78: Chapter 78 The Source Crystal Modification is Too Powerful!

Xu Qin, who could finally rest for a moment, walked over to the heavy Bone Transport Cart parked on the Combat Readiness Platform.

Inside the cargo bed, a small pile of orange crystal fragments lay quietly.

Those were the eternal source crystals that the Troglodytes had just chiseled off.

The quantity wasn't large, but this was the first time Xu Qin had personally touched the main body of the ore vein.

He walked over and picked up a fist-sized orange crystal from the cargo bed.

It felt warm to the touch, with light flowing within it.

The command panel popped up with the complete description.

Xu Qin stared at the description, unconsciously tightening his grip on the crystal.

Then he turned his head to look at the small pile of eternal source crystals, and then back at the long list of modification options on the panel.

"Good grief! I knew you were strong, but I didn't expect you to be this strong!"

Xu Qin put down the crystal and walked quickly toward the various functional zones.

The Watchtower and Magic Zone, which were previously upgrading, had all reached Level 5.

Only the Lords Hall was still in the middle of upgrading.

Xu Qin walked to the control panel of the Forging Area and opened the main interface.

Beside the [Upgrade] button, an orange [Modification] button had appeared.

Xu Qin clicked it.

The interface expanded, and a dense list of material requirements appeared before his eyes.

[ Forging Area · Source Crystal Modification ]

[ Modification Level: 1→5 (Because the Forging Area was formed by merging the original Forge and Workshop, the modification requires reshaping from the underlying structure of the two Level 1 buildings) ]

[ Required eternal source crystal: 48,000 units ]

[ Modification Time: 72 hours ]

[ Post-modification Effect: Unlocks Legendary-grade equipment forging... ]

"How much! Forty-eight thousand?"

Xu Qin hurriedly opened the transport vehicle interface to confirm the crystal quantity.

[ eternal source crystal: 1,274 units. ]

Hiss...

Xu Qin took a deep breath. "Now I finally know why the Forging Area is so expensive. It's a merger of two buildings, and it's being reshaped from the ground up."

He clicked on the next one... the Hall of Valor.

[ Hall of Valor · Source Crystal Modification ]

[ Required eternal source crystal: 35,000 units ]

Then he looked at the Magic Zone.

[ Magic Zone · Source Crystal Modification ]

[ Required eternal source crystal: 32,000 units ]

Xu Qin's emotions gradually stabilized.

He checked them one by one, until he clicked on the Ring-shaped Bone Wall within the defense system options.

[ Ring-shaped Bone Wall · Source Crystal Modification ]

[ Modification Description: The Ring-shaped Bone Wall has a total length of 1,640 meters, including the main Bone Wall body, 8 turrets, and the Dark Erosion Plating system. Modification requires segment-by-segment source-crystalization and reshaping of the entire length of the Bone Wall. ]

[ Required eternal source crystal: 167,000 units ]

How much! One hundred sixty-seven thousand?

Xu Qin closed the panel and opened it again.

"Units, tens, hundreds, thousands... Good grief, it really is one hundred sixty-seven thousand?"

He turned and walked toward the Lords Hall.

On the control panel at the front of the hall, there was also a [Modification] button, but it was grayed out.

After clicking it, a prompt popped up: [The Lords Hall is currently in an upgrading state. Modification operations cannot be performed until the upgrade is complete.]

Xu Qin closed his eyes.

He had just been thinking that a daily output of 100,000 mineral essences was pretty fierce.

Now, looking at these numbers...

"Just one Bone Wall costs one hundred sixty-seven thousand."

"Plus the Forging Area, Hall of Valor, Magic Zone, Energy Zone, Watchtower, and the Lords Hall itself..."

Xu Qin did a rough calculation in his mind. Adding it all up, it was roughly between 500,000 and 600,000.

And the eternal source crystal wasn't mineral essence; it was the actual main body of the ore vein.

Mineral essence was decomposed from the remains of guardians and could be farmed infinitely.

But the eternal source crystal had to be chiseled off the ore vein wall piece by piece.

"No rush, let nature take its course. If I can find one ore vein, I can find a second one."

"And... the quantity of this current ore vein looks quite large."

Xu Qin closed the interface and walked back to the Underground Space.

He couldn't be in a rush to mine the ore vein.

The top priority was to first raise the combat power of his units a bit more.

Only when his team was strong enough to clash head-on with the guardians would it be the right time for large-scale mining.

Even if he rushed in to mine now, he didn't know what was hidden in the core area.

If half of his Undead Army died, that would be painful.

Therefore, farm first; he needed to be patient.

For the time that followed, Xu Qin threw all his energy into the mineral essence workshop.

Ten pits, assembly line operations.

Tian Ming and Chuan Yun led the Ranged Troops back and forth, and the time taken for each round of kills became shorter and shorter.

Remains moved out, decomposed, strengthened. Repeating the cycle.

By evening...

Ding! [ Lord Level up! 22 → 23! ]

Ding! [ Talent ' War Gift ' Level up! 10 → 11! ] [ War Gift LV.11: Upon combat settlement, all loot quantity × 12! ]

Xu Qin looked calmly at the popped-up panel and let out a long breath.

Finally leveled up.

Now, leaving 10 remains in each pit and killing them after resurrection directly dropped 120 remains.

Efficiency had increased by another notch.

"Continue!"

The Undead Race had no fatigue value.

One thousand nine hundred and seventy Ranged Troops didn't need to eat or sleep either.

The Undead never stop!

The next three hours.

Ding! [ Lord Level up! 23 → 24! ] Ding! [ Lord Level up! 24 → 25! ]

Xu Qin checked the time. From when he started farming the ore to now, it had been less than eight hours.

He had leveled up three times in a row. War Gift had even leveled up to 13. Output increased to fourteen times!

Xu Qin suppressed a smile and opened the hero panel.

Tian Ming had rushed from Level 22 all the way to 30, leveling up eight times in one go.

Although the experience requirement for Epic quality was high, he couldn't handle how many were being killed.

Ten pits could cycle through dozens of rounds per hour; the experience from tens of thousands of guardians was all poured in.

Moreover, Chuan Yun had also leveled up to 21.

"White-tier heroes level up so fast." Xu Qin remarked with emotion.
