This gate appears on the side of Lhotse Peak, and according to the proportions, the height of this gate should be at least a few tens of meters high and at least a dozen meters wide.

Moreover, judging from the aerial photos, there seems to be a faint humanoid pattern on the door.

"This, this," I looked at the picture and was speechless for a long time.

But Qu Fattou said on the side.

"Huh? Why do you have playing cards on this picture? Tiger eggs, can you recognize this one? ”

Not to mention, the rectangular door with a human shape on top does look like a playing card embedded in the vast snow-capped mountains.

Chen Hudan stared at the photo for a long time, and said hesitantly.

"I can't see it clearly, I look like a square old K."

The faint human figure on the door does look a lot like the old man on the block K.

It's just that I know very well in my heart that this is not a playing card, where can there be such a big playing card, just this length, width and height, that area must be at least 100 meters

"Is this door still in place?"

I stared at the aerial photographs and asked Professor Chen.

Just from the aerial photos, it is not clear what the door is made of.

If you look at it from the outside, the huge gate is about the same color as the rocks on the mountain.

If it weren't for the angular shape of the door frame and the faint humanoid pattern on it, it would have been easy to ignore it as an exposed rock.

"I guess it's still where I am," Professor Chen replied, but the expression on his face looked solemn.

"Should?"

I asked in a daze.

"Then there were several big avalanches on the mountain, and the sudden door was completely buried in the snow."

Professor Chan explained.

"And you should hear this again," Professor Chan said, taking a small tape recorder from his assistant and placing it on the table.

"At the time of the avalanche, the communication equipment on the plane was interfered with by a strong external signal, and the crew did not hear the content of the signal because of the emergency situation on the plane at that time and the noise in the signal was very strong. However, the receiver on board the plane recorded the signal, and then after professional audio stripping, such a recording was obtained. ”

After speaking, Professor Chen reached out and pressed the play button of the tape recorder.

The conference room suddenly became unusually quiet, and everyone was afraid to come out, you look at me, I look at you.

At this point, everyone pricked up their ears to listen to the sound coming from the small tape recorder.

There was no unusual sound coming out of the recorder at first, just a long hissing sound.

It was the sound of the empty belt passing by.

I was so anxious to get Professor Chan to pour the tape backwards and listen to the key parts.

Suddenly, a faint sound came from the tape recorder, sounding like a "bang" when something was broken.

Because it was very quiet, the faint sound sounded very clear.

After that faint sound, there was no sound coming out of the recorder for a long time.

"That's it?" Qu Fattou glared at Professor Chen and asked.

"Together, we listened to the movement of a sullen fart who didn't know who was going to do it."

Before Qu Fattou finished speaking, Professor Chen waved his hand and motioned for him to shut up quickly.

Qu Fattou was still a little unhappy, and was about to open his mouth to talk to Professor Chen, when he suddenly heard a strange sound from the tape recorder.

This time the sound was much louder than the faint "whoosh" sound before.

It was a series of "clucking" sounds, sounding like the sound of an old hen with pharyngitis.

"What the fuck is going on? Surprised? ”

Qu Fattou was startled by the sudden "gurgling" sound, and couldn't help but scold.

"I feel like an old hen!" As soon as Qu Fattou's voice fell, he heard Chen Hudan on the side answer with a serious face.

"It's definitely right, I don't know which old hen can't lay eggs, and she screams."

I hurriedly pulled Chen Hudan's picket aside, so that he would not continue to be embarrassed.

"Professor Chen, what was the sound in that just now? Do you guys have any conclusions? ”

I pulled Chen Hu's egg steak aside and asked Professor Chen about it.

Professor Chen had been in possession of the tape for several days, and he should have known what those strange sounds were coming from.

However, Professor Chan's answer was quite unexpected.

"I only got my hands on this recording today, and I've only listened to it a few times after removing the irrelevant noises, and I don't understand exactly what the sounds are coming from. Because of this, I hurriedly brought it over to you to listen, after all, the person we are looking for is very familiar with you, could this voice be the contact code sent by Xi Jing to you?"

When Professor Chen said this, I shook my head with a wry smile.

Can he imagine this movement as a contact code?

"Wow" "Gurgle"

It's another bottle smashing and a hen crowing, whose contact code will be like this

Since Professor Chen didn't know what those sounds were coming from, there was no choice but to ask Professor Chen to rewind the tape again, and everyone listened carefully from the beginning to see if there were any other movements that could be understood.

However, after listening to it a few more times, we only heard those "whoops" and "gurgles" in the tape recorder.

Other than that, no other unusual sounds appeared.

At this moment, Bai Yi, who had been sitting on the sofa in the corner since he led us into the house, suddenly stepped forward without speaking.

She walked up to Professor Chen and spoke.

"Dad, you just let people strip the noise from this recording, and haven't done anything else?"

"Nope." Professor Chen glanced at Bai Yi and replied, and when he was done, he didn't forget to touch Bai Yi's head lovingly.

After listening to Professor Chen's answer, the corners of Bai Yi's mouth twitched.

I saw that she reached out and picked up the small tape recorder on the table, took out the tape inside, looked at it, and spoke.

"Give me half an hour." As soon as he finished speaking, Bai Yi took the tape he took out and turned around and walked out of the door of the conference room.

Bai Yi didn't say what she was doing with the tape, and we didn't ask her about it, maybe she had other ways to decipher those strange sounds.

After Bai Yi left, Professor Chen and I studied the aerial photos again, and Qu Fattou and Chen Hudan also insisted that the rectangle that appeared on the snowy mountain was a playing card square K, but it was just a little big

Professor Chen said that the huge door that appeared on the snow-capped mountain reminded him of the same huge stone door he had seen in the cave on the cliff face decades ago.

It was through the explosion under the huge stone door that Professor Chen had the thrilling experience of decades ago
