After the test, Mo Yu did not retreat for the first time to seek a breakthrough.

His cultivation began to be unhurried and impatient, practicing the fighting qi for two hours a day, and then he went to the back mountain to practice Lei Gang's body, and occasionally had free time, he was to chat with his grandfather, the only relative.

And after five days of such an easy time, Mo Yu finally adjusted his physical state to the peak, although he had rich experience in his previous life, it was not worth mentioning to break through the little fighter.

But Mo Yu has always pursued to be prepared and not to be negligent in doing things.

And this is the best moment for him to impact the fighter.

……

In the mountain behind Utan City, under a hidden cliff, Mo Yu sat cross-legged in this cave that was only more than two meters wide, and this cave was his carefully selected place to cultivate.

There are few people here, and even birds and beasts can't be seen, let alone anyone will disturb them, so it can be said that it is extremely secretive.

Slowly taking a breath, Mo Yu took out the ring from his arms, and his soul power probed into the ring, and two second-order demon cores appeared in his hands.

Looking at the second-order demon core that was far more violent than the first-order demon core and contained more violent heaven and earth energy, Mo Yu smiled slightly, then opened his left hand, and a red thunder snake suddenly appeared, and the sound of squeaking electricity resounded throughout the cave.

"After three months of solidity, it's time to break through the fighter!"

The foundation of the original body was too poor, and in a year of traversing the Dou Qi Continent, Mo Yu quickly broke through to the ninth stage of the Dou Force, and the improvement of the fifth stage in a year was even more amazing than Xiao Yan's fourth stage in a year.

Therefore, Mo Yu deliberately suppressed the realm breakthrough, otherwise once the foundation was unstable, it would cause irreparable damage to the future.

And after three months of training, Mo Yu was also fully prepared at this time.

Suzaku Burning Sky Thunder summoned out, Mo Yu's face froze, and he directly threw the second-order demon cores of the fire and thunder systems into it.

With the input of the two magic cores, the red thunder suddenly began to tumble, and a squeaky electric sound also came from the cave in a steady stream, fortunately, this place is inaccessible, otherwise it will definitely attract some good deeds.

As the red thunder continued to devour, the hard shell of the demon core was also constantly dissolving, and at the same time, a majestic and violent heaven and earth energy was also gushing out from it.

"It is worthy of a second-order demon core, and the energy contained in it is probably ten times higher than that of the first-order."

Looking at the heaven and earth energy pouring out from the demon core, Mo Yu couldn't help but be surprised by its number when he felt its incomparably furious.

I'm afraid that in the entire Dou Qi Continent, only he can absorb the energy of the second-order demon core at the Dou Qi stage.

Before you know it, a day and a night have passed.

In the continuous devouring and absorption of the Vermilion Bird Burning Sky Thunder, the demon core, which was originally half a fist in size, had shrunk to the size of only half an egg.

At this time, the Vermilion Bird Burning Sky Thunder was like a real thunder flame, blazing and furious.

In this slow and silent waiting, another day and a night passed.

When the last trace of furious energy in the demon core was absorbed by the Vermilion Bird Burning Sky Thunder, the demon core shell was completely annihilated and disappeared, and only a crimson thunder was surging in mid-air.

At this time, the Suzaku Burning Sky Thunder did not have the vanity of the past, but had a thunder flame like a substance.

In terms of momentum, it is more powerful than the thunder that generally relies on strong fighting spirit to catalyze!

The growth of Xuan Lei has four stages: juvenile period, growth period, maturity period, and peak period, if the previous Vermilion Bird Burning Sky Thunder was just a prototype of the thunder source, then now it can really be regarded as a juvenile stage, and it initially shows the edge of Xuan Lei!

Mo Yu was now confident that with the help of the Vermilion Bird Burning Sky Thunder, even if he didn't break through the fighters at the moment, some low-level fighters would not be his opponents.

It took two days to devour the two demon cores, and now it's time to break through the fighter!

Staring at Xuan Lei who had grown in mid-air and took a big step, Mo Yu's eyes showed a touch of heat.

With a wave of one hand, Xuan Lei seemed to have received some kind of summoning and flew into Mo Yu's body.

As soon as the Vermilion Bird Burning Sky Thunder entered the body, a strong fiery and numb meaning spread in the body, and after a while, a violent pure energy rushed directly into the body, and suddenly, Mo Yu's body trembled violently.

His face was calm, Mo Yu's hands quickly formed a handprint to absorb the Dou Qi, his breathing gradually became stable, and the faint Dou Qi in his body moved in response to his heart, quickly entangled with the powerful pure energy, and then began to refine frantically.

In the small cave, the calm air suddenly fluctuated violently, and a trace of pale silver fighting qi seeped out of the air, and then continuously drilled into Mo Yu's body.

In the body, the Dou Qi was wrapped in a mass of furious pure energy, and with the crazy refining, there was constantly red energy being assimilated into pale silver Dou Qi, and with the support of these rear forces, the scale of the Dou Qi in Mo Yu's body was constantly expanding at a speed visible to the naked eye.

Although the furious and pure energy was constantly refined, they seemed to be endless, and every time the Dou Qi refined a ball of medicinal power, there would be a greater cloud of red energy rushing over.

The refining continued, until the follow-up force of the berserk energy began to weaken, and at this time, Mo Yu's body had expanded to a critical point that could no longer be increased.

"Condense the Dou Cyclone!"

Taking a deep breath, Mo Yu's handprint suddenly changed, the index thumb was crossed, the middle finger was pointed at each other, and the ten fingers formed a strange handprint.

With the experience of his previous life, Mo Yu is no stranger to breaking through the realm, so now that he uses it again, he is also handy, and there is no sense of jerkiness.

With the change of Mo Yu's handprint, the surging fighting qi in his body seemed to be subjected to a violent suction, and it contracted rapidly towards the position of the lower abdomen.

The pale silver Dou Qi in the veins of the body all began to retreat invariably, and when all the Dou Qi shrank to the lower abdomen, the pale silver Dou Qi had already begun to turn into a silver-white color.

Although the power of resistance is not weak, although Mo Yu's soul perception has declined by more than half now, it is still not inferior to the ordinary big fighter, so the protest of the fighting spirit is undoubtedly a mantis arm blocking the car, but after a stalemate for a moment, it began to shrink rapidly.

When the fighting qi contracted to the size of a palm, it froze again.

The next moment, Mo Yu's eyes were tightly closed, and the soul perception that surrounded the silver-white fighting qi suddenly opened to the maximum, and then squeezed down fiercely!

"Bang!"

A soft muffled sound quietly sounded in the body.

As the muffled sound sounded, the corners of Mo Yu's mouth couldn't help but show a smile.

"Breakthrough, fighter!"
