The cheap heard my muttering and said on the side: "It's not easy to know if there is enough oxygen in here, just take two sips and try it!" As he spoke, he raised his hand to take off the oxygen mask on his mouth, but fortunately, Wen Qingshan, who was on the side, was quick to hold him up, and shouted: "Don't take the risk!" Not to mention whether there is enough oxygen in this tomb, even if there is, it is impossible to breathe. ”

"Why can't you breathe when you have oxygen?" Asking, he asked.

Wen Qingshan said very sternly: "Because the Qinling Tomb contains a large amount of mercury, and the mercury will slowly volatilize, so the air in the Qinling Tomb must contain a high concentration of mercury, and as long as the concentration of mercury in each cubic meter of air reaches 8.5 milligrams, once a person inhales it, it will immediately cause acute poisoning, which is not good or even life-threatening!" ”

After listening to what Wen Qingshan said, he was so shocked that he didn't speak for a long time, and he didn't dare to risk his life again.

Wen Qingshan said: "It is not difficult to know if there is oxygen in this tomb, I have brought a portable air detector, which can detect the main components in the air. With that, he took the backpack off his back, opened it, and quickly took out a palm-sized instrument with an LCD screen on it, which at first glance looked like a walkie-talkie. I've never seen this device, but I don't have to ask to know that this is what he calls an air detector.

Wen Qingshan held an air detector to test the air in the tomb, looked carefully at the display screen on the instrument, raised his head and said to everyone: "The oxygen content in this is already at a fairly low level, less than 1%, the concentration of carbon dioxide and carbon monoxide is relatively high, and the concentration of carbon monoxide has even reached 1,300 milligrams per cubic meter, which is far beyond the level that can cause death, in addition, the air also contains a large amount of mercury." Therefore, you must not take off the oxygen mask to avoid accidents. ”

After listening to what Wen Qingshan said, everyone subconsciously touched the oxygen mask on their faces, as if they were afraid of falling off.

Wen Qingshan turned his head to look at the large pile of rusty iron tools in the tomb again, and said: "1% oxygen content is not enough to oxidize the substance, I think these tools should be rusty not long after the mausoleum was built, and later after the mausoleum was sealed, the oxygen in it gradually ran out, and the oxidation process stopped, so these tools only have a layer of rust on the surface." ”

"Will the painted pottery on the terracotta warriors and horses in the mausoleum also oxidize?" The fat cow asked worriedly.

Wen Qingshan replied: "If metals such as bronze and pig iron have not been treated with anti-rust, it is inevitable that there will be some rust, but the oxygen in the mausoleum should have dropped to a very low concentration level in a relatively short period of time, and I think the painted pottery on those terracotta warriors and horses will not be oxidized so quickly." ”

Listening to Wen Qingshan's answer, Niu Fat Man breathed a sigh of relief, since this guy followed Wen Qingshan to study antiques, he had a special emotion for cultural relics, he was afraid that the cultural relics in this ancient emperor's mausoleum would be destroyed.

Since the wooden door had been completely deformed, it couldn't be opened at all, Long Jiansheng didn't pay attention to it so much, and kicked a few times at the wooden door, Wen Qingshan hurriedly stepped forward to stop it, but it was a step too slow, how could the already somewhat rotten wooden door withstand such a few heavy kicks from Long Jiansheng, the entire wooden door was kicked open in an instant, and the door panel was also cracked into several pieces.

Looking at the wooden door that was destroyed by Yan Zhan, Wen Qingshan shook his head and sighed: "This door is also a cultural relic, and it is really a pity that it was destroyed like this." ”

Long Jiansheng didn't pay attention to Wen Qingshan's sigh, passed through the wooden door, and wanted to go forward, but at this moment, the old ghost suddenly stepped forward with an arrow and blocked in front of Long Jiansheng.

The old ghost said coldly: "You guy, didn't you hear what he just said? ”

Long Jiansheng said very indifferently: "It's just a wooden door, what's the fuss." ”

When the old ghost heard this, he became angry and shouted, "Hmph! This wooden door has been standing here for more than 2,000 years, but it has been kicked by you a few times, you actually think it doesn't matter!? ”

Although I also think it's a pity that this wooden door was kicked like this, but I didn't expect the old ghost to be so angry, Wen Qingshan hurriedly stepped forward to play a round: "Forget it, old ghost senior, I think Brother Jiansheng is also unintentional." ”

The old ghost snorted lightly: "Thinking that you are the first time to commit a crime, I don't care about you!" But if you do it again, don't blame me for being unkind to you. ”

As soon as the old ghost's words fell, Long Jiansheng had already turned around and continued to walk forward, seemingly not taking the old ghost's warning to heart at all.

The old ghost became more and more annoyed, and scolded: "Damn, what kind of attitude do you bastard boy! How could Long Jiu accept such a righteous son from you! "Scolding and scolding, but the old ghost didn't dare to fight with the dragon sword like he just put down the cheap, this guy is deeply hidden, and there is a murderous aura in his eyes, he must be extremely skilled, if he really moves, the old ghost may not be his opponent.

Because Long Jiansheng never responded, the old ghost was not interesting to scold alone, and Wen Qingshan had been persuading him on the side, his anger gradually calmed down a little, and finally stopped, but he looked at Long Jiansheng with a little more dissatisfaction in his eyes.

A group of people crossed the wooden door, and then walked not far ahead, a nearly three meters wide, about five or six meters high arched corridor appeared in front of us, the corridor stretched straight forward, full of twenty or thirty meters deep, on both sides of the corridor, every four or five meters away correspondingly stood a pair of armored, holding spears of samurai terracotta figurines, the terracotta figurines are lifelike, the colored glaze on the body is clearly visible, at first glance, as if there are really two rows of samurai.

Because they were worried about traps, everyone seemed very cautious and didn't dare to go too fast, for fear of accidentally touching the traps.

However, sometimes the more we try to avoid things, the more likely it is to happen, we are walking, and suddenly there is a "click" sound from under our feet, it seems that someone has stepped on the mechanism! Everyone hurriedly stopped, and the old ghost turned his head and asked, "Who stepped on the mechanism?" ”

The fat cow replied nervously, "Okay...... It seems to be ...... It's ...... me."

Before he finished speaking, he only heard a few "whoosh" sounds, and the old ghost immediately shouted loudly: "Be careful of hidden weapons!" ”

However, because it happened so suddenly, I didn't even have time to react, I was shot in the chest by a crossbow arrow, and despite wearing body armor, I felt a throbbing pain in my chest, as if I had been punched hard.

The crossbow arrows were shot from the front, Wen Qingshan and Long Jiansheng didn't dare to slack off, and hurriedly waved the weapons in their hands airtightly, with a few sounds of "bells", the crossbow arrows were blocked by the two of them a lot, but it was inevitable that they would still miss so many arrows, and in addition to me, Niu Fatzi was also hit by an arrow, fortunately, it was also shot on the body armor.

After a burst of crossbow arrows, the corridor soon returned to calm, I took off the crossbow arrows entangled in the high-strength fibers of the body armor, the body armor was not shot through, but judging from the holes left by the bullets on the body armor, its power may have been comparable to that of ordinary pistol bullets, I really didn't expect the power of this crossbow arrow to be so huge, I couldn't help but break out in a cold sweat.

I took the crossbow arrow in my hand and examined it carefully, it was about a foot and a half long, and its whole body was dark blue, it should have been made of bronze, and there was not the slightest trace of rust on the crossbow arrow. It seems that as Wen Qingshan said, the crossbow arrows have been treated with anti-rust, which means that the hidden weapons in the tomb can still operate normally, which is not a small threat to us.

The old ghost cleaned up, and there were more than a dozen crossbow arrows shot out, he frowned and said, "This should be a three-shot mechanism crossbow, everyone had better be careful." Speaking of this, he turned to the fat man and asked, "Where did you step on the mechanism?" ”

The fat man was still shocked, and he was stunned for a moment before he came back to his senses, looked down, pointed to a boxy floor tile, and said tremblingly: "Okay...... It's like that brick ......."

The old ghost walked forward slowly, squatted down, and after a careful observation, he turned his head and said to everyone, "You guys squat down first!" ”

I don't know what he is going to do, but in this mausoleum, after all, he has the most experience, everyone hesitated for a while, and they all squatted down according to his instructions, but everyone was very nervous, looking around, for fear that another crossbow arrow would be shot.

The old ghost glanced at everyone and said, "Squat down, if you hear movement later, don't look up!" ”

The cheap couldn't hold it back, and asked, "What are you doing here?" ”

"I'll try this mechanism!" After the old ghost finished speaking, he actually stretched out his hand and pressed down on the floor tile that the fat cow said.

I didn't expect him to take the initiative to press the mechanism, it was too late to stop him, everyone hurriedly turned their heads and looked straight ahead, Wen Qingshan and Long Jiansheng both raised their swords in their hands, ready to resist the crossbow arrows.

I only heard the sound of "click", my heart pounded, and everyone held their breath, but after waiting for a while, there were no crossbow arrows, and there was no movement.

The cheap muttered in a low voice, "What's going on?" Could it be that the crossbow bolts have been shot just now? ”

As soon as he finished speaking, the old ghost said, "How can the crossbow arrows be shot so easily!" It's just that I haven't really touched the mechanism yet. ”

Hearing him say this, I subconsciously turned my head to take a look, only to find that the floor tile was about ten centimeters pressed by him, and his hand did not let go, still pressed hard.

Everyone didn't understand why, but the old ghost explained: "The principle of this mechanism is somewhat similar to that of a loose mine, it doesn't shoot crossbow arrows when you step on it, but it actually makes the bow and crossbow tight, and as soon as I let go of my hand, the crossbow arrows will shoot out immediately." ”
