Wizard: My skills can be upgraded indefinitely.

The renowned author, Seven Degrees of Sunset Red, has joined Cola Novels with his new work, "Wizard: My Skills Can Break Through Infinitely!"

Inside the Wizard's Tower, Ian received a message from Azshara.

"If the Zerg invade, the main battlefield will be near the Purple Mist World, which means this will be the first line of defense."

There are super-energy crystals here, an irresistible temptation for the Zerg. The next one to come will probably not be a level 5 mother hive.

"Alright," he murmured to himself, his eyes gradually brightening.

"Let's use the Zerg to test just how powerful the Tower of Eternity is with the addition of the super-energy crystal."

Consciousness descended upon the Zerg plains.

Kerrigan was lying beside a newly built hatchery, her whiskers gently brushing against the biomass slurry inside.

The dark gold star patterns on the carapace are more intricate than before.

After absorbing the associated mineral, although she hasn't broken through to level five yet, her soul aura is much stronger than before.

"Master!" Kerrigan immediately raised her head, her eyes sparkling with anticipation, as she sensed Ian's presence.

Without wasting any words, Ian directly ordered: "The mass troop production strategy needs to be adjusted."

"From now on, cease production of low-tier units and focus all efforts on producing tier 3 and 4 units."

Those low-level units cannot survive in the void and are currently of no use.

Kerrigan's whiskers paused slightly, a hint of confusion flashing in her compound eyes.

"Master, if we don't produce drones... mining efficiency will drop significantly. Although they are weak in combat, their digging and transportation efficiency is the highest."

Ian interrupted her: "There won't be any monsters stopping us anymore, and that little bit of ore won't be mined out for long."

"Also, all the associated purple ore collected should be handed over to me for distribution and use, and half of the super energy crystals should be used to mass produce troops."

"In the coming days, I want to see a Zerg army capable of fighting in the void."

Kerrigan's eyes lit up. "Yes, Master!"

"With enough super-energy crystals, my production efficiency can increase by more than five times!"

For the next three days, the world of purple mist fell into an eerie calm.

The magical beasts that had originally roamed around the mines retreated into the depths of the forest under the control of the world's will.

They no longer attack the Zerg, and even actively avoid the mining forces' activity areas.

In the meditation room, a small bottle of purple liquid floats, viscous as honey and crystal clear as jade.

This is the [Purple Soul Potion] that Ian concocted by further refining the associated ore and combining it with his own potion-making skills. Its purity is more than three times higher than the original powder.

A glint of anticipation flashed in Ian's eyes. He picked up the medicine and drank it down in one gulp, where it exploded in his stomach.

Transforming into billions of tiny purple light spots, they flowed along blood vessels, meridians, and energy channels to every corner of the body.

Ultimately, they converged in the depths of the spiritual sea, causing the dual cores of the sun and moon to tremble simultaneously.

The sun's core emitted a fiery golden-red light, while the moon's core flowed with a cool, silvery-white glow.

Ian felt his soul growing, not in size, but in essence.

A tingling, numbing sensation ran through my soul, along with a strange sense of satisfaction.

Ian closed his eyes and activated the [Sun and Moon Soul Sacrifice Scripture] with all his might, causing the dual cores of the sun and moon to rotate faster and faster.

The surrounding super-energy crystals emitted a faint light, and the energy escaped, being frantically devoured and refined by the dual cores.

Lines of writing appeared at the corner of his eye.

[Dual-core growth rate: 10%, 11%, 12%...]

He was fascinated by the feeling of rapidly becoming stronger, but he remained conscious.

He spared a sliver of his attention to constantly monitor the outside world.

On the Zerg plains, Kerrigan is massing troops, with new hatcheries being built one after another, filled with viscous biomass slurry.

These slurries contain a large number of super-energy crystal fragments, which are slowly dissolved in the biomass slurry, releasing pure, attribute-free energy that is frantically absorbed by the insect eggs in the pool.

The purple hydra that used to take three days to mature now only takes half a day.

The spore anti-air tower, which originally took five days to form, can now mature in less than a day, demonstrating the importance of super crystals to the Zerg.

Kerrigan lay prone in the middle of the plain, her massive body trembling with excitement.

The body's biological factories are operating at full capacity, with new eggs being born from the conditioning chamber every second.

"Master, the effects of the super crystal are amazing!" Her thoughts were filled with almost manic joy.

"At this rate, my army can expand a hundredfold in just three months!"

Ian nodded to himself and continued to cultivate with all his might.

Time passed slowly amidst training and preparation for battle.

A month later.

Inside the meditation room, Ian slowly opened his eyes, and the phantom image of the Sun and Moon dual cores flashed by.

He raised his right hand, and a faint purple light slowly condensed—this was the power of his soul.

Previously, although Ian could manipulate soul power, he was not able to materialize it independently.

Now, he can condense his soul power into a physical form, and his essence has begun to undergo a qualitative change.

With a slight thought, Ian brought up the panel data.

[Dual-core growth rate: 35%]

[Realm: Mid-Morning Star]

In just one month, the growth rate increased by 20%, and the level also entered the middle stage.

This speed is extremely rare in the history of the Wizarding Alliance.

He could clearly feel that after taking the [Purple Soul Potion], his soul's origin had expanded by about half.

But he is far from reaching his limit and still has a lot of room for growth.

"The effects of the associated minerals are even better than expected."

Ian walked to a corner of the meditation room and picked up a fist-sized super-energy crystal.

"Tower Spirit, begin filling the energy storage pool."

"Yes, open the main energy channel and connect to the void energy pool..."

Inside the Tower of Eternity, a thick silver pipe slowly opened.

The inner wall of the pipe was engraved with dense runes, each one glowing faintly.

Ian puts the super-powered crystal into the pipe.

The energy storage markings on the pool wall began to rise rapidly: 10%, 20%, 30%...

"Tower Spirit, prioritize optimizing the main cannon's return path."

Replacing the runes with super-energy crystals will correspondingly increase the load on them.

"Okay, Void Annihilation Cannon design blueprints retrieved, optimization to begin..."

The tower spirits began operating at full power, with countless runes constantly being optimized and recombined, and new rune arrays beginning to grow on the original foundation.

Three days later, the optimization was completed.

Ian stood in front of the crystal wall in the control room. "Test the main cannon's continuous firing, keeping the power at 10%."

"Yes, the Void Annihilation Cannon is beginning to charge..."

The silver spikes at the top of the tower slowly lit up, charging at an astonishing speed.

Swoosh! A gray beam of light shot out, piercing through the void.

Then came the second shot, the third shot...

After ten consecutive shots, the rune array inside the tower remained as stable as a rock, showing no signs of collapse.

Ian's face showed satisfaction. Although it wasn't at full power, the stability of the runes had been tested.

"It's done..." he muttered to himself, a cold glint in his eyes.

"From this day forward, the Void Annihilation Cannon will be upgraded to a conventional weapon."

For the next two months, Ian trained while monitoring the Zerg's troop buildup.

Kerrigan is extremely efficient; she has an instinctive love for mass-producing units.

With half of the super-energy crystals as energy, her bio-factory never rested for a moment.

Batch after batch of insect eggs are born from the preparation chamber, and batch after batch of new units hatch.

The number of purple hydralisks surged from the initial two hundred to five thousand, while the number of void black bees increased to one thousand five hundred.

The number of Spore Anti-Air Towers increased from five to one hundred, and the number of Tier 3 Zerg reached a scale of one million!

On the Zerg plains, a dense, dark mass of Zerg swarmed.

Kerrigan lay in the middle of the plain, her massive body now even larger than before.

The six pairs of wings on its back became more solid, and the purple patterns on its surface flowed slowly as if they had come to life.

Her aura was already incredibly close to level five, just one step away!

"Master~~" Her thoughts were filled with a devout longing.

"I can feel it. That threshold is right in front of me. Just give me a little more... just a little bit of by-product mineral!"

"I can get over it..."

Ian chuckled slightly; as Kerrigan grew older, she became more and more aware of the changing nature of people's hearts.

But at this moment, deep within Kerrigan's soul, that constraint was indeed loosening.

"Taling, take 100 grams of the purified by-product ore."

"Yes, Master, activate special storage unit, retrieving..."

A few seconds later, a small ball of purple powder appeared in Ian's palm, containing an even purer and more concentrated essence of soul.

With a thought, Ian sent the powder to Kerrigan.

"I will help you one more time. After the breakthrough, you will be a true level five mother nest."

Kerrigan's eyes widened suddenly as she stared intently at the purple powder in front of her, her body beginning to tremble.

"Yes, Master! I will always be your most loyal servant..."

She opened her small mouth and swallowed the powder whole, causing a surge of immense spiritual energy to explode within her body.

Kerrigan's body erupted with a dazzling purple-gold light, and her carapace began to peel off and regenerate.

The six pairs of wings on its back extended and evolved wildly, and its aura began to rise.

Ian sensed through the soul contract that Kerrigan would be able to truly break through to level five in about two or three months.

"With a level 5 mother hive and an infinitely powerful wizard tower, we finally have a sliver of power to protect ourselves."

Another month has passed.

In the meditation room, Ian sat cross-legged in the center, absorbing the super energy crystal with all his might.

The growth rate of the Sun and Moon dual cores has reached 50%, and they will soon reach the late stage of Morning Star. The origin of the soul has been expanded by one time.

Just then, the tower's alarm suddenly went off.

"Master, large-scale void fluctuations have been detected at the outer edge of the Purple Mist World!"

"Approximately eight million kilometers from this world, the quantity... is countless."

Ian slowly stood up, his eyes flashing with a cold light.

"It's finally here!"
