Gu Feng was sitting cross-legged at the moment, and in front of him, the three Yin Souls were the incarnation of the Great Perfection Yin Soul that he had just captured.

Su Jun and the others naturally didn't know that Gu Feng's artistic conception had already become small, and it was naturally extremely easy to deal with these yin spirits.

Next, in Gu Feng's mind, the mantra for extracting soul power introduced in the "Nine Souls Shaping Demon Skill" appeared!

According to the "Nine Souls Demon Shaping Skill", there are two ways to practice the natal demon soul.

The first is to perceive oneself and condense it with one's own thoughts.

The second is to use external forces to extract pure soul power from the yin soul, fuse their own divine thoughts, and condense the natal demon soul.

If there are enough Yin Spirits, the second method of cultivation will obviously be much faster than the first.

But the problem is that in each Yin Soul, there is too little pure soul power, and the number of Yin Souls needed is too large, although the Ancient Demon Hall is a demon cultivator, it is a true demon, not an evil demon, and it will not kill innocents indiscriminately, so where will there be so many Yin Souls.

This second method, for a long time, has not been used by many people, until the Ancestor discovered this Yin Ghost Ruins.

Here, it is simply a place tailored for the martial artists of the Ancient Demon Palace.

"Extract!"

Gu Feng opened his mouth, ran the exercise mantra, and with a wave of his hand, the translucent soul power of the three soul souls was extracted from the three soul powers, looking at the three soul powers, Gu Feng couldn't help but smile bitterly: "To condense a natal demon soul, these are far from enough!"

Immediately, Gu Feng took out a soul bottle and threw three essence soul powers into it to put it away.

And after these three incarnations of the Great Perfection soul power were extracted, there was still residual soul power left.

These soul powers are not pure, and they cannot condense the natal demon soul, but Gu Feng's eyes lit up.

He remembered the three divine powers of the Heavenly Soul Sect, the soul mist, the soul lock, and the spirit ghost that his father had left for him in the Soul Return Forest.

Now that the spirit soul power has been extracted, and there is no Earth Yin Ghost Bead, it is impossible to condense high-grade spirit ghosts, so Gu Feng gave up refining spirit ghosts.

However, these Yin souls after extracting the soul power of the essence are used to condense the soul mist and soul lock, which is good.

"Let's condense the soul mist!"

Gu Feng thought about it, and then with a wave of his hand, these three souls were entangled and collapsed, turning into a small piece of black mist.

This soul mist, Gu Feng just let it float beside him.

At this moment, Su Jun, Mo Ran, and Zi Yan also each captured the Yin Soul of the Yuan Shen Realm and began to cultivate.

In the blink of an eye, a month has passed.

Outside of Gu Feng's body, the soul mist was already extremely thick, and in that soul bottle, there were already twenty-three soul powers.

In a month, Gu Feng found twenty-three incarnation realm yin souls in this dojo, and extracted the soul power of the essence and soul realm, and Gu Feng naturally would not extract the yin souls of the Yuan God Realm.

To condense a natal demon soul, if you only use the Yin Soul of the Incarnation Realm, you need a thousand Dao, which is obviously far from enough.

Gu Feng's divine soul power swept over, feeling the breath in this dojo, and then spoke: "It's almost, it's time to change places!"

Because Gu Feng had been unable to detect the aura of the Yin Soul of the Incarnation Realm, there was no point in continuing to cultivate here.

The harvest of Su Jun and the others was obviously far inferior to Gu Feng.

Su Jun couldn't help but speak: "Uncle Feng, we are just familiar with this place, and it has become easier to capture the Yin Spirit, why do you want to change places?"

"There are no more incarnation realm ghosts here!"

Gu Feng said lightly.

When Su Jun heard this, he frowned slightly.

He knew that Feng Rei's spiritual cultivation was similar to his, and he didn't even notice it, how could Feng Rey detect it.

Gu Feng saw the doubt in Su Jun's eyes, and said indifferently: "I said, everything needs to be listened to here by me, if you don't want to listen, you can go alone!"

Su Jun's face immediately turned ugly, let him go by himself, how dare he, if he was really unlucky to meet a yin-eyed ghost king, he didn't know how to die.

Mo Ran was here, but his eyes rolled, and he immediately smiled and said: "Mo Ran obeys what Uncle Feng said!"

"Let's go!"

Gu Feng waved his hand lightly, and immediately the isolation formation around him dispersed, and then walked towards the outside of the dojo.

"Uncle Feng, wait for me!"

Zi Yan did not hesitate and immediately followed.

Mo Ran also immediately followed.

Su Jun finally gave up his persistence and kept up with Gu Feng.

Also after Gu Feng and the others left, less than a hundred breaths.

The young man and the young woman, as well as Bing Lao and the others, came here.

"This is really a good place, there are Yin Souls everywhere, after these Yin Souls are captured, they are used to condense the sword soul, and the power of my flying sword can be greatly increased!"

Ximen Lei looked at the white jade flying sword in his hand, with joy on his face.

Among his sect, there are not so many Yin Souls, and when he came today, there were Yin Spirits everywhere, which was definitely a huge creation for him.

In his sect's exercises, the more Yin Souls are poured into the flying swords he cultivates, the better, and these Yin Souls will slowly transform into sword souls, making the flying swords spiritual, so that the level is improved and the power is enhanced.

Beside him, Yan Yu'er spoke: "Brother Lei, this time, our harvest is not small!"

In her hand, she is also holding a flying sword, this flying sword is made of green wood, and the lines on it are clear, with a good atmosphere.

"Bing Lao, how about it, I said there is no danger here, not only is there no danger, but there is such a big opportunity, this time it can help everyone improve the level of the flying sword collectively, this is an opportunity for each of you, and this opportunity can be thanks to this!"

Ximen Lei looked at Bing Lao and the others, and immediately said arrogantly.

"Thank you, young master!"

"This time thanks to the young master!"

"The young master is wise!"

......

The twelve Earth Yin Realm martial artists spoke one after another for a while.

Bing Lao also couldn't help but smile: "The young master is wise!"

He also felt that he was a little worried.

"Young master, someone has been here!"

At this moment, the voice of the old man on the side suddenly came.

As soon as these words came out, everyone's eyes immediately changed.

This ruin is obviously left behind after a sect called the Necromantic Sect was destroyed, it seems that it has been an unknown number of years, how can anyone have come.

Ximen Lei's gaze changed, and he spoke: "Nonsense!"

"Young master, the old man is not talking nonsense, you see!"

Feng Lao pointed to the stones that had been infused with demonic qi scattered by Gu Feng above the ground, and spoke.

Gu Feng also didn't expect that in addition to the Ancient Demon Palace, there were also outsiders coming, after all, here, the Ancient Demon Hall had been discovered for an unknown amount of time, and no outsiders had ever come, so they did not take back these stones.

But I don't want to, at this moment, people have found traces.

When Simon Lei saw this stone, his eyes changed: "This is ......"

Bing Lao's eyes deepened: "This demonic qi should have just been poured into it, looking at the location of these stones scattered, it should be a high-level isolation formation, and the person who can arrange this kind of formation can cultivate at least half a step of earth yin, and this person is a demon sect martial artist!"
