The rim of this hollow volcano forms a very sharp boundary with the rainforest.

The volcano is rocky and barren, but as soon as you step into the rainforest, the shade of the trees will cover the sky, and the dryness of the volcano will disappear immediately, replaced by humidity and muggy.

The rainforest here is so dense that it blocks more than 90 percent of the sun's rays, so even though it's still afternoon, the sun is still half the sky, but the jungle is already as dark as evening.

These trees vary in height, from as high as thirty or forty meters high, to seven or eight meters high, and are stacked on top of each other to form four or five layers of tent-like covers.

Thankfully, these tall trees shade the sun, so the vegetation on the ground is not dense and it doesn't seem too difficult to walk, but the damp and rotting leaves are thick on the ground, and you have to worry about the swamp that may appear at any time.

The humidity here is so great that the skin becomes sticky almost immediately as soon as you walk in, and there must be a lot of rainfall here, and the moisture evaporates in the heat, but most of it is suffocated by these dense canopies, creating a steamer-like climate.

Making a fire can be a bit tricky here, but with flint in your backpack and some effort, you should be able to do it.

Yun Yanuan looked at the trees in front of him, more than 90% of them did not know him, this is not surprising, the distribution of tree species in the tropical rainforest is the most even, but also the most dense.

No single plant dominates the area, but the trees all have a lot in common: the stems are smooth and straight, with few branches and foliage underneath, mostly concentrated in the canopy.

This is also the evolution of trees caused by the environment, after all, the plants here are very tall, and if you want to better receive sunlight and photosynthesis, then the leaves must be very high.

Yun Yanuan glanced at the rainforest in front of him, was silent for a moment and said: "It's too late today, let's not enter the rainforest, let's camp at the boundary of the volcano, I'll go find something to eat, and bring some dry firewood back by the way, don't move, just wait for me here." ”

No matter where the rainforest is, it represents abundance, but also represents danger, a few people first came here, they didn't know the situation inside, and the light inside was so dim, Yun Yanuan didn't want them to have any accidents.

The four women obediently waited for the man who entered the forest at the border, and by the way, they picked up some stones, made a simple stove with wind proof, put a steel helmet on it, and then laid the skin of the candle nine yin, and sat there.

They know that in such a climate and environment, there must be all kinds of possible dangers, Yun Ya Nuan needs to do a simple understanding, this time will not help with the past, but will distract Yun Ya Nuan's attention.

Therefore, waiting quietly is the best help.

The rainforest was dimly lit, and the canopy above the trees stingily blocked all the sun's rays, all the light came from the occasional small hole, and the sunlight drilled straight through the holes, giving a ray of light to the dark environment.

Yun Yanuan touched the red ground a few times with a branch, and found that the soil here was soft and wet, and it seemed that it was precisely because of such a humid and hot environment that the dead plants and fallen leaves were corrupted into mountain soil in the fastest time.

Red soil is a major feature of tropical rainforests, the soil in the rainforest is mostly red, drill red is generally in places with relatively little rainfall or better drainage, and the soil color here is gray red, which proves that the rainfall here is very large, and drainage is very difficult.

Both of these environments have their own advantages and disadvantages, but as far as Yunya Nuan is concerned, he would rather walk in the gray and damp red soil like this than walk in those red areas.

Because of the abundant rainfall and closed forests in the gray red soil, it is difficult for herbaceous plants to grow in such an environment, so it is much easier to walk.

If it is in a place with dense herbaceous plants, then Yun Yanuan should consider finding a river first, and then make plans, because they can't keep moving forward through thorns and thorns, which is a test of physical strength, and there are too many hidden dangers.

Yun Yanuan observed the terrain and walked downhill, looking for water in the tropical rainforest does not require a lot of experience and methods, you just need to look at the terrain and walk towards a low place, you will definitely encounter a water source.

It could be a quiet pond, a rushing stream, or even a cascading waterfall. The most perfect is of course the waterfall, because it proves that the water source is a long flowing water, which will be very clean, and the stream is secondary, because the seemingly rushing stream may only be the product of heavy rain.

The least desirable is of course the pond water, the smaller the more unsafe, there are so many species of plants here that there is no way to know which plant is safe, so stagnant water is the most dangerous water source.

However, this kind of pool water is the most common in the tropical rainforest, and Yun Ya Nuan walked not far before he came across such a pool with a diameter of only three or four meters.

The water looks very clear, and it just so happens that there is a hole in the canopy next to it, and the sunlight shines directly into the pool, so you can see the bottom all the time.

There were no insects, fish, and no underwater plants growing in it, and it was clear that it was just stagnant water after heavy rain, and Yun Yanuan was very dissatisfied with this water source, but he didn't have time to find a better water source.

Leaning down, he took a handful of water in his hand and sniffed it under his nose, there was no peculiar smell, he used the skin of a quick candle in his backpack, stuck both sides with his hands, formed the shape of a pot, scooped up a full water, and then turned around and rushed back to the camp.

The environment at the edge of the rainforest was quiet, and there were no traces of large animals, which made it safe for Yun Yanuan to let them look for firewood to light on the edge.

The water that came back was poured directly into the steel helmet, Diana and Seami went to look for firewood, Kexin and Maya were guarding the place, and Yun Yanuan's task now was to find something to satisfy his hunger.

They have no food left, and if they don't find anything to eat, they may starve for the first time since they entered the island. This is something that Yun Yanuan will never allow, especially since tomorrow they are about to start a new journey, and he can't let a few women go hungry.

In the rainforest, you can be bitten by mosquitoes and poisonous snakes, eaten by huge and sinister beasts, and even plants with strange thorns can kill you. However, there will be absolutely no starvation.

Because in such an environment, both animals and plants are too rich, although more than 90% of the plants here are not recognized by Yunya Nuan, but just by knowing 10%, it is enough for them not to starve.

He had only gone a few hundred meters into the jungle when he saw the treasure that made him ecstatic, a banana tree about five or six meters high appeared in front of his eyes.

The fruit on it is green with golden yellow, and it is obviously about to be fully ripe, but the taste is not bad now, and several people have eaten wild vegetables and meat for many days, and now it is the first time to see fruit on the island.

Bananas are very nutritious, they can quickly replenish energy, and banana trees can also be eaten after peeling them, but since there are bananas, Yun Yanuan is too lazy to cut down the tree poles to go back to satisfy his hunger.

He strode towards the banana tree, when suddenly a dangerous wave of qi attacked his cranial nerves......
