"Lady Hildalana, just now you said that the biggest disadvantage of inspiration potions is that they are expensive, and now I feel very much in agreement with you!"

Xia Duo was about to bargain, but he didn't want Hildalana to give him a chance at all, so he directly interrupted him, "Then does Lord Xia Duo want it or not?"

"You must know that even if this potion is in Yeerlan, it doesn't mean that it can be sold with money, and without a certain identity, you may not even see the shadow of the potion."

"Yes."

Xia Duo didn't hesitate much, for him, the problem that could be solved with money was not a problem, the only thing to worry about was the authenticity of the potion.

"So how do we trade?"

"You probably won't want to let you come to Yerlan, so how about leaving it in Everesca?"

"Everisca?"

Xia Duo thought about it for a while, and finally agreed, and then he and Hildalanna agreed on the time of the transaction and the contact information, and then the communication was interrupted.

As for lobbying the Seven Towers, from the moment he was interested in the inspiration potion, even if he agreed, it was nothing more than a trip to Severynton in his spare time and a casual chat with those from the Seven Towers.

As for how many? How many words to talk about depends on Xia Duo's mood, anyway, he only agreed to lobby, but he did not guarantee what kind of effect it must have.

……

After leaving the communication room, Xia Duo temporarily put the transaction behind him, and the original plan for the afternoon was to go to the Azurite plane, and he hadn't forgotten it!

However, before going to the Azurite plane, he summoned Cecily to prepare 150,000 gold coins for backup, and after the message, he immediately walked into the portal, so as not to have a clean ear.

……

Azurite plane.

It's only been a few days since Xia Duo last came over, and the [Mithera] device has been working for more than ten days without any problems, but this time he didn't go to check.

Instead, he came to the main body of the floating city on the water side, and the last time he checked the physical stability of the main body, he came to the conclusion that it would not affect the subsequent construction for no more than ten days.

After checking again today, Xia Duo found that his previous judgment was still a little conservative, in fact, even if he started building the flight control system immediately, it would not have any impact.

However, the purpose of Xia Duo's visit today is not to build the flight control system, but to make some preliminary preparations for the construction of the flight control system.

The main point is to drain the water inside the main body of the floating castle, although it can be built with water, but it will have some impact.

Although Xia Duo had planned to build a floating city on the Azurite Plane before, he intentionally or unintentionally ignored the special environment of the Azurite Plane itself.

One side is full of water, and the other side is weakly eroded by negative energy.

If he had a choice, he would definitely choose the main plane, but unfortunately he didn't.

……

As for how to drain the water, it's very simple, but the process is not cumbersome.

Xia Duo simply turned around the interior, and came to one of the six main passages of the Floating City, since it was the main passage, the size was definitely not so small, and the entrance of the passage was almost a square with a side length of 100 meters.

If it is in the main plane, considering the existence of gravity, the force required to block the huge amount of water outside the floating city will be very large.

But in the aquamarine plane, gravity does not exist, and a simple single layer of waterproof enchantment is enough, of course, then again, if it is in the main plane, Xia Duo will definitely not choose to build it in the water.

A 10,000-square-meter giant enchantment would not be difficult even for ordinary mages, because the repulsive force generated by the unit area of this layer of enchantment is extremely small.

Of course, considering that there may be people coming and going in the future, which may bring some undercurrents to impact the enchantment, Xia Duo set the enchantment a little thicker.

The so-called "enchantment" is essentially a field, which is three-dimensional, not just a thin film, in fact, if he can, Xia Duo prefers to fill this repulsive field with all the gaps in the floating city.

It's just that such a large-scale constant field spell can't be designed in a short period of time!

Anyway, there is no gravity effect, just a simple plug exit.

……

Soon, Xia Duo completed the sealing of 6 main channels, 36 secondary channels, and hundreds of functional pores.

Then there's drainage, which makes it easier.

In the flight control system of the floating city designed by Xia Duo, there is an artificial gravity part, and now this part is just reversed to create a temporary sphere center convergence gradient gravity field.

After that, open a water element channel in the center, which is the lowest end of the gravity field, and drain the water away.

Now that the physical properties of the main body of the Floating City have been completely stabilized, Xia Duo does not have to worry about casting spells affecting its nature, so he can do it boldly with confidence.

There was no accident in the process of casting the spell, but the moment the spell was completed, Xia Duo immediately felt the almost endless force desperately squeezing his body, and for a moment, he almost thought he was going to die.

The surface consciousness may be negligent, but the subconscious mind will not, and almost at the moment when Xia Duo felt the pressure, his form turned into a stream of water, merging with the surrounding water bodies.

The pressure is gone.

"It's dangerous! Almost played yourself to death! Even if he was already in a safe situation, Xia Duo still had palpitations.

Although he has a pre-teleportation spell such as the [Teleportation Mark] on his body, you must know that this is in the Azurite plane, and the pre-teleportation spell on the main plane will not take effect here!

It would be a big joke to die here!

After adjusting his mood slightly, Xia Duo seized the time to summon the water element channel, the artificial gravity in the flight control system is not constant, it can only be regarded as eternal.

And the gravitational field that he obtained by casting the spell to converge towards the center of the ball lasts for a shorter time, so you must hurry!

In the form of water flow, Xia Duo does not need to cast spells to summon the water elemental channel, in an environment with such a large amount of water, he can summon the water elemental channel with the instinct of the bloodline alone.

And that's exactly what happened.

With the call of the bloodline, a swirling vortex appeared in the center of the floating city, where the main energy center [Mithera] device in the design was located.

Generally speaking, when the elemental channel is opened, a large number of elements are poured from the elemental plane to the material plane, but the reverse is also true.

In particular, the water bodies on the water side of the Azurite plane are almost all pure water, the simplest embodiment of the water element, and the simplest in reversing the past.

Elemental passages do not pass through matter, at least as Chado understands that elemental passages cannot pass through matter, but only through elements.

What he is doing now is to convert the pure water inside the Floating City into water elementals, and then discharge them to the water elemental plane.

Of course, if there is a water elemental derivative plane close to the material plane, it may be possible to drain water directly, but that is not something that can be solved by a simple elemental channel.
