I, the Supreme Overlord, Start by Enslaving the Zerg Queen

His eyes still carried confusion and bewilderent, not understanding Charles's words.

He would never get the chance to understand, as those who died under the Godslayer Spear had even their soul marks erased, leaving no possibility of resurrection.

Medusa, Amy, and the others stared blankly at Charles's back.

They hadn't even had time to react before the monster that had put them in such peril was slain by Charles with a single strike.

"So this is Master's current power?" Medusa's eyes sparkled with admiration, her loyalty deepening. Only someone as powerful as Charles was worthy of her allegiance as the Serpent Queen.

"The King... is so strong." Amy's eyes were filled with envy. The invincible strength Charles displayed was exactly what she aspired to achieve.

"Damn monster, you deserved to be killed by the Master for bullying us!" Little Green clenched her tiny fists tightly, her face full of admiration.

Hel's head slowly faded away.

But on the ground, it left behind a fist-sized crystalline object.

Is this... the Heart of the Overlord?!

Charles's heart skipped a beat as he bent down to pick it up.

The moment the Heart of the Overlord touched his hand, he felt an intense chill seeping into his palm.

Immediately after, he sensed a dense aura of death and resentment emanating from it, as if it was filled with Hel's grudges and many tormented souls.

Charles frowned, this was clearly not a normal Heart of the Overlord.

A glint of silver flashed in his eyes.

Eye of Data, activate!

…

Seeing this information, Charles's eyelid twitched. He hadn't expected it to actually be a special type of Heart of the Overlord!

Charles was no stranger to this kind of item.

Both his Zerg territory and Eve's Forest of Elves were special territories of their own kind.

However, they were born with these special territories, while the item in his hand was a tool to transform a territory post-factum.

The key point was, he could use this thing too!

Even though it would waste some of the Heart of the Overlord's power, his Zerg territory was far stronger than an undead territory.

So for him, this was a no-brainer.

The only option was to fuse it.

However, to fuse the Mutated Heart of the Undead, Charles still needed to meet the upgrade conditions.

The latter three conditions were clearly more difficult than the usual territory upgrades. Even Charles had only met the first two at present.

But this was not a big problem.

Once he conquered the Serene Forest, his territory's strength would inevitably skyrocket, making it easy to meet those conditions.

Charles calmed himself and stored the Mutated Heart of the Undead in his system space.

Next, he needed to deal with the battlefield.

Looking at the ground littered with the bodies of Zerg soldiers, Charles felt a pang in his heart. Every soldier here had been painstakingly built up with resources.

"Damn it, if I had known, I wouldn't have let that guy die so easily!"

Charles gritted his teeth, then sighed deeply.

Ultimately, it was because the Zerg soldiers he had were too low-level, mostly bronze and silver units.

If they had been gold-level soldiers, even if Medusa and the others couldn't defeat Hel and his undead army, they could have used battle tactics to hold him off, minimizing the Zerg army's losses.

But there was nothing he could do about it, the resources in the beginner's village were limited. The fact that Charles had managed to raise such a large Zerg army was already thanks to leeching resources from other Overlords. There simply weren't enough resources to cultivate a gold-level army.

"I need to make more money." Charles thought, clenching his fist. He began to plan how to get those Overlords to willingly hand over their resources to him to make up for this loss.

At that moment, Catherine entered the valley with her army.

Charles instructed her to take stock of the losses, fearing that if he did it himself, he would have a heart attack.

Medusa, Amy, and Little Green, noticing Charles's furrowed brows, felt ashamed.

If it weren't for them, the Master wouldn't be so distressed.

Medusa lowered her head and said, "Master, don't be angry. It's all my fault. If it weren't for my orders, the army wouldn't have come here, and we wouldn't have suffered such losses."

"It's not Medusa fault. I agreed to it as well." Amy said, biting her lip, her eyes filled with guilt.

"And me too." Little Green added, lowering her head.

Charles's frown eased a bit as he asked, "Tell me what happened."

He wasn't actually angry, because he knew that Medusa and the others wouldn't have deviated from their path without a good reason.

Medusa, full of self-reproach, explained, "While we were on the road, I found some untreated raw Mana Stones on a few dark creatures nearby. I suspected there might be a low-grade mana stone vein around here and decided to check it out. That's when we encountered the undead army."

Amy continued, "Little Green and I weren't far away. When we heard the commotion, we rushed over and saw Sister Medusa fighting a group of undead creatures. So, we thought to bring the army to help. But we didn't expect there to be so many undead creatures. By the time we realized it, we were already surrounded..."

At this point, Amy trailed off, because what followed was Little Green calling Charles for help.

The three of them hung their heads like children who had been caught doing something wrong. However, Charles's attention was not on them at all at that moment.

He was deep in thought.

Could there really be a Mana Stone Vein here?

Mana Stones were one of the fundamental currencies in the Continent of Overlords, containing highly pure magical energy. Such stones were virtually unseen in beginner's villages because no one would trade Mana Stones with a bunch of rookie Overlords, let alone raw Mana Stone ore.

So, there were likely two possibilities.

One was that the previous guy had set a trap, deliberately luring Medusa and the others here.

The other was that there really might be a Mana Stone Vein here!

At this point, Charles understood why Medusa had come straight here with her people.

If it were him, though he might have been more cautious, he would have definitely come to check it out too.

After all, a Mana Stone Vein was incredibly valuable.

Even the lowest grade Mana Stone Vein could produce nearly 500 million Mana Stones.

That might not seem like much, but considering the purchasing power of low-grade Mana Stones on the Continent of Overlords, 500 million Mana Stones could easily buy a medium-sized city and the surrounding area, roughly equivalent to one-sixth of Blue Star.

And that's just for low-grade Mana Stones. If it were mid-grade, their purchasing power would be 100 times higher, and for high-grade, it would be 10,000 times higher!

This is because Mana Stones, besides being used for transactions, can also be absorbed and used to create extraordinary items. They are an incredibly scarce resource, even for high-level Overlords.

So, whether there was a Mana Stone Vein here or not, Charles felt it was necessary to search the area.

After all, there was nothing to lose if he didn't find anything.

But if he did find it, he would be fabulously wealthy overnight!

Charles didn't delegate the search to others, instead, he closed his eyes.

"Buzz!"

Read first on mp-yr.

Immediately, a vast wave of mental energy radiated outward from him as the center.

After reaching the fifth tier, not only had Charles's combat power increased, but his mental energy had also been enhanced.

As the Zerg Overlord, his mental energy was already extraordinary. Upon reaching the fifth tier, it had grown significantly stronger.

Now, Charles's mental energy had a sensing range of several kilometers, more than enough to probe this valley.

As his mental energy spread out, the terrifying pressure caused Medusa and the others to turn pale, feeling as if a massive mountain was weighing down on them.

However, the pressure vanished almost immediately, as if it had never been there.

"What terrifying mental energy!" Medusa said with lingering fear.

As the Queen of the Serpent race, her mental energy was already stronger than that of other races. But in front of Charles, she felt like a mere child.

Amy looked at Charles's handsome profile, her eyes filled with a mix of admiration and envy.

It seemed as though she made some kind of decision in her heart, her beautiful eyes showing a resolute determination.

Amy remembered the King had once said that if she showed complete loyalty, he could enhance her power.

She had thought about it for a long time, not knowing how to show one hundred percent loyalty to the King.

However, just a few days ago, while chatting with Catherine, Catherine had given her a suggestion. Although the idea was somewhat embarrassing and seemed only applicable to herself…

It had inspired Amy to come up with a clever approach.

She had been preparing to try it over the past few days.

At that moment, Charles suddenly opened his eyes.

"I actually found it!" He exclaimed, clenching his fist tightly, his eyes filled with joy.

In a corner of the valley underground, his mental energy had clearly detected something unusual. Though it was faint, he was certain it was the aura of Mana Stones!
