Only a small part of this story is obtained from books, and more parts are guesses filled in by Xiang Nan himself.
There is only this kind of conjecture, and it is more reasonable to connect those fragmented pieces of information.
There is one thing that worries Xiang Nan.
How long can the eternal mystery last? This place traps all the beasts, making them unable to escape.
But what if the eternal secret realm fails? The modern human world is about to repeat the disaster of the ancient civilization.
Xiang Nan murmured a few key words thoughtfully.
Eternal Shadow, Moon Fountain, Eternal Rift, Mist...
After human beings die in the eternal secret realm, they will become eternal shadows. Is there any potential connection between this matter and the reproduction of ferocious beasts
Otherwise, the number of ferocious beasts in the Eternal Secret Realm should have been extremely rampant over the years, and it definitely shouldn't be that I have seen so few.
And here, this small world should be the place where the ancient monks studied the eternal beast.
There is a phenomenon that is easy to judge, that is, the eternal beasts inside are all made of metal, which is completely different from the beasts with flesh and blood outside.
This is a testing ground, but surrounded by so many ferocious beasts, it is very difficult for monks to get out of the tower, let alone research.
This illustrates a problem, there were not so many eternal beasts in the test field back then, how did this overwhelming scene appear.
Many problems have lost the opportunity and method to explore the truth. That era is too long, and it is really difficult to find some clues and information.
Xiang Nan no longer struggled with this issue, not all secrets must find the reason.
Maybe the things in this tower will provide some clues for future warriors. Thinking of this, Xiang Nan dismissed the idea of letting the real body go, and let those tables, chairs, and instruments continue to be preserved.
He returned to the first floor of the tower, looked at the bustling beasts outside the door, and fell into deep thought.
What method should I use to kill those ferocious beasts and obtain their Holy Spirit Stones
He felt it carefully, and found that the eternal beasts in front of him were basically at the fifth level of martial saints. This was an average value. A little higher, for the sixth level of martial arts.
But before, when he came in from the tunnel, he could clearly feel the presence of fierce beasts from the Eighth Level of Martial Saints and even the Heavenly Tribulation Realm.
This once again verified Xiang Nan's previous conjecture that there should be a second layer below this small world.
Those beasts with a higher realm that I perceived before should not be at this level, but at the bottom. My perception when I first came out of the passage confuses the realms of the two levels of beasts.
Looking back now, this is indeed the case. With one's own strength, it is not so easy to defeat a human being at the seventh level of martial arts.
If there were fierce beasts of the seventh level of martial saints in this world, it would be impossible for him to rush into this tower.
So, is the world on the next level filled with ferocious beasts like this
It is still necessary to explore, but with my current state, if I go to the next level, I will die instantly.
It's better to raise the realm first.
Xiang Nan thought for a while, then subconsciously looked at the entrance of the tower.
"When they first came in, Dali and Xiaochong were blocked by some kind of force, but they finally got in, but the beasts outside couldn't get in."
"It must be the Sword of the Dead, which replaced the secret realm's control over Dali and Xiaochong, allowing the two of them to become independent before they are eligible to enter the tower."
"I should be safe here, so let Dali and Xiaochong help me kill the beasts and collect the Holy Spirit Stone."
Dali and Xiao Chong can freely enter and exit this mysterious tower, which is a place they can use.
Thinking of this, Xiang Nan issued an order in his heart to let Dali and Xiaochong rush out to kill the beasts, and when the two of them couldn't hold on, they immediately returned to the tower to rest and recover.
Hmm... that's a good plan.
With a thought in Xiang Nan's mind, Dali and Xiaochong immediately rushed out of the tower.
In such a place full of ferocious beasts, survival is the only key. Therefore, defense has become the main thing, and attack has become secondary.
Based on this, Xiang Nan let Wusheng Sanzhong's Dali act as a defensive role, and let Wusheng 2zhong's Xiao Chong take charge of attacking the beast.
Now Xiang Nan rehearsed the fighting method in his mind, and felt that it was safe, so he really did it.
Da Dali and Xiao Chong rushed out of the tower with a whoosh.
Immediately, an overwhelming number of ferocious beasts rushed over, completely submerging the Vigorous little bug.
In a battle of this scale, combat awareness is the most useless, and there is no room for it to play.
And Dali, under Xiang Nan's command, immediately spun rapidly and turned into a big spinning top.
The extremely crowded ferocious beasts rushed up in large swaths, and were continuously bounced away by force, and bounced again.
One by one, the beasts were ejected in all directions, hit other beasts, and bounced back.
In fact, this effect is not very good, because there is no room for the beast to shoot farther, resulting in a great effort to eject the beast, and the effective movement space that can be vacated is only three meters square.
In this narrow range of activities, there is almost no room for activities.
It is really very difficult for Dali and Xiaochong to fight in such a space.
That Dali was only responsible for spinning, while Xiao Chong saw the right opportunity and immediately killed a fierce beast.
She was as fast as lightning, quickly inserted her hands into the belly of a ferocious beast, and tore the beast in half.
Xiang Nan shook his head regretfully, no Holy Spirit Stone fell out.
Vigorously continued to spin, and the little bug continued to look for the next target to attack.
The cooperation between the two parties is not perfect, and mistakes often occur.
When the little insect was about to attack a ferocious beast, it just spun vigorously, and the beast flew away.
This kind of situation keeps appearing one after another, and it is almost impossible to find a perfect solution.
Not to mention Dali and Xiaochong, there is no way to judge which beast will suddenly be pushed to the front and become his target.
Even the metal beasts themselves couldn't tell.
This is a completely random process, it may not be possible to specify which beast was still behind, but was suddenly pushed to the front.
It's also possible that which fierce beast is still in front now, and will be squeezed to the back in the next moment.
Dali's physical strength and defensive power are consumed quickly, although his speed is astonishing, and the beasts he touches are thrown out.
But during this process, there were still many sharp claws of ferocious beasts that cut through Dali's body again and again.
Rotation has done its best to avoid excessive damage to Dali.
Even so, he still endured nearly forty or fifty claw strikes per second.
In less than ten seconds, the outer shell of Dali's whole body has been scratched clean.
Xiang Nan immediately summoned Dali and Xiaochong back and let them hide in the tower to recover slowly. Observing the results of the battle, Xiao Chong killed a total of three eternal beasts in the past few seconds, but he couldn't even see a single Holy Spirit Stone.
