The old blue dragon had planned to come out of sight.

But I don't want this simple idea to be unsuccessful.

He closed his eyes and endured the sorcerers' tinkering with him for a short time.

A chill that gave him goosebumps all over his body suddenly appeared, making him shiver and having to open his eyes.

He saw the direction that made him extremely uneasy, and immediately understood why.

There was a special building in that direction, a 100-meter-high pyramid made of marble.

This pyramid building was shrouded in a magic circle with deep yin qi, and the two Star Tears magic stones provided by Xiao Yu provided energy as the core.

The pyramid stored the dragon souls extracted from the bones of the blue dragons left after refining the Frost Bone Dragon.

These dragon souls of the Blue Dragon Clan and the Wurm Clan were thrown into this pyramid altar for refining, and under the catalysis of several necromancers, more than a dozen dragon souls had been polluted and turned into ghost dragons.

These ghost dragons slowly grew stronger by devouring the soul fragments of the losers and the yin energy around them.

Originally, according to the process, in order to lay a good foundation and try to cultivate more ghost dragons, this process had to last at least half a month.

As Xiao Yu made the decision to attack in advance.

Naturally, there is no time for these ghost dragons.

Xiao Yu personally came over and opened the Book of the Dead to cast spells, accelerating the growth of these ghost dragons.

Suddenly, there was a sound of fighting and devouring from the pyramid.

These sounds are inaudible.

However, the old blue dragon could feel it deeply, and couldn't stop thinking of the subordinates of the blue dragon clan who were completely disillusioned because of this.

He couldn't help but blame himself in his heart, regretting his arrogance.

If it weren't for his own self-interest, how could he have made things so bad?

It's a pity that everything is irreparable, the big mistake has been made, and there is no way to change it no matter how much you regret it!

Xiao Yu stood outside the small one-meter-high pyramid at this time, paying attention to the input mana while checking the condition of the ghost dragons refining inside.

Soon, an experienced necromancer who had successfully refined several ghost monsters said with a hint of concern:

"Your Highness, we have to stop casting spells, the soul fragments in the graveyard of the dead have been consumed, and if we continue, the ghost dragons may kill each other."

"Don't worry, keep it up."

Xiao Yu nodded lightly and said, "I was still prepared for this. ”

Xiao Yu said this, and with a move of his mind, several undead puppets who had been staying behind him for a long time immediately walked over with two large boxes of white mice.

These white rats also have some origins.

They are the smartest rats specially developed in a research institute in the early 21st century, and they are much smarter than ordinary rats in terms of intelligence.

However, in order to achieve this effect, the institute used the most cutting-edge taboo technology at the time.

Therefore, after the institute published a paper with this result, it encountered an unprecedented storm of public opinion, and then it was blocked by the opposition forces led by Citigroup at that time!

The then commander of Citigroup, Xiaofushi, stood on the rostrum of the United Nations and shouted the slogan: For the purity of mankind!

As a result, the research institute that hit the muzzle of the gun was sealed, and the materials and rats were all collected and sealed by the state.

After the appearance of the extraordinary event, this intelligent mouse was considered by experts to be a more ideal experimental material close to humans than mice, and was once again urged as a research project, and was quickly noticed by major forces.

As the number of cultivation increased and the business expanded, it was naturally discovered by Xiao Yu.

Xiao Yu only made a move through the An Pei family on the side of the Onmyoji, and easily bought these rats from Citi Country, which were regarded as experimental materials closer to the occult.

Truth be told, these rats are still animals after all, and they can't be called intelligent creatures.

Except for the higher IQ, a series of mutations that occur in the comics are none of them in the real rat colony.

And under the witchcraft, these mice gave Xiao Yu an unexpected joy.

Their souls are as incomplete as livestock, and they are just as broken and broken when they die.

But in terms of quality, it is a grade higher than that of livestock.

and with Xiao Yu's policy of insufficient quality and quantity.

After Xiao Yu didn't have enough soul fragments in the pyramid, he didn't have a desperate slaughter like the previous necromancers to meet his needs.

Instead, they threw the mice directly into it, using their flesh and fresh souls to satisfy the appetites of those ghost dragons.

"Squeak squeak!"

These mice have taken a certain amount of white yuan liquid to strengthen their bodies and ensure the integrity of their souls.

As soon as they were driven into the vicinity of the pyramid, they immediately sensed the uneasiness and screamed.

Many mice instinctively want to escape, but when the enchantment is opened, these mice whose body size is not much different from ordinary house mice cannot break through the enchantment arranged by Xiao Yu.

With a chilling dragon moan, the sound was heard frequently.

The ghost dragons of the pyramid who had devoured the souls of failed evolutionaries floated out.

Their bodies were shrouded in a thin layer of white mist, and there was no substance, but they could still tell that the phantom composed of the white mist was the appearance of a giant dragon.

Most of these ghost dragons are about thirty meters in size in the eyes of Lilliputia.

The largest end was no more than forty meters.

There were seventeen of them, which was slightly smaller than the number of Frostbone Dragons.

However, considering that this was Xiao Yu's first time refining, none of the necromancers who assisted had experience in refining undead dragons.

That's a very good result.

The ghost dragons all had the mark of Xiao Yu, and after getting Xiao Yu's permission, they pounced on those mice like wolves that had been hungry and thirsty for a long time!

"Squeak!"

The frightened mice screamed, but immediately fell to the ground after being pounced, and could only quickly wagging their tails in a feeble struggle.

Xiao Yu was able to see the ghost dragons eating.

There is no blood splattered, flesh and blood flying and other inappropriate pictures for children.

It's just that the mice are quickly aging and withering like plants after being thrown to the ground by the ghost dragons.

However, after a second or two of contact, the ghost dragon let go of the mouse and looked for the target again.

The mouse had turned into a dried corpse with dull fur.

As for the soul, it has long been eaten up.

"Uh...... It's no wonder that the eating appearance of the undead creatures is unpopular. ”

Xiao Yu whispered softly, witnessing the ghost dragons eating.

It wasn't until the hundreds of mice released had turned into their dishes that the necromancers next to them reminded them that it was enough.

Xiao Yu nodded slightly, telling the ghost dragons to stop eating and go back to the pyramid to sleep.

Then this pyramid was put in the back compartment of an electric tricycle by Xiao Yu using the hand of a wizard, ready to be used as a hole card.

"Is it finally over?"

"Hey! Has this giant been so mad that he wants to get the undead dragon? ”

The old blue dragon clearly felt the growth of each ghost dragon, and understood very well that this was due to the fact that he had obtained a large number of high-quality souls and flesh.

He didn't know about the existence of the noble guinea pigs, and thought that Xiao Yu had sacrificed a large number of captives with necromancy to satisfy the thirst of those ghost dragons.
