To go to the underground black market, you have to prepare some goods for sale. According to Xiaomei, the underground black market that the group is about to rush to is divided into three grades: high, medium and low. The high-grade is the trade of technology and materials between the nearby big forces, which will be held at the No. 2 base, and the mid-level is the trade between the surrounding middle forces, which will be held at the No. 3 base. As for the No. 4 stronghold where Zuo Zhe and the three of them were going, it was the place where the surrounding small forces were trading. If Zuo Zhe wants to go to the No. 3 base or even the No. 2 base of the underground base, he must come up with enough valuable technical goods or enough money. Otherwise, Zuo Zhe would not have been able to enter the planets where the No. 2 and No. 3 strongholds are located.

There is no such thing as absolute strength and absolute weakness in this world, and both strong and weak are concepts derived from reference objects. For the core area and the vassal area of the Galaxy Empire, and even many frontier areas, the territory where Zuo Zhe is located is of course weak. However, in this relatively backward region of civilization, there are also forces of different strengths and weaknesses. And Zuo Zhe and these people are undoubtedly the weakest force, if it can be summed up by the term "force".

The more he understood, the more limited Zuo Zhe felt that his understanding of the world was limited, and the more he needed to rely on a native guide like Xiaomei.

Under Xiaomei's recommendation, Zuo Zhe wanted to sell some precious metals such as gold and platinum on this trip. Regardless of the fact that precious metals such as gold and platinum have a lot of reserves in most planets, the prices of these precious metals are still high. In fact, until now, the monetary system of the Galaxy Empire was still on the gold standard. The reason for this is that gold is a metal that can only be produced by supernova explosions, and it is one of the few metals. Moreover, if you want to mine and transport gold in remote areas, you need to pay a large amount of equipment transportation costs. Coupled with the need for humans, robots, time costs, transaction taxes, and the potential for encountering robbers such as interstellar pirates, the price of heavy metals such as gold has always remained high.

As for using the space teleportation circle, the question is, can they do spatial teleportation across hundreds, thousands, or even tens of thousands of light years?

In addition to gold, the only thing that Lucky Star can get his hands on is the robot's chip. Compared with selling robots, of course, selling robot chips is more profitable. If it weren't for the fact that she only had one ticket to the underground black market at hand, if there was a way to get more tickets, Xiaomei would have taken out those chips stored in the warehouse and sold them a long time ago. Although the chips stored by Xiaomei can only be regarded as low-end chips, there is also a large market in the black market.

"What do you eat on weekdays?" After roughly browsing the factory equipment that was so advanced that it was dizzying, but in fact it was impossible to understand at all, Zuo Zhe finally recognized his identity as a dumpling. No longer thinking about taking out the high-tech equipment in the space ring that had depreciated to the point of tatters, Zuo Zhe asked a very crucial question based on what he saw. Yes, Zuo Zhe didn't see even a single green leaf in the underground base and dungeon!

"What's wrong with eating compressed dry food?" I don't know why Zuo Zhe's brain circuit jumps so fast, Xiaomei asked suspiciously.

"Is it okay to just eat compressed dry food?" Zuo Zhe asked again.

"Well, compressed dry food has all the elements that the human body needs, not only food that can last a lifetime, but also a storage period of up to several decades. If it's in a place like Lucky Star where you don't need to worry about oxidation and external bacteria, compressed dry food will be no problem even if it is stored for a hundred years!" Speaking of compressed dry food, Xiaomei immediately came to her senses, and she didn't mean to be tired of eating at all. Why? Because compressed dry food also has different flavors! In Xiaomei's words, unless you are tired of eating, you can't get tired of eating compressed dry food, even if you eat it for a lifetime!

"Why don't you set aside a piece of land to plant some vegetables and fruits?" asked Zuo Zhe puzzled. With robots acting as farmers, it should be easy to do such a thing, right?

"That's not good!" However, Xiaomei waved her hand again and again, "We carry a lot of bacteria and viruses on our bodies, and if we build an ecological park, it is possible to spread those bacteria and viruses in our body that do not have a chance to reproduce." In case those dormant bacteria and viruses spread to vegetables, fruits and even meat, they will spread to other planets with our interstellar travel. On the contrary, if we only eat compressed dry food, although the food is monotonous, when we enter the ecological planet, it is not easy to be locked in the health room for detoxification because of the bacteria and viruses hidden in the body. ”

Therefore, it was not until this moment that Zuo Zhe knew that he had to do a major examination of all aspects of his body when he entered the ecological planet. By the way, this is a necessary check for vulnerable groups like Xiaomei who have no background and no access. If you have access and background, it is possible to simplify or even eliminate the inspection altogether. If Xiaomei doesn't want to undergo an overly complicated health inspection, Xiaomei will have to bribe the health and quarantine personnel in charge of the inspection before entering the ecological planet's atmosphere. In contrast, going to the desolate planet where the underground black market is located does not require such a health check.

Originally, Zuo Zhe thought that the fruits and vegetables in the space ring could be sold as luxury goods, but now it seems that it is enough. It's not that Xiaomei can't get plant seeds or ecological parks, it's just because they're worried that there will be more abnormal bacteria and viruses in their bodies. From this point of view, it would be much more difficult to use the smallpox virus in the same way as it did against kingdoms such as Roland and Rose in the Spiritual Power Continent.

If there is only gold and low-end chips produced by Lucky Star, it will not be sold for a large price. If you can't sell it for a large price, it means that Zuo Zhe can only go to the lowest base No. 4 to trade on this trip. Then, after this transaction, it is likely that you will not be able to get more tickets to the underground black market.

As for taking out the space ring and selling it as a commodity, Zuo Zhe would not do it at this stage.

For a while, Zuo Zhe didn't know what to sell. The food in the space ring may be at risk due to bacteria and viruses, and in the face of compressed dry food with a good taste, even if it is somewhat competitive, it is difficult to sell it at a high price. Moreover, even if he can sell it at a high price, Zuo Zhe does not plan to make money by selling food. Once someone with a heart discovers food that shouldn't exist in this place, it's going to be a problem to be investigated. In contrast, Zuo Zhe is more inclined to sell industrial products, handicrafts, and knowledge.

"Xiaomei, what do you think of this song?" In a separate room, Zuo Zhe played a classic song from the earth to Xiaomei.

"It's good. Xiaomei said with interest after listening. Other than that, Xiaomei had no other reaction. As for soul resonance? That's non-existent. And the existence of the spirit of heaven and earth does not have the slightest sign of appearing.

"It doesn't seem that all planets have Star Clans, and I don't know if there are Star Clans on the ecological planets within the Star River Empire. Very disappointed in his heart, Zuo Zhe asked unwillingly, "If I hold a concert dedicated to playing these pieces, are you willing to pay to watch it?"

"What do you want to do, do you want to rob money?" Hearing this, Xiaomei immediately looked at Zuo Zhe vigilantly, and hurriedly covered the space ring she had just obtained in her hand.

At least Xiaomei doesn't have the consciousness to get tickets for concerts. And Xiaomei's next words perfectly prove this, "Even if I like to listen to music, I won't pay for it." If I have to go to see it, I will remotely control the mechanical gecko to find a safe place to lie on my stomach and watch the concert through the feedback screen of the mechanical gecko. Because of the huge cultural differences, Xiaomei is very unfamiliar with the concept of "fans". In Xiaomei's view, worshipping each other because of who sings and sings well is an incomprehensible stupidity. In Xiaomei's simple cognition, there are only three kinds of people in this world who can make her admire, the first is a powerful general, the second is a scientist with extraordinary intelligence, and the third is a businessman who controls a huge amount of wealth.

Well, the idea of starting a concert to earn tickets or live streaming fees has failed. However, this does not mean that Zuo Zhe will give up exploring ways to make money. After racking his brains, Zuo Zhe quickly remembered a way to make money.

"What if it's an online game?" Pulling out the laptop in the storage ring, Zuo Zhe opened a large 3D single-player game.

Then, then Xiaomei, who had already learned Chinese, fell into it out of control!

"Don't disturb me, I want to play a game!"

After seeing Xiaomei's reaction, Zuo Zhe's hanging heart finally let go.

It wasn't until the battery of the laptop was exhausted and the laptop screen went black that Xiaomei broke free from the game.

Grabbed Xiaomei, who wanted to add a power cord to her laptop, Zuo Zhe asked his own question again, "Are you willing to spend money on this game?"

"No!" Xiaomei replied very decisively and crisply.

"Why?" asked Zuo Zhe, puzzled.

"I can crack this game, why should I spend money in vain?" asked Xiaomei rhetorically. Therefore, single-player games are worthless in the Galaxy Empire. It is precisely because of this that no one in the Galaxy Empire will develop single-player games for sale. In other words, if you want to make money, you can only launch an online game that is difficult to crack. Moreover, this online game has to elevate the player's character to a very high status. Like a large-scale role-playing game, it is also easy to crack. Therefore, Zuo Zhe feels that online games such as "League of Legends" and "CrossFire" are more suitable. Of course, if you really want to make money, you have to make some local changes. If you're going to launch League of Legends, it's best to use a holographic helmet that can make you feel like you're in the middle of the action. This kind of technology is not difficult for the Galactic Empire, but no one in the Galactic Empire has yet to use holographic helmets for playing games. In addition to using holographic helmets, it is also necessary to make the game difficult to crack, minimize game bugs, and increase the punishment for cheating.

In other words, Zuo Zhe's initial thought was obviously to find a mad scientist and create a spirit plant, but now why does it feel a little off-topic?
