At this moment, Han Xing was also wearing a look of delight as he gazed at his warehouse.

This round of trade had earned him another 1.6 billion in material resources.

This speed of resource acquisition was truly unbelievable if spoken of.

With resources in hand, Han Xing began to extensively build various defense towers to enhance his combat strength.

The first batch prioritized the ones with the highest damage and power — the Thunderbolt Towers.

Now, the area surrounding Xingyu City was almost entirely encircled.

At this time, Han Xing pondered in a low voice: "The firepower intensity around Xingyu City is already saturated; perhaps it's time to choose other locations to build defense towers."

Then, he scanned across the territory.

Finally deciding.

To build the new batch of defense towers on the hillside.

After selecting the location, Han Xing began construction directly.

"Would you like to consume materials... to build Thunderbolt Tower*1?"

"Would you like to consume materials... to build Corrosion Tower*1?"

"Would you like to..."

Han Xing clicked continuously.

"Under construction..."

System prompts continuously appeared.

Bang! Bang bang!

Han Xing successively constructed over 30 Thunderbolt Towers, consuming a large amount of resources.

Then, next to the Thunderbolt Towers, he built hundreds of Ice Arrow Towers, Corrosion Towers, and Poison Arrow Towers.

Looking at the materials in the warehouse approaching depletion once again.

Han Xing smiled wryly.

"Damn it, I'm really being wasteful here."

"Earning billions in a day, spending billions, completely lacking the mindset of a hoarder."

Han Xing couldn't help but sigh about his money slipping away like water.

However, the consumption of these resources was entirely worthwhile.

In the words of a certain Master Ma.

Your money hasn't disappeared; it merely changed states to accompany you.

And his resources were transformed into more defense towers to protect the territory.

Just at this time, a system prompt appeared.

"The building in your territory, Big-beaked Bird's Nest, has been successfully constructed."

Hearing this prompt, joy sparkled in Han Xing's eyes.

"The nest is set up!"

He immediately made his way into the Dark Fire Stone Mine.

Finding that the scene inside had entirely transformed.

Where once an empty mine stood, there was now a huge bird's nest framework made of refined iron and wood.

Atop the framework lay a thick layer of dry grass.

The Dark Fire Stone emanated a scalding aura nearby, enveloping the entire mine in warmth.

At this moment, Han Xing stepped lightly on the soft dry grass, thinking.

"Wow, it's quite cozy here; it's making me want to lie down and nap."

It's undeniably said that the environment of this bird's nest was excellent.

Like a natural incubation chamber.

Perfect for nurturing life.

In front of Han Xing, the relevant information about the bird's nest appeared.

[Big-beaked Bird's Nest]: By consuming Spirit Cores, you can exchange for Big-beaked Bird Eggs for incubation.

By enhancing the technology level, you can increase the simultaneous incubation number of Big-beaked Bird Eggs and accelerate the incubation and growth speed of Big-beaked Birds.

[Technology 1]: Basic Bird's Nest Level 1 (Currently can simultaneously incubate 1000 Big-beaked Bird Eggs, requiring 36 hours for incubation.)

[Technology 2]: Accelerated Growth Level 1 (By feeding Spirit Cores, enhance the Big-beaked Bird Level; each level increase adds +1 to the Big-beaked Bird Level Limit.)

"Hmm? This thing is a bit different from the Wolf Cavalry and Minotaurs."

"It's incubated in batches!"

Han Xing was somewhat surprised.

He tried clicking the + sign behind the Basic Bird's Nest Technology, and a system prompt appeared.

"Would you like to consume materials: Refined Iron*10000, Wood*50000, Dark Fire Stone*5000, Mithril*250 to upgrade 'Basic Bird's Nest Level 1'?"

"Yes."

"Upgrade successful; the nest can now simultaneously incubate 1100 Big-beaked Bird Eggs, reducing incubation time to 35 hours and 50 minutes..."

Joy lit Han Xing's eyes, "Interesting. Upgrading 1 level increases the capacity by 100 eggs and shortens the incubation time by 10 minutes, right?"

Then, Han Xing continued to click to upgrade.

He clicked 48 times in succession, maxing it out.

Now, this technology had become.

[Giant Bird's Nest Level: max]: Currently can simultaneously incubate 6000 Big-beaked Bird Eggs, requiring 27 hours and 40 minutes for incubation...

"6000 eggs! That means by tomorrow, my territory can have the first squadron of Big-beaked Birds!"

Excitement welled in Han Xing's heart, and with a flourish, he directly spent 3 million Spirit Cores to exchange for 6000 Big-beaked Bird Eggs.

The next moment, numerous huge white eggs appeared within the Giant Bird's Nest.

6000 giant eggs scattered throughout the various corners of the nest.

In the warm environment, these eggs will soon hatch.

Han Xing nodded in satisfaction.

Very soon, he will have his first aerial units!

Then, he glanced at the Minotaur Camp and Wolf Cavalry Camp below.

Through uninterrupted summoning over the past two days.

Every single day, Han Xing had to expend almost a massive amount of Spirit Cores to summon Minotaurs and Wolf Cavalry.

But correspondingly, the results were very evident.

The Wolf Cavalry could appear every 5 seconds, while a Minotaur needed 10 seconds per summon.

Now, the number of Wolf Cavalry had surpassed 30,000, and Minotaurs had exceeded over 10,000.

Among them were many Leaders and Elite-level Minotaurs.

Currently, the entire territory was thriving with development.

Every day, new defense towers were completed.

Every day, more Minotaurs and Wolf Cavalry appeared.

Moreover, not only was the territory's strength growing.

The strength of Han Xing and others was also rapidly enhancing.

Everything was moving in a positive direction.

After finishing all this, Han Xing concluded his busy day.
