The fifth-level backpacks are so powerful, and the sixth-level backpacks are even more incredible.

The Level 6 backpack is 200 slots, except that it also has an effect that almost all players wanted to have at the time, that is, the food in the backpack will enter a 'fresh' state, as long as it is not taken out, it will not spoil for a lifetime, let alone rot.

In fact, it is not only food, except for some special items, but all items that will rot and deteriorate can be kept fresh forever when put in the backpack.

Although these backpack functions look very powerful, according to a certain statistical result of Su Yu's game at the time, among all players, the players who successfully upgraded to level four accounted for only 2% of the total number of players in the game, only 0.4% of those who were promoted to level five, and less than ten people who were promoted to level six.

As for players who have reached level seven...... Not a single one.

Su Yu only upgraded to level six and then gave up upgrading, although she had the ability to purchase materials to upgrade the level seven backpack, but because the consumption and harvest were completely disproportionate, plus the two hundred grids of level six were completely enough at that time, so she did not continue to upgrade.

In the middle and late stages of the game, lord players don't say they don't stay at home at all, but they don't go out often, and the role of backpacks gradually decreases, so naturally there is no need to upgrade.

Because he didn't continue to upgrade, Su Yu naturally didn't know what special effects had been added to the level 7 backpack.

And apart from her, several other people have no idea of upgrading the backpack, so apart from rumors, there is no information about the level 7 backpack at all, and the game company itself has not released data in this regard.

The backpack was upgraded, and the copper balanced arrows were also made, and this time a total of fifty-five arrows were produced, which is not lucky, but it is not bad, it can only be said that it is average.

Because Doya was not in the territory, Su Yu put the arrow in his backpack and only gave it to her when he met Doya who had returned.

Su Yu's task for Lake today is to dig copper ore and marble, of which the copper ore is used by Su Yu to make arrows and upgrade backpacks, and the rest of her has other uses, so it is temporarily stored in the warehouse.

As for marble, she needed this for the construction of the building...... She needs to reinforce all infrastructure in her realm before the Dark Creatures attack.

The first Dark Attack isn't just about making the game more difficult, once the province has successfully survived the first Dark Attack (whether it's the 10th or 15th day), the province will gain a lot of reputation (and reputation for successfully defending against the Dark Attack), and you can choose whether to open the territory or not.

As Yun Li mentioned when he first came here, this is what the Sunset Territory is not 'open to the outside world'.

The difference between an open territory and a non-open territory is somewhat similar to the difference between a 'open' and 'non-open' stores.

When a territory is opened, the number of visiting travelers/wanderers increases, the number of visiting caravans or merchants increases, and the population grows faster.

Su Yu needs to build several buildings that must be in a territory before the dark creatures attack, so that as long as those travelers or merchant caravans come to the territory and live happily here, it will increase some prestige.

After they leave, the more satisfied they are, the more prestige they will gain, and there will be 'word of mouth'.

Under their propaganda, more people will come to the territory...... Take this as a virtuous cycle.

The 'must-have' buildings that Su Yu refers to here can be summed up as 'clothing, food, housing and transportation'.

In order, the first is 'clothing', and in this regard, Su Yu already has a sewing shop here, and Dolly has successfully upgraded her sewing skills.

Although the skill level is only beginner and you can't craft too many powerful things, you can still craft items such as clothes and bedding for everyday items.

The second is 'food', that is, where food is sold.

As for the food, Suyu now has a tavern and a serious and enthusiastic boss and cook, so there is no need to worry too much.

The only possible problem is that the food is a bit too monotonous, because the ingredients are limited to meat and berries, so the recipes of the territory are not rich.

However, Su Yu has already planted wheat and rice, as well as potatoes and corn, and Yousen is here, and when this batch of crops is harvested, the recipes of the territory will be expanded.

Like what bread, corn pancakes, rice, pancakes, baked potatoes, hash browns, baked corn...... It's just a matter of time.

Then there's 'live'.

Regarding dwelling, the buildings associated with it are nothing more than residential houses and post houses, both of which are habitable buildings.

Living is actually more important than the first two, after all, when others come to the territory, they can't let people shop on the ground, right?

In order to give them a place to live, Su Yu built a station in front of Warehouse 1 with the post card she had obtained earlier, and at the same time, she also planned to build another row of houses in the same row as the training ground, bringing the number of houses to ten.

Because wood has other uses, this matter is just a plan, and Su Yu just used the construction card to build a post station for free.

A post house can accommodate many people, a residential house can only live two people, and after a post station, unless there is a caravan like a cloud fence to stay overnight, otherwise the living space is sufficient.

Residential houses are generally for the residents of the territory, such as outsiders are mostly living in the post station, and there are not no people who want to live in residential houses, and it is not impossible, as long as you add money.

The last 'line' here actually refers to the road, but also to the means of transportation such as horse-drawn carts and donkey carts.

The road is already being built, not only in the territory, but also outside the territory.

As for things like horse-drawn carts and donkey carts, the building is a 'mount shop', but it's useless to have only a shop because there are no 'goods' for sale.

And horses and donkeys need to be bought by caravans that specialize in selling animals, and Su Yu has only come here with a caravan, so don't expect to meet a second caravan in a short time, not to mention that even if there is a caravan, it is not necessarily a caravan that sells animals, so the preparation for 'line' only needs to repair the road.

……

After solving the problem of food, clothing, housing and transportation, Su Yu turned out some other common commodities from the building list-

For example, there are 'tool shops' that sell tools such as axes, shovels, pickaxes, and fishing rods, 'weapon shops' that sell various types of weapons, and 'armor shops' that sell various types of armor......
