More than 40,000 stones were smashed down, and the scope of the territory was finally expanded to the limit. Next, the territory was promoted to four stars, and only the last promotion condition was left. The alien beasts in the territory were cleared.
With a territory of ten kilometers, this is a quite vast area.
Thanks to Chu Xin's extensive preparation work, the hunting team in the territory cleaned up day and night and removed the more troublesome black finches and fire ants, so the remaining ones were not a problem.
After the territory is expanded, all targets that do not belong to the territory will be clearly displayed on the territory map.
Chu Xin commanded the grass regiment and all the troops in the territory, and began to gradually clear up the territory map in four directions.
Unfortunately, Yunmengjing can currently only cover a distance of a little more than five kilometers. If full coverage can be achieved, this task will be much easier.
Unfortunately, Yunmeng Realm is far from growing to cover the entire territory, so Chu Xin can only rely on manpower to clean it up one by one.
Large exotic beasts basically no longer exist, mainly small things like snakes, rats, insects, and scorpions. They are not very strong, but they are very troublesome to find.
Therefore, the progress of this cleanup 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 territory was established, about three to four hundred watchtowers were built. This was the second time a mutated watchtower appeared.
Speaking of which, after the first reconnaissance tower was built, it has not been used much to this day and has been gathering dust in the territory.
But this does not mean that the mutant watchtower has no role, it is just that the territory has not encountered any decent wars, otherwise the role that the reconnaissance tower can play is still 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 somewhat similar to a bug, and it is invisible on the map. It is an excellent reconnaissance defense tower that can steal enemy intelligence silently.
The function is indeed powerful. If the sound wave collection tower is an ordinary watchtower that can be built at any time, its function goes without saying.
But as a mutant watchtower, there is a very small chance that one or two of them can be mutated, which makes it seem a bit useless.
The characteristics of the sound wave collection tower determine that it must have a clear target and be built near the target in order to be effective.
But now that it has mutated, Chu Xin must build it on the map within an hour, otherwise it will disappear directly. It is impossible for him to say that he will put this sound wave collection tower aside and wait for a large-scale war in the future to build it.
Without hesitating for too long, he directly placed the sound wave collection tower at the place where the decisive battle would take place three days later. At that time, he might be able to detect the order of Kleiman's side in advance.
As Chu Xin completed the construction of the sound wave collection tower, messages began to appear in the information storage column.
"What's happening outside? There's so much scary smell, so dangerous feeling!"
"Sister, brother, I want 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 with the function of transmitting information are collected and converted into text information and stored.
The world of these little animals is really rich. Chu Xin sighed and closed the sound wave collection tower.
The cleanup of alien beasts in the territory is still going on, and the progress is not too fast. Even if Chu Xin guides them to the target area, it will take some time to find the target.
Only the grass group made the fastest progress.
In the end, it took more than two hours to finally clear away all the strange beasts in the territory.
"Reminder, the alien beast group and other forces in the current territory have been eliminated, and condition 4 for star promotion in the territory has been met!"
"Reminder, your territory has met all the conditions for star promotion. Please ask if you want to increase the star rating."
"yes!"
This is the moment that Chu Xin has been waiting for. After such a long period of hard work, he will finally be successfully promoted to the four-star territory.
The conditions for promotion from three stars to four stars are already so demanding and complicated. I wonder what the conditions will be for those who continue to be promoted to four stars in the future.
As Chu Xin confirmed, a series of prompts quickly appeared in the upper left corner.
"Tip, your territory has been upgraded to four stars. Unlock basic buildings: pastures, military camps, grocery stores, high-end residences, medical centers, and carpenter's cabins; unlock city defense weapons: wood, falling rocks, and kerosene; unlock border defense buildings: boundary monuments. "
"Tip, due to the improvement of the territory's star level, you will get an opportunity to use the territory editing function. You can adjust the current buildings in the territory, and the silent recitation will be carried out automatically. The period of use is today."
"Tip, your black castle has been upgraded!"
"Reminder, promotion has been achieved. Congratulations, your territory has finally entered the ranks of intermediate territories. You have received promotion rewards, and you can choose three from the following nine rewards as promotion rewards: 1. Designate three territory buildings to be promoted to four stars; 2 Obtain 1 random four-star elite unit lair; 3 Obtain 10 high-level skilled personnel; 4 Obtain 5 large resource packs; 5 Obtain 100 five-star units; 6 You can choose a mutated building in the territory and solidify it into a regular building (only (limited to basic building mutation); 7 unlocks the space residual information clearing function; 8 can randomly obtain a four-star special building; 9 can randomly unlock a four-star war copy."
A series of system prompts appeared, and Chu Xin was a little dizzy. What surprised him was that there was a territory promotion reward this time.
This has not happened before, perhaps because this time it has broken through the big barrier of three to four stars.
Chu Xin was dazzled by the nine rewards. To be honest, he wanted them all.
Special buildings, high-level talents, elite units... most of the options are extremely tempting to him.
Chu Xin did not rush to make a choice, but looked at several options that she still had doubts about, including the first, sixth and seventh items.
These three items are quite special, so Chu Xinghe pays more attention to them.
The first upgrade building includes special buildings, which means that the Bone Altar and Goblin Research Institute in Chu Xin's territory are all upgradeable objects.
The sixth item, the solidification of optional mutated buildings, means that buildings that have been mutated from basic buildings such as advanced animal pens, reconnaissance towers, and sound wave collection towers can be transformed into ordinary buildings that can be built at any time.
The seventh item is also the one that Chu Xin is most concerned about. 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 enemies come over, they need to re-anchor new coordinates. They will randomly appear in other places in the dark land, instead of appearing where they were last time.
This function is undoubtedly extremely important. It is self-evident for the security of the territory. Chu Xin chose this function without hesitation.
There are too many enemies in the territory now, including Zerg, Undead, and Arcane Continent. If the opponent's anchored space coordinates can be completely cleared, it will be very difficult for the opponent to find you on the edge of the Dark Land. .
When it comes to development, Chu Xin still believes that life is the most important thing.
There were eight options left. After struggling for a while, Chu Xin chose to use the elimination method.
First of all, five-star troops and large resource packs can be excluded and are dispensable. Resources can be collected through many channels, and five-star troop territories also have troop lairs that continuously produce them.
The next thing to exclude was the four-star elite troop nest. Although the name of elite made Chu Xin a little excited, he didn't know what troop types would randomly appear.
Moreover, the level of four stars is indeed a bit low, and Chu Xin is not too fond of it now.
The fourth item to exclude is the four-star war dungeon. The reason for excluding this item is also very simple. Chu Xin simply feels that there are too many dungeons that he wants to play now, and he may not have the energy to add another one.
Things in several dungeons such as the Crystal Defense War, the Battle of Bishui Pass, and the Green Goblin Tribe have not been released yet. This requires a lot of time, and Chu Xin does not want to add to the burden.
Moreover, the upper limit of what can be produced in a four-star dungeon is also there.
After eliminating four in one go, there are still four options left. Choose two of the four, which is much simpler.
But Chu Xin was very excited about these four items. Designated buildings with star upgrades, high-level skilled talents, random four-star special buildings, and solidified mutation buildings were all needed by the territory.
After hesitating for a while, Chu Xin still excluded high-level skilled talents.
To be honest, this option is really exciting, and the territory is indeed extremely lacking in such talents.
But the type of these high-level skilled talents cannot be specified. It can only be determined that the talents obtained have high-level skills. This range is very large. Advanced gambling skills... advanced begging skills... anything is possible.
Chu Xin would be very interested if the type could be specified.
Choose two out of three. The fewer the options, the more confusing it is.
After much hesitation, Chu Xin eliminated the sixth item, mainly because he felt that it was not worth it due to the several mutated buildings.
The only ones with greater value were the sonic collection tower and the advanced animal pen, but these two items could easily have substitute functions, so he decided to invest the rewards in special buildings.
There are currently several special buildings in the territory, such as the Bone Altar, Goblin Research Laboratory, Purple Bamboo Forest, Rainbow Spring, Soul Awakening Hall... These are all buildings of great value. Chu Xin feels that choosing these two rewards should not be a big loss.
Among the three designated buildings for promotion, Chu Xin chose two bone altars and the Goblin Research Laboratory, which are also one of the few low-star buildings of some value in the territory.
Of course, he also wanted to upgrade the Rainbow Spring, Gene Replication Center, and Soul Awakening Palace. Unfortunately, these buildings had already reached four stars and above. If Chu Xin used these buildings, they would be downgraded.
It takes one hour to upgrade the three buildings, the Bone Altar, and two hours to the Goblin Research Laboratory. If you want to see the results of the promotion, you have to wait.
As for the random four-star special building, it's called the Agricultural College.
Its function is also very simple. The efficiency of anyone in the territory in learning agricultural skills such as farming, 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. The output of farmland in the territory is increased by 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 can also increase the production of the entire territory.
With the addition of black soil and various output bonuses in the territory, Chu Xin feels that the territory's grain output per mu will reach a quite exaggerated level in the future.
Just the last production-increasing effect alone made him feel that this special building was the right choice.
Chu Xin then looked at the function panel. He remembered that he had unlocked the space residual information clearing function, but he didn't know the specific cost of this function.
"Tip, the residual information in the space near the current territory can be cleared: Wormhole (Zerg World, destroyed, chaotic); Bone Gate (World of the Undead, destroyed); Unknown Portal (Arcane Continent, hidden, closed); Human Portal (Emerald Continent, closed), please select the object to clear."
With this function selected, Black Castle immediately retrieved four targets, all of which were related to Chu Xin's territory. He guessed that there should be a rough search standard.
For example, there is a certain grudge relationship with the territory or a condition within a certain range.
Chu Xin immediately chose the unknown portal in the Arcane Continent and checked the erasure cost. The results showed that three hundred tons of magic crystal 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 Black Castle's measurement unit, is about 30,000 units. Chu Xin estimated that the dwarves turned over the veins in the abandoned mines to get almost this much.
Chu Xin retreated to the next best thing and chose the second target, the Zerg, which was a greater threat.
Although the sand of chaos caused the wormhole to collapse, Chu Xin was not sure whether the Zerg still had the spatial coordinates here.
Because compared to the relatively weak world of the undead, the Zerg are much more advanced in the research on space teleportation.
The cost of erasing the Zerg wormhole is much cheaper, only requiring one ton of magic crystal.
As for the Bone Gate, it's even less. Four hundred kilograms can be done, while the Emerald Continent's portal requires an astonishing five hundred tons.
Chu Xin estimated that the higher the completeness of the portal, the higher the price of erasure, while the destroyed, close, and low-dimensional space would be cheaper.
All that is needed to erase space information is magic crystal. It just so happens that Chu Xin has about 5,000 units of magic crystal on hand, which can directly erase all the remaining space information in the wormhole and the Bone Gate.
The Emerald Continent will definitely not be cleared in this short time, and Chu Xin is somewhat reluctant to clear it in his heart. 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 the time and space gate appears again in the territory in the future, it will definitely not be possible to go to the Emerald Continent.
However, the space information on the Offa Continent must still be erased. Although it can take a while to face Kleiman this time, there is no guarantee that someone stronger will not appear next time.
To be on the safe side, it is best to cut off all connections with the world that has enmity with the territory so that it can develop stably.
