Chapter 228 Underwater Rescue
Andrew never thought that one day he would be so free as to jump into the Black Lake, especially in winter, but after getting underwater, he found that it was not as difficult as he thought.

The fever-generating potion made him feel his body was extremely hot, which allowed him to quickly adapt to the low temperature of the lake water. The lake water, which should theoretically be bone-chillingly cold, now became a coolant to keep his body temperature normal, and even made him feel a little comfortable...

"Damn it, how on earth did those guys prepare? They even made a special potion in the past few days..."

He held the rope made of water in his left hand and cast a spell on his shoes with his right hand - as an obvious pulling force came, he began to continuously use water to transform into a rope to make sure he would not lose his way.

Thanks to the pair of shoes that were as heavy as iron blocks, Andrew sank very quickly. It was not until the dark lake water below became shiny that he began to cast transformation spell on his shoes again to ensure that his speed slowed down.

“This visibility…”

Andrew complained under the bubble head curse.

He waved his wand and began to collect seaweeds, and used them as raw materials to make fluorescent herbs (he had not yet researched more effective lighting techniques, so he could only use the herbs he had practiced this year).

Although the brightness of a single piece is not that satisfactory, when a large section is combined together, plus a lighter piece of driftwood, held in Andrew's hand, it looks like a large balloon and is particularly eye-catching in the dim lake bottom.

Andrew used Transfiguration to lengthen the rope, then waved his wand to create an undercurrent to propel himself, and began to search the bottom of the lake quickly.

He didn't expect any treasure. The most important thing now was to get all the people together as soon as possible.

Fortunately, his image was quite conspicuous in the dim lake bottom - within a few minutes, he was stopped.

"Dude, why are you so presentable? Did you lose it? What did you find...ah, Taylor?"

"it's me…"

Seeing the three of them holding wands and lighting up with the Bubble Head Curse made him angry, "Who told you to go to the Black Lake in winter! If someone hadn't reported it, I would have had to come down to retrieve the bodies!"

The other party had basically no intention of resisting - this made Andrew a little less angry.

He ordered the three men to follow him, and then began to look for the next group.

This time it was a little slower, taking about five or six minutes.

The Hufflepuff group was more obedient, but Andrew didn't plan to let them stay underwater. He just let them swim all the way up along the rope.

'Shit, I'm almost halfway through my potion time... only three sets left..."

He was a little anxious, but soon a huge ball of air floated over - even from a distance, he could feel that the water flow was being controlled by someone.

In the huge air mass, the figures of Dumbledore and nine students were particularly attractive.

"Tyler?"

Dumbledore's voice was distorted by the air mass. "Why did you come down here?"

How did I get down?
You didn't make me...

Andrew finally calmed down - he suddenly remembered that Dumbledore's order to him was to go to the Black Lake and stop them.

So, Principal, are you here to rescue them personally?

While he was thinking, he was wrapped by the bubble.

Dumbledore looked at him with a kind expression, "Have you asked how many people have come down?"

"Fifteen, five from a team of three, if they remember correctly..." Andrew released his bubble head spell, "the remaining six are floating up along the ropes."

"Well, send this batch up first, and we'll look for it again." Dumbledore nodded, and the bubbles separated, and he began to float up with the nine people along the water rope Andrew had made.

"Really..." Andrew sighed, "A new trick every day..."

"This is what youth and vitality mean. If they become lifeless day by day, they don't look like young students anymore."

Dumbledore exclaimed, and Andrew wanted to roll his eyes.

Who is so lifeless, Principal!

You didn't notice the trouble I caused. If you had noticed, you would know what vitality is!
But he obviously couldn't show off such words that were beneficial to the Astronomy Tower. He and Dumbledore simply started searching along the bottom of the Black Lake separately, and then floated towards a fixed location with Dumbledore.

Soon, Andrew saw a huge stone with something like a mural on it - he didn't know what that waterproof paint was, but he could see it very clearly. It was a group of fishmen catching squid-like creatures.

Soon, they came to a simple underground residence - a group of stone huts with some algae-like things hanging on them as decorations. Among these rough buildings, mermaid-like creatures poked their heads out one by one.

Yes, mermaid-like - because they completely subverted Andrew's perception of mermaids.

Apart from the human head and fish body, they are nothing like the legendary fishmen. They have rough skin, crooked teeth, and a necklace made of messy pebbles around their necks. The most terrible thing about them is two things - first, they are ugly, and second, their hair is green...

They obviously knew Dumbledore. After a roar that Andrew couldn't understand, a particularly strong mermaid appeared and stuck half of its body in to communicate with Dumbledore.

...

"No more. The mermaids said they only felt those people...it's a perfect ending."

Dumbledore smiled, and the bubbles they were in began to rise rapidly. "The squids that prevent drowning were actually attracted by some magic potion feed... The method they came up with is really..."

...

Feed, potions...

Andrew was too helpless to complain - could this group of people be taking it seriously? They actually thought there was a secret treasure under the Black Lake?
By the way, isn't it because of this that someone dug a lake for no apparent reason? That's too funny.

The Black Lake and the Secret Treasure…

If he had known that the students were so crazy, he would have just asked Dumbledore to dig them out and be done with it, so that they wouldn't have to keep thinking about it!
Soon, the bubbles surfaced, and Dumbledore and Andrew reappeared in front of everyone.

The unfortunate ones who had fallen into the water were now busy using magic to dry each other out, but it was of little use - there were no special spells to deal with it.

Fortunately, the potion seemed to still have some power, which made them look less embarrassed.

"You handle detention, Tyler."

Dumbledore nodded at Andrew, then turned and left.

'I? '

Andrew, who had just breathed in fresh air, was stunned for a moment, and then he felt unwell.

No, Principal, it’s okay if you run away at other times, but why are you running away now?
However, when Dumbledore left, everyone looked at Andrew seriously all of a sudden - No, buddy, are you serious?
Becoming a class monitor in the second grade?

Are you kidding me? How did Hogwarts become like this?
