The deeper you go, the higher the grade of the refined iron becomes.

In fact, mines are usually dug by humans, but this vein of mine has no trace of human footsteps, and has obviously been occupied by the Mountain Crystal Treasure Spider.

So these so-called mines are actually passageways dug by the Treasure-Hunting Spiders to facilitate their consumption of refined iron.

Some areas are very wide, while others are so narrow that they seem to only allow one or two treasure-hunting spiders to pass through.

Jiang Wuyuan used the Breath Concealment Technique to suppress his aura, and then slowly delved deeper into it.

If you encounter a place you can't get through, use your flying sword to clear the way.

—This sword control technique is not only excellent for mining, but also very useful for clearing paths.

After walking for nearly three hours, we still hadn't reached the end.

His soul was severely restricted in the vein mine, perhaps due to the chaotic magnetic field, to the point that Jiang Wuyuan did not know how much further he had to go.

With a single sword strike, Jiang Wuyuan cleaved a charging fourth-tier treasure-hunting spider in two, caught the falling blood crystal, and looked up into the dark depths of the vein mine, its depths unknown.

After arriving here, the aura of lightning element became noticeably more active.

Jiang Wuyuan was pleasantly surprised.

If a piece of high-grade refined iron with lightning attribute could be found, then Devouring Star could have the same effect as Azure Flame Stepping Song.

This spurred him to keep going.

But soon, Jiang Wuyuan discovered that things were not so simple.

Because these treasure-hunting spiders are gathering.

As we learned from textbooks, the Mountain Crystal Treasure Spider is a social magical beast, and they will choose an outstanding Treasure Spider as their leader.

Could it be that the leader of the Treasure Spiders has already discovered him?

This speculation gave Jiang Wuyuan a headache.

Given the sheer size of the mine, it's hard to say what rank the leader of that treasure-hunting spider might have reached.

If it were someone above the seventh rank, he wouldn't be able to handle them at all right now.

Jiang Wuyuan did not panic, but he also stopped controlling his speed.

I've already collected a lot of low-grade refined iron, so I won't stop until I encounter it again.

The young man used his magic to propel himself forward, his figure sweeping swiftly into the depths of the mine like a gentle breeze.

Flying swords swirled around him, clearing away the mud and corpses blocking his path, and incidentally killing those low-level spiders who were blind to their own mortality and rushed up to their deaths.

Collect some sixth-grade refined iron.

Huh? What's this? Black iron ore?

Its hardness is higher than that of ordinary refined iron.

Good stuff, I'll take it.

Jiang Wuyuan intentionally avoided engaging in combat with the Treasure-Hunting Spider, which allowed him to advance at an extremely fast pace.

At the end of the mine, a huge rock blocked the way, but the aura of lightning element was already extremely strong, as if it was right behind that boulder.

Jiang Wuyuan narrowed his eyes and raised his hand to unleash a sword strike.

boom--

The bluestone was shattered by the powerful sword intent, and Jiang Wuyuan finally saw what the depths of the vein mine looked like.

The surrounding rock walls were covered with oddly shaped pieces of high-grade refined iron.

Above their heads, a purple ore was surrounded by a dense layer of lightning element that looked as if it were about to drip water.

The purple light shimmered brilliantly in the dark environment.

It was actually Xuan Lei Marrow.

A very rare and special mineral containing extremely powerful and violent energy.

As Jiang Wuyuan's eyes lit up, a look of seriousness flashed in his eyes.

Because a massive Treasure-Hunting Spider was lying securely beneath the Profound Thunder Marrow.

Its upper body resembles that of a human woman, while its lower body has a huge, spider-like abdomen and eight long, thin, sharp legs.

Bathed in the energy of lightning, purple patterns appeared on its body, which should have been blood red.

Seventh-order mutated Mountain Crystal Treasure Hunter Spider.

Judging from the aura, it's probably more than just the initial stage.

A direct confrontation would certainly be unwinnable, but it doesn't mean one can't outsmart the opponent.

He absolutely could not miss out on a treasure like the Profound Thunder Marrow.

The commotion from just chopping the bluestone had already attracted the attention of the seventh-tier treasure-hunting spider, and its eight eyes looked in the direction of Jiang Wuyuan.

The instant their eyes met, Jiang Wuyuan felt a strong sense of dizziness.

He quickly circulated the Calm Mind Sword Technique once before he could barely suppress the feeling of his body being out of control.

What terrifying spiritual power!

"Humans." The sixth or seventh tier magical beast could already speak human language. Its voice was hoarse and unpleasant, yet surprisingly alluring. "Since you're here, leave your corpse behind."

I haven't tasted human flavor in a long time.

As soon as it finished speaking, it let out a sharp, long howl.

Jiang Wuyuan frowned, thinking it was an attack targeting the soul, but it wasn't.

Suddenly, swarms of treasure-hunting spiders emerged from all around the rock wall, instantly surrounding Jiang Wuyuan and trapping him completely.

Even so, the boy showed no sign of nervousness.

He held the Star Devourer in his hand, with his flying sword swirling around him. For a moment, his aura was in no way inferior to that of the seventh-tier Treasure-Hunting Spider.

"Go!" the Treasure-Hunting Spider commanded.

The swarms of treasure-hunting spiders all around stirred at the sound.

These are not low-level Treasure-Hunting Spiders; even the one with the lowest cultivation level has reached the level of a fourth-tier magical beast.

But faced with the overwhelming attack, Jiang Wuyuan did not choose to take it head-on.

Clouds drift and expand in the sky!

He took a quick step, and his figure immediately disappeared from the spot.

In an instant, they had already leaped into the sky.

The seventh-tier treasure-hunting spider was furious that this human was still coveting its treasure even at this point.

Its compound eyes stared intently at the tiny insect that it found utterly repulsive, and a powerful surge of law energy erupted from its body.

Lightning Law - Heavenly Thunder Domain!
