People are crowded animals, and the more people there are, the more secure they often feel. Zhang Zi'an has camped in the desert, but at that time there were large groups of people, excellent equipment, and powerful vehicles around him. Now he is alone, and his equipment is only the average level of outdoor campers. He walks all depends on his feet. More importantly, there are no large beasts in the desert. As long as the tent is set up, no matter whether it is a poisonous snake or a scorpion, it can be ignored, but in the primeval forest...

In the evening, the fog became thicker and the damp dead branches were difficult to ignite. Zhang Zi'an had to use solid alcohol to help ignite, which was considered igniting the fire.

After that, I still cooked water and cooked. I had to say what was the difference between it and noon, but the canned food was changed and a pot of light tea was boiled to warm the body.

The spotted owl I picked up during the day perched on the tree branches above the tent, and was afraid of the bonfire a few meters away. Its eyes became extremely bright at night, just like two searchlights reflecting the fire.

"Squeak..."

Zhang Zian heard the sound of π, and saw that its fists were clenched all the time. He walked over and opened his hands and saw that blisters had been grinding out of its palms.

π was having a great time playing on the tree today, and even got a little proud. It forgot that its hands were more adapted to the touch of the keyboard than the roughness of the bark, and ignored the fact that it was actually a monkey. Its palms did not have calluses that other monkeys had been grinding out over the years. Its palms were not until it felt hot and burning, but it was not daring to tell everyone because it was its own fault.

Zhang Zian didn't blame it. It was like a child who stayed at home all day studying. It would be strange if he suddenly came to the wild and didn't play crazy.

He picked the blisters on it, disinfected them and applied medicine, and finally wrapped them in a bandage. The bandage skills were very poor. After all, he was not a professional nurse, and it was enough to be practical. But tomorrow π would definitely not be able to shake and swing on the branches, or walk honestly - but this is not what monkeys with long arms and short legs are good at, or go back to their phones.

Other elves were tired after hiking for a day, and even missed the days of taking a bus in the desert - memories always beautify the past, selectively forgetting the fact that the temperature in the cars in the desert is no less than that of the steamer.

"I'm going to eat nuts again? What about fresh vegetables? What about fresh fruits? Do you idiot want me to be malnourished?" Richard dissatisfied with bird's claws and dialed them around the stainless steel plate, which were mixed nuts on it.

"There are freeze-dried fruits, but I don't bring much, so you have to save it." Zhang Zi'an opened a small bag of freeze-dried fruits and put them on its plate, including blueberries, strawberries, mangoes, pineapples, etc. Although the freeze-dried fruits are very light, they take up too much space and cannot bring a lot of them.

Usually, Richard complained with integrity and started eating, but he felt that he had lost face during the day and deliberately found the place back. So he disdained the freeze-dried fruit aside and shouted: "Don't fool me with these freeze-dried ones! The fruits should be fresh to taste!"

Zhang Zian didn't know what it was doing, "If you don't eat it, I'll eat it."

Richard was anxious when he saw him bringing freeze-dried strawberry and mango into his mouth, but he always had to pay a price to get the place back. So he flapped his wings and flew into a nearby herb with beautiful heart-shaped leaves. He leaned his head to peck at the fruits of the plants, and shouted with relish: "Gaga! Sweet, so delicious!"

"Have you seen Bei Ye's survival in the wilderness? In the wilderness, the most authentic way of survival is to use local materials. I look down on the most in the man who enters the wilderness with big bags and small bags!" It shouted smugly.

Most of the other elves are carnivorous animals and have no interest in fruits. Therefore, their clamor did not arouse everyone's envy, jealousy, and therefore it became even more noisy.

Zhang Zi'an kindly reminded: "There are not many plants in the forest that can be eaten, and there are not many that can be eaten raw. Don't break yourself from the Party and the people just to show off!"

"Gaga! When you idiot are lying around for your livelihood, I have been learning and charging, knowing what you can eat and what you can't eat, and you don't have to worry about it."

Richard was full of confidence. He noticed the plant before dark and saw a golden mouse rushing away from the grass, holding a red-brown fruit in his mouth. Since the golden mouse can eat it, it may also eat it.

Zhang Zian was too lazy to care about it, but considering that if it got a stomachache or something and it would be too disgusting, it would be so disgusting, so he walked over curiously to see what it was eating.

After seeing the bush, he lifted Richard's feathers behind his head and pulled it up, "Don't eat it, you can't eat this."

"Ga?"

Richard was caught off guard and flapped his wings to break free, "Don't stop me, are you jealous, are you? I honestly admit that you are jealous, I will give you some to try!"

"You know what kind of plant this is, you can eat it? This is Oregon sorrel, a plant specialized in the mahogany forest. This plant can be eaten, and it can be eaten either with flowers, fruits, leaves or rhizomes. But that's for humans, for parrots... This plant contains too much oxalic acid. If you don't want to be paralyzed due to calcium deficiency, or have surgery due to kidney stones, it's best to spit out half of the fruit in your bird's mouth as soon as possible." He said.

"Ga?"

Richard was shocked when he heard this, and half of the fruit in his mouth fell back to the ground.

"That's right, parrots cannot eat foods that contain too much oxalic acid. You don't have a hint of it? Look at when did I feed you spinach?" Zhang Zian sighed helplessly.

"Plaguity...paralyzing?...stones? Isn't kidney stones the only disease you get? Because you don't use your kidneys for a long time, you get stones..." Richard was too shocked and said incoherently.

Whether humans or animals, the consequences of calcium deficiency are very serious. The oxalic acid in spinach will combine with calcium to form calcium oxalate, which will not only seriously reduce the absorption of calcium, but also deposit in the urinary tract system to form stones. The smaller the animal, the more troublesome it will cause, and the surgery will cause half of its life.

People do not eat spinach raw when eating it, but put it in boiling water and blanch it first, and dissolve the oxalic acid in water at high temperature. Even so, it can only remove most of the oxalic acid instead of all the oxalic acid. However, considering the nutritional value of spinach itself, it is still worth it.

For parrots, spinach and any vegetables with high oxalic acid content cannot be eaten, let alone eaten raw. It’s just that other vegetables are not as common as spinach, so spinach is often used as a typical example.
