When the little old man heard this, he led Yu Ke to a shelf, but saw that dozens of transparent glass bottles were densely placed on the shelf, and there was a ghost in each glass bottle. "All the low-grade spirit ghosts in the small shop are here, these spirit ghosts were hunted by the monks of Xuansha Valley when they went out to practice, and they were sold to the small shop if they couldn't use them. ”

Yu Ke listened to the little old man's chatter while checking the ghost in the bottle.

I don't know what material this bottle is made of, but from the outside, the golden veins on the ghost's body are clearly visible, from one vein to three veins. The lowest price is 10 spirit stones, and the highest price is 100 spirit stones.

"Senior brother, this spirit ghost is only two yin veins, why is the price so high, fifty spirit stones, and it is almost catching up with the spirit ghost of three veins. Yu Ke asked puzzled, pointing to a bottle.

"Hehe, you don't understand this, right?" The little old man smiled slightly, took off the bottle and held it in his palm, and the mana was slightly urging, but he saw that the two golden veins on the spirit ghost in the bottle became clearer and clearer, and there were dots of golden stars next to the two veins, faintly connecting them to form a yin vein.

"This is a second yin vein spirit ghost whose qualifications are extremely close to the three yin veins. The little old man smiled proudly: "Do you think that the qualifications of the same two spirit veins are the same? ”

"Oh, I see. Yu Ke nodded slightly, and then said, "Can this spirit ghost be cheaper?"

"No, I can't. The little old man's face was pale, "Senior brother doesn't know yet, this shop is an industry under the name of the ancestor, and it never bargains." ”

"Okay, I'll just want this ghost. Yu Ke nodded slightly, "In addition, does your store have any pills suitable for the second and third layers of Qi cultivation period?" ”

"Yes, of course. The little old man said: "With the current realm of the junior brother, it will be done with Yang Yuan Dan." This Yang Yuan Pill is much stronger than the small Yang Yuan Pill that you gave out when you started, and it is enough for you to use the fourth layer of the Qi cultivation period. ”

Yu Ke: "What's the price?"

Little old man: "Three spirit stones for one." ”

"I want one hundred and fifty. ”

"Haha, together with the spirits and ghosts, a hundred spirits. The little old man was a little stunned and took out three dark green jade bottles and handed them to Yu Ke along with the bottles containing spirit ghosts, "It seems that the junior brother is still quite valuable." ”

"What is the net worth, if you have a worth, I will buy a medium-grade spirit ghost. Yu Ke shook his head slightly, handed over all the remaining hundred spirit stones to the other party, waved his hand to put away the things, said goodbye to the old man, and returned to the cultivation residence.

Using all the remaining hundred spirit stones in one go, Yu Ke was also very distressed. However, the path of cultivation should be brave and diligent, and it is the right way to exchange the spirit stone for cultivation and strength.

In the cultivation room, Yu Ke carefully transferred the spirit ghost contained in the bottle to the soul ring, and then with a thought, one of the bad ghosts previously enslaved directly disappeared, freeing up a place for the new spirit ghost. Then according to the ghost control technique, the spirit ghost recognized the master.

After recognizing the master, the spirits and ghosts are no different from other ghosts, except that there is a subtle sense between them and the master, and they can understand the master's intentions.

If you want to successfully develop the potential of the ghost servant, let it embark on the path of cultivation. As the master, you also need to spend your own essence blood to perform a blood sacrifice on it.

After the blood sacrifice, the ghost servant can absorb the energy of the underworld to cultivate himself, and he can also comprehend some special abilities and spells.

After the spirit ghost successfully recognized the master, Yu Ke had completely controlled its life and death, and just one thought could make it disappear. And once the master is successfully recognized, the master-servant relationship cannot be dissolved, and when you want to change other spirits, you must kill this spirit ghost to free up a valuable "place", the most important thing is that the master dies and the servant dies, and this spirit ghost is absolutely loyal to the master. Only in this way can you dare to seek help from ghost servants with confidence and boldness when you encounter a bottleneck, without worrying about backlash.

Of course, the cultivation of the corresponding master will also limit the development to a certain extent, for example, Yu Ke is only one level in the Qi cultivation period now, so his ghost servant can only be promoted to about the fourth level of the Qi training period at most. Of course, with Yu Ke's qualifications of the five spirit veins, it would be very difficult for this ghost servant of the two yin veins to surpass him, unless there were a lot of resources to smash it down.

As soon as the spirit ghost servant flew out of the soul ring, he immediately turned into a cloud of yin wind and revolved around Yu Ke, and the ghost screamed twice from time to time.

"Come here" Yu Ke's heart moved, and the ghost servant immediately flew to the front obediently.

Vacating the ground, the grimace doppelganger flew out of the body's right arm.

The blood sacrifice requires a large amount of essence blood and will also consume some cultivation, and the mana of the ontology cultivation is not easy to come by, but the true essence blood of the ghost face clone is outstanding, and the true essence blood that makes up for the loss is naturally much faster than the main body. Yu Ke naturally wouldn't let the clone goppelganger go.

The grimace clone slashed his fingertips, oozing out a little essence blood, and then using the essence blood as a guide, a blood-colored rune was drawn in the air and pressed on the ghost's body.

The blood mark reached the body, and the body of the spirit ghost and ghost servant began to tremble slightly, and a mouth allowed the fingers of the doppelganger who were still bleeding.

The grimace clone turned his heart sideways, and the flow of mana forced out more essence blood, allowing the hungry ghost to suck it to his heart's content.

After a while, the ghost servant let go of his fingers, and the clone's originally rosy cheeks turned pale, but it was a sign of excessive blood loss and mana depletion.

After the blood sacrifice, the ghosts and ghosts fell into silence, and the whole child curled up in a ball, no longer active as before.

Yu Ke knew that the ghost servant needed a little time to digest the results of the blood sacrifice, so he swept the soul ring in his hand and put it away.

After putting away the ghost servant, or out of curiosity, Yu Ke's ghost sent the god to activate the identification function of the soul ring...

"Huh, how can this be?" The state of the ghost servant shocked Yu Ke's heart, but he saw that under the light, the two golden veins of the ghost servant were shining, and the other dotted veins were becoming more and more clear under the light of the ring, and a little bit of gold continued to condense into that yin vein.

The sudden change surprised Yu Ke inexplicably.

Half an hour later, the golden star finally stopped appearing, and the golden veins that had not yet taken shape were completely condensed.

A blood sacrifice made the spirit ghost who originally had only two yin veins become a three-yin vein spirit ghost.

"Could it be the effect of the doppelganger's blood?" Yu Ke suppressed the surprise in his heart and secretly speculated. If the blood of the clone makes sense, this grimace clone is very special, and it seems understandable what changes have happened to its body.

"Try again, maybe it was just an accident. ”

Yu Ke's heart moved, and he summoned a bad ghost that had been enslaved before, and let the clone continue the blood sacrifice.

As the essence blood flowed into the body of the bad ghost servant little by little, the face of the grimace clone became more and more pale,

A feeling of dizziness came, and just when the grimace clone was about to lose its support, the bad ghost ghost servant finally stopped sucking and still curled up in a ball and went into a dormant state.

Seeing this, Yu Ke couldn't wait to include it in the soul ring and open the identification function of the soul ring to observe.

Sure enough, the result did not disappoint Yu Ke, under the light of the ring, the golden starlight in the transparent body of the bad ghost and ghost servant quickly gathered, and soon condensed a faintly visible golden vein, and then the golden vein became more and more shiny, and after a vein was fully formed, the golden star still had the strength to condense about a third of the yin veins, and finally stopped.

This blood sacrifice not only helped the inferior ghost ghost servant develop the first yin vein, but also developed about one-third of the second yin vein.

During the whole process, Yu Ke's heart was beating violently, and the endless excitement was mixed with a hint of panic.

The blood sacrifice to improve the qualifications of the ghost servant is simply a fantasy, it is simply impossible, but Yu Ke encountered it.

If the previous talent of being able to enslave the five natal ghost servants was a heaven-sent treasure for Yu Ke, then the blood of the clone was the key to unlocking that treasure.

Calm, must be calm.

He can enslave five natal ghost servants, although his qualifications are against the sky, and others envy him, but he can't take it away. But the blood of the doppelganger can improve the qualification of the ghost servant This thing can never be exposed, and now the strength is not good, once people know about it, I am afraid that they will force themselves, and even coerce and control, and eventually it is inevitable to become the meat head of others, just like raising pigs and eating meat, squeezing the essence and blood of their own clones.

This matter must not be known to anyone, Yu Ke instantly made up his mind.

Since God has allowed himself to travel to this bizarre world of immortals and demons, and has also given himself the qualification to cultivate immortals and cultivate the Dao, and given himself a very clever doppelganger, he naturally has to seize the opportunity and do something earth-shattering, otherwise he will not only be sorry for himself, but also live up to God's wishes.

For a while, Yu Ke was full of pride in his heart, and the whole person invisibly had a trace of pride.
