"What's the matter?" Ye Xuan asked.

Gu Liang smiled and said, "The prefect of Qingyuan City needs to refine a level 4 pill. However, there are two medicinal materials that we cannot melt. So, I want to ask Master Ye, you... I don't know if Master Ye can melt it."

"Prefect?" Ye Xuan nodded slightly. The so-called Prefect is the first person arranged by Qianyun Kingdom to guard Qingyuan City, or the city lord.

It can be said that the entire Qingyuan City and even the entire Qingyuan County are under his control.

He is Zhang Lu!

Although Ye Xuan in his previous life had very few opportunities to come into contact with top figures like Qingyuan County, he knew Zhang Lu's name.

"What two kinds of medicinal materials?" Ye Xuan asked again.

"Tianxin vine, silver frost fruit." Gu Liang said.

Ye Xuan raised his eyebrows: "Tianxin Vine and Yin Frost Fruit? These two medicinal materials are level 5 medicinal materials, and are they used to refine level 4 elixirs. Isn't it too wasteful?"

Gu Liang looked at Ye Xuan in surprise, and Changsun Feiyan beside him was also a little surprised.

With Ye Xuan's elixir skills, don't you really know this simple truth?

However, Gu Liang still explained: "Well, Master Ye... In theory, level 5 medicinal materials can be used to refine level 5 pills. But in fact, when it comes to level 4 or above, it is very difficult to refine level 4 or above, so... usually, it is necessary to use higher-level medicinal materials to refine level 4 or above."

"In other words, refining level four pills requires level five medicinal materials, while refining level five pills requires level six medicinal materials?" Ye Xuan shrugged.

"That's right!" Gu Liang nodded.

After hearing Gu Liang said this, Ye Xuan understood.

No wonder Guliang and Changsun Feiyan both looked at him with surprise.

It turns out that in their understanding, if we actually need level 5 medicinal materials to refine level 4 pills?

But for Ye Xuan, this is not the case at all.

The top alchemy masters among the immortal cultivators can refine even an ordinary weed plant into a spiritual pill, and can even refine advanced pills with third-level medicinal materials.

Even Ye Xuan did not focus on the method of alchemy, but he could use lower-level medicinal materials to refine higher-level elixirs.

"I wonder if Master Ye can melt the Tianxin Vine and Silver Frost Fruit?" Gu Liang asked again.

"Yes!" Ye Xuan nodded.

In fact, if it were yesterday, Ye Xuan could not melt these two medicinal materials.

But today, he has practiced to the third level of Qi training and can initially control some of the true qi to leave the body...

If he was asked to melt the amethyst grass and the syringae, there would be no need for two alchemy furnaces, nor would he need to hold the alchemy furnace to rotate. He just needs to use the true qi to control the two medicine fluids to continuously rotate rapidly during the process of melting the medicine fluid.

As for Tianxin Vine and Yinfrost Fruit, these two medicinal materials are not mutually exclusive.

However, the vine juice after the melting of Tianxin Vines is extremely easy to solidify when it encounters the cold power of the silver frost fruit, and turns into ice residue. The medicinal effect will be directly frozen. Even if it is melted at high temperature, it will lose its medicinal effect.

As for why we don’t use high temperatures to catalyze the fusion of silver frost fruit and Tianxin Vine, it is because silver frost fruit cannot withstand high temperatures. Only after it is fused with Tianxin Vine can it be melted again at high temperatures.

This is the biggest reason why Tianxin Vine and Silver Frost Fruit are difficult to blend.

"That's great!" Gu Liang showed joy. In fact, when he asked Ye Xuan, he didn't really think that Ye Xuan could combine these two medicinal materials.

At this moment, he was naturally quite happy to receive Ye Xuan's affirmative answer.

Because of this problem, he has been bothering him for a while.

"Then... Master Ye, you go and choose a suitable alchemy furnace first." Then, Gu Liang asked someone to take Ye Xuan to choose an alchemy furnace.

When Ye Xuan just left Guliang's room, he heard Changsun Feiyan say, "Master, is Ye Xuan's attitude towards you a bit too casual? If you intend to accept him as a closed disciple, it would be fine if he refuses, but he doesn't even think of you as a senior at all."

Gu Liang said, "It's okay, Feiyan. Ye Xuan is a person with real skills. He is so young that he has unique attainments in the art of alchemy. It is inevitable that he is a little arrogant..."

Ye Xuan curled a faint smile at the corner of his mouth, and then walked away.

Although Zhang Changsun Feiyan was also very polite to Ye Xuan, the one who actually invited Ye Xuan to Yuanling Pill Pavilion to serve as an alchemist should be Gu Liang.

Changsun Feiyan just followed Gu Liang's words and told Xinghe Martial Arts Academy to invite Ye Xuan.

Ye Xuan followed a maid from Yuanling Dan Pavilion to the secret room where the alchemy furnace was stored.

"Master Ye Dan. This is the Dan Furnace Warehouse. Go in and choose, I'll wait for you here!" The maid said respectfully, and the look at Ye Xuan had a hint of admiration.

In Yuanling Dan Pavilion, most people already know Ye Xuan's identity, and most of them admire this young alchemist, especially these maids, who are mostly young girls. They often have no talent in martial arts, so they start to make a living early.

For these girls, in their eyes, alchemists are noble figures.

Moreover, Ye Xuan is so young, even younger than them, so naturally he will inevitably make some maids feel affectionate.

Ye Xuan responded and then walked into the warehouse where the alchemy furnace was stored.

For a real alchemist, a handy alchemy furnace is naturally very important.

However, Ye Xuan did not think that he could choose a elixir furnace suitable for him here.

After all, the level of alchemy cultivation by martial artists is too poor, and I think the alchemy furnace will not be much better.

Just as Ye Xuan was planning to choose a decent elixir furnace, his eyes suddenly flashed and landed on a black elixir furnace in the corner.

Ye Xuan walked over and picked up the black pill furnace.

Judging from the appearance, this black alchemy furnace is half smaller than an ordinary alchemy furnace.

However, Ye Xuan knew that the alchemy furnace that truly portrayed the magic array was enough for such a large size.

Most of the alchemy furnaces in Yuanling Dan Pavilion look much larger because there are very few alchemy furnaces that really have formations, and most of them are shallow array patterns. These array patterns do not form magic circles.

And the alchemy furnace in Ye Xuan's hand at this moment definitely portrayed the magic array.

"My cultivation level has not yet recovered by one or two, so I can't see the level of this alchemy furnace. But this alchemy furnace is definitely much better than most alchemy furnaces!"

Ye Xuan blew away the dust covered on the elixir furnace, then scanned the elixir warehouse before leaving.

"Master Ye, have you selected the alchemy furnace?"

When Ye Xuan met Gu Liang in the first floor hall of Yuanling Pill Pavilion, Gu Liang looked at the alchemy furnace in Ye Xuan's hand in surprise.

"Yes, that's it!" Ye Xuan nodded.

Gu Liang smiled slightly and asked again: "Master Ye. You don't think there is a formation on this alchemy furnace, so you chose this alchemy furnace?"

Ye Xuan frowned slightly. Gu Liang also knew that there was a magic array on this alchemy furnace?

Seeing Ye Xuan's expression, Gu Liang knew that he was right and smiled:

"Actually, several alchemists from Yuanling Dan Pavilion used to be interested in this alchemy furnace, but later they tried it several times, but they failed to refine the alchemy, and the magic array on it seemed to be destroyed. Therefore, they all gave up this alchemy furnace."

"Oh?" Ye Xuan's eyes showed surprise. It seemed that besides him, other formation masters also saw the tricks.

But... the formation on this alchemy furnace was really destroyed?

Ye Xuan does not have spiritual consciousness now, otherwise his spiritual consciousness could be seen directly with a scan.

The only way now is to test it through true qi.

But in this case, it is obviously not suitable to do so.

"It doesn't matter. I plan to buy it and study it carefully!" Ye Xuan said.

"What are you buying? This elixir furnace has been kept in the warehouse for several years. If you want it, just take it. But... Master Ye, try not to use it to refine precious elixirs." Gu Liang said with a smile.

"I understand!" Ye Xuan nodded.

"Since that's the case, let's go to the prefect's mansion now. The prefect should have been waiting for us in the mansion for a long time..." Gu Liang said again.

Then, Ye Xuan, Gu Liang and Changsun Feiyan each took a carriage and rushed towards the prefect's mansion.

Soon after, the carriage stopped.

The prefect's mansion is located in the center of Qingyuan City, covering an area of ​​more than 100 acres, with red lacquered gates and towering white walls.

The pavilions, towers, corridors and eaves in the courtyard are mangrove, and the above-mentioned sandalwood and yellow rosewood are beams, covered with the most exquisite glazed tiles and jade tiles.

It's really a luxurious mansion.

A guard from the prefect's mansion led Gu Liang in, while Ye Xuan and Changsun Feiyan followed him.

A group of people walked past the courtyard covered with rockery and waterfalls.

During this period, Changsun Feiyan looked at Ye Xuan intentionally or unintentionally.

She thought Ye Xuan would be shocked by the grand scene of the prefect's mansion.

However, Ye Xuan was walking leisurely in the garden, calm and composed, as if walking in such a luxurious prefect's mansion, just like walking on the street.

In fact, Ye Xuan has long been accustomed to luxury mansions.

No matter how luxurious the prefect's mansion is, how can it be compared with the mansions of the earth immortals and the robbery immortals in the Ziwei Star Realm?

I'm afraid that the pearl inlaid in the mansions of those robbery immortals can be exchanged for many such mansions.

Soon, Ye Xuan and his friends came to a relatively secluded side courtyard.

However, at this time, more than a dozen people gathered in this side courtyard.

"Master Gu, I finally waited for you!"

A middle-aged man wearing a golden robe, long eyebrows and starry eyes, and square face walked over.
