Of course, Yuebai had heard a little about this, but the only thing he didn't know was how this kind of smoke and void situation happened.

"Smoke is more difficult to form than a mirage..."

Xu Li said: "There is a record in our Taoist sect that there are only two possibilities for this kind of situation to be formed, one is that the ghost uses ghost spiritual power or demon power to create, such as the illusion demon of our fox demon, that is the simplest virtual trace effect!" ”

"What about the second one?"

Yuebai lit a cigarette and asked, "How did I hear that this kind of large-scale void in front of us is not an ordinary ghost that can be created?" ”

"You're right!"

Xu Li nodded and continued: "The second situation is not an ordinary demonic power, as far as I know, it can cause such a real and large-scale void trace, except for rare monsters, only the legendary Dao Immortals are capable of doing it. ”

"Dao Immortal? Is there really a situation in this world where a Taoist cultivates to become an immortal? ”

"Why don't you say it's a monster?"

"Hehe, I'm not used to thinking about things for the better..."

Yuebai smiled slightly, took a deep breath, and said: "Forget it, whether this is a masterpiece of Dao Immortals or not, in short, we have no choice, but it will not work in the past!" ”

"Huh? Your conscious forces have detected clues? ”

"It's not a clue, it's a fat man!"

Yuebai threw the cigarette butt on the ground and said, "The breath of a fat man appears in my perception, and the direction that my father looked at back then must be the location of this void." ”

"In that case, let's go down!"

Xu Li was also a little excited, she put the submachine gun in her hand on her back, then took out a rope and tied a pig's trotter buckle to the trunk of a tree beside her, and then, with the help of this rope, they went straight down and fell into the valley where the virtual trace was.

Descending to the valley, Yuebai once again used the power of consciousness to sense the position of the fat man, and then pointed in a direction and walked with Xu Li.

The outer perimeter of the valley was full of weeds, and although it was not as difficult to walk as the woods, these weeds still gave the two of them an uncomfortable feeling.

After walking cautiously for half an hour, the lawn house that I had seen standing on the cliff slope was in front of me.

But when I got closer, I found that these houses had really become ruins, especially the ones outside, which had long since collapsed and were not presentable, not to mention the courtyard walls, and even those houses had fallen into piles of grass, and there was no way to repair them anymore!

Truth be told, these stub houses are a thing of the past in this day and age, but if you go to a remote mountainous area or a natural village that is being developed, you can also see this kind of mud house.

For example, in a certain county in Hebei Province, there are still traces of straw houses in many villages in that county.

However, the straw houses that can still be seen today are not really made of mud, because there are great safety risks in building houses only from mud.

Therefore, the billet houses that can be seen today are only in the seventies and eighties, when the outer layer of the adobe walls was pasted with green bricks, or reinforced with wood, half brick and half mud new mud houses!

But in any case, the only thing that this straw house can represent is the poor life in the early years, and the traces of historical evolution, and its existence shows that human beings have renovated or regressed and progressed in their living choices!

Although mud houses can be warm in winter and cool in summer, they are far less comfortable and sturdy than modern brick houses.

However, in the ruins of these dilapidated mud houses in front of her now, there is one thing that Yuebai really can't figure out.

Because in his memory, in the seventies and eighties, or earlier, no one lived in this kind of mud brick house around Harbin anymore, that is, during that period, the poor people around Harbin could also buy green bricks to build houses.

"The time of the existence of this village... It's not just the seventies! ”

Yuebai felt that only earlier and the explanation of the people's income could make sense of this, but he still motioned for Xu Li to stop at this time, and then grabbed a piece of extremely hard yellow clay nearby.

This piece of yellow clay should be a small part of a certain mud brick, and its hardness is simply not mentioned in Yuebai's hands.

However, when Yuebai kneaded this piece of yellow mud into soil powder with his fingers, in addition to the dry soil of yellow mud in his hands, most of the remaining half was actually all plant dust!

"It's strange, how can there be so much wheat straw in this brick?"

Yuebai knew that in the early years, in order to strengthen the toughness of the mud bricks and the effect of cold and heat insulation, a certain proportion of straw or wheat stalks would be added to the mud.

However, if too much of these plant crumbs are added, it will have the opposite effect on the hardness of the mud bricks, and may even cause dangerous disadvantages in the problem of fire protection.

However, the addition of broken wheat stalks to the mud bricks here clearly shows that there is no such idea, because it is unlikely that anyone who can think of these problems will add so many broken wheat stalks.

"Is it because there is less mud here, and the proportion of plant crumbling is deliberately increased?"

Xu Li guessed: "I heard that in many places, there is even a lack of yellow mud, and it would be good for those poor people to have a house to live in, so why not care about fire prevention!" ”

"Come on, this is not a country of mountains and rocks, how can there be a reason that there is not enough mud!"

Yuebai rolled her eyes, and said in her heart: Even if there is not much mud in the local area, it can't even ignore safety, and besides, if this plant is broken and added too much, then the firmness is a big problem, and it can't keep the house built the day before yesterday, and it collapsed in a blink of an eye, and in that case, why build a house? Wouldn't it be easier to build a shack directly out of grass to save people and materials?

Indeed, Yuebai is not wrong to think so.

You know, if the local mud is not enough, then reduce the length and area of the courtyard wall by one foot, this is not enough to enrich the yellow mud to strengthen the main house, after all, the main house is safe, then the rest is not very important.

Moreover, since there is a place where wheat straw can be grown, it means that this is not a rocky area, so it is impossible to have a shortage of mud.

Also, in this ruin, which is almost invisible at a glance, all the places after the collapse of the houses are all shadows of this yellow mud brick, which also shows that the building materials here are mainly inexhaustible yellow mud, otherwise, it would not be possible to be all the ruins of yellow mud houses.

"And what do you think?"

Xu Li heard Yuebai's words reasonable, so she asked her husband, what explanation do you have for this phenomenon? Could it be that there is any other meaning to the excessive wheat straw crushing in this mud brick?

"Uh... I can't say it right now! ”

Yuebai frowned, slapped the loess and plants in his hand, and said, "But I think that if the phenomenon here is too unconventional, it must have a very important purpose, at least, it has now shown the difference between this place and other environments." ”

"Cut, you're, fools know it!"

Xu Li rolled her eyes, looked at the time, and then said: "I advise you to hurry up, our work is not short, if we can't find the fat man and leave here before dawn, then we may disappear with this void!" ”
