A day at Hogwarts

The sky was overcast, with drizzle falling in the morning, and by noon the raindrops were as big as beans.

The wind was strong, and the waves rolled up and crashed at the foot of the cliff, making a roaring sound.

There is a tall rock standing on the sea. It was once part of the cliff and now stands alone among the waves.

Three people suddenly appeared on the top of the rock. The one in the middle was holding a 406mm long magic wand. The one on the left had a mahogany sword and a sack on his back, and the one on the right was holding an old hen in his hand.

Jack pointed with his wand at the cliff opposite and asked the man on the left: "Lao Jiu, can you feel anything?"

Lao Jiu said solemnly: "It's so heavy with death, it's not just one or two."

After speaking, he turned back and patted the bottom of the linen bag behind him. A palm-sized copper bell flew out from the top of the bag. He handed it to Grindelwald, who was holding the chicken, and said, "Take this, and wait for it if there is any danger." Shake it up and we’ll be safe.”

Grindelwald took the bell and thought that this Chinese was pretty good, thinking that he would take care of himself because he was weak.

Jack's mouth twitched slightly when he saw the copper bell. He raised his wand and cast a spell towards the cliff, and a cave appeared on the cliff.

If the Weasley children were here, they would find that this cave is where Ginny was found after she ran away from home.

Jack said: "The original road has to be swam through the sea. I have opened a new road. Let's go."

After saying that, he used the flying spell on the opposite cliff and flew to the entrance of the cave.

The peach wood sword behind Lao Jiu flew up and landed at its owner's feet. Lao Jiu stepped on it and flew to the entrance of the cave.

Grindelwald walked out of the rock as usual, and the water below rose to form a staircase leading to the cave entrance.

It was cool in the cave. Everyone walked down and came to a huge cave with rock walls on all sides and stairs leading to the sea.

Jack smiled and said to Lao Jiu: "Guess where the door is."

Lao Jiu took out a compass halfway, held it in front of Jack and said, "This won't trouble me."

Grindelwald shook his head slightly. The people in the east always like to use various props for convenience, but they also ignore their own comprehensive development.

Jack saw him shaking his head and said: "Human energy is limited. Even a genius like me cannot learn all magic. They spend their energy on mastering one direction, cooperating with others or using other tools. Making up for your own shortcomings is the right direction for development.”

Grindelwald said nothing more. This kind of route dispute has lasted for hundreds of dollars and thousands of years. It cannot be explained clearly in a few words.

Jack raised his wand and used "Original Appearance". A dazzling white light lit up on the rock wall in the direction pointed by the compass pointer. This light formed an arch and then disappeared.

"That's it," Jack said to Grindelwald. "Pour the chicken blood on it."

Grindelwald carried the old hen that he had fed for several months over, holding the chicken wings with one hand, and took out the wand with the other hand and scratched the chicken's neck.

The chicken blood sprayed onto the rock wall by itself, and the rock wall glowed white again, and the arch appeared. This time it did not disappear again, revealing the gloomy doorway.

Grindelwald said to the two people who came over: "This magic is really not good. If it were me, I would have to bleed at least one person's blood."

The three of them walked into the doorway, and there was a black lake inside. The lake was faced with black glass. It was so calm that it was terrifyingly calm. You couldn't see your head forward, and you couldn't see the top of the cave when you looked up.

Jack ignored the green light in the middle of the lake and took Lao Jiu to the black lake and pointed to the bottom of the water.

Lao Jiu looked towards the lake, his expression suddenly became solemn.

He took out a yellow talisman paper from his pocket, and when his fingers crossed it, traces of vermilion appeared, and then he threw it into the air.

The talisman burned in the air and floated there, emitting a pale light and illuminating the surrounding area.

At the same time, clusters of white light also appeared at the bottom of the lake, as many as hundreds or even thousands.

Lao Jiu explained: "This is a corpse-finding talisman. It can be used to find corpses, zombies and the infernal corpses around you."

Grindelwald looked at the glowing Inferi at the bottom of the lake, shook his head and said, "What a bad taste."

He turned to Jack and asked: "With your strength, it doesn't matter how many Inferi there are, right?"

Jack replied expressionlessly: "It's not a problem that I destroyed them, but I want their relatives to see each other for the last time and be buried in peace."

Lao Jiu frowned and said, "There are too many of these Inferi. I need to make some preparations."

Jack nodded. This was what was promised at the beginning, but the "more" that Lao Jiu thought was only double digits, and now it has greatly exceeded expectations.

Lao Jiu added: "Let's take one back first and study it to see which method is best."

Retrieving an inferi was not a problem for them, and they soon retrieved a young man's inferi from the bottom of the lake.

The Inferi looked to be less than twenty years old, with black hair, sunken cheeks and eye sockets, and skin as white as lime.

As soon as the Inferi came out of the water, it ignored Jack and Lao Jiu and stretched out its slimy-looking hands towards Grindelwald.

Grindelwald looked speechless, looked at the old hen corpse in his hand, cast a spell with his wand and threw it into the air.

The Inferi was attracted by the smell of the old hen's blood. It stood under the old hen and stretched out its hands to catch it, but it always missed.

Lao Jiu took out another piece of talisman paper, drew a somewhat complicated pattern on it, and went over to slap it on the forehead of the Inferi.

The pattern on the talisman paper flashed red, and the Yin Corpse seemed to have pressed the pause button, standing there motionless, with its hands hanging down.

Lao Jiu nodded and said: "As long as it works, I'm afraid it won't be effective if it's different types."

Grindelwald watched in amazement. If he had done it himself, he would have burned it all.

He asked, "How do we get it back?"

Jack looked at him matter-of-factly.

Grindelwald's face suddenly turned as white as the Inferi: "You don't want me to carry it back, do you?"

Jack said: "You can just hold it."

Lao Jiu took out another small copper bell. The style was different from the one he gave Grindelwald just now. It was relatively simple. He shook it in front of the Inferi. The Inferi took two steps forward when the bell rang.

Grindelwald breathed a sigh of relief.

He suddenly thought of something and handed the old hen body to Lao Jiu, his face full of curiosity and expectation.

Lao Jiu smiled, took out another piece of talisman paper, drew it and pasted it on the chicken's head, and then the old hen walked out of the cave following the sound of the bell.

The group returned to the island and took the Inferi to the cave to begin research.

During dinner time, Lao Jiu gnawed on a chicken leg and said, "This kind of inferi is a little different."

Grindelwald asked curiously: "What's the difference?"

He has studied black magic for many years, and has also studied the Inferi. He just made dinner and did not participate in the research. He was curious about what was different.

Lao Jiu said while eating: "This kind of Inferi is contagious. I heard that ordinary Inferi will only eat people. Today's Inferi can turn the people it kills into the same Inferi."

"The one I brought back today has a lot of scratches and teeth marks on it. I'm afraid it was changed after being killed by other Inferi."

"This kind of Inferi must be eliminated. It will be difficult to deal with if it spreads."

Jack frowned and thought for a while, then finally sighed and said, "If there's no way to save the body, forget it."

Lao Jiu said proudly: "It's okay, I can unlock all the spells on the Inferi."

He continued: "But there are too many Inferi there, and I need some materials for casting spells."

Jack asked him: "Trouble, can we get it here?"

Lao Jiu said: "They need some black dog blood. As long as a drop drops on them after casting the spell, the spell can be unlocked."

Grindelwald asked curiously: "Can I use other blood?"

Lao Jiu replied: "The best is the blood of a boy, but the blood of a man is also fine, if you agree."

Grindelwald immediately shook his head.

Jack said to him: "After dinner, go find a black dog and come back."

Grindelwald was a little unhappy. Ordinary dogs were easy to find. There were people raising dogs in the nearby town, but there were no pure black dogs.

But so what if you don't like it, you can't beat it.

After finishing dinner and washing the dishes, he went out and came back happily within ten minutes.

"Hey, I'm so lucky. I picked up a black dog on the beach. It just fainted and didn't die."
