Mastering Lightning from Hogwarts

After confirming that ‘Shunfeng’ understood completely, Anduun sorted the letters and placed them on his desk. Then, he cast a Disillusionment Charm on himself again, climbed out the window, and disappeared into the night.

Perhaps because the magical world had only just returned to a peaceful period, Diagon Alley was quite calm at night. Apart from the occasional wizard walking in the alleys, there were hardly any other people, and most of the shops on both sides of the street had closed early.

The invisible Anduun quietly floated a foot above the ground, heading towards the house where the five Death Eaters were hiding. At this time, the magical coffee shop opposite the house and the beauty potion shop next door were both closed, and Emmeline Vance, who had been monitoring the area, had also disappeared without a trace.

Unsure whether the Aurors had gone off duty or were hiding nearby to continue monitoring, Anduun cautiously circled the house, searching for a long time, eliminating several suitable monitoring locations before feeling relieved.

After confirming that no one was around, he summoned a raven, just like he had in the morning, and flew it to the windowsill on the third floor to observe.

Of the five guest rooms, four had their curtains drawn and the lights turned off, making it impossible to see anything. The bedroom without curtains still had a faint light on. Inside was Yaxley, sitting at the desk by the light of the oil lamp, folding a letter and stuffing it into an envelope.

After he finished everything, he stretched wearily, took off his coat and shoes, extinguished the lamp, and went to sleep without changing clothes. After lying on the bed, he took out his wand and pointed it at the window, controlling the curtains to slowly close.

“Judging from Yaxley's state, they must be sleeping fully armed, preparing to escape as soon as there's a situation. They're well prepared.” Anduun nodded thoughtfully, still under the Disillusionment Charm, waiting quietly in the narrow alley beside the house.

In the silent night, Anduun waited for another half an hour, calculating that these guys should be asleep. He then used the Levitation Charm to slowly fly to the roof of the house and land.

Then, following the same pattern, he summoned another raven to enter the third floor through the chimney to check the situation, while Raven One remained on the windowsill outside the house, on guard, so that he could react quickly to any movement inside the room.

Raven Two entered the third floor and looked up, using the moonlight to see that the Sneakoscope he had seen in the morning had been moved to the third floor. However, at this time, the Sneakoscope did not react to the little raven in a shared vision state.

Raven Two strolled around the third floor, not triggering any alarms. After confirming it was safe, Anduun controlled it to return to the roof.

“Very good, it seems the night's security mode hasn't changed. Now comes the test of my operating skills.” Anduun took a deep breath and muttered.

Then, Anduun carefully began to take things out of his pouch, starting with a large metal bottle that looked like a medical oxygen tank.

Then there was a large bundle of various sizes of plastic hoses. He used magic to control these items to float quietly in the air, and then began the splicing work. He first installed a thick industrial plastic tube on the gas cylinder, and installed a splitter on the other end, and then slowly extended the rubber tube from the chimney.

Immediately afterwards, Anduun summoned several ravens, either holding or grabbing several bundles of long thin tubes, and also flew into the third floor from the chimney.

After arriving on the third floor, these ravens became busy.

Two of the ravens adjusted the position of the thick tube, slowly pulling it out of the fireplace, while the other ravens installed the thin tubes to the splitter. Because the hoses were connected with metal nuts, these little ravens had to laboriously tighten the nuts one by one with their beaks.

This operation left Anduun covered in sweat. He had to simultaneously control several ravens to operate, and he had to be quiet and not make any noise. When all this was ready, he couldn't help but breathe a sigh of relief.

After the tools were ready, he controlled the ravens to hold one end of the long thin tubes and come to the doors of each room, then slowly extended the thin tubes through the door seams. He operated this step very carefully. Because he was afraid of touching the door and triggering an alarm, he did it one room at a time.

After doing all this, Anduun opened the valve of the gas cylinder next to him, and the gas inside quickly diffused into the bedrooms of several people through the main pipe, splitter, and thin pipes.

“A 3% concentration of ether inhaled at more than 2 milliliters will cause coma. According to the area of their rooms, in theory, it will only take three minutes to make them all lose consciousness. To be on the safe side, let's wait four minutes, but we can't wait too long. Too high a concentration may directly lead to death. I hope none of them have heart disease, otherwise they can only blame themselves for being unlucky.” Anduun took out a pocket watch to check the time, and muttered in his heart.

When he was investigating the layout of the house, he found that all the rooms seemed to have been renovated, probably to accommodate so many people, five rooms temporarily spliced together with magic. Each room was about the same size, and the doors were not very close to the door frame. The gap under the door was larger than normal, and the windows were tightly closed, which made him think of using ether, such an anesthetic liquid, to knock down these guys.

However, low concentrations of ether can be used as an anesthetic in medicine, but it is a very terrible poison if used indiscriminately. Although it is a liquid in its normal state, it is extremely volatile, and it can easily cause lung burns when inhaled. It is also flammable and explosive, and is considered a very dangerous industrial material. He searched for a long time and only found some low concentrations of ether.

Earlier, he went to a nearby chemical warehouse and finally gathered all the equipment. It's really convenient to steal things with magic, invisibility, magical door opening, and putting things into the space bag are very simple, and the more difficult thing is finding the materials he needs.

Four minutes passed, and Anduun, who had accurately timed it, quickly closed the valve, and then controlled the little raven still inside the house to gently peck at the door, triggering the warning magic on the door to test the reaction of these Death Eaters.

After repeated attempts, there was no movement in the room, it seemed to be successful.

Anduun was overjoyed when he saw this, and quickly disassembled and put away the gas cylinder, then put on a gas mask for himself. He had to be careful about this poisonous gas himself.
