It's just a few more attempts, Xia Duo's mentality is very calm, of course, even so, he started the second spell casting as much as possible on the basis of the auxiliary node of the first spell casting.

Soon, the second spellcasting was completed, and Shado re-checked the physical stability of the attached mage tower, and it did not appear the worst, but it was not the best.

The physical properties have been stabilized a lot, but there is still some distance to be completely stabilized.

"Come again!"

Next, Xia Duo did not rest, and continued to cast spells. Nearly ten minutes passed, and the third spell casting was completed quickly. This time, the situation was a little bad.

The originally normal-looking tower of the attached mage tower has been distorted by the naked eye, and its color has changed from pure azure at the beginning to different shades.

Xia Duo hardly needs to do any additional inspections. It can be judged that this mage tower is scrapped only by the naked eye, and there must be uneven material inside it.

Of course, it's not impossible to do it all at once, but since the cost is only half an hour for him to cast the spell, it's better to start over!

However, before restarting, Xia Duo thought about it carefully. He believed that the transformation process was repeated several times by casting spells. There must be slight differences between each spell casting.

"Maybe it should come like this!"

Next, instead of continuing to cast spells on the basis of the original spellcasting node, Shado began to re-mark the spellcasting node, and he was going to try a double deduction spellcasting.

In layman's terms, a spell is only cast once, but the same effect will appear twice, and you can choose to make the two effects appear superimposed, or appear one after the other.

Some spell effects are suitable for stacking, while others are not. For example, most of the creation spells, if stacking occurs, there will be abnormal energy interference, so they are more suitable for appearing one after another, such as renju fireball.

If you want it to stack properly, the spell itself needs to be redesigned into a new spell similar to a super large fireball.

However, the spells of the transformation system are very suitable for superposition. Shado even believes that any transformation spell, after multiple stacking, may obtain a similar constant permanent effect.

Of course, constancy is not achieved in this way, constancy is achieved through element circulation.

The constant effect can be removed, but if it is a permanent effect, it is difficult to remove, which means that the essence has changed.

Xia Duo has a clear idea of ​​what he thinks, but it is not so easy to do in practice. He is not fully sure of the double interpretation of such a complex spell for the first time.

However, one thing about magic is very good, that is, the process and the result are basically a one-to-one relationship. As long as the spell design stage is not wrong, and the spellcasting ability passes the test, the final result will not be much worse.

Xia Duo is in such a situation at this time. Although he is not completely sure, the difference lies in the uncertainty of the spell casting process. In terms of spell design alone, he is quite sure.

In the future, some large-scale construction machinery may be designed to avoid interference caused by human factors, but now, it can only be built by hand.

…

After a while, the new spellcasting node was marked. Xia Duo took a break and put away the abandoned Mage Tower not far away, so as not to be an eyesore.

After everything was ready, Xia Duo began to double-spell the spell. It took nearly ten minutes to fully cast the original spell, but the double-spell did not bring about the superposition of time. It only took a minute or two longer than the original spell.

Soon, the spell was completed, and a mage tower identical to the elongated pyramid-shaped attached mage tower that appeared at the beginning appeared in front of Shado again.

Xia Duo checked the physical stability of the mage tower and found that the effect was better than the two repeated transformations just now. Although there is still some distance from the complete stability, it is not impossible to wait.

Even if it is a triple or quadruple interpretation, it is impossible to completely stabilize the physical properties of the mage tower immediately. It always takes some time. The difference is only the amount of time.

Maybe after performing the fourth and fifth layers, the physical properties will be completely stabilized in a minute or two, but now it is not that much different. Xia Duo roughly estimated that it will take about an hour, and he can still wait for this time.

…

Of course, in the process of waiting for the Mage Tower's physical properties to be completely stabilized, Xia Duo was not idle. After bringing the Mage Tower to the inside of the floating city that had been drained, he began to prepare to pour mithril.

Generally speaking, in the normal construction process of the mage tower, the tower body is built first, and then the mithril components are made according to the actual required functions.

[In other words, the best app for reading aloud and listening to books at present, Mimi Read, install the latest version. 】

If we go further, some mithril components will be laid out in advance during the construction process. Of course, if there is no accident, this part will basically not be maintained in the future. This requires the use of high-purity mithril materials to reduce the occurrence of The rate of elemental transmutation reactions. UU reading www. uukanshu.com

The other mithril components are more like attached to the tower body, and are only packaged with simple materials, which is convenient for frequent maintenance in the future.

Like the Tower of Time, there are even a lot of mithril components in the area where the element pool is located, and they are not even packaged. They are worried that the packaging material will react with mithril.

Areas like this have absolute authority restrictions. Except for a very small number of trusted people, let alone outsiders, it is basically impossible to even see related images.

Of course, the main features of the tower attached to the floating city built by Xia Duo are the single function, low cost and simple construction.

Among them, the construction is simple, not only reflected in the fact that the tower body is completely transformed from pure water, but also reflected in the production of mithril components, using the pouring method.

That is to say, the location of the Mithril component was reserved at the beginning of the design, which was the inspiration left by Shado when he made the spell chip on the projection plane.

It's just that the mithril used in the spell chip is extremely pure, and the mage tower only needs to use standard mithril. In Shado's design, this attached mage tower does not require maintenance, and maintenance is replacement.

After all, the function is single, the construction is simple, and the cost is low. If it is maintained, it may catch up with the construction cost after a few times.

However, although the attached mage tower he built this time has all the functions in the design, it also needs it to act as a normal mage tower before the main body of the floating city is completed.

Then you need to consider how often it is used, its intensity, and ultimately its service life.

In short, it is necessary for Shado to use mithril materials of better purity to delay the scrapping time of this mage tower after it has been used frequently or even with high intensity.
