Xia Yu was used to wearing the spirit armor when he came to the principal, and he met some students pointing at him on the way to come just now.

"What the hell is wrong?" Xia Yu asked the old man who drew his blood.

But because of the identity of Xia Yu's watchman, the old man still said: "The key ingredient in your blood, Roche antibody, eh, this name is named after the surname, and the substitute we have made is acidic, and when it encounters the outer layer of the same acidic venom, the two will not only not dissolve, but will provoke each other! After the several demon beasts we used for experiments were injected with venom and antibodies, they would immediately go berserk and could only be executed on the spot......

"Wouldn't it be okay to make the Roche antibody alkaline?"

"Several drugs in Roche antibodies are key ingredients that we can't replace after countless tests, changing any one of them will change the overall efficacy, we have tried countless times......!"

"One leaf vine, have you tried it? Add the sap of one leaf vine to the prepared antibody! Remember to heat the sap of one leaf vine to 37.3 degrees Celsius before adding it to the antibody!" Xia Yu's mouth said automatically.

"One leaf vine?" the old man had never heard of this medicinal herb.

"One-leaf vine, it is a parasitic vine, it is said that if the environment is difficult, it can survive with only one leaf, hence the name one-leaf vine!"

"Is he talking about Yi Wan Lu, which can live on any plant, and the leaves are very sparse......," said an old man, puzzled.

The image of a plant suddenly appeared in Xia Yu's mind, its main trunk was sinking, the leaves were sparse, and the stems were purple-brown with black pockmarks on them.

"Yi Wanlu, possibly, do you have any formed plants now? Show me ......."

An old professor ran to get a Yiwanlu, Xia Yu looked at it a few times, smelled the smell, "That's it, refine it into juice as a whole, and then heat it to the temperature I just said, add it to the antibody, and let it stand for a while, it should be able to ablate the acidity of the antibody without affecting the efficacy of the antibody!"

"Neutral drugs, we envision making antibodies alkaline ......"

"The acid-base reaction will make the drug work extremely fast, but it will also make the user have extremely strong side effects, with the current physical condition of these poisoned people, neutral mild drugs are more suitable......"

"Yi Wanlu, oh, is the one-leaf vine you said really so magical?It basically has no medicinal properties, the juice is dry and bitter, is it really as magical as you say?" An old man stared at Xia Yu, and the implication was to say, boy, you won't be playing with us, right?

"You haven't tried it, how do you know it's useless?

"Headmaster, look ......"

"What are you still doing in a daze, hurry up and do what he says!" The principal yelled, and a group of white coats quickly withdrew, leaving Xia Yu stunned to look at the fast old men, and suddenly found that there was something shaking on his arm, looked down, and couldn't help shouting: "Hey, come back, I still have a needle in my arm......

The principal grabbed Xia Yu's arm, pulled off the needle and still put it aside, and asked excitedly, "Ah Yu, have you finally absorbed the Dragon Codex?"

Xia Yu's unexpected performance just now really made the principal excited, and Xia Yu was now full of money......

"Why don't I come to you...... You also saw it just now, I can't control that situation at all, you can quickly find a way for me to solve it......"

"I can't control it, I can't control it......" The principal smiled very treacherously, took out a pair of bad underwear from the desk drawer, and asked Xia Yu: "Ah Yu, look at this underwear, can you see that there is something wrong with my body?"

"Headmaster, I don't need Longdian to know, you peed your pants......"

"Bastard boy, give me death!" The principal threw his underwear at Xia Yu, Xia Yu hurriedly dodged and avoided it, "Principal, hurry up and think of a way for me, otherwise how can I go to class......"

"It's easy to do, but my idea, you have to suffer a little, can you eat it?" the principal had not recovered from the anger just now, and said to Xia Yu coldly.

"As long as I can go to class, anything!" Xia Yu didn't care much, he was now almost schizophrenic by this nonsense mouth.

"Then you are ready to ......" the principal said, quickly tapping at Xia Yu's throat, Xia Yu felt as if something was stuffed in his throat, only to see the principal laugh happily and said to Xia Yu, "Okay, my silence technique has been successfully performed, your vocal cords can't vibrate, and there is no way to speak......"

Damn, revenge for personal gain, personal vendetta for communiqué! Xia Yu opened his mouth wide, only to see his lips moving, and he really couldn't make even a little sound!

"Yes, I am a communiqué for personal vendetta, and you have the ability to scold me...... Haha......" The principal smiled heartily.

At this time, the old man who had left the needle on Xia Yu's arm just now ran in excitedly and shouted: "Principal, it's successful, the antibody has been successfully developed, and it has been given to the experimental demon beast, although the effect is slow, but the venom has really been removed......"

"Really?" The headmaster, who was stroking his beard proudly and looking at Xia Yu, stood up excitedly, holding a handful of accidentally ripped off the beard in his hand, "Take me to see ......"

The principal said to Xia Yu, who was protesting with his teeth and claws: "What are you doing here, hurry up and go to class, otherwise I will let the teacher remember your truancy ......"

Xia Yu is used to the principal's crossing the river and demolishing the bridge, turning his face and not recognizing people, although he has solved the problem of gibberish, but he can't speak, and he doesn't know when the principal is in a good mood and will help Xia Yu lift the ban.

Not seeing Xue Ya in the principal's office made Xia Yu feel as if something was missing.

When they arrived in the classroom, Xiao Rou and Liu Xinyue were already sitting in their seats. Liu Xinyue was excitedly saying something to Xiao Rou, and Xiao Rou kept looking towards the door of the classroom, and after seeing Xia Yu, her face suddenly appeared happy.

"Idiot, I can't see that you were really bold yesterday! You dare to speak to Ah Xiu like that, since Ah Xiu cultivated the Dragon Yin Drunken World Technique, I have never seen anyone dare to yell at Ah Xiu in person, even the principal didn't dare, you are the first!"

"Yes, Boss Xia Yu, you are too fierce, you are my idol of Angulie! Do you know that yesterday Ah Xiu got drunk for the first time, and scolded you for breaking your body into thousands of pieces......

As soon as Xia Yu sat down, Liu Xinyue and An Gulie surrounded him and said.

It's just that the expressions of the two are different, Liu Xinyue is gloating, and Angulie is truly admired.

"Ah Yu, are you okay?I brought you breakfast, you can eat it quickly......

Xia Yu didn't have time to pay attention to Liu Xinyue and An Gulie, picked up breakfast and ate it.

The breakfast was of a very high level, the bread made of fine plateau wheat and the fragrant original milk made Xia Yu addicted.

"It was so refreshing to see Ah Xiu drunk last night, but I didn't expect Ah Xiu to be so bold after getting drunk that he actually danced a strip......tease in public," Lilia said in a stammered manner.

When Xia Yu heard this, he couldn't help but imagine the scene of Long Lingxiu dancing a striptease. With Long Lingxiu's temperament, appearance, and figure, dancing a striptease must be very sexy......

Xia Yu finished breakfast, wiped his mouth, and sat upright, looking like he was waiting for class.

"Hey, did you notice that he was weird today?" Liu Xinyue touched her smooth chin and looked at Xia Yu, "Why does he look like a dumb person?"

Xiao Rou also looked at Xia Yu worriedly, "Ah Yu, you won't be stimulated by anything, right?"

Xia Yu quickly wrote a line on the paper, "Please don't talk to me, I'm listening to the class in peace, don't disturb!"

"He won't be scared silly by Ah Xiu with a kitchen knife, right?" Liu Xinyue said suspiciously.

"Xia Yu idol, you are my idol, you won't be so fragile, right? I still expect you to lead us out of Ah Xiu's sea of suffering!"

Ruijamin and Gao Yuanfeng were sleeping on the table according to their usual habits.

Xia Yu quickly wrote another line of words in the notebook, "Liu Xinyue, please don't mess with me......"

"It's over, he's really stupid......" Liu Xinyue sighed.

Xiao Rou pulled Xia Yu and said, "Ah Yu, are you okay?" I'll accompany you to the doctor......

"I'm fine, the principal's voice to me led to the operation, and I can't speak now......"

"Surgery?" Liu Xinyue looked at Xia Yu suspiciously, and suddenly clapped her hands and said, "You can't be caught in the legendary forbidden speech, right?"

"Liu Xinyue, please don't be so smart, okay......"

"Haha, I know! Retribution, yesterday you scolded Ah Xiu without words, and this morning's retribution came, the forbidden words!" Liu Xinyue pointed at Xia Yu's nose, "What a good opportunity!" Xia Yu, you big idiot, big idiot, big idiot, big idiot......"

Xia Yu wrote: "You are an idiot......"

It's a pity that handwriting can't compete with Liu Xinyue's speed of speech at all, usually Liu Xinyue spit out more than a dozen times like a cannon, and Xia Yu can only complete a handwriting ......

Xia Yu finally realized the pain of not being able to speak, and the pen is not as good as the mouth......

For a whole day, Xia Yu didn't speak, he could only watch people shouting happily and happily, while he could only settle accounts on the counter in obscurity.

The boss forgave Xia Yu for his temporary aphasia, and even after he knew Long Lingxiu's true identity from Xiaorou's mouth, he waved his hands quickly, because he was a fan of Long Lingxiu......

Still, the boss has a bit of humanity. Of course, it doesn't mean that the boss specially arranged for Xia Yu, who couldn't speak, to settle accounts at the counter, Xia Yu knew that the boss did this because he was afraid that he would snub the guests and affect his income.

The brilliance of the boss's humanity is reflected in another way, which is to chat with Xia Yu.

Of course, Xia Yu couldn't speak, and because of this, Xia Yu felt the cruelty of the boss.

The owner started his glorious deeds from the age of one to the time he opened this restaurant.

Xia Yu had to admire the boss's eloquence. When he was finally promoted to the foreman, he said that he relied on unwavering hard work and talent......

"Ah Yu, after listening to my experience, do you feel very deeply? I can see in your eyes that you want to be as successful as me, so I will say what is in your heart on your behalf......"

The boss said as he lifted a kettle, poured hot water into the teapot in front of him, and the turquoise tea leaves tumbled and floated, and quickly sank......

Xia Yu wrote "twenty" on the notebook in front of him, which was the twentieth pot of tea that the boss drank, and the tea was changed seven or eight times during the period......

When a beautiful waiter passed by Xia Yu, she put her plump body on Xia Yu's body, blew hot air into Xia Yu's ears, and whispered: "Ah Yu, when you come to my room at night, if you don't speak, you will acquiesce, and my sister will leave you the door at night......"

The boss is still telling Xia Yu about his "great achievements" and "romantic years", Xia Yu has been drowned by the boss's endless nagging, but he can't escape - because the boss has blocked the only exit from the counter, and there is a kitchen knife stuck in his back......

Not being able to speak is painful, and it is undoubtedly even more painful to endure the boss talking in your ear for an entire afternoon......

When Xia Yu found the principal angrily and asked to unblock the forbidden speech, the principal obviously expected Xia Yu to come, and slowly took out a teapot, Xia Yu couldn't help but vomit when he saw the teapot, and the boss drank tea in front of him all afternoon!

"As long as you help me overcome these medical problems, I will help you lift the gag technique......" the principal said leisurely.

A medical dilemma?

Xia Yu was suspecting that the principal's brain was crushed by the door, and his head was hit by a thick stack of materials......

Feel free to look at it, "congenital cardiac convulsive hypokinetic syndrome", "contact with contagious skin brown spot disease"......

A large number of names that made people dizzy when they saw it instantly made Xia Yu feel the urge to turn around and want to run.

"If you still want to unlock the mute technique, just stay here for me honestly, don't look for it, Xueya, as my personal assistant, has been busy communicating the latest research results on Venom outside for the past few days, and I won't be able to come back for at least ten days......"

The principal saw that Xia Yu's eyes kept searching in the office, and he didn't understand that Xia Yu was trying to find Xue Ya to save him from the dire situation, so he ruthlessly broke Xia Yu's last bit of hope.

"Don't worry, I'm what I say, after you solve these problems, you will definitely be given a lifting of the ban, and there will be a silver reward, pay attention, but cash...... When it is finally published, it will be published under the name of 'Xia Yun', how about it, the conditions are rich enough, right?"

When Xia Yu heard that there was a silver coin reward, his eyes suddenly lit up, and at the same time, he lamented that he had been hit by the old fox of the headmaster again.

There is no way, silver coins are irreplaceable for Xia Yu just like steak is for demons and spirits.

"Since you agree, then obediently read the information here, if you think of a solution, just record it in this notebook, I'll go to sleep first......"
