The third level to the fourth level requires a consumption of 100,000 taels of silver.

But it doesn't matter, let's not talk about the sporadic expenses such as daily food consumption, daily necessities consumption, and valuable commodity consumption, but only the military expenditure and medical drug expenditure in the later period is the big one. However, the price of drugs is relatively cheap, even if the quantity is large, it cannot form a consumption scale, but the military part is okay, the price is lower than that of this era, but it is always the most expensive and the most purchased product.

TOEFL, in just over half a year, Zhang Hongbin completed the consumption of 100,000 taels of silver.

Now, all he needs to do is find a secluded place, turn the system on, and choose to upgrade.

To be able to complete the fourth-level upgrade in less than two years, whether this speed is fast or not Zhang Hongbin doesn't know yet, according to his understanding, those consumption powers should be faster, and he can only be regarded as average at best.

But it doesn't matter what, at least there is no sign of a second traverser in this plane, and no matter how slow he upgrades, it won't have any effect. For example, at the beginning of the game, you chose the Heaven level, and you can clear the level by playing with your eyes closed.

I explained that I didn't want anyone to get close to the study, but my own was connected to the system, and the whole person's consciousness instantly entered the system supermarket.

As before, the first layer is the product of some raw materials or rough processing, that is, things that can be created without any technology. But it cannot be denied that even if the gunpowder in it is black powder, it has a great impact on its own forces. It's just that due to the level of the problem, there is still a certain limit to the amount of gunpowder that can be purchased in a month, at least not more than five tons. And what is depressing is that the gunpowder is only refreshed every three months.

According to the shopping guide, it is naturally okay to hoard a large amount of food, but in the future of Huaxia, the control of gunpowder and knives is still very strong. In particular, if gunpowder is purchased in large quantities, it will still attract the attention of the government. Whether it's to keep the profits thin or to avoid unnecessary trouble, the system is only able to supply a batch of five tons of gunpowder every three months.

After deducting the amount of gunpowder consumed in the process of making granular gunpowder, this batch of gunpowder was only able to produce about 3.6 tons of granular gunpowder. It seems like a lot, but when you count the daily consumption and wartime consumption, these 3.6 tons of granular gunpowder can only last for three months at most. This is when the territory does not have a large number of armed grenades, mines, and firearms.

Zhang Hongbin also looked at the gunpowder that still hadn't been refreshed on the first floor, and went directly to the second floor.

On the second floor, there are rough daily necessities. and the emergence of books, luxury goods, medicines, weapons, and hardware. Well, most of them are elementary things, such as luxury goods are wine and tobacco, books are enlightenment books and some commonly used livestock breeding techniques or something, weapons are strong crossbows and composite hunting bows, and hardware products are some relatively rudimentary, such as hammers, screws and screwdrivers.

This is equivalent to pointing out to Zhang Hongbin the direction of upgrading and development of a supermarket.

The first is luxury, the most effective thing to do favors and win people's hearts, especially from future technology, which can attract the attention of the natives of this era, even if most of these so-called luxury goods are copycats.

The second is hardware tools, which are tools. Nowadays, it is the simplest tool, and in the third layer, it has developed into things needed in industry and physics, such as measuring instruments and rangefinders, and even sextants, which can be used on the sea. If it continues to develop, there may be a variety of electric and smart tools, such as computers, lathes, and so on.

The third is books, from the most basic enlightenment to more and more comprehensive knowledge, 'knowledge is power' is an eternal classic saying, which tells us that as long as we master knowledge, it is equivalent to mastering the initiative, mastering the future, and mastering a qiē!

The fourth is medicine, this one doesn't need to talk nonsense, from the most basic cold medicine to antibiotics, they are all good medicines to cure diseases and save people...... As for those copycat Chinese medicines, it is not nothing, but Zhang Hongbin really dare not use them...... Maybe it's possible to test it on humans?

The fifth is weapons, from the original self-defense small arms, to today's peak works of cold weapons, seeing the beginning of the fourth level, I am afraid that it is the appearance of firearms. And what about the future? Will there be a cloud burst or even a nuclear bomb for sale?!

"I have checked that the user's consumption meets the upgrade conditions, is it upgraded?" The shopping guide finally asked a question after Zhang Hongbin bought a bottle of milk.

"Level up!" Zhang Hongbin opened the milk and drank it.

Well, it tastes like a chemical additive with milk in it...... It's real milk, not creamer......

The upgrade of the system is a little slow, and even a progress bar appears in Zhang Hongbin's mind, watching the number of jù rise little by little, it is really a bit maddening after a long time.

"Couldn't the system be upgraded faster?" Zhang Hongbin asked a little complainingly.

"Since the fourth layer, the level of technology has begun to approach this era, and the obstacles of time and space will increase, and this situation will become more and more powerful with the increase of the supermarket level, so the upgrade speed will become slower and slower. At the same time, the resistance of new products to travel through time and space will also increase, which will also increase the cost, so when it is sold, the selling price will also rise appropriately. "The shopping guide was very kind and said very inappropriate words.

According to her meaning, the so-called time and space travel cost will still be counted on the head of him, the consumer, in the end. Well, supermarket upgrades require enough consumption, so it is not necessarily a good thing for the price of goods to go up...... At most, I can't get over it.

The whole upgrade process continues, and at the rate of progress of this progress bar, I am afraid that there is no way to complete it in two hours.

Simply exit the system directly.,Anyway, the system will be upgraded directly.,Even if you quit the system.,This is what I asked the shopping guide.。 After getting out of the system, Zhang Hongbin saw that the time was almost up, so he simply called Chunxiang and Yang Ai to have lunch together.

According to the habits of this era, men and women are not allowed to share the same table, let alone two women who are still Zhang Hongbin's maids. However, if Zhang Hongbin eats alone, even if there are two beauties around him, even if one is accompanied by a little girl, he feels that the food will not be sweet, so he simply tells them that they can eat together at the table when there is no one.

The two regarded this as a favor, but they were a little more grateful to Zhang Hongbin, and it was rare to eat together, but they couldn't change their restrained attitude. Even if Zhang Hongbin intends to clip dishes farther away, they will try their best to help clip Zhang Hongbin's bowl as soon as possible.

Well, it's a live meal for yourself, right?

It's a pity that Chunxiang is still a little young, and as for Yang Ai's little maid, she is only twelve years old, and it will take a while to say goodbye to the boy. Well, yes, Haruka will have to wait at least a year to make it a little more round, so that it can feel good. Zhang Hongbin, who is a chest star, said that if a woman has no breasts, she is not a woman at all, and if she is entangled with a person who is not a woman, it will not be sexually aroused at all.

"Young master, Sister Yang seems to be planning to make Mother Liu her godmother recently!" After the meal, Chunxiang made fun of Yang Ai.

"It's not, it's the slave family who thinks that Liu's mother is kind, so they plan to recognize a godmother......" Yang Ai didn't deny it, but just denied the matter of recognizing the godmother.

Perhaps, I think that godmother and godmother are different concepts, and godmother means that Liu's mother has become her mother, and if she is a monk, her husband must also recognize Liu's mother as her mother. If the husband is lowly, then it is enough, if it is noble, how can he tolerate a subordinate who cooks and cooks to be his mother?

"In other words, you're going to change your name?" Zhang Hongbin asked casually.

"Yes, if I recognize this godfather, then I am also a member of the Liu family, so I should naturally change my surname to Liu." Yang Ai nodded.

"Liu Ai, this name is not bad, but why does it feel so similar to Liuai?" Zhang Hongbin said with a smile.

"It's true that this name doesn't quite fit the meaning of the slave family, so the slave family plans to change the name even as well. It's just that I haven't figured out what to change it to......" Yang Ai returned.

"You can just think about it, and then let me refer to it after you think about it." Zhang Hongbin waved his hand and confirmed the conclusion.

The meal was completed in this way, and the system had just completed the upgrade, and Zhang Hongbin simply hid in the system.

Above the third floor, a new floor appeared. Unfortunately, the elevator was not opened on the sixth floor before, so you still need to walk up and down by yourself.

Compared with the third layer, the fourth layer has a lot of new colors that you can't see even in the future. Whether it's new food or new daily necessities, there's something here. Zhang Hongbin naturally asked the shopping guide and came to the conclusion that the products here were all products that were about ten years beyond the time and space before Zhang Hongbin traveled. In the past ten years, the technology of Shanzhai has been further expanded, and the science of that time and space has also been greatly developed, so it is normal for new products to be available.

It is precisely because of this that the shopping guide told Zhang Hongbin very definitely a long time ago that there is a repair solution on the fifth layer, which can help him remove the scars on his face. If it weren't for that, Zhang Hongbin would naturally be reluctant to give up his handsome face.

With curiosity, Zhang Hongbin looked at the prices of the goods, but they were more expensive than those below the third floor. But it doesn't matter, the increase is not large, and it belongs to the type that can be bought in large quantities and sold at a high price.

Of course, what he wanted to see most was not these things, but the five areas that had been enclosed.

It's just that what makes him want to cry is that the consumption amount opened in each area is 10,000 taels of silver, in other words, unless he consumes 50,000 taels of silver, these five ranges will never be opened. Fifty thousand taels, another insurmountable ravine.

The reason why it is not said to be a chasm, but the amount of consumption required to upgrade from the fourth level to the fifth level is 500,000 taels of silver, which is a gap that can only be crossed in a year and month!
