Two worlds, one yin and one yang, rotate each other, one is an iceberg beauty swaying in a dark red dress, and the other is a young dancer with a light blue coat. The gravitational fluctuations generated by both sides have caused a ring-shaped asteroid belt to appear in space.

Often, matter enters the universe from the sea of ​​chaos. After colliding with asteroids, a flare is formed, like a cosmic ribbon with rays.

It can be predicted that the dance of the two worlds of Yin and Yang will continue for a long time until the world is destroyed.

Moreover, Lu Yuan vaguely realized that the Qiankun world was producing an energy that was more advanced than "luck" - the Xuanhuang aura!

Just a little bit of mysterious yellow aura can give birth to an innate myth!

As for whether the Xuanhuang aura has a more powerful purpose, Lu Yuan is not sure.

"If I can obtain a large amount of Xuanhuang Qi in the future, how powerful will my greedy demon god be?!"

Lu Yuan's heart began to move, but it was a pity that he could not use Xuanhuang Qi now - because he was already a myth.

What's more, the production speed of Xuanhuang Aura is so slow that it takes about one million years to produce a unit, which is speechless.

As for the method to increase productivity, there is only one way: to advance the evolution of the world.

"The Xuanhuang Qi that a world can produce is obviously limited, otherwise the Pangu Continent should be full of innate myths."

"Each evolution stage can only produce a small amount of Xuanhuang Qi, and after that, more will never be born...so I have to plan carefully."

He couldn't wait to add all the bloodlines of the little mirage dragon, the ancient insect, the immortal giant turtle, and the crystal giant turtle!

The emergence of bloodlines is obviously a process of world evolution.

"There are too many turtle bloodlines now. I must find another powerful bloodline to neutralize it, otherwise it would be better if the world is full of turtles..."

Thinking of this, Lu Yuan invited him: "Friends, my world is deserted and I don't have the ability to transform."

"Please follow me in and give me some advice."

It was the same as before. A group of guests entered the "earth escape shuttle", and Lu Yuan used the ability of "different space" to cover the shuttle and teleported it to the Qiankun World.

Looking down from space, you will find that the area of ​​the Yang world has increased by more than a hundred times larger than the beginning.

Blue lakes and raised mountains appeared on the surface of the planet.

Lu Yuan’s gains in Wujie were so great that he could not calculate it himself.

All these gains have become part of the universe.

Those mountains are astonishingly huge, with a height of fifty kilometers and a length of hundreds of kilometers. They are simply a plateau.

The shorter ones are also 10 kilometers high.

If you observe carefully, you can also see the carvings of tortoise shells on these mountains.

The Yin world has expanded by about 20 times, frozen for thousands of miles, and life has disappeared - the environment of the Yin world has become even worse, and a dark brown haze appears on the surface of the planet, which is particularly harmful to the soul.

By chance, you can see red lights emitted from the Yin world, and the stripped gas drew spiral marks in space. The breath that destroyed everything was a little similar to the boundless chaotic wind.

Only Lu Yuan, the master of the Qiankun World, can travel unimpededly in the Yin World.

"No, you have invested heavily in Yang World, why does the Yin World grow so fast?" The crystal man of the crystal concrete civilization couldn't help but wonder, "According to the original calculation, shouldn't the growth rate of Yang World be much higher than that of Yin World?"

Lu Yuan was helpless and spread his hands: "I also found that the calculation situation did not match the actual situation. The main reason is that the Yin world absorbs more meteorites than the Yang world."

"Maybe it is because the Yang world instinctively rejects some disasters."

He pointed to a giant meteorite flying at high speed in the sky.

It flew in from the Sea of ​​Chaos, with a moving speed of Mach 12, a diameter of 120 kilometers, and an amazing size.

You should know that the asteroid extinct dinosaurs is only 12 kilometers in diameter. Once this meteorite hits the Yang world, the evolution of the Qiankun world will end most of the time!

But Lu Yuan was not worried at all, because this world had its own instincts.

Sure enough, the giant meteorite circled around and smashed into the Yin world with great momentum!

This was as good as hundreds of millions of Tsar nuclear bombs. A large amount of dust splashed up, polluting the entire sky, shaking the earth and magma reappeared.

"This kind of thing happens almost every day. The Qiankun World was born in a good place with abundant material resources."

Lu Yuan spread his hands: "The current Yang world is indeed bigger than the Yin world, but with the material supplement of meteorites, the growth rate of Yin world is indeed far higher than that of Yang world..."

However, the rest of the people looked serious. This information may have been found in the ninth era.

"So...so that's it..." Guiguzi murmured to himself.

Lu Yuan's crazy investment in the Yang world makes the Yang world bigger than the Yin world.

Once investment is stopped, it will be slowly overtaken.

What if it was the original Pangu Continent? No one would invest at all, and the gap between the two sides would grow wider and wider... In the end, it evolved into what it is now.

Everyone could only sigh. The existence of life added a bright color to the world, but it was also a kind of constraint. The so-called "the way of heaven can reduce the excess to make up for the shortcomings" may be like this.

"You should be able to move the material from the Yin world continuously to the Yang world, right?"

"It is feasible in theory, but it will cost extremely huge energy." Lu Yuan had no choice but to spread his hands, "I have considered this issue. If materialistic energy is used, at least one interstellar civilization is needed. With the help of an interstellar spacecraft, it will relocate materials for a long time, at least level 4 civilization or above."

"The environment in the Yin world is harsh, and even machines of interstellar civilizations are often damaged... This project volume is quite large."

"And as the two worlds continue to grow, the gravity will also become larger, and it is quite troublesome to maintain balance."

"If you use idealistic energy, it will consume a lot of spiritual rhyme... You may consume millions or tens of millions of spiritual rhymes at one time. I have not calculated it carefully."

The size of the Yin and Yang world is gradually increasing, which is also considered to be the planetary level. In addition, the material of the Yin world is not suitable for the longevity of life, and it requires Lu Yuan, the master, to purify it himself, so this expense is indeed quite large.

The Yin world is necessary, and it is an important part of the idealistic rules.

The production of the Xuanhuang aura requires the existence of the Yin world.

If Lu Yuan forcibly destroys the Yin world, the Yang world will also lose balance and then slowly wither.

The harmony of yin and yang is the truth of world development.

During this discussion, "Tiuluo·Flying Shuttle" slowly descended to the highest peak of the Yang world.

The clone of the tree of life here has grown to a height of 100 meters, and the emerald green leaves are like pieces of imperial green jade full of vitality.

As the first creature in the Qiankun world, the Tree of Life has considerable privileges: it can automatically regulate the surrounding climate environment, regulate the continental plate, control the landing of asteroids, etc.

In other words, this tree has part of the function of the will of the world.

Near the Tree of Life, the greenery is colorful, and green plants grow quietly.

These plants all grow from "Xiyuan", with more than a thousand plants in total.

However, the largest tree at present is only one meter high, just a small sapling.

"Why did you grow so much after not seeing each other for three years?" The strange people in the Snake Man Palace began to investigate one by one.

One of the crystal people, with the ability of "plant affinity", said dissatisfiedly: "Lu Yuan, you have to cultivate them well. They are the first batch of creatures in this world and can bring you huge wealth."

"There is no way, I don't know how to cultivate it..." Lu Yuan shrank his neck, and the growth of innate plants was positively correlated with the evolution of the world.

Even if he pours all his wealth into it, he will at most promote the evolution of the world.

"This is...Shatang Tree, come and see, do you think it looks like it?" The old snake man roared in fuss.

Everyone hurried over to watch, and saw that the sapling was extremely strange. Its trunk was like a crabapple and its whole body was white. It was as if soaked in frost and snow. Red lines faintly emerged from the twisted branches, like blood flowing.

"What's the use of this tree?" Lu Yuan asked.

"It is said that eating the fruits of this immortal tree can prevent people who cannot swim from drowning." An alien explained.

"Just...this is it?!" Lu Yuan was shocked. What kind of shit function?

"You are wrong, this is part of the idealistic rules. These rules make up the whole world."

"This is an immortal tree! Absolutely!" Another exclaimed.

The Immortal Tree is also known as the Dragon Blood Tree. It is said that after eating the fruits of the Immortal Tree, you can live forever.

"Eternal life is naturally impossible, at most it can only last for a long time. And in the first era, there was an ancient race called the Dragon Clan, which became strong because of its immortal trees." Guiguzi knew many ancient secrets and stood near these two centimeter-high saplings and told the story.

"The Dragon Clan, where are their people?"

"I don't know, maybe I'll run away or hide in a small world... Maybe I'm surviving? Don't underestimate the former big clan. They have innate spiritual plants or innate spiritual treasures and are very capable of survival."

Guiguzi sighed: "My civilization is not the first race to deal with the great disaster of the era. Some strong races are one step ahead of us, closed the floating mountain, and disappeared in this world. They even have magic weapons to regulate time and can endure it for a long time."

"But did not affect the entire Pangu continent when the Era disaster affected? The small world could not be spared, right?" Lu Yuan remembered the [Monster·Lingyan Ball] who was killed by himself. The one who controlled the [Monster·Lingyan Ball] wanted to escape the disaster through the ability of the different space, but they were still destroyed.

"When you know the truth about the Era disaster, it's too late to hide. But if you don't know, just hide?" Guiguzi asked back, "There are some powerful races in the world that have the ability to sense."

Lu Yuan's heart beat hard, and the most important thing is to "know and discover". If you don't know the truth of the Yin world, you will hide directly. There is indeed a chance to escape the great disaster.

In addition, the first era is indeed rich, with many treasures in heaven and earth. It is normal for some low-probability events to occur, such as divination and fortune-telling skills.

“Is there many races in this category?”

"Not many, but there are some. My civilization records a sentence about the tower top civilization in the literature."

"What?"

"Despicable is the passport of the mean, and noble is the epitaph of the noble - they should not refer to the fallen, the deadly enemy, and there is no despicable statement."

"But those races that escaped, who were invisible and watched the world perish again and again, no one knew where they were hiding. The civilization on the top of the tower discovered them, but they were kind-hearted and did not interfere with their choice."

"Hehe." Lu Yuan sneered, "The times are different, the ninth era is the last era."
