I couldn't see the ghosts anymore, but I could still hear their footsteps.

The pointer on the compass held by the third uncle should be pointing to those ghosts. So as long as we follow the pointer, we should be able to follow those ghosts.

The third uncle obviously knew this too. He beckoned to me and Ma Tan to follow him, and he continued in the direction of the pointer.

I don't know where those ghosts will go, but I see that the third uncle's attitude is very firm.

We followed the ghosts for half an hour. Here, we have no direction, no destination, and the passage of time leaves almost no imprint on our minds due to the high level of mental tension. So there is no concept of time here either. This half hour is also my estimate.

The third uncle seemed to be very confident in the instructions of the compass, and kept walking forward.

Suddenly, the hands on the compass began to shake violently. There is no longer a clear indication of one direction.

The third uncle stopped suddenly, and I also understood that this was a reaction caused by the change in the compass losing its magnetic field. This shows that the ghosts in front of you have disappeared.

I moved forward with the candle in my hand, and after cutting through the fog, a door appeared in front of me.

I hurriedly beckoned to the third uncle, who came over to take a look, pointed to the door, and nodded.

Looks like the inside of this door should be the place we're looking for.

The third uncle put the compass away and stepped forward to try to open the door. But we soon found out that the door had no doorknob, and the whole door was bare.

I stepped forward and pushed it, and the door was shut.

The third uncle and I looked at each other, those ghosts were spirits, although they had cultivated into a semi-yin body, they could still pass through the door. We, on the other hand, can't get in at all if the door doesn't open.

I suddenly remembered that I had seen a door in that room with a tree, and that door was so strong that if I didn't know the Dharma in it, there was no way to open it. The door in front of me is the one nine times out of ten.

And there are no handles on this door, no keyholes, I really don't know how to open it.

At this moment, Ma Tan suddenly put his head up, looked at it, pointed to himself, and then pointed to the door.

What he meant was that he could open the door.

This was not our expectation, and the reason why we brought Ma Tan here was to ask him to see the strange tree, hoping to find some clues from it.

I didn't expect him to have research on this security door.

The third uncle and I looked at Ma Jian suspiciously, Ma Jian was full of confidence, rolled up his sleeves, and stepped forward with his chest straight.

Ma Tan asked me to go over and hold a candle to light him, and he reached out and touched the door panel. He touched it very carefully, and he didn't let go of any place on the door.

I touched it twice, and I was ready to touch it a third time.

The third uncle is obviously a little anxious, if he touches it like this, he can open the door? He must be wondering, Lao Ma is not joking, right?

I nodded hurriedly to the third uncle, I understand the old horse, he won't do anything that he is not sure of. Although I don't know about Ma Tan

Why would I think I could open this door, but I believe in him.

He groped the door a third time, began to measure it with his fingers again, and finally stopped in the upper right corner of the door.

He motioned for me to come over and pressed his finger down on the spot.

I did as he said and pressed the door panel. As a result, when you press it, you can feel that there is a slight bulge under that position.

It is not visible on the surface, and can only be felt by touching it with your hand.

With this discovery, I was overjoyed. Ma Tan seems to know exactly how this door works.

Ma Yan was in another place and pressed his finger up.

Immediately after, Ma Tan gestured with his fingers at me, one, two, three......

By the third time, we pressed hard together.

When we finished pressing, we heard the door rattle. From the door came the sound of reeds beating, and the solid door slowly opened.

Ma Jian breathed a sigh of relief and stepped aside.

My third uncle and I are both impressed by Ma Yan, and what this guy will know is like an endless treasure that can never be dug up.

I'd love to ask him how he got this open, but I don't dare to say much here.

When the door opened, the third uncle beckoned, and a few of us passed through the door and entered the room.

There is a familiar smell here, the smell of tree oil. I'm sure we're in that room again.

When we entered, the door magically closed again.

It's just that this time is different from last time, last time there was the light of the Five Emperors Buddha lamp, and we can see everything in it clearly.

But this time it was pitch black inside, and only the huge shadow of the ancient tree could be seen. There was also a dead silence all around, with gusts of wind blowing in the face.

The third uncle breathed a sigh of relief and asked Ma Jian in a low voice: "Old Ma Tou, how did you open this door?" ”

Ma Tan was stunned: "Can you speak?" ”

The third uncle nodded: "This room and the outside world are an isolated space. Here, it doesn't matter if you speak or not. ”

Ma Jian said: "It's strange, that door is familiar to me, it's a special security door. ”

"Special security doors?" The third uncle then asked, "How is it specially made?" How do you know? ”

"Laboratory. The security door to our school's laboratories is the same as the door here. ”

I asked, "Old Ma, I've been to your office, isn't it your lab?" There's nothing special about that. ”

Ma Jian smiled bitterly and shook his head: "What kind of laboratory is that?" That's just a small workshop of mine. The laboratory I am talking about is a confidential place of the school, and there are often confidential experiments that cannot be done for outsiders, and those who can enter the laboratory are several of our elders and the school's senior management. The security door of the laboratory is in this style. It's just that I didn't expect that even the method of opening is the same. ”

"How so? Could it be a coincidence? ”

Ma Jian shook his head: "Don't ask me. I don't know, but it's probably not a big coincidence. This kind of security door is not put into the market, it is specially customized by our school. ”

After Ma Tan's explanation, the doubts became even more serious

Much more. Ma Tan's school, the laboratory of Ben Cheng University, is the same as a door in this hotel. How can this be explained?

The third uncle understood and waved his hand at us: "Old horse, you are very good this time." Thank you in advance. ”

Ma Tan sneered: "Don't come to this set, what about the tree you are talking about?" I smelled the familiar smell of tree oil. ”

The third uncle pointed to the shadow of the tree: "It's over there, but we can't go over there now." Wait......"
