Wilderness: After the college entrance examination, I got the strongest survival system

There were many birds in the woods, but Li Yingjie had never thought of laying eggs before.

The main reason is that most of the eggs are too small.

A nest of birds' eggs may not be enough for them to eat alone.

Of course, there are also big eggs, but it is not easy to climb up the tree and pick the nests one by one to see if the eggs are big or not.

And the most important thing is that Li Yingjie and the others haven't been short of food. If they didn't use bird eggs to test the alkalinity of the lime water this time, they wouldn't have come to climb trees to look for it.

Considering that someone might go to the cabin to cause damage, Li Yingjie didn't leave too far away.

There are many bird nests in the nearby trees. After walking tens of meters across the stream, he saw seven or eight bird nests.

However, most of the bird's nests are relatively high, and Li Yingjie felt that it was not easy to climb up, so he kept looking ahead.

Finally, I saw a slightly lower bird's nest.

Moreover, the thickness of the trunk is just right, making it easy to climb up.

Li Yingjie put his things down, without using anything, hugged the tree trunk with both hands and legs, and climbed up.

In fact, climbing trees is also very energy-consuming, and it also requires strong enough strength in the arms, legs and waist.

However, this is not a big problem for Li Yingjie.

The only problem was... when he climbed the tree, he found that there were no eggs in the nest.

Moreover, from above, this bird's nest should not have been inhabited by birds for a long time.

It was empty and dilapidated inside.

"Unlucky!" Li Yingjie said secretly, and slid down the tree trunk.

He suddenly felt sorry for his clothes.

Climbing trees is a waste of clothes, so try not to climb trees in the future.

Otherwise, if my clothes are rotten, I can't snatch Lin Xiaoying's clothes to wear!

He walked forward for tens of meters and found a bird's nest again, but after climbing up, there were still no eggs.

After I got down, I searched for a while, and after I found a bird's nest again, I climbed up to have a look, but it was still not there.

"Life is called life if it is not smooth enough!" Li Yingjie ripped his clothes with some regret.

If you climb again, you must be more careful.

Li Yingjie even wanted to take off his clothes and pants, lest they be too worn out.

Of course, this is just a thought.

After searching seven or eight bird's nests in a row, Li Yingjie finally found a bird's egg in the last bird's nest.

These are all the same size as quail eggs, and there are eight or nine in a nest.

Li Yingjie felt that eating all of these eight or nine was not enough for his breakfast.

He didn't take all of them, but took three out of them and put them in the pocket of his jacket.

Then, carefully descending the tree, he hurried back to the cabin.

Lin Xiaoying was sitting in the room making brick embryos, when she saw Li Yingjie came back, she immediately opened the door for him.

"It's so fast, I thought it would take a long time!" Lin Xiaoying said.

"Of course, you don't even think about my speed!" Li Yingjie said proudly.

This was a normal sentence, but in Li Yingjie's live broadcast room, it suddenly became a fast train.

Wu is not bored: "Hey! What is this speed, is it the speed of the day or the speed of the night!"

Keep scrolling: "Upstairs, the anchor is communicating normally, don't stain him with your thoughts."

Annoying or not: "Annoying or not, watching a live broadcast of survival in the wild can keep driving!"

Others expressed their curiosity.

A small stick: "By the way, what is the host going to do with the bird's eggs? He said to measure the alkalinity of lime water. Can bird's eggs be used to measure its alkalinity?"

Learning in general: "Under normal circumstances, when measuring the specific gravity of poultry eggs, alkaline water is used. If the egg is relatively fresh and the specific gravity is normal, it will be suspended in the middle of the alkaline water, neither sinking nor floating, but I don’t study well, so I don’t know if this is the principle!”

The weak one: "Good guy, learn from the average academic master, there are still hidden knowledge points here."

The creature is in a hurry: "Write it down, next time you buy eggs, just test it like this!"

On the deserted island, after Li Yingjie returned to the cabin with the bird's egg, he put it in the ashes water.

"Can we see the strength of alkalinity?" Lin Xiaoying asked curiously.

Her chemistry knowledge is average, but, after all, she also went to university, so she still knows a little bit.

Generally, pH test paper is used to measure the strength of alkalinity, and it is judged by the depth of the color of the test paper.

Of course, there is a pH meter for more professional equipment, which can use bird eggs to measure the strength of alkalinity, which I have never heard of.

Li Yingjie smiled and explained: "This is the knowledge of the specific gravity of poultry eggs, but I only know the superficiality, and the real principle is not very clear."

He explained: "Whether birds' eggs are placed in plant ash water, whether they float up or sink to the bottom, it means that the alkalinity of the plant ash water is not up to standard!"

Li Yingjie gently put the bird's egg in, and the two immediately saw that the bird's egg was suspended in the middle of the water.

"Look, that's it!"

With that said, Li Yingjie carefully picked up the bamboo tube containing the plant ash water, poured the settled water into the clay pot next to it, and poured out the remaining plant ash at the bottom.

Li Yingjie checked the precipitated water carefully again, and after confirming that there were no impurities in it, he said to Lin Xiaoying:

"Now you can start the next step!"

Lin Xiaoying watched curiously.

I saw that Li Yingjie dug out a piece of bear oil with a bamboo slice, poured it into a clay pot, and then began to stir continuously with the bamboo slice.

In the clay pot, the clarified plant ash water and bear meat are constantly mixed together, separated from each other at first, and then gradually mixed.

The contents inside also became viscous.

"Just keep stirring like this. If it's winter, you may need to heat it up, but now the temperature is relatively high, and the bear oil hasn't solidified, so the heating step is omitted." Li Yingjie stirred while explained.

After stirring for a long time, the liquid in the clay pot became more and more viscous.

At the beginning, water was mixed with oil, and then it gradually became a solid like mud, and the ash water and lard were completely fused together.

Li Yingjie brought over a pottery cup that Lin Xiaoying made last time, poured these solidified things into it, and filled the cup full.

"Is this all right? It's still fluid now?" Lin Xiaoying asked curiously.

Although it is no longer a liquid like water, it has not solidified and does not look like soap at all.

She took the cup and smelled it, but she didn't smell anything.

Li Yingjie said with a smile: "It hasn't completely solidified yet, and it needs to be placed for two or three days. Moreover, there is no other thing added in it, so naturally it has no fragrance."

Lin Xiaoying nodded and said excitedly:

"Then next time, we can find some flower petals and add them in, so that we can make a flower-scented soap."

"Of course you can!"

Li Yingjie agreed, and put the cup of soap in a cool corner, waiting for it to solidify.
