Chapter 610: The Cave Gate Opens

"Boom—" The entire Thunder World suddenly shook violently, shaking without any warning!

"Look, what is that thing?"

Luo Feng and his group were resting in the cave, and this recovery had lasted for several days. Suddenly, on this day, Cang Niu couldn't help but shout from outside the cave.

Immediately, the others in the cave walked out one after another.

A pitch-black hole that looked as if it had been torn open appeared; half of this black hole was on the mountain range, and half was inside the mountain range, with the surrounding space torn open, looking extremely eerie.

This terrifying scene shocked Luo Feng and his group. Of course, it wasn't just Luo Feng and the others; all the thousands of teams around the Wind-Thunder Canyon were so horrified by this scene that they were speechless.

"Babata, what is the situation?"

Facing a scene like the collapse of heaven, Luo Feng and the others were horrified, their voices even trembling slightly.

"It should be... an entrance to a world! Yes, a world entrance!" Babata's surprised voice rang out.

"A world entrance?"

Luo Feng and his group were all a bit confused and puzzled.

"It's a world-within-a-world," Babata said quickly.

"A world-within-a-world?"

Luo Feng and the others had only been in contact with the universe for a short time, after all, and didn't understand many things. "What is a world-within-a-world?"

"A World Lord can create a world, you know that! And within this world, they can build another world to hide inside. This 'world' within a world is called a 'world-within-a-world'."

At this moment, Su Fan stepped forward to explain. "However, to build a world within a world, first, the 'world-within-a-world' needs to be stable enough, which requires a large amount of Universe Crystals as a foundation."

"Universe Crystals!"

Now, Luo Feng and the others understood.

"The cost of building a world-within-a-world is very high. So, it is generally only done to hide treasures, sparing no cost to build a world-within-a-world," Babata said.

"Treasure?"

Upon hearing this, everyone's hearts stirred; this was an opportunity.

"That's right, it's treasure. This Thunder World was created by a World Lord named Kabu. It is said that this World Lord was quite wealthy, comparable to some poor Immortal-level powerhouses."

"However, when Kabu was besieged back then and died, no decent wealth was found. Many people are spreading rumors that Kabu must have had a place to hide his treasures."

Su Fan introduced again.

"Really?"

Upon hearing this, Lei Shen and the others' eyes lit up. One could imagine how precious the treasure left behind by a World Lord would be. If they could get their hands on some, they would be rich.

"No matter how much treasure there is, we need to have the strength to get it."

"If that world-within-a-world really was left behind by that World Lord Kabu, do you think his treasure is something we can covet?"

"There will inevitably be many powerhouses coming over."

Hong was still relatively calm. Once his words were spoken, Lei Shen and the others immediately sobered up. With just the strength of the few of them, planning to scheme for a World Lord's treasure was really no different from seeking death.

"Haha! Hong is right."

"However, although the treasure might be out of reach, everyone, don't forget that there are a large number of Universe Crystals in this world-within-a-world. We can mine the Universe Crystals."

Su Fan said with a smile.

He naturally knew what would happen next, because due to the Universe Mercenary Alliance, people above the Star level could not enter.

Therefore, the world-within-a-world would be the domain of the Star-level in the future.

Of course, it was actually the work of those top forces in Black Dragon Mountain; other lone individuals or small forces simply couldn't make it work.

In the original work, Luo Feng relied on being the protagonist, plus having the surveying machine that Babata got from the Yunmo Planet spaceship, to occupy the lion's share.

That Yunmo Planet spaceship was built by an Immortal-level powerhouse, so it naturally surpassed everyone else.

Not only did it discover a large number of Universe Crystals, but it also discovered Thunder Stones; that item was the most important thing.

The wealth Luo Feng obtained later—although there were many Universe Crystals, the gap compared to the treasures inside that castle was too great.

Of course, Thunder Stones themselves had no value, but under that intelligent life form, they could be exchanged for treasures in the castle, which was a different story.

In the original work, Luo Feng and the others exchanged for forty or fifty treasures, and after selling them, they had a total of over ten trillion Universe coins.

This could be considered a significant amount of wealth even for a World Lord.

So this time, Su Fan prepared to remind Luo Feng and the others to mine more Thunder Stones in advance, so they could exchange for more treasures later.

Of course, this was also extremely difficult. First of all, he didn't know what exactly Thunder Stones were.

He only knew they contained a trace of thunder power, so it was still somewhat difficult to find them.

Of course, difficulty is difficulty, but once they mined them in advance, they would have a great advantage.

Moreover, Su Fan's goal was to first exchange for that D-grade railgun. With this item, they would have sufficient deterrence, and then they could strive for greater benefits.

Of course, Su Fan also knew that Babata's choice in the original work was better: choosing to exchange for the Life Fruit to let their Demon Cloud Vine evolve.

But if they could mine them in advance this time, then the D-grade railgun could also be exchanged.

This item was a great weapon of mass destruction; it could be used not only here but also in the future. A D-grade railgun could even threaten Domain Lords.

For Earth, it was absolutely beneficial.

Of course, if exchanged for money, it could be exchanged for even more.

So this time, no matter what, he had to earn as much wealth as possible, because it would be very difficult for him to obtain such wealth in the future.

He was not Luo Feng. Even in the future Universe Peak Genius Battle, with his ability, even Lei Shen might not be comparable to him; at most, he would perform well in Black Dragon Mountain.

But wanting to be like Luo Feng was simply impossible.

So he could not be like Luo Feng, joining the Virtual Universe Company and becoming a core disciple, where training resources were available as needed.

As such, he had to earn money slowly.

During this time, he was on Qiu Long Star and was very clear about the difficulty of earning money.

In one year, he had only earned a few hundred million Black Dragon coins. Of course, if he sold some secret techniques, he could also exchange them for some wealth.

For example, that Soul-Piercing Needle could probably be worth hundreds of billions of Ganwu coins.

Of course, this was also an estimate; it might be higher, and of course, it might be lower.

But for him to buy a planet, it was still somewhat difficult, so for this world-within-a-world, he had to earn a large amount of wealth.

Only then would life be better in the future.

Whoosh, whoosh, whoosh!

In the Thunder World's Wind-Thunder Canyon, countless Star-level warriors were now pouring in crazily.

And outside, it went without saying; countless spaceships were surging crazily toward the planet where the Thunder World was located.

"Millions of Star-level beings."

Su Fan was very clear that before long, this world-within-a-world would be flooded with one or two million Star-level cultivators, which was extremely terrifying.

And they would need to compete with these one or two million people. ===== CHAPTER 611 =====
