The discovery of the Moving Castle is of course of great significance to Rocky, because he has a back mountain village, so any technology or weapon that can play a role on the ground is of great use to him, but this is not the case for Karina, and the Moving Castle is not of much practical use to her.

So her idea was simple, that is, even if she handed over the mobile fortress and design materials to Rocky, as long as Rocky could come up with enough benefits in exchange, and the ideal solution in her mind was to exchange the mobile fortress for the technology related to the White Demon Warframe!

It's a pity that as soon as she finished saying this, Rocky shook his head: "No, no, the mobile fortress is too different from what I studied, and it is not so valuable." ”

This is not Rocky's perfunctory, but the real truth.

The Mobile Fortress is good, really good, but it's just good, but what about the runes he has mastered? That's great!

Exchanging what can only be called a good mobile fortress for a rune that is a great invention is not an equivalent exchange.

After that, Rocky proposed another plan, but it was unsurprisingly vetoed by Karina, followed by Karina also put forward her own idea, and Rocky shook his head, and the two discussed back and forth for a long time.

Some people may ask, what are the two of them doing, are they okay to tease the shell?

Of course not, the two of them put forward conditions back and forth, it seems that there is no meaning, as if they have never been negotiated, but in fact it is of great significance, they are testing each other's bottom line!

As mentioned earlier, this negotiation is not a negotiation in the traditional sense, because it involves the interests of both parties and the relationship between them.

If it was just a negotiation in the ordinary sense, they could come up and put forward their own demands, and then pull each other apart, even if they tear their faces in order to finally negotiate.

But Rocky and Karina are reluctant to let things turn out like this, they have known each other for several years, and they have worked together many times in the past few years, and even experienced several life-and-death battles together, so the two may not have signed an agreement on paper to become allies, but their relationship with each other has long reached the level of allies.

In the sky where there is constant war, they know very well how hard-won this relationship is, so no one wants to destroy this relationship for the sake of profit.

However, their status requires them to fight for more, not only for themselves, but for all those under their rule.

So how to find a balance between the relationship and interests, so that this negotiation becomes a new starting point for them to trust each other more, rather than the end point of their mutual break, has become the key.

So after the temptation of talking and laughing as if chatting, the two finally reached an exchange agreement.

First of all, the mobile fortress belongs to Rocky, because he obviously needs this fortress that can fight immediately as long as it is full of magic energy, and in exchange, Rocky will make a set of battle armor for Karina for free, that is, the white demon battle armor! But since the technology of the white demon armor has not yet been announced, Karina must keep a tight mouth about everything related to it after getting the white demon, even in the face of Berg, otherwise he didn't say what would happen to Rocky, but presumably Karina could guess it.

Secondly, all the research materials about the mobile fortress are shared by both parties, that is to say, two people have one copy each, and as for how they use it, whether they start manufacturing it themselves or sell it, the other party cannot ask about it.

Finally, Karina wants to sign an order with Rocky, and after the Thunderhawk City Arsenal makes the first batch of airfight armors, she will buy fifty new armors, and of course Rocky will sell them to her at a lower price than the market price.

After determining these three points, the two of them got a satisfactory result in this 'spoils', Rocky got the mobile fortress, and Karina got the coveted white devil armor, and at the same time, the research information about the mobile fortress was one for each party, and no one interfered with the other.

As for the last one, it doesn't really have much to do with the matter of moving the fortress, but it involves the matter of warframe manufacturing.

Now the Apple Tree Chamber of Commerce is in full swing to build an arsenal in Thunder Eagle City, and when the arsenal is completed, it will naturally start to manufacture battle armor, although the Apple Tree Chamber of Commerce promises to ensure sales channels, and they will indeed spare no effort to develop channels, but Rocky can't hand over all this kind of thing to the other party, it's not that he doesn't believe in the ability of the Apple Tree Chamber of Commerce, but he doesn't want to put all such an important lifeline in the hands of the other party, and he must also expand his own sales channels.

In this way, if the cooperation with the Apple Tree Chamber of Commerce is always good, then it is a win-win, but if the two sides break up, Rocky will not have no way out.

Therefore, after discussing the matter of the mobile fortress with Karina, Rocky introduced her to the special battleframe for air combat, and Karina was naturally very interested in this matter, plus Rocky was sure to sell the battleframe to her at a discounted price, so the two sides hit it off and immediately signed an agreement.

And when all this was settled, Rocky finally had some free time, but although he was idle, the others were still very busy.

A big battle in the ruins of Cassin City, although the mobile fortress was rediscovered, but the guards also suffered heavy casualties in the battle, after returning to Thunder Eagle City, after statistics, the guards killed more than 80 soldiers, and more than 30 people completely lost their combat ability, that is to say, after this battle, the reduction of the guards was more than one-fifth.

It stands to reason that such casualties are normal, because it was a battle against hundreds of demons! In such a battle, not only were the guards not wiped out, but the casualties were only one-fifth, which could have been celebrated directly by other troops!

But this is not the case for the Guards, because the casualties in this battle were the largest of all the battles in which the Guards participated, so when everyone returned to Thunderhawk City, the arrangements for the aftermath of the dead soldiers, as well as the war pensions and other issues had to be dealt with, and at the same time, due to the large number of attrition, the recruitment of new recruits had to be carried out.

On the other hand, the research of the mobile fortress by Aniye and others continued, and after just a few days of research, they found Lodge and began to discuss something more important with him.
