The Bone Transformation Blood Pill is a second-grade elixir of the ground level, and it is much more difficult to refine than refining the Tempest Snow Melting Pill.

Yun Jianchen started refining, but he failed before he was halfway through refining, either because he didn't control the furnace fire enough, or he put in the spiritual materials too early.

Long Yan would only suggest mistakes to him after he made them.

It was also under Long Yan's teaching that Yun Jianchen gradually gained experience in refining the Ossified Blood Pill.

Yun Jianchen paid not only time, but also fragrant spirit grasses, vermilion jade fruits, and dozens or hundreds of blood-dissolving flowers.

After nearly half a year, Yun Jianchen successfully refined the Birth Ossification Blood Pill.

Long Yan asked him to refine the Bixin Pill again, and the Bixin Pill was also a second-grade elixir, and Long Yan also told Yun Jianchen the recipe for refining the Bixin Dan.

Under Long Yan's guidance, Yun Jianchen spent nearly a month refining this time, and this Bixin Pill was also flawless.

"Very good, you can refine the third-grade elixir of the ground level next, this time you have to refine the seven-star elixir......"

Long Yan set the next goal for Yun Jianchen again, and this time it took four months to refine the Seven-Star Pill Yun Jianchen.

Long Yan asked Yun Jianchen to refine several earth-level third-grade elixirs, and another year passed.

Time flies by like flowing water.

Fifteen years have passed in a flash, and Yun Jianchen's alchemy technique has also advanced by leaps and bounds, and it has also improved from refining the third-grade elixir of the ground rank to the level of refining the fourth-grade elixir of the heavenly rank.

Yun Jianchen's realm also completed a breakthrough during this time, successfully breaking through to the peak realm of the middle stage of the Immortal Monarch.

At this time, Yun Jianchen had already refined several Heavenly Rank Fourth-Grade Immortal Pills.

The cultivation of these Heavenly Rank Four-Rank Immortal Pills also laid the foundation for Yun Jian Chen to refine the Dragon Pattern Pure Heart Pill.

At this time, in the cave, in addition to the spiritual materials needed to refine the Dragon Pattern Pure Heart Pill, the other piles of spiritual materials had already been consumed, and the reason why these spiritual materials could be consumed so cleanly was because Long Yan had set an alchemy goal for Yun Jianchen in a targeted manner.

The elixirs that were refined were all made from existing spiritual materials.

Long Yan looked at Yun Jianchen and said, "Little rabbit cub, your current ability is enough to refine the Perfect Flawless Dragon Pattern Pure Heart Pill, and a Perfect and Flawless Dragon Pattern Clear Heart Pill is enough for you to directly enter the realm of the Immortal Emperor when you are at the peak of the late stage of the Immortal Monarch." ”

"Hmm!"

Yun Jianchen nodded thoughtfully, these years of alchemy experience also gave Yun Jianchen a clearer understanding of alchemy.

With his talent, coupled with alchemy, it was enough for him to step into the realm of Immortal Venerable within a thousand years.

And he is now at the peak of the middle stage of the Immortal Monarch, and Yun Jianchen has stepped into the peak realm of the middle stage of the Immortal Monarch for more than two years, and the precipitation of more than two years has allowed him to vaguely grasp the opportunity to break through to the late stage of the Immortal Monarch.

Yun Jianchen felt that he was about to break through several times, but he was stuck at the critical moment, which made him regret it in his heart.

Now refining the Dragon Pattern Pure Heart Pill, there is no room for mistakes, Yun Jianchen immediately left the other thoughts in his mind behind.

Yun Jianchen lit a fire, and when the water was warm, put the octagonal Xuanbing Grass into the Yang Refining Ding, the octagonal Xuanbing Grass would melt quickly if the temperature was too high, and a lot of medicinal properties would be evaporated, which would affect the final efficacy of the elixir.

If the temperature is too low, the Anise Ice Grass will not be able to melt.

Yun Jianchen controlled the temperature of the furnace fire after all these years of tempering, and it had reached the peak of perfection, and it took a full month to melt the octagonal Xuanbing Grass with warm water.

After the octagonal Xuanbing Grass was all fused into the warm water, Yun Jianchen put the Double Picking Spirit Fruit into it.

The Double Picking Spirit Fruit needs high temperatures, and it is a very high temperature, Yun Jianchen was about to urge the Seven Rainbow Cold Fire to the extreme, under his urging, the Seven Rainbow Cold Fire emitted was not divided into two streams, and an extremely cold intention was consciously shot to the ground by him, and the ground was already outstanding and thick ice.

Another raging flame was poured into the Refining Yang Ding Furnace Fire, and as time went by, the Double Harvest Spirit Fruit gradually melted.

Yun Jianchen put the Nine Grades of Lingzhi and other spiritual materials into the Yang Refining Ding, and after more than half a month, the elixir in the Yang Refining Ding was about to take shape.

"That's when you put the dragon grass in. ”

Long Yan shouted violently.

Yun Jianchen immediately took out the dragon pattern grass from the storage ring space, and the dragon pattern grass wanted to break free, but was thrown into the refining yang ding by Yun Jianchen with one hand, and closed the lid before the dragon pattern grass escaped from the refining yang ding.

The moment the lid was closed, Yun Jianchen heard the thud of the dragon pattern grass hitting the lid of the Refining Yang Ding.

Yun Jianchen sat cross-legged on the ground, separated a consciousness into the Yang Refining Ding, under the control of Yun Jianchen's consciousness, the dragon pattern grass was gradually refined, and the energy formed by the dragon pattern grass was also perfectly fused by Yun Jianchen on the pill that was taking shape.

The originally incomparably white elixir suddenly had more dragon patterns, which looked beautiful and extremely beautiful.

The kind of fragrant smell that emanates from the elixir is quite intoxicating, this is the Dragon Pattern Pure Heart Pill!

Yun Jianchen withdrew his consciousness from the Yang Refining Ding, Yun Jianchen opened his eyes, and Dao essence light burst out from his eyes.

At this moment, Long Yan also opened the lid of the tripod, and the dragon pattern Qingxin Pill slowly floated out from the Yang Refining Ding, and an extremely pure fragrant qi instantly rushed into Yun Jian Chen's nostrils.

Yun Jianchen felt that the energy in his body was about to move, and he felt that the shackles that had blocked him for more than two years were also shaking.

"Next!"

At this moment, Long Yan burst out.

Yun Jianchen immediately reached out and grabbed the Dragon Pattern Qingxin Pill, and a surging fragrant qi turned into energy and immediately rushed into Yun Jianchen's body, and with its help, Yun Jianchen completed a breakthrough again.

From the peak realm of the middle stage of the Immortal Monarch, step into the realm of the late stage of the Immortal Monarch.

A stream of Neji Tailai energy rolled out from the depths of Yun Jianchen's body, and at this moment, Long Yan shouted at Yun Jianchen: "Give the Dragon Pattern Qingxin Pill to this king!"

Without any hesitation, Yun Jianchen threw the Dragon Pattern Pure Heart Pill to Long Yan, Long Yan took out the medicine bottle and put the Dragon Pattern Clear Heart Pill into it, and quickly closed the cap of the bottle.

Yun Jianchen was already on his knees on the ground, devoting himself to the cultivation state, and the fragrant aura of the Dragon Pattern Qingxin Pill was quickly refined by him.

Yun Jianchen was even more absorbing the aura around him, and the aura in the cave was instantly sucked clean.

Streams of pure spiritual energy poured in from outside the cave, and were devoured by Yun Jianchen at great speed, and were refined into immortal yuan power through the primordial spirit and stayed in the dantian.

Time passed, and after nearly half a month, Yun Jianchen finally finished his work, and at this time, he was already at his peak.

At this time, although he was only a late-stage Immortal Monarch cultivator, he was enough to kill the peak powerhouse of the late Immortal Monarch.

"Zhan Bufan, I want to kill you!"

Yun Jianchen opened his eyes suddenly, and a terrifying light flashed in his eyes.

Yun Jianchen stood up from the ground and put the Refining Yang Ding into the storage ring, Long Yan handed the bottle containing the Dragon Pattern Qingxin Pill to Yun Jianchen, and said, "If you want to break through, you can swallow the Dragon Pattern Qingxin Pill." ”

"I'm not going to break through here. ”

Yun Jianchen replied, put away the Dragon Pattern Qingxin Pill, and said: "This is the Thousand Elephant Secret Realm, my breakthrough to the late stage of the Immortal Monarch is enough to attract the attention of the Vientiane Sect, if I break through to the Immortal Emperor Realm, those in power in the Vientiane Sect will feel a sense of crisis." ”

"Yes, if you reach the realm of the Immortal Emperor, I am afraid that even the Hengtian Sect will be alarmed, and at that time, your fate may not be in your own hands, if the Hengtian Sect is alarmed, even this king will not be able to protect you. Long Yan was very appreciative of Yun Jianchen's decision.

Yun Jianchen suddenly bowed towards Long Yan, his expression was unprecedentedly solemn, and he said gratefully: "Long Yan, thank you for cultivating!"

"Huh?"

Long Yan really didn't expect Yun Jianchen to come to this scene, after all, before this, Yun Jianchen had used the Star Luo Immortal Chess spell to rectify him.

He was the prince of the Dragon Clan, and he had been driven crazy several times, so he still had some resentment towards Yun Jianchen in his heart.

Thinking about how to ravage Yun Jianchen in the future, Yun Jianchen staged this show for him, which really surprised him.

"Xiaolonglong, don't hide good things in the future, otherwise I will make your eggs hurt and make you doubt your life. ”

Yun Jianchen said with a cool face.

Long Yan's eyes widened, he couldn't believe that Yun Jianchen was even more shameless than him, and his ability to turn his face like a book was actually stronger than him.

Long Yan forcibly suppressed the roar in his heart, gritted his teeth and said, "Yun Jianchen, why are you so shameless, why are you so brazen......"
