Chapter 724: I Come to Guard

Lei Ming unleashed a burst of Blood Thunder, blasting the entire tomb chamber clean, leaving no corner untouched.

Whether or not the Yin Soul was discovered, they blasted the chamber once with Blood Thunder, leaving it a wreck.

Ye Liuyun, although he sealed the Yin Soul, did not strike the Mourning Bell again.

He wanted to ask the Yin Soul what the layout here was really about.

But for now, deal with the Mysterious Dark Azure Flame first, otherwise the Nether Ghost Fire would easily be assimilated.

Ye Liuyun sent Lei Ming and Long Nv as Protectors, while he entered the Xuan Kong Shi, using True Essence to suppress the eruption of the Mysterious Dark Azure Flame, releasing it bit by bit for the Nether Ghost Fire to absorb.

Two days later, Ye Liuyun's True Essence was nearly exhausted, and the Nether Ghost Fire finally completed the absorption, almost being assimilated.

This was still Ye Liuyun, while depleting True Essence, using the Primordial Spirit Secret Technique to draw spiritual energy from the Spirit Stone, just barely coping.

"Good fellow! I almost let that Yin Soul ruin my Nether Ghost Fire!"

Ye Liuyun finally let out a breath.

Sensing no abnormality outside, he immediately continued to consume the Spirit Stone to replenish True Essence.

Only after fully restoring True Essence did he emerge from the Xuan Kong Shi.

"Big brother, you finally came out! It's so gloomy in here, and without you I even feel a bit scared!" Lei Ming, seeing him emerge, instantly perked up.

"They're just Souls, nothing to fear!" Ye Liuyun comforted him briefly, then used Divine Sense to start communicating with the Yin Soul.

"You can't kill me!" the Yin Soul replied outright.

"Why?" Ye Liuyun pressed.

"Why so many questions? Anyway you can't go in; entering would be death! You also can't kill me, otherwise…"

At that point, the Yin Soul fell silent again, closing its mouth.

"Otherwise this tomb would be breached? The Alien Evil Artifacts inside would escape?" Ye Liuyun added.

"You know and still ask?" the Yin Soul muttered displeased, then grew curious: "Huh, how did you know that?"

Ye Liuyun ignored its question and directly made his demand: "I want your Mysterious Dark Azure Flame!"

"Impossible! This Mysterious Dark Azure Flame is the key to guarding this place. Without it, we can't stop those Alien Evil Artifacts!" the Yin Soul shouted anxiously.

"If you won't give it, I'll take it myself! Here, I will guard!" Ye Liuyun said calmly, pulling out a Divine Artifact Fragment, ready to strike the Mourning Bell.

"Impossible! There's an Alien strongman inside; if you go in, it's certain death! This tomb will never be able to block them again!" the Yin Soul persisted.

He thought that with Ye Liuyun's cultivation level, entering would be death! Yet he didn't know that Ye Liuyun's real Trump Card wasn't his level, but those artifacts.

"Fool!"

Ye Liuyun muttered a curse in his heart, flicked his finger, and the Divine Artifact Fragment rang the Mourning Bell.

Dong!

The Mourning Bell echoed throughout the tomb chamber.

The Yin Soul was instantly shattered, leaving only a wisp of blue flame pulsing inside the Mourning Bell.

"Mysterious Dark Azure Flame Origin!"

Ye Liuyun was overjoyed upon seeing it.

However, he dared not absorb it all at once, only taking it in bit by bit.

At that moment, within the tomb, a Foreign Tribe Yin Soul, perhaps sensing the disappearance of the tomb's guardian Yin Soul, immediately sent another Foreign Tribe Yin Soul to scout.

"Seeking death!"

With a "Hoo" sound, Ye Liuyun unleashed a strand of Nether Ghost Fire, sealing the tomb's door to prevent them from breaking in.

"Aoo, aoo," a few shrieks, then sent those Yin Souls back down.

Ye Liuyun's Nether Ghost Fire, after absorbing the blue flame these days, had grown considerably stronger. Its rank was already high, so its deterrent against Yin Souls was no weaker than the guardian's.

As long as no overly strong Foreign Tribe attacks, it should hold.

Ye Liuyun didn't rush to go deeper; instead he had Lei Ming and Long Nv watch the Nether Ghost Fire at the tomb entrance, while he took the core of the Mysterious Dark Azure Flame into the Xuan Kong Shi to refine it.

According to the Yin Soul, there are even stronger Foreign Tribes inside. Even with artifacts, he must boost his own strength as much as possible before entering.

Ye Liuyun spent nearly three days inside the Xuan Kong Shi to fully refine the core of the Mysterious Dark Azure Flame.

Now his Nether Ghost Fire is incomparable to before, more than half stronger than it used to be.

Though still far behind the Golden Crow Holy Fire, at least for the upcoming tomb explorations he feels more confident.

"Let's go, we continue."

Ye Liuyun called out to Lei Ming and Long Nv, then withdrew the Nether Ghost Fire at the tomb entrance and plunged straight into the Alien Evil Artifact tomb.

They discovered that after that chamber, the preceding Yin Souls were all Alien Evil Artifacts, not a single human Yin Soul. Moreover, although few in number, these artifact Yin Souls were relatively powerful.

Ye Liuyun walked from the outside inward, sparing no Yin Soul he passed.

This passage was specially designed, with no side routes in the middle, so he didn't need to be distracted by anything else.

"The design of this passage is just perfect for defense!" Ye Liuyun thought, admiring the tomb's designer.

The Yin Souls he slain were used for him and Lei Ming to absorb, strengthening their own Souls.

Ye Liuyun's newly cultivated Soul needed energy to replenish.

After Lei Ming absorbed a portion, he felt the growth was negligible and grew lazy to continue absorbing, so he gave the rest to Ye Liuyun.

With each tomb chamber he passed, Ye Liuyun paused to steady the newly strengthened Soul, continuously hammering and solidifying it with Blood Thunder and Nether Ghost Fire, then proceeded onward, treating this place as a treasure ground for Soul cultivation.

Soon, Ye Liuyun and his group attracted powerful Evil Artifact Yin Souls.

Yet the Nether Ghost Fire's suppression of Yin Souls was highly effective. Even when facing those of higher realms, a single blaze could incinerate them.

No matter how strong these Yin Souls were, there was nothing he could do with them. He could only push forward chamber by chamber.

After walking for a while, Ye Liuyun stored Lei Ming and Long Nv into the Storage Ring.

The Yin Souls now appearing were too strong; the two of them could no longer contribute, and Ye Liuyun still had to consider their safety, so it was better to let them return to rest.

"When this place was first invaded, we still don't know how those Alien Evil Artifacts were eliminated. Judging by the current situation, they are far stronger than humans!"

Ye Liuyun walked while also imagining what the scene was like when this place was invaded by the evil artifact.

At that time, the Alien Evil Artifact likely had the advantage, one-sidedly suppressing the Human Race Martial Cultivators.

Just then, he suddenly received a message from the Corpse-Eating Worm King; they had already explored to the deepest part of the tomb.
