"Did you lose anything?"

Zhang Wei touched his mobile phone, looked at the video taken yesterday, and when he saw the route all the way in, he was relieved. Nothing is more important than this.

Checked the food and tools again, and they were all there. It seems that the other party has no malicious intent.

I fed a piece of beef to the Tibetan dog, and the two of them took the dog in.

Quickly bypassed the table in front of him and pushed open the stone door on one side. Neither of them expected that the stone door would be pushed open very easily. Looking at the ground inside, there were new footprints.

From here, the Tibetan dog became a little nervous. However, according to the direction of the light, the internal air quality was detected. A little worse than the outside, there's also a toxin called mercury vapor.

In ancient tombs, mercury, arsenic, cinnabar, acetic acid, ethanol, carbon and other items were used for embalming in ancient tombs. Some are used directly for embalming corpses, while others are used in burial chambers.

Over time, these chemicals react with the air and surrounding substances, which can lead to deterioration, resulting in toxins.

For example, the carbon monoxide and carbon dioxide they detected may have been formed by the burning of wet wood before the tomb was closed. First, the gas is toxic and prevents tomb robbers, and secondly, carbon is an active substance, which can absorb all kinds of things, and can prevent moisture and keep it dry.

The ancients were also very smart.

The new toxin they detected was mercury vapor. The main component of cinnabar is mercury sulfide, which is generally not volatile. Therefore, the source of mercury vapor may be the mercury used for embalming in the tomb, which is a heavy metal, which will also volatilize at room temperature, in fact, it begins to volatilize from 0°C, and the higher the temperature, the faster and more evaporation; The evaporation rate increases by about 1.2~1.5 times for every 10°C. Mercury evaporates more as air flows.

Mercury vapor, which sounds like a powerful thing, is actually gaseous mercury. Just like water, there are three states: solid, liquid and gas.

However, mercury vapor in the air has a high diffusion and high fat solubility, when inhaled, it can be completely absorbed by the alveoli and carried throughout the body through blood circulation, but this kind of thing is not a necessary metal for the human body, so long-term mercury vapor environment can cause mercury poisoning.

What Zhang Wei means is that this level of mercury vapor, like carbon monoxide, can poison people for a short time, but it is best to wear a gas mask.

The two of them replaced the gas masks with filters to filter out mercury vapor. Relatively speaking, the concentration of mercury vapor at this time is more toxic than carbon monoxide. At the same time, they also put a filter box on the Tibetan dog to avoid long-term inhalation. This dog is still relatively smart, and seeing that Zhang Wei and they have brought it, it is not very disgusted.

Since he was in the hotel, he had already discussed the situation with Xu Laowei, so he was relatively clear about this place. Since the two of them are here to catch zombies, they immediately decided to let the Tibetan dog lead the way and find the source of danger, and the two of them can kill the zombies.

The female zombie in the coffin, if it can be taken, it will be great, if not, then it will have to come again next time.

Zhang Wei and Luo Yuanhao were more cautious and stuck a stone on the stone door to prevent the stone door from closing. Because this stone door can only be pushed open from the outside, and the inside is almost seamless, and it is difficult to break it!

A careless closing, it's troublesome to reopen from the inside.

The two of them continued to walk inside, and the passage became narrower and narrower, as narrow as the tunnel in the tunnel battle.

After a minute or two, I finally arrived.

Compared with the princes and nobles, the tomb is actually not big at all, slightly larger than the volleyball court, and slightly smaller than the basketball court. And there is no structure, it is a clever use of the naturally formed karst cave, and it is chiseled and reinforced.

In the middle and back position, there is a coffin, and the two people shine in the light: "It's broken!" ”

It turns out that the coffin has been corroded!

They didn't care about testing the air quality, so they hurriedly ran up to take a look, and it was too bad, the corpses inside were gone! Not only that, but the bridal maid on the right and the little maid on the left, their coffins were all opened, and there were no corpses inside.

Xu Lao Wei said that his brother did not move the corpse, even the female zombie who had been indecent was released again!

Zhang Wei hurriedly looked at the side of the coffin, where there was a large pool of water, almost flowing into a stream.

"With copper, a blue liquid is generated. with iron to produce a reddish-brown liquid. Bastard! These guys actually use aqua regia! And they just used it, no more than ten minutes at most! Because the two liquids have not yet reacted, only the edge part and the iron part of the coffin that has fallen to the ground have formed a reaction, and it can still be seen. Moreover, this coffin is not pure copper, with iron below and copper above. ”

Luo Yuanhao's attention was more focused on the coffins on both sides, he found some fungi inside the coffin lid, he immediately took out the knife, scraped it off a little, and then looked back at the outside of the coffin, and found a lot of small pieces, carefully identified, it was also a coffin fungus.

Legend has it that the growing conditions for the coffin fungus are harsh:

1. The material in the coffin must be of the highest quality;

2. Before the death is born, he must eat delicacies from the mountains and seas every day;

3. Must be a man;

4. Must be poisoned to death;

5. Must be a living person before entering the coffin;

6. This person was formed by spurting blood on the board in the coffin.

7. This person died on two hurdles, that is, a person who died at the age of seventy-three or eighty-four.

Of course, these quirky contents, Luo Yuanhao will use two words to negate:!

There are two necessary conditions for the growth of coffin fungus, one is warmth. It's just warmer and wetter. On the other hand, the wood used to make the coffin is more susceptible to decay and can absorb water. This is the necessary condition for the growth of coffin fungus.

He was very happy that if he could identify the medicinal value, he would be rich! Of course, if not, there is no weight anyway, then it will be lost.

There were three coffins here, and he ran to the other coffin, and the fungus on it was like a lump of fung......

How about going under the knife? Or go under the knife? Or go under the knife? Luo Yuanhao muttered as he got closer, like a roasted sweet potato......

In case it's a lump of Xiang left by a fool, Lao Tzu will beat him to death! Luo Yuanhao stabbed lightly with a knife, eh, hard Bangbang, rest assured!

Cut off the mushrooms in a coffin the size of a sweet potato, wrap it in a nylon bag, and put it in a school bag.

He lifted the coffin board again, and a huge Lingzhi suddenly appeared inside!

This Lingzhi is similar to the picture seen on the Internet, except that this one is a bit like a dead wood stump and a bit like a fluttering butterfly, but the black one is not beautiful.

Luo Yuanhao continued to scrape with a knife.

Because the coffin fungus is too large, the skin that the gloves did not cover accidentally touched it, and it felt not too hard, but a little soft. Then he felt his wrist start to itch.

He immediately stopped the knife, knowing that the fungus was poisonous. When he walked in front of the owner of the tomb, the coffin did not grow inside or out, so he had to give up.

He returned to the original coffin, continued to observe the coffin fungus, and took out his mobile phone to take a photo by the way, leaving a record.

He looked down and saw that inside the coffin, silk and clothes were used to cushion the corpse. He also took pictures. It's a pity that my hands are shaking this time, and the photo was not taken well. So he lifted the lid of the coffin a little, but at this time, he was stunned to find that there were scratches on the inside of the coffin!

It wasn't scraped by itself, who did it? Luo Yuanhao was a little puzzled, could it be that these guys also got into the dark inside?

He was thinking about it when his shoulder was suddenly pulled: "What are you doing?" ”

"Are you listening to me?"

"I'm listening. What this reaction, that reaction. Anyway, I'll give it back to the teacher, don't expect me to understand! ”

"I'm saying, I misjudged just now, they guys, it's been at least an hour, I've taken off my gas mask, and there's no pungent smell at all. There is no moving air here, and the chemical smell takes a long time to dissipate. ”

"Keep your dog on hold and don't let it pick up." Luo Yuanhao pointed to the Tibetan dog that was about to climb into the coffin and said.

Zhang Wei hurriedly pulled the dog back, and said to Luo Yuanhao: "They don't usually take corpses when they do this, why are they gone?" ”

When Luo Yuanhao heard the other party ask, he immediately stretched out his finger and pointed: "Look, I didn't shave it here." Xu Laowei said that his brother had not touched it, and it must have been those three guys who did it. ”

"However, Old Monster Xu also said that they have opened and seen these things, and they have already touched the valuable ones. The rest hasn't moved, huh? ”

Luo Yuanhao showed Zhang Wei the coffin fungus in the nylon bag: "How is it, do you know this thing?" ”

Zhang Wei shook his head.

"It doesn't matter if others don't know, you, I'm going to give you some science. This thing is called coffin fungus, and some people say it can cure heart disease, some say it can cure cancer, and some people say it can treat broken bones. In fact, the highest efficacy is only the level of Ganoderma lucidum, and everything else is basically nonsense. However, if we use it, it will really work, and our cadaveric penicillin, with it, it will be successful! ”

"You mean to say that this is missing from the prescription you gave me before?"

"Yes, because it's not very likely that a drugstore or a person can take it out and be a real guy. Of course, in addition to this thing, there is another difference in the prescription, and my impression is too vague to remember clearly. Probably dispensable. ”

"Then you hide it, let's go back and talk about it."

"Well, for other herbs, we can pick wild ones. This trip has been very rewarding. ”
