The formation of the primary storage space of the inscription formation is already familiar to Lu Yao, the carving knife is in hand, and it will be done in two hours, looking at the ring worn on the little finger of his right hand, Lu Yao's heart is excited.

Although Lan Wenwen is difficult to entangle, it is also very annoying, it was this ring that made everyone misunderstand the relationship between Lu Yao and Lan Wenwen, but I have to say that the ring that Lan Wenwen gave to Lu Yao is really a treasure, the moment the formation was successfully inscribed, there was a vision in the sky, and the Northern Big Dipper Lone Star was shining greatly, as if it was to cover the glory of the moon.

What's more, this time the space inside Lu Yao's space ring is large enough, if the copper ring destroyed by Lu Xuan before is compared to the size of a swimming pool, the current gold ring space is like an artificial lake, several times larger than before.

The inscription formation took Lu Yao a lot of energy, if it was changed to before, it would take at least three or four hours to recover to his heyday, but since the Jin Dan in his body changed, the recovery time was greatly shortened, and in less than an hour, Lu Yao felt that he was fierce and energetic.

With the space ring, now you need to refine some pills, these days Lu Yao's control of Qingyunding is also more skilled, and the refined pills are becoming more and more refined, but unfortunately, Lu Yao has mastered some simple alchemy methods so far, and most of the pills refined are to restore immortal qi or heal injuries and stop bleeding, and there is no pill that can really be called a panacea.

"Master, this time the treasure is in the world, it must be inevitable that there will be a fierce battle, can you teach me some more advanced alchemy methods in case of emergency?" Lu Yao hesitated for a long time, but still told his thoughts to leave Xinjiang.

If there is someone in this world besides Lu Yao himself who knows his strength well, then this person must be leaving Xinjiang, and he agreed to Lu Yao's request without saying a word.

"Martial arts are divided into ancient martial arts and immortal martial arts, and the elixir is naturally divided into grades, according to its medicinal power, it can be roughly divided into four types: elixir, elixir, immortal medicine and holy medicine. Lijiang said solemnly: "The elixir can be divided into two different qualities, the semi-elixir and the elixir, it is too early to refine the elixir with your current strength, let's start with the semi-elixir first." ”

"Master, what is a semi-elixir?" Lu Yao asked.

"The so-called elixir is an elixir with a certain concentration of aura, whether it is an unrefined herb or an artificially refined elixir, as long as its aura concentration reaches a certain level, it can be called an elixir." Lijiang explained: "But in the current world, the herbs that can reach the level of the elixir obviously no longer exist, so it can only be artificially refined to make the aura level of the elixir reach that realm, and the so-called semi-elixir is the elixir whose aura concentration is a little less than the elixir, and has not yet reached that standard." ”

"Master, can the semi-elixir be understood as an elixir with a concentration of spiritual energy that reaches half of the elixir?" Lu Yao asked for advice according to his own understanding.

"Wrong, the semi-elixir is not an elixir with a concentration of spiritual energy that reaches half of the elixir, although it is called a semi-elixir, but the concentration of the spiritual energy it contains can reach the quality of the elixir by only a millimeter, in other words, the so-called semi-elixir is an elixir that is 199% close to the elixir, do you understand?" Seeing that Lu Yao had misunderstood, he immediately corrected it.

"Oh, I see!" Lu Yao suddenly realized, and then continued to ask: "Master, since the semi-elixir is an elixir with a concentration of ninety-nine percent of the spiritual energy, is its medicinal effect not much different from the elixir?" ”

"You are wrong again, the reason why the elixir has become an elixir is because it has reached a qualitative leap, although there is only a word difference between the semi-elixir and the elixir, and the concentration of the aura is only one percent different, but in comparison, the effectiveness of the two is very different. Seeing that Lu Yao had misunderstood, he immediately corrected it.

Lijiang patiently explained to Lu Yao, Lu Yao would always ask Lijiang whenever he didn't understand something, the two of you said it sentence by sentence, and after more than an hour, Lu Yao finally understood the truth.

A "half" word, just like a railing hanging in the air, jumped over, it entered the level of elixir, can't jump, it is a semi-elixir, just like the high jump competition, even if you break the world record, but as long as someone jumps even one centimeter more than you, they are still champions, and the new world discipline will still be created by others, and people will always remember the first place, not the second place that you just broke the world record.

The theory is clear, the next thing is to practice, Lu Yao did it according to the dictation of leaving Xinjiang word by word, every step is to keep improving, and dare not be sloppy.

The herbs needed to refine the semi-elixir naturally can't be those very common herbs, if it was before, maybe it would be a big problem, but since Wang Lao cured his old illness and the other party gave him many valuable herbs, everything was solved.

Lijiang taught Lu Yao to refine a semi-elixir called Phantom Dragon Pill, which can make the user have the effect of flying like a dragon for a short time, and its effect is not only to allow the user to fly for a short time.

"Master, how long can this Phantom Dragon Pill make people fly?" Lu Yao asked with a little excitement when he thought that this elixir could actually give him the ability to fly.

"One breath!" The answer to leaving Xinjiang is simple.

"A breath?" Lu Yao was very puzzled, what does the time of flying a breath mean, according to Lu Yao's understanding, in a breath, he has fallen before taking off.

"The dragon breathed thousands of miles, and took the Phantom Dragon Pill, although it can't reach the level of one breath and ten thousand miles, but two or three thousand meters is not a problem, don't underestimate these two or three thousand meters, Yuan Ying Realm, if you want to catch the person who has taken the Phantom Dragon Pill, it is simply a dream." Lijiang said with a smile.

As soon as he said this, Lu Yao immediately became excited again, the time for a breath is very short, but if he can fly two or three thousand meters away in a breath, it is still quite powerful, Lu Yao is now the peak of the Jindan realm, even if he spares no effort to do it, he will only fly out of a distance of hundreds of meters between breaths, what is the concept of two or three thousand meters, then a person in the realm of Lu Yao can fly more than ten breaths for a time.

These ten breaths were enough time for the escapees to regain a lot of strength and return to the battle.

Knowing this, Lu Yao began to take a small section from those herbs according to what Lijiang said, separated them according to the control of the fire and the length of time, and put them into the Qingyun Ding in turn.

Every new starting point will be accompanied by a lot of old or new problems, and the same is true for alchemy, the ordinary elixir Lu Yao is very handy, but when it comes to the refining of the semi-elixir, the problems are still endless. Lu Yao first put half of the hundred-year-old wild ginseng into Qingyunding, and when it was full of overflowing houses, Lu Yao hurriedly threw another section of a three-hundred-year-old ingredient Ganoderma lucidum grass into it.

Lijiang said that ginseng and Ganoderma lucidum grass are both great supplements, and refining them together is easy to cause conflicts, but with Qingyunding, all these things are easy to solve, but even so. When Lu Yao put in the second flavor medicine, Qingyunding still shook violently, and as expected, there were some flaws in the control of heat and time, and the two precious herbs were burned into flying ashes.

The originally rich aroma instantly turned into a pungent stench, which made Lu Yao's eyes hurt, and he forcibly held back his tears to dispose of the ashes of the herb from Qingyunding and poured it into the trash can on the side.

The first failure did not discourage Lu Yao, but aroused the momentum in his heart that he did not admit defeat, adjusted slightly, summed up the lessons of the first failure, and immediately started the second refining.

Although the second time was also a failure, at least Lu Yao made a lot of progress, this time at least until the fourth flavor of the medicinal herb entered the Qingyun Ding, and the Qingyun Ding shook violently again, turning the herbs in the Ding into ashes.

The third time, the progress was still not small, and so repeatedly, Lu Yao tried seven or eight times, and almost exhausted the herbs that Wang Lao gave him, so he barely persevered until the last herb was finally reached.

Lu Yao looked at the only remaining herbs on the table and a layer of fly ash in the trash can, and felt a little inexplicably nervous, this time Lu Yao was not in a hurry to start refining immediately, but closed his eyes and carefully recalled the reasons for each previous failure and some of the things he realized, the first failure was caused by problems with the heat and time control, the second failure was caused by Lu Yao's own nervousness, and the third, fourth and even fifth times were caused by the wrong amount of herbs.

Savoring each failure, Lu Yao gradually calmed down, opened his eyes, picked up the only remaining herbs on the table, put them on his nose and smelled them, and then said to himself: "Success or failure depends on yours!" ”

The voice fell, Lu Yao instantly started the ninth attempt to refine the semi-elixir, the first flavor of medicinal materials into the Ding, no problem, the second flavor of the medicinal materials into the Ding, there is still no problem, the third taste, the fourth taste, the fifth flavor, the medicinal materials in turn, there is still no problem, the room is full of rich fragrance, and the breath that spreads out even makes the immortal qi in Lu Yao's body resonate, and he begins to be eager to try.

Now only the last medicinal herb is missing, and it is also the most critical amount of medicinal herb, and the dragon grass has entered the Ding.
