Half a month later, a black shadow in the depths of the "Black Blood Valley" was shuttling quickly in the black haze and fog that covered the sky and the sun, it was Liu Yu who was wearing the "Sky Eagle Ink Stained Robe", the landform in the depths of the "Black Blood Valley" was completely different from the surrounding poisonous forest, there were no trees, bare, continuous raised hills, forming a series of valleys of different sizes.

Liu Yu used the wind control technique to step on the raised strange stones, and quickly rushed forward, the soil with wisps of black smoke around him turned from time to time, stretching out a pair of black and festering bone hands, a rotting corpse hidden in the ground for cultivation, smelling the breath of a living person on Liu Yu's body, and was getting up from the soil.

By the time these clumsy rotting corpses crawled out of the soil, Liu Yu had already flown far away, dragging the rotten corpses and sniffing the residual breath in the air, limping out of dozens of steps, the residual breath in the air had already dissipated, and the rotting corpses dug a hole in the ground with their hands and feet, and buried themselves in the soil.

Liu Yu sometimes hangs some carrion beasts behind him, wolves, leopards, etc., the remains are relatively complete, and the running speed is not slow, but it can't catch up with Liu Yu, and after keeping up with the distance, it will naturally be thrown away by Liu Yu.

The fog was thick, the mountain wind was blowing, accompanied by bursts of ghost crying, and there were many ghosts hovering in the air, and a large number of ghosts wandered unconsciously with the wind.

Several yin spirits found Liu Yu running close to the ground, swooped down in the air, and threw themselves into the net and crashed into the golden oval magic cover raised by Liu Yu, bursting out clouds of black smoke, these "geist" level yin souls were too weak for Liu Yu.

Soon, Liu Yu came to the bottom of a large valley, surrounded by poisonous miasma and haze, and at the bottom was a huge crater like a volcanic crater.

At this time, the pit is spewing out bursts of black smoke rushing to the sky, forming a hurricane eye, and a large "yin vein" is connected to the bottom of the pothole, and the yin wind gushing out is extremely pure "initial yin erosion gas".

Liu Yu took the three-grade "Breaking Miasma Pill", came to the back of a sudden stone hundreds of meters away from the pit to avoid the strong wind, and at the same time cast the spell "Concealment Technique" to hide his own cultivation and breath, staring at the huge pit that gushes "Yin Qi" like a fountain.

According to ancient records, large "yin veins" often breed a special kind of yin soul "evil spirit", which is different from the acquired yin soul after the death of the living soul, the "living soul" is not dispersed, and the remnant soul is stimulated by the yin qi and transformed.

The soul body is composed of a large amount of pure "Initial Yin Erosion Qi" wrapped in a trace of "Initial Yin Evil Qi", which is spherical and invisible to the naked eye, born in the depths of the Yin vein, and rarely appears on the ground.

The pits at the bottom of these valleys in the depths of the "Black Blood Valley" are connected to the underground "Yin Veins", and the air flow gushing outwards is rumored to sometimes rush the "evil spirits" in the depths of the Yin Veins to the surface.

One of the few sources of the "Gang Sha Tai Chi Hua Yuan Technique" mentions the "First Yin Evil Qi" in the remarks, and it mentions this semi-innate Yin Soul "Evil Spirit".

If you can capture a large number of "evil spirits" and extract the trace of "Initial Yin Evil Qi" in their soul body, and accumulate a small amount, you will be able to make up enough of the "Initial Yin Evil Qi" used in the cultivation of the "Gangsha Taiji Transformation Yuan Technique".

Two hours passed, Liu Yu was still squatting behind the stone, mana poured into his eyes, casting the "psychic eye", staring at the tuyere of violently spewing black smoke, and nearly a hundred "shadow soul" level yin souls were circling at the mouth of the pit, greedily absorbing the pure "primordial yin erosion qi" gushing out from the ground.

Suddenly, the dozen or so soul bodies close to the mouth of the pit were condensed, and the shadow souls that were close to the "yin" level were all crazy and braved the violent wind, rushing towards the mouth of the wind.

Obviously, these shadow souls gathered at the mouth of the pit, in addition to absorbing the pure "Primal Yin Erosion Qi" cultivation that gushed out, there was also a glance, like Liu Yu, they were all squatting and guarding the "Evil Spirits" that were occasionally brought out of the ground by the violent Yin Wind, and the trace of "Initial Yin Evil Qi" in the soul of the "Evil Spirit" was undoubtedly a great supplement for the Shadow Souls.

"Bump", the soil splashed everywhere, the ground ten meters away from the mouth of the pit exploded, and a bloody shadow burst out, it was actually a "blood corpse" hidden in the ground to cultivate, which was very different from the corroded and festering "rotting corpse", this "blood corpse" had a complete body, the rough stiff skin that wrapped the whole body was blood-colored, very hideous, and the five fingers gave birth to long nails, sharp as claws.

I saw this "blood corpse" blast out like a cannonball, and the target was also the "evil spirit" that was blown out of the pit by the yin wind, first waved his hands in a row, sending out more than a dozen blood-colored claws, tearing apart the few yin spirits closest to the "evil spirit", and then let out a roar like a beast, deterring the yin spirits that swooped down in groups.

Nearly 100 Yin Spirits let out bursts of piercing and terrible wails, forced by the ferocity of the "Blood Corpse", hovering in mid-air and not daring to approach, and the "Blood Corpse" flew towards the "evil spirit" that was like a headless fly, trying to rush into the eye of the storm and return to the ground like a headless fly.

The yin wind at the mouth of the eye of the wind was too violent, and this "evil spirit" soul body was obviously too weak, and it was blown to shake, like a dead leaf in the rapid wind, and it couldn't get close to the "eye of the storm" at all.

When the hideous "Blood Corpse" rushed quickly, the "Evil Spirit" soul body flashed with a flash of inspiration, and cast the talent spell "Shadow Escape", turning into a cloud of black smoke and quickly fleeing outward.

"Evil spirit" is a kind of yin spirit, the yin soul has no body, and it has always been extremely fast, and "evil spirit" is one of the best, and the speed is even more amazing. However, the "blood corpse" was already equivalent to the foundation period of law cultivation, and the speed was not slow, and it followed and chased after it.

"Disease!" Liu Yu immediately summoned the "Jincun Sword", performed the "Imperial Sword Technique", and at the same time stimulated the "Xuanxue Escape", broke through the air, and also chased after him.

The second "Xuanxue Escape", the speed was extremely fast, and after a while, he caught up with the "Blood Corpse" in front, and the "Blood Corpse" saw that a cultivator was approaching, roared, turned around and rushed towards Liu Yu, his long nails glowing with blood, and he grabbed straight at Liu Yutian Linggai.

"Jin Yuan Thick Earth Shield", Liu Yu immediately drove the "Golden Meaning Earth Yuan True Qi" in the Purple Mansion, and condensed a golden dazzling light shield in front of him, the light shield not only contains the unique heaviness of the earth aura, but also injects the sharpness of the golden aura, and the defense is outstanding, and it easily blocks the claws of the "blood corpse".

Liu Yu did not entangle with the "blood corpse" more, and chased after the "blood corpse" to the fleeing "evil spirit", and the "blood corpse" that was blocked suddenly fell into a rage, and the bloody qi poured into his body, his eyes were red, and he smashed the light shield in front of him.

A few smashes, collisions only then smashed the "Golden Yuan Thick Earth Shield", followed by several huge hard stones on the ground, floating in the air, directly smashing towards the "blood corpse" in the air, this is Liu Yu's unique control of soil and stone after cultivating the "Golden Earth Society Tao Sutra".

The "blood corpse" poured into the bloody iron fist smashed the first few flying boulders, and was directly knocked away by the last boulder, and the "blood corpse" was covered in copper skin and iron bones, and it would not be injured by the boulder, but this delay had fallen a long distance, and Liu Yu was only a hundred steps away from the "evil spirit".

I saw Liu Yu's hands quickly closing the Heavenly Master's handprint, pointing at the front of the Dharma seal, and shouting violently: "Heavenly Master's edict, Yuan Qi is through the gods, chasing the soul and soul, fixed!"

As soon as the "Fixation Technique" came out, the "evil spirit" that fled in front of it stopped and was fixed in the air by an invisible force.

Although it has not been refined into the "Heavenly Master Mantra - Dao Soul Heart Sutra", this style of "Heavenly Master Mantra - Determination Technique" is mediocre, but it is still more than enough to deal with the soul body that has no physical protection and is only equivalent to the "Shadow Soul".

"Collect!" After succeeding, Liu Yu immediately summoned a green wood gourd carved with a gossip pattern, and sucked the "evil spirit" fixed in the air into the gourd, this green wood gourd was a special three-grade high-grade magic weapon that Liu Yu bought for a full 7,000 low-grade spirit stones, called "Bagua Soul Refining Gourd".

The "Bagua Soul Refining Gourd" is made of hundred-year-old spirit locust wood and soul suppression jade, which has the effect of imprisoning and refining the yin soul.

"Moo! Moo!" The blood corpse in the rear saw that the prey was robbed and roared angrily, so he got up and chased after him, but Liu Yu didn't intend to pay attention to this crazy blood corpse, and directly cast the "Xuanxue Escape Light" and evacuated into the distance.

Liu Yu is not afraid of this "blood corpse", this "blood corpse" has not retreated, and the armor has not been draped, it is obviously a blood corpse equivalent to the condensation period in the early stage of foundation building, if it is not in the "Yin Skeleton Ghost Land", it is not good for himself, Liu Yu really wants to take this "blood corpse" and try his current combat strength.

According to the physical appearance of the "blood corpse" in the foundation building period and the degree of condensation of the blood evil qi, the cultivation realm divides the "blood corpse" in the foundation building period into three stages, the condensation period, the blood armor stage, and the condensation pill stage, which correspond to the beginning, middle, and late stages of foundation building of the Fa cultivation, respectively.

In the "blood corpse" of the condensation period, the blood and evil qi first gathered, and there was still a rough and tough blood-colored stiff skin, and in the blood armor stage, the blood and evil qi was thickened, and it condensed into a tight air armor around the corpse.

When it comes to the Ning Dan period, the "blood corpse" is like the law cultivation, condensing a "blood pill" in the body, if you are lucky enough to survive the corpse destruction thunder tribulation, the "blood pill" is quenched into the "Great Dao Corpse Pill" in the heavenly thunder, and the overlord "corpse king" is achieved, and the cultivation is rooted in the golden pill period of law cultivation.

In addition to being in the "Yin Skeleton Ghost Land", I am afraid that I will fight with the blood corpse, attract other ghosts, and be surrounded by the crowd, even if I kill this blood corpse in the condensation period, it will not do much good.

In addition to a body of tough and stiff skin that can be made into leather armor, a body of carrion can be seen by evil cultivators, or it can be added as a spiritual material of some kind of poison, killing "blood corpses" and other copper skin and iron bones, extremely difficult ghost things, in the cultivation world has always been a thankless job, which makes most people unhappy.
