After the treasure ship landed at the gate of the small courtyard, a pair of guards at the peak of Douzun walked out of the treasure ship, led by a guard holding a box the size of a foot, and on top of the box was a purple enchantment made of heaven and earth energy.

"I've seen Elder Lei Dong, this is what you wanted. The guard held the box in both hands and said to Lei Dong with a respectful expression.

Lei shook his head, took the treasure box from the guard's hand, and urged the power of the blood in his body to inject it into the treasure box.

Suddenly, the purple enchantment was like a curtain of water, rippling with faint ripples, and then slowly dissipated.

"Yun Sheng, this is the demon core of the Heavenly Poison Scorpion Dragon Beast you want, as well as the Bodhi Transformation Body Salivation. ”

Lei Dong opened the treasure box, and a dark green diamond-shaped crystal nucleus and a jade bottle of an inch size slowly floated up from the box and landed in front of Gu Xuan.

Gu Xuan stretched out his hand and lightly touched the demon core, and suddenly a pure poisonous fighting qi poured out from the demon core, condensing into a strange demonic beast phantom of an inch size on the demon core, with a dragon head and scorpion body, extremely hideous.

"Not bad. Gu Xuan's right hand slid over the demon core, and this eighth-order demon core was included in the acceptance ring by Gu Xuan.

Then, Gu Xuan's gaze fell on the jade bottle holding the bodhi avatar saliva. As soon as his mind moved, the cork popped out, and a cloud of pale golden liquid floated out of the jade bottle, and suddenly the entire courtyard was filled with an indescribable aroma.

Even Gu Xuan, inhaling a scent, had a sense of tranquility. It shouldn't be a big problem.

"In this way, thanks to Elder Lei Dong, the old man will no longer bother. Gu Xuan said with a smile after putting away the Bodhi Transformation Body saliva .

"Okay, Elder Ben sent Yun Sheng out of Thunder Emperor City. ”

Gu Xuan didn't refuse, and immediately, the two walked out of the small courtyard side by side and walked towards the outside of the Thunder Emperor City.

At the gate of Thunder Emperor City, Gu Xuan turned to Lei Dong and said, "Elder Lei Dong, please stay." ”

"In this way, Yun Sheng is more careful, the soul clan has been very rampant in recent years, if there is any problem on the road, you can ask our clan for help as soon as possible. Lei Dong said with a smile.

Gu Xuan smiled dumbly when he heard this, and the scene was good. After a few more greetings, Gu Xuan set up a clear light and disappeared into the sky.

......

Three days later, the Yunlan Sect was in the sky.

A clear light swept from the sky, ignoring the Yunlan Sect's mountain gate array, and fell straight into the back mountain.

In Gu Xuan's valley, the little medicine immortal was learning various pharmacology and various poison skills with Yao Chen.

As an eight-rank peak alchemist, Yao Chen also has a deep understanding of all kinds of poisons, but it is not a poisonous fighting qi of cultivation, otherwise there will definitely be a notorious poisonous venerable on the Douqi Continent.

Just as the two were talking, the clear light that Gu Xuan had turned into fell into the valley.

"Teacher. ”

Seeing Gu Xuan's figure, the little medicine fairy hurriedly stood up and saluted, feeling a little timid.

"Xiao Yixian continue to learn from your pharmacist, and the auxiliary pills you need to refine and condense the poison pill for the master will be fine soon. Gu Xuan said with a smile, then turned around and walked into the cave.

Looking at Gu Xuan's back, the little medicine fairy's expression was a little confused. She had only been apprenticed for three days, but Gu Xuan was surprisingly interested in her doom poison body. She was inevitably a little moved.

"Xiao Nizi, you know the method of condensing the poison pill by heart. Hurry up and prepare. It doesn't take too long to refine a seventh-order pill, and it won't go wrong when condensing the poison pill. Yaochen behind the little medicine fairy spoke.

"Yes, Uncle Pharmacist. The little medicine fairy nodded hurriedly, and then took out the poison scripture that recorded the method of condensing the poison pill and began to figure it out.

......

In the cave mansion, Gu Xuan manipulated this strange fire, first put the demon core of the eighth-order Heavenly Poison Scorpion Dragon Beast into it, and began to calcinate.

After about a stick of incense, the demon core melted into a dark green liquid under the calcination of the alien fire, and even through the alien fire, you could still feel the ferocious aura revealed in it.

Seeing this, Gu Xuan nodded with satisfaction, and a golden light shot out of his right hand. The golden light fell into the strange fire, turning into a bodhi avatar flowing with golden light.

Under the calcination of different fires, the golden and green masses also began to slowly blend.

After a cup of tea, the Demon Core and Bodhi Avatar saliva finally fused into a dark golden liquid with dark green streamers flowing on it.

"It's not a big problem, prepare Ning Dan. Gu Xuan muttered.

Half an hour later, a gloomy cloud of calamity condensed again in the sky above Yunlan Mountain, and the nine-colored Dan Thunder shuttled and roared among the calamity clouds.

The moment the Dan Tribulation appeared, it alarmed the entire Yunlan Sect.

"Why is this Dan Tribulation a little different?" The disciples of the Yunlan Sect were very puzzled, the Dan Tribulation they had seen before was all purple Tribulation Thunder, but this time the Tribulation Thunder was actually nine colors.

"Nine Colored Thunder, could it be that the old sect master's alchemy is one step closer?"

"Oh, ignorance. This is the Danlei of the Eight Pins of Pills, and the Danlei of the Eight-Pins of Pills has a total of nine colors, and each extra color is the difference between cloud and mud. ”

Just when many disciples of the Yunlan Sect were speculating that the old sect master had refined a few grades of pills, a giant palm that covered the sky and the sun emerged, directly scattering the calamity clouds in the sky.

......

Back mountain valley.

I saw Gu Xuan walking out of the cave with a small jade bottle in his hand.

Yaochen and Xiao Yixian, who were waiting outside, saw Gu Xuan's figure and greeted them together.

"The auxiliary elixir has been practiced. As for condensing the poison pill, you can only look at yourself, and being a teacher can't help you anything. Gu Xuan looked at the little medicine fairy and said.

"Teacher......" The little doctor fairy opened his mouth to say something, but the words came to his mouth and swallowed back.

Gu Xuan looked at the expression of the little medicine fairy, and roughly understood what this little girl was thinking.

"Child, being a teacher is your teacher, and you don't need to see the teacher. If one day the teacher is gone, you can remember to protect this Yunlan Sect for one or two. Gu Xuan deliberately had a kind look on his face.

"Yes, teacher. The little medicine fairy nodded, took the pill in Gu Xuan's hand, and returned to the cave next to her, which she opened by herself, and retreated to Ning Dan.

"After all, he is also an important character in the original book, although the plot has changed, it shouldn't be a big problem to condense a poison pill. Gu Xuan said silently in his heart.

"What is Brother Yun thinking?" Yaochen next to him looked sideways at Gu Xuan.

"I didn't think about anything, I was just worried about the process of condensing the poison pill for this Nizi. Gu Xuan smiled and said.

If Gu Xuan wants to say that he has any feelings for the superficial disciple of the little medicine immortal, it must be nonsense. But whether the little medicine fairy can control the poisonous body of doom is related to whether his trip to the ancient poison Ze is smooth.

After all, it is a legacy left by the Ancient Dou Emperor, and there is nothing good, even if there is nothing, he can get a netherworld poisonous fire that has been cultivated for thousands of years.

Devouring this strange fire can at least improve a certain amount of cultivation.
