"Faint!" Louis said silently as he pointed his wand at Grindillo, and with a red light, Grindillo fell unconscious.

This is where Louis's silent magic skills come into play. In the water, wizards are unable to pronounce spells accurately, which is one of the main reasons why silent spellcasting was developed as an advanced magic technique.

Unfortunately, the Grindillo fell, but more Grindillo swam towards Louis.

"Damn, why didn't Dumbledore clean up his lake!" Louis grumbled mentally.

It's not impossible for Louis to get all of these Grindillo one by one, but it would be too time-consuming and magical, and some of the gains outweigh the losses.

"Dragon's Breath!" as another Grindy Low was stunned by Louis, he chased the tip of his wand at him.

Grindilow, who wanted to continue to pounce, suddenly became hesitant, and they did not dare to approach Louis at a distance of about ten meters.

Louis ignored the Grindillowe, and he moved quickly towards the deeper part of the lake. Originally, he still had plenty of time, but the magic of 'Water Dragon's Breath' was too mana-intensive, although it could effectively make those Grindillos dare not approach him, but it needed to consume a lot of his own magic power to simulate the dragon's breath, which meant that his magic power was slowly decreasing, which meant that he had to speed up his speed.

Louis continued to move towards the bottom of the lake for about ten minutes, and at that moment, the mermaid's song rang in his ears.

"There is only an hour to find and know more about the objects we have taken. ”

Louis knew he was in the right place when he heard the voice, and he moved quickly towards the source. As he moved, he noticed a large rock in front of him, and on that rock was depicted a number of merfolk with spears in their hands, chasing something that resembled a squid.

"Don't delay any longer, be careful that what you're looking for rots here. ”

Under Louis's search, he finally found a lot of rough stone dwellings, covered with algae, maybe this is the decoration that mermaids like?Through which stone holes did he see some mermaid faces........ If those young boys who fantasize about the beautiful mermaid girl see this scene, they must be disappointed.

The skin of mermaids is different from that of humans, their skin is iron-gray, and their dark green hair is unkempt, like a pile of seaweed. Their eyes are yellow, their teeth are yellow, and they wear pebbles strung with thick rope around their necks. As Louis passed by them, he could clearly feel the smell of decay coming from them. Some of the merfolk who were far away even ran out of their distant burrows to see him, with long fur in their hands and slapping the water with their silver-white tails.

Louis ignored them, and continued to move forward quickly, and as his voice became clearer, he noticed a village-like place ahead. Many merfolk sang in one square after another, and that song was the song that attracted the warriors.

And in the middle of them, there was a huge mermaid statue, and the mermaid statue had four people tied to its tail.

Ron was tethered to the far left, Hermione was next to Ron, and the third was a little girl up to eight years old, who was clearly Harry, Krum, and Fleur who needed to be rescued. And the fourth one who was tied up was actually Ginny, although Louis made it clear that he refused to let the little maid be trapped in the lake, but he didn't expect that Ginny was tied here instead of the little maid.

Maybe Dumbledore thought that Louis had saved Ginny once in his second year anyway, so it didn't make much difference to save another one?

Louis shook his head, putting the miscellaneous thoughts behind him for a moment, and he had to get the people out first, anyway. Louis moved to Ginny's side, and with a wave of his wand, the rope that bound Ginny fell off of its own accord. He couldn't help but think that his set of skills was really getting more and more proficient, and it was worthy of the fact that he had studied and practiced so hard for so long in order to take off girls' clothes, and it could only be said that it was worth it!

Louis took Ginny in his arms, and I have to say that Ginny, who is already in the third grade, is actually developing well. She usually wears a school robe, which really makes Louis look away.

But then Louis sighed, and it was clear that the little maid would not let him go when he came ashore. Damn Dumbledore, why can't you just let a man down......? It seems that after the man comes down, Linda's side will be even more unclear?

Just as Louis was about to leave with a depressed face, the corner of his eye glanced at the girl who was at most eight years old. Obviously, when the referees dropped the private man, they only cast a sucking spell on them, so that they would not drown, at most they would be a little cold. This is understandable, after all, if you want to pretend that they are tied in, you can't still be entertained with delicious food and drink, right?

But apparently they had forgotten one thing, and although the little girl was not going to drown, she looked so cold that she was already cold, and her face was slowly turning purple. Louis wasn't sure if she would really have a problem when the hour was over.

Everyone knows that the Triwizard Tournament is very dangerous, but this is just for the warriors, and a little girl can't be allowed to lose her life for no reason. It was her sister who participated in the Triwizard Tournament, and it wasn't her, so she had no reason to die for her sister.

Although Louis didn't think he was a good person, he couldn't do it to see an innocent little girl die like this. After all, this little girl is not his enemy or anything, and it can be said that he can save the little girl now.

He waved his wand at the little girl and cast a thermostat to protect her from freezing to death.

But then Louis's brow furrowed, and he found that the temperature at the bottom of the lake was too low, and the effect of the thermostat was very poor, lasting at most ten minutes. In other words, even if he cast the thermostatic spell and left, after ten minutes, the little girl was still in danger of freezing to death.
