"Young people are like this nowadays, don't take it to heart." Father Ji sighed and persuaded Mother Ji.

Although Ji's mother was not happy in her heart, she felt a little more understanding when she thought that she was also from Ji Ran's age.

Early in the morning, when the sun was three poles, Ji Ran woke up in a daze, she gently pushed Liu Zhan, and Liu Zhan slowly woke up.

I slept so comfortably yesterday that I woke up late this morning.

"It's getting late, get up quickly." Ji Ran hurriedly put on his clothes and threw Liu Zhan's clothes over.

After Liu Zhan got dressed, he found that Ji's father and Ji's mother had already woken up, but the two of them had not come out of the bedroom all the time.

Thinking of his previous appearance, Ji Ran's cheeks instantly turned red, and Liu Zhan scratched his head in embarrassment, a little embarrassed.

"Don't do this in the future, pay attention next time." Ji Ran said to Liu Zhan.

"Eun, be sure to pay attention next time." Liu Zhan nodded and quickly agreed.

After the family had breakfast, Ji Ran explained to his parents and Liu Zhan about the portable system on his body, although Ji's father and Ji's mother still didn't really understand, but they finally understood something, it turned out that this is a high-tech product from the future, which can be carried with you, and exchange virtual things for real items, and as for how to exchange it in the middle, this Ji Ran himself didn't understand, so naturally Ji's father and Ji's mother couldn't understand it.

However, they understood one thing, the virtual reality exchange system used by Ji Ran was not some strange feudal superstition, but a kind of high-tech from the future.

After understanding this, Ji's father and Ji's mother's hanging hearts finally let go, as long as their daughter was not possessed by a fox spirit, they were relieved.

"Earlier you said that biochemical viruses are future AI robots that attack modern humans? So why do they attack humans? Isn't it artificial intelligence created by humans? Humans are their creators, so why should they take revenge? Liu Zhan asked puzzled.

"Maybe it's because human beings have a lot of human shortcomings? Human beings are greedy, jealous, and like to use violence, these characters make the whole world full of endless variables, and artificial intelligence is a symbol of orderly existence, they need an absolutely stable environment, and human existence just makes this environment not easy to form, so they want to control the number of human beings, right?

Only by reducing the number of human beings to a certain order of magnitude will there be no more destabilizing factors. Ji Ran explained to Liu Zhan.

Liu Zhan was silent when he heard Ji Ran's explanation, although he felt that Ji Ran's explanation was a little unsatisfactory, but, in addition, what was a more reasonable explanation?

If artificial intelligence really wants to exterminate human beings, then there will definitely be no human beings in the future, and Li Han's existence proves that human beings in the future are not completely extinct by artificial intelligence, and Li Han can travel back to the present again and again, helping Ji Ran again and again, which also shows that artificial intelligence does not seem to really have a reason to exterminate human beings, otherwise Li Han would not be able to travel back.

What is it like to destroy humanity and yet always give it hope at a critical time?

Liu Zhan couldn't figure it out, and Ji Ran couldn't figure it out, in short, everything was just a guess and hypothesis of theirs.

"However, in any case, these super biochemical viruses are not ordinary viruses in the movie, they will evolve, and they are more aggressive and powerful than the biochemical viruses in the movie, our army can't stop the zombie tide, we must build this place into the strongest fortress before the zombie tide arrives here." Ji Ran said to Liu Zhan.

"To make this the strongest fortress possible? So how can it be done? Liu Zhan asked Ji Ran.

"Ranran, didn't you say that you can exchange all kinds of materials? Wouldn't it be nice if you just exchanged enough stone to help people complete the construction of the fortress? Father Ji looked at Ji Ran and asked.

"Dad, although the virtual reality exchange system does allow me to exchange for various materials, this needs to be exchanged with system points, I don't have so many points, I can't exchange so many materials." Ji Ran explained to Ji's father.

It turns out that Ji Ran's points are all exchanged for doing tasks by himself, such as cooking tasks, communication tasks, or picking tasks, etc., and the points obtained each time range from ten to several tens, although these points can be exchanged for many materials, but they are still a lot worse than a super project like building a fortress.

"I can only get a few dozen points a day at most, if I want to exchange enough materials to build a fortress, I'm afraid I can't do it without ten days and a half months, and at that time, maybe the zombie tide has already come." Ji Ran said worriedly.

"So what to do?" Father Ji asked with some concern.

"By the way, Xiao Ran, let's see how much food and water can be exchanged for a little point?" Liu Zhan suddenly thought of something and asked Ji Ran.

"I'll see." Ji Ran quickly called up the system exchange panel, and soon, the food and water exchange interface appeared in the system panel.

One point of points can be exchanged for a ton of food and water, the types of food are divided into pastries, cheese, meat, vegetables and fruits, in short, no matter what type of food, a little point can be exchanged for a ton, the same is true for water, pure and drinkable water, a little point can be exchanged for a ton.

Ji Ran told Liu Zhan the information he had checked, and Liu Zhan was very happy after hearing it, and his eyes were full of joy.

"That's easy, what people here lack most now is the means of subsistence, and if we can control the supply of means of subsistence, we can let the people here become our helpers." Liu Zhan said with a look of surprise.

"You're saying that I exchange my points for food and water, and then use the food and water as a reward for letting the people here help us gather materials for various building forts?" Ji Ran seemed to understand, looked at Liu Zhan and asked.

"Very correct, there are many materials here and in the back mountains, which are completely enough to build the fortress, as long as we can make use of the human resources here, we can completely guarantee the construction progress of the fortress, which will undoubtedly greatly accelerate the construction process of the fortress." Liu Zhan snapped his fingers and said very approvingly.
