Although I was curious about the instrument, no one answered the question of Yangkong. After all, what is defense? Such a big proposition is difficult to explain clearly in a while.

Yangkong did not continue to make things difficult for these newly promoted Crescent Warriors. The next moment he said directly: "Many people think that true defense is unbreakable. So what is unbreakable? Could it be that a metal cover can cover everything?"

"No, the real defense has already had a very clear concept in the former civilization, that is, sustainable, without blind spots and blank areas, and strict monitoring."

"For this reason, the former civilization invented satellites. You can understand this concept by reading the books left by the former civilization. I will not extend it."

"So, the real defense is a pair of eyes that are within the scope of defense that can see everything and not close your eyes."

"On this basis, the concept of defense extension is to make accurate judgments in a timely manner after discovering any abnormal movements, and then make the necessary responses."

Yangkong never disgusted with the teenagers' desire to learn. In fact, the truly powerful person in this era is definitely not simply amazing force.

Furthermore, if you do not have a foundation of understanding of knowledge, you will not become a powerful person, at least you will not be able to overcome the third level threshold...

I have to say that Yangkong's narration is very precise and moving, and Tang Ling also deepened his yearning for the power of knowledge that turns decay into magic.

Think about it? Such a pair of ‘eyes’! This must exist because Tang Ling experienced the night of the corpse.

He knew very well how quick the response in the No. 17 safety zone was.

Then, this large super-tech instrument is...

"So, the instrument you see is related to defense, and creating illusions is considered a side branch of defense. It is by no means its entire function."

"It's still those eyes!" Auston was a little excited, but he didn't expect that there was something like this in the safety area No. 17.

Smiling in the sky.

"It can also make judgments on any situation." Christina's mood also became high.

Yangkong still smiled.

After a moment of silence, he said: "To be honest, it is the 'eye' and can make the most correct judgment of the situation through precise calculations. On this basis, it can also create illusions and produce a shielding effect. Finally, it can also make accurate reactions, such as precision strikes. A very powerful precision strike."

"Its complete name is the second-level fortification body! It is also called the second-level moat."

Powerful, so powerful that it makes people desperate.

This is Tang Ling's first reaction. If the No. 17 safety zone has such a thing, and if he has to stand opposite to the No. 17 safety zone one day, will he still have a half-point chance to win?

That night, that night's sword light, all hatred, the No. 17 safety zone cannot be separated from it.

Even after more than a month, I inexplicably recognized some people from the No. 17 safety zone.

Tang Ling couldn't forget hatred.

But the view has become that some of the high-level buildings in the No. 17 safety zone have their hands stained with blood from the lives of people in the settlement.

What if this instrument is used for some high-level buildings?

Tang Ling's heart was filled with anger and despair. Under the calmness of the surface, he was his clenched fist in his pocket.

No matter what, he can only move forward.

Yes, Uncle Su Yao is there to accompany him.

No one knew that Tang Ling had such a violent mood at this time, and everyone was just shocked again.

The real world has been opened anyway, and it is much more shocking, so I slowly accept it.

"This second-level moat is one of the foundations of the No. 17 safety zone."

"After you know that it exists, you will also know why the battlefield behind this cliff exists."

"You must know anyway." Seeing that the teenagers were so interested in the second-level moat, Yangkong said a few more words without missing the opportunity.

As soon as these two sentences were spoken, Yang Kong felt a deep fatigue in his heart. When will this endless battle end? At least now he can't see the light of hope.

How long does it take for the group of teenagers who are curious about everything to feel as tired as him?

Three months? Half a year?

While Yangkong was pondering, Auston and his men were already excitedly discussing the battlefield. At this moment, a vibration came from the iron cage.

Finally landed.

Is this the battlefield? Everyone has straightened their bodies after the iron cage lands.

The excitement brought by the second-level moat made them temporarily forget the reality.

But after landing, recalling what he saw on the cliff before, these newly promoted crescent warriors quickly recalled reality.

Fight against those huge monsters? Are you going to fight immediately? How can we fight? What should we do? Will we die?

These were inevitable thoughts, and even Tang Ling couldn't help but feel nervous.

The heavy appearance of the Arborist instructor before is still in front of him. Will the so-called 2-to-1 mortality rate of the First Preparatory Camp start from now on?

Looking at the appearance of these crescent warriors, Yangkong seemed to find it a little funny.

But in the same way, he did not open the iron door, but stood seriously behind the iron door, in front of the young men.

"Now, I want to formally introduce myself, I, Yangkong - the instructor of the introduction to knowledge of the first preparation camp."

"From waiting for me to open the iron gate, you will learn the first lesson of the First Preparatory Camp."

"I will explain to you the basics of the 'Barrier of Hope' and the 17th safe zone. This is what you must know as the first reserve battalion, the reserve warrior with the title of Crescent Warrior."

“Teaching time is one hour.”

"Then, let's start now." As he spoke, Yangkong reached out his hand, opened the safety plug, and suddenly pushed open the door of the iron cage.

"Ah..." Wei An couldn't help but let out a low voice, closed her eyes, and shrank her body, as if she opened the door in the air, and she would see the bloody battlefield and a terrifying monster rushed over.

The others couldn't help but feel very nervous and retreated slightly.

Although Tang Ling was standing closest to the door, she also swallowed.

"Haha." Yangkong couldn't help laughing. This is a 'funny drama' that is staged every year, and the best Crescent Warriors of this year are still the same.

Amid the laughter, Yangkong walked out of the iron cage casually, then put his hands in his pocket of the uniform, waiting leisurely for these newcomers.

Tang Ling blushed slightly. When did he start to become afraid? He tried hard to maintain his calmness and followed him out of the iron cage without waiting for a second.

And the moment he walked out of the iron cage and saw clearly everything in front of him, he couldn't help but be stunned on the spot.

Except for a small open space facing the cliff in front of me, the rest of the place was covered by white light and nothing could be seen.

It's like a covered world.
