Chapter 1513: Sorrel

Humans are social animals, and the more people there are, the more secure they feel. Zhang Zian had camped in the desert before, but at that time he had a large group of people, excellent equipment, and powerful vehicles, but now he is alone, and his equipment is only the average level of a camper in the wild. The important thing is - 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, you can ignore it, but in the virgin forest...

In the evening, the fog became thicker, and it was difficult to ignite the wet dead branches. Zhang Zian had to use solid alcohol to support the combustion, so that he could light the fire.

Afterwards, it was still boiling water for cooking. If there was any difference from noon, the taste of the canned food was changed, and a pot of weak tea was boiled to warm the body.

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

"Squeak..."

Zhang Zian heard that π's cry was different, and saw that its two fists were still clenched. He walked over and opened its hands, and saw that its palms had been blistered.

π had a great time playing on the tree today, and even got carried away. It forgot that its hands are more adapted to the touch of the keyboard than the roughness of the bark, and ignored the fact that it is actually a house monkey. Its palms are not as good as those of other monkeys. The calluses that have been worn out, I didn't realize that something was wrong until the palm was hot and burning, but I didn't dare to tell everyone because it was my fault.

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

He popped the blisters on it, sterilized it, applied medicine, and finally wrapped it in a bandage. The dressing technique was very poor. After all, he was not a professional nurse, as long as it was practical. But tomorrow Pi sure can't be dangling from a tree branch, or walking honestly - which is not something monkeys with long arms and short legs are good at, or getting back into the phone.

The other elves were also very tired after a day of hiking, and even missed the days of riding in a car in the desert-the memory will always beautify the past, selectively forgetting the fact that the temperature inside the car in the desert is no less than that of a steamer.

"Give me nuts again? What about fresh vegetables? Fresh fruits? Are you an idiot trying to make my uncle malnourished?" Richard fiddled with his bird's claws on the stainless steel plate, which contained some Mixed nuts.

"There are freeze-dried fruits, but I didn't bring much, you have to save them." Zhang Zian opened a small bag of freeze-dried fruits and put them on his plate, including blueberries, strawberries, mangoes, pineapples, etc. Although freeze-dried fruits are very Lightweight, but it takes up too much space to carry a lot.

Normally, Richard would at most complain about a few words of integrity and then bury his head in eating.

But it felt that it lost its face during the day, and wanted to get back to the place, so it dismissed the freeze-dried fruits aside, and shouted: "Don't use these freeze-dried ones to fool me! Fruits must be fresh to taste!"

Zhang Zian didn't know what it was doing, "If you don't eat it, you will fall down, and if you don't eat it, I will eat it."

When Richard saw him put freeze-dried strawberries and mangoes into his mouth, he was anxious, but there was always a price to pay to get back the place, so it flapped its wings and flew to a nearby herb with beautiful heart-shaped leaves, Probe pecked at the fruit of the plant, and shouted with relish: "Quack! It's sweet and delicious!"

"Have you seen Master Pei's Survival in the Wilderness? In the wilderness, the most authentic way of survival is to use local materials. I look down on someone like you who enters the wilderness with big bags!" it smugly called.

Most of the other elves are carnivores and have no interest in fruits, so its clamor did not arouse everyone's envy and hatred, so it made more noise.

Zhang Zian kindly reminded: "There are few edible plants in the forest, let alone raw ones, so don't cut yourself off from the party and the people just to pretend to be coercive!"

"Quack! When you, an idiot, was running around for a living, my uncle has been studying and recharging. He knows what can be eaten and what can't be eaten, so you don't need to worry about it."

Richard was so confident that he noticed the plant before it got dark, and saw a chipmunk fleeing from the grass in a hurry, with a reddish-brown fruit in its mouth—since chipmunks can eat, then It's probably edible too.

Zhang Zian didn't bother to take care of it at first, but considering that it would be too disgusting if it ate something bad, it would be too disgusting, so he walked over curiously to see what it was eating.

After he saw the clump of plants clearly, he grabbed the feathers on the back of Richard's head and picked it up, "Don't eat it, you can't eat this thing."

"Gah?"

Richard was caught off guard, flapping his wings and trying to break free, "Don't stop me, are you jealous? Honestly admit that you are jealous, and I will share some with you!"

"You know what this plant is and you eat it? This is Oregon wood sorrel, a plant that is native to redwood forests. This plant is indeed edible, and it can be eaten whether it is flowers, fruits, leaves or roots, but That’s for humans, but for parrots... This plant contains too much oxalic acid. If you don’t want to suffer from fractures and paralysis due to calcium deficiency, or surgery due to kidney stones, you’d better have your bird Spit out the half fruit in your mouth," he said.

"Gah?"

Richard was startled when he heard this, and the half fruit left in his mouth slapped back to the ground.

"That's right, parrots can't eat food that contains too much oxalic acid. You don't have a clue? When do you think I fed you spinach?" Zhang Zian sighed helplessly.

"Paralyzed... paralyzed? Kidney stones? Isn't kidney stones a disease that only you get? You get stones because you don't use your kidneys for a long time..." Richard was too shocked and said incoherently.

Regardless of humans or animals, the consequences of calcium deficiency are very serious, and 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 calcium oxalate itself in the urinary system, forming stones. The smaller the animal, the more troublesome it is to get stones, and the operation will kill half the life.

When people eat spinach, they will not eat it raw, but put it in boiling water first, and use high temperature to dissolve the oxalic acid in the water. The nutritional value is worth it.

For parrots, spinach and any vegetables with high oxalic acid content cannot be eaten, let alone raw, but other vegetables are not as common as spinach, so spinach is often taken as a typical example.
