4.6 Billion Year Symphony of Evolution

At the end of the summer, it is a special time. During this time, the leaves will slowly fall, and the creatures will start to store food and hide. As the surroundings get cold, wait for the winter...

But actually, they didn't do it.

Because the changes in the environment have caused everything to become different, many woods that have been broken down by fungi, and the huge amount of nutrients that accompany the torrential rain and the influx of seawater, have caused the twisted trees to grow wildly. They are charging the desert with the flooding rain. The long, twisted roots occupy this long dry desert.

In just a few dozen days, the twisted tree can grow a tree of nearly ten meters high from the roots by a large amount of nutrients. They spread at the speed toward the desert, twisting trees and rain to turn the gravel into mud, and there are many The creatures followed the spread of the twisted tree 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, the twisted tree began to spread towards the ridiculous 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. Canyons, twisted trees do not seem to directly absorb the appearance of seawater, but whenever heavy rains flood the canyon, the twisted trees can absorb the nutrients in the seawater through the seawater that has been diluted by the storm.

At the same time, on the floating islands, the home trees are also growing wildly, and these home trees also show a wonderful thing for Lin, that is, even the Inca insects are not recorded, the origin of the underground world...

After experiencing the entire summer observation, Lin finally understood these situations.

The home tree drives the seeds of the explosion into the mud of the floating island, and these seedlings grow very fast. They look green and tender. And grow large leaves with fluff. Lin found that they used this leaf to catch the debris in the air. It seems that because the soil nutrients in the floating island are not enough, Lin does not think that there is any food in the air in the air, but they are longer. A strange structure.

But Lin just started to think so, and later Lin discovered the meaning of these fluff.

The trunks of the home trees are quite straight, without the curvature of twisting the trees, but they are also very strange in the long direction, which is vertically downward.

That's right. They don't grow above 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 also get some light energy, plus the absorption of the roots, and Because the floating islands move slowly, each time they move, they will drop a lot of debris. They rely on the huge leaves to capture the debris dropped from the floating island to increase the nutrients.

Lynn has always wondered why they are so long and complicated. Is it better to absorb sunlight directly? It was not until Lin later discovered the reason. There is a strong wooden structure in the cortex of a larger home tree, and it forms a downward-shaped cone-like shape. And a large amount of sap is gathered at the tip of the tip to increase the weight, and the bark has a heat-proof structure.

When there is a certain weight, usually more than one ton, these larger home trees will break the roots, and at the same time will break down their leaves and fall from the floating islands. These falling cone-shaped trees will Directly inserted into the mud, sometimes falling into the sand, some hit the rock and become crushed, and Lin also saw a tree directly piercing a passing beetle.

Although the beetle feels pitiful, but the tree is dead, it can't do any more work on the ground. Only when the position is good, there is no obstruction, and the soil is soft enough, the home tree can lean against it. From the sprinting force of several hundred meters, it plunged into the depth of tens of meters or even hundreds of meters. After the stability, 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, and their bark will split, and a group of small creatures will appear inside.

These small creatures will shine, and Lin finds that they are exactly the same as those of the underground world.

It seems that the home trees have reached a symbiotic relationship with them. They will live around the trees at home. The home trees will absorb some nutrients from the mud to provide these creatures. These creatures also provide light energy to the trees, and the 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 are growing in the ground. Lin just sees it here, but they obviously grow bigger and bigger in the ground, opening up a huge space, and this group of glowing creatures are attached to the top of this space. Breeding and growing communities.

Lin did not find the symbiotic relationship between the home tree and the luminescent creature in the underground world. Maybe the luminescent creatures had multiplied at that time, because they are all different kinds, they can become an ecosystem, and they don’t need the trees to provide energy. But they are still shining, maintaining the light of the entire underground world...

Is this the origin of the underground world?

If a large number of home trees grow up completely, they can indeed hold up a new world.

This feeling is really amazing. How did they evolve such a system? However, it is true that all of the home trees need to rely on ‘month’ to reach, and only months, they can fly to the sky and into the ground.

However, Lin has not seen any home trees that can be so deep in the underground world. The reason why it may be so deep is related to the Inca insects. Lin has seen the statues surrounding them in small home trees.

But these home trees are now too deep, and Lin wants to study something special based on their structure, like a ground bomb.

In addition, Lin also found that the home tree seems to be afraid of direct sunlight. If the small home tree is directly exposed to the sun, it will soon die. The big home trees, such as those in the canyon, may not be found, but they may die slowly. This will also explain the cause of the death of the home tree on the ground.

Lynn wants to see how these trees hold up the earth, but another factor has caused it to pause.

……winter.

After the last crazy growth of the plants at the end of the summer, the plants had to stop because of the cold temperatures. The clouds of the blizzard gathered in the air, and the white ends of the clouds flew in the air. This season of sleep is finally coming. .

Moreover, this is also the season when the Inca group is about to leave. (To be continued, please search for astronomical literature, the novel is better updated faster!
