HP: After binding to the strongest wizard development system

The system resides in the depths of Till's brain. It is there wherever Till goes. Naturally, the system cannot see what happens in a place where Till is not present. Fortunately, the system still has a huge database that can be searched.

After skillfully bypassing the permissions set by the main system, the system has just found some clues that may be useful to Thiel.

Before Till's mood could get even lower, he heard the system continue: [Three days ago, the Hogwarts Express was inspected and there were many wizards walking on the train. Yesterday, the train left Hogsmeade Station and stopped at platform 9. After that, a few people got on the train and left in just ten minutes. 】

The database is as huge as an ocean, and the system can find relevant and useful clues in just a few minutes, which is already very good.

If there is enough time, it can slowly find out who is doing the trick and know the whole process, but Till and the others are already anxious and upset at the moment, and the system can only solve it quickly.

After all, it would take at least four or five hours to screen all the data. But with the clues provided by the system and leaving it to the professors to find the truth, four or five hours would be more than enough.

The only problem is how Thiel can reasonably tell the professors the clues the system told her.

After thinking about it for a while, Till couldn't find a suitable reason to lead out this clue. However, Professor McGonagall seemed to have thought of something and walked out quickly for a few minutes. When he came back, his expression became more relaxed: "There are passengers on the express train." It’s recorded, it’s automatically recorded for everyone who gets on the bus, and it’s on the driver’s side.”

"I just went to see it. In the past ten days, there have been more than fifty names of adult wizards. Most of them are maintenance personnel sent by the Ministry of Magic, but there are still a few who secretly got on the bus yesterday. , is not recorded by the Ministry of Magic." Professor McGonagall showed a smile, "I think the answer will surface soon."

The Hogwarts Express was stolen and some items that could harm the students were left behind. This situation cannot be solved.

Professor McGonagall notified Professor Dumbledore directly, and then called all the prefects and two chairs, asking them to start patrolling each carriage to check whether there was any powder on the students.

Till was not sent out to carry out this temporary emergency mission. Professor McGonagall held a handkerchief and asked her to go to the end of the carriage with the two professors to see what the words written in powder were.

Professor McGonagall was anxious. It was Teal who was leading the way. As they walked, Professor McGonagall was a few steps ahead of them, while Teal was lagging behind, walking side by side with Snape who was catching up.

"Don't worry, we are here." Snape knew that Till was not feeling stable, so he secretly shook Till's hand under the cover of his robes as they walked. He held it quickly and released it quickly, and no one would notice this quietly intimate action.

Teal turned her head and glanced at Snape. The brief exchange of glances allowed her to see the comfort and concern in Snape's eyes, and the uneasiness in her heart dissipated slightly.

Although she was still uneasy, at least she was not alone.

The two professors and the famous Thiel were walking along the corridor of the train. There were also many prefects with serious faces, and they began to inspect the students' clothes in one car after another. What exactly were the prefects looking for? The students were not informed - a tense atmosphere quickly spread on the train.

Bill has graduated, but the carriage where Mgina and the others are sitting is not deserted. The three younger brothers of the Weasley family - Percy, who enrolled last year, and Fred and George, who enrolled this year, are also sitting with Mgina and the others this year. Together.

When Charlie entered the carriage and started to check everyone's clothes, his expression was more serious than ever before, and he whispered to them not to ask any more questions. The two twins who originally wanted to play with their brother for a while suddenly became quiet.

Mgina watched Charlie carefully and carefully look at everyone's school uniform, and nervously held the hand of her fiancé who was still having conflicts: "I don't ask you what happened, I only care about what happens between you and Tier. There's no danger. Where's Teal?"

Charlie touched Mgina's face and sighed: "Don't worry about us, Professor McGonagall and Professor Snape are here, and Till is with the professor now."

Not counting Snape for the time being, Professor McGonagall's status in the minds of all students was different. With her presence, everyone immediately relaxed.

Mgina nodded, but did not say whether she was relieved or not. Charlie still had many carriages to inspect, so he didn't have time to stay long, so he left quickly.

At the end of the train, the worried Thiel and the two professors walked into the carriage filled with luggage. There was no need for Professor McGonagall to speak, Till directly pointed in the direction, and the three of them just took a few steps and saw the powder writing on the corner of the wall behind the luggage.

"That's it!" Snape took two steps back suddenly. If Teal hadn't quickly grabbed his hand and asked him, who turned pale for a moment, to come closer to her, Snape would not only knock over the pile of luggage, but also He will also be knocked off his feet.

There were no outsiders here, and Professor McGonagall knew about Till and Snape, so Till let himself and Snape hold hands tightly, hoping to comfort Snape.

Professor McGonagall immediately looked at him: "What's wrong with this sentence?"

Snape opened his mouth, his face was pale, but his eyes were red, and he was speechless, unable to say a word.

The moment he saw these words, Snape's heart almost skipped a beat.

"Voldemort said it before." Teal sighed and helped Snape answer Professor McGonagall, "I heard it from my parents."

The Emery couple rarely concealed anything from Till, not to mention Till's expression at this time was extremely calm. Professor McGonagall had already believed Till's excuses without even thinking of asking the Emery couple for confirmation.

Voldemort's words were written here with ceratopsian powder that could hurt people. Professor McGonagall's face became ugly again, and this time it was even more angry.

As a professor who loves and values ​​his students, Professor McGonagall cannot tolerate such a thing happening on an express train full of little wizards!

"We can't let this powder stay." Professor McGonagall immediately made a decision. After asking for Teal's opinion, he used the handkerchief stained with powder to wipe the powder on the wall.

Till watched Professor McGonagall step forward. When the handkerchief was about to touch the writing, a huge panic surged in his heart. The system in his brain also detected that something was wrong at that moment, and exclaimed to Till.

【Host! Stop Professor McGonagall quickly! 】

Teal did not hear clearly what the system said. When he had a premonition, Teal had already strode forward, grabbed Professor McGonagall's robe, and pulled it back while the magic power condensed on the wall, forming a thick layer of barrier.

This barrier was something Teal learned from Grindelwald, and evolved from a little trick he once taught Teal to protect furniture.
