It took a day of hard work for Chu Xiao to get all the elixirs and implant them all into the basin that had been prepared a long time ago.

Since there were too many types of elixirs, and the cultivation soil could not be configured one by one, he used the top-grade cultivation soil purchased from the market, which was quite expensive.

Chu Xiao carefully counted the elixirs obtained from the Wuliang Cave Mansion, all of them were high-grade elixirs above the prefecture-level upper grade, ninety-eight kinds of top-grade elixirs at the prefecture-level level, a total of three thousand one hundred and eighty plants, seventy-seven kinds of top-grade elixirs at the prefecture level, a total of three hundred and fourteen straines, fourteen strains of heaven-level lower-grade elixirs, and five strains of heaven-level middle-grade elixirs.

So many high-grade elixirs, all of them are extremely rare elixirs, and they are all innate elixirs that have not undergone technological transformation, the ingredients of the medicine are extremely precious, and the most commendable thing is that the age of these elixirs is extremely high, at least more than 10,000 years, according to the market price, I am afraid that the total value is more than 100 billion.

Of course, all the elixirs added up were not as valuable as that heaven-level top-grade Soul Eater Ghost Mushroom, and even gave birth to a mature demon spirit.

In order for the elixir to give birth to a demon spirit, it must reach the heavenly level, and the year must be more than 10,000 years, and this is only a possible surname, in fact, 10,000 heaven-level elixirs that meet the conditions, not necessarily one can give birth to a demon spirit, which shows how precious the elixir with a demon spirit is.

It is said that refining the elixir with the elixir of the demon spirit can raise the level of the elixir by one level, and it can refine the elixir that is 100% perfect.

Undoubtedly, the more than a dozen heaven-level elixirs that Chu Xiao obtained from the Boundless Cave Mansion all had the possible surnames of breeding demon spirits.

However, it is not easy to breed a demon spirit, in addition to meeting the above conditions, there must also be a specific environment, a specific opportunity, etc., just like a monk to reach a high level, it is not enough to practice hard, there must be enough luck and opportunities, after all, once the elixir gives birth to a demon spirit, it is equivalent to opening the spiritual wisdom, which is simply a huge leap.

Suddenly, when Chu Xiao was inspecting those heaven-level elixirs, he discovered an unexpected situation from the cultivation system.

"This is too perverted, isn't it, it can actually make the heaven-level elixir that meets the conditions have a chance of giving birth to a demon spirit with a chance of more than ten percent? In other words, out of ten heaven-level elixirs that meet the conditions, one may be able to give birth to a demon spirit?"

Chu Xiao showed a hint of shock on his face and muttered.

Generally speaking, the heaven-level elixir gives birth to demon spirits, which must be conceived naturally, and cannot be transferred by human will at all.

The legendary immortal has great magical powers, can ignite grass, trees, earth and stones, develop spiritual consciousness, and turn into spirits and demons.

However, this is just a legend, whether it is true or not, it cannot be confirmed, but in the future cultivation civilization, a strange spirit planting technology has been researched, which can make the heaven-level elixir that meets the conditions increase the probability of giving birth to demon spirits.

It's a miraculous technique, as if a new life has been artificially created.

Chu Xiao's heart moved, he had more than a dozen heaven-level elixirs, the lowest one was more than 15,000 years old, and the highest was more than 21,000 years, this was the best experiment, maybe he could cultivate a few demon spirits.

According to the description in the cultivation system, if you want to artificially cultivate demon spirits, you need a special kind of vitality - Qiling Yuanqi, a kind of vitality that can open the elixir and spiritual wisdom.

This kind of vitality belongs to the heaven-level vitality, and it is a series, from the heaven-level lower grade to the heaven-level masterpiece, the more advanced the spiritual vitality is for the elixir to breed demon spirits.

However, with Chu Xiao's current professional level, he must reach the ninth grade specialist level before it is possible to deploy the heaven-level lower-grade Enlightenment Vitality, so this experiment can only be stranded for the time being.

He couldn't help but sigh that his professional level was too low, and he was also constrained in doing things.

Looks like it's time to step up the class level.

In addition, Chu Xiao restarted the cultivation of the third stage of the baby mushroom, which had been stopped for a period of time, and the required vitality had already been deployed, and when transforming the Spirit Plantation Garden, Chu Xiao deliberately made a small room of more than ten square meters in the central closed building, which was specially used for cultivating baby mushrooms, and could adjust the concentration of strange vitality released by the Soul Eater Ghost Mushroom, which had a great effect on the cultivation of baby mushrooms.

After coming out of the Spirit Plantation Garden, Chu Xiao saw that it was still early, and immediately entered the cultivation retreat room.

He sat down, and then solemnly took out a black box more than a foot long from the time table, which was full of strange textures, and looked full of antiquity.

Looking at the box, a trace of heat flashed in his eyes, and then he exhaled lightly, stretched out his hand and made a trick, and entered it, and suddenly the black box opened, revealing a handful of feet long, and the whole body was full of blue light, like a clear spring, it didn't look a little dazzling, warm and soft.

This is a flying sword, a flying sword obtained from the Infinite Cave Mansion.

Superior Spiritual Weapon!

The flying sword is a foot long and a finger wide, and has no hilt, only a blade.

On the blade of the sword, there is a strange texture, like a charm, flickering with the blue light, and there are two extremely simple words - immeasurable.

This is an immeasurable flying sword!

Chu Xiao looked at the immeasurable flying sword in the box, his eyes were full of surprise, this is an attack-type magic weapon, a high-grade spirit sword, worth more than a billion spirit coins, and if there is no channel, it cannot be purchased at all.

The most important thing is that this is an ancient flying sword from ancient times, and its value is even higher.

With this flying sword, Chu Xiao's combat power will rise in a straight line.

Originally, at his age, he would never be able to have an offensive magic weapon, but as long as he didn't say it, who would know, not to mention that with his current identity, with a magic weapon, even if he was discovered, it was estimated that there would be no big problem, if it was a civilian without an identity, the surname would not be the same, this is equivalent to China in the previous life, illegally owning firearms.

Next, he will sacrifice this immeasurable flying sword.

Sacrificing and refining magic weapons is not an easy thing, especially if it is a magic weapon at the level of a high-grade spiritual weapon, it is even more difficult, with Chu Xiao's cultivation of the true level, it is extremely difficult, even if it can be preliminarily refined, it is difficult to operate as expected, especially the more advanced the magic weapon, the higher the mana that needs to be consumed.

Chu Xiao's face became solemn, and then he reached out to the flying sword and pressed his fingers to the blade.

It is worthy of a flying sword, extremely sharp, just by virtue of the flying sword body, it is enough to cut gold and break iron, Chu Xiao's fingers just touched the flying sword, and immediately felt a piercing chill penetrate in, along the arm into the whole body, at the same time, he could keenly sense that his fingers had been cut by the flying sword, and streams of blood gushed out, and were devoured by this flying sword madly.

This is the first step in refining the magic weapon, the blood sacrifice!

However, this blood sacrifice is not just a drop or two of blood, it must allow the flying sword to absorb enough blood, so that it can establish a preliminary connection with the flying sword.

Reiki has a spirit surname, and once it absorbs enough blood, then it will have a blood-related communication with the cultivator before it can proceed to the next step of sacrifice.

"It's worthy of a top-grade aura, and the blood needed is really a lot!"

A smile tugged at the corner of Chu Xiao's mouth, and he could feel that the flying sword was still devouring his blood.

After losing a full tenth of the blood, the Infinite Flying Sword stopped absorbing, and the original cyan luster was dyed with a layer of blood light, and these blood lights were composed of countless blood-colored runes, at this moment, Chu Xiao felt that he had an indescribable connection with this flying sword, as if it had turned into a part of his body.

However, he wanted to control this flying sword, but it was still impossible, as if it was a part of his body, but he couldn't move, that feeling was really uncomfortable, like a person who had suffered a stroke and completely lost control of a part of his body.

Most importantly, this feeling will continue until the Dharma Weapon Sacrifice is perfected.

Call!

Chu Xiao exhaled lightly, and the next thing was the most critical mental sacrifice, if the dripping blood sacrifice was just to make the flying sword connect with him, then the mental sacrifice was to allow him to control the flying sword, just like a patient who had a stroke and recovered his out-of-control body.

Suddenly, he stretched out his hands, his ten fingers flew, and one after another spells condensed out and entered the flying sword, and suddenly the flying sword buzzed and vibrate.

This is Chu Xiao's special treasure refining technique, combing the flying sword, refining the various large arrays inside the flying sword, and finally achieving the purpose of complete control.

As the treasure refining technique entered the flying sword, the formation inside the flying sword gradually emerged in Chu Xiao's divine sense, but it was very vague at first, just an outline, and it was only a part, there were more and more treasure refining techniques, and finally the outline of the entire flying sword also appeared in his mind.

If you can construct the complete structure of the flying sword in your mind, then it can mean that the flying sword has been refined, and when the time comes, you can put the flying sword into the dantian and slowly cultivate it.

After half an hour of sacrifice, Chu Xiao felt tired, and then stopped the sacrifice, so far, the flying sword phantom in his mind is still very vague, and there is still a distance from the real success of the sacrifice.

However, Chu Xiao was not in a hurry, and then put away the flying sword, and then got up and walked out of the cultivation room, he felt a little weak all over his body, and his steps were vain, after all, when he was dripping blood just now, he lost too much blood, and he had already moved fundamentally, it seemed that he had to recuperate his body recently.

At this time, it was already dark, the lights were on at home, and the family had already returned.

The next day, Chu Xiao went to Ziyun Academy, after all, he hadn't gone to learn the formation from the Cheyuan Divine Craftsman for many days, and in addition, he had to allocate some vitality.

He first went to the purple cherry class, and just entered the villa, and just happened to meet Zhao Yingkong.

"You're finally here, you weren't hurt last time, were you?"

Zhao Yingkong's tone was as cold as ever.

However, Chu Xiao still heard a trace of concern from her tone, it seems that this thousand-year-old iceberg is not impersonal.

"Thank you Mr. Zhao for your concern. ”

Chu Xiao said with a smile.

"That's good, this is a Divine Armor Talisman, if you hold it, as long as it is not a cultivation that has surpassed the Law Phase, within half an hour, it will not be able to break through the defense of the Divine Armor Talisman. ”

Zhao Yingkong was like a trick, and there was an extra palm-sized jade talisman in her hand, which emitted a strange light, making people feel that she was extraordinary.

Chu Xiao checked it with the cultivation system, and couldn't help but be startled, it turned out to be a low-grade treasure talisman that could defend against the attacks of all supernatural spells.

"This, this is too precious, I can't ask for it. ”

He couldn't help but shake his head and said, it's very strange how could this thousand-year-old iceberg give him such a precious treasure talisman?

Even a martial arts warrior of the law phase level will probably salivate over this level of jade talisman, this is a life-saving talisman that can save people's lives!

"Take it, my grandfather gave it to you. ”

Zhao Yingkong's face was flat, but there was a taste in his tone that could not be refused.

"What, is the senior back?"

Chu Xiao's face was overjoyed.

"I came back and left. ”

Zhao Yingkong said lightly, and after handing over the Divine Armor Talisman to Chu Xiao, he left.

Chu Xiao looked at the Divine Armor Talisman in his hand, and his brows couldn't help frowning, could it be that the seniors came back just to give himself such a Divine Armor Talisman? Unlikely!

However, such a powerful divine armor talisman, don't do it in vain, it's still very useful.

Although he has a mature body contract demon spirit that can be compared to a strong person at the law level, it does not mean that he is absolutely safe, after all, in battle, sometimes the old ghost may not be able to protect himself, so this divine armor talisman can save his life.

Shaking his head, Chu Xiao put away the Divine Armor Talisman and immediately walked into the main classroom
