"Rumbling~~~~" The strange vibration and suction force are constantly transmitted through the oscillation and distortion of spatial energy.

Now, it's been a full 5 years since the departure from the star path.

For the past 5 years, Shen Chong and Xiao Yi have been carefully exploring in the 'Outer Dark Realm', in order to find a reference object that only has the right path to find.

But so far, it is just like a fly that can't find the north.

In the past 5 years, they have been extremely careful, and when they encounter areas with spatial energy anomalies, Xiao Yi can find them in advance, and the two would rather take a detour than take risks. Such caution did not expose them to any danger.

On this day, the two continued to accompany each other in the 'Outer Dark Realm' and kept searching, and suddenly, Shen Chong's divine sense discovered something in front of them.

This discovery lifted Shen Chong's spirits.

"Xiao Yi, there is a discovery !!"

During the divine sense investigation, a planet in front of it, its whole body was black and gray, and while rotating rapidly, it was gliding rapidly in the dark starry sky of the 'Outer Dark Realm'. This glide is actually a circular revolution around the black hole in the center of the entire 'Boundless Dark Realm'.

The black hole has a wide range of influence and strong suction power, and even a hard planet that rotates so quickly can it be captured, so that it does not have enough centrifugal force to escape.

The gliding speed of this black star was very fast, and it appeared in front of Shen Chong's eyes, almost like a meteor.

In the star map of the Holy Venerable, at the edge of the correct path, there is a star orbit crossed by this planet.

In other words, as long as Shen Chong and Xiao Yi catch up with this planet, and wait on the planet for the star orbit to cross the correct star path, and then return to the star path, they will find the correct path.

"Catch up!!" Immediately, Shen Chong and Xiao Yi quickly chased after the black planet.

The speed at which the planet revolves around the black hole is extremely fast, and Shen Chong and Xiao Yi almost used all their strength to catch up with the planet along the star orbit and more than ten days later.

And on the planet that rotated like a top, it stopped.

Stopping on the planet, the bodies of the two began to rotate rapidly with the planet, and Shen Chong's divine consciousness and realm completely enveloped the entire black planet.

Shen Chong's realm was formed by the 'Qiankun Origin Qi' as energy, so the permeability was much stronger than that of ordinary cultivators, who were composed of divine spiritual power.

He was also bored, so he used the domain to explore beneath the hard surface of the black planet, just to see if the interior of the planet was getting denser and denser, or if there were strange veins.

Before investigating, Shen Chong didn't have much expectations.

But after some painstaking investigation, he made a surprising discovery.

After the field penetrated nearly a thousand meters into the rock layer of the black planet, he actually found some huge hollow drums thousands of kilometers below the crust of the black planet.

What's even more peculiar is that the interior space formed by the hollow drum is densely covered with dark plants.

He really didn't expect that in such a harsh environment as the 'Outer Dark Realm', he could find traces of creatures.

In the Star Chart of the Holy Venerable, there is no mention of the existence of creatures in the 'Boundless Darkness'.

Perhaps the focus of his original exploration was not within the scope of this 'Outer Dark Realm', so he only swept away his divine sense, and did not conduct a deeper investigation in the domain, so he ignored the existence of these strange plants.

Anyway, whatever the reason, they now have something new to discover, which is exciting enough.

Immediately, Shen Chong and Xiao Yi, unable to suppress their curiosity, found the right position on the surface of the black planet, and made great efforts to dig a shaft and began to investigate deeply.

The hardness of this black planet is comparable to that of a low-grade artifact, and it is not easy to dig a shaft that can allow them to enter. Shen Chong and Xiao Yi took turns to fight, and after one ran out of energy, the other took over.

The two kept digging down, and it took more than half a year to dig to the hollow drum position thousands of meters underground.

Standing in front of them, Shen Chong and Xiao Yi really felt the strangeness of these plants.

In front of me, in the hollow drum area thousands of meters wide, it seems to be a black wasteland, overgrown with pitch-black plants.

There are two types of plants, one resembles a dead tree, which can also be said to resemble coral. The other is like ordinary grass.

Both plants are dark throughout, and in terms of hardness, they also go to two extremes.

The hardness of the tree-like plant is comparable to that of a high-grade artifact, and the root system is deeply rooted in the soil. The hardness of the grass plant may not be high, but the toughness is very large, Shen Chong tried to pull hard, but he didn't break it for a while.

The entire hollow drum space was filled with a faint dark attribute aura and an extremely thin aura of 'Qiankun Origin Qi'.

It seems that these plants can rely on this black planet to produce extremely thin dark attribute aura.

It's just that such a thin dark attribute aura is useless to Shen Chong.

But he still decided to harvest some of the two strange plants and send them back for research. The reason why it is not dug up by the roots is because even if the whole plant is dug up, it is impossible to store living creatures in the spatial ring, not even plants.

After harvesting the black plants, Shen Chong continued to explore the interior of the black planet with the domain.

He wanted to find out what it was that made plants grow on this black planet.

The density of the planet was so high that even Shen Chong's realm infiltrated was extremely difficult. However, Shen Chong still tried to control the extension of the domain to the interior of the planet.

In the interior of such a dense planet, it is impossible to find out what is going on inside with divine sense. To know the situation inside the planet, you can only find out by the domain.

The field continues to extend to the center of the earth. 10 meters, 100 meters, 500 meters, 1,000 meters.

After extending a full 1,500 meters, Shen Chong was suddenly stunned.

Because in the extension of his realm, he felt the core of the black planet. It was just a ball ten meters in diameter, but it was so hard and dense that it could even hinder his realm.

Shen Chong estimated that the hardness of this core could already be compared with the best artifact.

Shen Chong's realm spread, enveloping the entire pronucleus and examining it carefully. But I found that the core was round and unified, except for the hard and high temperature, there was nothing special.

Perhaps, it is this 'black planet' that has reached such hardness for many years under the terrifying high pressure of the outer dark world.

After some investigation, there was no special discovery, Shen Chong was about to reclaim the domain, but suddenly found that a mass of matter in the kernel escaped quickly, and then fled back into the kernel.

"Is it a creature or something!!? is it possible that on this planet, there are not only half of the hollow ground with plants underground, but also in the core of the planet, there are also living creatures???

Shen Chong's whole person was stunned.

He couldn't be mistaken. If you look with your eyes, you may be dazzled, but under the wrapping of the field, it is absolutely impossible to have an illusion.

Just now, there was indeed a mass of substance with a strong aura, which came out of the core and hid back again.

The realm cannot be infiltrated, but you can use a harder holy treasure to dig into the core of the earth to investigate.

"Gotta find out what's inside!!" curiosity struck.

At that moment, Shen Chong summoned the Twin Beasts Liuying, and with a movement of his mind, he activated the 'Qiankun Origin Qi', condensing the spiritual energy on the surface of the Holy Treasure Changgong, and stabbed it to the ground.

With this stab, Shen Chong used all his remaining energy, but he only pierced ten meters into the ground.

Shen Chong couldn't help but be speechless. That blow just now was enough to destroy an ordinary planet, or kill a powerhouse in the late stage of the God King. And in the bottom of this 'outer dark world' planet, it can only pierce 10 meters.

The hardness of this planet is unimaginable.

It is said that the strong have the ability to penetrate the heavens and the earth. At this moment, Shen Chong realized that nature was the most terrifying and unpredictable existence.

I wanted to keep digging, or simply use the domain to find out what is at the core of this planet.

But recently, Shen Chong and the others have been in a hurry, digging thousands of kilometers above the black planet, before they came to the hollow drum area where they are now, and their own energy consumption is also very strong.

Everything, we can only wait for some recovery, and then do the investigation and try.

Immediately, the two sat cross-legged and began to quietly regain their energy.

In this area of the 'Outer Dark Realm', the concentration of heaven and earth aura is high enough, and even a little too high.

Therefore, every time they absorbed and refined the external aura to restore their own energy, it would take Shen Chong and Xiao Yi a long time.

It's like a regular biscuit, because it's soft, and it's easy for a person to eat and absorb the energy of the biscuit.

However, if you replace ordinary biscuits with super compressed biscuits, then whether you break them and eat them, or absorb them after eating, it will be much more laborious and time-consuming.

In the underground of the black planet without any interference, this restoration took Shen Chong and them more than ten days.

That's a lot faster than the planet's outside.

Moreover, Shen Chong's recovery speed, if other God Emperor masters heard it, it was estimated that he would vomit blood in a depressed manner. Other God Emperors didn't have the skills and specialties to quickly recover energy like Shen Chong. In the 'Outer Dark Realm', once their spiritual power is consumed by one-third, they will immediately find a place to recover, after all, a perfect state is the guarantee that they can escape when they encounter danger.

And the recovery of this 1/3 of the aura takes a month as fast as it is, and even more than half a year if it is slow.

Therefore, those God Emperor powerhouses would prepare a large number of high-grade Shen Yun stones before entering the 'Outer Dark Realm' to explore. Once your own energy is depleted, you can directly absorb the energy in Shen Yun Stone to replenish it to save time.

It's not that Shen Chong can't afford to consume Shen Yun Stone. He just didn't have to rush, there was no need to rush.

Now, the energy was finally restored, and Shen Chong immediately took out the Twin Beast Flow Fireflies again, stabbing out again along the original small hole, and each time he went down ten meters deeper.

After Shen Chong stabbed dozens of times, the energy in his body was exhausted again.

This time, it was replaced by Xiao Yi to take over the downward digging.

After the two of them ran out of energy, they rested and recovered again.

It was as if the people who were digging for treasure in the earth had persevered for more than two months to penetrate that small hole into the core of the black planet.

Finally, Shen Chong's realm could directly touch the earth's core without any barrier.

He and Xiao Yi were shocked.

The time has come to figure out the nuclear secrets.

At this moment, Shen Chong even had a hunch, as if this secret was very close to his goal of entering the 'Boundless Dark Realm' this time.
