"It's okay, is there a problem?" Ilan quickly regained his attention and asked in a gentle tone. She has always kept her face upright and maintained a serious instructor image, but now there are students who follow her instructions and say something, she is not good to be cold again, after all, she must be a little encouraged, and there will be more teacher-student interaction in the classroom in order to teach and learn from each other.

"I would like to ask if we need to figure out how to solve today's lunch and dinner on our own?" The man asked.

Yilan secretly said that this person is a good partner, and teachers who like classroom interaction must like such students. She nodded: "Yes, the restaurant does not provide nutrients today, and if you can find the ingredients later, you will have the opportunity to learn how to process the ingredients and process them into food; If you can't find it, learn how to carry your hunger. ”

After speaking, Yilan took the opportunity to glance around the classroom, and the students still had that respectful, serious and serious expression, not seeing how much her indifferent threat deterred them.

"I'm done with my question, thank you, instructor." The students who asked the questions were full of energy, and the voices filled the room.

"You may be seated."

"Yes, Instructor."

Ilan is getting bigger and bigger, if everyone asks questions with this process, she won't be able to take this lesson, no wonder this teaching method is in vogue in the army from time to time, and the rules are too big to sit together and answer each other, which destroys the rhythm and train of thought in class.

"You don't have to stand up when you ask a question, you don't have to report to me, just say something." Ilan couldn't help but explain. Although this is not conducive to establishing the dignity of the instructor, it always ensures the continuity of the course.

She paused, recalling what she had meant to say. He continued: "Today's nutrition class is not to teach you how to eat well, but to teach you how to eat well. Nutrients that we use every day. It is processed from various ingredients. These ingredients were originally wild and later cultivated on a large scale. When we don't have nutrients, try to search around us. In addition to the nutrients, all the ingredients in the recipe are also edible, and if you can find their wild resources, you can solve the urgent need. There are two questions here: First, how to identify wild ingredients? 2. How to process wild ingredients? ”

Ilan began to talk eloquently: "There are so many ways to handle the ingredients. But you only need to learn the most primitive and basic methods, which is not difficult, and you will have the opportunity to try it later. I would like to remind you of some of the things you need to pay attention to in the process of identifying ingredients. ”

"Before you start identifying. Two words to keep in mind first: prudence. Paradoxical species are everywhere, they look very similar on the outside, but they contain different ingredients, and this subtle difference sometimes only causes nutritional deficiencies. Even more unfortunate times. It can kill people directly, so if you are not 100% sure of wild ingredients, you must not try them lightly, or even touch them easily. Many animals and plants are highly poisonous, so we must be cautious. ”

"I would also like to remind everyone that the impact of the environment on living things is very important, and that it is a safe food to grow in one place. It may not be safe to change the soil and water quality climate around it. It can be mutated by exposure to light or radiation. Therefore, even if you find an ingredient that you are familiar with, you should proceed with caution. ”

"You all have field combat guidance materials in your hands, and the wild food database in it includes most of the animals and plants in the Edu Star Zone, which is a good tool for identifying ingredients." Ilan was a little embarrassed to say this, because the compiler of the database had her name on it, and it felt like a teacher was selling his own books to the students.

"Report to the instructor."

Ilan looked over, it was not the student who spoke before, it seemed that there were still many people who were willing to ask questions in class. She nodded, motioning for the man to continue.

"Just now you said that it is not necessarily safe to change the ingredients, does it make sense for this database to be used in other star regions?"

"Before I answer your question, I would like to make a point first, if you find a wild ingredient in the database in the Edu Zone, don't just assume that it is safe. Changing places, it can refer to changing star regions to change planets, or it can refer to changing from this island to the base, or even from here to the beach, what you really need to pay attention to is the environment around the ingredients, whether artificial or natural, and it is necessary to examine whether the environment contains obvious factors that induce mutation. Now, back to your question, this database is still relevant for use in other star regions. Of course, because it doesn't fully cover the native resources of other sectors, some of the plants and animals you find in other sectors are likely to be considered unrecognizable by the database, and may be edible or highly toxic. ”

The man looked at Ilan and said expressionlessly for a while, "Thank you, instructor." ”

Ilan guessed that the man must have muttered in his heart, and she said it as if she didn't.

She sighed secretly, and continued: "About this database, there is another thing to remind everyone, sometimes the species image input query, it may give several similar results at the same time, in this case, it may be that the resolution of the image data you took is not high, then according to the requirements of the database to shoot a few more times, if there are still more than two matching species, that is, the similarity between these species is extremely high, and the database cannot distinguish it by images alone." At this time, you can carefully study the text descriptions of each species, distinguish them by yourself, or directly check the food safety level of these species...... Just decide for yourself. ”

The thirty people were all dumbfounded, and Ilan was helpless, she didn't want to be like this in class, everything was just possible, there was no definite statement, but she couldn't help but say it. This group of people has no concept of wild ingredients at all, so they point to this database for rescue, of course, she has to explain the details of the use of the database in detail, lest they be in a hurry and don't know what to do.

"Instructor, this database is not powerful enough to be fully trusted, is there any other way to identify it?" A student said with a frown.

Yilan sighed again, the elite's thinking is fast, and the criticism is direct, and she is about to talk about other auxiliary identification methods.

"Yes, you can observe the animal's reaction, maybe it helps. Of course, we may not be able to eat what they can eat, but we must not eat what they reject. Elanth paused for a moment and said, "There is no external object that can be fully trusted, and in this case, the only one who can trust is yourself or ...... Luck. ”

This statement was really a toothache, and Ilan noticed that the students were all frowning and looking solemn.

In addition, heating and cooking is always the best way to avoid risks in wild food, many toxins will be destroyed after heating, and the harm to human health should be reduced. There are several ways to heat it, and we can try it out later. ”

"You can also have a meal when you have time, so that your stomach and intestines have the opportunity to adapt to some foods other than nutrients, so that when you are forced to eat wild ingredients, your body will be highly receptive." Ilan couldn't help but be embarrassed when he said this, feeling like he was pulling a weekend order for Triumph Restaurant.

"Still have questions?" Ilan looked around the classroom and said, "If not, disband, and gather in ten minutes." ”

"Yes, Instructor." Thirty people stood together to send Elan.

Before Ilan walked out of the classroom, none of them moved, and all of them were upright. Yilan sighed secretly when she went out, although this class was not good, but the students' respectful posture towards her made her panic and pride, and the word instructor was heavy in her heart.
