Using the southwestern border of the Central Region to border with Dragon Valley, this method of mobilizing the masters of Chen Yang's army in the Xixuan Kingdom from Dragon Valley at any time can indeed make Chen Yang's strength skyrocket countless times in a short period of time, and even if there are other big forces attacking, Chen Yang is also a two-dimensional situation that can be attacked and retreated!

At this point, it is obvious that Chen Yang is satisfied!

But satisfaction is one thing, and wanting to do it is another thing, because, if he does this, Chen Yang will still face a lot of problems, for example, what to do after those are mobilized?

The Middle Domain is all sects, and it is not a city like the other four regions, so many soldiers, once they are mobilized, the problem of survival is a big deal!

Therefore, when he thought of this, Chen Yang's eyes looked at Donald again!

He believed that at this time, Donald should already have a solution in his heart!

Sure enough, Chen Yang's guess was not wrong, Tang Lao did have it, and the next moment, looking at Chen Yang's puzzled look, Tang Lao said: "If you follow this second plan, it is to build a city and build a city in the Central Region"!

"Building a city, isn't this a big deal, just with our current strength, if we want to build a city, it's very difficult, right?"

Chen Yang said in surprise!

This point, he didn't think of it, but if he wants to build a city, it's not a matter of one or two days, is it enough for these people to say by himself? At this point, Chen Yang has no bottom!

"Don't worry, if it were someone else, it might be difficult to build a city, but you, building a city, is very convenient" And Donald, after hearing what Chen Yang said, said with such a smile!

Even at this time, a pair of eyes were always on Chen Yang's body, which made Chen Yang have no bottom in his heart, and he didn't even know why Donald said that!

But it was only for a while, and soon, Chen Yang understood!

Because at this time, Donald directly smiled and said: "Stinky boy, have you forgotten that you have a complete internal world, where you are the master, and everything is very easy!"

When Old Tang said this, Chen Yang was stunned for a moment, and then said with a smile: "What do you mean by the old man, let me build a city in the inner world, and then move it directly outside, right?" ”！

Chen Yang is not a fool, Donald has said it so clearly, at this time, if he still doesn't know what to do, then he can't say it!

Therefore, when Donald said this, Chen Yang immediately responded!

"Yes, that's it"!

Donald nodded and said!

"If that's the case, maybe you can, but the materials still need to be found!"

Chen Yang pondered for a while, and soon, he determined, do what Tang Lao said, but this is one thing, materials, but another thing, the materials needed to build the city are massive, and Chen Yang has already determined that even if all the emperors on his Xixuan side are mobilized, at least, it is necessary to build three cities, and it is also the kind of big city that can accommodate nearly 10 million people, this is a very huge siege!

Even, Chen Yang didn't know if these materials were enough!

"Don't worry, as long as there is no problem on your side, I will deal with the matter here," Donald said with a smile!

After finishing speaking, he chatted with Chen Yang about some other things and left!

And Chen Yang stayed with Sister Hua and Zhu Lin in this Sword Gate for more than ten days, and after more than ten days, all the people returned to the Valley of Forgotten Worries!

After all, it was Chen Yang's base camp, and not long after Chen Yang returned to the Valley of Forgotten Worries, Tang Lao had already sent news that he had found the materials to build the city!

This made Chen Yang somewhat surprised, although the materials needed for the construction of this city cannot be said to be as strict as refining some weapons and warships, but some stones still require a lot!

But now, it has been less than a month for Donald to find it, how can this not surprise Chen Yang!

But even if it was an accident, Chen Yang still quickly went to see Donald!

"Really found it??" Looking at Donald, Chen Yang asked suspiciously!

"Old man, I can't lie to you, come with me" Tang Lao smiled and walked towards a death area on the east side of the Valley of Forgotten Sorrows, which according to Chen Yang's knowledge, should be a perennial terrifying thunder and lightning!

Seeing Donald walking towards the death area, Chen Yang was very puzzled, but he still quickly followed!

For three days in a row, Chen Yang followed Donald, and finally, three days later, Chen Yang and Donald arrived at the center of this death area together!

", this, this is thunder crystal, so many thunder crystal mountains?"!

At first, Chen Yang was still very confused, but when he saw the thing in front of him, he was shocked, and even lost his voice and shouted such a sentence!

Thunder crystal is a very strange stone between heaven and earth, this kind of stone, at the beginning, should be an ordinary stone, but because of the absorption of excessive thunder and lightning power, it has mutated!

After the mutation, the thunder crystal, in addition to being very hard, also has the ability to resist some attacks!

Under normal circumstances, this is used in the army to refine armor for soldiers!

But even if this is the case, refining armor in the army is only a little bit at most, and it will definitely not be too much! And at this time, in front of Chen Yang, this thunder crystal actually has so many mountain ranges, seeing this, even Chen Yang, this guy who has already seen a lot of treasures, is a little shocked!

A little thunder crystal is nothing, and even it is sold outside, but this mountain range is it, which makes Chen Yang surprised!

"That's right, how about it, if you use these thunder crystals to build a city, isn't it enough:"!

Donald smiled, nodded, and said to Chen Yang!

"Haha, enough, of course enough, so many thunder crystals, if it's not enough, it's a joke"!

Chen Yang said with a smile, the smile on his face was very thick!

"It's just that this thunder crystal is extremely strong, and if it is mined, it may be a little difficult"!

But soon, Donald said helplessly!

There is thunder crystal here, and Donald also discovered it by accident, and he was very happy after discovering it, but the thought of mining such a mountain made Donald a little unsure of what to do!

"Don't worry, I'll leave this matter to me, by the way, you give Huang Yu'er the dark iron we got last time, and let her start refining the battleship as soon as possible!"

Chen Yang smiled confidently, and said so, after saying this, before Tang Lao could react, what Chen Yang was going to do, Weng said, behind Chen Yang, a terrifying force erupted!

Thundered

The next moment, Donald found that the huge thunder crystal mountain range in front of him actually began to shake violently at this time, and even, about an hour later, it actually disappeared little by little!

"You, you've transferred this mountain range to your inner space, right!"

I didn't understand it just now, but seeing this, Tang Lao understood, and looked at Chen Yangdao with a shocked face!

"That's right, it's all transferred to my inner space"!

Chen Yang smiled and said!

Thunder Crystal is outside, it may be very strong, and even if it is a master of the emperor, it is very difficult to destroy it, but in the space of his own body, this is the same as building a city, it is very simple!

After all, in his own internal space, Chen Yang is the master there, and everything there has a huge relationship with Chen Yang!

It can even be said that as long as Chen Yang has a thought, it is very simple to change the structure of these thunder crystals!

At this time, Chen Yang will do this!

"Good boy, I know you have a lot of options, since that's the case, I don't need me here, I'll arrange other things"!

Donald laughed, said so, and after finishing speaking, he left!

And Chen Yang, after Donald left, also entered his own inner world!

There are three layers in the inner world, and at this time, in the first layer, in addition to the original peak plants, a huge thunder crystal mountain range is also among them!

"There is only a holy city in the Middle Domain, but this is the past, from now on, I, Chen Yang, will also let this Middle Domain have its own city"!

The next moment, Chen Yang muttered to himself, and then, his mind moved!
