The craft of saltpeter ice making has been widely spread in the Tang Dynasty and has become a mature industry.

Therefore, it was not much difficult for the craftsmen of the time to arrange such an "extremely cold secret room" here.

The main thing is the excitation mechanism of this trap, which needs to be laid out well.

Now that the principle of the mechanism has been found, all that remains is to find the mechanism of operation.

According to Lin Yi's inference, the periphery of this stone chamber must have been made of rammed earth rich in potassium nitrate, as long as the surrounding moisture rises, such as today's large-scale rainy weather, coupled with the moisture carried by the three of them themselves, it can cause a saltpeter reaction.

Not only that, but in order to be able to reduce the temperature of the stone chamber to below zero in the fastest possible time, and to prevent the use of saltpeter from exceeding its output, there must be some mechanism behind the stone wall that controls the flow of water.

This stone chamber is like a flat boat floating in a pool, and if the weight of the boat increases, it means that someone has entered the stone chamber.

At this time, the water level outside will overflow and react with saltpeter.

The specific manifestation is the "statue of the Heavenly King" on the four walls.

Their most basic role must be to deter tomb robbers.

Secondly, with the appearance of the four "statues of the Heavenly King" in turn, that is, the low temperature created by the reaction of the surrounding saltpeter and water, completely envelops the timetable of the entire stone chamber.

When all four Heavenly Kings appear, the trap here will be completely formed.

Is that "fan" just a reference to this trap mechanic, but not a way out?

On the other side, Wang Qiang was still panting and running laps with Qian Sheng on his back, shouting Qian Sheng's name tremblingly, telling him not to fall asleep again.

In fact, he has now reached the limit of his physical strength, and the soles of his feet are as heavy as lead.

There was a layer of frost on his eyebrows, beard and eyelashes, plus he was carrying Qian Sheng on his back and hunched over, looking like an old man.

Passing by Lin Yi's side, he looked up:

"Lao Lin, have you found a way out?"

Lin Yi frowned and shook his head at him.

Wang Qiang let out a long sigh and continued to carry Qian Sheng on his back and began to circle around.

Lin Yi was also anxious in his heart, and couldn't help but scold: Before his mother came, he didn't say that he had to take the math, physics and chemistry test for tomb robbery!

After scolding, he slammed his fist into the wall, and the ice on the wall stabbed into his fingers.

His hands were already frozen, and there was no pain, but there was a blood stain on the wall.

Netizens in the live broadcast room have begun to feel extremely anxious about their situation.

In the conference room of the county public security bureau, Team Liu's hearts also rose to their throats.

But the heavy rain in the mountains is pouring down, and if it continues like this, they will have to go to the front line to fight the flood later, and they can't take care of Lin Yi and their brothers at all.

Of course, there will always be people who speak cool words.

It's nothing more than that Lin Yi and they are holding it up, and they will definitely turn over this time.

At this moment, the three Feng Shui masters from Xiangjiang who lived in Zhouyuan Hotel were also looking at the mobile phone screen, leisurely eating fruits, and watching Lin Yi's jokes.

"Lost! Fight the streets, mainland boy, grab business with us, this time see who can save you. ”

A lean young man sneered at the screen of his phone as he sent a variety of rhythmic barrages.

"Shigong also said let's keep an eye on this guy, he has a good hand, I don't think that's it. Now these northern feng shui masters are a bunch of waste, so they can only hold a compass and look at the yellow calendar. ”

Another young man with eyes immediately joined him and teased.

The older middle-aged man on the couch, with a cigar between his fingertips, puffed clouds and mist, and it took a long time for him to express his opinion.

"Shigong must have a reason when he says this.

The decline of the Northern School has certain historical limitations, and many high-ranking people have either retired or disappeared completely.

Many of these methods and books have been lost.

I think this guy's methods and vision are indeed not simple, and he combines the strengths of hundreds of schools.

We are worthy of the 'north-south dispute', our southern faction now has the upper hand, if he is allowed to break into the name, our southern faction will have a hard time in the future. ”

His accent is not like that of the Cantonese region, but a bit of southwestern official dialect.

"We just haven't dealt with the mainland's public security, and if we want to say that this land, we still discovered it first.

Since he likes this business so much, let's just give it to him and see if he has the life to make this money. ”

The thin man held his mobile phone with a "melon-eating" expression.

The eyes walked to the middle-aged man's side, poured him tea, and asked respectfully:

"Big guy, do you think he will be able to come out alive this time?"

The middle-aged man's gaze paused.

Then he shook his head.

"If it's a feng shui bureau here, then he might still have a life. Now that this place is full of deadly mechanisms, what's the use of finding those 'Dark Eight Immortals'?

Even the reincarnation of the Eight Immortals can't save him now! ”

"So what are we going to do?"

"Of course, after they hang up, I will recite the death mantra for them a few more times!"

After speaking, the three of them laughed and each picked up a teacup, touched each other, and drank it all.

At the same time, in a deep house compound in Shangjing, two old men, sitting under the grape trellis in the courtyard, actually had a mobile phone in their hands, paying attention to every move in the "Sugar Triangle" live broadcast room.

"Old Luotou, you didn't say a word the whole time, and kept clicking on the screen, but what are you giving advice to this descendant?"

An old man with his back combed and wearing a Chinese-style Tang costume was talking, sat up from the Taishi chair, and took the old Luotou's mobile phone next to him to take a look.

Immediately crying and laughing.

This old man was not watching Lin Yi's live broadcast at all, but praised the young ladies who were scratching their heads and posing wildly on the amusement.

"Luo Gong, hello Yaxing! Seeing that the rising star of our northern faction is about to die in Xiqi, you are good, it looks like a beauty is coming. ”

This old Luo grinned and spoke in a Jinmen accent.

"Old man Bai, do you know that you have lost your conscience when you talk about it?

You called me from Jinmen early in the morning, and I didn't eat the pancakes and fruits, so you let me stare at them?

What's so good to see? What's there to see?

Isn't it a pastime?

Besides, I've already done it, but if there's nothing to do, you just put your heart in your stomach.

I think it's hard for them to encounter this little thing at all, hey, return the phone to me, don't give it to the young lady. ”

After speaking, he stepped on his round cloth shoes, reached out and snatched the mobile phone, crossed his legs, and sat back on the Taishi chair as if he were in a pit.

This set of movements is smooth, agile, and flexible, which does not match his appearance and age at all.

The old white man shook his head and smiled, put down his mobile phone and shouted into the room:

"Lulu, don't look at it, go, buy you a set of pancakes and fruits for Grandpa Luo, remember, beat two eggs."

"Oh, got it!"

There was a crisp sound of answer from inside the room.

A familiar figure walked out of the back room, and it turned out to be Bai Lu, who hadn't appeared for a long time.
