After processing the materials dropped by the black wolf, Lin Xu took another look at the items dropped by the two-headed bird.

The bird's droppings were quite ordinary; it was just a single feather from its head.

Because it has two heads, this bird lost two feathers.

Lin Xu had seen the uses of these feathers in the basics of mechanics; they weren't used to make feathered arrows, but rather to make levitation equipment.

For example, levitation boots, levitation capes, and even flying carpets from magical stories can all be made from these bird feathers.

However, to weave something like this, you need more than just two bird feathers; you also need other auxiliary materials.

Therefore, these two-headed bird feathers are only suitable for collection for now, and there is no condition to use them yet.

After eliminating so many dark creatures, Lin Xu naturally collected quite a bit of loose soil along the way.

The island's ocean blocks have now been stacked up to thirty layers.

The forest blocks were also stacked more than twenty times.

In addition, Lin Xu also obtained some new mountain stone blocks.

These rock blocks can be used to further enhance the Fountain of Life, or they can be accumulated.

If this type of block is large enough and is combined with resource seeds, it can generate mountains.

These mountains can be used to produce stone or mineral veins.

If combined with stacking abilities, this block-based resource would be even better, and creating an infinite number of mineral veins wouldn't be difficult.

Therefore, Lin Xu deliberately kept the mountain stone blocks away and did not integrate them all into the Fountain of Life.

What surprised Lin Xu the most during this accumulation was that when the ocean blocks were stacked to the thirtieth layer, a hidden feature suddenly appeared.

[Foundation Seed: This block is magical enough to generate foundation pillars, preventing itself from becoming mere dust again (currently, the maximum number of foundation pillars generated can reach 30)]

This new feature shocked Lin Xu.

Because foundation pillars are not something that are easy to obtain.

According to publicly available information, if an island lord wants to obtain a foundation pillar, he either needs to purchase or plunder the original territory of other island lords, or find some very precious relics and obtain this resource from them.

Rumor has it that some top old nobles have mastered the method of casting foundation pillars, but the cost is extremely high, and nobles with their wealth would not easily cast foundation pillars.

However, the island lord's territorial expansion is inseparable from the foundation pillars. After all, few people can infinitely upgrade the foundation pillars like Lin Xu, which can support an extremely exaggerated size of territory.

Most lords have relatively basic foundation pillars, and to prevent unforeseen circumstances, they rarely allow the foundation pillars to support the maximum number of territories.

Therefore, most lords' territories are as large as the number of their pillars, and at most they only expand outwards by a small circle, never expanding too much.

Every island owner is extremely eager for foundation pillars, and no one would complain about having too many foundation pillars.

However, Lin Xu has now actually mastered the method of creating the foundation pillar, which is even more advanced and exaggerated than the creation of any energy block.

If others find out, they will never let go of Lin Xu's secret and will use every means to find out about his abilities.

Lin Xu realized this, but he didn't feel any danger or tension. Instead, a glint flashed in his eyes.

He now has another trump card up his sleeve.

This ability to regenerate the base is clearly not unique to ocean blocks, but rather a natural ability that arises when blocks are stacked to thirty layers.

The reason why the previous blocks did not exhibit this characteristic is because Lin Xu stacked the base pillars and blocks together, and the number of base pillar layers generated by the blocks could not exceed the limit of the blocks.

Therefore, Lin Xu had not been able to detect this hidden characteristic all along.

But now, he is certain that he possesses this ability.

In the future, when he expands his territory, he may not need to consider the limitations of the pillars, or even upgrade them.

Because once land blocks are stacked to thirty layers or more, foundation pillars will be generated naturally, and these foundation pillars will continue to upgrade until they reach the number of stacked layers of the land itself.

Furthermore, he can now infinitely increase the land area simply by acquiring unlimited amounts of floating soil and stacking similar blocks, without having to worry about the island being unable to support it.

Even his base level and island lord level will continuously increase as the number of land layers increases.

This is a huge advantage.

Lin Xu originally planned to hunt down those noble lackeys, which would surely bring him a large amount of territory.

If he doesn't find a way to regenerate his foundation pillars, even if his foundation pillars are of extremely high level and can support a large amount of land, he might still not be able to swallow up so much territory, and might even be forced to give up a large amount of spoils and territory.

But now, he has no such worries at all.

Lin Xu was overjoyed. He used his island master perception to sense that a base was beginning to emerge under the ocean block, and that base was constantly upgrading at a not-too-slow speed.

Around midnight tonight, this base will be able to be upgraded to thirty layers, which is already considered a fairly strong base.

His only regret was that he could only stack blocks, but he had not yet mastered the method of separating a part of the stacked blocks.

Otherwise, he could infinitely strip away newly created land and pillars, and infinitely create land and blocks.

Even if he is perfect in every way, as long as he quietly peels away and stacks the foundation pillars for a few years, making the foundation pillars reach millions of layers, then he will be invincible.

It's getting late, and the day is coming to an end. The island world is entering night.

Lin Xu then gathered many elves and brought them to the front of Xiao Yu's newly built house.

Xiaoyu's skills are indeed quite good.

The house is now much larger, at least 400 square meters, and its exterior has been greatly improved, transforming from a rough brown wooden house into a beautiful house with a red roof and brown walls.

Upon entering the house, the previously somewhat separate bathroom, kitchen, and bedroom rooms have now been merged into one building.

Xiaoyu also left extra space for a living room, an entertainment room, and a workout room, and even added two extra bedrooms, which also contain some exquisite furniture.

Lin Xu led Tao Yao and the other girls into the house. Tao Yao clapped her hands happily and rushed over to hug Xiao Yu.

The other peach fairies didn't stand on ceremony either, grabbing Xiaoyu and rubbing their faces against hers.

"Xiaoyu, you did a fantastic job!"

"Lady Xiaoyu, you are amazing!"

"Lady Xiaoyu, you are my idol!"

The numerous peach fairies chattered incessantly, completely burying Xiaoyu in a sea of ​​white flesh:

"Uh, uh, everyone..."

Xiaoyu then looked at Lin Xu.

Lin Xu smiled and nodded:

"Well done, Xiaoyu!"

Xiaoyu was completely overwhelmed, utterly immersed in happiness and a sense of accomplishment.
