Xu Gongzi....

Faced with this unfamiliar title, Wei Yuan and the others instinctively searched in Si Tianjian's internal list, among the five existing disciples of the prison.

No, this white-clothed person is talking about "Gongzi Xu" instead of "Senior Brother Xu", and the person who opened the lecture was not a disciple of Si Tianjian, but an outsider.

Surname Xu.... Could it be.... The eldest princess's eyes flickered, and she had a bold guess in her heart, and she couldn't wait to verify it.

At the same time, Wei Yuan's eyes showed a sudden look, and he also had a certain guess.

Song Qing once told him that Xu Qi'an was an amazing alchemy wizard, but Wei Yuan didn't pay much attention to it at the time, after all, Song Qing was the first person in Si Tianjian to supervise alchemy.

The genius in his mouth may only have an excellent alchemy talent, and he is categorically unable to compare with the first person in alchemy, and is even called "my master".

Wei Yuan glanced at the two righteous sons, and their faces and eyes had the same confusion and confusion. Obviously, Xu Gongzi and Xu Qi'an were not linked, and the two of them forgot what Song Qing said that day.

"Father-in-law, when did Si Tianjian come up with a surname Xu?" Nangong Qianrou was in charge of intelligence and torture, and was extremely sensitive to this kind of sudden appearance.

Yang Yan, who didn't like to speak, tilted his head slightly and looked at Wei Yuan with a verifying look.

Although the two golden gongs forgot Song Qing's evaluation of Xu Qi'an that day, they still remembered Jiang Luzhong's words the day before yesterday.

Wei Yuan smiled: "You can see it when you go upstairs." ”

The eldest princess has already lifted her skirt and climbed the stairs gracefully, she is tall and tall, with excellent proportions, and her back alone gives people infinite beauty.

You don't need to look at the face to know that she is a peerless beauty.

....

"The essence of alchemy is equivalent exchange. ”

The clever white-clothed warlocks answered his question in Xu Qi'an's words.

"Extract the essence from things, and turn waste into treasure. There are also alchemists who give answers based on their own experience.

The warlocks below the sixth rank did not answer, and listened attentively, and the alchemists of the sixth rank spoke one after another, giving their own confessions.

Most of them are one-sided, and the answers are given based on their own experience.... As for the guy who paraphrases my famous quote, he only knows one thing and doesn't know the other.... Si Tianjian's theoretical knowledge is indeed lacking.

Xu Qi'an listened patiently, neither agreeing nor objecting.

After the white clothes finished publishing, they all looked at Song Qing.

Song Qing is the personal disciple of Jian Zheng, and he is also recognized by Si Tianjian as the first person in alchemy, he is immersed in the field of alchemy and refuses to be promoted, only fascinated by alchemy, and disdainful of the high-grade realm.

The other fourth- and fifth-grade senior brothers were inferior to him in the field of alchemy.

Song Qing shook his head and sighed.

.... What does Senior Brother Song mean by this? When the white-clothed warlocks were puzzled, they heard Xu Qi'an clapping his palms.

Everyone immediately turned their attention to this alchemy wizard.

Xu Qi'an met everyone's gaze and sighed: "In the entire Si Tianjian, in the field of alchemy, only Senior Brother Song makes me admire and is regarded as a master who can be compared. ”

The white-clothed men of Si Tianjian were in awe.

Song Qing smiled slightly and quietly straightened his waist.

Xu Qi'an continued: "Senior Brother Song's meaning is actually to say that what everyone here said is right, but it is not comprehensive, so it is not right. ”

Everyone looked thoughtful.

Xu Qi'an said eloquently: "Alchemy is a very broad field, and everyone here may understand it a little bit in their hearts, but they are all relatively vague and general.... Well, originally, I only promised Senior Brother Song Qing to teach you a piece of knowledge, but Senior Brother Song Qing insisted that I pay back the original with interest, so I will talk a little more, be a little more broad, and be a little more thorough. ”

As soon as he finished saying this, the eyes of the white-clothed warlocks instantly became hot.

"Senior Brother Xie Song, Master Xie Xu. ”

"Xu Gongzi, let's start quickly, I can't wait. ”

The noise suddenly became noisy, and it reached the ears of the eldest princess who had ascended to the seventh floor, and she paused, and did not go in immediately, but looked at the young man who stood in front of the desk, pointing out the passionate words to the always arrogant warlocks.

Xu Qi'an, it's really him!

Wei Yuan paused synchronously, and after seeing Xu Qi'an, his expression paused, and he resumed like this.

At the same time that Wei Yuan stopped, Nangong Qianrou, who had a feminine temperament, and Yang Yan, who was paralyzed, also crossed the shoulders of the eldest princess and Wei Yuan, and vaguely saw Xu Qi'an.

It turns out that what Jiang Lu said is the truth.... Yang Yan stared at Xu Qi'an for a moment, his chin undetectable.

This gong can only be under his command, and no one wants to grab it.

Nangong Qianrou originally wanted to go in directly to listen and see what the kid could say, but she noticed that the eldest princess and her father-in-law had no intention of disturbing, so she endured it and stayed put.

Xu Qi'an said: "The essence of alchemy is equivalent exchange, this is the criterion of the outline, but it is not imaged, only an alchemy master like Senior Brother Song Qing can understand the true meaning of this sentence.

"When it comes to alchemy, laymen subconsciously think of elixir and potions. If you understand a little bit, what comes to mind must be this..."Xu Qi'an said this, pointing to the simple jewelry between Chu Caiwei's green silk: "Metal!"

The white-clad warlocks bowed slightly.

"I want to tell you that these are just two of the realms of alchemy, which I classify as medicine, and materials. Most alchemists only study in these two fields, and occasionally jump into other fields. But only Senior Brother Song, his eyes are already in another independent field. ”

The white-clothed warlocks suddenly looked at Song Qing, Song Qing was stunned, as if he had found a confidant, and his eyes suddenly became hot.

He knew that Xu Qi'an was going to focus on the field of grafting organisms.

Perhaps, this lecture will also be an important step for him to step into the new field of alchemy.

Thinking of this, Song Qing became short of breath.

Outside, the eldest princess and Wei Yuan couldn't help but look at Song Qing, this wonderful disciple of the prison, the two were no strangers.

Knowing that he was always tinkering with some terrible alchemy, he was even imprisoned for it.

Is Xu Qi'an's alchemy really advanced to this point? Can you guide Song Qing?

"Senior Brother Song Qing's research direction is in the field of biology. Xu Qi'an said: "That's right, alchemy is not only for dead things, living things are also in the field of alchemy. ”

A white-clothed warlock stood up and said in a deep voice, "Master Xu, Master Jian Zheng said that life is not within the scope of the alchemy realm. ”

Although he admired Xu Qi'an's attainments in the field of alchemy, these words went against the admonition of the supervisor and contradicted his philosophy.

The other white-clothed warlocks present were also skeptical and unconvinced.

The eldest princess turned her head and looked at Wei Yuan with an inquiring gaze, who smiled and said softly, "I agree with Jian Zheng's opinion. ”

The eldest princess nodded and looked at Xu Qi'an again.

Let's see what he says.

"That's because Senior Brother Song Qing's method was wrong, so Lord Jian Zheng criticized him. But he wasn't wrong in the right direction. Xu Qi'an said.

Of course, he will not raise the bar with the prisoner, even if he wins the debate, but in case the old man is unhappy and can't coax him, he will slap him to death and find someone to cry with.

When Song Qing heard this, he was very unconvinced, but he did not refute it, and patiently listened to what he said next.

"You might as well recall that we extracted metals from ores, harder metals from metals, and refined elixirs from medicinal herbs. But we can't extract chemicals from metals, we can't extract metals from medicinal herbs. Xu Qi'an sold it: "Why?"

"Medicinal materials are medicinal materials, and ore is ore, Xu Gongzi's question is strange. ”

"Haha, metals can be extracted from medicinal herbs, so can't we extract gold and silver from white rice?"

In the eyes of the white-clothed warlocks, Xu Qi'an's question was like asking: why the sun rises in the east, why people starve to death if they don't eat, and why there are twelve hours in a day.

The white-clothed warlocks exchanged heads, but Song Qing vaguely touched something, and his brain was messed up by the white-clothed juniors, and he couldn't calm down and think.

"Smack!"

Song Qing slapped the table and got up: "Clear!"

After roaring, his face was red, his breath was short, and he stared at Xu Qi'an: "You say, say it quickly!!"

The white-clothed warlocks stopped talking, they rarely saw such a Senior Brother Song, and at the same time, they also realized that what Xu Qi'an said was a truly advanced knowledge of alchemy.

Xu Qi'an looked past the white-clothed people, saw Wei Yuan from afar, and his heart sank.

.... Lying down, when he was pretending to be energetic, he was watched by the leader..... Xu Qi'an instinctively resisted, which is a kind of weakness.

The warlocks of Si Tianjian are like a group of rigorous science otaku, they only pay attention to alchemy itself, and do not care about the origin of alchemy.

Even if they feel suspicious, they will automatically ignore it, and as long as they can learn the profound alchemy, they don't care about anything else.

Wei Yuan is different, Wei Yuan is a politician, military strategist, strategist, and a lot of smart people with a halo on his head.

Smart people tend to think too much.

Xu Qi'an's strategy for the white-clothed warlock is to appear in front of people, and pretending to be exaggerated as much as possible. And the strategy for Wei Yuan is to show loyalty, and to pretend to be harmless within a reasonable range.

The current situation is obviously not a small pretense, but a direct word.

At this time, Wei Yuan bowed slightly towards Xu Qi'an.

"Whew.... Thinking about it from another angle, showing one's own value in front of the leader is also an effective way to win attention and increase bargaining chips!"

Xu Qi'an took a deep breath, got rid of distracting thoughts, and let the focus return to the classroom.
