Three o'clock in the afternoon.

After determining the scope of exploration, Kong Jianwen immediately divided the archaeological team into five teams, each team of 5-6 people, and after each assigned a small exploration area, everyone began to work.

Of course, Chen Han formed an exploration team with Su Sa, Zhuang Yunpeng, Zhang Jianbo, Lin Ya and Wang Weida.

The previous experience of working in a research group with them was quite harmonious, and Kong Jianwen also hoped that these young people could get closer to each other.

Wearing a big straw hat, wearing labor protection gloves, and carrying a bunch of metal sticks in their hands, Chen Han and the others began to explore in the wasteland in the southeast corner of the construction site according to Kong Jianwen's requirements.

Doing on-site exploration is actually not as lofty as the public thinks.

In fact, it is a very physically demanding job.

Half-squatting on the ground, Chen Han took out a shovel head from his backpack, picked two metal sticks at random, and began to assemble them.

The name of this tool may be slightly unfamiliar to non-archaeological professionals.

But when it comes to its other name, Luoyang Shovel, it is like thunder.

Luoyang shovel is a very Chinese archaeological drilling tool.

And interestingly, the earliest widespread use of this thing was by tomb robbers.

This is something developed by ancient Chinese tomb robbers, but it is really easy to use, so it was quickly favored by Chinese archaeologists.

Up to now, learning to use the Luoyang shovel to identify the soil quality has been the basic skill of every archaeologist.

The Luoyang shovel is actually very simple in composition, which is a shovel head and a round metal shovel body.

And the shovel body can be extended, the length of each metal rod is about one meter, two are two meters together, and three are three meters.

The connection method is also very simple, just like twisting the screws, just connect and tighten it.

As for the specific length of the connection, it is generally used according to the exploration requirements of the site.

Chen Han first connected two sections, and then installed a handle, a T-shaped Luoyang shovel, which was assembled in a minute or two.

"What do you say, senior brothers and sisters come first?" Chen Han took the Luoyang shovel and asked casually.

The rest of the group looked at each other and shook their heads.

"Senior Brother Chen, you can get the first shovel." Su Sa squinted and smiled.

When the excavation work was carried out at the Lajia site before, because the site of the site had been determined, and the local archaeological institute had prepared the exploration party, there was basically no need for Chen Han and them to carry out exploration work.

Just go straight to the ground and excavate.

However, this time the Phoenix Mountain tomb group is different, it is an exploration-based project.

Chen Han is a newcomer, he is really new, and everyone must give him more opportunities to practice.

He didn't have anything to be humble, and after nodding, he randomly chose a place that looked a little dry and cracked, held the probe shovel, took a figure-eight step, and went down vertically.

The sharp shovel head suddenly sank into the dirt, about 3-4 centimeters deeper.

Immediately, Chen Han twisted the shovel handle, and then pulled it out hard, and a 3-4 cm cylindrical clod of soil was brought out on the shovel head.

Lifting the shovel head and taking the clod of soil off the shovel, Chen Han looked at it casually and said, "Well, at first glance, it looks like modern old soil." ”

Zhuang Yunpeng rolled his eyes, and said with a smile: "You are not talking nonsense, the soil layer three centimeters above the ground must be a modern soil layer, far away from the cultural layer." ”

Chen Han nodded with a serious face, and continued to follow the hole that was punched, and hit another shovel vertically downward, and the three-centimeter clod of soil was hit up again.

It was still very ordinary gray silt, but Chen Han still solemnly put it next to the clods of soil that had been punched out in the previous shovel and placed them in order.

In this way, it is necessary to distinguish the changes in the soil layer and to have an intuitive judgment of the depth of the current lay.

The movements in Chen Han's hands did not stop, and he hit shovel after shovel.

Cylindrical clods of earth were also dug up from the ground by him.

The first five shovels were shoveled, and the unearthed soil layer basically did not change, and it was all gray silt.

However, by the sixth shovel, the soil layer began to change a little, and some red and yellow particles began to be mixed in.

The other people who had been watching him explore the cave also looked serious.

Zhuang Yunpeng looked at Chen Han's standard burrowing posture with interest, and said expectantly: "You say, will we have a good start today, and find a tomb in the first cave?" ”

"Who knows~" Lin Ya shrugged: "Last year, I went to Xi'an with Mr. Liu for field exploration. ”

"You don't know, the underground cultural layer in Xi'an is called a rich."

"As soon as the shovel went down, starting from a depth of two meters, it brought out porcelain shards, pottery shards, and jade shards one after another."

"It's a pity that it's just an exploration and a conservation of the tombs, but it can't be excavated."

Lin Ya smashed her mouth, looking strange and pityful.

They were chatting on the side, and the movements of Chen Han's hands did not slow down, and they were still digging steadily one shovel after another.

Soon, he hit almost twenty shovels, but it was all normal solid soil, and he didn't see any signs of flowering soil.

Flower soil, that is, natural soil is excavated and backfilled for a second time, which disrupts the original level and color boundary, and becomes a soil layer that combines a variety of soil layers.

Even if the soil layer is old, it will not mix into a single color and will remain in the same state as when it was backfilled.

Generally speaking, if flower soil is found, it means that there have been traces of excavation and backfill underneath, and there is a high probability that there is a tomb.

That's how the tomb robbers came to find the tomb.

This is also the reason why the Luoyang shovel is called a necessary tool for tomb robbery, without the Luoyang shovel, the first step of tomb robbery "to find the tomb" can not be carried out.

Even if there is a saying of feng shui treasure land in ancient times, but a feng shui treasure land, the scope is also very large.

There may indeed be very powerful tomb robbers, looking through ancient books, through some ancient feng shui theories, to find some feng shui treasures that are likely to become the burial sites of the ancients.

But if there is no Luoyang shovel, it is basically impossible to find the specific location of the tomb with the help of feng shui.

Unless he can directly dig the entire "Feng Shui Treasure Land" three feet into the ground and sweep it with a carpet.

It's just that how could a tomb robber dare to make such a big move!

Therefore, it has to be the Luoyang shovel, the best partner for tomb robbers and archaeologists.

"Whoa, whoa."

After digging out for more than twenty shovels, even Chen Han, who was strong, was a little tired and panting.

Archaeological exploration is really individual work, and the further down you go, the tighter and more laborious the soil layer becomes.

Zhuang Yunpeng hurriedly stepped forward and took the Luoyang shovel from Chen Han's hand: "Come for me, you rest first." ”

Tombs that are often three to seven or eight meters deep, or even more than ten meters deep, have to be shoveled at least one or two hundred times to find a little trace and clue.

It is obviously impossible to dig the cave by one person.

Why are tomb robbers all committed by gangs, isn't it because they can't do this work alone, otherwise it won't be fragrant to eat alone?

In this way, Chen Han took turns to shovel a dozen shovels per person, and a dozen shovels went down, and the cave was getting deeper and deeper.

After playing three or four meters deep, Chen Han, who had changed several rounds and played the hole again, was still mechanically repeating the actions of probing, twisting, and pulling out.

Until, Su Sa's exclamation broke his boring and repetitive movements.

"Hey, is this flower soil?"
