Although the demons have occupied the land for a hundred years, people have not stopped after fleeing to the sky, in fact, the whole world has been developing and progressing in the past hundred years, and the steps are not small.

It's just that the sky is too vast and boundless, and the communication between the scattered Sky Cities is extremely unsmooth, coupled with the imbalance of manpower, material resources, financial resources, etc., resulting in the development of various Sky Cities is very uneven.

The mighty Sky City, a monster-level metropolis like the Ten Divine Cities, had already surpassed the top cities of the Land Era in its splendor and reached a new height that no one had imagined before.

In addition to the Ten Divine Cities, some large Sky Cities have also developed very rapidly, and these large Sky Cities may not be comparable to the Ten Divine Cities, but their scale surpasses the cities of the Land Era.

And some of the weaker Sky Cities, such as some large Sky Cities and most of the medium-sized Sky Cities, have at least recovered to the level of the Land Era, and there is no difference between the cities of the Land Era in all aspects.

As for the weakest group of cities in the sky, it is a small sky city like Thunder Eagle City, these small sky cities are more than an era different from other cities no matter how you analyze them!

Rocky didn't know this kind of thing before, because he had been staying in Thunder Eagle City since he crossed over, and although he knew that Thunder Eagle City was weak, because there was no horizontal comparison, he didn't know how weak Thunder Eagle City was and what level it was in the entire sky.

But after spending two days in Sleepless God City, especially after visiting the weapons market, Rocky realized how backward Thunderhawk City really was.

Why did he suddenly understand?

Because in any world, a weapon is a ruler, and this ruler can measure the strength and weakness of everyone.

As a simple example, in Thunderhawk City, Rocky is already the strongest person, after all, he is the only one who has the Air Demon Battle Armor, and there is only one set of Air Demon Battle Armor in the entire city, but in the Night God City, a small air patrol is equipped with the Air Demon Battle Armor!

The strength or weakness of the two cities is judged by this matter alone.

Being able to equip a small inspector with an Air Demon Battle Armor is enough to show how strong the economic strength of the Nightless God City is, and it is also enough to prove how strong the military strength of the Nightless God City is, and the dual strength of the economy and the military also represents how important the position of the Nightless God City is among all the Sky Cities.

That's all the weight of the weapon.

Therefore, after visiting the weapon market, especially after seeing the latest Air Demon Warframe, Rocky basically knew what level Thunder Eagle City was in the current world, and at the same time had a more comprehensive understanding of the Air Demon Warframe.

Although Rocky also has a set of air demon battle armor, his battle armor is too old, and after shopping around the weapon market, he learned that his air magic battle armor belongs to the first generation of warships, but the latest air magic battle armor is already the fifth generation!

This disparity is no small blow to Rocky.

Therefore, for several days after that, he did not continue to wander around, but buried himself in the library of the Sleepless God City.

I have to say that after coming to the Nightless God City, Rocky's insight has skyrocketed, and his future direction and goals have gradually become clear, in this case, just using the magic runes to strengthen weapons and equipment is no longer enough to satisfy him, he intends to use the magic runes in more places, and maximize the value of the runes.

This idea naturally requires a lot of knowledge to be realized, so Rocky went out early and returned late for the next few days, spending all his time in the library.

In this way, three days passed in a flash, during which Lilia had already found a chamber of commerce willing to trade with Thunderhawk City, and all aspects had been negotiated, which meant that they could actually leave a long time ago, and the reason why they remained in Sleepless God City was entirely due to Rocky.

Because since he started to soak in the library, Rocky has become out of control, and the whole person has completely drowned in the ocean of knowledge, so that he has been dragging in the city of Sleepless God for many days.

And today, it was the last time Rocky came to the library, because Erin had given him an ultimatum, and they had already spent more than five hundred gold coins just on food and accommodation in the City of Sleepless God, plus the entry tax to be paid when leaving, the expenses had already exceeded a thousand, which greatly exceeded Erin's previous expectations, and they had to leave.

In this case, Rocky had to hurry up and find all the books he needed in the library, and then buy them all in one go, preparing to study slowly after returning to Thunderhawk City.

"This book is also useful......"

After flipping through a few pages of a book called "Principles of Magic Cannon Construction", Rocky handed it to Lilia, intending to buy it later.

But at this time, a young woman happened to pass by him, Rocky was nothing, his attention was on the book, but the woman then turned her head to look at him, and after reading for a while, she couldn't help but speak:

"Rocky, is that you?"

"Huh?"

Hearing someone call him, Rocky stopped, then looked back, just in time to see the woman looking at him.

Looking at the young woman who called her name, Rocky looked strange: "Are you calling me?"

Pointing to himself, Rocky asked uncertainly, because he didn't know each other at all.

"Rocky, you don't know me anymore?"

At this time, the young woman had already walked up to him and looked at him, the expression on her face was a little indescribable.

"Do I know you?"

The other party's words made Rocky look at the woman more closely, and he found that this woman was very beautiful and very well-dressed, giving people the feeling that she had a bit of similarity with Erin, obviously she should be a nobleman.

But he really didn't know this man!

Seeing that Rocky didn't recognize herself for a long time, the woman's expression became even more strange, but finally she said: "Rocky, my name is Cyryl, we met in Myront City a year ago......"

"Morient City ......"

Hearing this name, Rocky suddenly felt a little impressed, and then suddenly remembered that his father's family was not the Myronte family!

Thinking of this, Rocky suddenly remembered who the woman in front of him was, and then let out an exclamation: "Cousin?!"
