"Haha, that's really the case! When there are three markets, the exchange difference is immediately reduced by half, yes, keep coming!" The next day, after building a market in the castle in the mind of that subordinate, Ye Yifan was also pleased to see the result he wanted, that is, the difference between exchanging crystal energy for various resources in the market was reduced again, and only the initial half was left.

At this time, Ye Yifan immediately created five castle prototypes, and for each castle prototype he made, he would hand it over to one of his subordinates, and asked the other party to build a market as soon as the castle was built.

By the time the fourth market was completed, Ye Yifan found that the crystal energy needed to exchange resources was only two-fifths of the original one.

After the fifth market is built, only one-third of the crystals required to exchange resources will be used.

After the sixth market was built, only a quarter of the crystals needed to exchange resources were consumed.

However, the sixth market is also the limit, at this time, Ye Yifan's exchange ratio when exchanging crystal energy for ordinary resources such as star wood and star stone is 625:1, and the exchange ratio when exchanging rare resources such as star mother mercury, star core crystal, moon shadow sulfur, and solar gem is 1250:1.

After that, no matter how many markets Ye Yifan has under his name, this exchange price will not be lowered again.

But even so, the resources consumed by Ye Yifan when he continued to build the original castle body were greatly reduced, and the same was true when he was building various buildings in the New City Global Village.

Only seven days have passed since the completion of the village hall in the new city global village, and Ye Yifan has completed the construction of most of the buildings in the new city.

"It's not bad, the soldiers produced by the various types of military buildings in the global village are all embodied soldiers, although the price is ten times that of the unembodied soldiers, it is equivalent to one more soldier, and the number of soldiers produced by it is ten thousand times that of the unembodied castle. At the same time, it has also been blessed by special buildings such as Elas's sentinels, which is really good!"

In addition to the large number of soldiers produced in it, it is more important because the new city is very well defended and large enough in case of danger. It is completely possible to temporarily evacuate the people of the earth's civilization here.

Since it exists in the form of a castle, the power of the hidden star in the global village can also be weakened to varying degrees, especially in the residential areas, where the existence of the hidden star power is almost not felt. In this case, if the people of the earth enter the global village, they can definitely live forever without worrying about being attacked by the power of the hidden star.

Of course, a castle can't accommodate more than 100 trillion people on the earth, but don't forget that Ye Yifan can also continue to build castles. Although the cost of building each castle in the hidden space is quite amazing, with Ye Yifan's current crystal energy income, he can still easily build many of them, as long as he is given a little time, even if he fills the corresponding hidden space of the galaxy!

"Well, by the way, can't I still build a castle on those traffic arteries? Why didn't I think of it before? No, I have to implement this plan quickly!" Thinking of this, Ye Yifan immediately made arrangements. He called two of his men who had already built the castle in his mind, and each made a castle prototype. Give it to them, and transfer a lot of resources to the castle in the minds of these two people, let them go to the transportation route near the earth to build the castle, and try to build the castle before the arrival of the Zeg army, so that they don't have to fear the attack of the Zeg tribe!

In the case of having a castle as a defense to rely on, it can be said that it has many advantages. One of the biggest is that enemy ranged attacks are weakened, leaving only about half of their power. In addition, the towers in the castle will automatically attack all enemies that come within its attack range, and will only attack the ranged attack units in them. Therefore, if you have a castle, the gap between the two sides will be closed in an instant, even if the Zeg army is several times more than your own soldiers. It is also possible to win the battle!

In short, the castle is like the ancient border fortress, the auxiliary role is great, once owned, as long as there is not an internal problem or the disparity between the enemy and our forces is too great, it will generally not be breached. As for the situation of food and water shortages or internal moles like the ancient border fortresses, it is completely impossible to exist in the hidden space, and it is a big deal to tear up the hidden space and occupy a planet outside to plant, you can get the materials for everyone's use, presumably in the real space corresponding to a castle that covers a wide area, you can still easily find this kind of planet!

......

As time passed, the Zeg army seemed to have completely forgotten that there was such an unconquered star field as the Earth civilization behind them, and never sent any more soldiers.

In this regard, Ye Yifan did not show the slightest impatience, he just arranged for his heroes to build eight castles in this hidden space one after another, of which the one Ye Yifan originally built is needless to say, located in the hidden space corresponding to the central region of the galaxy, and the other four are located near the hidden space star gate corresponding to the four cantilever arms, two are located in the area near the corresponding hidden space on the earth, blocking the front and back roads, and the last one is towards the area where several Zeg armies have appeared one after another.

Needless to say, there are seven castles in front of you, and the location of each one has been carefully considered. As for the last one, it was Ye Yifan's arrangement, and he found that the Zege soldiers seemed to like to appear from there, which showed that the area must be relatively easy to break through, and according to inertia, it was very likely that the Zeg army would also appear from that area when they came.

......

On the seventeenth day after Ye Yifan built the miracle building of Elras's Sentinel, the Zeg clan once again sent troops to the Earth civilization.

This time, it was a well-deserved army that came to attack the Earth civilization.

"Buzz!"

Ye Yifan stood on the tall wall of the eighth castle, looking at the dense Zege soldiers not far away, and his heart couldn't help but tighten.

However, when he thought of the massive number of soldiers behind him, Ye Yifan felt emboldened. What's more, with the strong protection of the castle, he can definitely exert a pretty good damage weakening effect when facing the attack of the Zeg clan!

It is worth mentioning that at this time, there were not only Terran soldiers under Ye Yifan's command, but also a large number of Forest Clan and Academy Clan soldiers under Ye Yifan's command.

When relying on the castle for defense, the ranged attack class is tantamount to the main force of the battle.

Needless to say, the Terran soldiers have embodied the second-level soldier archer, the second-level elite soldier crossbower, the fifth-level soldier priest, and the fifth-level elite soldier Holy Inquisitor are all good at long-range strikes.

Among the foresters, there are even more ranged attack classes. Manifest Tier 1 Elite Soldier Elf, Evolve Tier 3 Soldier Hunter, Manifest Tier 3 Elite Soldier Hunter, Manifest Tier 4 Soldier Druid, Manifest Tier 4 Elite Soldier Druid.

Among them, the Forest Clan's Flower Demon, a fourth-level soldier Druid, and a fourth-level elite soldier, the Druid Elder have magical strike abilities, and their lethality is even more amazing. At the same time, the third-level soldier hunter and the third-level elite soldier hunter leader have the ability to shoot double, that is, shoot two arrows at the same time, and the lethality can be called terrifying.

But that's nothing, and the only truly powerful ranged attack unit is the academy soldiers.

Among the Academy, ranged attackers range from the lowest Tier 1 Soldier to the highest Tier 7 Soldier. The first-level Soldier Quib, the Tier 1 Elite Soldier Elite Spirit, the Tier 4 Soldier Mage, the Tier 4 Elite Soldier Archmage, and the Tier 7 Elite Soldier Titan.

It can be said that the academy clan is the main force of the long-range attack, especially the Titan, a seventh-level elite soldier who has manifested among them, is simply a turret, with them, Ye Yifan feels very stable in his heart!

Not to mention that there is still a killer feature of Ye Yifan hidden in the castle, that is, the unique eighth-level soldier! The eighth-level soldier battle griffin has been embodied and the eighth-level elite soldier colorful battle griffin has appeared, both of these soldiers have the ability to release the battle dive infinitely, and it can be said that they are completely invincible on the battlefield, only for their part of attacking, and the attack of the enemy soldiers can not find these griffons who are constantly fighting and diving!

"Come on, let me see how powerful you really are! After today, I will take the initiative to go out of the galaxy, enter the vast star field outside, build more castles, and take back the territory belonging to the human race little by little!" Seeing the Zeg soldiers constantly rushing towards this side, Ye Yifan suddenly became proud in his heart, and shouted violently!

At the same time, those Zeg troops are also silently and orderly gathering, every Zeg soldier climbing down the cliff will silently enter the queue, all Zeg soldiers can accurately and quickly find their position, the whole process is like an old-fashioned mechanical watch, no mistakes!

Seeing this orderly and well-disciplined army, Ye Yifan couldn't help but compare them with the embodied soldiers under his command, and finally found that there was almost no difference between the two sides. However, Ye Yifan believes that the soldiers under his command are led by heroes, and they will definitely be able to exert their unparalleled combat power, and they will definitely be able to defeat the incoming enemy, and even wipe out the tens of millions of Zege troops in front of him!

And the reason why Ye Yifan was so confident was because the area where the Zege clan army was located happened to be a dead place at this time, between the eighth castle and the cliff. Once the other party is defeated and retreats, it is impossible to successfully escape, and they can only watch as the soldiers under Ye Yifan's command rush up and encircle and exterminate it!

Of course, the premise of being able to do this is that Ye Yifan must lead his soldiers to defeat this Zege army! (To be continued......)
