The secret room was empty. One read the book ■ 〈◇ to.〈1_K book A ° CN 〈 S one H read U book .□

Hong Yu was in the space inside the Xuantian Tower, and the tenfold flow of time flowed around his body.

Hong Yu has been sitting here for more than ten days.

In the past ten days, Hong Yu has been refining the elixir.

The materials of the Crossing Er Pill and the Ascension Pill were all rotating wildly in the Nine Dragons Void Heaven Ding, and as Hong Yu controlled the Nine Dragons Void Heaven Ding, the entire body of the Ding burst out with bursts of dazzling light, which was extremely gorgeous and gorgeous.

"Buzz!"

Hong Yu pinched the seal with both hands.

The seal recipe is ever-changing, but in his hands, it seems to be at ease, as if it has been cast thousands of times.

As the seal technique played out one after another, it entered the Nine Dragons Void Heaven Ding.

Blood-colored dragon patterns circulated on the Nine Dragons Void Heaven Ding, and the terrifying Danding flames were like a furnace of fire, frantically calcining the countless medicinal materials in the Ding.

The flames were blazing.

But at the same time, it's very gentle.

It is able to mediate itself according to the different habits of various medicinal materials.

It can not only smelt the medicinal materials and remove impurities, but also preserve the purest purification energy of the medicinal materials in the most appropriate way and degree.

The fragrance is fragrant and tempting!

Before it became a pill, there was a medicinal fragrance spreading, which was the characteristic of the elixir above the sixth order!

"Eighteen Butterfly Hands!"

Hong Yu snorted softly.

The light on his body burst out, wrapped in brilliant golden light, surrounding his body, making De Hongyu like a golden god, with a thunderbolt, thunder, sacred and inviolable.

Gentle power poured out from the palm of his hand.

Condensed into one gorgeous butterfly after another.

This is the mystery of the mysterious alchemy method "Eighteen Butterfly Cloth Hands" that Hong Yu is currently performing, which can personify energy into the form of a butterfly and fly into the tripod.

Just like a butterfly taking pollen, it once again purifies the essence of these extremely spiritual medicinal herbs!

It has been recorded in the Divine Pesticide Codex: between heaven and earth, inside and outside the five elements, and in the universe, there is no absolutely pure material. ※ One Reading Book Book □.Book 1〈

The Earth Spirit Realm thinks that it is a pure material, but the Earth Spirit Realm is not strong enough to show the impurities in it!

The Supreme thinks that it is a pure material, but the strength of the Supreme is not enough, and it cannot show the impurities in it, and it is pure when it thinks it is!

Even though the essence of the medicinal materials after the purification of the Nine Dragons Void Heaven Ding can already be called extremely pure, Hong Yu will still purify it a second time, and with Hong Yu's eyesight, he can naturally see that among the medicinal essence of the Dingzhong, there is a little bit of black, extremely delicate air flow slowly rising, slowly dissipating between the void.

"Whew!"

It's a very difficult and mind-consuming process.

Hong Yu maintained the "Eighteen Butterfly Clothes Hand" for half an hour before the second purification of the medicinal materials was completed.

However, Hong Yu did not let up because of this.

The process of alchemy has three steps: smelting, purification and the most critical condensation!

At present, the first two steps have been completed, and only the last step is left, and whether it becomes a Dan depends on this step!

"On weekdays, it is rare to refine a pill with all our might, and it is all done by relying on the Nine Dragons Void Heaven Ding to automatically refine the pill. I didn't expect that this wholehearted refining of the pill would be so exhausting and exhausting. However, this kind of wholehearted refining process can actually have a promoting effect on spiritual power, which is not bad!"

Hong Yu exhaled softly, his eyes flashed, and he pointed at Danding with both hands: "Give me Ning!"

"Buzz!"

The Nine Dragons Void Heaven Ding trembled violently, and the pure medicinal essence instantly squirmed, bursting out with bursts of fragrance.

It was originally a mutually exclusive medicinal essence, but under Hong Yu's guidance, it slowly squirmed and fused together.

The entire Nine Dragons Void Heaven Ding was trembling.

Half an hour passed, and the tremor slowly stopped, and the lid opened on its own with a "boom".

As if a treasure sac opened its mouth, the sound of "whoosh" broke through the air, and the shadows of the elixir shot out from the Nine Dragons Void Heaven Ding, swirling in the air.

Guided by spiritual power, Hong Yu distinguished the two elixirs and put them in a jade bottle. A look at the book ― read the book.一1 look at K°CA◆N◆S_H book U〈.―c〈c

"Whew!"

Hong Yu wiped the sweat stains on his forehead, a hint of joy flashed in his eyes, and he muttered: "Not bad, there are thirty-six Crossing Pills and ninety-eight Ascending Spirit Pills!"

Putting the jade bottle away, he looked at the few storage rings in his hand.

He had already selected the elixir for refining the Nine Turns Resurrection Pill from among them, and this was thanks to the great harvest in the Feather Immortal Valley, otherwise many of these elixirs were extinct in the outside world, and it would be impossible to refine the Nine Turns Resurrection Pill at all!

"Tianluo Ma Vine, Xuanjin Grass, Eight-foot Ginseng ......"

The same incomparably precious elixir was put into the Nine Dragons Void Heaven Ding.

The blood dragon text on the Nine Dragons Void Heaven Ding was running again, holding its chest high, soaring through the clouds, like a group of dragons dancing, cheering and jumping.

Countless energies flew towards Dingzhong.

Tianluo Ma Vine is one of the main elixirs, it is very difficult to refine, even if it is burned with the white light of the pure world, it will take a long time to melt it, let alone purify the medicinal essence in it.

Hong Woo can only drip into it with his own blood.

Refine it with blood.

Under the smelting of the essence blood, the Nine Shadows Burning World Flame and the Nine Dragons Void Heaven Ding's own Ding Fire, the progress was much faster.

In the continuous smelting, clumps of pure medicinal essence were quenched.

A cloud of essence burst out of Hong Yu's eyes: "The most important thing in the refining of the Nine Revolutions Rising Pill is to grasp the heat of the fire, the flame cannot be too weak, if it is weak, even the slightest difference will make the purification uneven, resulting in a drastic decline in the efficacy of the pill." If it is too strong, it will destroy the essence of some of these fragile elixirs. It has to be controlled at a balanced level!"

The mixed information recorded in the Divine Pesticide Codex has long been familiar to Hong Yu.

With his current strong strength, it is also extremely laborious to make such a subtle adjustment.

Fortunately, Hong Yu's will is strong, and the strength of his consciousness is comparable to the limit of the Great Emperor, so he can complete this kind of regulation.

Over time.

In the blink of an eye, another eight days had passed in the Xuantian Tower, and there were no more complete medicinal materials in the Nine Dragons Void Heaven Ding, and all of them had turned into medicinal essences.

The surging and fragrant medicinal aroma is transmitted.

Fluttering in the wind, lingering!

"It is worthy of the Nine Rank Divine Pill, just the purification of the essence of medicinal power, it is enough to perform nine times and eighteen butterfly clothes to reach the extreme. Hong Yu let out a long breath, this refining Nine Turns Rising Pill is much more tired than before.

Previously, a large part of the procedures were completed by Jiulong Xutianding himself.

These nine turns of the Rising Pill are from beginning to end, and they need to be completed by themselves, and the difficulty can be imagined!

"The essence of the sun and the moon, the refinement of the universe, the eight desolations, the six ascending ......"

Hong Yu recited the Ning Dan mantra in his mouth.

The Ning Dan of the Nine Rank Divine Pill is naturally not simple, it needs to introduce a powerful law power to maintain the balance between various anti-heaven elixirs.

Otherwise......

Just fusing the medicinal essence together, this can't be called a supreme-level divine pill!

"Boom!"

The entire Nine Dragons Void Heaven Ding was trembling.

The power of the law is counteracting the repulsion between the medicinal essences, but fortunately, with Hong Yu's strong blessing, the resistance of these medicinal essences is getting lower and lower!

The whole process lasted seven days and seven nights!

When the eighth day comes......

"Boom!"

A terrifying roar came from within the Nine Dragons Void Heaven Ding, and the nine blood-colored dragon patterns flickered and dimmed, as if they couldn't suppress the irritable medicinal essence.

Fortunately, Hong Yu was prepared.

Behind him, the Heaven Devouring Demon Elephant suddenly burst out, the Law Xiang took off, and the huge nose firmly stabilized the Nine Dragons Void Heaven Ding, and a strong force swallowed out from Hong Yu's hands, converging into a silver river, penetrating into the Ding.

It is like a huge iron chain, condensing the essence of medicinal power together.

"Boom!"

The Nine Dragons Void Heaven Ding opened his mouth suddenly, and a nine-colored pillar of light rushed out of it, heading straight for the sky.

"Buzz!"

The pillar of light reached the top of the Xuantian Tower, and after a slight shock, it exploded with a "boom", and the nine-colored spots of brilliance were sprinkled like rainbow rain, falling in all directions, shining on this side of the world, making the sky brighter and brighter.

Nine-colored brilliance shrouded in it.

Three Nine-Turn Rising Pills slowly flew out of the ding, and they seemed to have a spiritual intelligence, trying to escape and leave.

But how could Hong Yu allow the elixir that he had worked so hard to refine to escape?

"Give me back!"

The huge nose of the Sky Swallowing Demon Elephant sucked violently into the air, forming two rounds of black holes, swallowing the three pills directly and returning them to Hong Yu's hands. Letting the three pills jump in his palm, Hong Yu snorted coldly, condensed a law jade bottle with the power of the law, and put the three pills into it, which was a big sigh of relief.

"It's finally done!"

A gleam flashed in Hong Yu's eyes, and he immediately stood up and left the space in the tower.

He summoned Huhu, Su Linfeng, Huo Que, Tarosa, Federle and other strong people who were loyal to him.

Huhu's current cultivation has reached the three-turn arcane realm, and Hong Yu directly gave this little guy six Erdan.

With its physique, if taken directly, it can fully withstand the terrifying power of this elixir.

As for the others, except for the Tarosa with the Chaba snake as the body, three of them, the rest were all one of the Edan.

It's not that Hong Yu is stingy, it's really that their bodies can't withstand such a terrifying elixir.

Then hand over the Nine Turns Back Pill to Su Linfeng, and Hong Yu told everyone to retreat and take the pill.

For the next two days.

Terrible thunder clouds appeared one after another in the sky above Hongyu City, and the terrifying thunder fell from the sky, roaring endlessly, making Hongyu City full of wind and rain, and countless people were sincerely afraid and worried.

Some people even believe that this incessant thunderstorm is a curse!

For all this, Hong Yu naturally didn't care.

These thunder tribulations are just normal thunder tribulations that everyone took pills to break through the realm and attracted, not a curse!

And with the passage of time.

On the third day, shortly after the most terrible thunderstorm finally disappeared from the sky above Hongyu City, everyone ended the retreat together.

At the same time as they were out of customs.

Outside Hongyu City, a group of murderous powerhouses also happened to arrive......
