The elixir has been collected, and it is ready to start alchemy.

Although the elixir could only play a suppressive role, no matter what, Wu Feng still hoped to relieve the pain of his mentor, even if these elixirs were priceless, he did not frown at all.

When he came to the ward again, in addition to the dean's presence, unexpectedly, there was a mysterious black-robed old man.

However, he had a relationship with this old man.

At the beginning, at the princess's banquet, she protected herself from being bullied by the enemy country, and Lingzong's strength was fully revealed, but she always had a cold old face, as if everyone wanted to punch her, especially when she looked at herself......

"You are Wu Feng?"

When the black-robed old man saw him come in, he squinted, looked up and down, and asked lightly.

Wu Feng blinked, didn't understand what the situation was, and didn't dare to talk nonsense, and looked at the dean for help.

He was slightly wary in his heart, this old man wouldn't want to beat me, why do I think he was a little unfriendly to me.......

The dean coughed: "Xiao Feng, you are back, the princess should not embarrass you, that, let me introduce you, this is our Longwu Empire, one of the four great princes, Du Tiesheng, Du Lao! Xiao Feng, you have to call Uncle Shi ......"

"Hello Uncle Shi!" Wu Feng shouted obediently, but he was a little worried in his heart.

Because, he felt that this uncle's eyes seemed to be able to penetrate people, and he couldn't see from the inside out, and he didn't know what he was looking at.......

Du Tiesheng snorted coldly: "I am the second oldest among the senior brothers, you are my senior brother's disciple, it stands to reason that I should not embarrass you just after we met, but ......"

But what?

Wu Feng scratched his head, he really couldn't remember when he had provoked this senior uncle.

Du Tiesheng squinted his eyes and said with hatred: "Stinky boy, since my family Bai Li went back, he didn't think about tea and food all day long, what did he say that he met a genius through the ages, he practiced for a year, and he couldn't stand up to others for a day, and now he is simply disheartened, and she doesn't have the usual hard work, if she goes on like this, she will sooner or later be reduced to mediocrity, you say, how can we calculate this account? That's my genius baby disciple, I can't meet one for many years!"

"Haha, senior brother is angry, Xiao Feng didn't mean to ......"

Bai Xuan saw that he was not angry, so he hurriedly stepped forward and patted his back lightly for him.

Wu Feng raised his head in confusion, and his head was a little unable to turn.

No, what does what you are talking about has to do with me......

At this time, Qin Wan suddenly broke in and asked angrily, "Wu Feng, how is it, has the pill been refined?"

Bai Xuan was stunned, and hurriedly played the round: "Yes, yes, yes, let's refine the pill first, Xiao Feng can't run anyway, senior brother, you will be training later, Tutor Caiyun is still in urgent need of medicine!"

Du Tiesheng rolled his eyes and snorted coldly: "And you, I haven't said anything about you yet, I can send the apprentice back to save my relatives with confidence, you are good, I don't care at all, that's also your own granddaughter, how can this grandfather be, seventy or eighty, and he is so heartless!"

"Yes, yes, what my brother taught me!"

Bai Xuan smiled bitterly and hurriedly agreed, if you don't make this service comfortable, I'm afraid you won't want to refine this Dan today.

Although, Caiyun has a jade talisman to suppress it, and he is not in a hurry, but it can be reduced by one point, and it all depends on Xiao Feng.....

Du Tiesheng snorted twice, his face suddenly turned, he leaned into his ear, and whispered: "Hey, junior brother, what I just said, don't tell senior brother, if you know that I reprimanded his disciple like this, you will definitely pick my skin ......when you come back."

Bai Xuan: ".........."

........

Wu Feng breathed a sigh of relief, took out the Dan furnace from the space ring, set up the medicinal materials, and prepared to start alchemy.

Qin Wan was also busy beside her, serving tea and pouring water, and serving her in a good manner.

Looking at Wu Feng's serious expression, Du Tiesheng sneered and said, "I thought it was a genius, I didn't have any common sense at all, just like you, how did you refine the sixth-order elixir at the beginning......?

Wu Feng was stunned: "Could it be that Uncle Shi still understands alchemy?"

"Although I don't understand alchemy, I know the basic common sense, boy, from the beginning to the present, you have made a total of three mistakes, do you know what they are?" Du Tiesheng took a sip of tea and smiled proudly.

Wu Feng hurriedly asked modestly: "Please also ask Uncle Shi for advice!"

"Well, this is easy to say, for the sake of you calling me uncle, I will tell you, first, if you want to refine the seventh-order elixir, the Dan furnace must use a purple Xuan furnace made of purple gold and dark iron, and your broken copper furnace can't effectively gather spiritual power at all, this mistake has already reduced your chances of becoming a pill by seven percent......"

Du Tiesheng shook his head proudly, he was able to reprimand Senior Brother, a disciple of the alchemy family, and this satisfaction was so refreshing.

Hmph, let you always bully me, after studying art by Master's side for 30 years, you let me wash my socks for 29 years, this hatred, I have never forgotten......

Wu Feng saw that he suddenly stopped talking, and hurriedly asked, "What about the second one, uncle?"

Du Tiesheng coughed twice, and did not answer directly, but pretended to say: "Hey, my tea is gone, tsk, what should I do......"

Wu Feng was stunned for a moment, and continued to pour the tea when he ran out, the teapot was next to you, what a strange old man......

Seeing that he didn't react, Du Tie snorted angrily: "Come here, pour a cup of tea for Uncle Shi, I don't have any eyesight, if this is my apprentice, I would have been killed by me!"

Bai Xuan couldn't stop smiling bitterly beside him, Xiao Feng fell into the hands of my senior brother, it was not good.

"Oh, you said it earlier....." Wu Feng hurriedly came over and handed over a cup of tea, waiting for his guidance.

After drinking the tea, Du Tiesheng nodded with satisfaction and continued: "Well, this second point is the problem of the elixir, refining the seventh-order elixir, the elixir must be pure and free of impurities, but no matter which elixir is more or less imperfect, what should I do at this time?"

"What should I do?" Wu Feng asked.

"Stupid, of course I quenched the elixir into liquid in advance, alas, how did my senior brother teach you......"

Du Tiesheng shook his head helplessly, it's really rotten wood that can't be carved.....

"Uncle Shi, hurry up and say the third one!" Wu Feng asked impatiently.

"The third?"

Du Tiesheng glanced him up and down, and snorted: "You kid, are you really stupid or fake, can you refine the seventh-order elixir, you are only in the early stage of a spiritual warrior, is the spiritual power capacity enough? Haven't you thought about these problems? You know, the most basic condition for refining the seventh-order elixir is the cultivation of the spirit master, you, it's still early......

As he spoke, he drank all the tea, and now, Du Tiesheng could be regarded as raising his eyebrows.

Senior brother, senior brother, the two of us are really evil, it's just that you bullied me, and your apprentice actually bullied the door.

Pity my Li'er, forget it, if I hit this kid today, I should charge some interest, and I'll clean him up when I come to the future!

"Boom!"

With a muffled sound, Wu Feng sealed his hands, drew out the spiritual fire, and prepared to start alchemy.

Du Tiesheng was stunned for a moment, and tea squirted out of his mouth: "Hey, hey, what I just said, you are all on the sidelines, haven't you, I have clearly pointed out the three mistakes to you, you have no chance of success in this wave, and you still practice?

Wu Feng blinked: "Uncle Shi, although I agree with what you said, I still have some confidence in myself.....

Hearing this, Du Tiesheng resolutely stretched out his thumb: "Okay!

But the irony in that eye can be seen even by the blind.....
