Little Lord's Dark Castle

More than 4 quarries were smashed down, and the scope of the territory was finally expanded to the limit. Next, before the territory was promoted to four stars, there was only one last promotion condition left, and the alien beasts in the territory were cleaned up.

With a territory of ten kilometers, this is quite a wide area.

Thanks to Chu Xin who had done a lot of preparatory work before, the hunting team in the territory cleaned up day and night, and cleaned out the more troublesome black gorse and ground fire ants, and the rest were not dangerous.

After the territory is expanded, all targets that do not belong to the territory are clearly displayed on the territory map.

Chu Xin commanded the grass regiment and a group of troops in the territory, and began to gradually clean up in four directions, clearing the territory map.

It's a pity that Yunmengland can only cover a distance of more than five kilometers at present. If it can achieve complete coverage, this work will be much easier.

But now the Yunmeng Realm is far from growing to cover the entire territory, and Chu Xin can only rely on manpower to clean it up one by one.

There are basically no large animals, mainly small things like snakes, rats, insects and scorpions. They are not strong, but they are very troublesome to find.

Therefore, the progress of this cleaning work was much slower than Chu Xin expected.

Taking advantage of this time, Chu Xin checked the function of the sound wave collection tower that had just mutated.

After the establishment of the territory, about three or four hundred watchtowers were built one after another. This is the second time that there have been mutated watchtowers.

Speaking of which, after the first reconnaissance tower was established, it has not been used much until today, and it has been eating ashes in the territory.

But this is not to say that the mutant watchtower is useless, it's just that the territory has not encountered any decent war, otherwise the role that the scout tower can play is quite huge.

As for today's sound wave collection tower, its function is very simple, that is, it can collect all the sounds within one kilometer around the tower, and then translate them.

It is a bit like a bug, and it is invisible on the map. It is an excellent reconnaissance defense tower, which can steal the enemy's intelligence silently.

The function is really powerful. If the sound wave collection tower is an ordinary watchtower that can be built at any time, then it goes without saying.

But as a mutated watchtower, there is a very small chance that one or two will mutate, so it seems a bit tasteless.

The characteristics of the sound wave collection tower determine that it must have a clear target, and it must be built near the target in order to show its effect.

But now that it has mutated, within an hour, Chu Xin must build it on the map, otherwise it will disappear directly. It is impossible for him to say that the sound wave collection tower should be left to wait for a large-scale war in the future before construction.

Without hesitating for too long, he directly placed the sound wave collection tower at the place where the final battle will take place three days later. At that time, he may be able to detect the order of Clayman's side in advance.

After Chu Xin completed the construction of the sound wave collection tower, messages began to pop up in the information storage column.

"What happened outside, there are so many terrible breaths, so dangerous!"

"Sister, brother, brother wants to mate with you."

"So hungry... so hungry..."

……

The sound wave collection tower directly translates the sounds of nearby small animals. It does not have any screening function. All sound waves that have the function of information transmission are collected and converted into text information and stored. …

The world of these small animals is really rich, Chu Xin said with emotion, and closed the sound wave collection tower.

The cleaning of the alien beasts in the territory is still going on, and the progress is not too fast. Even if Chu Xin guides them to the vicinity of the target area, it will take a while to find the target.

Only Cao Tuan made the fastest progress.

In the end, it took more than two hours to finally clean up all the alien beasts in the territory.

"Reminder, the alien beast group and other forces in the current territory have been eliminated, and the condition 4 for star promotion in the territory has been met!"

"Reminder, your territory has met all the star-up conditions. May I ask if you want to increase the star level?"

"Yes!"

What Chu Xin was waiting for was this moment. After such a long time of hard work, he was finally going to be successfully promoted to the four-star territory.

The conditions for three stars to be promoted to four stars are already so harsh and complicated. I don't know what the conditions will be for four stars to continue to be promoted in the future.

Following Chu Xin's confirmation, a series of reminders quickly appeared in the upper left corner.

"Reminder, your territory has been upgraded to four stars, unlock basic buildings: ranch, barracks, grocery store, high-end residential buildings, medical hall, carpenter's hut; unlock city defense weapons: wood, falling rocks, fire oil; unlock border defense buildings: boundary markers. "

"Reminder, due to the increase in the star level of the territory, you have a chance to use the territory editing function, which can adjust the current buildings in the territory, and the meditation will be done automatically. Expiry date: today."

"Hint, your black castle has been upgraded!"

“提示，晋升已达成，恭喜你的领地终于跨入中级领地的行列。你已获得晋升奖励，可从以下九项奖励中选择三项作为晋升奖励：1.指定三座领地建筑晋升到四星；2.获得随机四星精英兵种巢穴1个；3.获得高级技能人才10名；4.获得大型资源包*5；5.获得五星兵种100名；6.可任选领地一变异建筑，将其固化为常规建筑（仅限基础建筑变异）；7.解锁空间残余信息清除功能；8.可随机获得一项四星特殊建筑；9.可随机解锁一个四星战争副本。”

A series of system prompts popped up, and Chu Xin was a little dizzy. What surprised him was that there was a territory promotion reward this time.

This has never happened in the past, perhaps because this time it has broken through the hurdle of three to four stars.

Chu Xin was blindsided by the nine rewards. To be honest, he wanted them all.

Special buildings, high-level talents, elite units... most of the options are extremely attractive to him.

Chu Xin was not in a hurry to make a choice, but checked several options that she still had doubts about, the first, sixth, and seventh options.

These three items are quite special, so Chu Xin is special.

The first upgrade building includes special buildings, which means that the Bone Altar and Goblin Research Institute in Chu Xin's territory are all objects that can be upgraded.

The sixth item is optional mutated building solidification, that is, the buildings that can be mutated from basic buildings such as advanced animal pens, scout towers, and sound wave collection towers can be transformed into ordinary buildings that can be built at any time.

The seventh item is also Chu Xin's most important item. This function can clear the space coordinates that were once anchored near the territory at a certain cost, but it cannot completely clear the plane coordinates. …

In other words, after clearing, the next time the enemy comes, they need to re-anchor to new coordinates, and they will randomly appear in other places in the Darklands, instead of where they were last time.

This function is undoubtedly extremely important. It is self-evident for the security of the territory, and Chu Xin chose this function without hesitation.

There are too many enemies in the territory now, Zerg, Undead, and Arcane Continent. If the space coordinates anchored by the opponent can be completely cleared, it will be very difficult for the opponent to find themselves on the edge of the dark land. .

When it comes to development, Chu Xin still thinks that Gou's life is the most important thing.

There were still eight options left, and after struggling for a while, Chu Xin chose to use the method of elimination.

First of all, five-star arms and large resource packs can be ruled out. There are many channels to collect resources, and five-star arm territories also have an endless stream of army lairs.

The next thing to exclude is the lair of the four-star elite unit. Although Chu Xin was a little moved by the title of elite, he didn't know what unit would come out randomly.

And four stars, the level is indeed a little lower, Chu Xin doesn't like it now.

The fourth thing to exclude is the four-star war dungeon. The reason for excluding this item is also very simple. Chu Xin simply feels that he needs too many dungeons now, and he might not have the energy to brush another one.

The contents of several dungeons such as the Crystal Defense Battle, the Battle of Sishuiguan, and the Green Devil Tribe have not yet been released. It will take a lot of time, and Chu Xin doesn't want to add more burdens.

And the four-star dungeon, the upper limit of things produced is also there.

After eliminating four in one breath, there are still four options left, choose two out of four, which is much simpler.

But for these four items, Chu Xin is very excited. Designated building star upgrades, high-level skilled personnel, random four-star special buildings, and solidified mutant buildings are all needed by the territory.

After hesitating for a while, Chu Xin still excluded the item of high-level skilled personnel.

To be honest, this option is really exciting, and there is indeed a great shortage of such talents in the territory.

However, these high-level skilled talents cannot be specified in their category. It can only be determined that the acquired talents possess high-level skills.

If it is possible to specify the type, Chu Xin is very interested.

Choose two out of three, the fewer options you have, the more confusing it is.

After hesitating again and again, Chu Xin ruled out the sixth item, mainly for the current mutant buildings, which he felt were not worth it.

The only thing with a higher value is the sound wave collection tower and the high-level animal pen, but these two objects are easy to replace. He decided to put the rewards on special buildings.

There are currently several special buildings in the territory, such as the Bone Altar, Goblin Research Office, Purple Bamboo Forest, Rainbow Spring, Soul Awakening Hall...these are all buildings of great value, and Chu Xin feels that choosing these two rewards should not be too bad.

The three designated buildings were promoted, and Chu Xin chose two bone altars and the goblin research room. These are also the few low-star buildings with some value in the territory.

Of course, he also wanted to upgrade the Rainbow Spring, the Gene Replication Center, and the Hall of Awakening Souls. Unfortunately, these buildings have already reached four stars and above. If Chu Xin uses these buildings, he will be downgraded. …

It takes an hour to upgrade the three buildings, the Bone Altar, and two hours to the Goblin Research Office. If you want to see the results of the promotion, you have to wait.

As for the random four-star special building, it is called the Agricultural College.

Its function is also very simple. The efficiency of anyone in the territory to learn agricultural skills such as plowing, seedling raising, and harvesting is increased by five times. The efficiency of various agricultural technology research such as new variety cultivation, soil fertility research, and agricultural machinery manufacturing is increased by 100%, and the output of the territory's farmland is increased. 50%.

The function of the Agricultural College is quite powerful. It can not only help the territory quickly cultivate qualified farmers, but also speed up the efficiency of various agricultural research. The most important thing is that it also has the effect of increasing the overall production of the territory.

With the addition of the black land and various output bonuses from the territory, Chu Xin felt that the grain output per mu in the territory would reach a rather exaggerated level in the future.

Just the last production increase effect alone made him feel that this special building was right.

Chu Xin then looked at the function panel. He remembered unlocking the space residual information clearing function. He didn't know the specific cost of this function.

"Reminder, the residual information of the space can be cleared near the current territory: Wormhole (Zerg World, destroyed, chaotic); Bone Gate (Undead World, destroyed); Unknown Portal (Arcana Continent, hidden, closed); Terran Portal (Emerald Continent, closed), please select the object to be cleared."

With the selection of this function, Black Castle immediately searched for four targets, all of which were connected to Chu Xin's territory. He guessed that there should be a rough search standard.

For example, there is a certain grievance relationship with the territory or the condition that it is within a certain range.

Chu Xin immediately chose the unknown portal in the Arcane Continent to check the erasure cost, and the results showed that [-] tons of magic crystals were needed.

So expensive!
Although Chu Xin had expected the high cost of erasing spatial information, he did not expect it to be so expensive.

Three hundred tons, converted into the measurement unit of Black Castle, is about [-] units. Chu Xin estimated that the dwarves turned upside down the mine veins in the abandoned mine to get almost this much.

Chu Xin took the second best option and chose the second target, which was the more threatening Zerg.

Although the sand of chaos collapsed the wormhole, Chu Xin was not sure whether the Zerg still had the space coordinates here.

Because compared to the weaker undead world, the Zerg is much more advanced in the research of space transmission.

The cost of erasing this wormhole of the Zerg is much cheaper, only one ton of magic spar is needed.

As for the Gate of Bones, it is even less, [-] kilograms can be done, and the portal of the Emerald Continent requires an astonishing [-] tons.

Chu Xin reckoned that the higher the integrity of the portal, the more expensive it would be to erase it, while the ones that were destroyed, the distance was close, and the level of the plane space was low, the price would be cheaper.

All that is needed to erase the space information is the magic spar, and it happens that Chu Xin has about [-] units of magic spar on hand, and he can directly erase all the residual space information of the wormhole and the gate of bones.

The Emerald Continent cannot be cleared in such a short period of time, and Chu Xin is also somewhat reluctant to clear it. He still hopes to have the opportunity to establish a portal with the Emerald Empire in the future, just like the world of the undead.

If the space information of the Emerald Continent is erased, even if there is a time-space gate in the territory in the future, it will definitely not be possible to go to the Emerald Continent.

However, there must be a way to erase the space information on the Alpha Continent. Although facing Clayman this time, it can be delayed for a while, but there is no guarantee that someone stronger will not appear next time.

To be on the safe side, it is better to cut off all connections with the world that have enmity with the territory, and it is best to develop steadily.
