Yang Yan saw that some people were a bit confused, so he explained:

"The ten of you working together form this sword array, which can advance offensively or retreat defensively; it's a sword array full of lethal moves."

"If each of you can comprehend and cultivate it to great success, even if Half-Step Demon God Chiyou reappears, you can surround and trap him! You might even be able to wear him down to death!"

"Tch!"

Upon hearing this, Ao Tian immediately scoffed on the side.

Yang Yan turned his head to look over, but Ao Tian acted as if nothing had happened, concentrating his eyes on his nose and his mouth on his heart.

"Jing Hong, the Demon Race is coming soon, you must quickly familiarize yourselves with the sword array. Once you reach minor achievement, practice on him!"

"I think he would be very happy to help you improve quickly, wouldn't you, Ice Emperor?"

"Yes!"

The ten swords responded in unison.

Ao Tian, in such a situation, awkwardly chuckled, scratched his head, and helplessly said:

"Uh! Well, of course, I'm just a sparring partner, right? No big deal, no big deal. I'm just curious to see how powerful your sword array really is."

He said this so lightly, but whenever Ao Tian faced the Immortal Slayer Sword Array cultivated to minor achievement by the ten swords, he would recall and wish he could slap himself a few times.

He thought his lifetime of prestige had been ruined just like that!

"Alright, for now, what I need to do is wait."

Yang Yan finished speaking, leaving behind a slightly thin back figure.

Ao Tian also left.

The ten swords urgently began to comprehend and practice the sword techniques. 𝘧𝓇ℯ𝑒𝓌𝑒𝑏𝓃𝘰𝘷𝘦𝘭.𝒸ℴ𝓂

The war of ancient times had passed by thousands of years, and the inevitable great war between the Human Race and the Demon Race had been ignited once again.

The Demon Race, once driven away, now returned with overwhelming power.

And Yang Yan, was he confident enough to lead the Hidden World's forces to resist them?

Honestly speaking, he wasn't sure.

All he could do was train constantly, in a vain attempt to take another step closer to that mysterious Divine Realm.

He had a premonition that even a small step forward could cause this battle situation to change dramatically!

During this period, all the families of the Hidden World quickly sent over the list that Yang Yan needed.

Currently, there were a total of thirteen thousand four hundred and eighty-one people with sect-level strength and above in the Hidden World!

Over seven thousand at the initial sect level.

Over four thousand at the mid-sect level.

More than a thousand at the late sect level.

And at the sect level complete, just below the Titled Powerhouse, there were over eight hundred people!

This was the entire force that the vast Hidden World was currently able to count on!

This did not include those experts who were reclusive from the Hidden World, nor the secret forces deliberately hidden by these families.

And Yang Yan was certain that every family had such secret forces, which were absolutely the elite among the elite.

Perhaps this was the only thing he could find solace in.

Furthermore, at the Emperor-level, the list from these families of the Hidden World had three hundred and one at the initial level, one hundred and twenty-eight at the mid-level, and forty-five at the late level.

Eighteen were complete at the Emperor-level!

This is after a large number of ancient ancestors in the Hidden World had died!

It could be seen how deep the heritage of these families in the Hidden World really was.

Of course, most of this top-tier power came from those top families in the Hidden World.

Even slightly more ordinary first-class forces couldn't match up.

This list handed over by the Hidden World gave Yang Yan some reassurance.

At the very least, the Hidden World still had the power to fight!

Moreover, there was one piece of good news: Ao Tian had successfully refined the remnants of Chiyou's Demon Body.

To know, that was a Demon God Body tainted with a trace of divinity!

After Ao Tian completed the refining, he immediately ran to Yang Yan to show off.

He claimed that if he could comprehend the refined divinity, he would at least have half a foot into the Divine Realm.

He could be on par with the former Half-Step Demon God Chiyou!

By then, leveraging the refined Demon God Energy, he might even step directly into the Divine Realm.

Once that happened, extinguishing the extraterritorial Demon Race would be easy for him.

However, regarding Ao Tian's claims, Yang Yan simply smiled and said nothing.

He wasn't that optimistic.

After all, that was too far off.

Currently, Ao Tian could only barely manage to store the refined energy within his body.

He couldn't even refine this, let alone that trace of divinity?

It wouldn't be an exaggeration to call it a fool's dream.

This process would inevitably be a long road.

After all, if reaching the Divine Realm were so easy, there would be too many Divine Realm experts in this world.

Of course, legendary Immortal Gods don't count.

In Yang Yan's view, they were entirely fabricated by the masses, not worth believing.

More than a month had passed since Yang Yan taught the ten swords the Immortal Slayer Sword Array.

Currently, all the families in the Hidden World have dutifully bowed their heads in front of Yang Yan's firm attitude and absolute strength.

As Yang Yan said, now people in the Hidden World basically follow his lead, not daring to disobey.

As all forces in the Hidden World took action, making various preparations for war according to Yang Yan's requirements, there was movement in the outer regions as well.

A colossal, brown-colored planet was slowly rotating in the starry sky.

On its highest peak were several magnificent stone structures.

Looking down, one could see an endless stretch of palaces and huge stone dwellings on the slightly lower peaks below.

On this day, a few squads of Demon Race in black armor suddenly emerged from these long-dormant palaces.

After appearing in a wide training field, these squads of armored Demon Race quickly aligned themselves, exemplifying strict orders and prohibitions.

A rough estimate would be about forty or fifty people.

Then, under the lead of a person who seemed to be in charge, they transformed into a dark light shooting into the sky.

The Demon Race was coming!

Yang Yan had long ago released the news in the Hidden World that the extraterritorial Demon Race would arrive, and now, after so much time had passed, the extraterritorial Demon Race had indeed appeared.

In the sky, bodies continued to fall, and the blood blooms in the air appeared both lonely and cold at this moment.

Severed limbs began to slide around Yang Yan, finally dropping heavily to the ground, covered in dust.

Yang Yan had already arranged for people to guard around the space barrier of the Hidden World, naturally using the experts from those families.

Upon receiving an urgent message today, Yang Yan immediately brought the ten swords and Ao Tian.

However, the war had already begun.

Outside the space barrier of the Hidden World, dozens of fierce and warlike humans were already engaged in fierce battle with a small group of Demon Race.

On the Demon Race side, there seemed to be only dozens of them, each wielding a strangely shaped scimitar surrounded by demonic qi.

The leader appeared similar to the Human Race but had four hands.

Two hands wielded a trident, while the other two each held a similarly bizarre-shaped knife.
