In the end, Ernst did not cast the spell directly on Alexander.

After he pointed the silver stick in his hand at the other party, soon he saw that he suddenly shook his hand again, and a flame rushed straight to the dark sea in front of the change.

"Boom!"

The extremely high temperature instantly evaporated a large amount of seawater, causing a quite strong steam explosion. The white steam suddenly expanded, and even Ernst himself was surprised.

Obviously, he didn't expect such a big reaction when the high-temperature flame came into contact with water in an instant - a situation he hadn't encountered before when he practiced secretly.

To be honest, this is much more than what you can make when you attack with a high-temperature flame!

"This... What is this?"

Facing Alexander with a shocked face, Ernst looked at the silver staff in his hand, and then raised his head and said:

"It's just a fire mantra."

"What?"

While Alexander looked carefully from shock to meditation, and then from meditation to staring at the silver stick in Ernst's hand, the door connecting the cabin and deck was suddenly pushed open, and a figure came out quickly like a gust of wind.

"Oh! What are you doing? What happened just now?"

Leng buting rushed out of Professor McGonagall, and pansy, who ran to report to her, followed her. As for Noah, who has been hiding behind the door since just now, he is still standing on the stairs inside the door!

"Hey, little fat man, make way! Let me pass -"

There was a murmur, and then Hagrid, too, stooped out of the door and appeared on the deck with his broken umbrella.

"Was that an explosion just now?"

Professor McGonagall quickly and calmly came between Ernst and Alexander and looked around at the dark sea around the change, obviously looking for any suspicious figure.

But soon, her eyes were also attracted by the silver stick in Ernst's hand.

"Snake stick?"

Yes, the carved features on the walking stick are so familiar to the Hogwarts that they can usually be directly associated with a "big man" at the first sight.

In the face of the current principal, Ernst, who has always been a bit of a maverick, can't help but be a little nervous. After all, he was still thinking of leaving here secretly until just now!

And that, of course, is something the other party will not allow.

"Well... Professor McLean knows that he allowed me to carry it."

"Well, of course, I can trust you," McGonagall looked at him and nodded slightly. "Things like this usually can't escape his eyes. He doesn't know it's strange."

As he spoke, Professor McGonagall suddenly frowned again and then turned to say:

"So that means... You made the explosion just now?"

As soon as Ernst heard this, he immediately regretted - why did he have to mention it in front of Professor McGonagall? Is it difficult to worry about being taken by the other party?

What kind of person Professor McGonagall is is clear to all the teachers and students in the school. Obviously, she won't do that.

That's good. Just a little flustered, he said more words, which may have been roughly guessed by the other party along the beginning of the conversation.

If you ask the other party to think more, it is estimated that even what he wants to do will have to be speculated.

"Professor McGonagall, I just wanted to practice the duel with Alexander, and then I tried its power. I just didn't expect that there was too much noise when I wasn't careful..."

At this point, Ernst paused for a moment and was waiting to explain. But before he could say more, he was immediately interrupted by Alexander on the other side.

It can be seen that after hesitation, the latter suddenly interrupted:

"Professor McGonagall, no! Ernst, he wants to leave -"

"Alexander!"

Seeing that he was about to be told his true purpose by the other party, Ernst couldn't help staring at him and called him like a warning. However, Alexander did not seem to have the intention to keep a secret for him as he had done.

"Ernst," Alexander said seriously, "listen! Even if your strength... Or the strength of this walking stick is indeed beyond my imagination, it doesn't mean that I agree with you to run to the front line of the current war and die!"

"Alexander..."

Seeing that he finally told the truth, Ernst shook his head helplessly. He didn't even know what to say for a moment.

When he was speechless, Professor McGonagall said:

"Are you going to the front?"

Ernst did not speak, but Alexander took the initiative to say to MEG as if he were speaking for him:

"Professor, to be exact, Ernst wants to find the ancient black wizard halbo! Oh, seriously, I don't know what he's thinking."

When MEG heard the speech, he first gently nodded at Alexander, and then looked at Ernst and said:

"No matter what reason you have, I can't agree to this. I think you should know, so you don't want me to know. But I still hope you can say what you want to go for?"

Ernst probably realized that it would be difficult to hide today, so after thinking about it, he finally gave up and continued to hide.

He answered:

"It's because of this walking stick - you must know, it was brought out of an underground tomb in the deep mountains and forests. And that tomb is halbo's tomb. In fact, it's the magic walking stick used by Salazar Slytherin when he suppressed halbo."

"I remember at that time, it was the magical image left by Slytherin that entrusted it to me."

As he spoke, Ernst couldn't help spreading his hand.

"Now, Haier Bo, who escaped from the ground, is raging the whole world. I feel that I, who accepted this walking stick, have the obligation to deal with that despicable Haier Bo on behalf of Mr. Slytherin."

Not to mention tynes's words of "dealing with Haier Bo", MEG shook his head after hearing what tynes said.

"To be honest, although almost all my knowledge of halber comes from McLean and Mr. lupin, I still have to say that the gap between this powerful ancient black wizard and you can't be filled by a stick from Slytherin!"

After that, Professor McGonagall taunted her face and continued to lecture Ernst. After the persuasion, she said again:

"So, stay on the change! Your friend Alexander is right. You must not act rashly - it's true that you'll lose your life!"
