This was the first time Li Sui'an had obtained a fifth-order blood crystal.

After refining it, a majestic stream of water essence poured into the kidneys.

Feeling the reaction of a certain part of his body, Li Sui'an's complexion changed slightly, and he immediately chose a secluded beach to start practicing boxing.

In a trance, it was as if a demon tiger with wings was swimming in the sea of thunder, and every time the thunder and lightning hit the demon tiger, it was accompanied by the sound of muscles and bones.

The essence of water is quickly channeled out from the kidneys, circulating through the five organs, starting from the kidney water, ending at the lungs, and then returning to the kidney water, turning into pure life qi and blood flowing throughout the body.

In this way, the five internal organs are endless, and the essence is endless.

As his fist unfolded, the bones of his whole body crackled, and all his internal organs made the sound of tiger and leopard thunder.

The dark energy in the body continued to grow, and began to guide the bones of the whole body over and over again.

A little bit of gray turbidity is squeezed out of the bones, metabolized, and excreted from the pores.

This process of refining the bones of the whole body as a whole can only be regarded as a superficial tempering, and it is impossible to be exhaustive. In the realm of quenching bones, it is more necessary to cooperate with the body refining exercises, focusing on guiding the dark energy, and focusing on refining a certain bone.

Limbs, torso, ribs, and finally the skull, all the way through the bones of the body.

The trunk is the center of the human body, involving countless nerve veins, which cannot be simply refined.

There is no trivial matter in the brain, and every step is dangerous.

When the bones of the whole body are tempered, the bones are like steel, and the flying sword is difficult to hurt.

Just like the original little plum when he faced the corpse king for the first time, he was helpless.

Li Sui'an chose to start with the bones of the limbs.

It is also the safest option.

For the sake of insurance, Li Sui'an grabbed another bone quenching pill, a golden pith pill, and a marrow purifying pill and threw them into his mouth to assist in quenching the bone and washing the marrow.

Dark power surged toward the bones of his left arm.

Normally, a person has 30 bones in each arm, including 1 humerus, 1 ulna and 1 radius, 8 carpal bones, 5 metacarpal bones, and 14 phalanges.

With the fist momentum, the dark energy is channeled to the left arm, constantly refining each bone with precision.

Until the fifth-order blood crystal energy was exhausted, sixteen bones had been tempered in the left arm.

On the attribute panel, the progress bar of the Flesh Secret-Quenching Bone Realm jumped by more than five hundred points.

According to this calculation, only two hundred fifth-order sea beast blood crystals were needed to complete the bone quenching process.

I was in a good mood for a while.

Continue to hunt down monsters along the coast.

until tracing the source of a vein of aura, and finally landing on the top of a black mountain.

The demonic qi in this place is extremely rich, and it is the leading point of a genuine Yin Spirit Vein.

I'm not in a hurry to extract the spiritual vein, just to cultivate.

Li Sui'an took out the magic grass from the storage bag and inserted it into the black soil beside him.

When the demonic grass entered the soil, not only did it erupt its own demonic qi, but the surrounding demonic qi was also gathering rapidly.

Grass roots under the soil are also taking root and sprouting rapidly.

Soon, a large area of tender green grass sprouts grew next to it, and these magic grasses reproduced and spread, and in a short period of time, an entire magic grass field had already formed.

The concentration of the surrounding demonic qi increased by several levels at a speed visible to the naked eye.

Li Sui'an waved his hand and asked the ghost servants to kill.

He cultivated in the center of the demonic qi.

The power of the tenth qi sea in the void above his head was greatly opened, and an endless stream of demonic qi and spiritual qi was absorbed, refined, and quickly filled the qi sea.

In this way, the absorption and conversion efficiency has reached 600%, and it has truly reached the level of the lower grade bone.

Moreover, the demonic qi can also improve the quality of the true qi.

Why not.

It wasn't until it got dark that Li Sui'an stopped practicing.

At this time, the Demon Grass Grassland had spread out of a radius of three miles.

Pulling out the magic grass, the entire grass on the top of the mountain also withered rapidly, turning into a piece of black soil again.

No...... It seems that all the nutrients of this black soil have been drained and completely turned into a scorched earth.

There were still a few large trees around, but they also withered and withered at a speed visible to the naked eye.

As soon as the wind blew, a piece of wind and sand was raised.

For hundreds of years, it will be a barren land, and no new vegetation will be able to grow.

"What a vicious demon grass!"

Fortunately, I didn't bring it to the ghost world.

Li Sui'an's old trick was repeated, and after digging out this small genuine spiritual vein from the ground with the spirit of the Ghost Realm Void Spiritual Vein, he returned to join everyone.

It was also completely dark.

In the space of the demon cave, a blood-colored full moon actually appeared.

It wasn't really a moon, just a projection of a blood moon somewhere in the world.

As time passed, the fog on the high mountain in the center of the island finally dissipated, and at one point, a large vertical eye phantom appeared on the top of the mountain.

The huge vertical eyes are releasing boundless demonic energy all the time.

Around the pitch-black pupils, infinite demonic fire burned.

It's really like the eyes of the Demon King, staring at your soul through the infinite universe.

Everyone was shocked on the spot, and Li Suian was no exception.

Looking at it, it seemed that layers of whispering echoed in my mind, and my spirit fell into confusion, and a trance expression appeared on my face.

"Don't even look at those eyes."

Li Sui'an suddenly shouted.

Taiyi Wuyan burst out, enclosing everyone in it.

The sword qi of the Taishang Qi Dragon Branch roared, and the sonorous sword roared and the sound was endless, exploding in everyone's ears, and directly waking everyone up.

"Ahh

At this time, Ying Susu suddenly screamed.

With a frightened expression on his face, bloodshot from the corners of his eyes.

Li Sui'an was startled and slapped her on the back of the head, knocking her unconscious.

"What's wrong with her?" Zhong Shan asked.

Li Sui'an said solemnly: "Her eyes saw some terrifying existences that should not be seen. ”

"Let me treat her."

A little girl took the initiative to take over Ying Susu, her hands exuding a green glow, and she was treating Ying Susu's head.

"Lao Chen, how can this be?" Hutu asked, confused.

Chen Xuan looked dazed, and he stammered a little when he spoke, "Last time...... The last time I came to explore, it wasn't like that. It felt like the one-eyed had gotten a little bigger, and it was terrifying. How so? ”

Zhong Shan is one of the few who can stay awake, and his face is not good-looking.

Li Sui'an looked at him with a serious face and said, "I suggest that you clean up a batch of monsters on the outskirts of the island, don't explore this demon cave too deeply for the time being." ”

"Even you ......," Zhong Shan looked surprised.

Li Sui'an was very helpless, and had to nod and admit, "I have found the spatial anchor point, and the anchor point is the magic eye phantom." But it's too dangerous, it's not an ordinary monster, it's more like the eyes of a certain demon king, watching through the layers of demon abyss. We...... Let's find another way. ”

Zhong Shan knows Li Sui'an's ability, and even if he says so, there is really no way.

Take advantage of the prosperity and return with defeat.

At least his life was saved.

The crowd was forced to retreat to the outskirts of the island.

The sea around the island gradually rippled, and under the illumination of the blood-colored moonlight, the waves surged one after another, getting bigger and bigger, and becoming more and more dense, and the entire sea area showed an undulating scale layer.

A large number of fish-men and monsters flocked to the island in droves.

"When will it detonate?"

"Wait."

Until a huge monster washed ashore, an explosion rang out.

This is the crystallization of human science and technology, even if it has been regressed for more than 100 years, it is still infinitely powerful.

The Bombing Monsters were torn apart, and blood was scattered all over the sea.

But that's about it.

The change of the underlying rules, if humans can't break the rules of aura, they will no longer be able to create a big killer against the invasion of another world.

Meanwhile.

Outside the Demon Cave, the sea of Kunshi set off strong winds and waves, and the sea water spread wildly through the mangrove park.

One by one, the behemoths were all summoned and took the initiative to burrow into the space of the demon cave.

……

The crowd poured out all the anger that had just been deflated at the Demon Eye on this group of monsters.

"Kill!"

Li Sui'an fired three swords in unison and led the group of ghosts to rush up.

Even in the most elite team of awakened people in the two cities, Li Sui'an's strength is obviously higher, and in terms of monster killing efficiency, he is far ahead.

Thirty-six ghost servants, rushing all the way to kill.

It's almost all sideways.

As long as it's not a monster that exceeds the fourth order, they will rush up and kill Kaka indiscriminately.

Basically, it didn't last more than five seconds.

Even in the fourth order, there are Nezha who greet Xiao Zhen and the God of Wealth.

Li Sui'an just chose those huge sea monsters.

The rules of the demon cave, every time you slaughter a monster, you will get the feedback of the demonic energy, and it also comes with a demonic intent.

The demonic qi is also helpful to the ghost servants, making their own yin qi more condensed and powerful.

The low-level ghost servants are all helping the big brothers to quickly increase their level.

Basically, after a big battle, it can be raised to the level of the sixth level of the ghost pawn.

Of course, this is also due to the fact that the ghost servants under Li Sui'an are all spirit ghosts with high soul bone grades, and their qualifications are extraordinary, and their cultivation speed cannot be slow.

With the extreme use of the "Ghost Suppression Technique" for a long time, Li Sui'an's total amount of divine souls also began to increase slightly, and the strength of his divine thoughts increased slightly.

The continuous use of "ghost control techniques" is the same as refining the gods to "visualize" and practicing qi to "regulate breathing", and it also invisibly has the effect of hammering and forging the soul.

And the effect is not weak.

After all, he still has ten personal soldiers to feed back.

As the level of the ghost servants under his command increases, Li Sui'an's divine soul power will also increase.

The cultivation of the divine soul is linked to the cultivation of the ghost servant, and the faster the ghost servant improves, the stronger his own divine soul will be.

Not only cultivated himself, but also strengthened his subordinates, it was really a double win.

Thinking about it, these ten pro-soldiers cost him more than 100,000 merits.

Especially Nezha.

But he ate 100,000 merits alive.

"Is my 100,000 merit so delicious, can't you work for me now and come back?"

After inspecting it with satisfaction, the ghost servants were all eating with lush soul fire, which was much stronger than those listless wild ghost pawns. Of course, there is still a big gap in quantity, and it is still much worse than Li's requirements.

Now he is also the king and hegemon at the third-order level.

But the strength of the Demon Cave is getting stronger and stronger, and there will be one hundred and eighty heads in the future before they can gain a foothold in the Demon Cave.

If he is cleaned up by dividing five by two as soon as he shows up, where will his old face go!

Lord Hutu's abilities are biased toward support and field control, but they're also extremely effective.

"A fifth-order monster has appeared!"

A huge demonized sea serpent went on a rampage, killing everyone.

"Curse of Slowness!"

A red light emanated from Hutu's hand and pointed at the sea serpent.

A red glow erupted in the night sky, as if something terrible had happened.

An illusory crimson chain appeared on the body of the giant sea serpent that was rampaging, and in an instant, the speed slowed down.

It's not even as good as a third-order sea serpent.

"Armor-Piercing Curse!"

Hutu kept moving, and once again released a green light that fell on the sea snake, and the powerful scales on the sea snake seemed to bubble, and the whole body was covered with an illusory green net.

After doing these two attacks, Hu Tu's face was also a little pale, and his eyes instantly looked at Li Sui'an.

No matter how powerful Li Sui'an's timing was to grasp the battle situation, it goes without saying that the Taishang Qi Dragon Branch turned into a hundred zhang Taiyin Youjiao Sword Dragon, and cut it down in an instant, instantly dividing the demon snake into three hundred and sixty-five pieces.

"Wow!"

This powerful result made even the initiator Li Sui'an stunned.

After all, this was a fifth-order sea beast that was eighty meters long.

"Hahaha, Xiao Li's sword is still so powerful."

Hutu burst out laughing.

Li Sui'an also smiled, "Although my sword can kill the sea snake, I can't do it so neatly." If the city lord Hu is free in the future, he can join hands with Li to hunt powerful beasts. ”

"Haha, no. This is already my means of pressing the bottom of the box, and the mental consumption is too great. ”

"It's easy."

Li Sui'an threw out a bottle of Guiyuan Dan and threw it to him, "Eat one pill to assist in recovery." ”

Hutu took it, sniffed it, and swallowed one on the spot.

Immediately, I felt that my mind was clear, and the feeling of excessive mental consumption was instantly relieved.

I can't help but light up.

"Good medicine!"

This battle lasted for most of the night.

There are countless monsters to slay.

In the end, everyone else retreated and rested, leaving only Li Sui'an and Zhong Shan still fighting, and a group of ghost servants still attacking and killing.

"He's still so energetic, what level of ability is it?"

Su He was also convinced.

He is close to running out of oil and the lamp is dry, and Li Sui'an is still as active as ever.

Leng Tiedao: "I don't know how many steps, but I know that in a battle like this, he can fight for another seven days and seven nights." ”

"Huh? Have you seen it? ”

Leng Tie remembered Li Sui'an's feat of fighting for seven days and seven nights, and he had to accept it.

After briefly talking about the battle of the steel base city to defend the zombie siege, everyone else was confused.

"Seven days and seven nights, what a person."

Ying Susu also came to his senses, and retreated in the rear and did not participate in the battle.

By dawn, the entire beach was already stained with blue and red blood.

The MONOCULUS began to fade, and the monsters finally came to their senses and returned to the sea in droves.

Li Sui'an felt that his eyebrows were a little bulging, as if something was brewing.

But he always suppressed.

He understood the location of the mysterious cave and what it represented.

The essence of a monk's cultivation of the divine soul is to cultivate the secret treasure of the divine palace.

That is, the so-called "Heavenly Eye", "Yellow Garden" and "Inner Scene" in Taoism, which modern medicine calls "pineal gland". Ancient scholars such as Plato and Descartes in the West also wrote about the yearning for the pineal gland and called it a treasure house of the soul.

Medical research on the Blue Star has shown that after the age of eight, the pineal gland will continue to calcify, eventually becoming a substance similar to tooth enamel, completely losing its effectiveness.

The difficulty of opening the Shrine Vault the day after tomorrow can be imagined.

Now Li Sui'an's divine soul strength has reached the level of the twelfth layer of Great Perfection of Qi training.

Let's take a look at the big-headed soldiers under his command:

Even Nezha has been upgraded by one level, reaching the realm of a twelfth-level ghost pawn.

Xiao Zhen and the God of Wealth have also reached the realm of tenth-level ghosts.

Ah Fei, Zilong, Hu Hou, Evil Lai, Meng Qi, Han Sheng, and Impermanence have all been promoted to the ninth level of ghost pawns.

Even if only 10% of the Divine Soul is fed, it is enough to push Li Sui'an's Divine Soul strength to the twelfth layer of the Great Perfection.

But the twelfth layer is not the limit of Qi cultivation, and now is not the time to sublimate the divine thoughts.

After completing this battle.

The road of the Demon Cave Raider had to be temporarily terminated.

The way back was unusually smooth, and Guy Li Sui'an directly opened any door.

The two cities did something agreed, but Li Sui'an was indifferent.

After harvesting a batch of Evolutionary Crystal Nuclei, he returned to Steel Base City. Li Sui'an had time to ask Ying Susu, what did he see at the beginning?

Clinker Ying Susu didn't mention it this time, just shook his head, as if he had a hard time.

Li Sui'an's face instantly became solemn.

After a little arrangement, the cross-border teleportation journey began again.

Return to the Xiuzhen Realm.

Xuanyin Sect.

Li Sui'an tidied up a little, and appeared outside Xuanyin Mountain in a worried mood.

"Master Xuanyin is here, and the disciple Li Sui'an asks to see Master Xuanyin."
