Yu Guihai came all the way to the honeycomb stone wall. In front of him was an unfathomable abyss. Opposite the abyss was a huge stone wall. The stone wall was densely packed with many large and small holes, exuding a formidable aura.

A black iron chain extends from here and connects to the stone wall opposite.

This stone wall was so spectacular and weird that even when Yu Guihai saw it again, he still couldn't help but admire it in his heart.

Yu Guihai stared into the abyss, and a dark and cold aura suddenly came out, but now he no longer felt fearful in his heart.

"Haha, very good. Wait for me." Yu Guihai smiled, jumped up, and slid along the black iron chain to the honeycomb stone wall opposite.

"It's the entrance to the cave."

Yu Guihai aimed at a hole located in the middle of the stone wall and drilled in.

The place where the Stygian Silver Mine was discovered is at the entrance of this cave.

Yu Guihai walked quickly in the dark passage, exploring with his spiritual thoughts, constantly comparing the map drawn by Duan Tianya in his mind.

From time to time, I encountered some low-level ghosts on the road, and their breath turned into nothingness just by touching them.

It didn't take long for Yu Guihai to arrive at an underground cave. It was a dead end, relatively remote, inaccessible, and empty.

However, as soon as Yu Guihai came in, he found that this place was not simple.

There are numerous Stygian silver ores deep in the stone wall opposite the entrance.

This kind of ore has the characteristic of automatic concealment, and ordinary people cannot detect the clues.

However, this characteristic has no effect in front of Yu Guihai.

He carefully investigated and immediately discovered that only the opposite stone wall had Stygian silver ore behind it, and there was nothing found in the stone walls in the other three directions.

Yu Guihai didn't hesitate, and immediately grabbed it with his hand, and the hard stone wall on the opposite side suddenly shattered into a huge hole, which was several meters deep into the stone wall.

The newly appeared stone wall is inlaid with several pieces of black ore dotted with silver stars.

It's Stygian Silver Ore.

Yu Guihai waved his hand to put away these Stygian silver ores, and then continued to dig. In his perception, the Stygian silver ores formed a small ore belt, extending beyond his perception. He did not know how long it would be in the end.

The rock wall was very hard, but Yu Guihai dug it with ease. He didn't mind being bored, and just kept digging deeper, just like a pangolin.

Wherever he passed, he put all the Stygian silver ores, regardless of size, into his storage bag. The big ones were like stone rolls, and the small ones were as small as the belly of a finger.

After a long time, Yu Guihai stopped, not because he was tired and wanted to rest, but because the five to six hundred cubic meter storage bag he had specially prepared was full.

Looking back, I saw that the entrance of the cave was deep and quiet, and it was clear that a distance of several hundred meters had been dug.

Yu Guihai thought for a while, expanded the surrounding passages into caves, leveled the ground, took out several rune array bases and placed them everywhere on the ground, and then poured a whole storage bag of Stygian Silver Ore on it.

On the ground.

He waved his hand and cast a spell, and pale yin fire immediately erupted on the ground. These flames were like illusory objects, penetrating directly through the ore and burning fiercely. The large pile of Stygian silver ore immediately began to melt from top to bottom at the same time.

.

Yu Guihai circulates his spiritual power, controls his spiritual thoughts, and controls the magic circle to refine the ore.

Soon after, all the ores that filled the cave disappeared, and a layer of gray-white scum appeared on the ground. In front of Yu Guihai was a silver ore the size of a human head. The silver ore was dotted with countless tiny black spots.

This is the Stygian Silver Ore. Those black spots are not impurities, but just anomalies caused by the Yin Spirit in the Stygian Silver.

Yu Guihai put away the ore and continued mining.

In this way, Yu Guihai was mining and refining the ore at the same time, so that he would not worry about running out of storage bags.

As he went deeper, he found more and more ores, and finally he came to a location surrounded by Stygian silver ores.

"We may have reached the center of the vein."

Yu Guihai was thinking in his mind and grabbed the stone wall in front of him. With a bang, the stone wall collapsed, revealing a huge black hole in front of him. He dug through the stone wall unknowingly.

Yu Guihai's expression changed slightly. His mind kept scanning the front, but he didn't find this cave. There must be something mysterious in it!

He specially probed his spiritual thoughts into the black hole, but it was like facing the void, and he was unable to detect any existence in it.

Huh? No!

Suddenly, his expression changed again. There was clearly some kind of force in the black hole that was interfering with his spiritual thoughts.

Yu Guihai thought for a moment, then reached out and grabbed hard, breaking open all the stone walls around the entrance of the cave. This place was indeed the center of the mine vein, and the reserves of Stygian silver ore were extremely rich. These stone walls were actually made entirely of ore.

The black hole expanded, and Yu Guihai's gaze went directly into the hole. The scene in the black hole finally came into his eyes.

Inside the black hole is a small cave of about ten square meters. The four walls are filled with extremely pure Stygian silver ore, and in the middle of the cave, there is a pillow-sized silver ore.

This piece of ore emits a bright silver light, with countless black dots faintly flashing in the light.

The eyes can obviously see this object, but the mind is completely blank and cannot sense it at all.

When Yu Guihai saw this thing, his color suddenly changed and his face showed ecstasy.

"The Mother of Stygian Silver Ore! It turns out to be the Mother of Stygian Silver Ore!"

The Stygian Silver Ore Mother maximizes the ability of Stygian Silver to shield its own fluctuations, which is why he cannot use his spiritual thoughts to sense this object.

Stygian Silver Ore Mother is a high-level spiritual material that is more precious than Stygian Silver and can be used to make magic weapons.

If you use Stygian Silver to make the Five Fire Ghost Flag, after it is made, it will be a top-grade magic weapon at best. But if you use Stygian Mother Mineral Minerals to make the Five Fire Ghost Flag, you can directly make it into a magic weapon level.

Moreover, this thing itself is highly pure, unlike ores that need to be refined to produce Stygian Silver.

Such a big piece is enough for him. Even if he can't find the remaining two skull flags later, he can use this piece of Stygian Silver Ore to directly make two new skull flags, and there will still be some left.

In addition, this item must be used to upgrade the three skull flags he currently has.

This time, it can be said that the problem of the Five Fire Ghost Flag has been solved. Once digested and absorbed, the power of this set of magic weapons will inevitably increase dramatically, becoming a trump card that he relies on.

Yu Guihai waved his hand impatiently, and a big hand of white light appeared out of thin air, grabbing it towards the Dark Silver Ore Mother.

Bang~

Suddenly, a layer of silver-white light appeared, enveloping the Stygian Silver Ore Mother.

As soon as the big hand of white light touched the light shield, a bright silver light burst out from the silver-white light shield, containing extremely sharp edges. Swish, swish, and with a soft sound, the big hand of white light was cut into countless pieces, which collapsed in the air.

When Yu Guihai saw this, he looked happy and shouted: "Well done!"

He had long since discovered something was wrong. There seemed to be an aura of a powerful ghost in this place. However, due to the concealment properties of the Stygian Silver Mineral Mother and the hiding ability of the ghost, he was unable to discover the ghost's location.

So he acted first and captured the ore mother directly. The ghost was born here and would definitely not watch him take the ore mother.

Sure enough, the ghost took action.

At this moment, a flash of white light spread out, and a golden halo emerged, fiercely attacking the Dark Silver Ore Mother.

Zhizhizhi~

A shrill and weird cry came out, and a silver-white villain emerged from the dark silver ore mother. This villain looked very abstract, with slender hands and feet, and the front ends evolved into sharp blades. There were only three black holes in its facial features.

, ferocious and terrifying.
