Wales was silent for a long time.

Evidently, the cheeky words instantly refreshed his worldview.

But having seen all sorts of major spectacles and played tricks beyond the imagination of others, how could he not realize this guy was a problem?

And quite a significant one at that.

This brazen demeanor made it obvious it was up to no good.

"Then I can only rely heavily on you," Wales said with a straight face, though in his heart he calculated that there was a problem here that needed thorough investigation.

Some trouble indeed.

Surprisingly, everything else went smoothly, but on something thought to be problem-free, an issue emerged — encountering such an ambitious Celestial Dao.

Although Professor Wales was not aware of this private group chat, his intelligence led him to guess that these Crystal Wall entities might have some special channels for contacting each other, plotting behind the scenes.

It seems governing these various worlds is a profound study!

This Crystal Series Multi-Dimensional World...

Is not as simple as he imagined it to be.

This world has depths, and he thought he had figured out the "bonfire" mystery and had nearly grasped the world's essence; clearly, he had become a bit arrogant.

To be honest, even though he felt his combat power should rival that described of Ancient Gods, there were always greater powers and skies beyond skies... he still needed to rise steadily here.

And previously, when he didn't engage with Black Star, it showed his prudence.

This old man was just patient because he was so old.

"Firstly, this Thorny World, it's impossible to abandon it..." Professor Wales was somewhat troubled in his heart, "He still had to figure out why it was so."

Continuing on, he strode forward, researching.

In the blink of an eye, more than a decade had passed.

The whole Immortal Dao Divine Country experienced a huge boom, the entire Divine Upper Extraordinary System finally ushered in abundant depth and accumulation.

Various Immortal Treasures, Divine Treasures, Spirit Plants appeared in an endless stream.

After Black Star himself was overtaken in battle by the Emperor, he was thoroughly stunned, reflecting bitterly, and shut himself in to begin re-studying Spirit Plants and Immortal Elixirs of his Divine Upper Level.

Preparing to redouble his efforts and seek revenge on the Emperor.

This is a pure man.

One who is free from low-level tastes, deeply vindictive.

"He's researching new drugs again."

During this period, Professor Wales had completely realized the troubles.

This Black Star was simply a hands-off shopkeeper with only a three-minute passion; he had to step out to help coordinate many matters, establish various systems, and also handle relations with the Thorny World.

Now, with one acting all flashy, and one acting all brazen, he was losing his patience.

If it weren't for Magina and the other two being somewhat reliable, coordinating the entire civilization, he would have been overwhelmed.

But he didn't know the third one dragging their feet was about to appear.

"Your Majesty the Imperial Tutor, we've finally found you!"

On this day, as Professor Wales was out for a stroll, he saw two identical old twin men, wearing military uniforms, carrying cameras, in the guise of medieval war journalists.

Professor Wales had no chance to speak.

"Your Majesty the Imperial Tutor, we are your long-lost, unrelated biological brothers," Wadon suddenly kneeled, "We have the same blood running through our veins!"

Wales glanced at them, his eyes showing confusion, but the old man's temper was still good: "Are you from the Immortal Dao World?"

"No, we are from Earth!"

Wadon quickly said: "Do you have any impression of it?"

"Earth?" Professor Wales took the materials handed over by the other, first puzzled for a moment, then quickly began to look over them.

The information and name of Earth indeed seemed somewhat familiar to him.

It felt like an extremely distant memory.

And the materials introduced a 21st-century Professor Wales, whose photograph resembled him, with titles like bioengineering, spatial technology, mechanical science… It seemed to invoke a very warm memory.

"What is this???"

A sudden inexplicable melancholy arose in his heart.

As a mortal, it was impossible for him to have such a deep memory, having long forgotten much of his childhood and past stories.

But that didn't mean he hadn't left records.

It's just that these memory records were meaningless scrap memories to him.

Not only does it lead to brain overload and confusion, but it also doesn't help my current self at all.

But at this moment, he frowned deeply in his heart, "Earth? I should check my diary, based on what they've said, is it my original self?"

After saying that, he opened the memory files and looked at the scenes one by one.

After a long time, he finally came to his senses, looked ahead, and revealed a look of meeting an old friend in a foreign land, exclaiming, "Wadon, it's actually you? It's been eight billion years, how are you still alive?"

"Indeed!!"

Wadon was overjoyed, "You've been wandering outside for eight billion years, but in our eyes, the flow of time is different, I didn't expect you've already become the ancient top dominator here!"

Wadon and Professor Wales were people from the same era.

Even on the parallel world's Earth, Wadon, as a capitalist, funded this scientist, which led to the founding of the Umbrella Corporation, causing the failure of the serum and the advent of the apocalypse.

It can be said that the apocalypse virus on the parallel Earth's was directly created by this person in front of me.

It can only be said that Ning Guochang transmigrated here and is not on the same level as this transmigrator!

"To meet an old friend in a distant land." Wadon was briefly overjoyed.

"But how are there two of you?" Professor Wales frowned.

"Let's sit down and talk." Wadon quickly said.

So they found a pavilion to sit down, and they gradually learned about the events that happened back then.

Professor Wales talked about the past: "On the Earth back then, the apocalypse broke out, and though we killed many zombies, they quickly entered the Demigod era, very, very quickly."

"In a decisive war, we waged a battle with many Zombie Lords led by Ning Guochang. Although we killed many, we suffered heavy losses and could only leave Earth on a barely-built cosmic spaceship."

Li Qing also secretly pricked up his ears to eavesdrop.

Wales clearly was a parallel universe transmigrator like Ning Guochang!

The second transmigrator!

And not as unreliable as Ning Guochang.

What this old man before us is talking about is the memory of the Earth civilization in the parallel universe after Ning Guochang's death.

"After besieging Ning Guochang, our army was completely unable to resist. The remaining scientists on Earth began to wander, space jumping, wandered for decades, and finally settled on a planet, then continued to improve, opened the Subspace, entered the Demigod level, and shepherded the civilization inside."

"However, some things happened, there was a coup, and I was personally knocked into the Subspace, being shepherded by others."

"As you know, at that time I, as a scientist, had no power to protect myself, and wasn't good at fighting. I was funded by you capitalists and was thrown inside, left to fend for myself for a while. I found a method to break into the Divine Upper level, and upon breaking through and retaliating, the outside was closed off, and I've been trapped inside until now."

His account was very brief.

But the hardship involved can be imagined.

It's just incredibly unlucky, with no rise but successive bad luck encounters.

"Actually, we are from the parallel Earth." Wadon hesitated for a moment, and then spoke frankly, "Our side of Earth didn't experience a zombie apocalypse, was not destroyed, and life is very peaceful."

"I guessed as much. In our cosmos, Wadon has long been dead, but you still exist here, which means you are the Wadon belonging to this Crystal Series cosmos." Wales smiled as if he had long suspected, "Didn't they say, siblings of different fathers and mothers?"

Wadon felt a bit embarrassed and quickly asked, "Do you believe what I say about the parallel universe really existing?"

Wales smiled slightly and said, "I still firmly believe the cosmos is round, my memory cannot be messed up, and this universe is square, which means I've traveled to a parallel universe where there is another you living within the Crystal Series cosmos."

No...

Our Earth is also round!

But Wadon is a smart person, good at climbing up the social ladder, "Indeed, in our Crystal Series cosmos, Earth's civilization is square, and actually, our hometown is not called Earth but Place."

Place!?

Exactly what I thought.

Wales listened and instantly had all his doubts cleared!

Indeed, the cosmos is both round and square.

This Crystal Series cosmos here actually also has Earth civilization.

"Do you believe in parallel universes?" Wadon was surprised.

"Of course, your level hasn't reached it yet; once your realm improves one more level to my level, you'll start to conjecture that the universe is not the only one."

Wales smiled, "You think those powerful Divine Upper-level civilizations in certain universes, those salvaged planets, where do you think they've gone?"

Wadon spoke an obvious truth: "In the Subspace, building new Subspace cities and lands."

Wales spoke words that sent chills down the spine, deeply meaningful, "There are always some abandoned civilizations not kept outside, the land humans salvage and build up becomes another small parallel universe, which is quite normal."

Insufficient resources to build artificial virtual universes.

When people have enough resources, frantically plundering and building a real artificial universe, is it difficult?

This is just a given.
