The stuffy oil bottle looked at me in silence, and I met his dark gaze directly, but after a moment, he said something that was not in the mouth of the horse: "What is behind the bronze door, it is gone." ”

I was shocked and lost my voice: "Disappear? Is it ......?"

Could it be that the 'ultimate' has fallen into the hands of 'it'? According to the records I saw in the Kunlun Snow Mountain, the so-called ultimate behind the bronze door is precisely a thing that has been artificially put in, and since it is put in by people, it can naturally be taken away.

But didn't the stuffy oil bottle go to the bronze door to guard the door? How can something disappear?

The stuffy oil bottle looked at me and the fat man with a shocked face, and said lightly: "I'm not sure who got it, but the key to activating that thing is hidden here, and if I can't find out who took it, I can only destroy it." ”

I didn't know what to say about it for a moment, destroying it...... It turns out that this is the purpose of the stuffy oil bottle, the key behind the destruction and activation of the bronze door, so even if someone gets the so-called 'ultimate', it is useless.

In this way, the purpose of the group surnamed Zhang is obvious, and they also want to get what is here. In other words, what was behind the bronze door did fall into the hands of 'it', and in this way, the surname Zhang naturally became the enemy of the stuffy oil bottle, to be exact, my enemy.

It's no wonder that stuffy oil bottles are unusual.

Thinking of this, I feel even more dizzy, since the purpose of Dr. Zhang and the others at the beginning was the key to Yabuda's hiding, then why did Passerby A suddenly turn against him in the end?

I felt more and more that there was a lot of fog in this, and I didn't plan to ask about the ultimate thing, but after looking at the indifferent expression of the stuffy oil bottle, I couldn't help but ask: "Little brother, what is behind the bronze door?" ”

As I expected, the stuffy oil bottle immediately lowered his eyes and chose to ignore it, I didn't give up, changed the way, pointed to my feet, and said, "Then...... What's down here? ”

He shook his head, said he didn't know, and then continued with a flashlight, I smiled bitterly, knowing that I couldn't ask anything, the three of them went down in a row, during which I couldn't help but look back at the void above my head, and some pictures flashed in my mind from time to time, mostly the scenes of getting along with the surname Zhang, and I felt a little sour in my heart.

I know that such emotions should not appear, at least not at this time, at the moment passerby A does not know where to go, and we are walking towards the eighteenth layer of hell in the mural, and I don't know how long the effect of the medicine on the body can last, at this moment the love of children is not worth mentioning, maybe it will not be long before I will die violently, and then I will become a lonely ghost with the surname Zhang, then it is okay, there is no 'it' in the middle, maybe I can marry her.

Sighing, I pinched my own leg, and cheered up and went down, the stuffy oil bottle was very light, the cat was bent in front, the mountain wall was crawling with green vines, and everywhere he went, they cowered back like a snake afraid of brimstone, and made a way for us.

The further down I went, I felt the air getting hotter and hotter, and I don't know if it was psychological, but I actually smelled a faint smell of sulfur, and then, after a while, the stuffy oil bottle suddenly stopped.

I followed the light and looked, there was no road under his feet, the stairs were chiseled to this abrupt end, and when I looked down, I still couldn't see the bottom, I didn't have an illusion, maybe this cave did not lead to the eighteenth layer of hell, but to the other side of the earth, if I jumped down, would I fall directly to the South Pole?

The fat man looked around, snorted, kicked the gravel, and said, "This is the eighteenth layer of hell, naïve, take your phone and come out to take a photo." ”

I was upset by a push, how could I be in the mood to talk to the fat man, and casually perfunctory: "You have to find a partner for a group photo, our image is not good now, and we will take a photo when we go back and dress up." ”

At this moment, the stuffy oil bottle suddenly hit the light into the void, and then, my brows furrowed, I was startled by his reaction, Zhang Jiaqiling frowned, is it a blood corpse or something? Subconsciously, I leaned my back against the mountain wall, immediately became vigilant, followed the eyes of the stuffy oil bottle, and was suddenly startled, only to see the end of the flashlight, in the void parallel to our stone steps, there seemed to be a dark thing, faintly, like the shape of a coffin!

What's going on? When did this thing appear?

My heart moved, could this be the coffin in the mural?

At this moment, the light is too dim, I can only see a prototype in front of me, and I can't judge whether it is a coffin, at this time, the stuffy oil bottle suddenly pulled out the bronze chain knife from behind the waist, backhanded, and slammed into the stone crack of the mountain wall, and then, he turned out two palm-sized round objects from the equipment bag, I looked at it, and suddenly felt stunned, that is the front of the flashlight, can be replaced, it is densely packed with light bulbs, much larger than the current flashlight, and then, the stuffy oil bottle skillfully removed the small front head, Attach the big head.

I have always rarely associated the stuffy oil bottle with these modern scientific objects, watching him skillfully remove the flashlight, I suddenly found that I know too little about my brother, just like so far, I don't know the name of the fat man, and the stuffy oil bottle in my heart, should be a candle, holding an ancient knife to meditate, the result of the scene, made me feel very weird, without thinking, I don't know if the stuffy oil bottle will play Warcraft or war zombies or something.

Because of the skillful technique of dismantling the flashlight from the stuffy oil bottle, the flashlight suddenly skyrocketed, and the sequelae of my snow blindness were not healed, and I immediately closed my eyes, and even if I closed my eyes, there seemed to be a layer of red light flowing in front of me.

I blocked it with my hand for a moment, and only after my eyes adjusted to the light did I gradually open it, and suddenly, the scene in front of me made me stunned, no, not only dumbfounded, but I even stopped breathing.

At this moment, due to the diffusion of light, the true face of that black shadow was also revealed. It is indeed a coffin, it seems to be wooden, the coffin is a pitch-black color, it is carved with dense reliefs, because the distance is too far, with the relief to give me the feeling, I think it should be a unicorn pattern, of course, these are not the main thing, what is really unacceptable is that this coffin is floating in the air!

I have seen the hanging tripod of the Western Queen Mother, but it is suspended by a bronze chain, and the coffin in front of me has no chain around it, and there is no object to support it underneath, so it floats directly in the void, not moving at all.

I almost wondered if I was dazzled, and couldn't help but rub my eyes, at this time, the fat man next to me exclaimed: ", this tomb god, the coffin is hanging in the air, and there is no plane, how can the fat man open the museum?" ”

After a long time, the fat man was surprised not by why the coffin was hanging in the air, but by thinking about opening the coffin, I couldn't help but remind him, "This hanging coffin is simply a monster, do you really dare to think about it?" ”

The fat man's eyes were full of excitement, and when he heard this, he patted me on the shoulder and said, "The demon is also a coffin, it's a big deal to lie in the zongzi, the zongzi that the fat man shoots to death can form the Great Wall, and I'm afraid of one more of it, it's just ...... Tsk, how do you get there? ”

Bragging is too unreliable, using zongzi to build the Great Wall, Wufangzhai is not closed and bankrupt, I hit him and said: "This coffin is hanging in the air, if you go up, this weight will increase, maybe it will fall, and I won't be able to collect your body at that time." After speaking, I looked at the stuffy oil bottle and found that his expression was as usual, looking at the hanging coffin, and there was no look of surprise, I couldn't help but ask: "Little brother, do you know what is going on with this coffin?" ”

The stuffy oil bottle nodded, pointed to the bottom of the coffin, and said lightly: "It's the air flow." "Airflow? I thought that I had not reached Dr. Zhang's ability to be like an encyclopedic dictionary, and I was puzzled by the three words given by the stuffy oil bottle, and the fat man was enlightened and said, "Could it be that this coffin was blown up by the air current?" ”

Airflow? Blowing the coffin? Are you kidding? I just wanted to laugh at the fat man's unreliable imagination, but the stuffy oil bottle nodded and said lightly: "Bernoulli." ”

Bernoulli? I seem to have heard these three words somewhere, and I tried to recall them in my mind, and the vague memory suddenly made me feel excited, Bernoulli? Will the stuffy oil bottle actually know Bernoulli? I suddenly looked at him like a monster?

In 1726, Bernoulli, a foreign scientist, discovered the "boundary layer surface effect": when the fluid velocity increases, the pressure at the interface between the object and the fluid will decrease, and vice versa, the pressure will increase.

In honor of the scientist's contribution, the discovery became known as the "Bernoulli effect".

Bernoulli effect applies to all fluids, including gases, is one of the basic phenomena when the fluid flows steadily, if you use more professional terms, most people may feel very distant, I remember the first time I heard this word, it was in an elective course in college, the tutor gave a few very vivid examples, such as why the ship can move forward quickly with its sails, why it can be suspended by blowing a table tennis ball with a hair dryer, why a steel plane can fly into the sky, these are all related to the air flow, and change the air flow, You can control the pressure around the object, even if it is an airplane, it can fly in the air, so what is so strange about a suspended coffin?

I immediately went to look at the coffin, and then I found some strange places, Chinese coffins and coffins, are square, even in the West, one is big, the other is small, but with my careful observation, I found that this coffin design is very rounded, because it is a sharp corner, it is polished into an arc, it can indeed achieve a good effect of changing the airflow

However, this coffin is at least a product of more than 2,000 years ago, and Bernoulli's principle was confirmed in 1762.

I think this is a bit unreliable, and if it is really by changing the pressure of the airflow to form a suspended coffin, then the place we are in now, due to the airflow diversion, will inevitably feel a very strong airflow impact, but on the contrary, there is not even a trace of wind here, how can it be because of the airflow?

I looked at the stuffy oil bottle, although I was surprised that he would know Bernoulli's principle, but compared to this, I was more skeptical of his words, to be honest, I was in the bucket, I have always regarded the words of the stuffy oil bottle as a holy decree, he asked me to squat, I dare not lie on my stomach, but I have also received more than 20 years of modern education, compared to him, which is incompatible with modern society, I don't know how many years of life of the old antique, such a scientific principle, I think I still know better.

Therefore, I frowned, or said my doubts, before I finished speaking, the fat man hammered a punch on my shoulder, and said: "Naive, this is how you grow others' morale, extinguish your own prestige, what Bernoulli principle was discovered by foreigners, our Chinese ancestors have long found out, but our Chinese sons and daughters, adhering to the principle of low-key people and high-profile work, have always disliked publicity, for example, gunpowder was invented by us, how kind we Chinese are, use it to set off fireworks, how festive, Foreign devils are different, they were used to make cannons, and gunpowder became the world's weapon, in fact, sometimes it is not that the ancestors do not know, humility and accumulation, is the national style. You kid just read a lot of foreign books, and his mind is full of the Western market, and when you go back, the fat man will give you a good political lesson......"

I suddenly listened to the big head, what is this and what, didn't I just doubt the wisdom of the ancient people, I was actually pulled out by this dead fat man for such a large paragraph, which teacher did his patriotic education, it was so successful, usually even a break can be said wrong, a national wisdom, even idioms are used, he also knows humility? Grandma's, does he know how to write these four words?

I was about to tell the fat man that he was not thinking about the Western market, but was just objectively analyzing the situation, when the stuffy oil bottle suddenly looked at me, and then, with his strange long fingers, picked up a black stone the size of an adult's fist from the ground, and then he smashed the stone towards the coffin.

At this moment, the mutation suddenly appeared, the stone smashed out less than two meters, suddenly as if encountering a tornado, it was violently bounced back, and rubbed against the top of my head, followed by a bang, I looked back, after the stone hit the mountain wall, it was actually shattered by the huge rebound force, and my head hurt.

The fat man hid quickly, saw me covering his head, and said with a smile: "Who told you to doubt the wisdom of the ancient people, and you will be punished." ”
