Jiang Yongguang's unbridled laughter echoed in the empty and dark cave, making the atmosphere of the scene more and more strange and inexplicable.

The timid Xiao Liang couldn't help but cover his ears and shouted: "Officer Jiang, can you stop laughing, it's strange ......"

The other Xiaolingwei couldn't help but ask:

"Dayong, what are you laughing at?"

"What kind of wind?"

"What the hell is going on, you are talking!"

“……”

I couldn't suppress the curiosity in my heart, and walked over to Jiang Yongguang's position to take a look, but my eyes swept over, and I finally understood why he was laughing.

I saw that the bronze figure on the right did not disappear out of thin air, but for some reason it suddenly shattered into a pile of broken copper and iron, scattered on the ground, which gave people the illusion of suddenly disappearing.

As for the roar of metal that echoed behind us just now, it was the sound of the fragments of the bronze figure falling to the ground.

At this time, Jiang Yongguang finally stopped laughing and said to everyone: "What bronze statue is alive, and it will come to kill us...... What nonsense, come and see for yourselves, it's the bronze statue that shattered on its own. ”

Everyone came forward one after another and finally figured out the truth.

The timid Xiao Liang also breathed a sigh of relief, and his expression became much more relaxed.

However, seeing such a magnificent and exquisite cultural relic suddenly shattered into a pile of broken copper and iron, she couldn't help but show a distressed look, and said regretfully: "This bronze statue is good, how can you say that it is bad?" None of us touched it, how did it shatter like this? ”

Jiang Yongguang smiled and asked Xiao Liang: "Have you heard of a term in archaeology, which is called - dry for a thousand years, wet for ten thousand years, and half a year if it is not dry or wet." ”

Xiao Liang shook his head blankly: "I haven't heard of it." ”

I hadn't heard this before, and I subconsciously asked, "What do you mean by that?" ”

Jiang Yongguang said: "It's very simple, it's literal. If the artifact is kept in a dry environment, it can be stored for thousands of years, and if it is kept in a sealed water environment, it can be stored for 10,000 years. However, if it is an alternate wet and dry environment, then it will be stored for half a year at most. ”

At this time, Uncle Mei on the side sneered and said, "What are the terms of archaeology, I think these are all mantras for robbing tombs and digging graves, right?" ”

Jiang Yongguang's expression was embarrassed, he hesitated for a moment, and finally admitted: "This sentence was indeed summed up by tomb robbers at the beginning. The ancient tombs can be roughly divided into two kinds, one is the completely dry pit tomb, the rat of the southern school calls it the fire cave, and the other is the water hole tomb, commonly known as the water cave, and the cultural relics in the water cave are often more well preserved than the fire cave......"

However, at this point, Uncle Mei squinted his eyes and questioned, "What you said is not right, right?" How can I hear people say that those who are upside down love to turn over fire holes, but not water holes? ”

Jiang Yongguang smiled and said, "This involves the conservation of cultural relics. Cultural relics in the water environment can indeed be preserved more well, and even after thousands of years, they are still the same as new, because the water environment naturally seals the cultural relics and avoids the cultural relics from being exposed to the air and oxidized. However, once the artifacts in the water come out of the water, they must be carefully maintained immediately, otherwise once they come into contact with the air and are detached from the buoyancy of the water, then these artifacts will become extremely fragile and even collapse on their own without touching them......"

Hearing this, I immediately came to my senses, pointed to the pile of bronze fragments at my feet, and asked:

"So, this bronze statue must have been kept in a sealed water environment before, but now that the water level has dropped, it has surfaced, lost the buoyancy of the water, and came into contact with the air, so it will automatically collapse and shatter?"

Jiang Yongguang nodded and said, "It seems that this is indeed the case." ”

Later, he said to Uncle Mei: "The rats who robbed the tomb did not have enough time to maintain the cultural relics in the water cave, and the cultural relics taken out of the water cave were basically destroyed on the spot, and could only be repaired later, so that the integrity of the cultural relics themselves was destroyed, and the artistic value was greatly discounted, and it was difficult to sell them at a high price, so the rats did not like the water hole, and preferred the fire cave." ”

Uncle Mei nodded slowly.

Jiang Yongguang added: "But even so, the rats will not let go when they encounter the water hole, they don't care if the cultural relics will be destroyed, after all, even if they dig out some fragments of cultural relics, they can still make a profit." ”

Hearing this, Xiao Liang said angrily: "How many precious cultural relics have been destroyed by this group of tomb robbers!" ”

Jiang Yongguang sighed: "Yes. In particular, most of the water caves themselves are sealed water environment, but once they are stolen and excavated, they become neither dry nor wet - not dry or wet for half a year, and the remaining cultural relics in the ancient tombs will be quickly destroyed in a short period of time, even if they are not stolen by the rats. ”

"No wonder you filial piety guards hate tomb robbers so much." Xiao Liang said quietly.

Jiang Yongguang shook his head and said: "The reason why we hate rats is not only for this reason, the threat of rats to historical relics and even the entire Chinese civilization is far more serious than this, I will explain to you slowly when I have time......

Then he pointed to the back of the bronze giant door and said, "At present, it is likely that this ancient tomb was in a completely sealed water environment at the beginning, and after being punched by a rat into the water, the sealed environment was destroyed, the water level dropped, and the ancient tomb was exposed. We must locate the tomb as soon as possible and notify the relevant authorities to carry out a salvage excavation. ”

The other Xiaolingwei also immediately realized the seriousness of the problem, and without hesitation, they successively drilled into the ancient tomb along the gap of the bronze giant gate.

I followed them and followed them into the bronze gate, but I don't know if it was because I had consumed too much physical strength during this time, or because the oxygen in the underground cave was relatively thin, and the moment I stepped into the ancient tomb, I suddenly felt a sense of dizziness and weakness in my legs.

Xiao Liang, who was walking in front of me, apparently had the same reaction, and she was crooked and almost fell to the ground.

I hurriedly reached out to support her and whispered, "Are you okay?" ”

Xiao Liang smiled apologetically at me and said, "Maybe it's a little hypoxic, my head was a little dizzy just now, and my eyes are full of gold stars." ”

I said I had the same reaction, could it really be that there was not enough oxygen in the tomb?

Out of vigilance, I hurriedly called out to Jiang Yongguang and reminded: "Xiao Liang and I were both a little hypoxic just now, this ancient tomb is getting deeper and deeper, there shouldn't be no oxygen in it, right?" ”

Xiao Liang also added: "And in this kind of underground cave, it is easy to have toxic gases, right?" ”

Jiang Yongguang smiled, took out a black instrument similar to an elderly person's mobile phone from his backpack, and said, "You don't have to worry about this, I have prepared an air composition detector here, if the oxygen content is really insufficient, or there is a toxic gas, it can be detected." ”

Other filial piety guards also comforted us: "Don't worry, it's not the first day that we have gone to the grave, and we are still prepared for this." ”

Xiao Liang and I were relieved and stopped and waited for Jiang Yongguang to test the air composition.

Everyone else rested in place for the time being, and no longer moved on, and the tomb suddenly became deathly quiet.

At first, I only heard the sound of the air composition detector in Jiang Yongguang's hand, but suddenly for a moment, I was faint in my mind, as if I heard a whisper from the depths of the ancient tomb......
