon claws still couldn't really hurt him, and it could only bring some skin injuries.

But that's enough.

With this manipulation, the demon blood he obtained was not only ten thousand drops, but one hundred thousand drops were enough.

After Cheng Bo had collected all the demon blood, the effect of the card had disappeared, and then, the wound of the one-horned ancestral demon healed rapidly, and not a single drop of blood flowed down.

"Good harvest!"

Cheng Bo recovered his body, smiled, and urged the devouring supernatural power to frantically refine the collected demon blood.

With the refining, he stored a large amount of pure energy in his body.

Some are used to strengthen the body, and some are used to strengthen the soul.

One day.

Two days.

Three days.

……

It wasn't until the 11th that Cheng Bo refined all these demon bloods, and his body and soul had been fully improved, but he felt a kind of imprisonment, that is, no matter how much he strengthened his body and soul, he could not reach the level of the main god.

It seems that the surface universe has an extremely strict development of the number of main gods, and if you want to become the eighth main god, you have to pay more than the seven main gods.

However, his strength does not only come from the body and soul, don't forget that there is also "Nine Changes of the True Dragon".

Since neither the body nor the soul can be improved, then increase the power of the dragon.

Then, Cheng Bo had another card in his hand.

"Boy, what do you want to do?"

The One-Horned Ancestral Demon roared.

"Hey, hey!"

Cheng Bowei laughed, directly urged the card, and with a whooshing sound, the card turned into a streamer and sank into the body of the one-horned ancestral demon.

That feeling came again.

"Damn thief!"

The one-horned ancestor demon wants to cry without tears, and my generation of dignified ancestor demons actually ended up like this.

And Cheng Bo turned into a real dragon again, frantically attacking the one-horned ancestral demon, and cut a large number of wounds on his body.

When the weakening time passed, Cheng Bo took the collected demon blood and entered the cultivation again, this time, he improved the power of Jairus, if he let the power of Jairus complete the seventh transformation, his strength after transformation will increase a lot.

More than ten days later, Cheng Bo smiled with satisfaction, and the power of the eyes was about to reach the requirements of the seventh change.

"Come again!"

Cheng Bo took out another weakened card.

Three days later, the power of the eyes in Cheng Bo's body reached its peak and began to enter the seventh transformation.

Then, Cheng Bo poured the refining energy into another kind of dragon power.

More than 100 days have passed before you know it.

Cheng Bo, who was sitting in the sealed time and space, stood up, raised his eyes and looked at the one-horned ancestral demon who had lost a lot of weight, Cheng Bo had an inexplicable pleasure in his heart, what if you are the top 100 powerhouses on the list, it is not that you can only be bled obediently by the young master.

At the same time, eight of his nine sons' powers had already completed the seventh transformation, and the last one had also reached the edge of transformation, and only tens of thousands of drops of demon blood were needed to meet the requirements.

It's a pity that all ten weakened cards have been used up.

As a result, Cheng Bo's figure flickered, and he appeared in the twenty-ninth level mall space.

Consume a billion divine crystals to turn the wheel, and he still has to draw weakened cards.

Bye!

When the pointer stopped, Cheng Bo couldn't help but be disappointed.

"Come again!"

This time, he directly consumed two billion divine crystals to spin the roulette.

Still a bye.

"!"

Cheng Bo didn't believe in evil, and consumed two billion divine crystals again.

Fortunately, there is no bye this time, but this time it is not a weakened card, but a card with another function, which is a substitute death card, which is a passive card, and only after being killed, will the effect be activated.

"It's a good thing, too!"

Throwing one of the death cards into the system backpack, Cheng Bo continued to spin the wheel.
