(October 14) countdown to the 77th day

Yao Xiaoyi touched the position where the water had just been poured out with her fingers, it was a little damp, and the difference between it and other areas was not very obvious. She took out the paper towel and spread it in this position, determining where the water eventually disappeared based on the traces of the water-soaked paper towel.

Spreading the paper towels one by one, Yao Xiaoyi finally came to the center of the flat land with a flashlight, touched the surroundings, and determined where the water stains finally disappeared.

"Girl, what are you?" Seeing that Yao Xiaoyi hadn't spoken, the old man spoke.

"There's something strange on the ground, you just accidentally knocked over the mineral water bottle, and most of the water came out, but the water is gone."

Yao Xiaoyi didn't explain too much, took the last paper towel, knocked on the place where the water stains disappeared, and only heard a solid muffled sound from the ground, nothing unusual.

She turned up her phone's flashlight brighter and crouched down to take a closer look.

Then, she paused, and immediately wiped the floor vigorously with a tissue.

Gradually, a palm-sized piece of wood appeared.

Yao Xiaoyi's mind moved, and he immediately thought of the wooden board on the wall of the wooden building.

Seeing this, the old man also gathered around.

"There is also such a piece of wood in the wooden building where Mr. Tang lived before his death." Yao Xiaoyi explained, continuing to wipe the wooden blocks until the soil on the wooden blocks was completely wiped off.

"There's a word on it?" The old man didn't see it very well.

"It's supposed to be letters, 26 letters in English." Yao Xiaoyi put the mobile phone close to the wooden block, and cast the light of the flashlight on the wooden block, and 26 English letters appeared.

"Old man, you are right, this place is where Mr. Tang wants me to find." As soon as the 26 letters appeared, Yao Xiaoyi understood that this piece of wood cleverly embedded in the ground must have hidden mysteries and could solve the mystery of the disappearance of the bones of Mr. Tang's wife and children, "This is a mechanism, and all the doubts should be behind the mechanism...... Old man, you little snack. ”

After that, Yao Xiaoyi found the letters V, L, E, and C on the wooden block, used his left and right hands at the same time, and touched the four letters with four fingers at the same time, and pressed them gently.

Click!

An expectant, crashing sound of metal components came from the rock face directly opposite the cliff.

The two turned their heads to look over, and the flashlights hit each other at the same time. Under the beam, a crack slowly appeared in the rock face, which had been originally solid rock. The crack is about half a meter long and about 1 meter above the ground.

But seeing that the crack was getting bigger and bigger, and finally expanded to about half a meter, there was another click, and it stopped, and there was an extra hole half a meter square in the rock wall out of thin air.

The two glanced at each other, walked to the entrance of the cave, and as soon as they approached, they were startled by an oncoming eerie aura and strange smell and took a half step back.

"Mr. Donald has no reason to harm us." Yao Xiaoyi said firmly, approached again, and looked in with the help of a flashlight, but saw a ramp slanting downward, and the light of the flashlight could not be reached.

"Old man, we need to go in and have a look. I believe it was Mr. Donald who was hinting at us to go in. Yao Xiaoyi stepped back, put on the backpack, thought about it, took off the backpack again, and put it in her hand, "I am in front, you are behind." ”

When he came to the entrance of the cave, Yao Xiaoyi put his backpack in advance, and then slowly climbed up and got into the hole.

Yao Xiaoyi turned around and helped the old man into the hole.

As soon as you enter the cave, the passage inside suddenly opens up. The passage was carved out of the solid rock, the two walls and the top were smoothed and polished, the ground was hewn with ditches on both sides for drainage, and the ground was hewn out of a ladder without hesitation.

This passage alone was not a one-day task, in other words, it was created long before the accident occurred more than forty years ago.

After a short pause, the two picked up their luggage and walked down.

I walked up the third staircase when there was a click behind me.

The two of them turned their heads in shock, but saw that the entrance to the cave was slowly closing.

A few minutes later, there was another click, and the hole closed completely.

Yao Xiaoyi squatted down to check the third step and thought of the secret room in the wooden building.

"There is a pressure sensor underneath that automatically triggers the opening and closing mechanism of the hole." Yao Xiaoyi explained.

More than ten minutes later, the two came to the end of the passage, and one turned right, but was blocked by a stone gate.

The double-leaf structure of the stone gate, about two meters high and three meters wide, seals the passage to the right tightly, and also shows that the passage to the right is much larger than the passage that has just come down.

On the stone door, a few lines of words are written with a pigment similar to cinnabar. Yao Xiaoyi approached and read it aloud with a flashlight to take care of the old man with bad eyes.

Welcome to the fateful person! Forgive my caution, you need to pass three levels before you can enter the inner chambers. Tang Ji. August 6, 1972

The handwriting was extremely sloppy, apparently done in a hurry. Yao Xiaoyi read the suicide note written by Mr. Tang to himself, and at a glance he could conclude that the words on the stone door were from Mr. Tang's hand.

But where is the key to open this stone door?

Yao Xiaoyi was confused, just like in the secret room, Mr. Tang didn't hint at all.

Turning his head to look at the old man Liu Hui, the old man also shook his head.

Yao Xiaoyi tried to push the stone door, but as expected, she didn't move. She double-checked the two doors again, trying to find a gap, only to find that the two doors were bitten together, and unless a switch was found, the stone door could only be opened by violently smashing the entire stone door.

She touched the stone door one by one with her fingers, but to no avail.

Yao Xiaoyi retreated in frustration, simply took off her backpack, and leaned against the wall in a daze.

Then she casually looked up at the entrance of the passage just now, in this confined space, they did not feel suffocated, indicating that there was enough oxygen in the passage. She remembered the eerie aura and strange smell that greeted them when the cave opened and they had just approached. There should be air to smell out, so where does the air come from?

Yao Xiaoyi thought of something, looked around, and there was nothing she wanted except for rocks or rocks.

"Old man, do you smoke?"

"No, I don't smoke. Why did the girl ask this? ”

"Well, looking for a windy place...... Oh, there it is. ”

Yao Xiaoyi said as she found the paper towel, tore the paper towel into as small pieces as possible, and then scattered it into the air, and the light fragments flew away, scattered in all directions, and then slowly fell, but when a few of the fragments floated to the end of the descending passage, they suddenly flew up.

"There's a wind there." Yao Xiaoyi shouted and hurried to the ground, but did not find the wind hole, but unexpectedly found a wooden block.

As seen on the previous two occasions, the wooden block is the size of a palm, cleverly embedded in the ground and blends in with the ground. The only difference was that this time there were two thin gaps on either side of the block, and it was through the cracks that the wind came in, and yes they didn't breathe in this closed passage.

When I looked closer, I saw that there were still 26 English letters engraved on it.

Without thinking about it, Yao Xiaoyi used both hands and touched the four letters.

Click!

The stone gate really moved, and slowly opened with the sound.
