Sure enough, at this time, Yang Kong, who was an instructor, spoke.

His voice was faint, with an inexplicable sigh, as if it had come from a long time.

"Almost all of the crops grown here are from pre-civilizations, mainly potatoes."

"To pick out the crops that belong to our time, there is only one kind of crop, which is based on the seeds left over from the previous civilization and has been successfully transformed by several generations - Huangsu Valley."

"The transformed yellow millet grain has not improved its nutritional value, and there has even been a regression in nutrition and taste, but the yield is comforting."

"So, the pre-civilization was great."

"But so what? Such a desirable era, after all, it has fallen. What we are left with is an era in which everything is changing. Changing animals, changing plants, even us humans are changing, even bigger changes! ”

"It's bleak, isn't it? We want to follow the pace of the former civilization, but it is disappearing faster and faster, and the ruins you see are not occupied by patches of mangroves? Until one day, the shadow of the former civilization will finally be gone, and maybe only some cultural relics will be left for us to mourn. ”

"I'm sorry, these feelings shouldn't be what a sane instructor should say in class."

Speaking of this, he put his hands in his pockets and stood beside the teenagers.

Despite their efforts to calm their emotions, the teenagers looked sad and uneasy.

This era is a civilization with no sense of security and storms, and when you think of the fall of the previous civilization, everyone will rise up with a kind of sympathy.

People are very selfish, but no matter how selfish they are, they can't eliminate the attributes of the race that remain in the soul as a race, and at a certain moment, they will put aside life and death to sacrifice for the race.

"But the good thing is that we still receive gifts from previous civilizations."

"For example, the seeds of these precious crops." After sorting out his emotions, he spoke again.

"But as I said earlier, this era is a time of change, and the biggest change is that evolution has become accelerated and unpredictable, making it difficult for humans to intervene."

"So, if you plant these plants outside the Hope Barrier, you might end up with poisonous wheat, hard, unpalatable potatoes, or apples that make you sick if you eat them."

"Of course, more than 90 percent of the results are that these seeds, which have been left over from the previous civilization and have been preserved with great painstaking efforts, cannot survive in this era of fragility at all!"

"Think about it, the heat, the cold, the unpredictable, the ubiquitous, the pollution of the components that are difficult to analyze, they are no longer adapting to the environment."

"And we, who are struggling in this era, have not yet researched crops that are more suitable for this era, crises are everywhere, and we do not have the environment to devote ourselves to research."

"This kind of achievement in Huangsu Valley is already the limit of the No. 17 safety zone."

It's very uncomfortable, Tang Ling heard this, pursed the corners of his mouth, clenched his fists, and his whole body was filled with only uncomfortable feelings.

The sorrow of all this is a sign that human beings will eventually be outcasts of this era?

The next words, there is no need to say Yangkong, everyone understands.

If you want these crops to survive, you can only do it within the range of the Hope Barrier, the purple light of the Ten Thousand Energy Stones!

Because of its energy, acting on the living body makes the living body stronger.

Then come to think of it, it's the only place here.

It is also because of this that the meaning of the Hope Barrier becomes profound again. How would the people of Safe Zone 17 survive without the farm here?

A lot of speculation only became clear at this point.

For example, the source of food in Safe Zone 17? After all, anyone who has lived here knows that hunting and gathering meat and wild fruits are not the 'staple food' of Safe Zone 17, and even the former settlements will receive 'nutrient blocks', what is their source?

After Tang Ling gained knowledge, he had guessed that there must be some farm hidden in the forest, but who would have thought that it was on the edge of this battlefield? Covered with white light, such an insecure place?

"I said, 'Where did the apple I eat grow?' I don't see an apple tree anywhere else! At this time, Auston also suddenly realized.

Tang Ling glared at Auston 'viciously', the guy who can eat apples - despise him!

But Andy was unusually uneasy at this time, and he said in a panic: "There are people working on this farm, me, me, my parents..."

Andy was born in the outer city, and when he was a child, he wondered where the other adults were going to be busy every day in the crowded security zone 17, except for the adults who were doing business. What is the way to get the daily food and clothing?

Did you go hunting? But I didn't see my prey, and I couldn't imagine that I had to get out of the safe zone.

Adults seem to be secretive about this and don't want to talk about it.

He never imagined that one day the answer would be presented in such a way.

If Mom and Dad were also working in it, they would not know that there was such a cruel battlefield not far away, and the 3D holographic projection 'deceived' everyone, and they must have seen the truth when they were working in that 'glass house'.

Thinking of this, Andy's whole body couldn't help but tremble, and tears also appeared in the eyes of Vivian on his side, because she was also born in the outer city, what Andy could think of, how could she not think of it?

"No, I'm going over there, I'm going to..."

Tang Ling sighed in his heart, although he didn't agree with Andy's impulsiveness, he couldn't watch Andy lose control indifferently, in the hope barrier with such strict rules, what if he lost his identity as a crescent warrior in trouble?

After all, Andy was the first to show kindness to Tang Ling.

Therefore, Tang Ling took a diagonal step, wanting to hold Andy, but he didn't want someone to be faster than him at this time.

With a 'snap', Amir slapped Andy in the face, knocking Andy, who was a little agitated, to the ground.

He still wanted to make a move, but Tang Ling grabbed his hand.

At the same time, Tang Ling also grabbed Andy.

"Who do you have to say you don't want Mom and Dad here? I really hate that. Without waiting for everyone's questioning, Amir suddenly raised his head.

Beneath the messy sea that almost covered his eyes, Amir's somewhat beast-like cold eyes showed anger.

Tang Ling's hand loosened slightly, he knew Amir's mood.
