If Li Er wants to do a round-the-world trip, it is not a matter of making a trip, you know, although this round-the-world trip is very fast, but Li Er will definitely understand some of the current situation and history of various countries along the way, so it is not a day to do it, so he still needs to prepare, at least the court side must explain well.

And Yang Heng also took this opportunity to have a good understanding of the spaceship, you know, before, Yang Heng also had a good understanding of the spaceship, which was not very thorough.

For example, how the plant planting cabin works, whether it uses soil or nutrient solution, these are not understood, and now, the first thing Yang Heng needs to understand is this place.

"The plantation is here." After Yang Heng inquired, he found the control system about the plantation in a corner of the command cabin, "Foaming agent, what is this?" Yang Heng saw the introduction and said, first of all, we must prepare the foaming agent, the foaming agent is in the plantation's foaming agent manufacturing storage room, it can be understood from the literal word, this foaming agent is temporarily manufactured, however, there are also manufactured and stored.

Look at it again, "Yes, this is the actual picture of the foaming agent after molding, this, isn't this similar to the sponge-like thing in the previous life, oh, it's still different, this one is very strong." "When the foaming agent is sprayed into the plantation, it will turn into a white spongy object, and this object, called the plant fixation base, that is, the plant is planted in it, and the root system of the plant will grow between the voids in it, and then this fixation base can store a large amount of nutrient solution. Even. The nutrient solution chamber is connected to this fixed group. Once the nutrient solution in it is lacking, it will be quickly replenished, and even, within a certain period of time, there will be a sprinkler to spray water on the plant, which is to imitate rain.

As a nutrient solution, there is also a nutrient solution processing center, this processing center. Part of it is to convert some of the various minerals prepared in advance into nutrient solution, and part of it is to convert the garbage generated in the spacecraft, and even some waste gas into nutrient solution after treatment, the same way, this fixed base also plays a role in filtration, and there will be a water output port on the other side of the fixed base, which is an important part of the water recycling inside the spacecraft, and the water that comes out of the fixed base is qualified mineral water. It can be eaten directly, which is why it is used when traveling for a long time. One of the reasons why you can't bring too many people on the spaceship is that the garbage processing function can't keep up, and in a short period of time, you can consume some stored items, as well as consume some recycled items, and if you bring more people, once it takes a long time, it will cause an increase in garbage, a decrease in various storages, and a lack of recycling output. All in all, the spacecraft is limited.

After checking here, Yang Heng decided to conduct an experiment on this botanical garden first, but what is good to plant, just choose the same ordinary grain, rice, by the way, and then choose a wheat.

Soon, Yang Heng used a horse-drawn cart to transport wheat seeds, as well as rice seeds, as well as several mineral deposits needed, this, there is no need for Yang Heng to transport them personally, Yang Heng only needs to transport these things to a designated location, and the spaceship will automatically absorb enough water from the rivers on the side, and quickly transport them to the location where they should be placed.

"May I ask the marshal, whether to plant wheat, rice, wheat can be planted in nine equal divisions, rice seeds can be planted in seven equal divisions, there are sufficient water sources, there are sufficient minerals, whether it enters the automatic circulation system." "Yes." With Yang Heng's yes appearance, I found that there was a change on the screen, first of all, there were two isolation pools in the botanical garden, which should be a nine-square, a seven-square-meter container as the system said, and then a layer of white liquid appeared at the bottom of them, and soon, these liquids began to foam, and soon, they were all over these two containers, however, Yang Heng did not see the so-called input pipe, and the output pipe, it seems that this is hidden at the bottom, however, there are some instructions on the screen, such as, The fixed base shows the words 100%, minerals, nutrient solution, is the words that show some ratios, the output of the nutrient solution, slowly growing, and then, there is the word "planting rice", planting wheat, and completion, and in terms of resource circulation, it is still zero at this time.

It seems that this will have to wait for a long time, you know, the seed from germination, to the seedling, it takes a certain amount of time, what is this, there are two physical seeds on the screen, or a profile in the fixed base, in addition, simulating the atmospheric environment, humidity, temperature, wind, this, in the botanical garden is the existence of a microclimate.

"Twelve hours before the seeds germinate." This monitoring is too sharp, and the time is given, but, if you think about it carefully, it is also, since it is a small environment, then, it will have the temperature of breeding.

Okay, let's let it grow on its own first, and then learn about the rest of the ship.

Yang Heng came to the main control screen again, "This is?" Yang Heng suddenly found a detail, some of the flashes on it seemed to be a little different, so Yang Heng quickly pulled out the display of the earth, when it was enlarged to the size of a ping pong ball, he found that the planet seemed to be rotating, and even, it was still moving slowly on the screen, look carefully, it was not the planet that was moving, but the other starry sky was moving, that is to say, the planet was in this fixed position, but there was a set of numbers on it, which was constantly changing, rightThis is the azimuth coordinate transformation of the space where the planet is located, and where is it used as the reference point?

Also, in the distance, there is also a brighter shining point, Yang Heng clicked that point again, this is, the morning star, however, this is just a bright light, it will not show anything on the surface of the planet, and there is also a set of numbers that are constantly changing.

"Marshal, have you calculated the route of the wormhole between the two planets?" "This wormhole route can be calculated, isn't the wormhole fixed?" Yang Heng involuntarily asked.

"Back to the marshal, our spacecraft will simulate wormhole navigation in interstellar navigation, as long as the standard azimuth coordinates of the two planets are given, the spacecraft will be able to sail in space in a wormhole way, not to say, sailing in a wormhole, and there are natural wormholes in space, these natural wormholes are also the safest way to explore unknown star fields, after answering, if the marshal still has questions, please go to the system database query."

I understand, these stars displayed on the screen naturally have their fixed coordinates, however, this coordinate is changing at all times, that is, the planet is always in motion, and I don't know how much computing power this system has, and it actually calculates the transformation of all known galaxies all the time, and even, after Yang Heng just loaded this spaceship with energy, it actually calculated this galaxy map in a very short time, you know, at the beginning, Yang Heng didn't find those coordinate data when he clicked on the planet, that is to say, at that time, these data were not available, so that is, in the past few days, the system quickly calculated it according to the database.

By the way, this looked at the botanical garden and the ecological circulation system on the spaceship, but Yang Heng didn't know much about the defense of this spaceship, as well as its weapon system, where is this.

"Defense, force, ......" Yang Heng muttered while looking for it in the control cabin, this, maybe as the general control, there will be a part of the control power, but he can't take care of everything, there will definitely be a division of labor.

"This is, a temporary seat." Why do you say that, because, Yang Heng found that this place was a little out of place with the configuration of this cabin, so let's click on it first.

"Report to the marshal, this is the general control of His Majesty the Emperor, His Excellency the Marshal has no control, please forgive the marshal." "Oh, I said it was added temporarily," an expedition ship, it is impossible to have the location of the emperor, it is naturally added temporarily, and as the position of the marshal, it is just a change of name that this spaceship has added the position of the emperor, but its general control is still controlled by the commander, but now the commander is directly promoted to the marshal, this does not need to be changed, however, there is now an additional authorization, that is, some orders must be authorized by the emperor to be executed, just like, If this spaceship is to sail, it must be authorized by Li Er, because Li Er, the emperor, has already registered on the spaceship, but he has not yet arrived at his seat to operate.
