Aqua regia is the strongest acid, which is made of aqua regia with concentrated nitric acid and concentrated hydrochloric acid 1:3. It is really a must-have medicine for home travel and the destruction of corpses.

Of course, in fact, Aqua regia's ability to destroy corpses is not strong. And the ratio has not been completed yet, it is generally used now, otherwise it will be poisoned by chlorine.

If you are not in the industrial world, such as a processing plant, a manufacturer, you can't buy these two acids, let alone such a barrel in front of you!

Liquid nitrogen is not so hard to buy and is sold all over the country. Air detector, detect harmful poisonous gases, search a lot on the Internet.

When these three things arrived, Xu Laowei was really surprised and admired Zhang Wei's ability. No one knew that Zhang Wei was using his position to facilitate the purchase of an extra copy in the name of the company.

Even if he doesn't pay for it, for the amount of the factory, there is one bucket missing, and he can't see it at all.

Liquid nitrogen is a tin drum, storage type liquid nitrogen container, which is a bit difficult to carry. It's constantly leaking, and it has to keep leaking. Because liquid nitrogen will change from liquid to gas at room temperature, the more space is required, and the air pressure inside the tin drum will continue to increase, so nitrogen must be released.

Air detector, Luo Yuanhao can understand that there will be a lot of poisonous gas in the tomb, and this is tied to the back of the Tibetan dog, so that the Tibetan dog can run in, and then run out, you can analyze and judge the air quality inside.

But what do acids and liquid nitrogen do?

After listening to Zhang Wei's explanation, I realized that these two things were used to destroy the coffin. This family is relatively wealthy, and the material of the coffin is actually made of copper.

He planned to use aqua regia for the surface and liquid nitrogen for the lower part, so as to prevent the contents of the coffin from being corroded.

But he regrets it now, liquid nitrogen was purely deceived by netizens. Many netizens said that in film and television works, liquid nitrogen is sprayed on the metal, and then the branches are broken when they are knocked. Actually, it was filmed by people who didn't understand. Under normal circumstances, metals need to be soaked in liquid nitrogen for several minutes before they can be crushed, and not all metals do.

If liquid nitrogen is used to lower the temperature, and thus destroy the metal, it is almost impossible for the average boss surname.

Because once liquid nitrogen is sprayed out, it will turn into gas, and the gas liquid nitrogen is not cold, and it cannot freeze the metal at all, becoming a slag that can be broken when you knock it.

The reason why Zhang Wei still carries 40 liters of liquid nitrogen is that when he arrives at his destination, he will pour it all in one go to see if it will have any effect before all the liquid nitrogen is vaporized.

In the face of Zhang Wei's miss, Luo Yuanhao couldn't help but be a little complacent, this kid may be good at reading, but he is a weak chicken in practice.

However, Zhang Wei's next words still made Luo Yuanhao unhappy, because he said that after his calculations, the total mass of the covered part of the coffin could be completely corroded by the strong acid he carried.

It's just the sour smell it produces, which can kill people. Fortunately, he also bought a gas mask, cutting gloves and sleeve covers, all of which were one for each person.

It would be nice if one of them was good at gas cutting, cheap and convenient.

Among Luo Yuanhao's college classmates, there are several who like to read tomb robbery novels, and they like to communicate every day, but he has heard some of them, and he is not interested at all. However, these people are still complacent about this, feeling that the ancient "tomb robbery culture" is broad and profound.

Because what they communicate with is to use the oldest method to enter the tomb, and use the stupidest method to deal with the coffin, and then use the stupidest way to explore the mechanism, and use the most foolish method to deal with the zongzi, that is, zombies......

If it was a tomb robber hundreds of years ago, then forget it, but some of them were only a few decades ago, and at that time, as long as you had money, what you could do was much easier than now, and you could bring guns in, but there was no other equipment? What about logic? actually used such a stupid method to rob the tomb, and I was really speechless.

Naturally, he didn't know that these were all artistic processes, and although the real "archaeology enthusiasts" still use the old routines, there are also more professional ones.

Looking at Zhang Wei's basic equipment in front of him, it is obvious that the level has been raised a few streets.

However, he found that Xu Laowei also showed a look of surprise when he looked at these equipment, and finally understood. It is probably because these craftsmen are uneducated, self-contained, and they are passed down from master to apprentice, and it is difficult to communicate with the outside world, resulting in them only using stupid methods to "work".

If Zhang Wei does it, even if it is a sophisticated mechanism, as long as he is given a certain amount of time, he may be able to calculate a safe route for you!

This is probably the reason why he went from an ordinary dick to being able to get an annual salary of more than 200,000 yuan in the company, and he can also get dividends and be a technical director, right?

The two men settled in an inn and briefly studied the countermeasures again.

The place they were going to this time was the western half of the Tianmu Mountain National Nature Reserve in Zhejiang.

After passing the section of Tianmu Mountain, there is still a large section of mountain road to walk. In order not to let the nitrogen run clean, they had to get on their way as quickly as possible. As for what happens on the way, or after entering the tomb, it's only a matter of seeing the tricks.

Luo Yuanhao listened, and when he was sleepy, he went to sleep.

Five days off, and that's it. The next morning, Zhang Wei shouted him three times, and he felt that he was completely lifted from fatigue and his spirits became very good.

Hurriedly ate breakfast and took the car on the road. Since Zhang Wei had to be on duty for one day after four days of leave, they were actually a little late. Now, Old Monster Xu and his apprentices, except for the time to eat, must keep driving to catch up with the time to come back.

Luo Yuanhao's hand was itchy, and when he looked down, it turned out that the tail of the Tibetan dog touched the back of his hand.

After six hours in the car, his ass was stiff, and he quickly shifted his position and asked how long it would take to get there. When he learned that there were still 2 hours to go, he almost collapsed.

"Wait a minute, you have to go to the highway, you go to the toilet first." As he spoke, Mr. Xu parked the car on the side of the road, and several men each found an overgrown wasteland to solve the physiological crisis.

Liu Zongquan was also peeing, he yawned, looked up at the hillside not far away, suddenly trembled with fright, and suddenly urinated on his pants: "Fuck, there are wolves!" ”

Zhang Wei took two steps back while urinating, and looked at the direction where Liu Zongquan was looking: "German blackback, Erha, wolf green, Alaskan dogs, many of them look like wolves." ”

Luo Yuanhao trembled, closed the zipper, and leaned over to take a look: "It seems to be a wolf." I'll take a picture and Baidu it. As he spoke, he took out his mobile phone and took a picture of the wolf first, and then took a picture of Liu Zongquan's wet trouser leg......

"Alas, Master Luo, it's not good for you to do this......" Liu Zongquan hurriedly tied his pants and stretched out his hand to get it.

Luo Yuanhao suddenly burst into laughter and ran into the car.

Zhang Wei and Xu Lao Wei also laughed unkindly.

Zhang Wei returned to the car, took the Tibetan dog out of the car, and solved it.

Liu Zongquan was the last to return to the car, his trouser legs were even wetter, apparently somewhere to find a stream and wash it. Then Xu Laowei acted as a driver and continued to drive the road.

Luo Yuanhao used the method of picture search, and what he searched for was not a wolf, but a kind of wolf dog, which is estimated to have no owner and wander outside. It is 91% similar to a wolf, and at first glance it does look like a wolf. So he inquired about the wolf's information and popularized science to everyone.

It turns out that except for Taiwan Province, all other provinces and cities in China have wolves, mainly distributed in sparsely populated places. There are wolves in some places, but they are so few that people can't see them. So much so that in the whole of Zhejiang, there may only be thirty wolves.

As he spoke, he looked back out the car window and saw that the stray dog was hanging from a distance, following all the way.

However, as soon as the car entered the highway and the speed exceeded 120 horsepower, the stray dog disappeared in the blink of an eye.

Teresa Teng's music was played on the car, gentle and sweet, and a few people were drowsy when they heard it, but Xu Laowei himself was in high spirits, driving all the way for two hours, getting off the highway, leaving the town, and driving for more than ten minutes on the mountain road, and finally found the "organization" in a rural restaurant.

That is the descendants of Xu Laowei, one of whom is in his twenties, the son of the person who was rescued by Luo Yuanhao, and he will be the leader of the party this time. Xu Laowei said before that this great young man's name is Bai Baiqi, the most reliable, and the rest of the two have a Wan family luck and a Pi Yingfan, who is also a great young man.

Liu Zongquan and Xu Laowei drove for a day at a very fast speed, they were tired, and they still had business to take care of, and the two people lying in the hospital also needed them to take care of them, so they would not go this time.

Two barrels of acid were carried on their backs by Wan Jiayun and Pi Yingfan, and the two of them were silent, just hurrying. During the day, Qi didn't talk much, only said, something called me, and also carried liquid nitrogen on his body, just wanted to leave, he felt a chill in his back, so he put the bucket down, cut the bamboo next to it, and picked it up as a bamboo stick.

Even so, he didn't ask what was inside.

Zhang Wei had already run to the front, asking the two to not sway their backs, the things inside were very dangerous!

After walking for more than 20 miles, the sun was already in the west, and there was no hot temperature.

A few people finally arrived at the place, Luo Yuanhao took out his mobile phone to take a look, and there was no signal. He decided to bring an old drop-resistant mobile phone in the future, the kind with an antenna.

At this time, it was almost a real barren mountain and wild forest, and in the northwest direction behind him, three miles away, there was a village of dozens of families, and only six or seven old people were still farming, and no one could be seen.

In the mountainous area, there is no industrial pollution, the air is very good, and the environment is comfortable and pleasant to live in.

Luo Yuanhao saw with his own eyes that on the hillside, a snow-white rabbit disappeared in a flash, burrowed into the dry vines, and there was no trace. No wonder people often say that "running faster than a rabbit", the feeling that this rabbit is really fast running!
