Hogwarts Summoning Guide

He waited anxiously for a few seconds, each second feeling incredibly long, but finally Zhuo Bi's name lit up in the team channel: "Captain? Captain, you're alright! That's great! We're all happy!" Zhuo Bi was so happy he was incoherent.

Lulu: "We're alright! Miss Granger activated the Diana's teleportation in time, taking us away from that area and into Lake Fagnano (a lake on Tierra del Fuego, Argentina). I... I'm sorry... the casualties were heavy, but we all successfully completed the mission!"

Bai Lin was stunned. He knew that when the deep-sea fishmen's reinforcements appeared, even with Lulu's powerful Holy Word spells, the wizard camp could not make up for the difference in numbers. Lulu ultimately chose to abandon the rescue and instead led the survivors back to the ship to retreat.

Lulu may have feelings for him, but she is clearly not a naive girl driven solely by love. Her beliefs make her a saint of the neutral order, not a benefactor whose actions are guided by kindness. On the battlefield, she will be a decisive and ruthless general, not someone who would risk the survival of her entire army to save one person.

Although Bai Lin didn't blame her, he still felt a knot in his heart, a feeling of being abandoned by Lulu, but he was unwilling to show it.

Lulu: "Miss Granger and Mr. Potter are both alright. We'll wait for you in Ushuaia! I've already sent the relevant information to the Ministries of Magic in various countries and the Muggle authorities. The Muggle army should be arriving in that area soon. What happens next can't be solved by individual heroism... You should also withdraw as soon as possible!"

Bai Lin: "I'll get there as soon as possible!"

Lulu: "Also, Miss Granger asked me to ask you, is Mr. Krum with you?"

Bai Lin: "..."

Even after closing the team channel, Bai Lin's mood remained unsettled. Although they hadn't known each other for long, he genuinely liked Durmstrang's Krum. This robust young man never spoke nonsense and always got to the point. Moreover, the story in the original book where he helped Harry save people showed everyone that although he was proficient in dark magic, he was by no means a cold-blooded dark wizard, but rather a warm-hearted man with a touch of inner beauty.

However, in the previous battle, he faced dozens of mind-controlled sharks with Qiqi. No matter how smart and agile he was, it would have been difficult for him to protect himself. But he still rushed forward without hesitation to create an opportunity for Bai Lin. Otherwise, with so many sharks chasing him, Bai Lin would have had no choice but to run for his life and would not have been able to complete the mission.

He woke up Qiqi, and the two drank some fresh water. Bai Lin wanted to try Apparition, but no matter how much he concentrated, he could only teleport less than ten meters. The dizziness and stomach discomfort after landing almost made him vomit up the fish he had eaten yesterday.

"I hope the summoning spell is still working..." Bai Lin murmured. Since the Mermaid's Blessing was upgraded from level 3 to level 6, it has added a very powerful Water Shield. This shield seems to have a strong defense against magic attacks, but it does not provide much benefit for underwater movement. In underwater combat, he needs to improve his mobility and adaptability to water even more. In addition, the fact that he loses the shield protection after Phantom Shift has also caused Bai Lin a lot of trouble.

At this moment, Bai Lin suddenly remembered that he still had three pet biscuits, which were the reward for defeating the mutated Rune-Striped Sea Serpent in Black Lake. They could increase the level of summoned creatures of level 6 or less. Because the biscuits were small, he did not put them into the system storage space, but instead casually stuffed them into his magic wallet. He touched the inner pocket of his leather armor and was glad that the wallet was still there.

Bai Lin took out a fine pet biscuit, and Qi Qi's eyes widened immediately, as if to say: Why didn't you take out the biscuit sooner? We still want to eat raw fish...

Bai Lin waved his hand and said, "This is not for human consumption..." As he spoke, he summoned the Mermaid's Blessing, and a beautiful mermaid phantom appeared in the air.

Bai Lin didn't wait for the mermaid to possess him. Instead, he tore open a cookie and handed it over. Otherwise, he really wouldn't know how to use the cookie on a non-physical summon.

Who knew it would be so magical? The mermaid's phantom was stunned for a moment, then leaned over and ate the biscuit, chewing it carefully. At the same time, the mermaid's phantom became much clearer, as if 1080P had been converted to 4K high definition.

The mermaid's face also became more human-like; her originally somewhat flat nose became more prominent, making her a stunning beauty, just like the Little Mermaid in Hans Christian Andersen's fairy tale.

Summoning spell: Mermaid's Blessing upgraded to level 7, gaining the Water Element Affinity trait.

Bai Lin was taken aback. What was this water element affinity thing? However, the mermaid's phantom quickly circled around him and Qi Qi, and both of them emitted a faint blue light.

The Water Shield's effect seemed to have changed as well, becoming a thin layer covering the outside of her body. Kiki was also surprised to find that this light blue energy was healing her wounds.

Bai Lin took out the "superior vitality potion" that Snape had given him, and he and Kiki each took a sip and drank it all in one go. As expected of a high-grade potion personally concocted by a potion master, they felt that their physical injuries, magic power, and stamina had all recovered by more than half in less than five minutes after drinking it, and they were even more invigorated.

Bai Lin eagerly plunged into the sea. As soon as he was fully submerged, he suddenly felt as if the surroundings had brightened up. The sea seemed to have become his friend, embracing him. Then, he found that his senses in the water had become more acute, and his swimming speed had increased dramatically. He felt that even deep-sea fish-men or sharks could not swim as fast as him.

Kiki jumped into the water and followed closely behind. The salty and bitter seawater seemed to have turned into sweet spring water, and she felt as if she had really become the daughter of the sea.

"Let's go out and take a look!" Bai Lin discovered that he could speak underwater, but the voice seemed to be coming from his nasal cavity.

Qiqi nodded, and the two of them swam through a winding waterway in the pool. Outside, it was indeed still the dark blue deep sea.

This ancient tortoise shell fossil was indeed very difficult to identify. Anyone who swam past it would think it was just an ordinary rock. Bai Lin silently memorized the location and released a small magical mark at the cave entrance so that he could come back if needed.

The surrounding scenery was unfamiliar, and Qiqi looked bewildered. She had been brought here by a green light that day, and it seemed that she hadn't gone very far, but Bai Lin felt that she was at least three or four kilometers away from the battlefield that day.

Three days had passed, and Zemers couldn't just stay put and wait for him to return. In the deep sea, he suddenly realized that he was completely lost and couldn't tell which way was which. Where could he find Krum's whereabouts?

Bai Lin thought for a moment and decided that he should first surface and use the constellations to determine a general direction, and then search in the southwest direction, where he should be able to find traces of Zemers' passage.

As he was pondering, Qiqi swam over and tugged at his sleeve. He turned around and saw Qiqi pointing to the upper side. Bai Lin looked up and followed her finger. A dark object was approaching from a distance, several tens of meters long. It was a black submarine marked "SS4, Grampus." Although Bai Lin didn't know much about modern weaponry, he could roughly tell that it was a submarine belonging to the American Muggle military.

"We're following it; it's probably tracking Zemers based on the signals from the positioning device!" Bai Lin whispered.

Now, besides following it, there really wasn't any other good option. Of course, Kiki wouldn't object. The two of them clung to the seabed, hundreds of meters apart, hanging behind the submarine. The Muggle soldiers in the submarine would never have imagined that they were being followed in the deep sea, hundreds of meters below the surface.

With the blessing of the mermaid who is affinity with the water element, they can swim very easily. It seems that as long as they swing their feet, the seawater will push them forward on its own. Even when following this rather advanced Muggle submarine, they feel at ease.

The submarine moved forward at a leisurely pace. Before he knew it, Bai Lin had been swimming with it for two hours. No matter how relaxed he was, he felt the strain. They had already traveled at least sixty or seventy kilometers. Bai Lin gritted his teeth. He knew that following like this would eventually kill him. He waved to Qi Qi and decided to go all out. He found a rather tricky angle and swam directly towards the submarine at high speed.

Whether it was due to the mermaid's blessing or not, the submarine did not detect the approach of the two living people at all. The two grabbed the low railing on the top of the submarine and hitched a ride.

Qiqi swallowed hard. She was exhausted. She had lost a lot of blood from her wounds and had only eaten some raw fish and meat in the past few days, which was not enough to sustain her energy today. Clinging to the submarine made things much easier.

Without anyone noticing, they advanced another ten kilometers or so. The submarine's speed noticeably slowed down. Bai Lin peeked out and, although he didn't see the huge fossil shell of Serenas, he was astonished to see that this place resembled a graveyard of ships, airplanes, and submarines. At a glance, there were at least seven or eight warships, three or four submarines, and the wreckage of some helicopters and small planes, all sunk in this area. They all seemed to have collided and were severely damaged. In some of the damaged cabins, there were also many human corpses.

"This all happened in the last few days! My God!" Bai Lin couldn't help but mutter. Muggles must have sent a lot of reconnaissance fleets, but for some reason, they all failed miserably here.

Even more terrified than they were were the soldiers in the submarine beneath them, but in the end, the commander decided to record the location of the sunken ship and continue onward; salvaging the ship was not their mission.

The submarine continued forward, but Bai Lin had an ominous premonition. As it turned out, Bai Lin's feeling was very accurate. After traveling about ten kilometers further, Bai Lin discovered something unusual ahead. A group of black dots seemed to have noticed the submarine's approach and emerged from a rocky mountain on the seabed.

"They're controlled deep-sea fish-men!" Bai Lin whispered.

If the soldiers or instruments on the submarine were not blind, they would have noticed the presence of some kind of enemy force ahead. Under normal circumstances, submarines cruising on the seabed would not fire their cannons unnecessarily. However, having just passed through the "graveyard" of warships, the submarine commander was clearly on high alert. Upon spotting the unidentified object ahead, he immediately slowed down and launched a volley of torpedoes.

This was Bai Lin's first time seeing a submarine launch a torpedo. In the movies he had seen torpedoes, they were powerful but slow. But seeing it with his own eyes today, he realized how misleading the movies had been. In fact, during the Cold War, Muggles had already developed torpedoes with a speed of 370 kilometers per hour. That speed might not be that fast in the air, but underwater, it was almost impossible to hit anything, it was incredibly fast.

The torpedo flew swiftly across the seabed and charged towards the group of deep-sea fishmen. The controlled fishmen did not sit idly by and wait for their deaths. Several fishmen holding staffs rushed out of the group and instantly opened a magical shield with light yellow light flowing through it.

"Damn, they can use magic!" Bai Lin cursed inwardly, at the same time understanding why the merman reinforcements had so easily defeated Lulu's team that day, leaving them with no choice but to teleport away.

The torpedo exploded violently in front of the magic shield, and the shockwave could be felt even by Bai Lin, who was several kilometers away. But after the flames and mud dissipated, Bai Lin discovered that only two or three mermaids seemed to have been killed. Their main force continued to charge forward without hesitation. At the same time, another group of dark figures appeared from another direction, which seemed to be the group of controlled sharks.

The submarine seemed to sense something was wrong. They were isolated and helpless. If the torpedoes were ineffective, the submarine didn't have many other ways to attack on the seabed. After launching another volley of torpedoes, it actually tried to turn around and run away.

"WTF! Why are you being so cowardly?" Bai Lin cursed when he realized the submarine was trying to turn around.

However, the submarine didn't care what Bai Lin thought. At this moment, the submarine commander seemed to understand why so many warships had sunk together. This group of unknown enemies must have some powerful attack capabilities. So, between throwing his life away and sticking to the mission, he decisively chose the latter.

The second volley of torpedoes also had limited effect on the mermaids. The octopus-faced mermaids easily dodged half of the torpedoes, while the other half were successfully neutralized by the merman mage. Only two unlucky ones were killed, turning into a pile of minced meat and blood.

A short while later, the submarine turned its bow and headed north. As it fled, it threw a string of black, football-sized objects from not far from Bai Lin. Without a doubt, they were mines. The submarine seemed to be using these things to hinder the enemy and buy itself some time to escape.

However, the commander's wishful thinking did not work out. With the merfolk charging with all their might, the submarine and the enemy were less than a kilometer apart. The merfolk mages raised their staffs and launched light blue missiles, just like in the battle with the wizard that day.

"FK!" Bai Lin cursed, quickly pulling Qi Qi off the submarine and dashing towards the seabed, hoping to find some seaweed or something to hide in.

Following the updates has never been so enjoyable.
