In fact, a long time ago, Song Zheng always had the idea of wanting to renovate the dungeon. Bayi Chinese?net? ? ≠＝≥．≠８≈１≤Ｚ≈≤．≠ＣＯＭ

But there has been no real action. It is really because the dungeon is more difficult to renovate, and the original materials are scarce, and the cost of transformation is huge, which is not something that the Jincheng base can afford.

After the Miracle Tree was upgraded, he was able to exchange a lot of functional plants from the Elf Shop, which gave him the idea of renovating the dungeon.

Human beings are very different from King Kong Titans, even if the dungeon is imitated from the human city, after all, all the metal materials, let people live in it directly, there are still many unsuitable places. Even after a long time, there are hidden dangers whether it will cause some bad effects.

The appearance of elven lichen is where Song Zheng's confidence lies in the real transformation of the dungeon.

Elven lichens sound like mosses and duckweeds from their names, but they are actually similar to normal lichens only superficially, but in fact there is a huge difference.

To put it simply, elven lichen is actually equivalent to a mixture of soil and turf.

As long as you spread a layer of elven lichen on the ground, then you can plant crops and grow trees on top of elven lichen, which is a very useful thing to transform the environment.

Even for elves who can fly around in spaceships, the role of elven lichens is irreplaceable. Because no matter what kind of harsh environment it is, as long as it is solid land, then after laying a layer of elf lichen, it will soon have an impact on the environment and be transformed.

The tiny plants on the elven lichen have excellent adaptability, whether in the desert or on saline-alkali land, they can quickly grow and survive, transform the soil and ground, and make the place covered by the lichen become able to grow plants, suitable for the elves to survive.

Because lichen is a very magical plant, their growth and existence not only rely on the nutrients in the soil, they are able to absorb all kinds of nutrients from the environment can survive, whether it is light, water or radiation, can become their nutrients after a short adaptation, so as to grow and take root quickly, and then can be transformed.

Although it is said that in the dungeon, all are metal, regardless of the ground or the sky, but there is light, energy, and air, and there is room for elven lichens to live.

"Be careful, be careful, don't break up the lichen!"

Song Zheng commanded the personnel to carry rolls of elven lichen to the dungeon.

They are quite similar to turf, and before they were paved, they were also very fragile, and there had already been cases where the elven lichen was accidentally broken, which made Song Zheng feel distressed.

The inhabitants of the dungeon have all been evacuated outside, and the work of laying elven lichen has to be carried out.

For the renovation of the dungeon, the residents are very enthusiastic, and many people stand outside the dungeon and do not leave, standing at the entrance of the passage to watch the excitement.

Song Zheng stood on the street of the dungeon, every fifty meters on the side of the road, there was a roll of elf lichen placed there, and when all the elf lichen was moved in, it would be opened together for laying.

"President, the elven lichen is all placed, can it be laid?" Zhou Pan panted and ran to Song Zheng's side to ask for instructions.

Song Zheng nodded, and used the communication beetle to directly give orders to the team leader in charge of each road section: "Start laying!"

With Song Zheng's order, one by one the elven lichen rolls were opened, laid on the side of the road, laid on the ground, and laid in a pre-set lot.

After the small lichen plants were laid, they immediately stretched out their curled leaves, trying to adapt to the environment of the dungeon, and the genes inside were changing, and the lichen was spreading and growing rapidly.

Exclamations of amazement rang out throughout the dungeon.

Elven lichens grew and spread rapidly, quickly connecting patches of lichens. And quickly thickened, the tiny plants absorbed a large amount of carbon dioxide, producing oxygen, which immediately made the air in the dungeon even fresher.

People take deep breaths and look at their faces with pleasure.

Compared to cold metal, human beings still prefer nature and green, and the dungeon seems to have become lively and vibrant because of those lichens.

Song Zheng walked onto the ground covered with elven lichen and stepped on it hard, feeling that his feet were not thin lawns, but thick earth, full of life and pregnant with hope.

"Can we plant a tree on it?" said the professor, eagerly stepping on the lichen under his feet.

Song Zheng smiled: "Of course not, let them grow for a while, and wait until the thickness reaches about ten centimeters, which can be considered as meeting the requirements." ”

Professor Wu's eyes flashed with the light of discovering the truth, and he squatted down and pulled out some lichens: "These little guys are really magical, they have to study and study hard." ”

Song Zheng couldn't cry or laugh, research is research, don't need to pull weeds from the ground in front of me, am I reluctant to exchange even a piece of lichen for the laboratory.

He was also afraid that there would be something bad about the lichen being pulled, so he hurriedly stopped Professor Wu and promised that he would definitely exchange some for laboratory research, so that the professor stopped destroying those small leaves.

"What should I do next?" Zhou Pan asked Song Zheng.

Song Zheng said: "First plant the street lamp flowers, as well as rattan chair plants, and get some public facilities for our city, and more things have to be planted after the ground coat grows up." ”

"Don't worry, President, I'll leave it to me next, I'm sure I'll do it properly. "Zhou Pan beckoned people to do things.

Song Zheng did not stay in the dungeon and chose to go home.

For the renovation of the dungeon, it is certainly not possible to complete it overnight, it is necessary to continuously add functional plants, and now that it has started, there are still many things to be done in the future.

Song Zheng handed over this task to Zhou Pan, and the little fat man was very positive about this matter itself, and it was certain that he would do his best.

After returning home, Song Zheng did not rest, and the committee sent some affairs that needed to be handled, and he continued to work by the side of the desk.

It took almost two hours before it was all processed.

Slightly tired, he sat down in his chair and closed his eyes.

Li Wanru walked in, got behind him, and reached out to help him massage his shoulders and temples.

"Isn't the work handed over to the committee, why do you have to work so hard?" she said with some concerned reproach in her tone.

"It's about functional plant layout planning, and they don't have any experience, so I also thought of where to write there, and I have to discuss and revise it later. Song Zheng said with his eyes closed.
