Chu Dupan sat in the empty room, he was studying and trying out the potion, and Qing Ning and Dudu were around to protect the Fa.

A drop of blue elixir hung in front of Chu Duan, exuding a mysterious luster, which was completely different from the pill of the Tianjun Great World. Chu Duan's ten fingers were like butterflies piercing flowers and leaves, and runes the size of rice grains were born at his fingertips, and then submerged into the blue potion.

Dan Weng led Chu Duan into the Dan Dao, but in fact he did not teach Chu Duan any specific alchemy, but taught him the essential truth of the Dan Dao.

Compared with specific alchemy, the essence of the Dan Dao is the fundamental, and the secret techniques of alchemy are just minutiaries.

Dan Weng taught Chu Dui Dan Dao, and the specific alchemy still depends on his own understanding, Tiannong's medicine hand, mixed yuan forbidden method, forbidden spirit method, etc. are all obtained by Chu Dui's own enlightenment.

With the improvement of Chu Duan's cultivation, these Dan Dao secret techniques that he had comprehended on his own were once again refined by him, and at this time, he was analyzing the medicinal properties of the medicine with Tiannong's medicinal hand.

The potion made by the scientific and technological civilization was different from the elixir, and Chu Duan could not define the grade of the elixir, but he analyzed that the elixir of this elixir was extremely strong, even stronger than the medicinal power of the Heavenly Jun Great World Dao Rank Pill.

What's more important is that the effect of this elixir is very strange, it is aimed at the physical body, and it is not the strength of the physical body that is enhanced, but the essential power of the physical body.

After a moment of silence, Chu Duan opened his mouth and swallowed the drop of blue elixir in his mouth, he wanted to experience the power of the elixir for himself. The blue potion entered the abdomen, and a sweet medicinal fragrance filled the mouth, and then the medicinal power began to be released.

Streams of medicinal power submerged into Chu Duan's limbs, and the feeling was like the whole body being wrapped in soft feathers, a little itchy, and a little warm.

Chu Duan's eyebrows glowed, and his star-like divine consciousness enveloped his body, and the subtle changes in any part of his body could not escape his perception, and he was observing the effect of the potion on the body.

The gold and silver sun and moon god patterns naturally appeared, and Chu Duan's heart was beating violently, like a beating war drum, and the blood was rolling around.

In Chu Duan's heart, a cloud of sun and moon divine blood rolled, becoming more and more powerful under the effect of the elixir. The surging blood and qi gathered behind Chu Duan and turned into a round of the sun and a round of bright moon, the big sun shone on the heavens, and the bright moon swayed the earth.

Qing Ning's face changed slightly, he could feel the strength of Chu Duan's blood qi at this time, and he was becoming more powerful.

Chu Duan raised his head to the sky and let out a long roar, the momentum on his body suddenly rose a lot, there was a crackling sound of bones on his body, and a pillar of blood and qi light rose to the sky above his head.

"Blood and wolf smoke, flesh and body divine element!" Qing Ning's pupils contracted, and his face changed slightly.

Qingning's predecessor was to kill the empress, even if he is in trouble now, he still has knowledge. The pillar of blood qi light above Chu Dui's head is called Blood Qi Wolf Smoke, which is an anomaly produced by the refinement of the body cultivation to break through to the Divine Yuan Realm, at this time, Chu Dui's refining cultivation is the first to break through, and with the help of the power of the elixir to reach the Divine Yuan Realm.

The bloody wolf smoke naturally won't make Qingning change color, what really made her change color was that the bloody wolf smoke was too unusual and too thick.

The blood qi wolf smoke of ordinary body refining cultivators when they broke through the Divine Yuan was about the thickness of a bowl, and the more powerful ones could be the thickness of a bucket, but at this time, the blood qi wolf smoke above Chu Duan's head was two zhang thick, even when the emperor-level body refining cultivators broke through, there was no such vision.

Chu Duan's face under the bloody wolf smoke was not good-looking, and drops of hot sweat on his forehead hit the ground, and he was under tremendous pressure at this time. Chu Duan completely underestimated the power of the potion, originally he thought that the power of a drop of the potion, not a lot, with his strength was enough to suppress it.

However, the power of that drop of elixir was beyond imagination, and Chu Duan's breakthrough through the Refining Divine Yuan had only consumed less than thirty percent, and there were still seventy percent of the elixir that was continuously exerting its effect. At this time, Chu Duan's body cultivation rushed all the way from the early stage of the Shenyuan First Heavy to the Consummation, and even advanced towards the Shenyuan Double Stage, which was not a good thing.

A swishing sound landed on top of Chu Duan's head, and he received Chu Dui's summons, and the Dudu that landed on top of Chu Dui's head shared the power in Chu Dui's body. Dudu has Chu Duan's natal imprint in his body, and he can directly share the power in Chu Duan's body through the natal imprint and share the pressure for Chu Dui.

Dudu retracted his wings and honestly lay on the top of Chu Duan's head, the dark light on his body was circulating, and his breath was rising. The crimson flames burned on Dudu's body, and his cultivation took a step further and began to pass the sixth Nirvana tribulation.

During the previous five Nirvana tribulations, he died and came back to life, and each time he was in tears, but this time it was unusually quiet, as if he was asleep.

After a while, the flame of Nirvana was extinguished, and Dudu's sixth Nirvana Tribulation was easily passed, and his cultivation continued to improve, and the seventh Nirvana Tribulation came in an instant.

There were no accidents, and the seventh Nirvana tribulation was easily passed, and I fell asleep without feeling anything at all. Then the eighth and ninth Nirvana Tribulations came one after another, and the aura of Dudu was too powerful, approaching the Shenyuan Duo Giant that Qing Ning had killed.

The sleeping doodoo suddenly shook his wings, the thunder pattern on the wings glowed, and a large cloud of black electric light crackled in all directions.

Qing Ning's face changed drastically, and her body retreated violently before she dodged the black electric light, she sensed that if she was hit by the black electric light, I am afraid that she would be severely injured.

"What kind of power is that?" Qing Ning was shocked in her heart, with her vision and knowledge, she couldn't even see the heel of the black thunder light.

At this time, Dudu had gone through nine Nirvana Tribulations, and he had surpassed Qing Ning in the realm, and the black thunder light just now made Qing Ning unable to see through it.

Qing Ning glanced at Chu Duan, who was still sitting cross-legged on the ground, and without hesitation, his figure flashed in front of Chu Duan. She naturally didn't want to harm Chu Duan, her soul origin was in Chu Duan's hands, and the two of them had already been both prosperous and loss-making.

At this time, Qingning appeared next to Chu Dui to get a piece of the pie, and she also had Chu Duan's natal imprint in her body, since Dudu could share the power of the potion from Chu Dui, she could naturally do it too.

Chu Du's promotion to the Divine Yuan Realm consumed the power of three percent of the elixir, and Dudu spent four Nirvana Tribulations in a row and consumed the power of three percent of the elixir, and there were still forty percent left at this time. The power of the forty percent potion is already beyond Chu Duan, he can use the Qifu Cave Heaven to suppress the elixir, and then use it slowly in the future.

However, since Qing Ning begged for it, he naturally would not refuse, Chu Duan has never been a stingy person, especially when he treats his own people.

Chu Duan knew the details of Qing Ning, and sent out all the remaining forty percent of the power of the elixir, and Qing Ning passed the ninth Nirvana Tribulation in an instant, and rushed towards the Divine Yuan Realm.

Qingning manifested the body of the god-killing vine, the god-killing vine soared, the main vine became thicker and thicker, and mysterious lines appeared on the vine. More and more vine leaves grow, and each vine leaf has a shiny circulation, and the edges of the vine leaves are blood-red, as if soaked in blood.
