Inside the cave.

The flames are rising, and the temperature is extremely high.

At this time, Yang Yifan had already started the refining of the Demon Extreme Pill and the refining of the fourth-level elixir, which was the first time for him, so he was extremely cautious in every step, even the first refining of the elixir into spiritual liquid, it took more than ten hours.

"Whew~"

After refining all the seven elixirs into spiritual liquid, Yang Yifan slowly breathed a sigh of relief, relaxed his mind, took out a Qi Returning Pill and stuffed it into his mouth, and slowly recovered his true qi.

The refining of the fourth-level pill was very difficult, and the materials were so rare, Yang Yifan didn't look like a waste, so he planned to use the peak state at every step to improve the success rate.

……

Time passed quickly, and after a day and a night, there was a sudden rumbling sound in the cave.

If someone appeared in the cave at this moment, they would definitely be shocked by the scene in front of them and speechless.

At this moment, the entire cave had already been filled with surging aura, and countless auras were frantically instilled into Hei Yanding, and its concentration caused even the air to distort slightly, looking as if it was in an illusion.

"Condensation!"

Just when the aura between heaven and earth was surging wildly, Yang Yifan suddenly opened his eyes, his tongue bloomed with spring thunder, and he suddenly let out a loud roar!

Swish!

As this word fell, the aura that was circling wildly around suddenly slammed down, and then, it was instilled into the Black Flame Ding at a speed that was several times faster than before!

"Boom!"

With such a huge amount of aura poured in, Black Flame Ding made a rumbling sound, this sound was like a Monkey King locked in it, jumping up and down, and hitting the Ding Wall crazily!

"Huh!"

After a full ten minutes, the sound of rolling thunder in the Black Flame Ding finally disappeared, and the trembling body slowly calmed down, seeing this scene, Yang Yifan's face was full of excitement, and he stood up suddenly, and couldn't wait to open the Black Flame Ding!

"Whoosh!"

With a burst of fragrant fragrance coming to his face, a sound of breaking the air suddenly sounded, Yang Yifan's eyes were quick, and he quickly took out a jade box, and directly put the elixir that came out into the jade box!

"Demon Extreme Pill!"

Looking at the black and white elixir in the crystal clear jade box, Yang Yifan looked up to the sky and roared!

Success, success!

Even Yang Yifan himself didn't expect that he had really refined a fourth-level elixir, the Demon Extreme Pill!

This is not the key, the most important thing is that because of the obsession in Yang Yifan's heart, the quality of this pill is extremely high, although it does not reach the top grade, but it is also a shocking top grade!

"Good! Good! Without further ado, swallow it now! ”

Yang Yifan laughed, and then, he first fed the Kurosawa python a spirit again, then sat cross-legged on the ground, and did not hesitate to take out the Demon Extreme Pill and swallow it!

"Boom!"

When the Demon Extreme Pill entered his abdomen, Yang Yifan felt a strong pain, as if a raging flame was burning in his body, and it was like a thousand knives, fried in a boiling oil pot!

"Ahh

Under such intense pain, Rao is Yang Yifan has a great mind, and he couldn't help screaming at this time, but he didn't lose his mind, at this critical moment, the screaming stopped abruptly, he gritted his teeth fiercely, the green tendons on his forehead were exposed, his face was red, and his eyes were full of ruthlessness!

"Give me refining!"

With a roar, Yang Yifan frantically urged the true qi in his body, only to hear the boom, a violent true qi fluctuation suddenly emanated from his body, hovering around, surging wildly!

"Boom!"

Under Yang Yifan's desperate refining, his body was like a traveler who had been thirsty in the desert for a few days seeing water, desperately absorbing it, and his physical strength was even more crazy under this kind of violent energy!

……

An hour......

Three hours......

Five hours......

Ten hours!

In these ten hours, Yang Yifan wailed for five hours, and the more he went to the back, the more intense the pain he endured, and in the end, his throat was already hoarse!

And under such pain, the benefits Yang Yifan has obtained are simply amazing!

"Huh!"

Finally, the screams disappeared, Yang Yifan slowly stood up, at this moment he was covered with sweat, as if he had been fished out of the water, and his face was even more tired and afraid that could not be concealed, but his eyes were flashing with a trembling essence!

"Crunch, squeak!"

Clenched his fists, Yang Yifan felt the powerful power surging wildly in his body, slowly closed his eyes, and showed a hint of intoxication on his face.

That's what power feels like, that's what power feels like!

It's so strong! It's so cool!

At this moment, all the injuries in Yang Yifan's body had completely disappeared, and under the medicinal effect of this Demon Extreme Pill, he had been directly promoted to the realm of the seventh layer of foundation building, and even the Nine Transformations of the Divine Dragon had reached the ninth transformation!

It is no exaggeration to say that at this time, Yang Yifan's physical body is stronger than the demon beasts of the same level, I don't know how many times, it is extremely terrifying!

"But ......"

Yang Yifan suddenly frowned.

The Nine Transformations of the Divine Dragon have reached the ninth transformation, and it stands to reason that he should have cultivated to the extreme, but at this moment, he has a strange feeling in his heart, as if he has just spied on the door of the Nine Transformations of the Divine Dragon, as if there are still too many secrets of this exercise waiting to be explored!

Could it be that there is a follow-up to this Nine Transformations of the Divine Dragon?

Thinking of this, Yang Yifan was not calm at that time!

You must know that at this time, the Nine Transformations of the Divine Dragon have been able to increase the strength of the physical body by nine times, and it can already be called a divine skill, if there is a follow-up...... How strong should that be?

I can't imagine!

"Boom!"

Just as Yang Yifan was thinking, a roar of true qi brought him back to his senses, he turned his head and looked to the side, only to see that the momentum on the body of the black python that was coiled together suddenly increased by more than ten times, obviously a breakthrough!

Breakthrough again?!

Yang Yifan was surprised and delighted.

The good thing is that Kurosawa Python can break through, which is naturally a good thing for him.

I was amazed...... He seems to have forgotten that in the past two days, he seems to have given the bag to Kurosawa Python, and all the essence was eaten by it!

Sixteen spirits!

The entire sixteen essences only allowed the Kurosawa Python to improve one realm!

"It seems that before leaving this Demon Soul Valley, we have to rob it well, if not, the number of this spirit is not enough!"

Yang Yifan muttered to himself, and the corners of his mouth hooked up with a sneer.

Wang Heihu? Green lotus seeds? Zhou Kai?

Hehe, in the past two days, you guys should have had a good harvest!

Next, honestly hand over all the spirit in your hand to me!

"Boom!"

With a big hand, the door of the cave opened, and Yang Yifan strode out! ()
