For runes like this that can produce water vapor, the white wolf made 5 in a row, placed them around the culture material in order, and used a few scattered lines to string these rune arrays together.

These rune circles that are connected together will be used alternately, through this way, the long-running rune circles can have a rest time, so that the loss of the rune circles can be minimized, the five circles together can be used for about 10 years, such a long time is enough for the goblins to find other ways to obtain food, and the white wolf has no intention of being the eternal nanny of this goblin tribe.

Although these water vapor generator rune arrays have both water and fire elements, they are set by the white wolf as the fire activation method, that is, they can only be activated by entering the fire element, and the small wooden staff handed down by the goblins can be used as the key to open the magic circle, as long as the small wooden staff is used to input a small ignition element into the rune array, it can be activated, and when the temperature is high enough, these rune arrays will automatically turn off to avoid excessive temperature around the mushroom.

The thick leaf mushroom is planted, the next is the fish fishy mushroom, this kind of mushroom is much easier to grow than the thick leaf mushroom, the fish fish mushroom likes a cool and humid place, as long as you put some rotten wood culture material in the shade, and then lead some fish fish mushroom to the rotten wood, the fish fish mushroom grows very fast, and will soon be covered with a whole piece of culture material, but compared with the thick leaf mushroom, its edible value is much lower, the specific performance is that its umbrella is only a quarter of the thickness of the thick leaf mushroom, at least the ability to fill the stomach is not as strong as the thick leaf mushroom.

The mushroom planting method of the white wolf is quite simple, first of all, it is required to collect quite a lot of wood chips, so the crunchy rotten wood is the best choice, use the stone to mash the rotten wood into crushed to make a culture material, if you are not too troublesome, you can also add some leaves or crushed straw to it, in fact, as a culture material, the best choice is actually a corn cob, but the white wolf did not find a crop similar to corn, if he could find corn, he would have planted corn a long time ago, so he would not plant any mushrooms.

Add some river water to the mixed culture, stir it well, and then spread it on the ground, and there is another process before sowing, that is, sterilization and insecticide, if you don't do this process, insects will grow in the medium, causing a decrease in yield, but the white wolf is very suspicious, these goblins may prefer to eat insects to mushrooms.

However, sterilization and insecticide are still necessary, otherwise, if poisonous bacteria grow, it is easy to have food poisoning, and some poisonous mushrooms and fishy mushrooms look quite similar, and the white wolf himself can't tell the difference, and he has no confidence to teach goblins to do this.

In the original world of the white wolf, the work of sterilization and insecticide can be completed by fumigation with low concentrations of sulfur, potassium permanganate and other solutions, and similarly, the white wolf has not been able to find a drug with insecticidal and sterilization effects in this world, so he can only find another way to use magic runes to complete this process.

The white wolf's idea is quite simple and violent, directly construct a thunder element rune array with extremely high strength, put the cultivation material on it, and then activate this rune array.

Once the rune circle is activated, it is not enough to ignite the sawdust, but the electrical energy that will electrocute all the bacteria and insects hidden in the culture material will be excited from inside the circle, but unfortunately, this rune circle white wolf has not been able to fully make, because his recent energy is focused on building water element runes, so he has delayed the research progress of the rune array inside the "thunder" crystal, and he has not yet completed the mastery of the thunder element runes, so this process can only be postponed temporarily, until the white wolf puts the "thunder" The crystal analysis is almost done before there is a chance to make it.

The goblins watched curiously as the white wolf knocked on a pile of wood near their cave, and thought it was fun and curious, and the next day, they found that small mushrooms had grown on the wood chips, although they were not enough to eat, but they were still quite surprised, and many goblins thought that the white wolf had used magic on this piece of wood, so that the wood could grow food overnight.

"No, don't you? You don't even know how to grow mushrooms from rotten wood? How did you find mushrooms when you were underground?"

"What we eat underground is a kind of mushroom that can glow blue, this kind of fluorescent mushroom can only grow in special land, and it is the first time we have seen mushrooms grown from wood, in fact, before we came to the surface, we have never even seen such trees, and the plants in the ground are much smaller than these trees. It was the Goblin Patriarch who answered the white wolf's question.

The white wolf thought for a while, and felt that the goblin patriarch was right, he took it for granted, the underground and the surface were originally two different worlds, and the ecosystems were of course different, and he took it for granted that the goblins knew how to grow mushrooms, and it was he who carved the boat to ask for a sword.

But to be honest, the goblin patriarch's words instead mobilized the white wolf's curiosity for the underground world, there is no underground world on the planet where he used to live, it will be a place that violates most of his common sense, thinking of this, the white wolf can't help but be eager to try, his spirit of exploration has been hooked, but it is obviously not time to explore the underground world in front of him, he has to solve the problem of the goblin tribe before exploring.

The task now is to teach these goblins to learn other processes of growing mushrooms, in short, first take advantage of the goblins' curiosity about growing mushrooms, teach them to grow mushrooms, usually only when they see results, a person's enthusiasm can be sustained, and goblins are the same.

The white wolf spent a lot of effort to teach these clumsy goblins how to crush wood chips, how to make culture materials, how to grow mushrooms on top of the culture materials, how to turn on his water vapor generator, the process of teaching made him exhausted, these goblins' ability to learn is really poor, even let them memorize a simple way to deal with rotten wood It takes a long time, the only thing that makes him feel more relieved is the smartest passerby in these goblins, C, he only used the white wolf to teach ten times to learn the white wolf's rotten wood processing technology, and the other goblins have to learn dozens of times to learn, holding a bunch of leaves, directly using a whole freshly cut wood, When it came to a pile of water, all kinds of strange behaviors made the white wolf a little annoyed, but fortunately, there was a passer-by C who maintained the intelligence level of this goblin tribe, otherwise the white wolf would really think that this race was out of play.

"Well, that's the end of it. Looking at the pile of green creatures busy next to the wood, the white wolf wiped the sweat from the top of his head and began to study the "thundering" crystal around his neck.
