In the breakfast hall, all the professors and students in the college are eating.

Cowen held the cauldron in his hand preciously, and rushed all the way to Snape, who was eating at the professor's chair.

Kewen's actions caught the attention of all the professors, and they all slowed down their eating and turned their eyes to look at him.

"Good morning, professors!" Kewen noticed the eyes of the professors, so with a big smile, he rushed to Snape after greeting.

Across the dining table, Kewen's eyes were fiery, and he looked at Snape with a stunned expression.

Then, in Snape's awkwardly stiff posture, Kewan handed over the cauldron in his hands.

"Professor! Look at this!" Kewen put the crucible on the dining table, his voice full of excitement: "I finally succeeded!"

"You...you go away!" Snape reprimanded in a low voice with a stern face.

This big crowd, you Gryffindor, sticky here with me in front of all my Slytherin students, what do you think of me as Snape, I don't think I'm giving you enough points many!

With such an activity in his heart, Snape couldn't help but scolded his face full of lawsuits, and continued to reprimand in a low voice: "What's the matter, go to the office after class this afternoon!"

"Hehehe..." Dumbledore next to him chuckled, raised his head slightly, looked at the cauldron through the lens on the bridge of his nose, and said lightly, "What does it matter, Severus, listen to us What did Xiao Kewen say?"

Seeing this, Professor Flitwick and Professor McGonagall also began to echo with a smile.

"Hehe..." Cowen gave Snape a "what can you do" smirk, and under Snape's stare, he quickly took out two more things from his pocket.

What came out was a stir stick and a serving of herbs.

Kewen quickly threw the herbs into the cauldron, and then used his wand to cast a 'clear water like a fountain' spell into the cauldron.

Next, Kewen adjusted on the rotary knob on the outer wall of the crucible.

While adjusting, Kewen explained to the professors who were watching him: "This is an automatic cauldron that I made with 'alchemy'."

Saying that, Kewen picked up the stirring rod next to him and put it into the crucible.

"There is also this automatic stirring rod, which is also an alchemy item." Kewen had already adjusted, then released his hands, and continued to explain in an excited tone: "Professors, please look! Now I want to configure 'white fresh liquid', I only The Alchemy Crucible and Alchemy Rod need to be set up in advance, and then they can automatically concoct potions!"

The other professors didn't know much about what Cowan was explaining, but both Dumbledore and the four branch deans knew that Cowan had been working on it for a long time.

Therefore, after listening to it, Professor McGonagall immediately interrupted and said with a slight surprise: "You succeeded? Kewen, can you be sure that the potion can be made automatically?"

"It's not a complete success." Kewen shook his head: "There is one more crucial part."

"What part?" Professor Flitwick also asked enthusiastically.

Before Kewen could answer, Snape said with a cold face, staring at the auto-running cauldron, "It's a drug test."

"Yes, it's a drug test!" Kewen repeated, and then again popularized his idea of ​​a 'perfect potion assembly line' to the professors.

Because such a long time has passed, Kewen has supplemented the idea of ​​the 'perfect potion assembly line' several times, and the theory has become more complete.

After listening to Kewen's exposition, all the professors have come to the spirit now. Even the principal and the four sub-deans, who have known for a long time, have no choice but to be tempted after hearing Kewen's more perfect theory.

"So..." Dumbledore asked in a serious tone: "So what do you think about the last part of the 'drug test'?"

"Of course!" Kewen nodded: "Professor Snape's intuition about the medicinal properties of herbs is very accurate! If Professor Snape cooperates, I will be able to successfully produce related alchemy products!"

Speaking of which, Kewen paused, then turned to look at Professor Sprout, and said a little excitedly: "Of course I also teach you! Your knowledge of herbal medicine will definitely be of great help!"

"Since Xiao Kewen asked for help..." Professor Sprout smiled kindly: "Of course I have no problem here."

"Thank you!" Cowan thanked happily, then turned his head back, staring at Snape gleamingly.

Snape was stubborn, but refused to open his mouth to respond.

Seeing this, Dumbledore said with a smile: "I fully agree with Little Kewen's idea."

Saying that, Dumbledore gave the other professors a playful wink.

When the professors saw this, they all laughed and said that they agreed with Kewen's idea while persuading Snape.

"Okay!" Snape finally couldn't bear it any longer, and stared at Cowen rather depressedly and said, "I agree!"

"Thank you Professor!" Kewen waved his fist slightly in joy.

"Speaking of which..." Dumbledore saw that the 'accomplice effect' was achieved, so he said to Kewen: "Listen to your argument, does the potion test items require more advanced alchemy knowledge?"

"It's such a Mr. Principal." Kewen admitted and said confidently: "As long as you give me enough time, I am confident that I can make it!"

"Very good belief." Dumbledore nodded with satisfaction, and continued: "But since some students have asked the Academy for help, the Academy will certainly help them, so..."

Dumbledore lowered his voice and said softly: "I have an old friend who is very accomplished in alchemy.

Perhaps, I can introduce you to him.

You can try to start with a pen pal. If you have any questions about alchemy, you may wish to ask him more. "

When the professors heard this, they couldn't help but feel very surprised. Only a few professors were not so close to Dumbledore, so they were a little confused about the friend Dumbledore said.

"Thank you very much again! Mr. Principal!" Kewen didn't expect this surprise, so he immediately thanked him happily.

At this moment, the alchemy cauldron suddenly made a pleasant sound of 'ding'.

Kewen immediately stretched out his hands and began to cool the medicinal liquid, while explaining: "This is a reminder device I designed to remind me that the potion has been refined."

Saying that, Kewen poured the cooled potion into a small crystal bottle, and then handed it directly to Professor Snape.

Snape stared at Cowen, then raised his hand to take the potion and started testing...
