Although there is a gathering array, Lu Bu still does not take it lightly.

The second step, which is the most complex and cumbersome step, is also the most error-prone step, which is the batching of the main materials.

From the Tenth-Order Xuanzhu to the Climbing Heavenly Fruit, each of the main materials undoubtedly contains powerful energy, and all of them have extraordinary characteristics. Grasp its characteristics, supplemented by reasonable rational calculations, and use the most appropriate refining techniques at the most appropriate time to add to the auxiliary material puree.

This kind of work requires a high level of concentration, superior logical computing skills and a strong ability to grasp the timing.

The auxiliary material puree is in a state of continuous refining from the beginning, if it is described as porridge, that is, the moisture disappears little by little, and the puree appears to be thicker and thicker.

It can be said that every dry and humidity of the puree is unique and instantaneous. Once this degree is not grasped well, then every small mistake will increase the success rate of the elixir refining.

Burning Flame had originally sweated for Lu Buqi in this link, but as time went by, it found that its worries were really unnecessary, because Lu Buqi did a very good job and did not make a small mistake.

Lu Bu is a person who strives for perfection in things, has extremely high requirements for himself, and has strong control ability.

zuihou Pantian Fruit and Earth-Covering Spirit Vine were also added to the puree, and under the exercise of the powerful five-color true fire, one gold and one silver were wrapped in two rays of light, leaving Zuihou a small group of elixir puree, just like a double dragon playing with pearls.

At this time, it has entered the third step of the Nine Transformations Back to Heavenly Pill refining, which is the very critical stage of Cheng Dan. The Chengdan stage is divided into Judan stage, Ning Dan stage and Lidan stage.

When the gold and silver dragons had completely penetrated into the bamboo, and all the materials had been smelted into a mass of chaotic-colored elixir puree through various methods, Lu Buqi had played hundreds of magic decisions one after another, only to see that the dense remaining pill qi in the reactor began to turn into a tornado-like vortex.

The vortex was centered on the chaotic-colored elixir puree, rotating at high speed, and as time went by, it was found that the darker gas seemed to be forced into the outer circle by centrifugal force, while the lighter gas was reattached to the elixir puree because of the centripetal force.

When all the high-speed pinching techniques were suddenly collected, Lu Buqi let out a low cry of "condensation" in his mouth.

All the light-colored gases attached to the elixir puree, like water seeping into a sponge, suddenly submerged into the elixir puree, and then it was found that the elixir puree absorbed these gases not only did not expand, but began to shrink.

If you analyze this shijie pill with the scientific and technological instruments of Lu Buqi's previous life, you will find that the most dense metal osmium cannot be compared with it, and all the very pills are actually very heavy and hard.

At the very least, if you use pure stomach acid to laugh at the elixir, it is extremely ridiculous, just like no one can laugh at a piece of steel.

Of course, the density of different pills is obviously not the same, and different alchemists have different strengths that can compress the pills because of their different abilities.

When the pill puree completely lost its liquid state and turned into a completely solidified ball pill blank tire, Lu Buqi sighed again in his mouth: "Change!"

This sound change, as if by magic, suddenly began to deform the mass of pill blanks, changing at a speed and in a way that was overwhelming, sometimes round, sometimes edged, sometimes long and sometimes short.

This change continued, as if there was a struggling little life in the womb of this pill blank.

It wasn't until a long time had passed, and the magic crystals that formed the gathering array had been replaced in four batches, and Lu Buqi finally performed his self-created Bagua Opening Furnace Method.

Of course, before this moment, in the stunned but expectant gazes of the four of Elma, Long Buli, Long Buregret, and Princess Yu'er, Lie Yan had already tacitly ingested Lu Buqi into the Miaoluo Water Hell along with the formation and the Dan Furnace.

The Liliang of Miaoluo Water Prison can be vividly reflected as long as the furnace is opened.

The turbid Dan Qi that suddenly rose up, like a small mushroom cloud, quickly merged and dissipated in the dense blue light.

"Human cub ......" Burning Flame was a little excited.

Lu Buqi's mood was quite calm, he could feel that the pill was very perfect at the moment of final separation and complete forming, and when the furnace was opened, the situation was also very stable.

However, to say that there was no nervousness was also a lie, but when Lu Buqi saw with his own eyes the five gold and silver two-color Guanghao circulating pills lying in the residue, he finally breathed a sigh of relief.

"Refining five Nine Turning Heavenly Pills at one time, this is the record of Xuan Qian Dongtian!" This may be the reason for the excitement of the Burning Spirit.

The output of the pill is affected by the sum of the energy of the raw materials, and there must be an upper limit, and Xuanqian Dongtian, as a space that can "slaughter the gods", there must be countless powerful alchemists, but at most, only five are refined, it can be said that Lu Buqi played absolutely perfectly this time.

Lu Buqi carefully put away the Nine Turns Back to the Heavenly Pill, and then he started the alchemy program of Xianyou Ding again.

What Lu Buqi had to do was to return the slag left by the refining nine to the Heavenly Pill for re-refining. In the refining of the Nine Turning Back Heavenly Pills, there will be no associated pills, but the residues can also be refined into a holy medicine that heals injuries and detoxifies, called Jiyuan Dan.

The refining of the Extreme Yuan Pill is quite simple, and it is basically a process of condensation and separation.

Although the harvest of one hundred and eleven Extreme Yuan Pills was far from the value of the five Nine Turning Back Heavenly Pills, it made Lu Buqi equally happy, after all, the Extreme Yuan Pill was placed in the Xuanqian Cave Heaven, but it was also a very popular and useful pill.

Miaoluo Water Prison was lifted, and Lu Bu, who was guarding the root of life, reappeared, and felt several pairs of concerned eyes.

When he started alchemy, in addition to Elma, he broke through his forgetfulness and wings in the innate spirit fetal placenta, which was also counted on the side. And now, unless there are three of them, Long Bu Li, Long Bu Regret and Princess Yu'er are also here.

"It seems that this alchemy really took me a lot of time. Lu Buqi smiled lightly.

Indeed, the refining of the Nine Turning Back Heavenly Pill took Lu Buqi ten days, ten days of sleepless and highly concentrated, which should have made a person very tired, but Lu Buqi seemed to be in very good spirits.

As soon as Lu Buqi appeared, the four girls asked almost in unison, "How is it?"

"Judging from the door master's expression, it should be done, right?" Tengyi's wrinkled eyes fluttered slightly.

Lu Buqi said with a smile: "That's right, it's done, and you have successfully refined five Nine Transformation Heavenly Pills!"

"Great!" While everyone cheered, Long Buli and Long Buli hugged each other excitedly, and Long Buli said with emotion: "Yunqin has been lying for so many years, and she can finally wake up." ”

Long didn't regret it, and he couldn't cry: "Yes...... The wish not to abandon the eldest brother has finally come true, and now it's good......"

Lu Buqi was also very happy, he was already a little impatient to return to the old Yunyin City and give Yunqin the Nine Turns Back to Tiandan, he couldn't wait to see what kind of expression Yunqin would look like when he "came back from the dead".

However, Lu Buqi didn't only have Yunqin in his mind, he still remembered the breakthrough of Forgetfulness and Tengyi: "How are you guys, the innate spirit fetal placenta is easy to use?"

"It's so easy to use!" "The unsentimental mouth is about to grin to the back of his head: "In the past, if I wanted to sprint to a higher demon path, and wanted to transform the soul body of the demon soul crystal, I always had a feeling of being powerless, but in the innate spirit fetal placenta, there was no psychological burden at all, and I felt that my perception of the demon path had improved a lot, the soul body." ”

Teng Yi also nodded again and again: "Yes, as if the shackles of a thousand years have been completely lifted, I think this spiritual breakthrough is simpler than my last time." ”

Lu Buqi smiled: "So, the strength of both of them has improved?"

"Of course!" "Of course!" "Forget the smile from ear to ear: "Door Master, if it weren't for the law, I'm afraid you wouldn't be my opponent now." ”

It's not wrong to say that he is forgetful, before he broke through the new demon path, he was already equivalent to the cultivation strength of the Great Perfection of the Gathering Peak Period, and after breaking through, he was basically the same as the Divine Infant Monk of the Rebirth Realm.

Although Lu Buqi's original basic strength is one or two points stronger than that of forgetfulness, if he does not explode the yuan, Lu Buqi will definitely not be the opponent of forgetfulness.
