Master, you go first!

What Lao Xu didn't know was that Gu Jiu told Ji Chuxue that he bought the materials mainly to refine the alchemy furnace for his master. Ji Chuxue agreed very smoothly. Gu Jiu doubted whether the sect leader was a love brain.

However, although Lao Xu disliked Gu Jiu for being a prodigal, he still smiled like a flower when he got the pill furnace.

Finally, Lao Xu chose a dark red pill furnace, which was made of hematite ore. It was characterized by rapid heating and uniform heating.

"Choose a name, Master."

"Is it so troublesome?" Lao Xu said the most indifferent words with the most cheerful expression, "Then let's call him 'Chu Yang'."

"A good name, the rising sun is full of hope." Gu Jiu flattered him.

Xu Yuhong collected the alchemy furnace very happily, and Gu Jiu followed him to the alchemy room in the front hall.

When he came to the alchemy room, Lao Xu carefully checked the medicinal materials required for the fourth-grade and fifth-grade Juyuan Dan, sorted them one by one, and placed them on the table beside him.

Before starting the refining process, Lao Xu also took a portion of the third-grade Juyuan Dan medicinal materials and tried it in the alchemy furnace. The effect was beyond his expectation. As expected, it was easy to refine it with a good alchemy furnace.

Later, Lao Xu began to refine the fourth-grade Yuan Judan. Gu Jiu was studying seriously on the side.

Following Lao Xu's operation, the heat reached a certain level. He waved his hand and put the medicinal materials into the alchemy furnace in an orderly manner to extract the medicinal power. The medicinal power condensed like suspended water vapor and slowly gathered into water droplets in the alchemy furnace. Then different medicinal powers merged together bit by bit, combining into a colorful liquid.

After the extraction and condensation of the medicinal power is completed, the most critical step of making the elixir is reached. It was obvious that Lao Xu controlled the firepower very steadily and kept exerting spiritual power to squeeze.

After half an hour of refining, the first batch of fourth-grade Yuanyuan Dan was successfully produced. There are three pills, which is already a very good effect. You need to know that the higher the grade of pills, the lower the chance of producing multiple pills.

Seeing the elixir being successfully released, Gu Jiu clapped his hands and applauded, as excited as if he had made it himself.

Lao Xu picked up the elixir and felt its power carefully.

"This fourth-grade medicine is already very good. This medicine has a strong fragrance and a good quality. It should not be much worse than the Qibao Yuan-Pui Yuan Dan."

"Master, let's try the fifth-grade one. Maybe it can surpass the Seven Treasures Peiyuan Dan. That wouldn't be better."

Old Xu calmed down, took a short rest, and took a pill to restore his spiritual power. Then he began to try to refine the fifth-grade Yuan Ju Dan.

There were a lot more medicinal materials this time, and it took longer. It took about an hour to extract the power of the condensed medicine.

Finally, when the elixir was being prepared, Gu Jiu was waiting by the fire with great anticipation. As a result, it exploded, and a puff of black smoke came out, blackening his face.

"Cough cough cough."

The master, apprentice and grandson were choked to the point of coughing.

"What's going on? It was obviously going to succeed, but it exploded." Gu Jiu muttered.

Lao Xu carefully thought about the process just now, and the steps were correct. After thinking about it for a long time, I still haven't figured out which link caused the problem.

Unable to figure it out, Lao Xu decided to try again. This time he must pay more attention. Even if he failed, he would try to find the reason.

Gu Jiu nodded in agreement. This time he sat far away.

Repeated the last steps, and finally repeated the last failure. Still can't successfully achieve elixir.

This time Lao Xu felt that it was going well, but why did he always explode at the last step of forming the pill. Lao Xu was very distressed, and so was Gu Jiu.

Lao Xu thought for a long time and didn't understand.

"Master, what do you think? Is there something wrong?"

"I don't know. It's been going smoothly all the time. It's the last step. I practiced it according to the methods recorded in ancient books. There were no mistakes. It's strange."

"Ancient books, um..." Gu Jiu started to use his smart brain to work quickly.

After a while, the light bulb came on in my head,

"Master, does the final elixir need to absorb spiritual energy?"

"It's necessary. It's normal for this type of elixir to absorb spiritual energy."

"That's it. It must be that the spiritual energy is not enough to support the elixir. This elixir is from the Great Immortal Cultivation Era. The aura environment at that time was excellent, which is different from ours now. If this is the case, I suggest you go to Try it in the spirit gathering array, it might work."

"It makes sense. Let's go and give it a try." Xu Yuhong suddenly nodded and said.

When they arrived at the Back Mountain Waterfall, Shen Nian was kicked out of the Spirit Gathering Array and sat outside the Spirit Gathering Array with Gu Jiu watching Lao Xu refining elixirs.

"Gujiu, why do you come here to make alchemy instead of going to the alchemy room?"

"Well, I just thought that we might not have enough spiritual energy. We have already failed two furnaces, so we came here to give it a try."

"Oh, that's how it is."

"Yes, that's it. What's wrong? Are you unhappy because it disturbs your practice?"

"That's not true. Hehe, it's about combining work and rest, as you said. Let's go and read poetry."

"..." Gu Jiu didn't expect that since this girl was introduced to poetry before, she would no longer be addicted to story books, but become obsessed with poetry.

So Gu Jiu took some time and went to the study room with Shen Nian for a while. The small villa is very close to here, just a few steps away. Gu Jiu calculated the time for about an hour, then ran out to see Lao Xu's results.

The result was exactly as Gu Jiu said. After the aura environment changed, Lao Xu successfully completed the last step of forming the elixir.

Two per batch. When the elixir was formed, a strange phenomenon also appeared nearby, but it was not very exaggerated. A small vortex appeared in the sky above his head. It shouldn't alarm anyone nearby.

Seeing that Lao Xu succeeded, Gu Jiu flew over happily. Watching Lao Xu take out two elixirs with a colorful shimmer from the elixir furnace.

Gu Jiu couldn't help but say,

"Hahahahaha, I am indeed very witty."

"Haha, you really got it right. It was caused by insufficient spiritual energy."

"Master is so powerful. He has refined fifth-grade Yuan Ju Dan. Do you have this elixir of heaven level?"

"Well, it should be the lowest level of heaven. You can try to give them two breakthroughs. The best you can achieve."

"Let's go and give them the elixirs. Haha, the sect has added two more Nascent Soul masters. Just think about it, I'm impressed." Gu Jiu couldn't wait to see the two peak masters break through.

Xu Yuhong put away the elixirs, and the three Danfeng treasures set off together to deliver the elixirs to Lu Qian and Lin Miaoxun.

Menghululu Qian's eyes lit up when he saw this fifth-grade Juyuan Dan. I ran into the spirit gathering formation and started trying to break through. The result was very smooth and the bottleneck was quickly overcome.

Lu Qian's breakthrough was ordinary, and Gu Jiu thought it would cause some strange phenomena from heaven and earth. Unexpectedly, the movement was not as big as when he broke through the foundation building. Well, it was very sloppy.

After the breakthrough, Lu Qianchai cried with joy. He was so excited that he swung his sword and made a "fearless sword". As a result, he shaved his head flat on a hilltop not far from Jianfeng.
