Just when I felt that it was impossible to enter this tomb, the seventh master took out an oxygen cylinder from his backpack, this oxygen had been packed in the backpack very early, I had been wondering, I wanted to ask, but because the situation was too complicated to enter the tomb, I forgot about it.

Now that the seventh master took out the oxygen cylinder again, I opened my mouth and asked, "Seventh master, what do you mean by this oxygen cylinder?" Is it hard to dive into mercury? ”

The Seventh Master shook his head with a smile, and said, "In the ancient tomb, there are many mechanisms made of mercury, I have encountered a lot, I have encountered a lot of them, I have also encountered this kind of sophisticated mercury tomb before, when we came, I felt that the real unicorn eye should be in this ancient tomb, and the unicorn eye I stole before was stored in the coffin of Jiulongtai, just in case, I brought this over, specifically to deal with this kind of sophisticated mercury mechanism tomb!" ”

Saying that, the seventh master slowly unscrewed the lid of the oxygen cylinder with his hand, and a white weapon came out of the bottle, Wang Chuyi, who was closest to the seventh master, shuddered and hurriedly asked, "What is it, so cold?" ”

Seeing this, I immediately understood what the seventh master meant, and said, "It's liquid nitrogen!" ”

At atmospheric pressure, the liquid nitrogen temperature is -196°C, while the freezing point of mercury is -39°C.

The seventh master nodded, and said, "This is what I dragged someone from the United States, highly concentrated liquid nitrogen, only about two or three spoonfuls of the amount, can quickly lower the temperature of this mercury, as long as the mercury solidifies, the mechanism in this tomb will naturally be self-defeating." ”

Huzi looked at the Seventh Master almost incredibly, with his cultural knowledge, it was difficult to understand the substance liquid nitrogen, and Wang Chuyi's eyes as if looking at a fool told us that she would never explain to Huzi what liquid nitrogen was.

In this way, under our gaze, the seventh master carefully put a spoonful of liquid nitrogen into the mercury.

The ripples from the mercury at the beginning of the period were quickly solidified, and when the seventh master put in the second spoonful of liquid nitrogen, the mercury had already begun to solidify on a large scale, and at this time I was able to breathe a sigh of relief.

At this time, the seventh master looked at his watch and said, "I estimated the area of this tomb, it takes about two minutes for the mercury to solidify, and the time for us to enter the tomb is only fifteen minutes, after fifteen minutes, the mercury will gradually return to a liquid state, we must watch the time!" ”

As he spoke, the seventh master took the oxygen cylinder and put it in the backpack again.

At this time, Huzi said, "Seventh Master, if I don't stay here, I will put two more spoonfuls when I see the mercury quickly turn back into liquid." ”

The Seventh Master shook his head and said, "There are eight tombs like this, if you use them all up here, what will happen to the rest of them?" Stop talking nonsense, hurry in and find out, time is running out! Saying that, the seventh master looked at his watch again, and after making sure that the mercury had been solidified, he immediately walked towards the interior of the tomb.

We followed behind the Seventh Master, because the Seventh Master already had experience in exploring this kind of tomb, so we quickly found the dragon carved stone tablet, which was inlaid on the wall on the northwest side of the tomb, about two meters high from the ground, shining a flashlight, and could not see the lines on the stone tablet clearly, so we needed to get closer.

The height of the seventh master is limited, so he can only let the tiger squat on the ground, the seventh master rides on the neck of the tiger, and the two of them stack the arhats, so that they can smoothly touch the stone plaque.

"Seventh Master, time is running out, there are eight minutes left." I don't know how long it will take for the mechanism on this stone tablet to be cracked, so I can only remind the seventh master in a whisper, and I secretly sweat in my heart.

I saw that the seventh master stared at the stone plaque for about three minutes, without any movement, and even his fingers did not touch the stone plaque, which made me and Wang Chuyi anxious, looking at this posture, it is obvious that the seventh master does not understand this stone plaque very well!

"Seventh Master, there are five minutes left!" I hurriedly reminded that if my heart said no, I would quit first, and then ice the mercury again, and I would be able to buy fifteen minutes, and it would not be too late to study it slowly.

But at this moment, the fingers of the seventh master moved, I looked very carefully, the fingers of the seventh master pressed on the far left side of the stone card, about the position of the dragon's tail, and then turned up half a circle, stopped for a second or two, and then turned up half a circle, and stopped for one or two sides, and then twisted the whole stone card clockwise for a circle and a half, and then reached out and patted the tiger's head, and said, "Okay, let me down." ”

After Huzi put down the seventh master, we didn't stop here for a second, turned around and walked towards the outside of the cemetery.

I was the first to come out of the tomb, after seeing the situation outside the tomb, I was stupid, I could hardly believe my eyes, just now it was still a cliff outside the tomb, now there are lush trees, and very dense, each one is about the same thickness, about the thickness of my thighs, at a glance, I can't count how many.

"Seventh Master, this... What the hell is going on? We... Are we entering the illusion again? So saying, I stepped forward and struck twice on the trunk of the tree closest to me.

"That's not right! That doesn't sound right! ”

I clearly felt that the middle of the tree was hollow, which made me startled, and I quickly looked up, if the middle of the tree was hollow, it would definitely not survive, if this was the case, what about the lush leaves on the tree?

"Vines, it's vines, old white, come back quickly!" Huzi exclaimed, and hurriedly rushed towards me, and then pulled out the clothes and dragged me backwards.

By this time I was already feeling weak, and when I looked down, I saw that a very inconspicuous vine had climbed up to my feet at some point, and its rhizome as thin as a needle had pierced into my skin, and I felt no pain at all.

At this time, the seventh master also rushed over, when he saw the vines on my feet, the expression on his face couldn't help but change, and my heart twitched, and the seventh master's expression was clearly saying that this vine was a * annoyance.

Huzi quickly dragged me to the wall of the tomb door, but at this time, the vines wrapped around my feet were also dragged out one after another, Huzi drew his saber and slashed at the vine, this vine is not thick, where can withstand Huzi's hard slashing, and it will be broken in two in an instant.

At this moment, a foul smell of blood came into my nostrils, I looked down, and saw that the cut of the vine that was cut by the tiger began to squirt out a bright red liquid, I judged that it should be blood, and when this blood sprayed on my ankle, I felt warm, could it be that these vines are alive?

"Seventh Master, the blood spurting out of that thing won't be poisonous, right?" Huzi hurriedly inspected my feet.

The Seventh Master said in a deep voice, "Of course it won't be poisonous, because that's Lao Bai's blood, which was sucked by that vine!" ”

After speaking, the seventh master hurriedly picked me up, and then took out a white wax pill from his arms, and after pinching it hard, inside the wax pill was a black pill the size of a thumb.

"It's almost eating."

The seventh master stuffed the pill into my mouth, I only felt very bitter, and with a fishy smell, this smell simply made me very uncomfortable, the pungent fishy smell instantly filled my entire nasal cavity, I felt that the breath I exhaled was fishy, I just wanted to vomit, I couldn't swallow it.

At this time, the seventh master's face changed, and he scolded, "If you don't eat it, you will have to die here!" Saying that, the seventh master slapped my stomach suddenly, and I opened my mouth with a painful sound, and before I could react, the seventh master slapped my mouth again, just slapping the pill into my throat, and then Wang Chuyi took out the kettle and blocked my mouth.

I gulped down the water and struggled to flush the pill down my throat.

After taking this pill, I instantly felt a bitter smell in my esophagus.

"Oh, my mother, what kind of medicine are you, Seventh Master, it's hard to eat, I swear I'll never take it again in my life."

As soon as the words fell, the seventh master immediately pressed my chest with his hand and said, "Don't speak, shut your mouth, try to hold your breath, don't breathe." ”

I saw that the seventh master's face was very serious, and I instantly realized the seriousness of the matter, and nodded hurriedly.

The seventh master's hand pressed my chest, almost pressing me to the point that I couldn't breathe, and then he quickly kneaded it, his palm and the skin on my chest began to rub and heat, and soon a large piece of my chest was rubbed red by the seventh master, and then began to get hot.

At this time, a cool feeling went up from my stomach, and when it passed through my esophagus, there was an inexplicable comfortable feeling, as if a cool gas was rising and had reached my throat.

At this time, I wanted to open my mouth to spit out this breath, but the seventh master covered his mouth and said in a low voice, "You can't spit it out, you have to use your nose to expel it little by little, remember not to be too fast, otherwise you will pass out!" ”

After the seventh master finished speaking, he still didn't let go of the hand covering my mouth, but instead shook my head twice with more force, and said seriously, "Do you understand!" ”

To be honest, this state of the Seventh Master is very rare, and I know that this time it is really dangerous, so I also nodded cautiously and began to slowly exhale the cool air through my nose.

Just as the gas was about to pass through my nostrils, I felt a tingling pain, like mustard coming out of my nose, and my tears flowed out.

Seeing that my eyes were tearful, the seventh master's face eased a lot, but he still didn't forget to tell me, "Exhale slowly, don't worry, this is the toxin on the vine, fortunately it was discovered early, and it can be forced out as soon as possible, otherwise, even the Da Luo Immortal will not be able to save you." ”

As I spoke, I exhaled slowly, tears flowed more than before, with this experience, I guess from now on, I will not touch this thing again, it is too uncomfortable!

"Seventh Master, quick, those vines are moving!" Wang Chuyi reminded in a whisper.
