Dr. Han inserted the key into a round hole. This obviously did not match the shape of the key. However, after inserting it, the door opened smoothly.

He turned around and looked at Chen Chu and others, but found that Chen Chu and others were staring at the door. He turned his head with some confusion and jumped back several times in fear!

"I'm about to leave."

"You...A, B!" Dr. Han was surprised and was a little amused: "Didn't you leave this morning?"

A middle-aged foreigner named A and B took out a piece of silver metal and shook it: "I tried it, but it still didn't work. I want to find someone to help me get something better."

Chen Chu and others didn't know what was going on, so they thought the bald foreigner's Chinese name was quite interesting and the Chinese was very standard. They were also curious about what he called the experiment.

Hearing this, Dr. Han frowned: "Then you move faster, we don't have much time. Originally, I had two months' budget, but... I couldn't get some things in the short term, so I can't waste time because of such simple things."

A and B nodded slightly, then looked at Chen Chu and others. He looked at him, nodded to show friendship, and left directly.

When the person left, Chen Chu immediately asked, "Who is he?"

"He is a friend of Tansley, a Russian, whose real name is Vasily Zaiyev. Not long after I knew him, he told me that his Chinese name is "A and B". As for what he does... Everything here is not a familiar field, it is all his masterpieces. Almost all the real rich people in the world will ask him to help build his own vault."

It sounded very powerful, Chen Chu asked humbly: "He did all these alone?"

"Well, so, he only knows some secrets! He won't even tell the employer."

At this time, the four of them had already entered the house, and Chen Chu began to carefully observe the layout of the villa.

It's not complicated, and it can be seen that many things have been lost, and now it seems very empty. There are some things covered with white cloth in the center of the entire first floor hall, and there is nothing else.

Walking up to the second floor, there were two roads on both sides. Dr. Han said that he would go up to the third floor room and live in whatever room Chen Chu and the others would.

"It's on the second floor, the three innermost rooms." Chen Chu said casually, then walked up: "I'll go up and take a look."

He Jun followed him up, obviously also curious. Hao Bing took two steps, but was pulled by Dr. Han: "Hao Bing, can you help me get something?"

"Let's go." Haobing nodded.

...

Upon entering the third floor, Chen Chu went directly to the garden at the end of the left corridor.

I think it's good to watch below... I'll find it very messy when I get on top! This pile of gray wood, some sand and stone.

Chen Chu stood on the edge and looked down: "It must be easy to climb up this place, right?"

"Yes." He Jun just took a look, it was very easy for him anyway.

Chen Chu looked back at the door inside the garden building, which was an ordinary wooden door. He always felt that it would not be that simple, so Chen Chu went over and tinkered. He didn't find any problems on the door, but found strange grooves on the left and right at a foot of the door. The grooves were symmetrical.

He Jun noticed Chen Chu's actions, came to the groove and reached into the groove to explore, and then knocked again: "It's metal."

Chen Chu nodded slightly, without saying a word. His eyes began to look around carefully, and then he began to fumble around the groove outwards... In the end, he didn't find anything. He lowered his head slightly, seemed to think for a moment, and then pushed the door and entered the room beside him.

There was nothing else in the room except a thick layer of gray. However, there were many footprints on the gray. Back and forth, it seemed that someone often came in. After looking around, Chen Chu found a round groove on the right side of the wall near the door. The edge of the groove was made of metal.

Taking out the key given by Dr. Han just now, Chen Chu gestured to it, and thought to himself, "It seems to be the same as the keyhole outside..." Without too much hesitation, Chen Chu inserted the key in.

I only realized that this thing doesn't need to be twisted. After inserting it, I could feel that many precise parts suddenly stick out, interspersed in the complicated grooves in the keyhole.

"Chen Chu, this is a door!" He Jun shouted outside.

Chen Chu took two steps and stretched his head out to look. He saw the metal in the grooves on both sides protruding out, and a metal door was formed on the left and right: "It's quite exquisitely made."

He Jun's hands were left and right, as if he was trying to open the door directly, but his face was covered in blue veins and did not move at all: "What mechanism did you discover inside just now?"

"It's either the mechanism, it's the keyhole of this door."

"That key in your hand?"

"Um."

"I'll take a look."

Chen Chu handed it to He Jun. He held it in his hand and looked it up and down and said, "This kind of key looks complicated, but it is actually quite easy to crack."

"That's right, but since you've used this, there should be a special reason. Go to the fourth floor to have a look."

So the two of them went up to the fourth floor again.

I went around and was mainly familiar with the layout here, not to find some secrets. The room on the fourth floor is relatively large, and it seems not for living. After returning to the second floor, I happened to see Hao Bing and Dr. Han holding something. Chen Chu saw that the bag was silver, and it seemed that there were a lot of things in it: "What are these?"

"Since you are going to live here, these are necessary." Dr. Han said with a smile.

After saying that, Chen Chu knew what was inside.

The three of them each carried one and walked into their room.

After opening the bed sheet and quilt inside the compression bag, Chen Chu quickly prepared it.

Dr. Han originally wanted to come to help, but he didn't expect that Chen Chu was so quick, so he went up and caused trouble: "Where is Dabai?"

"I don't know where to go to play." Chen Chu replied without looking back.

"You don't usually look at it, what if you lose it?" Dr. Han said with some blame.

"If I get lost, it may be able to find me back." Chen Chu replied with a smile: "Don't worry, even an ordinary cat can find the way home, you know that."

"Just so relieved?"

These are Chen Chu's experiences, and he couldn't control it: "I just looked at every room, but I didn't see any special instruments. Is there a basement or something?"

"Yes." Dr. Han nodded: "I'll take you to see. Maybe you can use some things first."

Chen Chu was very curious and went out and called He Jun who was studying whether the quilt was square or rectangular, and Hao Bing who was studying the window.

The entrance to the basement is behind the hall stairs, a very ordinary wooden door. There is a creaking sound when you push it open. Chen Chu is very confident that he can kick it open. The stairs are about twenty steps down, and there is another door below, which is quite powerful.

"Can you have some new ideas?" Chen Chu said.

"Hmm?" Dr. Han looked at Chen Chu with a daze.

"This is true in every movie." Chen Chu pointed to the password lock on the side: "Will you recognize fingerprints or pupils after opening?"

Dr. Han laughed in silence, and he didn't explain. After entering a series of passwords, he opened the dark lock. At this time, he took out a card... The light in this place was very dark, and Chen Chu couldn't see what it was. However, the card passed by and the door opened.

White light shot out from the crack of the door.

What caught my eye was the white background, and Chen Chu had the illusion of entering the hospital.

At this time, his eyes opened and he happened to see the card in Dr. Han's hand. It was transparent, with a curved thing in the middle of the card...

"What is this?" Chen Chu raised his hand and pointed to the card and asked.

"You gave it to me at the beginning."

"I gave it to you?" Chen Chuyi looked dull.

"Dabai nails are unique in the world and absolutely impossible to copy!" Dr. Han said loudly, as if he was announcing something.

Chen Chu's mouth twitched, "I cut my nails several times, but I lost the toilet." According to the principle, cats try not to cut their nails, but if Chen Chu doesn't repair Dabai's nails, it will be like a knife.

"What's the difference between Dabai's nails?" He Jun asked curiously.

Dr. Han glanced at Chen Chuyi.

"It's okay." Chen Chu said.

"There are many special strands on the big white nails, and these strands cannot be imitated. We have tried to forge them, but they all failed." Dr. Han looked excited.

"This is indeed a magical cat." Hao Bing sighed.
