Zombie Crisis: Survival comes first

Feng Yi sighed and said, "It's getting more and more difficult now. Recently, the leaves of the vegetables in the greenhouse have turned a little yellower. It's really difficult to grow. The book says it's quite simple, but it's really not easy to implement..."

After she finished speaking, she stood up and continued to pick up the books on the ground.

Chen Yu glanced at the fallen cabinet next to him, walked over to help flip it up, and then turned back and said, "Do you know what caused it?"

Hearing this, Feng Yi shook her head helplessly: "I'm not sure. It would be great if I could find someone who knows how to grow vegetables. In fact, a lot of the knowledge written in these books is not very careful."

As she spoke, she threw a few books on the table and said again: "In some extremely bad situations, it is impossible to generalize at all. It is easy to waste seeds simply by relying on my exploration..."

"It's already like this anyway, just go ahead and do it boldly." Chen Yu looked at her and said softly.

Then the two of them briefly cleaned the study together, collecting some of the clean books and preparing to find a place to burn the others.

Suddenly, Chen Yu saw a book with a carrot on the cover. He thought of something and turned to Feng Yi and shouted, "Could it be malnutrition?"

Feng Yi was moving a chair. When he heard this, he wondered: "What?"

"I mean, is it possible that those vegetables have not kept up with nutrition and caused the leaves to turn yellow?"

Chen Yu added again.

"Uh..." Feng Yi sat down and thought carefully before replying: "Although the books I have read so far have not mentioned this reason, I seem to remember something."

"Speak quickly." Chen Yu urged.

"I don't know if you have noticed that before the end of the world, some people's hair will turn yellow due to lack of nutrition. Even now, many people will do this." Feng Yi said seriously.

"Pa!" Chen Yu snapped his fingers: "Yes, since people's hair will change color due to malnutrition, vegetable leaves should also be the same. Speaking of which, what kind of fertilizer do you apply to them?"

Hearing this, Feng Yi frowned and shook his head, spreading his hands: "Nowadays, people cannot achieve balanced nutrition. Where can I find fertilizer..."

"Strange, are there only a few tomatoes?!" Chen Yu was stunned and said curiously.

"Yes, just those few, most people have never tasted it."

Hearing this, Chen Yu rubbed his palms and walked back and forth in the room, and then said again: "Don't we have half a bag of fertilizer?!"

Feng Yi nodded: "Yes, there is, but no one knows what it is, and I don't dare to use it easily."

Yes, even someone as familiar as her couldn't recognize her, and Chen Yu didn't even recognize her.

"At that time, the words on the bag had almost disappeared. I just saw the word fertilizer and thought it would be useful, so I brought it back directly..." Chen Yu sat down again and said a little irritably.

Nowadays, the problems are in front of him one by one, and he must find a way to solve them in order, otherwise if something happens at the same time one day, it is likely to cause more serious consequences.

Feng Yi also sat there quietly, waiting for Chen Yu's next words. Although she liked reading books on this subject, it was two different things from actually doing it.

More than a minute later, Chen Yu patted his knee and asked hurriedly: "What kind of vegetables are there in the greenhouse?"

"Two kinds, the others are dead, tomatoes and cabbage..."

After receiving the answer, Chen Yu began to hope that the answer would be the same as what he expected. Now he regretted not protecting the old man.

If nothing else, that old man must know how to grow vegetables. With such a person in the end of the world, many things will be much easier.

But it's a pity that things have already happened, and there is no point in regretting anymore. Now we have to do the current things well.

Then Chen Yu asked again: "Then do you know what two kinds of fertilizers need to be applied to these two vegetables?"

After finishing his words, he looked at the opposite side expectantly...

"What a coincidence, I happened to know it." Feng Yi smiled bitterly and replied: "Potassium fertilizer is fine, but I haven't seen it before and I can't recognize it."

"Potassium fertilizer..." Chen Yu stood up and repeated these two words. He turned around and shouted: "When will Alei come back?"

"Probably at night, what's wrong?" Feng Yi asked curiously.

Chen Yu waved his hand: "Since he knows how to extract potassium nitrate, he must know that kind of fertilizer, but time is urgent now. No one can say whether more vegetables will die in more than ten hours..."

"Potassium fertilizer...Potassium nitrate..." Chen Yu touched his chin and thought seriously. Suddenly he clapped his hands and said excitedly: "It's very possible that that bag of fertilizer is exactly what we need!"

"Huh?!" Feng Yi didn't quite understand.

Chen Yu snapped his fingers again: "Alei told me last time that he knew how to extract potassium nitrate from that bag of fertilizer. In this case, is there a possibility that it itself is potassium fertilizer?!"

"Are you sure?" After hearing these words, Feng Yi hesitated and said: "Those are the last batch of vegetables in the community. I'm not telling you that if they get soaked to death, we will really be doomed. The further time goes by, the harder it will be. Find these seeds.”

After thinking for a while, Chen Yu raised his head and replied: "I'm not sure, but there's nothing we can do about it. Nowadays, it's no different than before. At that time, when you encountered something you didn't understand, you could just search the Internet to solve it, or you could even ask an expert. "

"But in the current environment, we are just like walking with the lights off at night. We have to be careful every step we take. If you try it, you may be right. If you don't do it, you will keep spinning in circles."

"The big deal is, let's treat a dead horse as a living doctor..." Chen Yu made a fist with his right hand and waved it downwards.

Feng Yi nodded: "In that case, let's go."

After finishing his words, Chen Yu was stopped just as he was about to leave.

"Wait a minute, help me move this box of books first. I don't have the eyesight to see how a girl with such heavy weight can move it..."

Hearing this, Chen Yu walked back, grinned broadly, raised his hands and left.

......

Ten minutes later, the two of them were standing outside the greenhouse holding the half bag of fertilizer, discussing how to apply fertilizer.

"By the way, does it have to be mixed with water?" Chen Yu asked curiously.

Feng Yi shook his head: "I don't know, I haven't tried it..."

The mouth of the bag is tied with a rope, and only the word fertilizer is left on the outer bag.

Chen Yu untied the rope, and then the two of them came closer and smelled it. Suddenly, a pungent smell came, which was very unpleasant.

The smell directly made Feng Yi cover her nose: "I guess it would be better if you add some water. Let's shower one plant first, and then come back and take a look in two days..."
