The protagonist wants brighter lighting and doesn't like the presence of ant waste in the room, regardless of whether or not it emits an unpleasant smell. The brighter fluorescent bacteria are more likely to grow on the more flavorful feces of male ants and queens.

However, fluorescent bacteria are the only underground light source for ants, and fires cannot be popularized, and electric lights cannot be invented

Fortunately, the protagonist was inspired by the practice of cultivating fungi by humans, and cultivated clean fluorescent bacteria, thus solving this problem.

Mushrooms are used to being called mushrooms, which are different from plants, which can photosynthesize to obtain nutrients, while mushrooms do not have chlorophyll and do not produce nutrients on their own, but can only use their mycelium to reach into the soil or rotten wood to absorb ready-made nutrients to sustain life.

Therefore, mushrooms often grow in warm, moist and organic places. In order to obtain nutrients, mushrooms are widely distributed throughout the world, and are most abundant in the deciduous areas of forests, as well as in patches of miscellaneous forests and shrubs, grasslands, fences, rotten trees, and even dung heaps in forest edge areas.

Under natural conditions, although the yield of mushrooms is not low, there are too many types, and many mushrooms are poisonous, and the appearance of some poisonous mushrooms is extremely similar to edible mushrooms, and even many veterans are difficult to distinguish. Every year, there are many gourmets who die from eating delicious wild mushrooms.

After people's exploration, they have gradually mastered a set of artificial mushroom cultivation technology, and concentrated on planting some safe edible mushrooms, which have the advantages of high yield, good safety, easy management and collection.

Taking the common shiitake mushroom as an example, it is rumored that the earliest cultivation of shiitake mushroom was Wu Sangong, a native of Longyan Village, Longxi Township, Longquan County, Southern Song Dynasty, and in the history of human shiitake mushroom cultivation, the earliest and most complete documentary data left behind is 1209 A.D., that is, the record in the "Longquan County Chronicles" compiled by He Tang in the second year of Jiading in the Southern Song Dynasty.

Modern cultivation of shiitake mushrooms is mainly carried out in the following ways:

First of all, set up a mushroom farm, it is best to shelter from the north wind, sunny land, good resources, close water sources, shade, gravel, acidic gentle slope land. Remove dead branches and leaves, bark, roots, etc. from the site, level the land, build a shade shed (2 m high), and sprinkle lime on the ground for disinfection.

The second step is to choose the right mushroom tree.

, then cut down the tree, dry the logs, and cut off the branches.

The third step is manual inoculation, which can be inoculated at a temperature of 5~20 °C, and the monthly average temperature is about 10 °C. Punch holes in the treated mushroom trees and insert the fungus. After inoculation, seal immediately to prevent the invasion of rainwater and miscellaneous fungi and insect pests, reduce water evaporation, and protect the growth of mycelium.

The fourth step is to pile up the fungus, put the inoculated segment of wood on the mushroom field in time, and then strengthen management, do a good job of moisturizing and heat preservation, checking the survival rate of the fungus, turning the pile, shading, and controlling pests and miscellaneous fungi.

The fifth step is to get off the shelf. After inoculation, in warm areas, the mycelium is basically mature in late winter and spring for about 8-9 months. However, in cold areas or when the mushroom tree is too large, it takes two summers for the mycelium to develop to the extent that the mushroom emerges. At this time, the mushroom wood should be moved to a place suitable for the formation of fruiting bodies, and the mushroom wood should be raised to allow it to emerge.

To start the frame, lay a wooden stake first, put a horizontal log about 65cm from the ground, and the two sides are herringbone and staggered. After the mushroom is scattered, attention should be paid to hydration.

Finally, it is harvested, and the mushrooms cultivated by Duanmu can be inoculated at one time and produce mushrooms for many years.

It is also possible to use a variety of agricultural and forestry by-products as the main raw materials, such as sawdust, etc., to add an appropriate amount of auxiliary materials to make a culture medium to produce various edible fungi.

No matter what kind of fungus is cultivated, the most important thing is to maintain the temperature and humidity and make the medium, and the underground with constant relative temperature and humidity is suitable for cultivating the fungus. What the protagonist needs is to find a medium to replace ant dung, so that he can perfectly grow fluorescent bacteria that are originally adapted to the environment of the ant nest.

After some experimentation, he found that the fluorescent bacteria planted on the fat masses grew best and had the highest brightness.

Come to think of it, fat is the well-deserved leader in terms of energy density among all kinds of foods, and it is no wonder that fluorescent bacteria that have been living on relatively poor feces like this medium.

If it were put in other ant nests, there would be no place where they could be so tyrannical, using their precious fat to grow lowly fluorescent bacteria that could survive by providing feces.

But the protagonist has a large-scale mealworm farm, which can provide a lot of insect fat. The fat is cut into cubes and baked to reduce the volume, making it a suitable medium. Transplanted fluorescent bacteria can grow extremely lush on it and maintain its brightness for more than a month.

In this way, the protagonist's dormitory finally uses a relatively clean light source, and only here will use such a luxurious light source, and fluorescent bacteria in other places are still cultivated in traditional ways.

On the two sides of the protagonist's courtyard, there are two large nest rooms, one nest is inhabited by Janissaries such as Mulan, and the other nest is inhabited by a group of worker ants who serve the protagonist.

Mulan is the first big-headed ant to follow the protagonist, and has been following the protagonist not long after the protagonist breaks the chrysalis. Now Mulan has entered the middle age of ants, and her physical condition has declined, but the protagonist still takes her with him.

In the Praetorian Guard team, many soldier ants are old acquaintances of the protagonist, such as Force 3 and Wei 1, both of whom were accompanied by the protagonist when he left "Dongyang City" for the first time, and there were a total of 24 soldier ants at that time, but for such a long time, some died in battle, some died of old age, and some Zhuang 1 returned to Lao Wang and disappeared after being infected by parasites, and in the end, only 4 soldier ants remained with the protagonist.

The protagonist is also kind to these old subordinates, and they are incorporated into the Praetorian Guard squad, and the protagonist's Praetorian Guard squad rarely participates in fierce battles now, just so that these subordinates can retire.

With the protagonist not planning to leave "Dongyang City" for a short time, the Praetorian Guards, who often accompany the protagonist everywhere, can finally have a good rest.

The worker ants on the other side who serve the protagonist are all carefully selected smart worker ants. These worker ants are selected from the moment they break the pupa and are not allowed to do dirty work such as cultivating fluorescent fungi or digging in the soil, because their large jaws are used to carry food for the protagonist, and there must be no contamination in the slightest. This is the only bit of cleanliness that the protagonist insists on after crossing into an ant.

A path directly from the courtyard leads to the protagonist's apartment.

Only the protagonist lives in the room, and on weekdays, whether it is a Praetorian Guard or a worker ant, they can only stay for a short time.

As soon as you enter this room, you will find that the nest here is not a circle, but a standard rectangle!
