the whole world joins in the jubilation! It's raining! Collect your clothes!!!

------------------

Tu Qingqing nodded.

Wei Xiaobei pulled Tu Qingqing's left hand, then his heart moved, and they disappeared in situ.

When they reappeared, they had come to the space created by Wei Xiaobei.

Er, it should be noted that the space created by Wei Xiaobei is really narrow.

Wei Xiaobei naturally didn't feel much when he came in, but Tu Qingqing felt a burst of depression after he was brought in by Wei Xiaobei.

At this time, the space is composed of a wet mud ball and some air. Its overall diameter is only 20 meters, and there is a thin transparent barrier in its outermost part.

In other words, Tu Qingqing stands on the mud ball, and the sky is only ten meters high.

Not to mention raising your hand can touch the sky, but this space is really small, which is an indisputable fact.

Wei Xiaobei's initial excitement dispersed and responded. He blushed and coughed twice. He said to Tu Qingqing, who was a little depressed: "we haven't built here yet. Let's go out?"

What Wei Xiaobei didn't expect was that Tu Qingqing, although a little depressed, looked around curiously, and then said something that surprised Wei Xiaobei.

"My husband is really good. He can stand on his own. He is on a par with Tu Shan, the ancestor of Qingqing."

What?

Wei Xiaobei was naturally not a fool. After a little surprise, he reacted.

Tu Qingqing's Tu Shan family is naturally the ancestor of Qingqiu who married Dayu.

According to Tu Qingqing, Qingqiu is also independent of the gray world. However, due to the lack of connection between green and yellow in some countries, the distance between Qingqiu and the gray world is getting closer and closer.

Speaking of this, Tu Qingqing's eyes seemed to twinkle when he looked at Wei Xiaobei.

"You and I are husband and wife. If you have anything to say, just say it."

Wei Xiaobei can guess what Tu Qingqing wants to say, but he still needs to confirm.

Sure enough, Wei Xiaobei guessed Tu Qingqing's mind.

To put it bluntly, I just want Wei Xiaobei to help in the country of Qingqiu.

The main reason for this is that the space of the green hill country is constantly affected by the gray world. According to this rhythm, I'm afraid it won't be long before the green hill country will break away from the identity of independent space and become one with the gray world.

And what is the grey world like now?

Even Wei Xiaobei knows one or two.

Those so-called abandoned places are not for fun.

Once the green hill country and the gray world are integrated into one, the final end is to dissipate the aura and become an abandoned place.

After listening to Tu Qingqing's words, Wei Xiaobei thought for a moment, calculated some and came to a conclusion.

In my understanding of the mystery of space, it will take at least five years to separate the green hill country from the gray world!

The question is, can the country of Qingqiu wait five years?

"Only five years? Husband, you're great!"

Tu Qingqing was pleasantly surprised after hearing Wei Xiaobei's answer.

Well, in fact, it will take at least more than 50 years for the green hill country and the gray world to become one!

Of course, in the eyes of Qingqiu people, fifty years is very short.

After receiving Wei Xiaobei's promise, Tu Qingqing did not continue to disturb Wei Xiaobei, but stepped on the cloud and returned to Weijia island.

As the mother of Weijia Island, Tu Qingqing has a lot to deal with, especially when Wei Xiaobei is the shopkeeper.

After Tu Qingqing left, Wei Xiaobei had a little aftertaste of what had happened in the cave before, forced himself to calm down and focus on the gray boundary stone.

After the successful creation of the narrow space, the blue light at the center of the gray boundary stone has disappeared, and the whole gray boundary stone is only two fifths of the previous volume. Moreover, with the passage of time, the gray boundary stone is also gradually disintegrating, and small gravel is constantly stripped off its surface.

It is not surprising that the minimum volume of the grey boundary stone can be maintained by the blue light. Once the blue light is controlled by Wei Xiaobei and transformed into the starting point of creating space, the remaining grey boundary stone has no attached core.

Of course, if the gray boundary stone is allowed to disintegrate into a pile of space gravel, the loss of weixiaobei is not small.

You know, although these space gravel can also be used to refine the magic weapon of storage, it has lost the advantage of expanding space.

The next moment, Wei Xiaobei's mind sank and entered the space he created.

The space is small, but it's not small.

The whole is a sphere with a diameter of about 30 meters. The diameter of the inner mud ball is 10 meters. A circle of air mixed with water vapor and other gases is wrapped outside the mud ball.

Well, if you have to describe it, it is probably a little similar to the earth.

In short, if weixiaobei needs it, it can store more than 2000 cubic meters of material in this space.

Of course, Wei Xiaobei created such a space, not just to be used as a storage magic weapon.

Wei Xiaobei is observing the situation of this space from inside to outside.

After checking his breath, Wei Xiaobei breathed a sigh of relief, which was more in line with his expectation.

The whole space is in good condition, but the space volume is too small, which makes the whole space in a state of slow operation.

In short, this is slightly similar to the situation in the storage ring.

Of course, in essence, the two are different.

The space in the storage ring is a completely solidified space. The reason why the storage space can exist is its solidity.

The space created by Wei Xiaobei is almost solidified, but it is still in a state of motion.

The flame in the mud ball constantly turns water into steam and slowly fills it in the air, while the water vapor in the air will condense on the surface of the mud ball due to the decrease of temperature, thus forming an extremely simple circulation system.

After knowing this, Wei Xiaobei thought in his mind for a while, and then selected the mud ball as the main key point to further expand the space.

"Up!"

With the gentle drink of Wei Xiaobei's mind, the ball of mud grew rapidly.

With the continuous growth of the mud ball, in reality, the gray boundary stone suspended in Wei Xiaobei's hands began to shrink slowly.

When the gray boundary stone was reduced to half of the previous one, Wei Xiaobei stopped the growth of the mud ball.

At this time, the diameter of the mud ball has been increased to 50 meters!

Undoubtedly, compared with the time when the space was created, the simple growth of the mud ball has a much smaller consumption of the grey boundary stone.

By this time, the thickness of the air layer on the surface of the mud ball had been thinned to less than five meters.

After looking at the current situation of the mud ball, Wei Xiaobei couldn't help frowning. It seems that something is wrong.

After thinking for a long time, Wei Xiaobei raised his eyebrows.

i see.

I forgot.

If the space exists in a circle, the utilization rate will undoubtedly be weakened a lot.

"Stretch!"

Then Wei Xiaobei began to trim the mud ball and stretch it like plasticine.

Under the control of Wei Xiaobei's mind, the mud ball quickly became flat, the edge extended outward, and soon formed a mud skin.

Wei Xiaobei really pulled a little hard. After stretching the mud skin, its vertical and horizontal dimensions were more than 300 meters, while its thickness was reduced to less than one meter!

To be precise, the thickness of the mud skin covering an area of 135 Mu is only about 72 cm.

Well, even Wei Xiaobei feels the instability of space at this time.

Mud skin is the foundation of this space. Too thin undoubtedly reduces the stability of the space.

To this end, Wei Xiaobei had to consume all the last half of the gray boundary stones, increasing the thickness of the mud skin.

However, this also brought unexpected joy to Wei Xiaobei.

According to the previous consumption ratio, the remaining half of the grey boundary stone can only double the thickness of the mud skin at most.

However, after all the grey boundary stones were exhausted, the thickness of the mud skin was surprisingly increased to five meters!

After discovering this, Wei Xiaobei couldn't help but be a little stunned and began to study the problem.

After consuming several hours of brain power, Wei Xiaobei confirmed that the shape of space has a different impact on the increased volume after the consumption of gray boundary stone.

In short, this influence is weakest in the form of sphere and strongest in the form of thin skin.

Of course, the sphere shape also has its own advantages, that is, the stability of space is the highest!

As for the thin skin form, its spatial stability is the weakest. Even if Wei Xiaobei ignores it, this space has its own tendency to collapse.

However, even so, the benefits of this thin skin form were written down by Wei Xiaobei.

In fact, in the process of developing from thin skin thickening to cuboid, this space should extract some additional things from the outside, so that the thickening degree of thin skin exceeds the expectation.

Of course, Wei Xiaobei can't solve this problem in such a little time if he wants to study it thoroughly.

When the mud skin thickness increased to five meters, the stability of the space improved a little, but it still belongs to the mud skin state, so there are still some black micro cracks at the edge of the space.

This makes Wei Xiaobei look a little black.

Those black tiny cracks will not be a good thing, that is, space cracks. Once this thing appears in any space, it is not a good thing.

Fortunately, those spatial cracks did not continue to increase after they appeared, which also showed the benefits of mud skin thickening.

Obviously, if you want to make the space more stable and let the space repair those cracks by itself, you need more gray boundary stones.

Thinking of this, Wei Xiaobei withdrew his mind from the space, and then took out the gray boundary stone formed by the collapse and condensation of Cuihu from the storage ring.

Broken grey boundary stone!

As can be seen from the name, the quality of this gray boundary stone formed by the collapse and condensation of Cuihu is much better than that of the previous gray boundary stone. (to be continued.)
