The age had entered a terrifying period of eruption.

"Haha, other nations!"

"Are we going?"

"We go together! Together!"

The entire Celestial Realm was in an uproar.

In the year 20008 of the Solar Calendar, in order to distinguish between different Cosmoses, the humans of this Cosmos officially named that dimensional Cosmos which had originally been in a superposed state, but whose wave function collapsed after observation, as Cosmos No. 01, also called the Fist Cosmos.

Because it was ruled by a Nokron whose authenticity no one knew.

No one knew who the true mastermind behind the scenes was.

In the year 20010 of the Solar Calendar, war began. Across the lands of the Celestial Realm, the great Holy Lands started cultivating the younger generation to become Outer Domain Celestial Demons—to infiltrate, seize bodies, hide, and lie dormant.

This whole series of brand-new Cultivation Techniques, the infiltration and body-seizing system of the Outer Domain Celestial Demons, was pioneered by them and continuously perfected!

A rough spy-training mechanism was being born.

And the entire history of the Multi-dimensional Universe formally entered a race to hunt enemy spies and to train their own.

A race to see whose Outer Domain Celestial Demon technology was more advanced.

In the year 20009 of the Solar Calendar, the sky was torn open with a gigantic rift. The [Present World] translation channel opened, and thousands of Outer Domain Celestial Demons suddenly returned.

The other side used blitzkrieg tactics to instantly take away this batch of Outer Domain Celestial Demons, and a new second batch began descending along the channel.

When carefully calculated, the entire Celestial Realm had 0.0018% of its Matter plundered.

"Damn it!"

"So my husband had long been dead; he was actually an Outer Domain Celestial Demon in disguise!"

"We simply cannot understand their technology!"

"Those Celestial Demons are hidden too deeply, we simply cannot catch them!"

"Backwards, we are far too backwards. They know all our defensive systems and can specially counter them."

The young people of countless eras were enraged.

They discovered that some of the core personnel, leaders, friends, lovers, fathers by their side... had all turned out to be those Outer Demons in disguise.

By now they had clearly realized that there were other Cosmoses outside their own; they could no longer live in complacent ease!

Many aspiring youths began to tour the streets, delivering speeches:

"Now, the war of the Multi-dimensional Universe has begun. We do not know how many Cosmoses there will be in the future, how many Parallel Universe futures of us... our homeland’s territory is being invaded and plundered."

"Those marauding armies of villains occupy our hometowns and ravage our Cosmos."

"The Cosmos shrinks, our territory is occupied—where can we call home?"

...

In the year 20010 of the Solar Calendar.

Being beaten by the Future Universe without the slightest power to fight back filled everyone with fury.

They began self-criticism, reflection, and an intense search for strategies of war.

"They are too strong."

"Their technology is ninety billion years ahead of us!"

"This is hard power; we simply cannot win."

"What’s more, we are from ninety billion years in their past; all sorts of historical records exist. They are perfectly clear on our various defensive lines and internal structures."

In the academies, countless people were discussing.

Ideas such as "those who lag behind will be beaten" and "learn from the barbarians to control the barbarians" were fermenting among the young, and a vast ideological transformation swept across the lands of the Celestial Realm.

Many young people proposed studying the enemy’s Advanced military technology, seeking a path to strengthen the nation and resist humiliation, using the enemy’s own way to give them back in kind, in order to defeat those invaders from the Outer Universe.

A group of "overseas students" even emerged, planning to infiltrate as students and return one day to serve their country—the idea of such latent spies erupted again and again in the hearts of the young.

In the year 200014 of the Solar Calendar, the first batch of Outer Domain Celestial Demons set out: three thousand powerhouses, counterattacking Cosmos No. 01, the Fist Cosmos.

In the year 200016 of the Solar Calendar, a large number of Outer Domain Celestial Demons failed in their infiltration and were all captured by the other side using Advanced technology. Ta Atabia, the Time God who could cross into the enemy Cosmos, sent back information: "They are all dead. Our survival rate is 0."

"They just left it at that?"

"How is that possible?"

"Each one of them was an elite, one in a hundred million from our training!"

Once this news came out, the confidence of all the powerhouses in the Celestial Realm suffered a heavy blow!

They were the geniuses of the younger generation cultivated by them, all stunning in talent, suppressing their own All Heavens.

The enemy’s infiltrators came with innate entry-level Authorities, hiding in trials so well they could even deceive a Saint.

Yet when their own side infiltrated, they were rooted out with ease.

In the year 20019 of the Solar Calendar, the channel was opened a second time, and they once again infiltrated the enemy Cosmos. Three thousand Outer Domain Celestial Demons were still willing to risk nine deaths for one life and force their way in.

"There is no bloodless war in this world."

"Only by stealing their technology and bringing it back from the Empire do we have any chance of victory!"

The terror of total annihilation did not make them shrink back; instead, it further ignited the anger of this young generation. How could they let themselves be slaughtered like fish on a chopping block?

In the year 20023 of the Solar Calendar, Atabia peered into the enemy’s dimensional Cosmos and sent back a message: out of three thousand, only one survived.

The whole era was shaken.

That was hope.

As long as this person could bring back all of the enemy’s technology.

Even the Saints personally took action, secretly coordinating and designing a comprehensive plan to attempt to welcome his return to the homeland.

In the year 20025 of the Solar Calendar, after layer upon layer of protection and escapes from near-death, the first Outer Domain Celestial Demon belonging to their side finally returned.

This young Hero was bathed in blood. In the spy war, in order to gain the enemy’s trust, he had even killed his own comrades, and those comrades in turn had sacrificed themselves in order to conceal his identity.

He stood upon a high platform, raising the information in his hand high above his head, proclaiming to the world: "This Multi-dimensional Universe is a dark forest. Each one of us is doomed to a life-or-death struggle. These are camps, not right and wrong."

"I am very selfish. I only hope that in the future the ones who die will not be our family and friends, but them—even the other ’us’ in a Parallel Universe. We still have to slaughter them all and scatter their ashes upon the Long River of Time!"

Among those present, some emotional ones were even moved to tears.

Their era had begun to fight back.

...

...

"The development of Civilization is always accompanied by blood and tears."

"This may be yet another Gold golden age of Wizards. Only in war do all sorts of technologies emerge in an endless stream, and all sorts of geniuses brim with hot blood, with tears at the corners of their eyes."

Li Qing sat upon the imperial throne of the Celestial Realm, quietly gazing at this scene of the era.

An era may grow old, but there will always be someone who remains eighteen, still possessing that young, hot-blooded, and courageous heart.

Sylph smiled faintly. "This is hatred being redirected. The Heroes of the previous era had always been rebelling against the lofty Saints because they did nothing... but now these young, hot-blooded Heroes have begun resisting foreign enemies."

This was the transfer of class hatred.

Why would certain evil countries choose to launch a war when their internal contradictions became unbearable, in order to divert attention?

It was precisely because of this reason.

With everyone united against an external enemy and a hated foe in front of them, they naturally would not have the leisure to go after the Saints, to spend their days scheming up all sorts of crazy games.

However, the war of the Multi-dimensional Universe was clearly more Advanced and more dangerous than the previous era of rebellion against the Saints.
