If the Immortal Stone is the essence of the Immortal Qi condensed in the body of the Immortal Statue, then the Bone Erosion Yin Sui is the essence of the Immortal Stone Energy condensed in the body of the whole ghost.

In other words, the bone-eroding yin is the essence of the essence.

This energy is very amazing.

But this bone-eroding Yin Sui energy is different from those elixirs refined from dark stones, and it cannot be cultivated selectively.

In other words, if Li Xian was to cultivate, he must cultivate both the ghost control technique and the Yuan Soul Body.

Moreover, the vast majority of the energy has been used to practice ghost control techniques.

I was afraid that the Secret Gate Master's bone-eroding Yin Sui would be exhausted, and Li Xian's Yuan Soul Body would be difficult to break through to the early stage of the Nine Palaces.

At the moment, he couldn't care about so much, and Li Xian immediately activated the golden ghost bead that was integrated with his body.

Suddenly, the Bone Erosion Yin Sui vaporized at an extremely fast speed, and along Li Xian's arm, it poured into his dantian, and then formed a small whirlwind, which was transformed into golden gas and entered the Ghost King space.

In the Ghost King space, the illusory golden dragon sealed the territory on the golden ground.

The depth of the ghost king's space is constantly increasing.

1,591,100 km away!

1,591,200 km away!

1,591,300 km away!

……

If it had been before, this cultivation speed would have remained the same. But for the current Li Xian, it is really too slow to mention.

Especially when I think about it, these are still cultivated with the essence of the essence, the Bone Erosion Yin Sui, which is really a bit of a tyrannical thing.

Li Xian's Yuan Soul body also slowly improved at an extremely slow speed.

A few times, Li Xian wanted to stop cultivating first, but as soon as he paused slightly, the secret door master began to struggle violently, and even almost threw him out.

After a period of bone-eating pain, the Secret Gate Master was already a little numb from the pain, so the strength of her counterattack was gradually increasing.

Li Xian is now advancing and retreating, if he doesn't take away the Secret Gate Master's Bone-Eroding Yin Sui cultivation, or if he slows down his cultivation, the Secret Gate Master will fight back; If he cultivates too fast and exhausts the Bone Erosion Yin Sui, the Secret Gate Master will be completely free from the pain, and if Li Xian can't be instantaneous, he will also be controlled by her.

Of course, once she loses the Bone Erosion Yin Sui, then the Secret Gate Master will lose her continuous eternal power, and as the top powerhouse of the Underworld, her strength will be greatly reduced.

But even if it is a big drop in strength, it is also a big drop in front of these strong people like the Ten Halls Underworld, for Li Xian, who does not even have the realm of the Ten Palaces, no matter how much his strength drops, it is meaningless, he is still not the opponent of the Secret Gate Master.

In the blink of an eye, one-third of the bone-eroding yin in the main dantian of the secret gate gate had been consumed.

Not only is Li Xian's ghost control technique consuming this energy, but Li Xian's Yuan Soul body is consuming this energy, and even the Dan Soul hiding in the Dantian of the Secret Gate Master is actually taking the opportunity to absorb the energy after the bone erosion Yin Sui gasification.

The owner of the secret door was in despair.

Once she loses the Bone Eclipse Yin Sui, even if one day, she opens the Cloud Seal Heavenly Book, the possibility of her becoming the Lord of the Underworld is very small.

When she was finally able to speak, she begged: "Li Xian, let me go, let me go, in the future, I will be yours, deputy, I, help you, be, the king of the underworld——"

Li Xian is not stupid, knowing that this is her right and interest.

She became the new master of the medium, took away the clairvoyant pupil, and never even returned the Cloud Seal Heavenly Book to her, for her, these were just things outside her body. But she ruined her bone-eating yin, which is equivalent to ruining her maverick's biggest advantage, and she will never let go of herself again.

Letting go now is the same as letting go after her bone-eating flint has been exhausted.

Rather than that, it's better to choose the latter.

Choosing the latter, if a miracle appears and the cultivation reaches the early stage of the Nine Palaces, the extra few seconds will be enough for him to escape. Moreover, in the future, he became a ghost in the Ten Palaces, and there was one less such super strong person as an opponent.

Even if there is no miracle, it is nothing more than the same torture that she suffered, or the same anger of her, and she was eliminated on the spot.

"I'm sorry, I can't stop." Li Xian said deliberately.

He kept cultivating.

The depth of the ghost king's space is 1,592,900 kilometers!

The Yuan Soul Body is also close to the realm of the middle stage of the Eight Palaces.

However, at this time, the bone erosion is less than one-third.

"I only hate, I, I am too careless to you!" The master of the secret door gritted his teeth.

At this time, she had no power to resist.

Li Xian didn't pay attention to her, he wanted to come up with a strategy to escape from the master of the secret door after the bone-eroding yin was exhausted.

Li Xian stretched out his left hand while cultivating.

On the palm of his left hand, a samadhi fire suddenly appeared.

He pressed the palm of his hand that was bubbling with the true fire of Samadhi on the body of the master of the secret door.

The master of the secret door has sensed that the remaining bit of bone erosion is no longer a climate, and it is not of much use to keep it, so he no longer asks Li Xian.

She sneered and looked at Li Xian: "Boy, with your samadhi true fire, do you want to burn me too?" ”

Li Xian's samadhi fire burned on the arm of the secret door master, but her arm was like a stone, and it couldn't leave any wounds.

His strength was suppressed so much in the Eight Palaces that he didn't break through to the realm of the Nine Palaces, and in such an environment, he couldn't even fly, let alone other ghost arts.

Even if he used his heart to control the sword of the ghost king, he could only leave shallow traces on the body of the master of the secret door.

"Meng Jiang, what should I do next?" In a hurry, Li Xian had no choice but to ask Meng Jiang again.

Although Meng Jiang is knowledgeable, his combat effectiveness is average, not to mention that he has much combat experience.

Faced with such a situation, she was also at a loss.

Xue Ling, who has been practicing in the Origin Spirit Nest, and Da Ling'er, who has been bored and had to stay in the Yuan Spirit Nest all day after being separated from the little villain, also flew out and chirped to give advice to Li Xian, but they were all worthless.

Ouyang Ting, who was extremely tired, had been sleeping heavily, but even if she woke up, she must have no combat experience, so she could only be at a loss.

"What about the Dan soul you refined?" Meng Jiang hesitated for a moment and said, "If you really have no choice, if you try to swallow it alive, there may be a miracle, but I'm not sure, anyway, it's better to try it than to fall directly into the hands of the secret door master!" ”

"Huh? That Dan soul has already become a spirit? When Da Ling'er heard Meng Jiang's suggestion, she inevitably felt sad about the death of a rabbit and a fox, and reached out and touched her neck, "Okay, so cruel!" ”

As he spoke, the bone-eroding yin in the main dantian of the secret gate was instantly exhausted.

At this time, the depth of Li Xian's ghost king's space is 1,593,500 kilometers! And his Yuan Soul Body had just reached the realm of the middle stage of the Eight Palaces.

"Hahaha......" The secret door master laughed triumphantly.

But it will take a few more seconds for her to recover.

Li Xian still couldn't fly and teleport in the Eighth Hall, and when Li Xian's right hand was pulled out of the stomach of the Secret Gate Master, the white-bearded and white-haired Dan Soul also flew out.

"Open your mouth!" Dan Soul actually called out these two words clearly, and at the same time, it crashed headlong into Li Xian's unclosed mouth.
