As the flames increased, the corpses on it were slowly burned, starting from the clothes on their bodies. In a moment, the corpses were burned to the flesh, and the smell became more and more unpleasant in the sound of "smack", which made everyone present have a strong sense of vomit. Seeing this, Professor Chen immediately made a decision: pour all the food and other supplies into the place where they came in, and then return immediately.

After returning to the Hades Temple, Zhang Gong pulled Professor Chen to sit in front of a monitor, and through the camera that had just been installed in front of the burial pit, it could be seen that the flames had now risen, and it was not a little bigger than when they left just now. It is also evident from the video synchronized by another camera that the ice on the nearby mountain has begun to melt.

Looking at the surveillance, Professor Chen sighed: "Alas, the temperature inside is bound to rise after such a burn, and I don't know what will happen to the impact on the inside." ”

Seeing Professor Chen's sad face, Zhang Gong comforted: "It shouldn't be too big, now I just don't know how thick the grease is in it, if it is thin, it will soon burn out." ”

"By the way, I'm wondering now, how did the fire burn?"

"What's so strange about the spontaneous combustion of phosphorus fire?"

"On the surface, it seems that phosphorus fire spontaneously combusts, but just now I suddenly remembered, has the environment there reached the conditions for spontaneous combustion of phosphorus fire? Can phosphorus fire ignite corpse oil? ”

"The spontaneous combustion of phosphorus fire belongs to the reaction of phosphine, not the result of real physical combustion, and the blue-green flame produced is also a chemiluminescence phenomenon.

"Since the environment does not meet the conditions for spontaneous combustion of phosphorus fire, where does the fire come from? In addition, in addition to being poisonous, phosphorus fire will not ignite the surrounding things, let alone the grease that decomposes from the corpse, so the question is, where did this fire come from? ”

When Zhang Gong heard Professor Chen say this, he suddenly understood why Professor Chen was puzzled, so he said in surprise: "Old Chen, you don't mean that this is artificially set on fire, right?" If that's the case, then there's a serious problem. ”

"Do you have any other explanation?"

"If you don't remind me, I really don't think this fire is strange, it looks like there's a serious problem in our team."

"The spontaneous combustion of phosphorus fire seems to give us a very legitimate cause of fire, but this illusion cannot withstand scrutiny, after all, we all know that phosphorus fire will not spontaneously combust in such an environment, even if it is spontaneously combusted, it is impossible to ignite the corpse oil, if you have to start igniting from somewhere, I personally think that it was artificially thrown into the fire source, igniting the methane gas inside and the cloth on the corpse, so that the fire can develop and expand; Since it is said that it was artificially set on fire, then what is his purpose? I think he probably knows what's down there, and he wants to get ahead of his goal! ”

"Lao Chen, your analysis is very probable, but we all clearly smelled the smell of phosphorus fire when it just happened, the ignition temperature of the corpse oil should be between 300-400 degrees, and it is impossible for ordinary fire sources to ignite the corpse oil, if this phosphorus fire is not the cause of the fire, then I think this should be man-made, he threw the chemical substance mainly white phosphorus into the hidden place under the burial pit, because white phosphorus needs to be in the humid air of about 40 degrees or dry high temperature before it will spontaneously combust, If you want white phosphorus to spontaneously combust, you need to put it on other things that help to heat it, heat the white phosphorus through that substance, let it spontaneously combustion, and then ignite the corpse oil to form a fire. ”

"Maybe you're right! By the way, I forgot to ask you, where is the exit of this escape route? ”

"The exit is on the mountainside not far from the Zhijun and their shed, more than 5 meters above the ground, and the entrance to the cave is all grass, which is quite hidden."

"Are there any other forks in the tunnel?"

"There are still 3 forks in the road below, and I didn't go up to see them."

"Okay, then tomorrow you can figure out those 3 forks and find out where they lead, since there is a passage below, it means that there are other spaces waiting for us to discover."

After dinner, Professor Chen was engrossed in looking at the photos taken by Ma Kai on the computer when he was interrupted by a ringtone. After looking at the name displayed on the screen, he connected the phone, and before he could speak, the other end of the phone said first: "Professor Chen, pay attention to ghosts tonight." ”

"Oh, there's movement again?"

"Yes, the WeChat content he sent half an hour ago was intercepted by us, and the content was written with the words 'The hole has been opened, and the blood jade edict is bound to be obtained'."

"Blood Jade Edict? It's a legendary thing, does it really exist? ”

"It's not clear about this, it seems that they are prepared, you can pretend that you can't see anything tonight, let him go in and do whatever he wants, and when our people go in and take all the stolen goods, you can go in if you want to."

"Then what do you arrange here?"

"Don't worry, it's been arranged, and Team Wu is still in charge."

"Okay, just a hint, the burial pit inside is burning, and it doesn't smell good, so you can let your comrades wear thick masks to go in."

"Thank you."

After Professor Chen hung up the phone, he hurriedly asked Ma Kai to call Zhang Gong and all the others, and quietly shared the content of Sun Ju's phone call just now.

The problem of the inner ghost, everyone had already been mentally prepared, so there was no big reaction, but as soon as they heard the blood jade edict, the eyes of several old guys immediately showed unusual excitement.

The Blood Jade Edict is something that has been legendary in the archaeological and literary circles, and it is said to be the proud work of a well-known Zongbo in the Eastern Zhou Dynasty. It is made of five pieces of jade about 35 cm long and 19 cm wide, and it is engraved with the location and method of burial of large and small tombs of the previous dynasty. Because the information on these jades is invaluable, it is inevitable that people will not be peeping, so he hid these 5 pieces of jade in the female corpses that had just been buried, buried them in the ground together, and then dug them out and replaced them in fresh female corpses after a year to continue to preserve. As the uncle had a premonition that his death was approaching, he killed five unmarried women in a mysterious place, put five pieces of jade in their bodies, and buried them in five different directions, and then found a place for himself to commit suicide, and since then the five pieces of jade have become legends. After hundreds of years, the 5 pieces of jade were rumored to be even more evil, saying that whoever got those blood jade could get the world, which became the dream of generations of emperors, and it was slowly rumored to become an edict.
