"The surrounding animals are very annoying to those excrements, and they never come here, so these trees that grow on the cave are very safe, and there is never a need to worry about animals destroying the growth of these trees, and there are no natural predators, so over time, these trees grow more and more densely, and its root system is supplied to those insects as food, and it will not destroy its growth at all" As if knowing Anxin's doubts, Yao popularized the knowledge here to Anxin and helped her solve her doubts.

"So, these trees provide the root system for these bugs to eat, and those bugs are protecting these trees in another way"? Anxin has to admire the magic of nature, even these inanimate trees, they know to sacrifice a little "pay protection money" to make themselves better survive.

"So these insects and trees are a symbiotic relationship" to find that these plants are often accompanied by some plants or animals living or guarding on the side, and their relationship is also commonly known as "symbiosis". For example, honey fruits and bees have this relationship, and now even trees and insects are the same.

"Well, that's pretty much it" was said by Anxin, isn't it a symbiotic relationship? A plant or creature is often more difficult to survive, so at this time, a "collaborator" is brought in to jointly resist the influence of the outside world, so as to get the most powerful protection.

"Let's hurry up and get some excrement to try the effect" sighed for a long time, and then remembered that the business had not been done yet, so quickly let Yao get some excrement to do the experiment.

"Okay" It didn't take long for Yao to get a bucket of milky white liquid.

Looking at the milky white liquid in the bucket, it was really hard to believe that this was actually the disgusting excrement of the bugs. On the outside, it looks very similar to milk, and it doesn't smell disgusting.

Until now, seeing that this excrement is not as disgusting and unacceptable as I imagined, Anxin has always been a little resistant, and then slowly relaxed.

Now that everything is complete, let's start to get it, sand and stones, in such a primitive place, just take it and push it a lot.

Prepare the things, use thin stone chips, stir some sand and excrement together, and then use the stones to make a wall almost more than a meter high.

Because Anxin and Yao worked together, it was quickly done, and the excrement was liquid, so it was not so easy to dry during this time, and Anxin and Yao only waited for it to dry naturally, so they could know what its effect was? Can it reach the degree of cement firmness.

"Yao, can we go up and have a look? Is there a way to this mountain" The waiting time will take a while, and now I can't do anything, so I can only wait quietly for the time to pass, but this time is quite long, and peace of mind is really boring. I came up with the idea of going to the cave.

She was actually interested in the trees in the cave. She had a faint feeling in her heart that this tree should not be an ordinary tree, after all, it can make this insect produce such sticky excrement, and the tree that provides the root system should also have other uses.

"I'll see, there should be" Yao looked for a while, and saw a road that could lead to the mountain, in fact, this can't be considered a road, it's just not so steep, just enough for people to walk through.

It's just that this "road" should have never been walked, and there are some weeds and wildflowers everywhere on the road, which is very difficult to walk.

Finally, when Anxin was tired and panting, he reached the top of the mountain, and Anxin found that the trees that were already very spectacular at the bottom of the mountain looked even thicker and taller on this, and it was not too much to describe it as almost covering the sky and the sun, because as soon as he came up, Anxin felt that the sun on his head did not shine in at all, making the surrounding environment black and pressing, and it felt very shady.

"Huh, what is this"? Just as I was looking around, I noticed that some of these trees actually began to leak out transparent liquid.

Out of curiosity, Anxin dipped some of his fingers and put them in front of his eyes to watch them up close.

This is a colorless and odorless liquid, and as soon as this liquid is touched on the hand, it doesn't feel like water, but a bit like glue, because it feels sticky, feel at ease with a gentle rub of your hand, the original transparent liquid directly becomes a rubber rope, or a very elastic kind, Q bomb Q bomb.

Looking at this scene, Anxin didn't understand anything, but I just felt that I was so lucky, but I didn't expect that I was just looking for a thing, and I could get another kind of "included" thing, and this thing is still very good, very rare.

I gently scratched the tree with my hand, and the trunk that was still dry began to flow "water" and tick down.

This rubber tree is called a tree that sheds "tears", and it really looks like it is shedding tears.
