It was an arboretum that could only be found in the tropics, and the leaves of numerous trees were growing along the walls.

�The ecological environment underground.�No, more than that, how did you hold on until now?�

This was impossible without constant temperature, humidity and light.

�Let�s just go down.�I guess here����.�

I was reluctant to check the 4th floor with Yo.

�There is a bigger tree over there.�

But she was now stepping out first.

Entering the large arboretum sealed with glass walls, numerous computer devices were running, and a huge tree stood in the center.

Sirone, who came in belatedly, could guess Yo�s expression just by looking at Yo�s back.

�Uh huh?�

Standing in front of Yo�s eyes was smaller than what he saw from the outside, but it was definitely the tree of life.

Embryos with taps were clinging to the branches, and the wide glass tubes that contained the roots were filled with mucus from the mucus.

�How can this����we are����.�

As I was muttering yoga, the slime in the glass container rose all the way up and grabbed the fetus and pulled it.

Seeing the faucet snap and fall into the mucus, Yoro screamed with a pale face.

�Kyaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaah!�

�calm down!�If you make a loud noise����!�

Yo wasn�t crazy.

�Arson!�How did this happen!�Why is the tree of life here?�That said, the sun����!�

There was no way to know that it was Sirone, but there was a way to confirm it.

When I pressed the option button on the control device, the hologram turned on again and the explanation continued.

�Human Extinction Prevention Project.�Government Unofficial Approval.�also����.�

Like the Dynamic Humans, the Children of the Sun were not naturally evolved humans.

The contents of the document were telling us more shocking facts than what we saw on the first floor.

With more than 70 percent of plants and animals extinct and resources depleted, humanity has finally realized.

That humans should no longer be involved in energy.

Human greed ruined everything!

Humanity needed a special manager who was not swayed by desire, and the local energy circulation system Mucus was born as a result.

The significance of Mucus is to digest animals and plants with mucus to generate energy necessary for the ecosystem.

Eventually, however, as even the local energy dried up, it began to destroy and expand the limits of its territory on its own. JrNovels.com
