Among these three demon pets, the Soul Devouring Mouse has the lowest probability of breaking through, and due to the failure of the last breakthrough, there is only about a 7% chance of breaking through the Demon King level.

With the help of the Mysterious Crystallization of Secondary Fire this time, there is about a 30% chance of breaking through.

It's hard to say about the Ancestor Leopard Beast, if its quality rises to a half-step epic, there will probably be a forty percent breakthrough probability, and if the quality is not improved, the probability is only about two percent.

In addition, if the quality reaches a half-step epic, even if the breakthrough fails, Li Changsheng doesn't have to worry anymore, even if he doesn't use any auxiliary resources, he can break through the demon king level within a year or two.

Before starting the breakthrough, Sylvanas carefully grasped the Arcane Crystal of Secondary Fire, which was not much bigger than dust to it, but extremely important to it.

Xi'er Asuna knew very well in her heart that it was just Li Changsheng's temporary demon pet, and if this breakthrough failed, she didn't know how long it would take to have such a chance next time.

Don't miss the opportunity, lose it again!

Xi'er Asuna cherished this opportunity and was more determined than ever.

Roar~

Sylvanas roared at his five-colored dragons, as if warning them not to make a sound, or face the consequences.

The nine-headed adult five-colored dragon was suddenly silent, and during this time, they were tossed by Xi'er Asuna, especially the rules set by Xi'er Asuna.

In order to improve the probability of giving birth to dragon eggs, Xi'er Asuna can be said to do everything, not only specially stipulating the number of circles and forks of the five-colored dragons under her hands, but also letting the female dragon lie on her back on the ground afterwards to increase the pregnancy rate of the female dragon.

In addition, it is to train this group of five-colored dragons to the death, and reluctantly blend them into a group, and there is a certain degree of cooperation between them, and they are no longer completely scattered as before, and they are easy to be broken by each one.

Under the 'tyranny' of Sil Asuna, these nine adult five-colored dragons have surrendered from the bottom of their hearts.

Only then did Hir Asuna retract her gaze with satisfaction, and lay on the ground to absorb the mystical crystals of the secondary fire.

Not far away, the Ancestral Leopard Lin Beast and the Spirit Eater Mouse had already entered a breakthrough state first, filled with energy of different colors.

Li Changsheng paid close attention to them, and standing with him were Li Haoqiong and his wife.

While the Ancestral Leopard Lin Beast and Xi'er Asuna were still digesting the treasures of heaven and earth, the consciousness of the Spirit Devouring Mouse had already entered the depths of the sea of consciousness and began to impact the threshold of the mystery.

Li Changsheng's spiritual power has always been in a state of release, always paying attention to the Ancestor Leopard Lin Beast.

In the process of refining the origin of thunder, the point of light representing the Ancestor Leopard Lin Beast was becoming brighter and brighter at a speed visible to the naked eye, and it was about to reach a critical point.

Li Changsheng was a little more nervous in his heart, whether the quality of the Ancestor Leopard Lin Beast could reach the half-step epic, the key was at this moment.

After reaching the critical point, the point of light representing the Ancestral Leopard Beast flickered like a red light on Ultraman's chest.

Under Li Changsheng's expectant gaze, suddenly, the point of light representing the Ancestor Leopard Lin Beast shone brightly.

Li Changsheng immediately showed a smile of joy, which meant that the quality of the Ancestor Leopard Lin Beast had successfully risen to a half-step epic.

After the quality increased, according to Li Changsheng's instructions, the Ancestor Leopard Lin Beast's consciousness immediately entered the depths of the sea of consciousness and began to hit the threshold of the mystery.

Soon after, Sil Asuna finally absorbed the mystical crystals of the secondary fire and also entered the depths of the sea of consciousness.

Compared with the extremely pure Fire Mystic Crystal, the secondary Fire Mystic Crystal has a certain magazine, and the increase and durability of Xi'er Asuna are naturally not as good as the former, but it is also commendable.

Soon, three minutes passed.

Creak~

At this time, the Soul Eater opened its eyes, and its cry was full of disappointment.

Just like the last time the Bathing Emperor Slurry, the Spirit Devouring Rat failed to break through again, and the probability of breaking through next time is probably less than 5%.

Li Changsheng didn't have many surprises, in this case, he decided to prepare a treasure for the Spirit Devourer Rat to assist in the breakthrough class, or the kind of treasure that greatly increased the probability of breakthrough.

He definitely doesn't attach as much importance to a temporary demon pet as a formal demon pet, like the difference between a pro-son and a godson. However, the Spirit Devouring Mouse is a little different, perhaps its strength is the weakest among the many demon pets, but it is the first temporary demon pet that Li Changsheng has subdued, and it has repeatedly performed miraculous achievements, and its accumulated merits are higher than most demon pets.

Not to mention anything else, the petrified phoenix egg alone cannot be measured in value.

Not long after, the Ancestral Leopard Beast also opened its eyes, and it failed to break through like the Spirit Eater Rat.

However, the Ancestral Leopard Beast is now a half-step epic quality, and even if it fails many times, its breakthrough probability will always remain at about 20%.

In this way, only Sil Asuna remains.

If Xi'er Asuna fails to break through, then this time, in addition to the improvement of the quality of the Ancestor Leopard Lin Beast, there will be no gain.

Roar~

It didn't take long for Hir Asuna's dragon body to emerge with wisps of mystical energy, and under the transformation of mystical energy, the already huge dragon body began to grow at a speed visible to the naked eye.

Hir Asuna hadn't woken up yet, and judging by the situation, it had only broken the threshold of the mystery, not yet completely shattered it.

If you can't smash all the arcane thresholds, then it can only be a pseudo-demon king-level demon pet, but you can break through the demon king level at any time in the future, and like the half-step epic quality, at least the demon king-level seat is locked.

In just a few breaths, Xi'er Asuna's dragon body has exceeded forty meters, and the mysterious energy on its body surface has become more and more powerful, so that its dragon body has never stopped growing.

At the same time, these fiery red mystical energies suddenly condensed and contracted, revolving rapidly around Hir Asuna, faintly forming a fiery red film, which was the mystical guardian, but it had not yet been fully formed.

It didn't take long for Xi'er Asuna to finally exceed fifty meters under Li Changsheng's expectant gaze, which can be said to be a sign, almost representing Xi'er Asuna's successful promotion to the demon king level.

It was also at this time that Xi'er Asuna suddenly opened a dragon eye larger than a lantern, and raised her head to the sky and let out a majestic and domineering dragon groan, which was magnificent, and it was completely different from before.

The dragons in the dragon's lair only felt their hearts sinking, and under this majestic and thick dragon power, they seemed to be carrying a big mountain, and their bodies began to tremble.

Only the golden dragon Hermes was not affected too much, because compared to Sil Asuna, the dragon power of the second-level ancestor black dragon was superior.

"Xi'er Asuna, what should you do if you restrain your damn dragon power and scare the children?"

Li Changsheng's dissatisfied voice sounded, if he hadn't made a timely move to protect the newly hatched red dragon cub, otherwise this red dragon cub would really be scared to death.

Due to the relationship between the weak water array of Tianhe, Xi'er Asuna's promotion vision was naturally undetectable by outsiders.

"I'm sorry, my stupid sister!"

Xi'er Asuna hurriedly reined in Long Wei, it naturally would not disobey Li Changsheng, it has the current achievements, and it is completely brought by Li Changsheng.

As for the sister in Xi'er Asuna's mouth, she was naturally referring to the red dragon cub, and Li Changsheng didn't expect that the king of the red dragon, Yana Sans, was at the level of a demon king, and he still maintained such a high fertility rate, which was simply a model among dragons.

However, the last red dragon egg is not the heir of the red dragon king Ya, its mother is the red dragon contracted by Xu Wenhua.

Thanks to Li Changsheng's blessing, Xu Wenhua's red dragon has been promoted to the demon king level.

It's a pity that this dragon egg was born before the red dragon advanced to the demon king level, so naturally it won't get any benefits, and it won't be any different from ordinary red dragon eggs.

Roar~

The red dragon cub let out a dissatisfied immature dragon groan, expressing its dissatisfaction.

Xi'er Asuna stretched out a little finger, and with a single touch, the red dragon cub was pushed to the ground.

The red dragon cub got up from the ground, grabbed Hir Asuna's fingers, and opened its mouth to bite.

Unfortunately, apart from its own sore gums, Hira Asuna was not affected in any way, and it was like tickling, and it couldn't be broken at all.

While Xi'er Asuna was teasing the red dragon cub, Li Changsheng began to check its information.

[Fairy Name]: Red Dragon (Growth Period, Top Alien Beast. Comprehend the mystery and greatly increase the power of the skill, and the arcane guardian: Immunity from some damage, mainly depends on the opponent's realm. ）

[Fairy Realm]: Demon King 1st Order

[Fairy Race]: High Sovereign

[Fairy Quality]: Excellent

[Fairy Blood]: Ancestral Red Dragon (Rich)

[Fairy Attribute]: Fire

[Fairy Status]: Healthy

[Fairy Weakness]: Water

With Xi'er Asuna's promotion to the demon king level, after the second-level ancestor Black Dragon and the Heaven Heavy Pupil Bird, Li Changsheng has a third temporary demon king-level demon pet.

Including the temporary demon pets, Li Changsheng has nine half-demon king-level demon pets.

After Xi'er Asuna became a demon king-level demon pet, Li Changsheng had to change his plan temporarily, he couldn't leave his powerful combat power in the dragon's lair, it was really a waste.

It's just that what gave Li Changsheng a headache was that after taking away Xi'er Asuna, he didn't have a suitable demon pet in his hands.

Originally, the best alternative should be the two-headed dragon, even if the two-headed dragon only has the leader level realm, but it can definitely defeat ordinary adult dragons, I am afraid that it will not be long before its combat power can reach the level of Xi'er Asuna, who has not yet advanced to the demon king level.

It's a pity that the two-headed dragon belongs to the atavistic bloodline, and it must follow Li Changsheng anytime and anywhere, otherwise if something goes wrong, Li Changsheng is afraid that he will even regret his intestines.

The second alternative is the Dragon, but its combat power is not inferior to that of an ordinary demon king-level demon pet, and it is the only space-based demon pet in Li Changsheng's hands, which cannot be replaced.

As for other demon pets that have not reached the level of the demon king, they are even more unsuitable.

There is no way, Li Changsheng can only let the golden dragon Hermes shoulder to shoulder, its combat power is no worse than that of Xi'er Asuna before the promotion, plus there is Li Haoqiong and his wife to help him, there should not be too much chaos.
