Upgrading the city is not something that can be done casually, the first thing to do is to find someone who understands the overall planning, so after making this decision, Rocky immediately contacted the technician union, and then hired a group of designers, all of whom are experts in this field.

To do this, he spent a million gold coins, and this was only the money for hiring a technician.

From this point alone, you can see how much investment is required to upgrade a city, in fact, don't look at the current Sky City so much, but most of them will never have the opportunity to upgrade, because the cost of upgrading is too huge, the investment of tens of millions of gold coins is just offline, and the upper limit is simply not capped.

That is to say, even if Rocky has fifteen million gold coins as a capital this time, he may not be able to guarantee that he will be able to completely upgrade Thunder Eagle City, but as he himself said, now that he has the ability to make money, even if fifteen million gold coins are spent, he will be able to complete the city upgrade by relying on his own income.

So Rocky didn't save any money in this matter, and hired a technician for a million gold coins, as long as the technician could arrive immediately.

In any world, money can make ghosts grind, and after taking out a million commissions, the Technician Alliance, which was far away in Sleepless God City, immediately sent the technician over, and it took less than a week to arrive in Thunder Eagle City.

And these technicians immediately showed their professionalism when they arrived in Thunderhawk City, on the one hand, they sent people to inspect the entire city, and on the other hand, they found Rocky and asked him about his specific requirements for upgrading the city.

"Lord Rocky City, do you plan to upgrade the city directly to a large sky city, or a medium-sized sky city?"

The one who came to see Rocky was an old man, seventy or eighty years old, no matter in terms of appearance or temperament, he was no different from an ordinary old man, but Rocky did not dare to slack off in the slightest, this old man's name was Wene, a master in the field of urban construction, the reason why Rocky spent a whole million gold coins to invite this group of technicians, and a considerable part of the money was actually the cost of inviting Wene.

"Medium-sized Sky City. ”

In the face of Winn's question, Rocky answered truthfully, he didn't plan to let Thunder Eagle City do it in one step, firstly, it was unnecessary, and secondly, he did not have so much money and time.

This answer made Wynn nod and continue to ask:

"Do you have any plans to continue to upgrade in the future?"

"Yes, it will be upgraded to a large sky city in the future. ”

"Well, I know, then Lord Castle, what size do you plan to expand the city area to, and how many residents do you plan to accommodate?"

"Does it make a difference?"

Since it was the first time to upgrade the city, Rocky didn't know much about the process and steps of upgrading Sky City.

"Yes. ”

Regarding this problem, Winn directly explained: "Now the urban area of Thunder Eagle City can accommodate five thousand residents, if the Rocky City Lord wants to be more convenient, I can directly expand it tenfold, and expand the urban area to the limit of enough to accommodate fifty thousand people, so that a lot of engineering can be saved in upgrading the large Sky City, but the time and cost of doing so will also be higher." ”

"Of course, if the lord of Rocky City doesn't feel the need to expand so much, or wants to save some time, I can also reduce the size of the city somewhat, for example, only expand the size of the city to enough to accommodate 30,000 or even 20,000 people, so that it will save a lot in terms of cost regardless of the time and time, but once the city's population exceeds the upper limit, it will have to be upgraded again. ”

"I see. ”

After Winn's explanation, Rocky understood what he meant, and after thinking about it, he said, "Then let's just upgrade to the maximum." ”

"You mean, upgrade to a size that's big enough for a population of fifty thousand?"

"That's right. ”

Nodding, Rocky said affirmatively.

Upgrading Sky City requires a lot of time and a huge amount of gold coins, and it must not be done often, so it is better to do it in one step, although it is indeed a bit too big for the current Thunder Eagle City to directly expand the city by ten times, but it will definitely be used in the future, which Rocky is not honestly sure, so it is better to do it in one step.

And when he said so, Wen En naturally had no reason to refuse, so he then asked, "In addition to the city area, does the city lord need to build other new areas?"

"Yes, I would like to be able to build the barracks and research institute separately outside the city, and also expand the size of the airport, no, just build a new airport to park the fleet. ”

"You mean to build a separate military port, right?"

"That's right! ”

"No problem, is there anything else that is needed, like expanding the whole area of the city, adding some new farmland, etc. ”

"This ...... Probably not. ”

Nodding, Winn jotted down Rocky's requests, asked Rocky a few more questions, and left, but within a few days, a week to be exact, he met Rocky again.

During the week, the team brought by Wynn had already inspected the entire Thunderhawk City, and after the inspection, they had made a new design and plan for the city, and the meeting between Winn and Lodge was just for him to see the planned plan for himself.

Of course, this is only a preliminary plan, it can also be said that it is just a general direction of the upgrade, as long as Rocky agrees to this plan, then Winn and the team will plan in detail according to this general direction, and finally complete the entire upgrade plan.

"Yes. ”

After a general look at the plan, Rocky said that although the detailed plan has not yet come out, all the requirements he has put forward before have been reflected in this plan, which naturally makes him satisfied.

However, after that, Rocky made a new request: "Master Winn, do you need to replace the Super Crystal to upgrade the city?"

"Yes, it has to be replaced. ”

Winn nodded affirmatively, the super crystal is the core of Sky City, so it must be replaced when upgrading, because the super crystal used in the small Sky City cannot withstand the medium-sized Sky City.

"What level of crystal do you plan to replace?"

"Medium-sized Super Crystals, of course. ”

Rocky's question made Winn a little confused, since Thunder Eagle City is going to be upgraded to a medium-sized Sky City, it is naturally going to be replaced with a medium-sized super crystal, is it possible that you can still use a high-grade super crystal? That can only be used in a large Sky City.

"I want large crystals. ”

Just when Winn was puzzled, Rocky blurted out that he hoped that the super crystal of Thunder Eagle City would be directly replaced with a large crystal during this upgrade!

"Lord Rocky, why?"

"I have my own plans. ”

Faced with Winn's puzzlement, Rocky replied mysteriously.
