Hogwarts Summoning Guide.

Previously, with +2 affinity, Bai Lin easily gained the approval of the friendly Phoenix Fox, but hoping to befriend the Basilisk and Fire Dragon with +8 or +10 affinity in the future is wishful thinking.

Grindelho swam around Bai Lin, his face, which resembled a big-mouthed frog, gradually becoming familiar with Bai Lin's appearance and aura, from some confusion and ferocity.

Bai Lin stretched out his finger and gently scratched the belly of Grindylo beside him. The little thing chuckled and twisted its tentacles, looking very happy.

Speaking in the water is difficult, but not entirely impossible. After gesturing for a while, the White Scales finally understood that the Greendylows wanted them to help "play a trick" on a human wizard who had just jumped into the lake. They first spotted Black not far away, and after gesturing for a while longer, the White Scales finally made them understand that it was another wizard. Then they scattered in a flurry.

The vast Black Lake stretches for miles, making the search for a person or even a mouse seem like looking for a needle in a haystack. Even the village of mermaids would be easier to find. However, since Bai Lin had sneaked in during the summer vacation to seal away a few mermaids, he didn't go near the underwater structures carved into the shape of conch shells or snail shells.

Finally, a Grindylow brought news, and Whitescale quickly met up with Black and swam in the direction the Grindylow pointed.

After swimming for quite some time, they should have been close to the center of Black Lake when they heard a churning sound in the water in the distance. A figure was being surrounded by dozens of Grindelwalds in the water.

"Peter!" Blake's eyes widened, and he swam faster toward that spot.

Peter Pettigrew, with his short and chubby body covered in bubbles from the Bubble Head Charm, was being tormented by the Grindylows, who were throwing out all sorts of spells. But the Grindylows swam so fast that most of the spells missed.

Black aimed his "Divine Strike Without a Trace" at Peter. He didn't want to use a sleeping spell to knock Peter unconscious; he had a strong urge to hurt him and make him suffer.

However, the Divine Blade Spell had no effect underwater. The underwater resistance was too great, and by the time the blade reached Peter, it had lost all its power, which allowed Peter to spot the two people rushing towards him.

Peter was terrified. He aimed a Cruciatus Curse at Black and, without caring whether it hit or not, shoved past the Greendylows and swam toward the depths of the lake.

Bai Lin forcefully shoved Blake aside, allowing him to avoid the Cruciatus Curse. Blake smiled sheepishly at Bai Lin; he had never fought underwater before and had made a mistake.

Bai Lin swung his legs and chased after him.

Peter was indeed a good swimmer, but he couldn't compare to the speed of a mermaid. The distance between the two was gradually closing, and Bai Lin was confident that he could disarm him in one move if they got any closer.

Just then, a huge dark shadow leaped up from the deep lake bottom. It nearly hit Peter, who was tumbled several times by the waves. Upon closer inspection, he saw that it was a giant octopus about the size of a truck.

[King Octopus: Level 9 creature, the overlord of Black Lake. It should live in the deep sea of ​​the Arctic, but for some reason, there is one in Black Lake. It has even adapted to freshwater, is a neutral creature, possesses immense strength, and no one dares to provoke it easily.]

Clearly, the three had entered the territory of the Tyrannosaurus Rex's lair, so it rushed out somewhat angrily. However, the Tyrannosaurus Rex in the Black Lake had lived peacefully with Hogwarts for many years and had never attacked humans on its own initiative.

Peter was startled by the giant octopus, but he quickly recovered. Having attended Hogwarts since childhood, he was no stranger to giant octopuses; students often saw them flipping over in the water from their windows, knowing they were neutral creatures that wouldn't harm them. But with the pursuers closing in, Peter, overcome by fear, pointed his wand at the octopus's massive head and roared, "Ipalio (Impatiens Curse)!"

The Tyrannosaurus Rex's mental strength was no less than that of a human. Peter had clearly exerted all his strength, and even blood seeped from his nostrils. However, the Tyrannosaurus Rex trembled all over, and its huge eyes suddenly turned white. With a flip, more than a dozen huge tentacles and arms rushed towards Bai Lin and Black Pack.

"WTF!" Bai Lin was so scared that he lost two and a half of his souls. He never expected Peter to pull such a trick. The level 9 Tyrannosaurus Octopus could steal his soul so easily. The Tyrannosaurus Octopus didn't expect this either. Its big head was right in front of Peter, within reach, which is why it was so easily caught.

"Petrify them all!" Blake, who was a few meters behind Bai Lin, arrived just in time and cast a petrification spell on the octopus tentacle that was coiling towards Bai Lin. The tentacle immediately stiffened, and Bai Lin easily dodged it.

The other octopus tentacles were woven into a large net, with huge suckers on it that made people tremble. Even if he wasn't entangled, just being sucked by these suckers would make Bai Lin feel like he would be sucked into a big hole.

Fortunately, the mermaid's blessing made Bai Lin very agile in the water, but the Tyrannosaurus was too big. With a single suck from its huge mouth, it created a strong current, causing Bai Lin and Black to swim involuntarily into its mouth.

"Incisors as big as clubs!" Bai Lin looked at the giant octopus's mouthparts and its huge fangs, and couldn't help but think of this funny spell. Instantly, the giant octopus's fangs grew bigger and bigger, blocking the other mouthparts and blocking its big mouth.

Bai Lin kicked the enlarged fangs and swam away. Two huge tentacles came towards him. Bai Lin quickly shouted, "Shrink quickly!" He threw two shrinking spells, and the middle section of the two tentacles quickly shrank, turning into a comical shape with big ends and a small middle. Bai Lin crawled out from the gap.

Blake was still stubbornly using the petrification spell to defend against the tentacles when Bai Lin shouted, "Go deal with Peter! Just knock his wand off!"

Blake quickly obeyed and began circling outwards. The Tyrannosaurus Octopus tried to stop Blake with its tentacles, but Bai Lin aimed a "Frost Arrow" at the base of one of its tentacles!

While they were in the water, the Frost Arrow didn't fly like an arrow; instead, it froze from the tip of Bai Lin's wand to the base of the Tyrannosaurus's tentacles. Several tentacles were frozen, and the Tyrannosaurus's pursuit of Blake was immediately hampered. Two of its tentacles missed their mark, and Blake successfully escaped.

Bai Lin struggled to swim through the gaps between the numerous tentacles, slowly approaching the side of the giant octopus. If it weren't for the blessing of the mermaid, with human swimming speed alone, he would probably have already been grabbed by the tentacles and stuffed into their terrifying mouthparts.

Finally, Bai Lin froze the two tentacles blocking its path, quickly squeezed through the cracks in the ice, and broke free from the dangerous encirclement of tentacles.

Meanwhile, Blake finally spotted Peter struggling to control the Tyrannosaurus Rex, his eyes bleeding. He darted into Peter's attack range, aimed at Peter's wrist, and shouted, "Ixpariamas! (Disarm your weapon!)"
