Xin Sheng had no time to say hello to Natiya, and the three of them stood beside Nagini, watching Snape pour the bottle of vicious potion like fel's blood on Nagini.

What made Snape embarrassed happened. Nagini had no response to the potion, but just turned his snake eyes lazily and looked at Snape.

Snape couldn't hold back on his face, and he returned to the magic cauldron with a gloomy expression, and continued to study the new potion without saying a word.

Xin Sheng knew Snape's personality. Once he showed even a little ridiculous expression on his face, the old bat would definitely hold a grudge.

"Cough~"

Waving his hand, Natiya and Xiri retreated first, Xin Sheng kept his serious expression and placed the ghost mushroom and soul dust moss on Snape's laboratory bench.

"I've found the materials."

"Um."

Snape said in a slight tone, "Agreement is an agreement. Put the ingredients there. I will find time to boil the requiem potion."

Xin Sheng didn't plan to chat with Snape too much. This guy would be crazy and vicious when he was in a bad mood. He didn't want to be the bad guy.

"Chiri, what potion is you spraying on Nagini?"

Xili handed the watering can to Xin Sheng: "This is an advanced Maripo Forest Potion made by reducing the efficacy of the medicine by alternative materials with the help of Professor Snape."

“Maripo Forest…”

Xin Sheng shook the watering can with interest: "I remember the effect of the Maripo Forest is to speed up human adrenaline secretion in a short period of time, right?"

"Why is this medicine effective for Nagini, a snake?"

Snape interrupted in a gloomy tone: "The effect of this potion has given us a definite conclusion."

"The drugs that are effective for humans can also work in Nagini, which shows that even if she becomes a big snake, she still maintains certain human characteristics."

"This particular state is very similar to the wizard who uses the Animagus transform."

Xiri added with a wink and said, "The Blood Curse is also a curse. With this in mind, I tried it with the principle of lifting the curse of the Vampire Bird, but it failed to achieve the effect."

Xin Sheng received Xili's gaze and roughly understood what she meant.

‘Is the difference caused by different rules in the world? Animagus…’

Animagus is a special deformation technique used for himself, which can turn humans into animal forms.

All Animagus have only one animal form, and cannot change at will like Sun Dasheng’s Seventy-Two Changes, and will determine the life of one life.

And Animagus cannot become a magical creature.

Judging from the results of past research by wizards, there should be an essential difference between the body structures of magical creatures and mammals such as humans.

Xin Sheng has not studied deformation techniques much, but Xili is very interested in this aspect and often tries to change the shape of objects at home.

Just as the characteristics of Xiri's wand show, she has a strong talent for transforming techniques and has the intention of in-depth research on this aspect.

"Bang!"

It is so difficult to start researching a new potion from scratch, even a potion master like Snape cannot succeed in one go.

After the new potion was scrapped, Snape closed his eyes and was silent for a moment, temporarily putting down the work in his hand and preparing to take a break.

"If you want to know Animagus, I can recommend someone to you."

Snape's expression was still cold: "As long as she can ask for her help, it should greatly promote our research progress."

Xin Sheng's eyes moved slightly, and he had already guessed who Snape was talking about.

Sure enough, Snape spitted a name out of his mouth.

"Hogwarts's Transformation Professor, a recognized master of transforming techniques in the magic world, registered Animagus, Vice President Minerva McGrath."

...

Although Snape and McGonagall are both deans of the college, they treat students completely differently.

Due to differences in personal personalities, Snape will not stare at his students at any time like McGonagall, and will often adopt laissez-faire.

This gave Snape more free time and allowed him to devote most of his energy to his personal interests.

Professor McGonagall is a rigorous person and is very strict with students.

Anyone who violates the school rules will be punished fairly regardless of the college, and will not be as blatant as Snape's blatant bias towards Slytherin's students.

The relationship between McGonagall and Snape is not bad, but it is definitely not very good either.

Due to the invitation of his colleagues, the busy McGonagall took precious time to come to the screaming shack.

McGonagall had heard of Nagini's existence from Dumbledore and knew that she was a Horcrux that Voldemort had not yet made.

Snape doesn't like to communicate with others, so Xin Sheng tells McGonagall about Nagini in detail.

“Animagus?”

Professor McGonagall frowned and circled around Nagini for a few times, trying to release some detection spells on her.

"There are indeed some similarities to the Animagus deformation, but there are quite a few differences."

Mag was pondering for a moment and turned his gaze to Cialis.

"My schedule is tight and I don't have much time to participate in your research, but I can teach Xiri the tricks of Animagus' transformation."

"I can't take time during the day. After the lights are turned off every day, you come to the Gryffindor Dean's Office to find me."

"As for this big snake..."

McGonagi looked at Nagini's cold snake eyes for a few seconds: "Give me some time, I need to check some information first."

Xin Sheng smiled and expressed his gratitude to McGonagall: "Thank you for your willingness to help us in your busy schedule, Professor McGonagall."

McGonagall pushed his glasses with a plain expression: "I hope your experiment will succeed, after all..."

After a moment of pause, McGonagall, who had always been selfless, showed his emotions rarely and smiled bitterly.

"If this snake was really the Nagini I knew, I wouldn't want her to keep this irrational beast form forever."

...

Time is fair to everyone, but in a fulfilling and busy life, people will feel that time passes particularly quickly.

Of course, this is just a subjective feeling, and it does not mean that time is really passing through these people faster than others.

When Snape reduced the frequency of going to screaming shacks and stayed in school to supervise students, Natiya and Xiri realized that it was already the June final exam season.

The experiment against Nagini is temporarily at a deadlock.

Snape tried many kinds of potions, but it was difficult to lift Nagini's Blood Demon Curse.

Xin Sheng speculated that this curse could not be solved by magic potions alone, and might require assistance with specific deformation techniques.

As the final exam is approaching, McGonagall cannot spare enough time to help.

During the day she had to manage students and before going to bed at night she had to teach Cili to master Animagus, and she couldn't find any free time.

Since there is no breakthrough progress for the time being, Xin Sheng simply put down his research and fulfilled his promise to Dumbledore, and officially appeared in front of Hogwarts teachers and students as an assistant teacher in the Black Magic Defense Class.

Just as Dumbledore said, the old professor Muller is old and plagued by illness, and has long been in short supply and often falls asleep on the way to class.

Even if he can stay awake, his lessons make people sound sleepy and are completely written by the script.

Instructing Natiya and Xiri to continue to stay with Nagini for supervision, Xin Sheng changed into a brand new navy blue magic robe and took over the class when Professor Muller met Zhou Gong again.

Since he is just an assistant teacher for the time being, Xin Sheng does not intend to change Professor Mueller's teaching method.

The drastic reforms will be left until the next school year is officially taken over before implementation.

"Please return to your senses and turn the textbook to page 32. We will continue to explain how to defend against evil curses."

Xin Sheng saw two familiar faces in class, with playful smiles on his face, and he stretched out his magic wand to point at them.
