Chapter 155: Underground Origin

The end of summer is a special time when the leaves slowly fall and the creatures start to store food and hide, waiting for winter to come as it gets colder around...

But in reality, they didn't.

Because of the changes in the environment, everything has changed. Many woods decomposed by fungi in the ground, and the huge amount of nutrients accompanying the influx of heavy rain and sea water make the twisted trees grow wildly. Long, twisted roots dominate this long-dried desert.

In just a few dozen days, the twisted tree can grow a tree nearly ten meters high from the root system with a lot of nutrients. They spread towards the desert at this speed. The twisted tree and the rain turn the gravel into mud, and there are many Creatures also followed the spread of the twisted trees and slowly began to live in the desert.

At the same time, in the direction of the mountain, because the underground black mud seems to have flowed out, the twisted trees began to spread towards the barren area around the mountain. These crazy plants seem to want to occupy everything. The only ones that have not been attacked are those in the underground world. In the canyon, the twisted tree seems to be unable to directly absorb the seawater, but whenever the rainstorm floods the water in the canyon, the twisted tree can absorb the nutrients in the seawater through the seawater desalinated by the rainstorm.

At the same time, on the floating island, the home tree is also growing frantically, and these home trees also show Lin a wonderful thing, that is, the origin of the underground world, which is not even recorded by the Inca swarm...

After observing all summer, Lynn finally understood the situation.

The home tree smashed the exploding seeds into the soil of the floating island, and these seedlings grew rapidly. They look green and tender. And grow large leaves with downy. Lin found that they used this kind of leaves to capture the debris in the air for food. It seemed that the soil nutrients in the floating island were not enough, but Lin didn't think there was any food in the air at such a high altitude, but they just grew like this. kind of weird structure.

But Lin only began to think so, and only later did Lin discover the meaning of the fluff.

The trunks of the home trees are quite straight, not curved like a twisted tree at all, but they also grow in a strange direction, straight down.

That's right. They do not grow on the top of the empty island, but grow down at the bottom of the empty island, where the light is usually dark and there is no direct sunlight, but they can also get some light energy, plus the absorption of the root system, and Because the floating islands are moving slowly, they will drop a lot of debris every time they move. They rely on huge leaves to capture the debris dropped by the floating islands to increase nutrients.

Lin has always wondered why they grow so complicated, isn't it better to grow directly on it to absorb sunlight? It wasn't until Lynn later found out why. There is a solid wood structure in the cortex of a larger home tree,

And it forms a downward pointed cone-like shape as a whole. And gather a lot of sap at the tip of the end to add weight, and its bark has a heat-resistant structure.

When there is a certain weight, usually more than one ton, these larger home trees will break off their roots, and at the same time will decompose their own leaves and fall from the floating island. It plunged directly into the mud, sometimes it fell into the sand, and some hit the rocks and became shattered. Lin also saw a tree pierce a passing beetle directly.

Although this beetle feels pitiful, the tree is also dead. It can no longer do any movement on the ground. Only when it falls in a good position, there is no obstruction, and the soil is soft enough, the home tree can lean on it. The power of sprinting from a few hundred meters high into the ground to a depth of tens of meters or even hundreds of meters, after stabilization, the life of this home tree has just begun.

The home tree will grow roots at both ends and insert into the mud to absorb various nutrients and grow small leaves. At the same time, their bark will crack, and a group of small creatures will appear inside.

These small creatures all glowed, and Lin found that they were exactly the same as the glowing creatures on the top of the cave in the underground world.

It seems that the home tree has reached a symbiotic relationship with them. They will live and reproduce around the home tree. The home tree will absorb some nutrients in the mud to provide these creatures. These creatures also provide light energy to the home tree, and these creatures themselves will also Go to the mud to find food.

Lin later discovered that the seeds of the home tree itself contained the eggs of these creatures.

Next, these home trees continue to grow underground. Lin only sees it so far, but they will obviously grow bigger and bigger underground, opening up a huge space, and these luminous creatures are also attached to the top of this space. Breed and grow the colony.

Lin did not discover the symbiotic relationship between the home tree and the luminous creatures in the underground world. Maybe the luminous creatures had reproduced a lot at that time, because they were all different species, and they could form an ecosystem of their own, and they did not need the home tree to provide energy. It's just that they are still shining, maintaining the light of the entire underground world...

Is this the origin of the underworld?

Plenty of home trees can indeed hold up a new world if they are fully grown.

This feeling is really wonderful, how did they evolve such a system? But it is true that all of the home tree needs to rely on the 'moon' to achieve, and only the moon can they fly high into the sky and plunge into the ground.

However, Lin has not seen any home tree that can penetrate so deep into the underground world. It may be related to the Inca swarm. Lin has seen the statues of them surrounding the small home tree.

But these home trees are still deep enough, and Lin wants to research something special based on their structure, such as burrowing bombs or something.

In addition, Lin also found that the home tree seems to be afraid of direct sunlight. If the small home tree is exposed to direct sunlight, it will die soon, while the big home tree, such as the ones in the canyon, although no problems have been found so far, may also die slowly. , which can also explain the cause of the death of the home tree on the ground.

Lin wanted to see how the trees held up the ground, but another factor put it all on hold.

……winter.

After the last crazy growth of the plants at the end of the summer, they had to stop because of the cold temperature. The clouds of the blizzard gathered in the air, and the white debris flew in the air. This season of dormancy has finally come. .

Also, this is the season when the Inca swarms will be leaving. (To be continued...)
