Underground Palace, Shilan World Lord Appears

"Alright, let's take the spaceship then." Yang Yu flew in the sky for most of the day and, apart from a few Fierce Beast, did not find any humans, so he was not afraid of being discovered when he took out the spaceship.

Inside the Black Dragon Spaceship.

Yang Yu looked at the scene outside the panoramic simulation.

This World within a World is indeed quite different from the World within a World Thunder World in the Original Work; at least it is much 'quiet'.

Even the number of Fierce Beast has decreased significantly, making them a rare sight.

As Yang Yu and Babata continued their exploration and journey towards the central Core Region, they discovered quite a few Universe Crystal along the way.

However, the quantities were relatively small, and Yang Yu was too lazy to stop and collect them. He simply had Babata write down the locations, and once they reached the Core Region, he would release some robots to collect them.

The priority now is to get to the central area and see what secrets this World within a World holds.

One hour later.

Yang Yu stepped off the spaceship. Babata's Precision Detector showed that the reserves of Universe Crystal beneath this plain were astonishing; an ordinary Star Level could easily become wealthy with just a single dig!

But Yang Yu's focus wasn't on collecting Universe Crystal. "Babata, take out the robot and dig for Universe Crystal. Just dig slowly. Anyway, it's just us here for now, so we don't have to worry about others taking them. I'm going to explore this place properly now."

"Okay, there's no skill required to dig this thing, just be careful while you're exploring," Babata said.

"No problem." After saying that, Yang Yu used his powerful Mental Force to explore his surroundings.

In the outer World Lord World, Yang Yu's Mental Force could only cover less than 10,000 meters, but here he could easily cover a radius of 100,000 meters!

They can even go thousands of meters underground, which is already a very large search area.

However, this core plain is quite large, covering approximately tens of thousands of square kilometers. Searching the entire area would be no easy task.

Just as Yang Yu was focusing all his attention on searching his surroundings, Babata was controlling three robots to begin drilling and mining on the other side.

The reserves of Universe Crystal here are indeed quite good. Yang Yu glanced at them and saw that these ordinary spaceship Maintenance Robot, each with a shovel, dug up Universe Crystal in just a few minutes.

Then it's an assembly line operation: two robots dig, and Babata directs another robot to break down the excavated Universe Crystal into standard Universe Coin.

Generally speaking, one square Universe Crystal, that is, a Universe Crystal with a length, width, and height of one meter, can be decomposed into one thousand standard Universe Coin.

This kind of Universe Coin can be used by any country and any race in the Primal Universe!

In just a few minutes, Babata directed the robots to excavate dozens of cubic meters of Universe Crystal, which were worth tens of thousands of Universe Coin, tens of millions of Ganwu Dollar, and hundreds of billions of Black Dragon Dollar!

For an average Star Level Adventurer, acquiring just this much would be enough to live comfortably for the rest of their life.

After watching for a while, Yang Yu continued to focus his attention on exploration.

Gradually, Yang Yu began exploring the other side of the plain.

Half a day later.

Having reached the edge of the plains, Yang Yu finally noticed something amiss!

A hidden underground palace exists more than 800 meters underground!

"Finally, I've found you."

Yang Yu immediately called to Babata, "Stop mining for now, bring the robot over, there's a big discovery here."

"What a great discovery, Yang Yu! I'm really into digging, and I've already unearthed tens of thousands of cubic meters of Universe Crystal in such a short time." Babata was currently immersed in the joy of mining.

"What a discovery! There's an underground palace more than 800 meters below the surface. Quickly bring the robots over to take a look."

"An underground palace?" Babata was also taken aback. You should know that a typical World Lord can only create one world. If he wants to create another world within a world, the effort and resources required are astronomical.

The fact that such a vast World within a World was created likely indicates the existence of a great secret, something Babata was well aware of. However, even though the Shilan World within a World wasn't very large, thoroughly exploring it would still take a considerable amount of time.

Rather than wasting time on this vague 'secret' from the start, Babata would prefer to dig out the actual Universe Crystal.

After all, this stuff is everywhere underground; one shovelful and you'll get a whole bunch of Universe Coin!

But now that Yang Yu has discovered the secret from a distance, it's worth going over to take a look.

Babata, who was controlling the robot that had arrived, followed Yang Yu down into the underground. He then had the robot lead the way, with the two of them following behind.

In this completely unknown world, it's always good to be cautious.

One hundred meters, two hundred meters.

800 meters.

Finally, the two arrived at the Underground Palace.

"Yang Yu, my detectors haven't detected any obvious danger, but just to be on the safe side, let's have the robot lead the way."

"OK."

The two mining robots then stepped forward and opened the palace gates.

"Whoosh~"

The ten-meter-high gate slowly opened.

The once dark palace was instantly illuminated by bright light as the doors were opened, revealing the previously pitch-black underground beneath.

Neither robot was attacked at this time.

However, we cannot be careless.

Next, Babata remotely controlled the robot to explore the entire palace and confirmed that there was no danger.

Before entering, Yang Yu still had the Moyun Vine extend its tendrils inside to see if the object containing life energy would be attacked.

"Alright, cautious little guy, come in quickly. It's very safe here; I won't attack you."

A phantom light began to condense, and then an old man with a white beard appeared in front of the palace.

"Who are you?" Yang Yu asked.

"Now that you've entered this place, I am naturally its master. However, by the time you appear, I should have already perished over ten million years ago. This place is merely a memory left behind by me in my previous life."

The white-bearded old man sighed. "Alright, come in, lucky little fellow."

Sensing that the Moyun Vine had indeed not been attacked, and that the old man's appearance matched that of the Shilan World Lord tens of millions of years ago, Yang Yu boldly entered the palace.

The moment Yang Yu stepped into the palace, the doors slammed shut.

"Don't worry, only you can know what's going to happen next. If it leaks out, it will bring you utter destruction. My palace has the ability to shield you from most external instruments."

The old man with the light and shadow said with a smile from ahead.

Upon reaching the palace hall, the white-bearded old man gestured for Yang Yu to sit down.

"Little fellow, you were able to pass through the Time Storm I left outside, which clearly shows your talent. Moreover, you have extremely high potential in the fundamental Origin Law of time. Therefore, you are qualified to receive the treasure I left behind."

"A treasure?" Yang Yu was overjoyed upon hearing this. Sure enough, the World within a World that Shilan World Lord had painstakingly created was no ordinary place. He hadn't expected such a good thing to happen.

"What conditions must be met to obtain your treasure, senior?" Yang Yu asked.

"Hehe, little guy, you must have a lot of questions, but what I left behind are just simple memories. They can't answer your questions, but they don't need to. In short, the fact that you passed the screening means that you have gained my approval and are fully qualified to receive the treasures and inheritance I left behind."

The white-bearded old man was unusually kind and gentle, as if he understood Yang Yu's question.

"Ordinary weapons are one thing, but I would be heartbroken if my most prized possession, the 'Shilan Secret Technique,' were lost. Moreover, my expertise isn't limited to Light Law and time; in my later years, I also conducted in-depth research Light Law Leidian Leidian wind. I even attempted to gain inspiration from studying these three fundamental laws to break through to immortality, and perhaps even become a true powerhouse among immortals."

"However, my ambition was too great back then. My greatest strength was undoubtedly the Light Origin Law, but I arrogantly became distracted by Leidian and wind, trying to gain insight into the Time Law by studying these two laws, and then to master a shocking Secret Technique that I accidentally obtained on the Outer-Domain Battlefield."

"But clearly, my talent isn't enough." The white-bearded old man said this with a bitter and resentful expression.

"If I had focused on the Light Origin Law back then, I would have been very confident of achieving immortality!"

"But such immortality is merely the most ordinary and common kind of immortality, far from satisfying my ambition. Just then, I acquired the <Wind-Thunder-Time Secret Technique>, and naturally, my ambition began to grow."

"I abandoned the Light Origin Law, which was just one step away from perfection, and instead focused my attention on studying this Secret Technique. To this end, I even spent a great deal of money to create this World within a World so that I could concentrate on my research."

"Unfortunately, millions of years have passed, and although I have made considerable progress in the laws of Leidian, wind, and Time Law under the guidance of this Secret Technique, and have even gained the recognition of the Origin Law, I still haven't even qualified to learn this Secret Technique!"

The white-bearded old man looked regretful, while Yang Yu listened quietly.

After a long while, when the white-bearded old man had calmed down, he continued.

"I'm sorry to have made you laugh at me. It's just that millions of years of effort have all come to naught in a single day. The blow to me was too great. When I finally came to my senses and prepared to abandon this Secret Technique and first achieve immortality through the Light Origin Law, it was too late."

"At this time, my lifespan is only a little over 100,000 years. Originally, I was very confident that I could fully comprehend the Light Law and break through to immortality in this short time. Although I would lose the qualification to learn this Secret Technique, I would not need to worry about my lifespan. Moreover, I can train the younger generation and let them learn and master this Secret Technique."

"But then something unexpected happened. I had to go out for some reason, but my enemy found out. In that secret realm, I unleashed a power comparable to an ordinary immortal. Although I killed all the enemies who had been lying in ambush, my soul suffered irreversible damage. After trying everything to no avail, I finally resigned myself to my fate."

The white-bearded old man looked sorrowful as he spoke of this.

"Because I have been immersed in the study of Secret Technique for many years, I have not been able to have offspring. When my life comes to an end, I simply will not have enough time to raise a talented descendant."

"Instead of doing that, I simply left this Secret Technique, along with all the treasures I've collected over the years, in this World within a World. Then I set up a rigorous selection mechanism to filter out qualified successors over the long years. This way, all my efforts and hard work over the years won't have been in vain."

"My homeland is the Black Dragon Mountain Empire, and naturally I had to return before I died. In the final stage of my life, I chose to return to my birthplace, which is this planet. I knew there was a high probability that after my demise, my world would become the assessment world for the Universe Mercenary Alliance, so I set up an extremely strict selection mechanism outside. Although I don't know how many years have passed, I finally waited for you."

The white-bearded old man looked at Yang Yu with satisfaction. "To pass the selection of the Time Storm, young man, your talent, comprehension, and willpower are all top-notch. Although it's still uncertain whether you'll be qualified to learn the <Wind-Thunder-Time Secret Technique> in the future, you're still much more promising than I am."

"I hope you..." The white-bearded man suddenly revealed a sharp glint in his eyes, and a Ling Lie aura suddenly erupted from him.

"Even if you ultimately don't qualify to learn this Secret Technique, I still hope you can pass it down until someone is able to learn it! As long as you master this Secret Technique at the World Lord stage, you're guaranteed at least a peak-level Peak Marquis Immortal after becoming an Immortal!"

"A single breakthrough would easily make me King-level Immortal, and I could even glimpse the legendary Venerable realm!"

"Oh, by the way, perhaps you don't know about being granted a title of Marquis or King-level Immortal yet, but that's alright, you'll find out after you get the treasure I left you."

The white-bearded old man said, "Alright, having said so much, it's time to return completely. Among these treasures is an unknown opportunity that I risked my life to seize on the Outer-Domain Battlefield. It's a pity that I didn't see 'it' hatch in my lifetime. It would be a great regret if it remained buried in this World within a World. I just don't know if 'it' has been born after all these years."

The white-bearded old man looked forlorn. "Time, oh time, what has it left behind in the end?"

With a long sigh, the light and shadows vanished, and the entire palace fell silent.

"Yang Yu, it seems we've really discovered an incredible treasure." Babata, who hadn't spoken until now, finally spoke up.

"Secret Technique that leads directly to the Peak Marquis once you master it! If my master had obtained it back then, even if it wasn't suitable for his own cultivation, he could have sold it for an unimaginable fortune! With that wealth, he wouldn't have perished."

Babata sounded a little disappointed at the end.

"But it's alright. It's a good thing that you, Yang Yu, have obtained such a heaven-defying Secret Technique. Moreover, this old man said he left behind many treasures he had collected his whole life, which must be a considerable fortune. We really made the right decision to come here this time!"

Babata exclaimed excitedly.

The more extraordinary the opportunity Yang Yu obtains, the stronger he becomes, and the greater his chances of avenging Hu Yanbo in the future.

"We're really lucky. Let's see what treasures Shilan World Lord has left us." Yang Yu smiled and walked into the palace.

According to the instructions, the entire treasure trove of this Shilan World Lord is located in the Treasure Vault behind the palace.
