"Meng Yang, the five groups of Sky Survey Eagles and Explorers have all completed their tasks, and they ask for instructions on the next mission. Pen, fun, pavilion www. biquge。 info," he said.

"Hmm...... Let them check the underground of the Great Yuan Empire when they have time to see if there are any other large spaces. ”

"Good!"

Leaving things to Xiao Budian to arrange, Meng Yang concentrated on studying these underground spaces.

Material delivery is a big problem!

To build an ecosystem with a volume of tens of cubic kilometers, the organic matter required is at least hundreds of thousands of tons, and such a huge amount of material transportation may not be able to be done in a moment and a half.

Meng Yang thought about it and decided to design a special creature to take care of this.

It took more than a week for Meng Yang to come up with a design draft, and the new creature was the size of a rugby ball, like a very large almond.

"Don't be careful, bring a Sky Survey Eagle back and bring this ...... Let's call it the base tree...... Delivered to Q3 space. ”

Space Q3 is a group of karst caves just over 50 meters above the surface, which is composed of dozens of large karst caves that are interconnected, as if a large string of sweet potatoes has grown underground.

This group of karst caves has good water resources, and most of the caves have underground rivers passing through them, and some karst cave creatures live in the underground rivers.

After a short time, a Sky Survey Eagle landed in the courtyard, Meng Yang threw the Base Tree Seed to it, and by the next day, the Sky Survey Eagle had already brought the Base Tree Seed to the sky over Q3.

"Plant the base tree seeds near the entrance."

The Sky Survey Eagle landed at the entrance where the explorers had entered the ground, carved a large hole with its claws, and threw the base tree seeds the size of a rugby ball into it.

Before the floating soil is covered, the base tree seed is activated.

I saw that a few tentacles suddenly grew on the surface of the rugby ball, and these tentacles were like earthworms, actively digging into the soil and beginning to absorb the water in the soil frantically.

Other tentacles seemed to be able to climb on their own, snaking their way to the ground, and soon climbed a nearby tree, which pierced into the bark of the tree and into the trunk.

Almost visible to the naked eye, the tentacles began to grow thicker and thicker, the thickness of a water pipe, and something was constantly flowing inside it, and the liquid was transported back to the seeds, causing them to expand and grow rapidly.

With the replenishment of matter, one tentacle is born, more tentacles dig into the soil, strive to burrow deeper into the soil, more tentacles extend out, penetrate into the surrounding shrubs, penetrate into the surrounding trees, and more and more life matter is transported back.

The base tree began to sprout, a leaf bud broke out of the cocoon, growing rapidly, this leaf bud seemed to fast forward, constantly getting bigger, growing taller, only ten minutes later, a very ordinary tree appeared in the same place.

The root system of large trees is becoming more and more developed, and more and more roots extend from the soil in all directions.

When a certain root system encounters a large tree, it immediately burrows into it, encroaches on and transforms the tree, and it does not take long for the tree to be transformed, and with it as the center, many root systems also spread.

The root system of the base tree seems to be contagious, constantly occupying one plant after another, and after they are completed, they use these plants as a starting point to release more roots to occupy more distant positions.

As if fission, a tendrils took over a plant, and in just a few minutes, several new roots sprouted from the root system of the plant, which spread through the soil, seeking and occupying new plants.

Silently, the network of roots of the base tree spread out beneath the surface, like a large net, and it continued to grow radially in all directions, and all the plants in its path were incorporated into its body, and all plants were fused and transformed by it.

Soon, the roots of the base tree reach a mountain stream, and each root sinks into the water, turning into a powerful suction pipe, and the filtered water is pumped back to the entire root network, where it is quickly delivered to every plant in the network.

Nourished by sufficient water, the leaves of these plants become wider and thicker, and the stomata on the leaves open one after another, quickly absorbing carbon dioxide in the air, which under the action of sunlight, becomes a carbon chain and becomes the organic matter that makes up life.

This newly generated organic matter is transported through various channels to the edge of the root network, where it becomes new roots, expanding the range of the root network, occupying new plants, and incorporating more plants into the network.

This process is constantly circulating, with more and more plants controlled by the base tree, more and more photosynthetic capabilities, and more and more organic matter being statistically dispatched and distributed.

In just a few days, the base tree had completely taken control of all the plants on the mountain, and beneath the surface, the root network was in all directions.

Just like the highways at all levels, these root systems vary in thickness, the thickest root systems are the highways, they are responsible for the main water and nutrient transport functions, they are buried deepest, with the base tree as the center, extending radially.

Throughout the highway, national and provincial highways are constantly divided, and these slightly smaller root systems are responsible for the distribution and convergence of materials at the next level.

Provincial roads, county roads, village roads, and field roads are divided into levels to form a material transportation network covering the entire mountain.

The plants on both sides of the stream dig their roots into the water, and the filtered roots quickly absorb the water, and the water is sent to every plant scattered over the mountain, and through photosynthesis, it becomes various organic matter, which is sent to the base tree again for storage.

"Ask Base Tree One, how many tons of organic matter can it produce per day now?"

"Base Tree No. 1 said that the current area of controlled plants is 1.5 square kilometers, which can produce about 100 tons of organic matter a day."

One hundred tons ......

At this rate, it is estimated that it will take decades to build a new ecosystem with these organic matter.

"Let Base No. 1 continue to expand and take down several surrounding hills."

After receiving Meng Yang's order, thick roots spread out in all directions, and in the depths of the mountains, without anyone knowing, a huge root network covering dozens of square kilometers around was slowly taking shape.

Several surrounding mountains were incorporated, and several streams in the mountains became water draws, and the streams were filled with the roots of plants on both banks, and the water level of the streams dropped out of thin air, and a large amount of water was quickly sent to the surrounding plants.

In just a few weeks, Base Tree No. 1 has built an extremely large network of plants, covering an area of more than 100 square kilometers, including multiple villages, spanning several mountain roads, and covering many rivers.

This is probably the largest creature ever built on Earth!
