Tianbao glazed top, the name of this thing sounds foreign, but it is actually a very vicious trap, spread a layer of pine grease on the top of the tomb, and after it solidifies, pour another fire oil with a very strong burning nature, seal the pine grease, and wait for it to completely solidify, seal it, and form an isolated independent space.

The white stratum corneum on the outside is a solid crystal formed after the solidification of pine oil, but it is actually very fragile, and under this white stratum corneum, a large amount of fire oil is stored, which is the real ruthless horn, and it is said that it will catch the wind.

This thing doesn't need to be ignited by an open flame at all, once it comes into contact with the air, it will spontaneously combust immediately, and the layer of loose grease wrapped around the outside is specially used to isolate oxygen.

The entire top of the tomb is filled with this fire oil, and once it is completely ignited, the intense heat will cause the air to expand, causing a huge explosion in the narrow grave pit, which is definitely more powerful than the old bell's previous preparation*, and the entire tomb will be buried by mountain rocks.

It can be said that this is a completely means of burning jade.

I carefully got off my feet, found the support point, didn't dare to touch the solidified pine grease, and slowly climbed up along the thief hole when I came, Ge Zhuang was already impatient, and asked me what is the situation below?

I said that the defense mechanism of the tomb of the Emperor is very in place, and the Tianbao glazed roof is not easy to break, and it seems that it takes a little more effort. Chen Yun was surprised, "Isn't the Tianbao glazed top an anti-theft method invented after the Song and Yuan dynasties, why did people before ancient times know how to use it?" ”

I smiled bitterly and said I don't know, give me a knife first, as well as a breathing mask and an oxygen cylinder, and then you can cover the hole with soil after I go down, and don't leak the oxygen.

The second master's "Feng Shui Notes" tells the method of cracking the Tianbao glazed roof, because this thing can only be arranged on the top of the tomb, so it must be dug from the side when playing the thief hole, but we don't have the energy to hit the second thief hole, and avoid the mechanism from the side, the rock layer in the valley is very thick, and I don't know if I have to wait until the year of the monkey to make a hole from the side.

So I chose another more risky method, first go down the hole, and then let Chen Yun use soil to cover up the thief hole, and re-form a sealed space, because the thief hole is not deep, so the air stored here is also limited, as long as you find a way to extract all the oxygen in the thief hole, the fire oil in it will not burn.

As for how to evacuate the oxygen in the cave, I had already thought of an idea, and when the people above covered the hole and sealed it again, I took out a candle from my duffel bag, lit it one by one, and fixed it in the pit.

The flame on the candle burns slowly, which consumes the oxygen in the cave little by little, and the hole is sealed and cannot be convection, so the oxygen gradually becomes thinner as the candle burns.

I waited for more than ten minutes, until I felt a tightness in my chest and it became difficult to breathe, so I hurriedly put the breathing mask over my face and docked the oxygen cylinder.

The capacity of the oxygen cylinder is limited, which can support my breathing for about two hours, which means that I only have two hours left to break the glass roof of this Tianbao, and once the two hours have passed and the candle has not been extinguished, then I can only give up.

After waiting for a while, the light on the candle head dimmed a little, and finally was pressed into a small green dot, I estimated the time, it only took about half an hour, and I was relieved that there was enough time left for me, and it seemed that this plan could be implemented.

It is obviously impossible to create an absolutely sealed environment here, but fortunately, most of the oxygen has been consumed, and the remaining oxygen concentration does not matter, but for the sake of caution, I still took out the match, tried to stroke it a few times, and the fire phosphorus on the matchstick "Zizizi" burned, and in less than a second, it was completely extinguished.

This oxygen concentration should be sufficient!

Confirming that the oxygen had been almost depleted, I crept onto the solidified layer of pine grease, took a few deep breaths, and then aimed the thorn at the side and tried to insert the knife into it.

Dude's move is completely playing with life, the oil stored under the lipolysis is on the wind, and I don't carry any protective equipment, once the outermost layer of coagulated grease is pierced by me, the liquid oil is directly exposed to the air, if the oxygen purity is enough, it can be ignited in an instant.

In that case, I will not be burned to death, an open flame is ignited in the narrow space, the temperature will also increase, and the violent expansion of the air will cause a big explosion, whether it is me or Chen Yun who is guarding outside the robbery cave, one is counted as one, and they all have to be finished!

I pursed my lips, my fingers trembling with the military thorn, and I hesitated for a while before I gritted my teeth and stabbed the dagger along the pine grease on the outer layer of the Tianbao glazed top.

Because the outermost layer of grease is solidified, so there is a certain hardness, I cut two knives in a row, only to pull a hole in it, the blade pressed, the force to push up the white cuticle, after the sound of gurgling water, the red liquid oil surging towards me.

The fiery red pillar of oil splattered into the blackened soil and melted into the soil little by little, so that as long as all the oil seeped into the ground, there was no need to worry about being ignited.

The devil knows what method people in ancient times used to refine this extremely flammable fire oil, which has a lower ignition point than white phosphorus, according to the record in the "Feng Shui Notes", this thing will be ignited even in the ice at minus ten degrees Celsius, as long as the oxygen concentration is sufficient, it can be said to burn wherever it is.

The white film of clotted fat on the outside of the oil was pierced several times in succession, and the fiery red oil pillars also splashed in different directions at the same time, and slowly penetrated down the stone wall, seeping into the soil little by little.

This process is very long, it is tantamount to walking on the tip of a knife, the slightest carelessness is the end of the jade burning, what I am most afraid of is that the people guarding outside can't wait, afraid that I will suffocate below, and open the sealed thief hole at once, so that the air will form a convection again, and I will become a fire man in an instant.

Fortunately, the people above were very calm, and what I feared did not happen, and when all the oil flowed out along the hole I had chiseled out, and all of it seeped into the soil, I finally breathed a long sigh of relief, and the whole vest was already covered in cold sweat, cold and cold.

The air pressure joints in the tank screeched, an alarm that the oxygen stored in the tank was running out, and it would last for fifteen minutes at most, and I remained squatting there for a few seconds, motionless.

It wasn't until the oxygen tank was completely depleted, and I myself felt that I was gradually unable to breathe, that I crawled to the entrance of the cave with difficulty, and chiseled hard into the sealed thief hole.

The people guarding outside sensed that I was calling for help, and hurriedly removed the sand covering the surface of the cave, I held my breath, and my heart was trembling, in case the oil was not cleaned by me, when the sand was shoveled, the air leaked, and I was afraid that I would have to see life and death in a second.

In a complicated wait, the sand covering my head was pried open by the sapper shovel, and in an instant I was exposed to the air, and without even bothering to breathe, I used my feet to get out of the hole.

Because the air had formed a convection, I could clearly feel the heat surging under my buttocks, which was the effect of the residual fire oil being ignited, and the pillar of flame that was sprayed was like a hideous poisonous python, which had already licked my ankles!

I grabbed Ge Zhuang's outstretched arm tightly, arched my buttocks hard, and the whole person suddenly jumped out, and the moment I jumped out of the thief hole, a bright pillar of fire also "stabbed" and jumped out of the thief hole.

The pillar of fire was in the form of a splash, soaring high into the air, soaring to a height of four or five meters, like a small bud growing vigorously, twisting in the air, emitting a crimson heat, which frightened everyone.

"Run!"

I shouted, and everyone turned around and rushed out of the valley, Ge Zhuang asked me as he ran, "Didn't you clean up the oil and why is it still burning?" ”

I said how can it be so easy, there will always be a remnant of it, but fortunately, the hole was not blown up, proving that my plan should have succeeded, wait, this fire may not be extinguished for a while.

Although most of the oil had seeped into the cracks in the rock wall, only the remaining part of it could burn so violently, but I didn't expect it, it was so dangerous, I almost let the tongue of fire lick my ass just now.

We found a relatively distant position and stood still, looking back at the flames rolled up in the cave, seeing it burning fiercely, everyone's hearts were filled with a sense of depression, the flames burned for four or five minutes, and the fire slowly suppressed it, it is hard to imagine what it would be like if all the oil burned at the same time.

Chen Yun was relieved when he saw that the fire was small, and whispered Sima Nan Thank you, it seems that you have learned a lot from the second master's book. I had palpitations, and said that it was better to wait, the fire was burning so fiercely just now, it is estimated that the temperature in the thief cave is very high, and now I take the fat man down, maybe I will become a roast boar when I pull it out.

The team continued to wait for an hour or two before I walked to the edge of the cave again, tested the surface temperature with the back of my hand, and found that it was not so hot, so I stood up and nodded to Chen Yun, saying that I could go down.

Lu Chuan said that you should go first, see how professionally you handle it. Ge Zhuang raised the corners of his mouth disdainfully, scolded and said Little pumpkin, this time it's my turn to be fat, you look at it above, but don't let the fat man and me become a roast pig!

Seeing that he took the initiative to ask for help, I untied the nylon rope, tied a few knots and put them on Ge Zhuang's waist, and the three of them dragged him and slowly lowered it.

I squatted at the entrance of the cave and held the rope, and said fatty, can you not just think about eating, what is the situation, squeak? He replied angrily from below, "It's okay, I can barely stand it, you guys come down too, I found the entrance to the cave." ”
