The last item is a remnant of the old system, which is used to purchase various magic items from the members of the Tower of Time, and if this item disappears, the rest of the magic items in terms of income will also disappear as well.

In the past, the flow of funds from the Tower of Time was basically on this line, but now it has only been replaced by the sales revenue and salary expenses of mass-produced magic items.

"Shura Warrior God"

As for the maintenance fee, it belongs to the maintenance cost within the Tower of Time, although it has been rising steadily, it is also a relatively fixed silent cost, and Xia Duo did not include it in the overall income and expenditure items.

If you really want to calculate carefully, the production cost of mass-produced magic items can also be counted.

Here, Xia Duo only counts the relationship between the income and expenditure of the Tower of Time itself and the outside, and as for the interior itself, it is ignored for the time being.

After all, the Tower of Time has now entered a stable period after the transformation, and it is not appropriate to make too many changes internally.

In addition, the income from smuggling with Lord Collins was not taken into account by Xia Duo, after all, it had nothing to do with the Tower of Time itself.

Similar to the difference between personal funds and corporate funds.

And when he enumerated all the relationships on paper one by one, everything was very clear, and Xia Duo found that there was almost only one choice in front of him, and that was -

Increase the sales revenue of mass-produced magic items!

Currently, there are four types of magic items in the Tower of Time that have been mass-produced - the Communication Weapon, the Vigilance Charm (the name of the Charm is actually in the form of a statue), the Missile Wand, and the Demon Slaying Charm (True Charm and Premium Goods).

Among them, the Demon Slaying Talisman, although there are still sales after the end of the underground war, it is not a concept at all compared to before the end of the war.

In addition, the missile wand, although it has also been mass-produced, but because it is an offensive consumable, the actual sales are very unstable, and the total sales are not even as good as the warning talisman.

The Alert Amulet, on the other hand, is generally only purchased by non-caster adventurers, and sales have been getting weaker and weaker since its initial launch.

If you look at it over a long time, sooner or later you will be caught up by the missile wand.

What really supports the operation of the Tower of Time is actually the communication magic device, which is also a product that Xia Duo has the most high hopes for, and Nia even changed the original research direction for this reason.

It's just that the communication device is far from being saturated in the Nessera market today, which can also be seen from the fact that it can be sold as much as it produces every month.

If he could, Xia Duo really didn't want to mention any upgrades at this time.

But if you don't upgrade, how can you increase your income all at once?

It is possible to expand production, but on the one hand, the market is not yet saturated, and other mage tower organizations are also seizing the time to ship, once the tower of time expands production, it can indeed increase income in the short term, but in the long run, it is easy to be boycotted by other mage tower organizations.

The money has been made by the Tower of Time, what else do others earn?

On the one hand, the market is very large, and the high-end and low-end do not affect each other, on the other hand, this can be regarded as opening up a new high-end market for other mage tower organizations in advance.

In fact, what Xia Duo wants to do is to upgrade directly to the communication lock, so that it is not a hammer deal, and the follow-up various lock services are the bulk of the charge.

It's like now, even if the premium is high-end, if someone else buys it back, then the transaction will end here, and there is no need to give the Tower of Time even a copper in the future.

It's just that Nia's communication lock, and now I haven't even seen a single stroke of the eight characters, so I won't need it at all this time.

Xia Duo thought about it, and if he wanted to increase his income by normal means, he would probably have to launch a high-end communication device in advance.

Other mass-produced magic items, on the one hand, take time to mass-produce, and on the other hand, they are not as easy to cut as leeks as communication tools, which are a latent demand for almost everyone.

Of course, in addition, you can also make some extra money, such as engaging in some private customization of high-quality magic items, or increasing the smuggling of Comanso.

Even concealed his identity and quickly shot a batch of arcane energy crystals, but in the future, after [Mishera] was made public, others could lock their identities without guessing, and this kind of almost costless behavior of cutting leeks was really too disgraceful.

Xia Duo also dispelled this idea after just thinking about it, and shot high-grade Mithril, although he was also cutting leeks, but because of the limited current Mithril refining technology of Nesser, it was actually a collection of character!

However, this practice also has hidden dangers, which can easily attract the attention, vigilance, and hostility of the elves, and even direct investigation and intervention, especially the Yerlan Moonhorn family, which monopolizes most of the high-grade Mithril trade in Nesseril.

Xia Duo has reached a certain cooperation intention with Hildalana of the Moon Horn family, and if there are no special accidents, he is not prepared to overstimulate the other party.

Of course, in addition to the above money-making methods, Xia Duo can also choose to hug Iolem's thighs.

It's just that the money is good and the favor is hard to repay, and he will definitely ask Iolem for help, but it is certainly impossible to rely on the other party completely.

……

With this decision in place, Shado immediately returned to the Tower of Time, and after discussing it with Nia, it was not surprising that he received Nia's full support.

At the same time, this incident also stimulated Nia to complete the design of the communication lock as soon as possible, of course, before that, she had to complete the "promotion book" tailored for her by Xia Duo.

In front of the projection window of the study on the top floor, Nia immersed herself in her work, while Xia Duo began to revisit the details of the plan for the upgrade of the communication weapon from the perspective of a Grand Arcanist.

At that time, he wanted to refer to the penguin communication in his hometown, so that the function would be easier to implement and the upgrade could be followed.

But now, Xia Duo wants to take the upgrade route of his hometown mobile phone as a reference, from a big brother who can only make phone calls to a feature phone with simple functions, and then to a smart phone.

The main reason is that he found that if only communication is used as a selling point, even if there are upgrades in functions and experience, it is not so easy to sell at a high price.

The Color-resistant people have never used or heard of the communication software on the earth before, and the color-resistant people will not necessarily buy the communication upgrade alone.

And Xia Duo has little time to discipline consumers, so he must upgrade the communication method with the attitude of making mobile phones from scratch.

In addition to communication, there should be at least one new feature that will make color-resistant mages fall in love so that they are willing to pay a high price.

As for styling or something, it can only be regarded as an additional plus, not a core element.

As he thought about it deeply, a vague idea appeared in Xia Duo's mind, but it couldn't be completely formed for a while, so he simply picked out the communication function first and redesigned it with the current vision.
