"This is certainly not an accident, this is the direction that the survival instinct guides before death."

Fang Yan opened the ordinary barrage and started today's first interaction with the audience:

"Guys and beauties, what do you think?"

[Yuan Fang, what do you think? 】

[I look with my eyes] [I see with VR glasses]

[Using the basic deduction: Suppose you yourself are the person who is about to burn to death, where will you move before you die?] 】

[666, the basic deduction method 6 is not good.] 】

[We have a detective in the middle.] 】

Sometimes a person's brain is not enough, and brainstorming can only work wonders. In this interaction, Fang Yan gained an important idea: Suppose you yourself are the one who is about to burn to death?

"If I'm in a fantasy and I feel hot and on fire, I'll probably move closer to a place that feels relatively cool."

With that, Fang Yan stepped into the area that the evil key had been hinting at with an arrow step.

This time he didn't simply look at it, he got down on one knee and gently pressed the damp floor tiles with both hands.

This static action was maintained for a full twenty seconds, Fang Yan's brows furrowed, he didn't know what he was thinking, he seemed to be looking forward to it, but he couldn't wait for the desired result.

Another half a minute passed, and he turned around and shouted, "You both come here, let me touch it, it's best for Miss Qin to touch it for me." ”

[Poof! 】

[Is this tomb robbery or flirting? 】

[Shuang'er, come here, the widow wants to touch you]

[My king eats both men and women? 】

[WIFI Man: Why is it best to touch her?] Fang Yan, do you dislike me? 】

[Excuse me: Is it good to touch Captain Jin or to touch / Captain Chest?] 】

[Hahaha, touch/chest captain 666]

……

Before Fang Yan could explain the reason, the barrage was already flying all over the sky, and he was busy explaining:

"Just touch the back of your hand. Second, I wish you that your skin is too thick, and it is estimated that you can't sense the temperature difference. ”

The sentence "Your skin is too thick" made Erzhu speechless, and Qin Shuang, who had fine skin and tender meat, also cooperated, and generously stretched out his little hand.

Fang Yan held her hand delicately and said tentatively, "How is it?" Is there a little cold feeling? I think it's already below 0 degrees. ”

"-4 degrees Celsius."

Qin Shuang lifted his wrist lightly, and the bracelet showed a precise temperature value.

"And so it was. There's an ice eye deep underground. Come, start from here and open up the next floor. Fang Yan hurriedly connected the voice, "Professor, you read that right, this is indeed a wheel kiln, and the ancients were 2,000 years ahead of us to build a wheel kiln." ”

"If it's a wheel kiln, what about the chimney?" Kim San-seok throws up a key question.

"There are chimneys, but we are thinking in the wrong direction, this chimney does not go straight into the sky, but leads to the ground."

Fang Yan's answer was very shocking.

It's just that...... Those pit dad's barrage is not on the same channel at all:

[How did minus four degrees come about?] 】

[Tonight's physics homework: How did Qin Mushroom's "-4" come about? ] 】

[Online waiting, urgent! ] 】

[Tell me casually, you people are really serious. 】

[Bastard, I obviously want to touch my sister's hand, so I have to pretend to be serious and do my job. (Powder)

[This Fang Yan is so hateful] (powder)

[Yes, I learned another flirtatious move. 【Touch it with your hand, and I'll measure the temperature difference.】 】

[Capture a tapped lieutenant alive, and hope that the relevant departments will take care of it. 】

……

Fang Yan spent two minutes tapping on the slightly slightly different temperature tiles.

The audience is curious about the location he finally decided, and how he plans to dig it?

"These tiles were filled in before the ancient builders left. The Ice Eye Tunnel below is also a spectacle. ”

Fang Yan groped in the nylon tube bag behind his back with his backhand, and laughed: "If I wasn't in the live broadcast, I would have dug it up directly with a hoe and a short shovel, but isn't this time an archaeology?" It's better to give the leader a little face and keep the integrity of the tomb as much as possible. ”

Qin Shuang didn't understand what Fang Yan meant at all, until he felt out a huge suction cup.

This is not a rubber suction cup for children to play with, but a vacuum suction cup used in engineering technology.

The tray is the size of a dish, and the connection port of the suction nozzle has a fitting structure and a hose structure for the vacuum system.

As soon as this disc came out, the truth emperor immediately jumped out of the barrage:

[I know this suction cup, it's a vacuum suction cup!] 】

【Tile suction cups? 】

……

Fang Yan didn't waste time explaining, and his actions were enough to answer people's doubts.

He pressed the suction cup, lifted a brick in one go, everything was difficult at the beginning, after the first brick was taken out, it was much easier to deal with next to it, and the second wish was to lay down his hand on the side, and even pry the belt, and made six turns one after another.

The entrance of this inverted "chimney" is not a perfunctory matter of a layer of bricks, Fang Yan repeated his old trick, and used a suction cup to suck out another gap in the center of the second layer, and so on, tossing for ten minutes, and finally touched the end.

As expected, the inside of the chimney is hollow, and opening the entrance is tantamount to opening a hole in the ground.

However, although the cave was opened, the three people at the entrance of the cave did not dare to go down.

The three of them squatted in front of the entrance of the ice eye cave, and the cold air continued to rise. The viewer's perspective is the best of what it's like, like opening a freezer in the summer and condensing droplets keep appearing nearby.

"What the hell is this? A layer of fire, a layer of ice? "Erzhu is a little nonsense, "Is there still a tomb pattern of ice and fire?" ”

"I haven't heard of it anyway. I don't know what the situation is down there, but I haven't measured the depth of the chimney, so I'm worried that there is a hole in the ice underneath. ”

Fang Yan, who said this, had a headache, and he threw down the simplified version of the depth measuring instrument.

But it had been several seconds since the sensor on the end of the wire touched a hard object or liquid.

"Could it be an underground ice fountain?" A line of words lit up on Qin Shuang's bracelet.

She is extremely sensitive to things of the ice attribute, which is related to her small cultivation exercises, and her intuition tells her that there is an unknown extremely cold thing at the end of this chimney.

Extremely cold, in her cognition, requires a very low temperature to be considered extremely cold.

"It's bottoming out. Underneath is hard and unlikely to have water. Fang Yan looked at the value on the measuring instrument, and the current depth displayed was 33.3335 meters.

"About 99.99 feet." Erzhu immediately converted, "The 'long' of 'nine' and 'long' was the most respected number in ancient times. I guessed that the height of the chimney was a special number. ”

Fang Yan swung the thread of the measuring instrument and reported:

"The chimney gets narrower the way to the top, and the deepest part below is almost a meter wide. I can't tell what the probe is touching, it could be a regular hard object, it could be a stream of water that happened to hit me with a dry item, or it could be frozen underneath and it's unlikely. ”

"That'...... Go down and see? "Erzhu is eager to try.

"It's all here, it's definitely going to go down, tie the rope well, I'll take the lead, I wish you to follow, Qin Shuang will stay on it first, and pull us up if necessary."

In this line of gold, he pays attention to the heavens and the earth and enters the sea, and is proficient in everything. Occasionally, with only a rope tied around his waist, he began to dig into the ground desperately, like touching the hanging coffin on the cliff and drilling the gap in the abyss of the canyon, which was harder than the workers of the geological expedition.

The three of them had already prepared before going down to the tomb, and they all had hidden hanging rings on their heads, which was very convenient to tie ropes, and then used their claw hooks to set a few piles around the cave entrance, and then they could confidently and boldly explore down.

The initial section of the chimney is very spacious, with a diameter of five meters.

In the audience's field of vision, Yandi and WIFI Man are completely two different in-depth styles:

Erzhu cringed and hugged the rope, sliding down little by little with the help of the pulley, although the hydra shot down, but he didn't dare to look down, it was really hard for this guy, a person who was engaged in technology was forced to go up the knife mountain and go down the oil pot.

Fang Yan is a master of art and bold, his head is down, his feet are up. I didn't worry about whether the rope would suddenly break and fall headlong.

Like a fish swimming in the deep sea, with a smart body and a cheerful rhythm, it drilled down more than ten meters unconsciously.

[WIFI man is so cowardly]

[It's pitch black down here, and the Shenhuo flashlight can't shine clearly, I don't dare to look at it] (pink)

[What if a python suddenly pops up?] 【Blocked alive inside】

[Waiting for the anchor to become a turtle in the urn]

[WIFI man, do you dare to put the camera on it, I want to see Qin Mushroom Liang]

[Fang Yan practiced in the circus, right? ] 】

[The kneading technique of this aerial rope can be performed on the Spring Festival Gala]
