C78 (1/2)

”This is the place …”

Fang Zishu took a deep breath, then beckoned to the police officer, ”Officer, take out the Luoyang Shovel and try out the situation below!”

Although he had used many methods to determine the possible location of the cave, in order to be safe, he still intended to use Luoyang shovelful to test it.

Hearing Fang Zi Shu's words, the police officer nodded and then took off his backpack. After he took out the Luoyang shovel, he did not start work immediately but instead took out a lot of things from his backpack.

With Qi Sanpang's help, the cop now placed the tough wooden stick on the right side of the Luoyang Shovel, and then connected it with a special white line on the edge of the wooden pole.

The white line was transparent and looked very much like the fishing line used in the coastal areas. However, the materials used were very different.

The texture of the white line looked soft, but it was actually very strong and elongated. After putting it on the 'wooden pole', the Luoyang Shovel could easily penetrate several tens of meters into the ground.

This was not all. When Luo Yang's shovel was mentioned, the strength of the white line would cause the grooves on the 'wooden stick' to be filled with soil.

In this way, the prescription would be able to use the skills passed down through the ancestors of the field officer of the Gold Forging School to 'smell', 'ask', and 'cut' the soil that was brought out. Through this method, he was able to determine whether the soil that existed underground was the mature soil that had been touched by living people, or was a raw soil that already existed.

After the note had finished loading the Luoyang Shovel, it immediately stood up.

Then he stood up straight, legs apart, holding the pole with both hands in front of his chest, shoveling his head onto the ground between his toes, and poking down hard vertically.

When he opened his mouth to the end, he continuously rotated the shovel head and spanked it in all four directions, maintaining the cylindrical shape of the hole.

Dig the soil from the cutting edge, pry it apart longitudinally to see the section. When looking at the earth, you can't shovel back. The shovel back is to continuously hit the ground two or three times before you pick up the shovel. In fact, there were many kinds of soil underground. The teachers divided the soil into two categories: Dead soil, live soil and mature soil.

Generally speaking, ten thousand years ago, the dead soil could not be pulled out and the shovel stuck in the hole. Drilling one side down, hole semicircle, two sides down, hole ellipse.

Only by shoveling on all four sides would the hole be round.

The hole had to be made to straighten out.

It was unbending, it was straight and unerring.

It is not very easy to punch a vertical hole. For tools, the shovel head should be straight, and the pole should be straight.

Otherwise, easy to punch the hole, even punch the hole small belly, is not famous.

Just as Luoyang shoveled a few meters into the ground, the cop stopped moving. His face revealed an excited expression, ”Zi Shu, you're right. There's something underneath. I could feel it when I was kneading the ground.”

The cop's words made Fang Zishu even more excited, ”Bring Luoyang up, let me see the composition of the soil below.”
