Tang Ling's doubts had been there from the beginning, and at this time, he had thought a lot.

Of course, he can think that the back of the Hope Cliff is too dangerous, and those corpses and beasts are all attacking the Hope Cliff day and night.

This does create a security risk.

But why hit the cliff of hope? Wouldn't it be better to go around the Cliff of Hope, from the forests on both sides of the cliff to the front?

Also in order to prevent this, Security Zone 17 has troops in the mangroves on both sides of the Hope Cliff, and the instructor of Arborvitae has revealed this information before.

In that case, why not concentrate the superiority of forces on both sides and build fortifications?

Even if the behavior of these beast corpses is not easy to control, the goal is the Hope Cliff, and the humans outflank it from both sides and clear it from time to time is the best choice, isn't it?

Why do you want to build a barrier of hope behind the cliff of hope, fighting day and night, even at the expense of using the illusion of 3D holographic projection to deceive everyone?

It turns out that both corpses and beasts are commanded by wise people, and they don't always hit the kilometer-high Cliff of Hope, unless...

When I think about it, the answer is about to come out, but it is still cloudy.

There is an absolutely indescribable logical flaw in the middle of this matter, and the root of this flaw is that fools should understand that if the No. 17 safety zone is to be expanded, to expand, the better choice is on the other side of the cliff of hope.

There is no need to spend so much manpower and resources on this side, so what is the answer?

"That's a good question." Tang Ling's question attracted the attention of some people in the command center, and finally triggered the thinking of all the teenagers.

Yangkong directly affirmed Tang Ling's question, obviously this is the focus of his lecture - what is the reason for the existence of the Hope Barrier?

This time, Yang Kong did not stay in the command center anymore.

He led the thinking teenagers to the side of the large circular center, where there was an upward escalator leading to the roof of the command center.

To explain clearly, you must see clearly!

**

The top of the Lookout Tower.

If you stay in the dusty air for a long time, you will feel that your mouth is full of dust.

The smell of blood is fine, but if you get used to it, you won't smell it.

This is the norm of the Hope Barrier, it is the air that belongs to the Hope Barrier, and when you come here, you have to adapt to the air and the smell here.

Coming to the top of the watchtower, this is the first thing Yang Kong said to the boys.

As for what follows, there is no need to say anything.

Because here, they can see everything clearly, they need to observe for themselves, observe this place on the huge ruins, as long as they are not stupid, they will be able to quickly find out what the problem is.

Tang Ling was also watching quietly.

Thanks to some time in the command room before, he got used to the battlefield first, so he didn't have much impact when he really faced the battlefield this time, and even stood on the edge of the top of the Lookout Tower in order to see the world behind the Cliff of Hope more clearly.

Here, the dust will be bigger, and the smell of blood in the wind will suddenly become full of reality, as if the whole person is soaked in blood.

But it didn't matter, I could feel the violent energy fluctuations of the purple boulder in front of me, which was less than 20 meters away from the Lookout Tower, as wide as the Hall of Glory, and reached a height of 14 meters.

Yes, the first thing you see here is this purple boulder, which stands quietly above the ruins.

Emitting a hazy purple light, it enveloped a large area, forming an irregular circle.

This envelopes the entire Barrier of Hope.

Without an explanation from the sky, no one knows what this purple boulder is? It's just that by virtue of the body's instinct, you can feel so 'naked' close to it, and every cell in the body is active, as if it is new.

Even something as illusory as the spiritual will clearly felt a sense of excitement, burning blood positively and devouring fear.

This feeling is not unfamiliar, before in the command center, just sensing a touch of purple light, Tang Ling had a feeling that his cells were active and his desire to fight was boiling.

It's just more obvious now.

He also discovered the battlefield, no, to be exact, all the battles revolved around this purple boulder, and if you looked a little closer, you could see that whether it was a corpse, a beast, or any kind of messy monster, their goal was to rush towards this purple boulder.

The battlefield area divided by the No. 17 security zone is also divided around this boulder, which basically achieves 360-degree airtight protection.

Originally, Tang Ling was very sensitive to purple.

Whether it was Ziyue, who was vague and inadvertently mentioned, or Su Yao's accidental leakage of words, saying that Ziyue had a big secret, it all aggravated Tang Ling's sensitivity.

So when he saw the purple boulder for the first time, Tang Ling knew that the answer he was looking for was probably right in front of him.

With an instinct for precision, he is able to feel every change in his body and even his spirit more than others.

He subconsciously wanted to get closer to this boulder, to find out what this purple boulder was? What is the significance of the purple glow it emits? Is there any connection to the Purple Moon in the sky?

With just his eyes, Tang Ling didn't have the ability to determine something? He used his instinct for precision against the purple boulder.

This is an unprecedented attempt, and it is a subversive use of the precision instinct, which is now characterized by computation, not analysis.

Of course, it will also have the effect of being highly sensitive to danger, but whether this comes from his own instinct or the ability of precise instinct, Tang Ling has not yet figured this out, let alone mastered it.

Anyway, Tang Ling began to try, he tried to 'see' the purple light with his precise instinct, and sensed very vague energy fluctuations.

This was simply not enough to make Tang Ling think about what kind of energy this was? What analogies can be referred to, and then what conclusions can be drawn.

So, Tang Ling boldly condensed his spirit and used his precise instinct to sense the purple boulder.

In just an instant, Tang Ling felt as if his body had fallen into boiling water, and the purple boulder seemed to be able to respond to his induction, and the huge energy suddenly 'rushed' over.

Tang Ling couldn't help but let out a low sigh, his whole head felt a huge dizziness, he retracted the precision instinct on the purple boulder in time, if he allowed that energy to 'rush' over, his body would be supported and exploded.

This was an extremely correct judgment, and when the precision instinct was withdrawn, the violent energy also subsided, but the vertigo made Tang Ling stand on the edge of the watchtower and stagger...

Yang Tian grabbed Tang Ling, looking at Tang Ling's red, bloodshot eyes, he asked very directly, "You, what have you done?" ”
