Liu Yu looked at the inch-sized rhombus-shaped crystal in his hand and fell into deep thought.
Should he let the Heart of the Heavenly Dao devour it?
In Liu Yu's hand was the item left behind by the Sword Heart World's Heavenly Dao after its death. It was called the Heart of the Heavenly Dao.
The Heart of the Heavenly Dao was the combination of a world's laws and origin. It contained the laws of the entire world.
If a cultivator obtained the Heart of the Heavenly Dao and comprehended it, their cultivation level would be no different from cheating.
Liu Yu thought about it and decided to forget about it. The Heart of the Heavenly Dao was a treasure. It would be a waste to let the small world devour it.
In the blink of an eye, 10,000 years had passed. The small world had completely devoured the entire Sword Heart World. From then on, the Sword Heart World disappeared into the vast void.
After the small world devoured the Sword Heart World, it expanded to ten light years in size.
At the same time, the small world also increased by thousands of planes.
The small world now had a continent and thousands of planes. It could be considered a relatively prosperous world.
The current plane was not the same as the one during the Age of the Gods. The current plane had the Starry Sky Plane and the Continent Plane. These planes were not small. The smallest Starry Sky Plane was about a million light years in size, while the largest Starry Sky Plane was about a billion light years in size.
However, the laws of these planes were more incomplete and the worlds' spaces were weaker.
With the current Four Great Empires of the Primordial World, they could casually send a Martial God to destroy a plane.
In addition, in order to protect these planes, Liu Yu had also set some rules. Immortal God level cultivators were not allowed to enter the planes. Even if they forcefully entered, their cultivation level would be restricted by the Heavenly Dao Liu Yu. Their strength would be suppressed to the point that they could only destroy the continents on the planets.
This kind of suppression was quite ruthless.
As for the Four Great Empires of the Primordial World, they had also gained a lot of benefits by invading the Sword Heart World.
They had different cultivation techniques, divine weapons, precious medicines, high-level spirit stones and other items for cultivation.
It was very difficult to calculate how much wealth a world had. In any case, the Four Great Empires had made a huge profit from this invasion.
Of course, the Rogue Cultivator Alliance of the Primordial World had also made a fortune.
Now, the Rogue Cultivator Alliance had been integrated by experts. Their strength was slightly weaker than the Four Great Empires.
From then on, the five great powers of the Primordial World kept each other in check.
Most importantly, after the small world's foundation strengthened, Liu Yu's realm also reached peak Five Element Realm.
The Five Elements Realm might not be omniscient and omnipotent, but traveling a million light years in the blink of an eye was a piece of cake for them.
What was even more amazing was the ability to travel between planes. For example, the various planes in the small world could be freely traveled between planes when one's strength reached the Five Elements Realm. However, with the rules set by Liu Yu, these people didn't dare to travel between planes.
If they were in the real world, it would be easy for such an expert to destroy a galaxy that was tens of thousands of light years away with a wave of his hand.
The space in the real world was still very sturdy. It wasn't as weak as people thought.
After Liu Yu dealt with the Otherworld Invasion, Liu Yu also returned to the real world.
Right now, Liu Yu was in the space-time of five million years ago in the real world.
As for the real world's Origin Core Space, Liu Yu had no clue at all.
The real world was very huge. Liu Yu was only hoping to find some clues on Earth, but in the end, there were no clues.
After thinking for a long time, Liu Yu could only move the millions of drops of the world's Origin Core and flow down the River of Time and Space, returning to the original space-time of the real world.
