On the shore, it was already afternoon. The students were hungry and Ludo Bagman's explanation became weak, but no one chose to leave. The competition was gradually coming to an end. Most of the warriors (except those caught by the mermaids) had obtained enough golden gems. They only needed to rush to the last location and gather together to successfully complete the competition.

"In the third hour of the competition, the warriors were seriously exhausted. And as the first warrior successfully gathered the golden gems, the mermaid tribe went out to patrol the Black Lake, and the warriors' situation became more dangerous." Bagman said hoarsely.

Felix stood by the lake and touched his nose. He didn't know if the mermaid leader had misunderstood his meaning of giving him the magic phonograph, so he became extra hard-working. An hour and a half ago, the mermaid guards led the tamed Grindylow and galloped in the Black Lake, capturing the exhausted warriors one by one.

Those who were not caught at the first time also hid and dared not show up.

...

Ron breathed a sigh of relief. He finally passed the level. He didn't know if this could be considered a loophole he found, but he found that if he didn't succeed once, he could continue the second and third time... And he also discovered the second secret. Only when he rotated to Muggle Studies and History of Magic, he could choose to open the book or close the book.

After knowing this secret, he found the most suitable method for him to pass the level - keep choosing blue levels, and when he encounters these two items by luck, choose to open the book, and then flip through the book to find the answer. He may fail two or three times in the middle, but he will definitely succeed. After passing the

level, choose the nearby terrain to find the location of the golden gem.

He yawned, and Ron felt that he seemed to have forgotten that he was in a dangerous competition, but returned to the classroom. He was very glad that he had read "The Adventures of Little Wizard Mick" over and over again, and he knew a lot of things...

The blue level and the purple level both have their own protective shields. This is a rare safe area. Ron took a deep breath and prepared to find the seventh golden gem. As soon as one foot stepped out, he found a tall and burly figure swimming past him.

That was the warrior of Ugadu. Ron turned his eyes to the direction he came from. He saw a group of mermaids chasing him aggressively. Ron grinned and retracted his outstretched foot.

Unfortunately, a mermaid found him. The tall mermaid blew the whistle on his chest. Three mermaids stayed and surrounded him. Although mermaids are generally ugly, Ron recognized the leader by his clothes and bone decorations.

Ron swallowed his saliva. He seemed to have kicked him.

The mermaid obviously recognized Ron, grinning and showing his fangs, and laughed happily. At this moment, several spells illuminated the water. The

two mermaids fell to the ground in an instant, and their hair like braids fluttered on their heads. Ron raised his wand and recited the coma spell.

The light of the coma spell pierced into the water, and the speed was obviously slowed down, but it was still close, and the spell successfully hit the leading mermaid. The mermaid looked at Ron in disbelief, and fell into the mud after a moment of stunned.

Harry and Hermione came out from the corner.

"How did you meet each other?" Ron asked with a bubble head curse.

"After collecting seven golden gems, the watch can show the location of your companions. It is three small red dots. I guess the tracking spell must have been cast... I found Harry first, and wanted to come to you immediately, but encountered a large number of mermaids... They are too flexible in the water. Harry used the light of the Patronus to scare them, and we took the opportunity to escape..."

Hermione explained, and then looked at Ron, "By the way, how many golden gems do you still need?"

"The last one, and I already know the location." Ron said hurriedly.

"Then let's hurry up," Hermione said palely, "It's been too long, I don't know if we are the last group."

"Definitely not," Ron said, "I just saw a warrior from Ugadu, he was chased by a group of mermaids."

"Oh, I guess he can't escape, unless--" Hermione said pessimistically, suddenly widening her eyes, and a loud noise came from not far away, and sand flew.

"Hermione, you and Ron go find the gems, I'll go check the situation." Harry said.

They separated quickly, and a few minutes later Ron and Hermione successfully found the gem, but the noise outside was getting louder and louder, and the shouting spread far in the water.

After a while, Harry came back.

"Go!" he shouted, his expression was very terrified. "What's wrong?" Ron asked in confusion.

"Talk as we go!" Harry said decisively, and they rushed towards the last position. The galloping sound behind them was getting closer and closer, as if there were thousands of troops chasing them. A high water tornado engulfed a lot of mud and sand, forming a yellow-brown vortex.

"Several groups of warriors reached a cooperation. They rushed into the Mermaid Square and rescued all the hostages. I saw Durmstrang, Ilvermorny and Cedric!" Harry said with the human armor charm.

"And Ugadu." Ron said palely.

"How did you know?" Harry asked casually, they were getting closer and closer to the target.

"I saw the elephant..." Ron said with a dull look.

Harry and Hermione couldn't help but look back. A few hundred feet behind them, a bright light illuminated the bottom of the lake (Harry guessed that Cedric had used illumination magic). An elephant kicked its hooves and rushed forward, scattering mud and sand, and thoroughly muddying the bottom of the lake. There were more than a dozen people sitting on the elephant. Just what he saw were Cedric, Collins, Roger, Krum, Fleur, and two other Uagadou warriors.

"What should we do?" Ron asked hesitantly.

Less than two hundred feet away from them, a high platform stood at the bottom of the lake, flashing and attracting their attention.

"You go first." Harry said.

"You don't want to be a hero, they will be fine..."

"No," Harry hesitated, "I know they will be fine, I just want to use a magic. You go quickly, I'll come right over, this time we must be the first!"

"Then use it quickly, we'll wait!" Hermione said impatiently.

Harry took a deep breath and held his wand horizontally. He had now fully recovered his normal magic power and could exert his full strength. The key point was that when Professor Hep was hurrying on his way with a silver cloak, he happened to see...

This made him see more possibilities for this spell.

"Hu-God-Protect-"

A huge silver light exploded, and a silver physical patronus stepped on the silver waves and rushed towards the direction of the elephant. There were hundreds of mermaids surrounding it, and more grindylows and several sharks formed a huge encirclement.

After reciting the spell, Ron pulled Harry to the platform. On the other side-

"What should we do?" Collins asked.

"Does anyone have any more ice bombs?" Cedric asked.

"All used up," Byers replied.

"Let's charge!" Graves shouted, his face as white as paper. Of course, it could also be because he had been in the water for a long time.

"Look over there--"

A huge silver stag rushed over. The lake water had no effect on it. It quickly passed by everyone and stood between them and the mermaid, emitting circles of silver ripples. The mermaid had never seen a patronus before, and for a moment she didn't dare to get close. She looked at the big guy who suddenly appeared vigilantly.

"Let's go! Use Transfiguration to buy time!" Cedric was the first to wake up. He recognized this patronus.

The elephant galloped again. The rocks and water plants behind it turned into hounds, shields and ropes under the effect of Transfiguration. They ran all the way to the platform.

Harry, Ron and Hermione sat on the platform, exhausted.
