Chapter 1491 (1/2)

Although Chen Hui has a certain understanding of the world, he still doesn't know enough about it. For example, he doesn't know about the funeral customs at this time.

The green emperor, as well as several witches and warriors, could not help nodding after seeing these civilians splashing water in Prince Chang's tomb and the situation after splashing water.

Obviously, the construction of Prince Chang's tomb was very successful.

From this, Chen Hui roughly thought of the standard for building tombs at this time. Besides the size and depth of tombs, the most important standard is waterproof.

After thinking of this, Chen Hui could not help but carefully observe the tomb built for Prince Chang.

In other words, Chen Hui wanted to make clear that the tomb built for Prince Chang was a kind of tomb excavated deep underground, and how the drainage system was constructed without any buildings.

After careful observation, Chen Hui can see some clues. Although the tomb is like this, it is not like this.

At this time, the color of several circles of soil around the tomb is slightly different.

It can be seen that this tomb is actually much bigger than what Chen Hui saw at this time. It is divided into many circles, but several outer rings have been backfilled at this time. I don't know the position of the backfilled outer ring and what kind of treatment has been done, which leads to the strong water absorption function.

Now that the outer ring of the tomb has been backfilled, Chen Hui naturally can't open it up for inspection.

However, around the tomb of Prince Chang, there are mounds for backfilling.

The mound is divided into three piles with different colors.

Just as Chen Hui thought about the use of the three piles of backfill soil of different colors, a wizard went over and reached out to twist the backfill soil.

After seeing this scene, Chen Hui went over, squeezed some soil in his hand, gently twisted it, and asked the wizard in a low voice why he needed three kinds of backfill soil.

The three backfilled mounds are located in three different directions, and the colors are also different. At a glance, we can see that they are used differently.

The wizard gave a simple answer to Chen Hui's question in a low voice. This kind of soil with some gray color was transported from other places. There is no such soil here.

And this pile of soil is the soil that Chen Hui is twisting. After twisting, the fragments of the soil are very fine, which makes people feel very smooth, a bit like cement or talc.

But it's definitely not cement or talc.

After the wizard's explanation, Chen Hui understood that this kind of soil would be covered and tamped immediately after Prince Chang's coffin was buried.

The compacted soil has strong waterproof function.

Judging from the meaning expressed by the wizard, this kind of soil can resist 78% even though it is not 100% waterproof after tamping.

The upper layer of soil is also transported from other places, and its water absorption is particularly strong.

The first layer of water-proof soil to cover the coffin will not appear flat after tamping, but in the form of radian, similar to the bottom of the pot.

Then above is this layer of water conductivity better soil!

On the top is the common soil, which is also excavated from the tomb of Prince Chang. This kind of soil should be used to seal the top.
