Now that Zhao Song wants to build a blood sea in the natal world, the easiest way is to directly collect some blood-colored liquid from the desolate blood sea......

But there is also a problem with it, that is, the blood-colored liquid in the sea of desolate blood is too corrosive and infectious, and his natal world is only at the level of a small thousand, which is a little unbearable......

So the first thing to be solved now is the problem that Xiao Qianjie can't bear the blood-colored liquid......

However, in the past, Zhao Song did not have a good solution to this problem, but since Zhao Song got five lotus seeds from the Twelve Rank Industry Fire Red Lotus, Zhao Song already had a proper solution to this thorny problem in his heart.

Zhao Song planned to use the origin of the blood lotus seed to imitate the principle of Pangu's navel to build a simplified version of the blood sea, but it was to refine an innate lotus seed......

"The white lotus seed in the pure world should be kept, there is only one in the world now, and it can't be wasted like this, so you can only use one blood lotus seed."

As soon as he thought of it, Zhao Song took out a blood lotus seed and directly urged the true fire to refine it......

This blood lotus seed can be said to be the third generation of the Chaos Blue Lotus, although it is still innate, but with Zhao Song's powerful mana, it was quickly refined and turned into a red liquid.

Looking at the active red liquid in his hand, Zhao Song was very satisfied, if he had refined the blood lotus seed before he comprehended the law of creation, then now this liquid would be inactive, unlike now, it seemed to have a vitality.

This vitality is very important, which means that it will continue to grow and grow, which is very in line with Zhao Song's needs, otherwise a dead thing has no potential.

Looking at this vibrant red liquid, Zhao Song carefully admired and observed it, and then was satisfied to include it in the natal world.

After this red liquid entered the natal world, Zhao Song controlled it to flow to the bottom of the fetal membranes of the small thousand worlds, and the liquid gradually and evenly dispersed in the lower half of the fetal membranes of the world.

Then he controlled the Zhou Tian Star Dou Great Array that had been formed before, and changed into a hemispherical shape, enveloping the upper part of the natal world.

After the upper and lower arrangements were completed, Zhao Song controlled the contact between the two in the middle of the fetal membranes of the world......

Because it is within Zhao Song's natal world, his control is very strong, so the two are smoothly connected together.

Zhao Song watched quietly, where there was a problem, he would control and deal with it, and then wait for them to be completely docked together......

In this way, a few days later, when the two were finally about to be completely connected, Zhao Song mentioned his spirit and concentrated on controlling it to avoid accidents......

After a while, the two had all covered the entire heaven and earth fetal membranes without dead ends.

At the moment when the blood-colored liquid and the Star Dou Great Array were completely docked, the natal world suddenly froze, and then suddenly expanded a few times......

"Finally fully promoted to the middle thousand worlds......"

Zhao Song looked at the natal world that had expanded a lot, and he couldn't help but feel a sense of pride in his heart.

At this moment, Zhao Song's body suddenly became relaxed, and his injuries were a little better.

After a closer look, he found that the upper part of the natal world emitted a burst of silver light, while the lower half emitted a stream of blood light, and the two lights flickered alternately......

"Turbidity alternates, yin and yang separate ......"

Zhao Song looked at this scene and suddenly realized.

Now that the natal world has been officially promoted to the middle thousand world, the yin and yang system has been completed, and the world's digestion and accommodation capacity has increased dramatically, some heavenly and earthly treasures such as the corpses of fierce beasts and the turbidity of the earth that Zhao Song had received before were finally completely digested at the moment when they were promoted in the world......

When the natal world regained its balance, the pressure of the original world on the physical body was all involuted, and it was blessed on the fetal membranes of heaven and earth, which would not only slowly increase the strength of the fetal membranes, but also reduce the burden on the body, so now Zhao Song felt relaxed.

After carefully checking the natal world again, Zhao Song found that although the world had regained its balance now, there was still a little difference between heaven and earth.

"The liquid transformed by the blood lotus is still a bit weak, far less than the Zhou Tian Star Dou Great Array......"

I saw that there was already a prototype of the heavenly realm at the junction of the starry sky and the fetal membranes of heaven and earth, but there was no prototype of the underworld at the junction of the blood lotus liquid and the fetal membranes of heaven and earth.

"I don't know if the lower part of the fetal membrane of the natal world can resist the erosion of the blood-colored liquid in the sea of desolate blood?

Now only by absorbing some blood-colored liquid can I strengthen the power of the Yin side of the natal world......"

Thinking of this, Zhao Song collected a little bit of blood sea "sea water" to the bottom of the natal world......

After a while, I found that I don't know if it was because of the blood lotus seed or the reason for the promotion of the world, and there was no sign of erosion of the fetal membranes in the natal world.

"Great, now I can absorb some more......"

Zhao Song was pleasantly surprised and immediately urged the natal world to absorb the blood-colored liquid in the sea of blood with all his might.

The natal world is like a bottomless pit that continuously absorbs blood-colored liquid......

And so it goes......

There was finally a feeling of fullness from the natal world, and Zhao Song hurriedly stopped absorbing it, so as not to exceed the standard again......

"I think it's okay now......"

Zhao Song felt that after absorbing so much blood sea "sea water", how could the natal world be balanced by yin and yang.

"How so?"

Zhao Song looked at the natal world with great anticipation, and found that there was still a bit of a gap between heaven and earth, but he could no longer absorb the "sea water" of the blood sea, otherwise the natal world would not be able to bear it.

After searching carefully, Zhao Song finally found the reason......

It's not that the blood sea formed in the natal world is weak, it's that the Zhou Tian Star Dou Great Array is too strong......

The Zhou Tian Star Dou Great Array in the natal world was copied by Zhao Song exactly like the large array in the Flood Desolate Starry Sky, but there were not so many real stars and star power, but it would still operate on its own like the Great Array in the Flood Desolate Starry Sky, transforming all kinds of energy to supply the world.

And the sea of blood in the natal world was imitated by Zhao Song refining a blood lotus seed as a container, and then introducing the blood-colored liquid in the sea of blood in the desolate wilderness, but even so, it was far worse than the sea of blood turned into the navel of the Pangu Great God, and there was also a certain gap with the Zhou Tian Star Dou Great Array.

Although the blood lotus seed is still active after refining and can grow slowly, it takes too long, so the blood sea in the natal world can't operate on its own like the desolate blood sea now......

"The function of the blood sea in the natal world needs to be further strengthened, at least it must be able to operate on its own, but how can it be done......

Zhao Song wanted to refine another blood lotus seed at first, but now it was too late, the blood sea container transformed by the blood lotus seed had already been connected with the space formed by the Zhou Tian Star Dou Great Array, and fused with the fetal membrane of the natal world, and now it was not so easy to add something more.

"Now I can only try to plant a blood lotus seed in the natal world first, and see if I can strengthen the digestion ability of the blood sea to the extent that it can run on its own......"

To say that when the original law of creation was not known, this would give birth to an innate spiritual root, which would be extremely difficult......

However, now that Zhao Song has comprehended some of the laws of creation, as long as the mana is transformed into the power of creation through the laws of creation, then it is still easy to spawn......

Thinking of this, Zhao Song couldn't wait to take a blood lotus seed, and threw it into the sea of blood in the natal world with a reluctant face......
