"Comfortable."
Gu Yuan felt the warm current in his body surging constantly, his whole body was as if immersed in a hot spring, flesh and blood and skin were strengthening rapidly at a speed visible to the naked eye.
Every inch of skin on his body has become extremely tough, and the strength has risen by a lot.
If it is daily penance, it is impossible to produce such a change without a few months of practice, but with the help of dozens of magic core energy, it is completed in an instant.
It can be said that the energy of these magic cores helped him save a lot of penance time.
Boom!
Originally, Gu Yuan's cultivation had reached the late stage of the Leather Refining Realm, but now he was assisted by dozens of magic nuclei's essence and blood energy, which helped him break through all at once.
The Leather Refining Realm is complete!
At this moment, Gu Yuan sensed that his cultivation had finally reached the perfect state of the leather refining realm, and every inch of his skin was even the skin of the fragile part.
For example, the fragile skin parts such as eyelids and lips have been strengthened to the greatest extent at this moment, and have reached the point of perfection, without any regrets.
Even if a bullet hits Gu Yuan's eyelids, it is estimated that it will be resisted by his eyelids, like an attack on a copper wall and iron wall, bursting out dazzling sparks.
At the same time, every inch of his skin showed thunder patterns, which spread all over his body.
Vaguely, these thunder patterns are like circuit diagrams, seeming to attract countless currents surging from heaven and earth into the deepest part of his body.
Gu Yuan felt that after countless tiny electric currents poured into his body, like a thunder dragon, he constantly wandered around his body, tempering his physique all the time, making his physique further strengthened.
And his lightning resistance has also been further improved.
This is the mystery of the Demon Thunder Immortal Jue. Once it is successfully cultivated, it can swallow the aura of thunder between the heavens and the earth at all times, tempering the physique all the time, just like the heavenly thunder tempering body.
With the passage of time, the gap between his physique and other warriors will inevitably widen, and it is not comparable to other ordinary warriors, leaving other warriors unmatched.
"The Leather Refining Realm is complete!"
Gu Yuan squeezed his fist, and he felt that his strength had increased by at least 30%. Although it was only a small level, the increase in strength was also amazing.
After being promoted to Consummation in the Leather Refining Realm, not only the body's defenses have been greatly improved, but the body's strength and speed have also been greatly improved, which can be said to be an all-round evolution.
Moreover, if he goes further, he can be promoted to the Bone Tempering Realm, which is also the lowest standard for the inner disciple of the Demon Sha sect.
After reaching this state, it can be regarded as an entry level.
In an instant, Gu Yuan suddenly shot, punching like electricity, and bombarding the nearby rock wall with one punch.
Boom!
Suddenly, the terrifying force of fist smashed the front rock wall in an instant, and was easily pierced like tofu, and a large amount of rubble and dust rolled down.
And his fist was undamaged, even if he suffered such a great counter-shock force, his skin was as tough as cowhide, and it couldn't hurt such skin at all.
Even when punching, it seemed to trigger the thunder pattern on the body's skin, which also made Gu Yuan's speed faster, as if it had assisted an electric current.
Vaguely, there was lightning flashing in the darkness, electric current exploded, and crackling.
Although it is only a phenomenon of static electricity, if you continue to practice in this way, you may be able to master the thunder.
"But what is this place? How come there are so many elite corpses hiding here? No wonder this place is a corpse devil's lair?!"
After consolidating the perfect cultivation base of the Leather Refining Realm a bit, Gu Yuan touched his chin, his eyes showed a gleam, and he suddenly remembered what the elite group of corpse demons had just said.
It seems that I suddenly came to this place and caused this group of elite corpses to jump off, thinking that I had discovered the secret of the other party, the enemy is attacking, and he said something like a king.
Could it be said that a king was born among this group of corpse demons, who can rule many corpse demons? !
If this matter is true, then he has really discovered an incredible secret, maybe the legendary corpse king is in the depths of this tomb.
"By the way, this place must be the base camp of this group of corpse demons. Although I broke into this place by accident, I hit the right side and found the location of the corpse king."
Thinking of this, Gu Yuan's eyes suddenly lit up.
Because if this place is the lair of the corpse king, there is no doubt that this place must be heavily guarded, with countless powerful corpse demons hidden.
If you break into the corpse king's lair, you will definitely be besieged by countless corpse demons, and even the corpse king will be furious and brazenly take action, behead the intruder himself, and divide the body by five horses.
It's done, it's done now!
As long as he is reckless, breaking into the deepest part of the corpse king's lair, and fighting the corpse king here, according to the strength of the corpse king, wouldn't he be able to kill him in minutes? !
At that time, he was dead, and there was no reason to survive.
"Go in."
Gu Yuan immediately made a decision, broke into the corpse king's lair, found the corpse king here, and competed with the corpse king.
After all, the chance of death like this is still very small, and it is not allowed to be missed.
Whoosh!
In an instant, he immediately moved towards the deepest part of the underground tomb.
However, this underground mausoleum is not simple. It has a large area and intertwined rice paddies. It is like a maze. If you are not familiar with it, you will easily lose your way and don't know where to go.
The most important thing is that the more the underground mausoleum, the richer the demonic atmosphere and corpse aura it contains, almost condensed into substance.
If an ordinary warrior stays in such an environment all the time, I am afraid that his body will suffer irreversible damage.
But Gu Yuan was like a fish in water under such an environment. For him, this kind of place was simply a blessed place, a holy place for spiritual cultivation.
He ran the breathing method, instead swallowing the huge world evil spirit and demonic energy, as well as the corpse energy, rapidly increasing the cultivation base.
Therefore, he became more and more energetic, as if he was a monster whose energy could not be exhausted.
"It should be here."
Gu Yuan's perception is extremely keen. Although he doesn't know the map of this underground tomb, he knows that where the monster's aura is stronger, it must be the place where the corpse king is.
Therefore, as long as he moves towards the place where the corpse qi, the devil qi is strongest, he will definitely be able to find the base camp of the corpse king.
He crossed the passages of the underground mausoleums, and he didn't know how many kilometers he had walked. He felt that he was getting closer and closer to the place where the demon's aura was strongest.
It is estimated that it will not take long for Gu Yuan to reach that place.
