Chapter 445

Energy Cores,

are necessary resources for the development of Level 4-6 territories.

They can fully replace territory energy for use,

yet possess functions that territory energy lacks,

and because of their non-tradable nature,

they can be said to be absolutely precious items.

To give a simple example,

Energy Cores can replace the material requirements

needed when upgrading buildings.

Rare Grade and below building materials only require one Energy Core to replace.

Legendary requires 10, Shi Shi requires 100, and Mythical requires 10,000.

With them, the defensive buildings of Su Yu's territory

can be upgraded to higher levels.

The original materials can be used to construct new buildings,

while upgrades use Energy Cores as replacements.

After all, Energy Cores only provide what is needed for upgrades, not for construction.

Five days later, Su Yu had occupied his territory up to the limit.

The territory held by the Lord Crystal reached 10,000 grids.

Under the Shi Shi buff that doubles territory income,

every day, 20,000 Energy Cores can be obtained.

And to upgrade a Level 10 Rare Grade building

from Level 10 to Level 20,

55 core materials are required,

and these 55 core materials can be replaced by Energy Cores,

while other materials, being easier to obtain, can be used directly for upgrades.

Simply put, 55 Energy Cores can upgrade a Rare Grade defensive tower from Level 10 to Level 20.

A Legendary defensive tower requires 550.

Su Yu immediately used the more than 60,000 Energy Cores he had saved over these days,

upgrading 110 Legendary Grade laser towers to Level 20.

Since building modifications reset the level to 1,

he did not upgrade those Rare Grade laser towers.

And the combined trait of laser towers dictates that if upgrading, a batch must be upgraded first.

After all 5,000 laser towers are converted to Legendary Grade and all raised to Level 20,

his next target will be to upgrade the Flare Towers.

As for the other defensive towers,

their levels need not be rushed, serving as specialization against specific types.

Ultimate offensive power can be left to the Flare Towers and laser towers.

As for the upgrade of the walls...

the cost is too great; to be honest, Su Yu cannot quite afford to upgrade the Obsidian Walls.

Let alone, the current Obsidian Walls are in the process of expansion.

Wall-type buildings are constructed at a rate of one hundred meters per grid,

but upgrades must be done for the entire structure at once.

This also causes wall buildings to become one of the most difficult buildings to upgrade in the Battlefields of the Myriad Worlds.

Simply put,

upgrading walls within a thousand li radius,

from Level 10 to Level 11 requires 31,400 Energy Cores,

and from Level 10 to Level 20 requires 1,727,000 Energy Cores...

If one focuses solely on upgrading walls, that would undoubtedly delay the development of the territory.

After all, walls only serve to let you take hits and defend.

Listing walls as the first priority is unnecessary.

For most territories, troops are the first priority.

Crafting equipment for troops is the second priority.

Those like Su Yu, who prioritize defensive buildings first,

are usually cowardly turtle-fortress style lords.

Once productivity is raised, everyone starts building up territory combat power.

When summer passes, the territory power of the new generation of lords will all see an explosion.

"The reserved Obsidian mines should be enough to expand the Obsidian Walls to a thousand li radius..."

Su Yu sat cross-legged on the grass, pondering.

These past few days,

he had constantly traveled back and forth between his two territories,

The place he once stayed in increasingly resembled a territory of considerable scale.

Su Yu was very satisfied with the disguised territory.

After all, they had lived there for so long; Yiluo Di was reluctant to leave.

They often still stayed in the Lord's Mansion built atop Shanfeng.

The Lord's Mansion was a building unlocked after upgrading to a Level 4 Lord Crystal,

for the Lord to live in.

Purple teleportation light flared,

after glancing at the development of his true territory,

Su Yu returned to the disguised territory.

He had not moved the dragon bone specimens at the foot of the mountain and on the peak.

He continued to live there leisurely.

Until summer was about to end,

until the final seven days of summer were about to arrive,

Su Yu's inner doubts grew ever stronger.

Why, after dispatching a Butterfly Ninja,

did the cultivation civilization fall silent?

"Have you found the Butterfly Ninja?"

"No!"

"Have the two forces there been investigated clearly?"

"Roughly understood; they are very strong territory forces."

"Yaoxue Alliance and Tian Gu Mu, judging by their scale, their highest combat power level should exceed Level 60..."

Yan Fu frowned, listening to the report from the guard.

Level 60?

That area of Su Yu's territory,

why did it happen to have such two powerful forces blocking the way?

The Butterfly Ninja's betrayal and disappearance must surely be connected to them.

"Tian Gu Mu... the Undead race; their suspicion is the greatest."

Yan Fu murmured, feeling a severe headache.

Asking his territory to confront such a massive force,
