The appearance of Bigu Pill greatly alleviated the famine problem of ordinary people.

Lin Xiaoquan felt that the classmates around him were relaxed, and he also heard a lot of jokes made by everyone:

"It seems that I am going to cultivate immortals, and I have already started to open the valley."

"I'm an ordinary man, but I still can't help but miss the deliciousness of whole grains!"

"Can this lose weight? I'm finally on track to lose weight! ”

"Do you still need to lose weight? I've been so hungry for the past few months that my vest line is coming out! ”

Koizumi listened silently, echoing with a smile on his face, and he still couldn't help but feel sad in his heart.

With the advent of Bigu Pills, it didn't take long for the canteen to stop selling hot meals normally, and only Bigu Pills were sold.

Bigu pills are also divided into several kinds, the most basic and cheapest is the first batch of free distribution, Koizumi has never dared to eat it, but I have heard the classmates around me describe that the taste is not very good, and even a little bitter; Later, Bigu pills with different flavors were added, and the price was naturally higher.

In fact, the Bigu pills launched later are also synthesized based on the nutrient mud made in Lin Xiaoquan's laboratory. It's just that the addition of specific flavors is also synthesized by the superior after being transported away.

At any time, there are special circumstances, in addition to selling Bigu balls, the school canteen can also order hot meals in advance, but the ingredients are limited and expensive.

Koizumi used to hang out of school on weekends, but now there are not many ordinary shops outside, but there are more small family-style workshops: spinning, garment-making, woodworking, etc.

At that time, Lin Xiaoquan was strolling, and sometimes he felt as if he had returned to his childhood, following his grandmother to the town to catch the market. Everywhere there are people selling handicrafts.

At the same time, in addition to the main classes at school, Koizumi also learned a lot in the life skills classes she elected, and she sometimes took time to take different types of life skills classes with her roommates.

The school also organizes a number of special lectures on a regular basis, and the topics are more practical. For example, this is a wild survival lecture hall full of dry goods.

The main speaker is an officer in the army, who is said to have been in the field army before and has rich experience in wilderness survival. He gave a general introduction to some basic survival experiences from the aspects of determining the direction, collecting food, and finding and collecting water.

Determining direction: In the absence of topographic maps and compass and other standard equipment, it is necessary to master some methods of determining direction by using natural features, such as using a pole or an analogue watch to determine the direction of the sun; You can also use the North Star to determine direction at night when the weather is clear.

In the lecture, some students raised their hands and asked: What should I do if the sunshine is not enough now, and the sun cannot be used to determine the direction, and the weather is not good at night?

Lin Xiaoquan listened and thought about this problem, and the experienced officer then suggested that the characteristics of the ground features could also be used to determine the orientation: large independent trees usually have lush branches and smooth bark on the south side; The ring lines on the stump are usually sparse in the south and dense in the north; Or look at the doors and windows of houses in the countryside and the main entrance of temples, which usually open to the south; Snow cover in buildings, mounds, ridges, and highlands usually melts quickly in the south and slowly in the north. Large rocks, mounds, and trees are densely planted in the south, while moss grows in the north.

After the officer finished talking about the first aspect, it was already getting dark, so he agreed to continue to explain the second aspect, about the way to survive in the wild and obtain food, at the same time tomorrow.

The next day, the officer continued his explanation, and he explained it clearly:

"In the wild, we need to get food, and generally there are two ways: one is to hunt wild animals, and the other is to gather wild plants.

To hunt wild animals, we must first know the habitat of the animal, grasp the life rules of the animal, and then take the methods of pressure hunting, trapping, trapping card and shooting. This requires a long period of training and practice under the guidance of experts to truly master it. Don't try it—"

The students who listened carefully below immediately burst into laughter, not to mention, if the officer did not explain so much, many students who had been hungry for several months really wanted to try it in their hearts.

"Let me briefly introduce the types and methods of edible insects and edible wild plants.

The insects that people eat in the world are snails, earthworms, ants, zhili, crickets, butterflies, locusts, grasshoppers, lake flies, spiders, praying mantises, etc. Although people are not accustomed to eating insects, and even feel disgusted, they will not try it as a last resort in order to maintain their lives, maintain their combat effectiveness, and then complete their tasks. However, it should be noted that in fact, it should be cooked or roasted thoroughly to prevent the parasites in the insects' body from entering the human body and causing poisoning or disease. ”

Hearing the officer say this, Lin Xiaoquan's thoughts couldn't help but drift to the Bigu Pill.

"Common edible insects include locusts: soaked in soy sauce and roasted, boiled or fried; Praying mantis: roasted or fried after winging, boiled or cooked; Dragonfly: edible after dry frying; Cicadas: eaten raw or dry-fried, larvae can also be eaten; Centipede: Dry-fried, but not in good taste; Longhorn beetle: larvae can be eaten raw or roasted; Ants: stir-fried, delicious; Spiders: remove the feet to roast; Termites: can be eaten raw or fried; Pine caterpillars: roasted food. ”

"Huh————" Hearing the whispers of many students around him, Koizumi was amused and worried: I wonder what will happen to them when they know that the Bigu pills they eat every week are these insects.

Although the officer was talking on the stage, he clearly knew the reaction of the students in the audience, and he ignored it and continued to preach:

"Edible wild plants include edible wild fruits, wild vegetables, algae, lichens, mushrooms and ferns. The identification of edible wild plants is a staple of bottom-up knowledge in the wild. China's territory is vast, suitable for the growth of various plants, of which there are about 2,000 kinds of edible ones. The common edible wild fruits in our country are: mountain grapes, Dusi, black blind fruit, thatch berry, sea buckthorn, torch fruit, myrtle, bearded seed, black rice tree, emblica, etc., especially wild chestnut, coconut, papaya is easier to identify, is the best food for emergency survival. Common wild vegetables include bitter herbs, dandelions, houttuynia cordata, purslane, spiny grass, camellia, wild amaranth, broom green, water chestnut, lotus, reed, moss, etc. Wild vegetables can be eaten raw, stir-fried, boiled or boiled.

However, the average person needs to be trained for a certain amount of time under the guidance of an expert to master this knowledge, and here is one of the simplest ways to identify the poisonous and non-toxic wild plants for use in emergency situations. Usually the collected plants are cut into a small opening, put in a pinch of salt, and then carefully observe whether the original color changes, usually the discolored plants are inedible.

Koizumi's eyes lit up when he heard this, and he worked hard to write, although he grew up in the countryside, Koizumi felt that his knowledge of wild vegetables was pitiful. While Koizumi was writing, her keen mental power sensed that someone was paying special attention to her. She couldn't help but pause, but she still kept her head down and continued with her hands.
