"Who's knocking on the door?" at 12 noon on the day Harry's evacuation was agreed. Ryan and the others had just prepared the vehicle to run in the tunnel and tried it twice, and after confirming that everything was ready, there was a sudden knock at the door.

"It should be Lupin, others don't know about our place. Hermione said as she reached for her wand and opened the door. "Hello, Professor Moody and Professor Lupin. It's a pleasure to see you all at this time. ”

"Good afternoon, Hermione. Lupin greeted him gently. Moody, on the other hand, nodded his head slightly and asked directly, "I heard that you plan to dig a hole from the bottom to evacuate Harry, how are you preparing now?"

"It's done. Hermione said and led Moody and Lupin into the living room, and Ryan saw them come in and pushed the couch forward, revealing a downward staircase.

"Alright, here's what we've done for the past three days. Ryan was the first to descend the stairs, while the others followed him. When the last person entered, Ryan pulled off a wrench on the wall, and the couch was back in place. Covering up the exit that had just been exposed.

"Well done, Ryan. Descending the spiral-shaped steps, Professor Lupin complimented him heartily. This downward passage allows a person to pass upright, and the walls and ceiling on both sides have been thoroughly hardened. There are also small recesses in the wall at intervals, and in each recess is placed a small vial with a flame for illumination.

Coming to about 15 meters underground, an iron gate blocked their way, and after pulling the other gate to unlock the door, the door opened inward, and the front of several people suddenly became spacious: in front of them appeared a rectangular basement of dozens of square meters, and on the other side of the basement was sunken down about a meter, and a square car was parked there.

The car looks about the size of a regular larger sedan, but looks more like a shrunken subway. At one end of the basement there is a deep dark tunnel. There were two small steel rails underneath the cart, which also ran down the tunnel into the distance until it was dark.

"It's a miracle that you built a subway in three days. Even Moody's, who usually maintains a serious face, looked at this small subway station with a look of surprise. "I'm sure the mystery man wouldn't have thought we could do this, by the way, where's the exit over there?"

"In the cubicle under the stairs at Aunt Harry's house, thankfully they were watching TV last night so they didn't hear us cutting the floor with a laser cutter. Ryan said, then making a gesture of please. "We can take this car and take a look at it and make a confirmation. ”

Ten minutes later, they appeared in the living room of the house they now rented. They had just taken the pocket subway directly to another station under Aunt Harry's house, and even climbed up to open the floor under the staircase compartment slightly, and heard the loud shouts of Aunt Harry and her uncle.

"With this subway, our plans can be a little more perfect. Moody took a sip of Hermione's freshly made tea. "Because I feel like the mystery of our transfer of Harry this time already knows about it, so now we have to have a better backup plan to ensure the safety of Harry this time. ”

"Indeed it should be. Ryan nodded, remembering that he had been ambushed by Voldemort's side while transferring Harry, and that Moody had died in the battle. "By the way, does anyone know the news that I'm digging the subway here?"

"Now it's just me and Lupin, Tonks and Dumbledore only know that you're digging a hole here, but not that you're building the subway to get Harry out so quickly, and of course, I'm sure there's absolutely no way the two of them can tell anyone else about it. Moody swore that Dumbledore didn't need to be said first, even Tonks was an elite Auror and knew when to keep it a secret.

"Alright, I think that's how it can be next—" Ryan told Moody and Lupin his plan. Lupin and Moody soon left the house, and half an hour later Sirius arrived on time and as planned.

"It's terrible. Sirius grumbled as soon as he entered. "Now Kreacher spends his days circling Narcissa and that little kid from the Malfoy family, treating me like air. ”

"Well, at least he'll be silent now that he can see you. It's a lot better than the scolding before. Ryan said, "By the way, Sirius, I heard Lupin say you can drive a car?"

"Absolutely. Sirius looked up proudly, but soon the look in his eyes darkened again. "I was young at the time, and I was very obsessed with Muggle transportation. So at that time, in addition to learning to drive a car, I also learned to ride a motorcycle. In addition to that, I learned to fix them. Of course, the only problem is that I don't have a driver's license. ”

"And the Weasleys, are you going to drive that flying car?" asked Hermione.

"Yes, what? Do you need me to drive that car for this operation?" Sirius asked.

"Of course not. Ryan shook his head. "The car was so old that it was hard not to get noticed on the street. I've spent a while remodeling a car before, and the performance is the same as that of the Weasleys, but it's not as spectacular, you can come and see it. If you can do it, drive that car tonight. ”

"Got it. Sirius's expression became serious, and he followed Ryan through the door to the garage. Parking in the garage was a red Fiat Pendo, a hatchback and the best-selling car in all of Europe last year. Naturally, it is also very easy to blend in with the traffic on the street without being noticed. After driving around the surrounding neighborhood twice, Ryan decided that Sirius was indeed fit for the next mission.

"Alright, you stay here now, and after we'll pick up Harry, you'll drive north, ten miles or so, and then take Harry's apparition with you. Hermione will follow you in a moment—" After returning to the garage, Ryan spoke to Sirius about his arrangements for a moment.

"Then I'll leave the rest to you. Five minutes later, after listening to Ryan's arrangement, Sirius patted Ryan on the shoulder vigorously before entering the living room in a dull manner.

For the next few hours, all three people in the room sat there in silence. Although Ryan turned on the TV, none of the three of them had much interest in glancing at the screen. It wasn't until it got dark that Ryan got up and changed his clothes and kissed Hermione goodbye, and then took Sirius through the subway to Number Four Privet Road.

Arriving at the other end of the subway, Sirius appeared a little restless, and kept pulling a silver pocket watch from his bosom, opening it and looking at it before stuffing it back into his arms.

"Sirius, we'll have to wait a little longer, so can you sit there and rest for a while now, for tonight is sure to be a very long night. Seeing Sirius start to move around the tiny subway station like a wolf in a cage in a zoo, Ryan couldn't stand the atmosphere and spoke.

"I know, I know everything. Sirius stood still and smiled wryly. "But I was just nervous. ”

"Understood. Ryan nodded. "After all, the task you take on is the most important one, so I think you better calm down and at least make sure you're at your best tonight. ”

"I know. Sirius nodded, and just as he was about to say something, Ryan's face changed and he pulled out a silver badge from his bosom. The badge was the size of a thumb, and was now flashing white and vibrating.

"Alright, it's time for us to go. Ryan crushed the small badge and walked up the spiral steps, Sirius standing nervously waiting.
