Yan Hua's words were convincing, and Professor Hao's eyes gradually lit up.

The two of them studied the wall, how to open its mechanism.

When you go back and forth to study, you will inevitably be mixed with the corpse under your feet.

These corpses are like sleeping people, and when they are mixed up, it is like accidentally kicking a living person.

Thousands of years have passed, but the corpses on the ground are forever frozen at the moment of their death.

What an amazing thing it is.

Professor Hao was sighing, but he suddenly paused.

He looked down at the corpses that could be found everywhere at his feet, and a bold idea formed in his mind.

Professor Hao turned his head to look at Yan Hua again, and happened to meet her gaze.

The two smiled tacitly, mysteriously.

Qin Shuya then poked a corpse next to her with a Luoyang shovel, and the words she said were more like affirmation to the two of them.

"These corpses should have died from inhaling a large amount of poisonous gas, which should be a kind of antiseptic that was studied in ancient times."

Yan Hua and Professor Hao looked at each other again, and she also spoke: "This preservative is very toxic and hallucinent, but anaerobic, the presence of a large amount of oxygen will destroy its components, so that it loses the effect of a preservative, and only hallucinogenic poison remains." ”

Professor Hao nodded, lowered his eyes and looked at the corpse on the ground again: "These tomb robbers probably also discovered that this layer is the only way to enter the tomb, so they gathered here to find the entrance." ”

Yan Hua had already lowered her head and revised her map: "So, the Outer Xian Gate actually leads directly here, and then enter the second floor where we are currently located, and if you find the mechanism here, you can continue to go deep into the Inner Xian Gate." ”

Professor Hao nodded: "This makes sense why they gathered here, instead of going straight to the Neixian Gate." ”

When they said this, Yan Hua and Professor Hao both showed expressions of sighing.

The craftsmen at the beginning were so powerful, how did such a huge project be completed?

It's like the Great Wall, no one can imagine how it was piled up in such an era, and it is even more difficult to imagine where the people who were recruited came from so much strength?

After the exclamation, another question will be pondered.

How much flesh and blood is buried under the Great Wall?

How many innocent souls are buried in the tomb of King Qin?

It's written in the literature that it's millions, so what kind of concept is that?

With 3,000 teachers and students in a provincial key high school (all of them are strong laborers), only such a tomb of King Qin needs at least 334 provincial key high schools of the same scale to fill in their lives.

It's terrifying to think about.

And the first emperor at that time was obsessed with immortal dao and wanted to ask for immortality.

At that time, alchemy was very popular.

It is not impossible to refine such a highly toxic preservative by accident.

Now that such a fresh corpse is lying all over the ground, there is no need to question and quibble about its actual efficacy.

Anaerobic preservatives, how suitable for burial use?

Just put that preservative in the coffin, let it release slowly, and bury the coffin.

The underground confined tomb is an excellent anaerobic environment, and as long as it has not been visited by tomb robbers, the environment in the tomb is almost immutable.

"So, it's likely that this embalming was extracted from corpses."

Yan Hua's words shocked Professor Hao for a long time.

In an instant, he also thought of many local rumors.

- When the ancestral grave was moved, when the coffin that was buried was rediscovered, it was as if it had just been buried.

The lid of the coffin was opened, and the old man lying inside had a ruddy face, as if he had fallen asleep.

But in a matter of seconds of exposure to the air, the corpse was disfigured beyond recognition at a speed visible to the naked eye, and in the end, all that was left was a broken skeleton or even a pile of flying ashes.

In ancient times, such a cemetery was called Feng Shui Treasure Land, which has an excellent effect on raising corpses and can protect the remains of ancestors from decaying for thousands of years.

In fact, it is an anaerobic environment and the earthly atmosphere that the ancients emphasized to nourish the corpse.

But the corpse can't be in direct contact with the earth's qi, and direct contact will deceive the corpse and raise all kinds of large and small zongzi.

Professor Hao was involved in this kind of research when he was younger.

Experiments have proved that in an anaerobic environment, the so-called earth qi reacts wonderfully with the microflora on the corpse, producing a substance that can be embalmed.

However, this substance is very unstable and will be destroyed by contact with oxygen.

At that time, the results of the research could only be used to support why the corpse was buried in the ground for thousands of years without decaying, and to unravel its mystery, but it was not thought of what other uses it could have.

I don't think the ancients would have discovered this secret long ago and applied it to the imperial tombs.

It can not only be used for embalming and keeping the emperor's body intact, but also used to resist the invasion of foreign enemies and prevent the invasion of tomb robbers.

It's just that the ancients cherished the habit of broomsticks, and this method has not been handed down.

Professor Hao rubbed his hands excitedly: "This is a new discovery, write it down, this must be written down carefully." ”

Professor Hao was excited, but Yan Hua couldn't get excited, she said an extremely cruel guess and splashed Professor Hao's head and face with ice water.

Therefore, it is likely that the craftsmen who were buried alive or killed in pits were the raw materials of this preservative. Their location is the source of this highly toxic preservative. ”

When Yan Hua's words fell, Professor Hao couldn't laugh anymore.

Professor Hao's silence made the corridor that was still lively just now instantly dead, and it seemed a little ghostly.

The staff members who followed the three of them glanced around a few times.

These corpses are all lying directly on the ground, are they considered to be in direct contact with the earth's qi?

So, if they have been lying here for so many years, will they have become zongzi a long time ago?

The more they thought about it, the more panicked they became, and every time they dodged a corpse, they were terrified, and they were afraid that the corpse that was motionless on the ground one moment would jump up and pounce on them the next moment.

Such an atmosphere is as if the air with low oxygen is full of tension.

One of the staff members in the back couldn't stand it anymore, and he was almost scared to pee.

So he asked with a trembling voice: "Professor, you have said so much, will these corpses become zongzi?" ”

Professor Hao shook his head and replied in the affirmative: "No." ”

"Really, really?"

Another staff member confirmed with a trembling voice.

Professor Hao replied in the affirmative: "No." ”

Just these two words can't seem to soothe everyone's trembling little hearts.

Professor Hao wanted to make a supplement and reassure them.

At this time, Yan Hua heard Professor Hao's slight gasp, it should be the low oxygen supply of the oxygen cylinder, which could not support him to speak for a long time.

In order to relieve Professor Hao's pressure, Yan Hua spoke very intimately again to help him interpret those two words.

"Although the oxygen content here is not high, it is not a completely enclosed oxygen-free space."

"So, these corpses are actually failures."

Everyone: "How so?!" ”
