11: Three in one! Is your air defense tower as powerful as my frost rocket?

Day four, early morning.

The world, it seemed, had died overnight.

The air was no longer merely silent; instead, a thicker, colder malice permeated it, as if countless invisible eyes were lurking behind the gray mist, peeking at every lonely fortress.

The halo of the novice protection period had vanished.

Lin Feng opened his eyes, not a trace of sleepiness in them, only a sharp, calm gaze that seemed to penetrate everything.

He didn't touch the breakfast, which had already been upgraded to a sandwich and milk.

In the face of a bloody war that could erupt at any moment, any hint of slackness was a blasphemy against life.

With a thought, a light blue panel unfolded before his eyes.

【Gold Coins: 4600】

【heavy oil: 500】

A string of cold numbers, yet they seemed to contain a prairie fire.

This was his greatest confidence in daring to face this cruel new world!

The invisible pressure brought by the SS-rank talent 【Hedge Fund】 owner yesterday had now transformed into the best fuel for him to become stronger.

Others' finish line was merely his starting point.

His gaze, like a predator locking onto its prey, was fixed on the ladder on the panel that led to a higher dimension.

【Upgrade Main Base to Level 4: 2000 Gold Coins】

“Upgrade!”

The moment these two words were silently uttered in his heart, the entire fortress platform violently shook, letting out an unbearable roar!

Rumble—!

A golden pillar of light, thicker and more solid than any before, shot into the sky like a spear of divine punishment, tearing open a massive gap in the eternal gray sky above the fortress!

Sunlight!

Though only for an instant, that long-lost, warm light truly shone down!

The platform beneath his feet expanded wildly, its area nearly doubling!

On the surface of the thick city walls, the strange crystals completely melted, transforming into a visible energy halo that flowed with a pulsating light, enveloping the entire fortress.

【Congratulations! Your Main Base has been upgraded to Level 4!】

【Wall Durability Increased: 3000 -> 4000】

【Wall Trait: Energy Regeneration -> Energy Shield (The city wall will gain an additional shield value equal to 20% of its maximum durability, which will slowly recover over time)】

【Defense Tower Slots: 6 -> 8】

【Resource Building Slots: 4 -> 5】

【New Building Unlocked: Spell Factory】

【New Building Unlocked: heavy oil Drill】

Accompanied by an epic system prompt, a mysterious tower with a huge blue crystal embedded at its top slowly rose from the open ground of the fortress.

【Spell Factory】: Can consume time to create powerful spells, personally cast by the Lord in battle.

【Currently Unlockable Spells】: 【Arrow Volley】 (Creation Time: 20 minutes. Maximum Spell Storage: 1.)

Lin Feng’s eyes flickered.

A trump card that could only be used once per battle.

This meant it had to be used at the most critical moment, to turn the tide of battle and deliver a decisive blow!

His gaze quickly moved to another new building.

【heavy oil Drill】: Produces 10 heavy oil per hour. Construction Cost: 200 Gold Coins.

The food of heroes.

The key to his becoming stronger.

Lin Feng’s brow furrowed slightly.

Only one resource slot was added, making it five.

And his current four slots were all filled with the highly profitable 【Refined Gold Mine】.

Should he continue to maximize gold production, or allocate a precious slot to invest in the future?

This thought lasted only a tenth of a second before he completely cut it off.

Only children make choices.

He wanted it all!

“Purchase two 【heavy oil Drill】.”

【Gold Coins x400 consumed.】

“In the fifth resource slot, build, and then… synthesize!”

Two phantom buildings with black drilling rigs had just appeared when they were instantly pulled and merged by an invisible force, transforming into a deep black light that violently fell back into one of the slots!

【Synthesis successful! You have obtained a rare building — Advanced heavy oil Drill!】

【Advanced heavy oil Drill】

Quality: Blue (Rare)

Effect: Produces 20 heavy oil per hour.

Footprint: 1 Resource Building Slot.

After completing all this, Lin Feng’s economic panel became a perfect ratio of four 【Refined Gold Mine】 and one 【Advanced heavy oil Drill】.

80 Gold Coins per hour, plus 20 heavy oil!

Now, it was time to make up for his only weakness.

Anti-air!

He never liked to entrust his fate to the mercy of enemies who couldn't fly.

“Unlock the 【Anti-Air Rocket】 blueprint.”

【Gold Coins x400 consumed.】

“Purchase three 【Anti-Air Rocket】.”

【Gold Coins x1200 consumed.】

Three silver-white rocket launch platforms, full of a stark sense of technology, rose from his three vacant defense tower slots.

“Select three 【Anti-Air Rocket】, synthesize!”

【Ding! Three identical buildings detected. Proceed with identical synthesis?】

“Yes!”

This time, it was no longer a simple fusion!

Three dazzling silver lights shot into the sky, intertwining and swirling, actually forming a rapidly rotating energy vortex!

At the center of the vortex, a frosty blue light suddenly exploded, transforming into a blue pillar of light, even more brilliant and sharper than before, crashing down like divine punishment!

The light dissipated.

An even larger, more complex anti-air matrix, composed of three independent launch bays, appeared in the original position.

It stood there silently, frosty blue energy patterns slowly flowing on its surface, exuding a deadly chill capable of freezing souls.

【Synthesis successful! You have obtained an excellent building — Triple-Barreled Frost Rocket Silo!】

【Triple-Barreled Frost Rocket Silo】

Quality: Blue (Excellent)

Attack Power: 150

Attack Speed: 1 second / shot

Range: 100 meters

Special Effect: 【Frostbite】 — Flying units hit will be afflicted with a frostbite effect, reducing movement speed and attack speed by 30%!

Looking at these terrifying panel statistics, Lin Feng’s last trace of worry about air defense completely vanished.

He glanced at his Gold Coin balance.

【Gold Coins: 1400】

A series of operations had cost him most of his savings.

Inside the 【Institute】, new blueprints had already been unlocked.

【Mage Tower】: Unlock cost 500 Gold Coins. (Can deal magic damage that ignores armor)

【Machine Gun Tower】: Unlock cost 500 Gold Coins. (Has extremely high attack speed, good at clearing low-health units)

Lin Feng’s pupils contracted slightly.

The words “ignores armor” immediately made him think of that clumsy P.E.K.K.A. Superman from last night.

This was definitely a powerful weapon for late-stage assaults.

But after a moment of contemplation, he still forcibly suppressed the urge to unlock it immediately.

Gold Coins were the most flexible trump card in this world.

Before unknown dangers arrived, maintaining sufficient adaptability was far more important than simply stacking defenses.

Having completed all this, he finally turned his gaze to the 【Hero Altar】, which had already accumulated enough “food.”

No matter how strong a fortress was, it was ultimately an external object.

Only power held in one's own hands was eternal truth.

【Current heavy oil Reserves: 500】

He immersed his will into it, and the Barbarian King phantom holding a great axe seemed to sense his gaze, letting out a silent roar.

【Hero: Barbarian King (Level 1)】

【Required to upgrade to Level 2: heavy oil x100】

“Upgrade.”

【heavy oil x100 consumed, Barbarian King level increased to Level 2!】

【Required to upgrade to Level 3: heavy oil x200】

“Continue to upgrade.”

【heavy oil x200 consumed, Barbarian King level increased to Level 3!】

Lights flashed one after another, and the Barbarian King phantom's physique visibly became more robust, with a faint reddish glow emanating from the great axe in his hand.

【Hero: Barbarian King】

【Level】: 3

【Attack】: 80

【Health】: 800

【Skills】: None

In one go, he converted all the spoils of war obtained last night into the hero's immediate combat power.

Lin Feng slowly exhaled, his gaze sweeping over his newly renovated fortress.

An economy that produced vast amounts of gold daily.

Defenses capable of both ground and air combat.

A hero poised for action.

A fortress of war, solid as gold, had already begun to take shape.

Meanwhile, the regional channel was still immersed in the endless panic and suspicion brought by the activation of PVP.

The true hunter had already sharpened his claws while the flock wailed for survival.
