Chapter 306: Lord's Mansion Finally Promoted to Level Six

For Shen Fei, the biggest threat that other kingdoms can bring is obviously not a threat of force.

Rather, it is a threat of building cities and snatching treasure chest rewards from the Great Wilderness World.

After all, after limiting the distance between each altar to be greater than one thousand kilometers, the number of altars built in the entire world is limited. In this case, every time other kingdoms build an altar, the Dark Night Kingdom will have one less altar to build, and the treasure chests that Shen Fei can obtain by conquering the entire world will also be reduced.

Therefore, it is necessary to suppress other kingdoms.

Not to mention, this is obviously the main competition between the kingdoms conquered by the heavens.

This is also the main purpose of Shen Fei's attention to this Rui Kingdom, and even to other kingdoms.

However, the specific approach is not easy to decide at present.

Because Shen Fei and the heroes speculated that when other kingdoms also entered the Great Wilderness World, the lord system may undergo certain changes.

But at present, everything is unknown.

Just wait.

While keeping a close eye on it, two days later, the lord's mansion finally reached the time for another promotion.

"It's not easy to upgrade the Lord's Mansion to Level 6 in more than four months." Shen Fei sighed, "This will get slower and slower in the future."

"But the sense of time passing will get faster and faster." Li Tingyu stood beside Shen Fei.

She has been busy upgrading the buildings in the territory during this period.

It's rare to take a break at this moment.

In fact, with the increase of domestic heroes in the kingdom and the improvement of various departments and orders, Li Tingyu should have been more and more relaxed, but the development of the kingdom and the territory is getting faster and faster. Just controlling some important matters requires a lot of time.

Fortunately, Li Tingyu herself is also enjoying it.

"It's time." Shen Fei looked at the last building upgraded to Level 5, and he couldn't help but cheer up and directly upgraded the Lord's Mansion.

Although the upgrade of the Lord's Mansion itself will not change anything, it will take a short time.

In just a moment, the area of ​​the territory has expanded again.

The diameter directly became 36 kilometers.

You know, the diameter of the small world is only 132 kilometers now.

Even a level 5 alliance city can no longer accommodate Shen Fei's territory.

"It's doubled." Shen Fei was a little surprised at this moment, "If every upgrade is doubled, this exponential growth is indeed a bit scary."

"But the further you go, the more difficult it will be to upgrade." Li Tingyu immediately checked the time and source crystals required for the upgrade of the legendary buildings, and couldn't help but sank her tone, "It takes 18 days to upgrade the legendary building to level 6, and this is the result after the total reduction exceeds 70%."

Calculated in this way, the upgrade time of many buildings in the territory is definitely more than five years.

The number of buildings in the territory has already accumulated to a terrifying level.

Of course, this is without using any acceleration props.

The time acceleration props in a gold treasure chest are 20 days.

The time acceleration props in thirty-six gold treasure chests are more than two years.

From this point of view, the total upgrade time of five years does not seem to be exaggerated.

However, as the gold treasure chests are constantly opened, there will be more and more buildings.

In general, building upgrades are still a huge pressure for high-level lords.

"Let's do it step by step." Shen Fei seemed very calm, "As you said, as the development progresses, the perception of the flow of time will become slower and slower. Apart from anything else, the two months after coming to the Great Wilderness World feel much faster than the two months in the initial world."

When he first got to know the world, especially when he just crossed over, Shen Fei hardly dared to breathe. Every hour of time had to be used efficiently, and even rest was timed.

It's nothing like now.

Every day, you only need to train and study, and time will pass quickly.

Li Tingyu heard this and nodded gently, and said nothing more.

She was just a little worried that with this trend, it would be more and more difficult to upgrade her master's territory, and even become a burden.

However, there is really no need to think too much at the moment. After all, the advantages of her master are not ordinary, and they are gradually expanding.

The growth of a time acceleration area alone is enough to offset the upgrade disadvantage brought by the number of buildings.

"Let's start, upgrade the Kingdom Center and the Alliance Center first." Shen Fei said.

The reason why he was waiting for the Lord's Mansion to be upgraded here was not for the increase in territory, but mainly for the changes that might occur in some important buildings.

Especially the malls of the Kingdom Center and the Alliance Center.

At this moment, Li Tingyu nodded and directly used her subordinate secondary system to operate the upgrade.

As the time props were consumed, the upgrade time of the Kingdom Center was only the last five hours.

Shen Fei then put the fourth large time acceleration area originally used for the time house on the Kingdom Center.

Directly reduced to a little over an hour.

It was gone in a flash.

At the moment when the sixth-level Kingdom Center was upgraded, Shen Fei couldn't wait to open the Kingdom Mall.

"Sure enough, the number of goods has increased again. The number of goods in the epic mall has increased to fifteen. There are three more epic building upgrade coupons." Shen Fei took a rough look and found that this time the number of goods increased, and the legendary mall still had no changes. He couldn't help but sighed.

It can't be said to be useless.

More goods means a greater probability of useful goods.

For example, epic building upgrade coupons, which are more important for the growth of kingdom lords, now basically appear in two sets every week, that is, more than six.

And rare building upgrade coupons, even three sets, even four sets, and even refreshed five sets again, directly get 25 upgrade coupons.

These upgrade coupons are gradually strengthening the strength of the lords in the kingdom, and have greatly increased the motivation of the lords to fight.

Therefore, the growth advantage brought by building upgrades is still very strong.

Shen Fei waited for a while again, and the Alliance Center also completed the rapid upgrade.

This time, the Alliance Mall did not change as expected.

The last basic building "Versatile Building" did not appear in the Alliance Mall.

However, this upgrade is not without any changes, because there is a new thing in the Alliance Building.

——Alliance Crossbow Tower.

"It is the same as the crossbow tower that comes with the Alliance City, but it cannot be built on the Alliance City Wall, but can only be built in the Alliance Territory. So that's it, this is to ensure the safety of the Alliance territory." Shen Fei saw the role of such a new Alliance building at a glance.

"It has a significant effect." Li Tingyu also checked the information and gave a direct evaluation, "Especially for use near resource points, my lord, it seems that it is necessary to build a few alliance flags, at least to spread to the location of resource collection points."

During the two months in the Great Wilderness World, the Dark Night Kingdom did not even build a single alliance flag.

The reason is very simple, there is no need.

Other kingdoms have not arrived yet, and there is no need to attack cities around the alliance territory. Moreover, there is no gray fog to be dispelled in this world. In addition, resource collection is still in the stage of surrounding the territory, and there is no need to increase the construction of trade centers.

But now, with this kind of defensive building that can be built directly on the alliance territory, the value of the alliance flag, or the alliance territory, has been greatly improved.

Not only can it reduce a large number of defensive force deployments, but it can also increase the scope of resource collection.

"This kind of building level can also be upgraded. In this way, test the power first, and then prioritize the deployment according to the degree of danger. The idle force deployment will be invested in the troops for monster extraction." Shen Fei simply gave a few instructions.

Then, Shen Fei looked at the Wanyao Spiritual Pond again.

The upgrade of this building is a little troublesome, but with the spiritual fruit and spiritual medicine resources in the territory now, there is no problem.

There was no ambiguity at the moment. After all, a lot of level 5 Wanyao Spiritual Water had already been stored, and it was upgraded directly at this moment.

After waiting for a while, as the blue light faded, the pond in front of him did not change much except for a slight increase in area.

Shen Fei waved his hand and took some directly.

He took it on the spot.

Then he raised his eyebrows.

"The medicinal properties have increased by about two times, which can only be regarded as a normal upgrade change for this spiritual water."

A mere two times is nothing at all. The last time the level 4 was upgraded to level 5, the medicinal properties were directly increased by nearly ten times.

In fact, this two-fold increase can make Shen Fei more certain that there must be other changes in this upgrade.

Shen Fei looked at it for a long time, but couldn't see the reason.

Simply, send the message directly to the research center of the territory.

Just a moment later, an old man with white hair, a youthful look, and a celestial spirit came hurriedly.

"Gong Dan greets the Lord." This old man was the first hero of the master of medicine recruited by Shen Fei.

The reason why it is said to be the first is that in the hero recruitment that received thirty-six gold treasure chests in one go not long ago, another master of medicine was recruited.

However, the master of alchemy from the fantasy world is still improving his strength in the training building.

So Gong Dan had to come.

"No need to be polite, take a look at the changes in the upgraded Wanyao Lingshui?" Shen Fei asked directly.

"Yes!" Gong Dan heard that the Wanyao Lingtan in front of him had been upgraded, and his eyes seemed to burst with light.

It has been more than a month since he was recruited and came to this magical little world. During this period of time, what has amazed him the most and made him happiest is the extremely magical Wanyao Lingtan before him.
