Indeed, it can be understood.

Although it takes at least a few minutes to understand it, it takes at least a few minutes to think about it, and you have to know something.

The simple analogy is like boiling a pot of water, which requires heat.

The most primitive way to throw out the various heat-generating mechanical instruments of the pre-civilization also requires a bunch of combustibles, and then make a fire, use the combustibles to keep the fire burning, and use the heat of the fire to boil this pot of water.

This is a transformation of energy.

In this, the heat of the fire inevitably spreads to the surroundings, so it takes time to boil a pot of water, rather than the heat of the fire instantly spreads to the water itself, so that it immediately reaches the boiling point of 100 degrees.

This is not an accurate analogy, but it is apt to illustrate the problem of energy conversion rate.

So what does the sky express about the universal energy stone?

The simplest and crude way to put it is that you want to boil water, put a pot of water on the universal energy stone, and you use your spiritual power to define that its function is to boil water, then the universal energy stone can provide the heat energy of boiling water.

And in the process, this heat energy only acts on water, does not spill and waste, and achieves a 100% conversion rate.

It's crazy, okay?

The teenagers present who were able to enter the first reserve camp all had a knowledge base, and when they thought of this, their faces instantly turned red!

It's just something like a joke, and if you don't say it in the air, who would believe it?

In addition to that, what can it do to life?

This is more like a joke, like being injured, using mental power to tell the magic stone, healing the injury...

If my thinking is divergent, hungry, thirsty, and more 'mysterious', my vitality is almost exhausted, and I still want to live...

At the thought of this, even Andy, the most timid of all, looked at the huge purple boulder, and his eyes turned red.

"What are you thinking?" Leaning against a pillar on the top edge of the watchtower, he couldn't help but sneer when he saw the excited faces of these teenagers.

Come to think of it, they should have amplified the effect of the universal energy stone on life.

"There's none of your cranky ones. For living beings, its only role is to provide energy, energy to make living beings more powerful. ”

"But as you remember, this panacea stone is amazing, and it's also very violent. I think Tang Ling should have some experience of this. Its body, with our current strength, there is no way to cut and reuse it, the only thing that can be used is the energy it emits. ”

"I mean the purple light." After saying this, Yang Kong stood up straight, and then looked at the teenagers solemnly.

"Therefore, you should understand that the Barrier of Hope exists to occupy this place of light! Guard this 10,000 energy stones! The same is true of your duties! No matter how many dangerous beings this 10,000 energy stones attract to gather here, and if we want to fight for it, we can't back down in the slightest, because it is the hope and heritage of Safe Zone 17. ”

"Yes!" The teenagers took on this responsibility with their hands behind their backs, standing up straight.

And Yang Kong nodded, and at this moment took off the badge on his chest and walked in front of the teenagers.

"So, let's get started. As your instructor, the instructor who gave you the first lesson. On my behalf, I hope that the Barrier will formally empower you. ”

"After the authorization, you will better understand the meaning of what I said before." Yang Kong said.

And the teenagers were a little excited, after the authorization, does it mean that those obstructive white rays will disappear, and they will see the whole grand barrier of hope?

The so-called authorization ceremony is very simple.

The specific process is to use your own badge and the boys' badge to press each other in the sky for about 10 seconds.

In this way, the chip hidden in the Boys' badge will record the information sent by the chip in the Celestial Badge, and when the Celestial Badge officially confirms this information through the badge, the badge permission worn by the Teenagers will be officially activated.

In the process, Tang Ling noticed a detail, when transmitting information, the second star on the left edge of the badge would be pressed in the sky.

At the end of the confirmation, the biggest star on the badge was pressed.

Tang Ling himself couldn't say why, he had to remember these inconsequential things, but it should be useful later?

"Your clearance has been activated, wait two seconds. Then you can see the Barrier of Hope. A reminder from Yang Kong interrupted Tang Ling's thoughts.

Two seconds later, the sound of teenagers inhaling could be heard from the top of the watchtower.

There was an idea of what the Hope Barrier looked like.

On top of the concept, they also saw its three-dimensional image through the teaching projector.

But when I really saw this 'behemoth' that took 90 years to build, the shock in my heart was still indescribable.

In the sun, in the purple rays.

Stretching for thirteen kilometers, the barrier built close to the cliff wall of Hope exudes a colorful light.

In the light, the camp at the top edge of the rampart, the steel cable belt, and the artillery array were filled with a sense of iron and blood.

On the steel cable belt, the fighters with electromagnetic armguards went back and forth.

Below, large wagons carrying various 'harvests', such as the corpses of beasts, etc., resembling pre-civilization trains, are entering and exiting through a gate at the bottom of the Hope Barrier.

And in the midst of this busyness, a large area of green, representing the green of hope and life, unexpectedly occupies the eyes.

The Hope Barrier, the 150-meter-high Hope Barrier, except for the bottom 50 meters, which is made of a thick metal wall similar to the inner castle wall, and the upper 100 meters, are all made of a material that is supposed to be glass, but with subtle differences.

Therefore, when you look at it at first glance, it will exude a colorful crystal light, which is beautiful.

After these glass walls, starting from the bottom of the glass walls, every ten meters of ascent, there will be a huge platform, which also spreads thirteen kilometers, and what is the platform?

All of them were planted with various crops, and the farm could be seen dimly, and many people were busy in it mixed with warriors.

The same is true for the top platform, except that within fifty meters of the top platform near the outer edge, there are a large number of barracks, which is what the sky calls a patrol place.

Hope Barrier, its essence is more like a farm!

No wonder... No wonder...

The teenagers were speechless in shock, but there was also a sense of absurdity in their hearts, who came up with a genius idea? Build your farm on the edge of this turbulent battlefield?

Aren't there a lot of land for seat belts and sub-seat belts? Why don't you use that land? Painstakingly building land and 'glass houses' to grow these crops?

Of course, at the same time as this thought came to mind, as long as you are not a fool, you should be able to think that all this must be related to the Ten Thousand Energy Stone!
