4.6 Billion Year Symphony of Evolution

At the end of summer, it is a special time. During this time, the leaves will slowly fall, and the creatures start to store food and hide, as the surroundings become colder, waiting for the arrival of winter ...

But in fact, they did not do so.

Everything is different because of changes in the environment. A lot of wood decomposed by fungi and the huge nutrients accompanied by heavy rain and seawater infuse the twisted trees to grow crazy. They and the flooding rain charge in the direction of the desert. Long, twisted roots occupy this long desert.

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

At the same time in the direction of the mountain, because the black mud underground seems to have run out, so the twisted tree began to spread towards the barren area around the mountain. These crazy plants seem to want to occupy everything. The only thing that has not been attacked is 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 islands, home trees are also growing frantically, and these home trees also show Lin a wonderful thing, that is, there is no record of the Inca insect swarm, the origin of the underground world ...

After observing the whole summer, Lin finally understood these conditions.

The home tree hit the exploding seeds into the mud of the floating island. These seedlings grow very fast. They look green and tender, and they grow large fluffy leaves. Lynn found them caught with this leaf. The debris in the air feeds, it seems that the soil nutrients of the floating island are not enough, but Lin does not think there is any food in the high air, but they just grow this strange structure.

But Lin only began to think so, and later Lin discovered the meaning of these fluff.

The trunks of the home trees are quite straight, and they are not twisted like a twisted tree, but the direction of their growth is also very strange, and they are vertically down.

Yes, they do not grow above the empty island, but grow down at the bottom of the empty island, where the light is usually dark and there will be no direct sunlight, but they can also get some light energy, plus the root system Absorb, and because the floating island is moving slowly, they will drop a lot of debris every time they move. They rely on huge leaves to capture these debris from the floating island to increase nutrients.

Lin has been wondering why they are so long and complicated. Isn't it better to grow directly on them to absorb sunlight?It wasn't until Lin discovered the reason later that a large home tree had a strong wooden structure in its cortex, and it formed a downwardly tapered shape as a whole, and gathered a lot of sap at the tip of the end Increase the weight, and its bark has a heat-proof structure.

When there is a certain weight, usually more than one ton, these larger home trees will disconnect the root system, and at the same time will break down their leaves and fall from the floating island. These fallen cone-shaped trees will Directly inserted into the mud, sometimes it will fall into the sand, some hit the rocks and shattered, and Lin also saw a tree directly piercing a passing beetle.

Although this beetle feels pitiful, this tree is also dead. It can't do any more actions on the ground. Only the falling position is good, there are no shelters, and the soil is soft enough. The home tree can lean on it. The power of the sprint from a height of several hundred meters penetrated 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.

Home trees 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 split and a group of small creatures will appear inside.

These small creatures glow all the time, and Lynn finds that they are exactly the same as those glowing creatures at the top of the underground world.

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

Later, Lin discovered that the seeds of the home tree contained the eggs of these creatures.

Next, these home trees continue to grow underground, Lin only saw here, but they will obviously grow longer underground, opening up a huge space, and this group of light-emitting creatures are also attached to the top of this space constantly Breed and grow the community.

Lin did not find the symbiotic relationship between home trees and luminescent creatures in the underground world. Perhaps the luminescent creatures had reproduced a lot at that time, because they were all different species, and they could form an ecosystem themselves, and they did not need the home tree to provide energy. It's just that they are still glowing, maintaining the light of the entire underground world ...

Is this the origin of the underground world?

If a large number of home trees are fully grown, they can indeed prop up a new world.

This feeling is really wonderful, how have they evolved such a system?But it is true that all of the home trees need to rely on the "month" to achieve, only the month, they can fly to the sky and plunge underground.

However, Lin hasn't seen any home tree that can be so deep in the underground world. The reason why it may be so deep is related to the Inca insect swarm. Lin has seen their statues surrounding the small home tree.

But these home trees are still deep enough at present. Lin wants to research something special based on their structure, like a ground-burst bomb 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 large home trees, such as those in the canyon, have not found any problems at present, but may also die slowly This can also explain the cause of the death of the home tree on the ground.

Lin wanted to see how the trees propped up the earth, but another factor made it all pause.

……winter.

After the plants had grown wildly at the end of the summer, they had to stop because of the cold temperature. The snowstorm clouds gathered in the air, and the white debris flew in the air. This season of dormancy finally came. .

Moreover, this is the season when the Inca Swarm will leave.
