Hogwarts Summoning Guide

Looking at the scattered mines deployed on both sides of the submarine, these things might be somewhat useful against ships and submarines, but against magical mermaids, they were less effective than a heavy machine gun. Just as Bai Lin was worrying about the submarine, Qi Qi tugged at him and pointed to the other side, saying, "That's Krum."

Bai Lin looked closely and saw that among the group of sharks rushing towards them was a much smaller shark, only about three meters long. Who else could it be but Krum?

At such a distance, the mermaids' blue magic missiles weren't very accurate, but a few still managed to hit the submarine's stern by sheer luck. The submarine didn't have any magic shields; it relied entirely on its metal hull to withstand the damage. The missiles exploded at the stern, inevitably causing some damage to the submarine. However, its armor was thick enough that it wouldn't be instantly destroyed by a few magic missiles.

But Bai Lin could already foresee its fate. Submarines are undoubtedly top-notch killers against surface ships, especially when the opponent is much larger than itself. However, they are somewhat inadequate against agile sea creatures like fishmen. It's only a matter of time before ants overwhelm an elephant.

A submarine carries at least fifty or sixty crew members. Even if they are American soldiers who have nothing to do with him, Bai Lin cannot stand by and watch them die. He glanced at the shark swarm on the other side, gritted his teeth, and pointed to the rear of the submarine, saying, "Frost Arrow!"

A ball of icy energy condensed at his fingertips and flew out like an arrow in the blink of an eye, instantly forming an irregularly shaped ice wall at the stern of the submarine. The magic missile that was fired again crashed into the ice wall and exploded.

Releasing ice-attribute magic in icy seawater greatly enhances its power, but it also has significant side effects. For example, in the air, an ice arrow simply flies by in the shape of an arrow without leaving any trace, but in the seawater, it freezes the seawater along its path, forming a clear trajectory.

Although the ice wall was very effective, Bai Lin had clearly exposed himself. The officers and soldiers in the submarine were pleasantly surprised to find that reinforcements had appeared out of nowhere and helped them block the monsters' attack. However, they had no concept of international friendship, and the commander roared, "Full speed retreat! Full speed retreat!"

Seeing the submarine at full power, stirring up a huge wave, Bai Lin was speechless. How could they have no fighting spirit at all? This is nothing! If they saw Zemurus, they would be scared to death on the spot!

Seeing the submarine retreating on one side, and the fishmen and shark swarm on the other side clearly unable to catch it and only going to vent their anger on him, Bai Lin made a decisive move, pointing at the sharks and saying, "Catch Krum!"

Qiqi didn't question Bai Lin's judgment. She plunged out of the seaweed on the seabed and headed towards the shark swarm, while Bai Lin followed closely behind, continuously shooting icy arrows in the direction the mermaids were coming from.

Ice arrows shot out like meteors. Although their range was short, they created massive ice walls, like miniature villas, wherever they went. From the mermaids' perspective, the huge ice blocks not only blocked their magical missiles but also obstructed their vision.

Using ice magic as cover, the two successfully approached the shark swarm charging from the other side. The sharks had bloodshot eyes and their gaping fangs were covered with fragments of Muggle soldiers' uniforms. They were coming on strong. Although Kiki and Krum had killed many sharks in the previous days, their numbers had increased today.

It seems that while attacking Serenas, Gracchus's mind was trapped outside Serenas's mental palace, and his physical whereabouts were unknown. However, his mind magic and the octopus eggs he released continued to influence and infect the creatures around him.

A tiger shark of considerable size was the first to charge, its layers of sharp teeth sending chills down one's spine. Bai Lin felt that if it took one bite, it would probably be up to the waist. But Qi Qi still charged forward without fear. Although the Water Shield gave Qi Qi a strong boost, Bai Lin still admired her courage.

Kiki, resembling a swordfish with a spindle-shaped body, suddenly pulled herself up a meter high when she was less than five meters from the tiger shark, charging towards the shark's head.

Although the tiger shark was mind-controlled, it hadn't turned it into a fool. Its predatory instincts made it twist its head and bite at Kiki's legs. Bai Lin, who was following closely behind, couldn't help but feel sorry for Kiki, but he chose to trust her. He saw another hammerhead shark adjust its angle and aim at Kiki's upper body, preparing to fight the tiger shark for the food and share the delicious meal.

Kiki suddenly shrank into a ball, then swiftly stomped heavily on the shark's "nose" with her magical mechanical leg, instantly performing a spin. A dagger appeared in her hand, which she plunged into the tiger shark's left eye. Although the scimitar wasn't in her hand, how could a qualified assassin go to battle with only one weapon?

As soon as Qiqi rolled over, a dagger appeared in her left hand again. She slashed a gash more than a foot long in the tiger shark's gills, and blood gushed out immediately.

The hammerhead shark behind the tiger shark charged forward, about to swallow Kiki's head whole. At the critical moment, an icy arrow struck the hammerhead shark's mouth, instantly filling its massive jaws with ice. It could only watch helplessly as Kiki swam past it.

Bai Lin wasn't unwilling to be at the forefront, but he needed to locate Krum as quickly as possible. Sure enough, although his size was far smaller than the surrounding sharks, the wounded Krum still "bravely" charged to the front of the shark group, and Bai Lin quickly spotted him.

"Don't linger!" Bai Lin shouted. In the chaotic sea, he didn't know if Qi Qi could hear him. The tiger shark's blood and the churning water made the surroundings murky. At this moment, the newly acquired water element affinity once again played a super-strong role. Bai Lin's vision here was even more acute than these sea beasts. He and Qi Qi slipped smoothly out of the mouths of several sharks that pounced on them. Qi Qi didn't forget to give these big guys a few scratches.

Although a small dagger cannot kill these giants that are often six or seven meters long, the blood will mislead other sharks. Instinct will cause some sharks to abandon their target and bite their wounded brethren first.

Krum, mingling among the sharks, lunged at Bai Lin with a bite. Bai Lin thought to himself: Dude, this is the one I've been waiting for!

In this chaotic state, Bai Lin did not choose to use ray-type spells such as the Stunning Curse to subdue Krum. Instead, after narrowly dodging his fangs, he summoned Orgrim's arm and grabbed Krum's fish tail. Qi Qi took the opportunity to flip over and climb onto Krum's back again, tightly gripping his dorsal fin.

Just then, the parasitized deep-sea fishmen rushed to the area blocked by Bai Lin's ice. The strongest fishman broke out from the group, seemingly the leader of the deep-sea fishmen. However, his head was also parasitized by the octopus monster, and dozens of disgusting eyeballs grew on the octopus's head.

He seemed extremely angry, and the three-meter-long harpoon in his hand suddenly emitted a dazzling silver light. Then, he unleashed a sword aura similar to that in Eastern fantasy novels.

A crescent-shaped "sword aura" sliced ​​through a large chunk of butter like a red-hot cleaver. A small ice block, about the size of a hut, hovering in front of it, was cleaved open by the "sword aura," creating a passage more than two meters wide. The ice block slowly pushed aside, and the merman leader, yelling, was the first to rush through. With that kind of power, it was definitely the work of an elite member of the Hatas Order.

Back then, Bai Lin led the entire team to painstakingly kill Asatel. Now, only Bai Lin and Qi Qi, still injured, remain. Bai Lin had already seen his move to cleave through the ice barrier and dared not confront the fishman leader head-on. He flipped over and sat behind Qi Qi. No matter how frantically Krum twisted, he activated his Phantom Shift, targeting the Turtle Shell Cave dozens of kilometers away.

Bai Lin planned to teleport to the cave and then knock Krum unconscious to help him recover from mind control. However, whether it was because Bai Lin's magic or spirit had not fully recovered, or because Krum did not obediently accept the teleportation, when Bai Lin's vision swirled and he opened his eyes again, they were not teleported to the Turtle Shell Cave. Instead, it seemed that they were teleported in the opposite direction, dozens of kilometers to the west, and Serenas's huge fossil shell appeared before them once again.

The giant conch shell rested quietly against an underwater mountain range, but Zemurus was nowhere to be seen. However, Bai Lin quickly spotted the tips of some tentacles that were faintly visible on the other side, indicating that Zemurus must be resting inside the conch shell.

"Stun him!" Bai Lin gritted his teeth and cast a stun spell directly on Krum's head. Krum was immediately stunned by the red magical energy. However, this was the deep sea, and even a shark that was stunned would suffocate due to lack of oxygen. Bai Lin quickly cast a mermaid's blessing on him as well.

The two people and the fish certainly didn't dare to rush over and cause trouble for Zemers. Bai Lin made a shushing gesture, pulled Qi Qi and Krum down to the seabed, and wanted to find a dark place to hide first, wait for his mental power to recover, and then use Apparition again to see if he could reach the nearest land. He was simply too tired of being underwater.

However, at that moment, something strange happened on the sea surface above. Dozens of black dots seemed to be dropped from the sky above the sea and sank straight down to the seabed. They were clearly depth charges.

The depth charges were as big as motorcycles, with a small spiral structure at the rear to ensure they fell vertically. They rained down like death knells upon Serenas and the surrounding seabed. With such large wooden buoys, it would have been difficult to miss, but the depth charges still covered an area of ​​nearly one square kilometer, likely a blanket strike aimed at wiping out Zemurs and the parasitic mermaids in one fell swoop.

Bai Lin quickly pulled Qi Qi and the unconscious Krum back. The area they were in was also within the attack range of the depth charge. However, as they retreated, they saw a dome-like protective shield appear above Serenas' fossil shell. It was comparable to the protective magic array of Hogwarts, magnificent and spectacular.

The depth charges landed on the dome and exploded instantly, illuminating the deep sea with golden flames. Then, a violent explosion and tremor came from the dome, but it did not destroy the dome. Then, a second, a third... With the explosions, countless mermaids and other creatures emerged from all parts of Serenas's shell. They stared blankly upwards, watching the bombs explode like fireworks in the sky, bursting into various shapes of light.

Bai Lin watched the bomb falling from above, dodging it while simultaneously firing an ice arrow. A massive block of ice formed in the water, and the depth charge struck the ice, exploding instantly.

The explosion had a radius of 30 meters, but the shockwave it generated could reach 300 to 400 meters away. Bai Lin felt as if he had been shoved hard by the shockwave, and the two of them and the fish crashed heavily onto the rocks on the seabed. The ice blocks created by the ice arrow did not stop the depth charge from exploding, but they did effectively block the shrapnel from flying in all directions. Bai Lin rubbed his head, thankfully he was not seriously injured.

Looking up, they saw that the dome above Serenas had been attacked by at least forty or fifty bombs. Finally, in a flash, the shield ran out of energy, and depth charges began to fall on Serenas's shell, instantly blasting a large crater and revealing a dark hole. The surrounding merfolk had no time to dodge, and even if they were not killed by shrapnel, the violent shock would shatter their body tissues and internal organs into pieces.

A deafening roar came from Serenas's shell, followed by a massive, dark shadow that blotted out the sky. At that moment, Bai Lin felt a chill run down his spine.

This is Zemurus' true form, a giant octopus the size of a football field, with more than ten enormous tentacles, each nearly two hundred meters long, stretching out like a super-giant umbrella that obscures the sky over the entire sea area.

Completely disregarding the lives of the fishmen and the controlled creatures, it stretched out its tentacles, creating a massive vortex beneath its body that indiscriminately sucked countless creatures into the black hole at the base of its tentacles, like an abyss.

Its body is covered with all sorts of disgusting spots and strange patterns in black, brown, and tan. Its entire head is covered with layers of deposited metabolic tissue, but countless large and small eyeballs almost seem to be popping out of its body. Even the bravest warrior would be terrified at the sight of this appearance.
