Although his sister's cooking was good, Xu Wu, who was full of worries, returned to his room again after eating a simple hello, and he had to think about how to refuse marriage and how to clear customs, and he was distressed.

It's just that Xu Yao couldn't help frowning when he looked at Xu Wu and fled back to the room like a mouse.

"My brother seems to be getting sicker, no, I can't let him stay at home, I have to find a way. Ask him to buy something for me. It doesn't seem like there are enough drinks, and there's not enough for supper, so let's just decide. Alas, in order to cure this brother who stays at home all day, Yaoyao, I really work hard. After saying that, he jumped out of his brother's room and knocked on the door with joy on his face.

She didn't call him for her brother to run errands, it was all for his good.

"Brother, I'm out of drinks and snacks, can you buy some for me?" As soon as the door opened, Xu Yao's face immediately turned into a bitter gourd face, and she pulled up Xu Wu's arm and shook it constantly.

"No, your brother and I are busy. Go buy it yourself. "Xu Wu didn't compromise this time, he was really busy. I'm busy playing games, too.

Xu Wu's refusal surprised Xu Yao.

What's going on? My brother refused so quickly this time. He's really busy, but what can he do hiding in his room? I'm done with my papers, I'm not looking for an internship, what's important to me?

Thinking like this, Xu Yao's face changed again, and a little tear appeared in the corner of her eye.

"Brother, do you want your lovely sister to go out shopping at night? Do you know how dangerous it is? Maybe there is a fool hiding a few streets away, waiting for your sister and me. ”

"It's not dangerous for me to go. Xu Wu replied reflexively. Xu Wu, who was thinking about how to play the game, replied casually, without even thinking about it.

"What danger can you have, who fancy you!" Xu Yao also blurted out, and then realized that she seemed to have accidentally told the truth.

The black line continued to spread on Xu Wu's head, and he didn't speak anymore, silently shook off his sister's hand, closed the door, and prepared to continue to be his island master. He's really busy, and he just thought of a little idea, what if he forgets.

Xu Yao looked at the closed door, as if she saw her brother's dislike of her, and was afraid, if her brother never came out again, if she went down like this, where would anyone still look at him, no, no matter, I would pull him out. This is a must-do for Sister Sunshine.

"Bang Bang Bang"

Accompanied by the continuous sound of knocking on the door, Xu Yao shouted anxiously: "Brother, I was wrong, you are so handsome, many people must take a fancy to you when you go out." Don't be mad at me. ”

"I'm not angry, you go back, it's okay to not eat snacks all night. Xu Wu's bland response came from the room.

It's just that Xu Wu's bland response sounded to Xu Yao, and he only felt that his brother was really angry. I can't help but feel more distressed. But she also knows her brother that her brother will probably not open the door again at this time, and if she harasses him again, she is afraid that he will be even more angry.

I can only go back and find a way.

At this time, Xu Wu, who didn't know what his sister was thinking, kept writing some of his thoughts on a piece of paper.

Pave the way with moss first, then add more advanced plants, let the plants and microorganisms grow, provide a good environmental foundation, and then calculate how many consumers (plant-eating creatures and meat-eating creatures) this small environment can provide according to the 'law of tenths' of energy transfer, and the biomass input is lower than the calculated value first, so that even if something goes wrong, it is easy to adjust.

(The one-tenth law of energy transfer states that only one-tenth of the energy transfer in the food chain is generally used when it is transferred from the upper level to the next.) For example, when a rabbit eats grass, it can only absorb and use about one-tenth of its energy. ）

The general idea should be this, so what plants should be used?

There is a lake, and the resources invested cannot be wasted, so let's start with the water source.

Reeds are often seen next to the lake. There are also some aquatic plants that can be considered, I think, lotus, water hyacinth, red ling, and alocasia, begonia and the like. There are quite a lot of options when you think about it this way.

However, the water hyacinth will not be used for the first time, and it will be troublesome to overbreed, and when the water body is deprived of oxygen, the aquatic animals will not be able to live.

Wait, the problem of hypoxia is indeed very serious, aquatic plants, even if they are all white lotuses and the like, will consume too much oxygen in the water. Sure enough, quantity is a problem, do you have to master a degree?

So, start by planting lichens and reeds by the pool, water lilies in the lake, and planktonic plants to provide oxygen and nutrients.

What else can you grow on the shore besides reeds? Thinking of this, Xu Wu suddenly thought of the previous trip to West Lake. The willow leaves by the lake are fluttering, which is very beautiful.

Okay, let's have a row of willows, and then some ginkgo.

If this is the case, then what can animals use?

Plankton-eating fish and shrimp, small turtles eating fish and shrimp, fierce freshwater crocodiles?

Plant some grass on the shore, what are the grass-eaters?ants?locusts?lazy sheep and sheep?How can you not think of it??In addition to insect pests, it is anime, miserable, and the consequences are coming.

Xu Wu had never felt such a moment of great hatred for his usual house as he did now! Why didn't he go to the fields, the seaside, and the lake to visit more?

Time kept passing, although it was painful, but relying on the Internet and the method of constantly building a food chain around a point, Xu Wu spent three days, and finally, wrote a method that he felt was foolproof.

During this time, he didn't touch the game at all, and even forgot to go grocery shopping several times, and every time he got to the meal, he was in the knock on the door of his sister, saying thank you, taking the lunch box, silently closing the door and continuing to struggle.

Xu Yao's eyes became more and more worried when she looked at her brother's door, and she originally wanted to scold him, but when she saw her brother's silent and firm expression, she couldn't scold anymore, so she could only silently go grocery shopping, cooking, and delivering food. But the heavy feeling in her heart was getting heavier and heavier, and she had to do something.

Xu Wu naturally didn't know what his sister was planning, he took the thick stack of papers in his hand and shouted at the game device: "Hahaha, I'm here, my island." ”

Xu Yao, who was secretly eavesdropping outside her brother's door, covered her mouth and looked panicked!

"Oh no, brother, I'm really crazy. What to do, what should I do!"

Xu Wu opened the game device, and a three-dimensional operation interface was launched again. The voice of the phantom moon also sounded again.

Please select Archive. ”

Archive?

Xu Wu was a little puzzled, but saving is a normal function of a game, so naturally he didn't think much about it, he clicked on the start game option, and a new interface was launched.

Archive 1, Archive 2.

Yes, two save boxes appeared in front of him.

Which one is mine?

Xu Wu casually selected Archive 1 on the top.

A system prompt rang out: "This archive has been destroyed. ”

Speaking of which, Lao Chen Tou said that this game equipment was picked up by him, and the archive left by the previous owner? Xu Wu thought about it, and suddenly understood, and by the way, he mocked, the person who threw away this game equipment.

He retreated and chose save 2, and the familiar yellow-black desert island appeared in front of him again.

He magnified the blue dots of light on the island, and finally saw the small lake he had created.

"Phantom Moon, I will put 30,000 Candida algae, 30,000 green algae, 10,000 ascomycetes and 10,000 basidiomycetes on the lake. Tell me about it when they fill the lake. ”

"Okay. As Phantom Moon answered, a greenish-black patch appeared on the edge of the lake, and as time passed, the lichens continued to spread around, soon covering the shore of the lake and beginning to spread in all directions.

"Plant 100 reeds at half-metre intervals around the lake. In the lake are put phytoplankton (cyanobacteria, green algae, diatoms, etc.) and organisms. There are 1000 dog's tail grasses, 1000 ryegrass, and 1000 four-leaf clovers in these locations on the shore. Xu Wu followed his own ideas and began to invest in various aquatic plants and plants on the shore.

Ignoring Phantom Moon's exact answer, he watched intently at the change in the color of the lake. He had to put in the phytoplankton in the lake to eat them after they reached a certain base, otherwise they would die out in large numbers if they were overpropagated.

Being eaten is also death, being forced to die by competition is also death, and of course it is a death that contributes to the environment.

Xu Wu, who was serious, calmly watched the changes in the water surface of the island, and couldn't help but start to enlarge the surface of the lake. He was afraid that if he didn't pay attention, the phytoplankton in the water would grow a lot. Until now, he didn't know what the ratio of time to reality was in this game, and the last time he was not careful, the number of ants went crazy.

Constantly magnifying, Xu Wu suddenly found that the water surface was constantly approaching, and then suddenly disappeared, his surroundings seemed to be liquid, and he could even see some long or spherical shapes swimming around.

"Phantom Moon, what's going on?" asked as soon as he didn't understand, this was the experience that Xu Wu had summed up in the past few days.

"Don't you see those filamentous cyanobacteria and globular green algae in the lake you zoomed in? You don't know what you put into it? What a scum. Phantom Moon mocked the island owner unceremoniously.

Xu Wu, who was already a little guessing in his heart, couldn't help but exclaim after getting a positive answer: "Can it be magnified to the point of a microscope? What kind of game is this!"

A familiar look appeared on Phantom Moon's face again—contempt.

"Rare and strange, is it so surprising to magnify it five hundred times?"

If you look down from above, a huge island covers an area around Xu Wu's house, and the mycelium in the lichen of illusory light and shadow seems to be the size of a leaf. The strange thing is that no one saw this magical scene, what to do or what to do.

As for how many surprises this game can bring him, Xu Wu is no longer curious, and now he is only excited, intensely excited. An operation interface that can be operated at will, ultra-intelligent artificial intelligence, and a realistic ecosystem simulation.

Really, really awesome.

When the lake was slightly green, he immediately continued to issue instructions: "Put in 100 water lilies and 1000 river shrimp." The male-to-female ratio is 1:1"

Immediately around the lake, a hundred water lilies appeared scattered around, the leaves floated on the surface of the water, and the water droplets fluttered in the wind on it, and in such a piece of greenery, there were even individual lotus flowers blooming. It adds a bit of charm to this empty lake.

The algae floating in the water seem to have found a place of dependence, gradually attaching themselves to the rhizomes of the water lilies.

The river shrimp that have just been put in only feel as if they have entered a paradise, which is empty, no one is chasing them to eat, and there is a lot of food around them. The air is fresh and the water is sweet, it's just perfect.

With their full energy, they immediately began their journey of reproduction. Every day is to eat, swim, flirt with men or girls, and give birth to their own next generation. Clumps of shrimp eggs were in the abdomen of the river shrimp, and Xu Wu could still see the invisible embryo inside when he zoomed in.

The number of river shrimp began to increase in such an environment, until after turning several times, Xu Wu said again: "Put in 100 catfish." He didn't dare to throw too much, so he tentatively threw in a hundred catfish.

As soon as a hundred catfish entered the lake, they immediately went crazy.

It's not crazy, it's never been as stupid as a shrimp, it's all swam to the side and there is no response. How can you not eat the fat meat that reaches your mouth?

The long-term absence of natural predators made these river shrimp who grew up in the lake lose their vigilance, and this immediately taught them a lesson. A bloody slaughter was carried out silently in the lake, and the catfish opened their huge mouths and ate river shrimp one bite after another.

There are even individual river shrimp that attack the catfish they saw for the first time, and the catfish are very appreciative of this brave, courageous and energetic river shrimp, and personally rewarded them.

For the river shrimp group, today is the end of the world, but fortunately, the number of new catfish monsters is not large, only a hundred, which is not enough to threaten the growth of the river shrimp population.

Xu Wu naturally realized that the number of catfish could continue to increase, but he just looked at the rapidly declining biomass, and could only rely on their self-reproduction.

He ordered again: "Plant 100 willow saplings on the shore, by the way, while it is still safe, put in a little more tadpoles and dragonflies, and later you will definitely put in mosquitoes and butterflies and other insects to sow plants." Stocking their natural predators in advance can help curb their proliferation. Phantom Moon, plus 1000 tadpoles and 1000 dragonfly seedlings. There are also inputs, 1,000 earthworms, 300 crucian carp. There are also 1000 mosquito larvae and 100 potato seedlings at the same time, which grow at the same time. ”

Since mosquitoes are invested, it is natural that the food of female mosquitoes, the blood of animals, cannot be ignored. The shore was also covered with a full layer of vegetation at this time. Naturally, you can invest a certain number of animals as consumers.

Immediately, Xu Wu began a new batch of species input.

"100 rabbits, 300 voles. 100 pink rose seedlings. Butterfly larvae 100. ”

Again wait and see.

The lake is still a small world of river shrimp, and the shrimp with a tail wander leisurely in the lake, and the mouthparts are open and closed to devour small green algae and planktonic animals.

The big catfish held its white and chubby belly and slowly started a new round of predation. On the way, they met crucian carp, and they wagged their tails to say hello, and then each began their own hunting journey.

The water lilies in the lake have not changed much compared to before, but the leaves are much larger, and beautiful lotus pods once bloomed, and at this time lotus seeds are in it.

A frog that had just finished metamorphosis suddenly appeared on the water lily, a frog that had just climbed out of the water, and its body was still somewhat transparent at this time, and it began to sing its own song as soon as it appeared: "Frog ~ Frog Frog ~"

As if to be called, a frog on the shore, after sticking out its tongue and swallowing one of the target's mosquitoes into its stomach, also began to chirp, and the rapid frog chirping sounded from the reeds, making up a spring music.

Reeds flutter in the wind, fluttering tidbits and graceful willow leaves dance in unison.

The pink roses on the ground were also competing for beauty, but she looked around and couldn't find any opponents, and suddenly lost her energy, languishing and hanging her petals.

In the rose bush, a fluffy little vole, swaggering out, stretched out its pink little nose, nodded in the air and sniffed, and after a while, he found something, and walked on the eight steps of the king who did not recognize his six relatives, and set off towards the destination.

Why is it so inflated, you ask? Because it's the biggest, it's not the biggest, but it's the head, and there's no living creature here that can match it. Those creatures that can only jump around and burrow to graze are simply worthy of being its opponents.

It stretched out its noble claws and began digging in the target ground, soon seeing a yellow rhizome. Saliva flowed out, and it bit down into the fresh, tantalizing rhizome it had just discovered.

Holes in the ground are everywhere, revealing bitten potatoes, and some of them have even sprouted new sprouts. But more often than not, they are eaten directly.

Xu Wu asked Phantom Moon to list the data and development trends of all the creatures he had put in.

I hope to be able to fill in the gaps.
