With the blind box system in hand, the waste material counterattacks and becomes a genius in cultiva

Soon, Niu Feng closed his eyes again and guarded with all his heart!

Although he was curious, Xiao Chen was currently in seclusion and could not be disturbed, so he naturally would not go in to ask!

Of course, when Xiao Chen comes out of seclusion, he will definitely go and inquire.

After all, this demonic energy is too shocking. It is rare for human beings to absorb demonic energy in this way during cultivation, which is really exaggerated!

Inside the house!

The green crystal stone was suspended in front of Xiao Chen, emitting an astonishing demonic aura. It was surrounded by a green mist, which was extremely dense and slowly evaporated, looking extremely strange!

The demonic energy was extracted, and a green beam of light as thick as a thumb shot into Xiao Chen's brow at a terrifying speed like lightning. The vast demonic energy entered Xiao Chen's body like waves, flowing along his brow, into his whole body, and through his limbs and bones!

"The demonic energy contained in this demon core is so violent that even my martial god body can't withstand it. My flesh and blood are almost cracked!" A look of pain appeared on Xiao Chen's face.

His black hair was flying and his body was as strong as iron, but at this moment it was constantly expanding and erupting with an extremely unstable energy wave!

Wrapped in the green light mist, Xiao Chen's entire body was illuminated by a dark green hue. The originally handsome and extraordinary young man, at this moment, looked a little weird, like a netherworld creature that walked out of the underworld!

Suddenly, a green demonic light shot up from Xiao Chen's forehead, about to penetrate the roof and rush straight into the sky!

This was because the demonic power that was poured into Xiao Chen's body was too terrifying, and Xiao Chen was unable to absorb it for a while, and it broke out of his body uncontrollably!

Xiao Chen suddenly became anxious. If the demonic light pierced the sky directly, the noise would be too loud and would definitely cause a stir in the Taixu Sect.

By then, the secret that he can directly devour the power of the demon core will be exposed to the public. That would be too shocking, and things would get completely out of control!

He didn't want to reveal the secret, because this ability was unprecedented in history, he was the only one with it, and it was too incredible!

Even if the trees are beautiful in the forest, the wind will destroy them!

He is still too weak and needs to lie dormant!

Just when he didn't know what to do, the system took action!

Almost instantly, light black ripples appeared around Xiao Chen. The ripples spread rapidly, diffusing to the surroundings at an incredible speed, directly enveloping the entire room where Xiao Chen was, forming an almost transparent barrier, lightly covering the green evil spirit that was about to rise into the sky!

Soon, the evil spirit condensed on the roof encountered the barrier and collided slightly. After a series of sizzling sounds, the evil spirit blocked by the barrier slowly dissipated!

"Fortunately, it was blocked!" Seeing this, Xiao Chen breathed a sigh of relief.

If this evil spirit really rises into the sky, it might attract some old monster to come and he might be captured and used as an experimental subject for research!

But after a moment of relaxation, his expression twisted again.

The demonic power released by the demon core was too terrifying, constantly impacting his body, causing severe pain, as if thousands of blades were hitting him, extremely painful!

His handsome face was distorted, his facial features squeezed together, his white clothes had long been shattered by the evil spirit, and now only a few pieces of cloth were left covering his body. His long black hair was also wet with sweat, and a few strands of hair were wetly hanging on his forehead!

"Damn it! It's been so long, and the severe pain in my body hasn't subsided!" He muttered to himself, his voice trembling with pain.

Fortunately, this unbearable pain did not last long.

Gradually.

Xiao Chen's expression returned to normal, and the violent energy fluctuations around him also stabilized!

The demon core, which contained tremendous demonic power, was suspended in the air, trembling slightly, still emitting a gorgeous green light.

The demonic power poured out in the shape of a green beam, sinking into Xiao Chen's brows and continuously impacting Xiao Chen's body!

But Xiao Chen's body no longer shook or trembled, but was as steady as a mountain!

His body began to heat up, like a blazing furnace. The spiritual fire in his body had been ignited and was now constantly tempering his body, making his body more perfect and his energy more pure!

Gradually, the pain caused by the raging demon energy completely disappeared, and was replaced by a warm and comfortable feeling flowing through the whole body!

In the void, the soul of the three-headed demon wolf became increasingly dim. At first, it could still wail, but later, it lay motionless in the demon core like a dead dog, waiting to die!

"Finally got used to it, now let's start speeding up!" Xiao Chen said to himself with a smile.

As his mind moved, the green light beam that shot out from the core of the three-headed demon wolf suddenly became about an inch thicker, and the energy flowing into Xiao Chen's body became more and more turbulent. Xiao Chen's physique and energy increased greatly!

Not long after, the demon core of the three-headed wolf demon was sucked into white, turned into waste stone, and fell to the ground!

The energy in the core of a great demon at the general level was exhausted just like that!

If other practitioners saw this scene, they would definitely be shocked!

Xiao Chen's absorption speed is too terrifying!

Even if a general wants to absorb the demon core of a great demon at the general level, it will take at least a month, and that is the kind that has been purified and lost most of the demon essence!

But what Xiao Chen absorbed was an unpurified demon core. Not only did he not explode and die, but he also sucked up the entire demon core in such a short time. It was simply horrifying!

"I absorbed so much energy, but I didn't even break through a realm! The energy I need to break through is much more than that of practitioners at the same realm!" Xiao Chen sighed lightly, feeling a little painful.

But he soon took out another demon core and began to absorb it. This time it was the demon core of a six-eyed mantis demon!

Now, Xiao Chen's martial god body has adapted to the impact of the demonic power of the demon core of the general-level demon, and it is much smoother to absorb it!

Like the three-headed demon wolf soul before, the demon soul of the six-eyed mantis demon also bared its fangs and looked extremely ferocious at the beginning!

But when Xiao Chen started to absorb its demonic essence, it immediately realized that something was wrong!

The human insect's physical body in front of him was astonishing, and the speed at which he plundered its demon essence was incredibly fast!

It soon began to beg for mercy!

But Xiao Chen doesn't care about these!

Green demonic power was continuously drawn out from the demon core of the six-eyed mantis demon, gathering and flowing into Xiao Chen's brows!

After absorbing all the demon cores of the six-eyed mantis demon, Xiao Chen's physical body and martial essence were further strengthened, but he still failed to break through!

After Xiao Chen absorbed the demon core energy of two big demons!

Finally broke through!

The aura on his body began to surge!

"It's done, I've reached the eighth level of Sword Master! But the further you advance, the stronger the energy required! I hope these demon cores given by Yin'an will be enough for me to break through to the general realm!" A hint of joy appeared on Xiao Chen's face, but soon, he began to worry about the resources for cultivation!

Originally, according to his estimation!

The demon core given by Yin'an was enough for a breakthrough, but now it seems that it is not safe!

From the seventh level of swordsman to the eighth level of swordsman, the amount of demon cores consumed was more than he expected!

His estimate may not be accurate!

But since he has already started, he naturally cannot stop halfway.

Soon, he took out the demon core again and absorbed it!

Half an hour later, the area under Xiao Chen's bed was littered with white waste stones that had been drained of their demon cores. Xiao Chen's aura was also much stronger than at the beginning. He was as sharp as a newly born divine sword, ready to destroy the heavens and the earth!

"That was close! Fortunately it worked!" Xiao Chen breathed a sigh of relief!

There was almost an accident just now!

After consuming the last demon core, Xiao Chen was still one step away from becoming a half-step sword general. He hurriedly took out the inferior spirit stone given by Gu Lanlan and absorbed it, and only then was he able to barely advance!

The energy he needed to break through was too much, like a bottomless pit, and ordinary people simply couldn't afford it!

Now, he is penniless again!

"Next, start condensing the martial core!" A hint of anticipation flashed in Xiao Chen's eyes!

Just then, there was a noise outside the door!

"Where's Xiao Chen?"

"Senior Brother, Xiao Chen is in seclusion, please wait a moment!"

"Wait? He's just a follower, what right does he have to make me wait? Call him out immediately!"

"Brother, you can't go in!"

"Go away!"

"You're going too far!"

Then, there was a fierce fight!

However, there seemed to be a huge disparity in strength. After a moment, the fighting stopped. Niu Feng let out a muffled groan and fell to the ground!
