When Xin Sheng first started as Professor Mueller's assistant, lower grade students were highly receptive to him, and just using some fancy spells could attract their attention.

The seniors are not so easy to fool. They have already stepped into the magical world of adults with half their feet, especially the pure-blooded students of Slytherin College.

Since childhood, they have received elite education, they no longer look down on Hogwarts' "playing house" teaching methods, especially this year's professor of Black Magic Defense Class, Mueller, is so... bad.

When Xin Sheng first taught students in grades 6 and 7, his too young appearance made these young wizards quite disdainful of them.

After experiencing experiences in many different worlds, coupled with a lot of messy things such as reshaping the body, Xin Sheng couldn't remember how old his soul was.

Anyway, he was at least 35 years old and his mentality was already mature enough. The students' ridicule and ridicule did not cause him too much psychological fluctuation.

In just one class, Xin Sheng reversed the first impression of these older naughty kids about him with his strength.

No matter which career or career you are in, without overwhelming personal connection advantages, you will still respect your personal abilities.

As the saying goes, a gun strikes a bird.

The proudest senior Slytherin was targeted by Xin Sheng, which also attracted Snape's dissatisfaction protests.

Xin Sheng ignored the old bat's poisonous tongue and still gave lessons to students of all grades at his own pace.

Since the progress is lagging behind, Xin Sheng can only make adjustments and try to leave a deep enough impression on the course content in the students' minds.

Without violating the standards of corporal punishment, Xin Sheng caused some trouble for senior students in the name of teaching, and deepened their understanding of the course by practicing it.

As for the protests of the students’ parents?

Xin Sheng greeted Dumbledore before catching up with the progress. For the sake of the students' grades, his teaching method may be slightly excessive.

All the yelling letters sent by parents were stopped by Dumbledore, and Xin Sheng could continue to maintain high-intensity teaching in a relatively relaxed external environment.

This is also a last resort.

On the eve of the final exam, Professor Mueller, who had been persisting for a whole year, finally couldn't hold on.

He suddenly fell ill in class and was rushed to St. Mumph Pomfrey, a school doctor who rushed over to hear the news, rushed to St. Mungo Magic Hospital.

Although he was lucky enough to be rescued from the Gate of Hell, Professor Muller must not be able to catch up with the final exam.

Under Dumbledore's arrangement, Xin Sheng replaced Mueller as an assistant teacher and completed the final exam of the Black Magic Defense Class of all grades this year.

Fortunately, the result is pretty good.

The death sprint in the last period rushed back a lot of progress. In addition to a few poor students who did not want to learn, the failure rate of each grade was only above the average of previous years.

However, Xin Sheng was not very satisfied with the result and decided to give these poor students a good ideological education class next year so that they could "willingly" change their minds.

...

After the final exam, the results of the Academy Cup were finally released.

The Academy Cup of the year is still won by Slytherin College.

Aside from the unpleasant and arrogant attitude of Slytherin students, these young wizards who have received family education since childhood did perform better in class than other colleges.

The absolutely neutral Xin Sheng had no interest in the camp battle between pure-blooded wizards and mixed-blooded wizards, and maintained an objective attitude to add points to the better performers in the classroom, most of whom were Slytherin students.

In private, many students from other academies complained that these pure-blooded wizards have innate black magic talent, and naturally they will be easier to use in black magic defense than others.

Xin Sheng did not refute the students' complaints in person, but he told Dumbledore about the class opposition between the colleges.

As for how Dumbledore would deal with it, it is not something that Xin Sheng, a teaching assistant in a single discipline, can interfere.

Sending off students from various academies, the noisy Hogwarts suddenly became deserted.

Although professors can't completely relax during the holidays, they at least don't have to be as busy as they did when school starts.

McGonagall and Snape rejoined the research team against Nagini and soon made a major breakthrough in the experiment.

After more than two months of study, Xiri has learned all the tricks of Animagus' transformation, but only the final practice is left.

Maggo, who has always been rigorous, couldn't help but praise Xiri's talent for transformation, believing that she is the most outstanding transformation genius in the past century and is likely to become a master of transformation genius who surpasses her in the future.

Xiri does have a personal unique understanding of the transformation technique. After discussion and research with McGonagall, she put forward a relatively novel point of view.

"Although the Blood Curse is a curse, it is essentially a deformation that is difficult to control."

"If we reversely deduce the principle of Animagus and specifically customize it with Nagini's personal conditions, is it possible to transform her from the Orochi form back into humanity?"

"Well..." McGonagall lowered his head and pondered: "It is feasible in theory, but there is still a problem that needs to be solved."

"No one of us can accurately tell the specific physical data of Nagini when she was a human, such as how tall she is, how much weight she weighs, and how much her measurements she is."

McGonagall said cautiously: "Transformation is a very rigorous discipline, and as long as there is a little deviation in the deformation process, it can lead to catastrophic consequences."

Natiya, who was watching by the side, asked a question casually, but she just came to the point.

"Since Nagini was a human before, it means she has muscle memory between the giant snake and the human form transition."

"If we can induce her to use this memory unconsciously while losing consciousness, it may help her to return to the correct human form smoothly."

Snape's face moved when he heard this, and his eyes looked at Natiya with a strange look.

‘This young man can’t tell a truth if he says ten words in his usual way. Why can he put forward such constructive opinions at critical moments?’

If Snape raises this question directly, Xin Sheng will be able to answer it soon.

Because of the sixth sense.

For people like Xin Sheng and Natiya who have high concentrations of Yishu bloodline, the sixth sense is by no means just a mysterious statement, but a special prediction called "knowledge" that actually exists.

Xin Sheng and Natiya's sixth sense will not work at any time, but at some important moments, the sixth sense "knowledge" can unexpectedly give them inspiration to break through the status quo.

Snape said thoughtfully with his chin on his hands, "I can use potions to induce Nagini's muscle memory, but before that..."

Snape turned his gaze and looked at Xin Sheng: "We must first remove the impurities in her soul, those soul fragments with unknown powers."
