Not only did Cao Yu not understand, but the others also didn't understand, and they all looked at Wu Liang with puzzled expressions.

"Brother Anmin, don't be impatient."

Wu Liang just smiled indifferently, and while continuing to do something, he said to the soldiers, "I'll only do it once, pay attention to it clearly, and you will do this kind of thing in a while." ”

This time, Wu Liang passed a rope through the small hole reserved on the head of the Luoyang shovel, tied several strong dead knots, and then inserted the Luoyang shovel vertically along the small hole dug before.

Then a stone was brought from the side and slammed it on the handle several times, causing it to sink about 30 centimeters again.

Then he pulled the rope upward, and lifted the U-shaped shovel head out of the soil and rotated it 90 degrees, and then smashed and lifted again, and then smashed and lifted again, and after a week of rotation, the shovel head brought up a tube of soil when it was raised this time.

In just a short period of time, the small hole had penetrated nearly 60 centimeters.

"Do you see clearly?"

Wu Liang looked back at several soldiers.

"See clearly."

The soldiers nodded blankly.

"Then come and work."

Wu Liang clapped his hands and decisively handed over the Luoyang shovel to them.

This operation is not too cumbersome, several soldiers according to the gourd to draw scoops, learning quite like that, a short time has fully mastered the use of Luoyang shovel skills, mutual cooperation efficiency is naturally much faster.

After a few times, the wooden handle attached to the back of the Luoyang shovel was no longer long enough.

However, Wu Liang had already prepared more wooden handles, and taught them how to connect the wooden handles and continue to dig down.

However, seeing that a few soldiers were doing happily, Cao Yu became more and more puzzled in his heart, and finally couldn't help asking: "Brother Xian, what does this mean?" ”

"Brother Anmin, how deep do you see they are digging now?"

Wu Liang asked with a smile.

Cao Yu glanced at the wooden handle behind the Luoyang shovel and said, "It's almost more than a zhang." ”

"How long does it take to dig a one-foot deep hole?"

Wu Liang asked again.

"If ten people do it together, it will take about half a day."

Cao Yu said in a deep voice.

"And what about my pit?"

Wu Liang asked again.

"It's been about a moment......"

Cao Yu already understood what Wu Liang wanted to express, but he still had other doubts in his heart, and then said, "But this pit is so narrow and small that we can't not enter it, but we can't see the situation at the bottom of the cave, so what's the use of digging it?" ”

"Brother Anmin is too worried, others may not be able to see it, but my brother can see it."

Wu Liang said with a smile.

People of later generations should know that Luoyang shovel hole is not for people to lie on the hole to view, the key to really judging whether there is an ancient tomb underground, in fact, is the soil brought up by the tube.

How to distinguish the soil quality and determine whether there are ancient tombs underground is also a compulsory subject for archaeology majors.

First of all, soil is mainly divided into two categories: dead soil and living soil.

Dead soil is an ancient surface layer that has not been touched by human activity before, such as sedimentary soil, alluvial soil, clay, and sandy soil, with different thicknesses and colors.

Living soil refers to the soil that has been formed by human activities and contains relics, such as cultivated soil, rammed soil, road soil, burnt soil, ash soil, flower soil, silt soil, and fluttering soil.

When looking for tombs, the main exploration is the rammed earth layer and large flower soil, as well as the unique soil layers of ancient tombs, such as "green plaster mud" and "white plaster mud" used to fill the tomb wall.

In addition, the rammed earth layer and large flower soil of the ancient tombs of different periods are also different.

Like the ancient tombs of the Spring and Autumn Period and the early Warring States Period, red reticulated soil is often used to backfill and then rammed layer by layer, and under normal circumstances, the color of the rammed earth layer of the Spring and Autumn Tombs is slightly lighter, while the ancient tombs of the Warring States Period are slightly darker.

The ancient tombs in the late Warring States period began to be backfilled with red reticulated clay mixed with loess, and compacted in layers.

The early and middle tombs of the Western Han Dynasty are often used to be backfilled with pure loess, this kind of loess has good viscosity, and the previous Tufuzi who did the yellow mud business is looking for this kind of mud to dig, and the ancient tomb can be dug out with a dig.

When he arrived at the tomb in the late Western Han Dynasty, when he added the tomb, he brought a kind of yellow sand mud from other places to fill the soil.

The tomb of the Eastern Han Dynasty is similar to the tomb of the Western Han Dynasty, but the yellow sand mud is no longer used to fill the soil, but the rammed earth is not as tight as the tomb of the Western Han Dynasty, a little loose, commonly known as "bubble board".

As for the tomb in the back, the current Wu Liang definitely has no chance to steal it, so don't mention it.

In short, this knowledge of viewing the earth and the tomb is said to be these at best, and there are all kinds of different details at the deepest, if there is no systematic study and long-term experience accumulation, it is really not something that ordinary people can master.

Because of this, Wu Liang didn't mind that Luoyang Shovel was stolen from someone to learn, it was just a superficial thing, and the real core technology existed in his heart.

"Could it be that Brother Xian's eyes have another mystery?"

As soon as he heard this, Cao Yu immediately showed surprise on his face, and leaned over to look at Wu Liang's eyes carefully.

"This is the secret of the ancestors, called the technique of 'dividing gold and fixing acupoints', and if you say more, you can't say anything."

Wu Liang pulled Cao Yu's hand away and decisively turned on the tricky mode again.

There are still many powerful words for him to use Zhang Guan Li Dai in later novels, and it is not an exaggeration to say that they are inexhaustible.

Of course, Wu Liang's purpose is to better protect himself.

Don't teach all your abilities at any time, this is the truth he learned from a fable about cats and tigers, as the master of the tiger, the cat is precisely because he left a hand and did not teach the tiger the ability to climb trees, so that the tiger survived when he crossed the river and demolished the bridge.

However, at the same time as he said this, a rather philosophical question suddenly jumped out of Wu Liang's mind:

If you continue to play like this, will there be a gold-touching captain who is good at dividing gold and fixing points in history, or will there be him Wu Youcai first?

……

After a while.

Several soldiers had already dug the pit to a depth of more than 5 meters.

Wu Liang "inadvertently" glanced at the excavated soil, and found that it was still dead soil after digging so deep, so he came to the pit dug by the Luoyang shovel and looked at it, and then said in a firm tone, "Let's go, there is no need to dig here, there is no tomb below." ”

Ancient tombs like this, guarded by tomb keepers, are generally not small in scale.

Therefore, as long as a hole is drilled and no suspicious soil is found, you can immediately change the place, and there is no need for the "plum blossom point" tomb exploration method to carry out a small area of exploration for the time being.

"Sure so soon? Brother Xian's technique of 'dividing gold and fixing acupoints' is so magical? ”

Cao Yu was pleasantly surprised, this is indeed much faster than the previous efficiency, and it only takes a quarter of an hour to calculate before and after, and it also eliminates the process of filling the pit in order to hide people's eyes and ears when he was in Dangshan before.

If this "dividing the money and fixing the hole" is really useful, they will definitely get twice the result with half the effort in the future!

Bai Jingjing's eyes showed a subtle look of worry......

At the same time as it.

In a high forest outside the Valley of No Return, a man hidden in the canopy of trees looked at it for a while, and finally said to the people below: "Jingjing is not dead! It turned out that she was caught by another group of people, no wonder she couldn't find a trace a few days ago, but at this time she put her clothes on the back of her body, which is to tell us that this group of people is not simple, and tell us not to act rashly. ”
