In the days that followed, Harry was much easier.

At the very least, the gill grass solved Harry's worst fears.

But for the practice of the Bubble Head Charm, Harry did not relax.

In any case, rather than believing in the efficacy of a potion, it is better to have the reality of one's own magic.

Of course, this was also facilitated by Hermione's pressure, and the girl also knew about the effects of the gill grass.

The duration of the gill grass in salt water was different from that in fresh water, and although the deviation was not significant, they did not have extra gill grass to experiment.

The exact content of the mission is not yet known, but for Harry, of course. So.

If something happened underwater, there really wouldn't be anyone to help Harry.

Breathing is the foundation of survival.

"So, Hermione, do I have to practice in the Black Lagoon in the winter?" said Harry, embarrassed.

"This is the most effective way to exercise your bubble head mantra. Hermione said mercilessly.

It was still very cold, at least for Harry.

"You can warm yourself up with a warming spell, it's not as cold in the water as you think. Van Lin said.

"Good. Harry rubbed his arm, and when he took off his clothes, Harry was trembling.

It's so cold that in the spring, there is no snow on the shore, but that doesn't mean it's time to swim.

"Bubble-Head Charm!"

Harry's wand swept lightly across his face, and a misty veil appeared on Harry's face.

"How do you feel?"

"Fresh air......," Harry said, "is that okay?"

"Of course. Van Lin nodded, "However, if you have bad breath, even if you can maintain the spell for more than thirty minutes, it is impossible to exchange oxygen. ”

"What's this?" called Ron.

"I don't know, maybe it's the bad taste of the inventor of the spell. Van Lin said.

"And I'm going down?" said Harry.

"Good. Several of them were wrapped in thick clothes, and in order to keep Hermione from feeling cold, Van Lin even used a warming charm to create a warm space.

What a luxury way to use magic, and it was definitely a bad practice to put it in Professor Snape's place.

But Harry was really envious, it was much better than the way he looked in a short-sleeved shorts.

"Ron, aren't you going to stay with Harry, I think you should get used to it too......"

"Why, I don't need to go into the water...... Ron quickly shook his head and refused, "But don't you want to find those merfolk?"

"Oh, of course, but now it's time to help Harry practice, and if I get out of the water, I think you'll have to get Harry up. ”

"Oh, then you'd better leave later. Ron didn't hesitate to say that it would kill him to let him go into the water in this weather.

Harry's figure walking towards the center of the lake wasn't so shaky because the warm-up spell hadn't expired yet.

It's not much better, though.

The water was so cold that even if the heat of the Warming Charm was controlled by Harry, it was still too much for Harry to maintain the Bubble Head Charm and the Warming Charm at the same time.

"How long do you think Harry will last?"

"It's hard to say if you only maintain the Bubble Head Charm, but if you maintain the Warming Charm, with Harry's mana level, you won't be able to support it for an hour. Van Lin said.

"Not necessarily, maybe it will be exceeded?" Ron said.

"Want to make a bet?"

"Duke Honey's candy!"

"Deal. Van Lin smiled, at this point, Ron was very similar to Fred and George.

"You shouldn't be so bad as Ron. Hermione whispered, and the girl stuck out her tongue cutely, "Duke Honey is tired of eating." ”

"I can get my dad to send some back. Van Lin said.

Hermione nodded, she knew that Van Lin was naturally talking about Mr. Al, and in fact, Hermione was also very unappetizing to eat those sugar-free snacks......

There's magic to take care of, why doesn't she try more.

Minutes and seconds passed.

About half an hour later, Van Lin saw a figure emerge from the water, like a flying fish, but he was still a little far from the shore.

"A dozen multicolored sticks. Van Lin said quickly, and then Van Lin pulled out his wand (a shrunken staff...... Brought back the figure in the sky.

To Van Lin's surprise, Harry was a little blue all over his body, and it seemed that Harry was not maintaining the Warming Charm.

However, in terms of timing, it was a bit of a surprise to Van Lin.

With Harry's magic, support a bubble head charm......

Harry propped his hands on the ground, and with the help of Hermione and Ron, Harry spat out several mouthfuls of water.

It seems that the Bubble Head Charm was lifted even earlier.

"What's wrong, Harry?" Van Lin asked, though he didn't think Harry could last an hour, but it wasn't even thirty minutes now, and he hadn't maintained the warm-up spell yet.

Harry's body trembled a little, and his lips had turned completely blue.

With the help of the warm-up charm, it took Harry about ten minutes to recover.

"It's too cold. Harry came up and complained, he had come to a cold set meal, and a few large mouthfuls of cold lake water poured into it didn't taste so good.

"I lifted the warm-up charm shortly after I entered, and I tried to dive down. ”

"You've been attacked?"

"The underwater pressure was too much, and my bubble head spell didn't hold, and I still used the last bit of magic to rush up. Harry said that he hadn't used the warning that Van Lynn had given him, at least not to the point where he had lost consciousness.

However, this gave Fan Lin enough reminders.

The pressure under the water must also be taken into account, and if the Bubble Head Charm is not tough enough, it is also a load for the wizard.

Harry had used the Bubble Head Charm for about forty minutes on his second attempt, almost doubling the time, but it was the first time he had gone that deeper.

This is just a state of pure swimming, you must know that he is going to the territory of the mermaid, and the battle is naturally inevitable.

The final decision was for Harry to take Houttuynia with him and see if the time was right to use it.

However, Van Lin still felt that it was good to use it from the beginning, after all, it is impossible for the human body to swim faster than a fish.

After getting Tfrey's assurance, Van Lin didn't want Harry to waste much time on the second task.
