Ziyun City is vast, and the southwest city area that Lu Kun walked through is dominated by Immortal Cultivator Fang City, and the northern city district is where the auction house is located.

The auction house here is a bit interesting, there is no auction, if the immortal cultivator has items to sell, he directly entrusts the auction, and after the appraiser evaluates, he will negotiate a fixed price and a bidding price with the seller, and hang it on the auction house list for half a year.

When the time expires, it either ends at the auction price or is bought at a fixed price, and if no one cares, the seller needs to pay a storage fee to take it away.

Lu Kun briefly checked the list of auctions, with his current vision, there was nothing that caught his eye, as for the things related to the imitation of the spirit treasure refining method, there was nothing, so he left here and went to Dongcheng District.

This area is densely covered with rows of cave mansions, not so much cave mansions, but rather large mansions shrouded in prohibitions, these prohibitions are connected together, and they are also connected to the forbidden array of Purple Cloud City.

Attacking any cave is equivalent to competing with the formation of the entire city, and the security is extremely high.

Lu Kun chose a small courtyard on the outermost periphery, he opened the prohibition through the token and walked in, the inside was very simple, except for a courtyard with a medicine field, there was a cultivation room, and on the ground in the room, a piece of jade pu and a magic gathering array were simply placed.

He didn't care about the slightly thin demonic qi here, with his revealed foundation building period cultivation, such a cave mansion was in line with his identity.

Lu Kun entered the room, blocked and forbidden, a flash of spiritual light, Shi Yin'er's delicate body appeared, she looked a little self-reproachful and said: "Pavilion master, Yin'er's strength is too weak to help, if Xiao Jin is here, the pavilion master should be able to find out about the big bird in advance." ”

Although Shi Yin'er had been in Lu Kun's ribs, she could sense the situations that were happening one after another outside, but unfortunately she was not strong enough to participate in the battle.

Lu Kun shook his head and said, "Xiao Jin is refining his own bloodline, preparing for a breakthrough in the bone transformation period, and it is still a realm of bone treasures, and there is no way for the spiritual ear to monitor a hundred miles away." ”

He paused and said with a smile: "It's also a shame to bring you out, otherwise I won't be able to urge the Immortal Artifact, let alone find the best way to eliminate the will of the Xenomorph." ”

"Gu Deming used the innate supernatural power of the dementor bird to inject the endless meaning into my body, it was hidden in the depths of the five internal organs, we fused the essence and blood, and used the method last time to eliminate the will of the alien species. ”

Shi Yin'er nodded, her dark gray lips opened slightly, and a crystal clear eight-sided crystal slowly floated out.

Looking at this crystal that exuded a strange aura, Lu Kun's expression was quite emotional.

After exchanging secrets with the corpse kings of the Middle Immortal Mountain, he realized that this thing called a holy object by the Immortal Insect Clan was actually condensed with the essence of divine consciousness, and those corpse kings called it the Soul Crystal.

According to the information left by the senior of the golden armor corpse, the crystals of the spirits left behind by these Immortal Worms were at least condensed by the Immortal Worms above the late stage of the Transformation Spirit.

The divine consciousness inside is very pure, without any divine soul breath, which is completely different from the divine consciousness breath of an immortal cultivator, Lu Kun feels that it is more accurate to describe it with pure spiritual power.

The golden armor corpse coincidentally discovered the activation method of the spirit crystal, and it could use the essence spiritual power inside, it borrowed this energy, digested the will of the Yuan Shen in the Yuan Infant of the Transformation God, and condensed a Divine Consciousness Crystal in the brain.

With its help, the corpse pill refined the true element in the Yuan Infant, and combined it with the power of Yin and Cold to generate the same level of energy, the Immortal Yuan.

It can be seen from the advancement path of the golden armor corpse that the Hades Insect Clan has not comprehended the power of will, and the key point for the breakthrough of the Worm King level is to condense this high-level divine consciousness crystal.

The combined supernatural power of the five corpse kings of the Middle Underworld Mountain is the secret method created by the golden armor corpse according to its own breakthrough process.

By activating the spiritual power in the spirit crystal, to fight against the power of will, the five tenth-level peak corpse pills, with the help of pure spiritual power, refine the vitality in the best spirit stones, and transform the temporary spirit element.

This divine power can not only fight against the will of the gods, but also against the true element, even in the outside world, it can also greatly improve the control of the heaven and earth vitality and the demon vitality, the only shortcoming, its power is only close to the transformation of the vitality, can not really reach the attack power of the transformation period.

This secret technique has great reference value for Shi Yin'er's future breakthroughs, and for Lu Kun, the use of the spirit crystal is the biggest gain.

The pure spiritual power it activates can fight and dissipate the power of will, and the method of healing he once used to consume the will with the help of a little spiritual power breath in Shi Yin'er's blood, if he can directly activate the spirit crystal, the efficiency will definitely increase greatly.

One of the conditions for activating the method is that it requires an incomparably rich essence blood.

The tenth-level silver armor corpse is activated by the essence blood in its body, and the rich essence blood assists in a blood sealing method, drawing out the breath of the Immortal Insect in the blood, which can activate the spiritual power in the Soul Crystal.

The five corpse kings fought to the end, the cold power of the corpse pill was sufficient, and there was more than one top-grade spirit stone in their hands, and the underworld yuan could support it for a long time, but the essence and blood in their bodies were limited, and they couldn't keep urging the underworld crystallization.

Therefore, after these corpse kings saw Shi Yin'er, they were shocked.

They knew that corpse qi could be controlled by refined blood pressure, and like Shi Yin'er, who couldn't sense corpse qi at all, the essence and blood in his body was already equivalent to the level of three or four tenth-level silver-armored corpses.

The silver armor corpse has abundant essence and blood, not only is the physical body close to the human race, the meridian dantian is perfect, the cultivation speed has increased greatly, and the combined secret technique can also support it for a longer time.

This is the reason why they are so hungry for Lu Kun's essence and blood.

......

"Let's get started, let's activate the Wraith Crystal. ”

Under the action of the power of the void, the spirit crystals were suspended between the two, and the mouths of Lu Kun and Shi Yin'er opened at the same time, and two balls of silver essence blood spit out, fusing with each other in mid-air.

The blood circulated and intertwined, and a special aura fluctuation gradually emerged, which was very similar to the power of yin and cold, but it was a little different, full of a feeling of dead silence.

This is the unique aura of the Hades Worm Clan, or the Hades Attribute.

To activate the holy relics of the Hades Insect Clan, no matter how thick Lu Kun's essence blood is, it is useless, and the blood must contain this deathly silent aura of the Netherworld.

Shi Yin'er's blood was just a guide, in order to activate the underworld attribute in the depths of Lu Kun's essence blood.

As this dead breath appeared, the blood fell on the crystal of the underworld, melting into it as if the blood was dissolved in water, and then a spiritual light with a multicolored luster, like a rainbow, shot towards Lu Kun.

In front of the latter, a silver blood mist appeared at some point, and after these mist were hit by the rainbow aura, they turned into tiny ice crystals, which looked like silver snowflakes, flashing with colorful halos.

Lu Kun looked at this silver snowflake and felt a little embarrassed.

"At the time of the breakthrough that year, the bone treasure was too powerful because it fused the silver dragon meteorite, and the qi and blood magic power could not refine it, so it devoured the qi and blood underworld demon pill, so that the qi and blood magic power mixed with the underworld attributes, and accelerated the refining of the bone treasure. ”

"If you don't have this underworld attribute, I'm afraid that you can only activate the spirit crystallization when Shi Yin'er enters the realm of the tenth-level silver armor corpse. ”

These thoughts flashed through his mind, and Lu Kun took a deep breath, and this cloud of ice crystal blood mist that exuded a unique aura poured into his mouth one after another.
