Chu Zheng couldn't understand this question, and he couldn't help but sit down and began to check the many Qiankun talismans he received. He wanted to find another book on soul cultivation to find out what was going on. After all, there was no record of the soul space in the exercises such as the "Demon Spirit Nine Turning Techniques" that he had learned before.

He found a copy of the Soul Strengthening Formula. It's a pity that this exercise doesn't talk about the inner view of the soul space at all, it's just a superficial exercise. However, Chu Zheng still got useful information: Cultivating the spirit pill can strengthen the soul.

Chu Zheng found a few spirit pills from those Qiankun talismans and took them.

Bursts of heat flowed into the soul space, and the slightest mist seeped into the space wall and was absorbed by the space wall.

"It seems like my space wall has grown a little bigger. Chu Zheng made a discovery.

He looked at the sun and moon hanging in the sky, and suddenly remembered that they were shining brightly and stinging himself just now, and he couldn't help but think about it, wanting to urge the sun and moon, but the sun and moon didn't seem to be able to be urged by him, so he could only passively exert his power, Chu Zheng tried for a long time, and the sun and moon radiated a burst of light, shining on Chu Zheng's soul space wall.

A burning pain came, and Chu Zheng only felt that the demon yuan in the Yuan Wheel was frantically extracted, transmitted to the Sun Wheel and the Moon Wheel, and then turned into light and shone out.

Although it was painful, Chu Zheng could bear it, he condensed his spirit and looked inward, only to see that the space wall seemed to be constantly absorbing under the illumination of light, and the originally dark space wall began to gradually have a luster. But only a little.

"It turns out that my soul can cultivate like this. Chu Zheng gritted his teeth, and when his demon yuan was exhausted, the pain was not as strong as before.

When Chu Zheng looked inward again, he found a few drops of crystal liquid, "Where did this liquid come from?" He tried to sense it, it seemed to be a very pure soul energy.

Soul energy can be condensed into liquid, just like the magic liquid. Chu Zheng guessed that now, he urgently needed a book on soul cultivation, and he was becoming more and more interested in exploring the secrets of the soul.

For three days in a row, Chu Zheng used the light of the sun and moon to exercise the soul space wall, until he felt that the soul space wall seemed to be more condensed, and then he walked forward.

There were constantly corpses jumping up and pounced on themselves, but they were all killed by Chu Zheng, and those green mist clouds entered Chu Zheng's soul space and were refined into soul liquid.

Constantly cultivating like this, Chu Zheng only felt that the power of his spiritual sense was getting stronger and stronger.

Constantly absorbing the mist, constantly slashing the green demon, and constantly using the light of the sun and the moon to exercise the soul space wall, in the end, Chu Zheng's soul space wall actually became radiant, and it was no longer pitch black.

And the soul essence liquid in the space has also been spread all over the ground.

Just when Chu Zheng was satisfied, a cold laugh rang out:

"Hey, hey, hey, I didn't think that after so many years, there was finally a person with a qualified soul. It's not in vain that I've been waiting for so many years to die. ”

Chu Zheng's whole body was cold and his hair stood on end, he never imagined that there would be a sound in the empty and uninhabited hall.

A green light flashed away, yes, it was a green light, Chu Zheng ran the Rigang trick and defended with all his might.

But seeing that green light flying around it, let Chu Zheng swing his sword and slash, but he couldn't hurt it in the slightest, but he couldn't stop laughing and laughing: "Okay, this body is really good." ”

"Snatch away?" Chu Zheng said in his heart.

"Who are you?" he asked, keeping his guard on the line.

"Who am I? I've almost forgotten who I am, who am I? How long have I lived? I've been trapped in this palace for millions of years, and who am I, who am I?" the green light stopped, as if thinking.

At this time, Chu Zheng saw clearly that the green light turned out to be humanoid.

Chu Zheng's heart tightened, he had already worked hard to absorb those green mist and green shadows before, this green light was obviously much more powerful than those green shadows, and it was humanoid, could speak, and had spiritual intelligence, and said that he had been in this palace for millions of years alone.

An old monster who has lived for millions of years? Chu Zheng felt an unprecedented crisis.

He stuffed a demon blood clot into his mouth, this demon blood clot was enough for him to use many times to recover the demon element, but Chu Zheng was clear about the crisis in front of him, and this crisis would never be easy to get by.

"Good, good. The green light said yes in a loud voice, and the last sprint entered Chu Zheng's soul space.

Chu Zheng's soul space was already dazzling, and when the green light came in, he was a little caught off guard, and exclaimed: "Sun and Moon Spirit!" But this green light quickly calmed down, and secretly rejoiced: "Fortunately, this kid's cultivation years are negligible, otherwise with this Sun and Moon Spirit alone, I would definitely die here today." ”

Calming down, the green light began to smash the soul space wall violently.

Chu Zheng felt a sharp pain coming, this kind of impact from the soul he didn't know how to protect at all. The light of the sun and moon evaporated and absorbed the green mist of the green man, but it did not cause fatal damage.

"The rate of absorption is too slow. Chu Zheng found this in pain.

And that little green man was a dragon spirit and a tiger, attacking Chu Zheng's soul space wall like crazy.

Chu Zheng seemed to feel that the soul space wall was about to crack.

He violently urged the sun wheel and the moon wheel, and the two light voraxes approached downward, sucking violently, and the little green man's movements seemed to be slower, but still heavy and powerful.

Chu Zheng was anxious, the strength of this little green man was far beyond his imagination, he was really afraid that the little green man would shatter his soul space wall in the next moment, and at that moment he quickly took out a moon spirit flower from the Heavenly Cave Mansion, and with a ruthless heart, the whole plant was subdued.

A coolness spread throughout his body, and Chu Zheng sobered up a little. The essence of the Moon Spirit Grass rushed into the soul space, and actually began to make up for the scars on the soul space wall, Chu Zheng was overjoyed: "It has an effect." ”

He quickly took out a Sun God Flower from the Heavenly Cave Mansion and swallowed it.

The surging sunlight was extremely intense, scorching the little green man's heart, but he was still very violent, and he chose a place on the wall of Chu Zheng's soul space and constantly smashed it.

The medicinal power of the Sun God Flower and the Moon Spirit Grass was surging in the soul space, forming a cyclone, which was also depriving the little green man of his green light. He's noticeably smaller.

But Chu Zheng's soul space wall also had a crack, and after a while, I am afraid that this soul space wall will be smashed or smashed through by him.

Chu Zheng really felt the crisis, he couldn't care about it anymore, and suddenly, he urged the red magic bead in the first demon yuan wheel, and the red mist rushed up and rushed into the soul space.

"Ahh Obviously, the demonic mist that snatched the Yuan Zhu hurt him heavily.

"Effective!" Chu Zheng was overjoyed, and continued to urge the Yuan Mist, the little green man rolled on the ground in pain, and he couldn't care about destroying Chu Zheng's soul space wall anymore.

"Spare your life, spare your life!" cried the little green man.

But how could Chu Zheng spare him, refining him through the light swirl formed by the sun and moonlight, and hurting him by seizing the Yuan Mist.

The mist seemed to make it impossible for the little green man to move freely, and gradually, he was absorbed by the two swirls of light until only a cloud of mist remained.

"Little brother, spare your life. I've been trapped here for millions of years, and I've finally seen the light of day, you can't let me die, I know a lot of secret places and treasures. The green figure said hoarsely.

Chu Zheng was a little moved, retracted the Yuan Capture Mist, and stopped the sun and moon light swirling.

The miserly figure looked miserable, and looked extremely weak.

"God have mercy on me, for millions of years, I've been reduced to this point. The green shadow cried.

"It's amazing, it's all a mist and you can still talk. Chu Zheng was secretly frightened.

"Who are you, why did you take away me?" Chu Zheng said.

"A lonely ghost who has been trapped for countless years, of course, he wants to take it away and survive. Poor old monsters like me have been reduced to such a state. The green shadow cried.

"How can I trust you?" Chu Zheng said.

"You don't have to trust him, I have the means. ”

Suddenly, another voice in the hall said lightly.

Chu Zheng expelled the spirit and fought a cold war, there are still old monsters in this hall?
