Xiaoyun Palace, underground medicine refining room.

Following the direction pointed by Feng Haoyu, Si Xueyi opened a stone door and walked down, passing through a thirty-meter-long corridor.

Finally arrived at the underground alchemy room.

Si Xueyi saw at a glance the huge alchemy furnace in the alchemy room, and below the furnace was a flame connecting the earth veins.

As soon as I glanced at it, I saw a variety of sorted medicinal materials hanging on the wall shelves, and there was a dazzling array of everything.

"This place is not bad. It's similar to what the old man said. It can save a lot of trouble. Xiaobai, what do you think?"

Si Xueyi looked satisfied and asked Bai Yixuan's opinion.

Bai Yixuan flew out of Tianshang, looked around, and said: "It's okay. It's enough to refine the Holy Dragon Pill. It's just that the flavor of this pill furnace is missing."

"How to say?"

Si Xueyi said curiously.

Bai Yixuan explained briefly: "The alchemy furnace has a grade, which is divided into four grades of heaven, earth, black and yellow, just like martial arts. This pill furnace is only a mysterious grade. If an ordinary alchemist is not able to refine the Holy Dragon Pill, it will easily explode... But if you do it differently...

It’s me, it’s not a big problem.”

Si Xueyi smiled and said: "It took me a long time just to boast."

Bai Yixuan looked at the alchemy furnace and said: "What I want to refine is the Holy Dragon Pill. If there is a slight mistake, the dragon energy will explode the alchemy furnace. Let me first see what grade this earth fire is..."

After the words fell, Bai Yixuan pointed a finger, and the bottom of the alchemy furnace burst into flames.

A heat wave hit me, and the temperature in the medicine refining room suddenly increased sharply.

"Dean Feng is not exaggerating. This earth fire is enough to melt the dragon's blood."

Bai Yixuan stretched out his hand and motioned to Si Xueyi to give him the dragon's blood.

After taking it, he looked at it and frowned slightly: "There are too many impurities and the grade of blood is very low. I'm afraid it will be difficult to refine the Holy Dragon Pill of good enough quality."

As he spoke, he poured the dragon's blood into the alchemy furnace.

The jade bottle doesn't look big, but dragon's blood is falling continuously.

With the injection of dragon's blood, the alchemy furnace burned and exploded like a raging fire cooking oil, and the already terrifying heat wave surged again.

"The heat is still not enough."

Bai Yixuan formed a seal with one hand and controlled the ground fire under the alchemy furnace to continue burning, continuously increasing the temperature of the alchemy furnace.

Finally, five pounds of dragon blood was poured into the alchemy furnace.

Goo-goo-goo!

The dragon's blood gradually melted and expanded, filling the alchemy furnace little by little, and at the same time, an extremely unpleasant smell emerged from the alchemy furnace.

Bai Yixuan frowned slightly and said: "The sources of these dragon blood are very mixed. They are various dragon blood monsters, such as dragon apes, dragon lizards, dragon vultures... Their dragon blood is already thin, and with many impurities, it also

If they are mixed together, it will take a long time to refine them until they are pure."

Whoosh whoosh!

The various medicinal materials on the far wall shelf were put into the alchemy furnace in an orderly manner by Bai Yixuan. He was refining the medicine while talking to Si Xueyi.

"Approximately how long will it take."

Si Xueyi asked.

"It will take about three days. I will try to help you refine five Holy Dragon Pills. It should be enough for the Dragon Prison Holy Elephant Secret to break through to the first level."

Bai Yixuan analyzed calmly.

"Okay, you're busy, I'll go into retreat first to stabilize my cultivation. This place is nice, and the aura is several times stronger than where I live."

Si Xueyi looked at Bai Yixuan's familiar appearance and knew that he had found a treasure.

"Hehe, it's good to have an old man who can practice alchemy well." Si Xueyi said with a smile.

"I'm not an old man." Bai Yixuan turned around and glared.

Si Xueyi smiled and found a place to sit cross-legged.

When the Dragon Prison Holy Elephant Technique was activated, his body glowed with cyan light, and a steady stream of spiritual energy from heaven and earth merged into his body.

After flowing through the limbs and bones, it merges into Zifu and turns into a light rain.

Zifu is now a swamp, and the dragon lotus seedling in the center has only two green leaves and looks extremely immature.

The little green leaves greedily devoured the spiritual rain. After a while, it absorbed all the spiritual rain, and then swallowed up a large amount of pure essence, which then flowed into Si Xueyi's body through the meridians.

Breathing in and out forms a perfect cycle.

"This Longlian is really overbearing. His cultivation speed is much faster than my previous life."

Si Xueyi said secretly in his heart: "Try it in three days to see if you can break through the realm of true soul."

The three realms of Zhenxuan are Zhenyuan, Zhenling and Zhenhun.

Si Xueyi is now at the peak of the true soul. Logically speaking, he must stay in this realm for at least three months before he can try to break through to the true soul.

But with the Dragon Prison Holy Elephant Technique, Si Xueyi thought, there was no need to be so reasonable.

Time passed and Si Xueyi had been practicing at this alchemist for three days.

this day.

Suddenly, the roar of true energy came from within Si Xueyi's body, the green light on his body kept flashing, and even his complexion changed.

Bai Yixuan looked back when he heard the movement and murmured: "Are you going to attack the true soul realm?"

This roar lasted for about half a quarter of an hour before Si Xueyi slowly opened his eyes and exhaled a long breath of turbid air.

"It failed. The three realms of Zhenxuan. This realm of True Soul is a little more difficult."

Si Xueyi sighed and said: "Previously, the true energy impacted the true spirit, and it took almost half a day to complete it."

Bai Yixuan said lightly: "That's because you refined many pills in the Xuanlong Tower. Otherwise, how could you have such an easy breakthrough to the True Spirit Realm? You don't even think about how long it took for you to advance to the True Spirit Realm, ten days

There’s no time.”

Si Xueyi smiled and did not refute. He raised his eyes and said, "Aren't you here? How are the preparations for the Holy Dragon Pill?"

He stood up and walked towards Bai Yixuan, with a trace of expectation in his eyes.

Bai Yixuan was right. The time for him to advance to the True Soul Realm was too short. Without external assistance, it would be difficult to reach the True Soul Realm in a short period of time.

Bai Yixuan said: "The furnace hasn't been started yet, I'm just waiting for you."

boom!

The moment the top cover of the alchemy furnace was opened by Bai Yixuan, dragon energy spurted out, and then the aroma of medicine filled the air, refreshing the heart and mind.

Si Xueyi looked intently, and saw the dragon's energy turning in a circle and pouring into the elixir suspended at the mouth of the furnace.

A pale golden pill, exuding a slight luster, appeared in Si Xueyi's field of vision.

Whoosh!

Si Xueyi reached out and took the elixir from the air.

At a glance, there are three lines on the perfectly smooth elixir that are particularly clear.

Si Xueyi's eyes lit up and he exclaimed: "If I remember correctly, the value of the elixir will double with each additional stripe. The most perfect one is seven stripes, which can only be met by chance."

"It would be as difficult as climbing to the sky to refine one path just by relying on low-grade dragon blood and Xuan-grade pill furnace. You have actually refined three paths."

Bai Yixuan came over and said: "There is a saying that there are impurities in elixirs. If they are taken for a long time, the residue will accumulate in the body. Over time, erysipelas will form. In the least, the five internal organs will be destroyed, and in the worst case, the cultivation will be completely useless."

"The more pill patterns there are, the fewer impurities. The quality of this dragon's blood is too low, and the earth fire and pill furnaces are not very good. Refining to three lines is already the limit. As long as it is a little better, I will have no problem refining five pill lines."

big."

Si Xueyi smiled and said: "As expected, it was taught by the Dragon Emperor. Even if I took action myself, it would be nothing more than that."

The first half of the sentence was quite pleasant to Bai Yixuan's ears, but the second half was off the mark. He couldn't help but say: "Next time you come."

Si Xueyi blinked and said with a smile: "I'm really good at alchemy, but I'm used to using alchemy cauldrons and rarely use alchemy furnaces, so I don't have much chance to do it."

"Just blow it."

Bai Yixuan said expressionlessly.

clang!

At this moment, a rich bell rang throughout Canglan Academy, even in the underground alchemy room.

The bell echoed and the alchemy room trembled slightly.

Bai Yixuan stopped talking and looked at Si Xueyi with some confusion. Si Xueyi said: "This is the Xuanyin Bell. If it only rings once, it's no big deal."

Boom! Boom! Boom!

Before Si Xueyi finished speaking, the Xuanyin Bell rang four more times, and the bells echoed in the alchemy room.

After waiting for a while, the bell finally stopped.

"It rang five times, what does it mean?" Bai Yixuan asked curiously.
