Longevity through Upgrading Buildings

Chapter 808: Chapter 336: Miracle Treasure—Lightning Chaser

Yin Corpse Demon Fire!

This was still Ji Yuan’s first time using Yin Corpse Demon Fire in a real fight, so he had no idea what its actual power was.

So he simply mobilized all of the Yin Corpse Demon Fire in one breath.

The density of the flames far surpassed that last test he did in the Cave Mansion.

When the Yin Corpse Demon Fire suddenly descended, Ji Yuan discovered that even the Yin Ghost Array couldn’t withstand it. Even though he was already doing his utmost to control it, the array still got hit by friendly fire.

He hurriedly put the Array Flag away to avoid getting burned himself.

But that Tier Three long-necked Serpent right in the middle of the sea of fire was not so lucky.

When it first attacked Ji Yuan, it even split into four, but now, under the burning of this Yin Corpse Demon Fire…

The three Serpent heads gradually turned into Spiritual Qi and dissipated.

Illusory phantoms.

But in that moment when they besieged him just now, they were real enough to pass for the true body, to the point that even Ji Yuan couldn’t tell which was the real one.

But now…

The remaining one, the true long-necked Serpent, was struggling and roaring nonstop under the burning of the Yin Corpse Demon Fire.

Its entire body was covered by a water-blue barrier of light.

But under this Demon Fire, the barrier lasted for not even a few breaths.

Then it turned into Spiritual Light and scattered.

Immediately after, the long-necked Serpent kept spurting out seawater, but since this Yin Corpse Demon Fire could burn in seawater to begin with, how could it fear seawater?

On the contrary, the surging seawater only made the Yin Corpse Demon Fire burn even more fiercely.

Demon Fire burned, leaving nowhere to hide.

In barely the time of a few breaths, the Serpent’s four claws, along with its abdomen, had already been set alight, and the Demon Fire began to burn its body.

“Roar—”

The long-necked Serpent’s roars grew more and more miserable.

Its body twisted and thrashed; it even saw Ji Yuan watching the show from afar. It wanted revenge, but under this Demon Fire, it couldn’t even escape with its life, much less talk of revenge.

In the end it only struggled in place a few more times.

With its four claws burning, it couldn’t even stand, and could only roll around on the ground.

Like this, after a few more breaths, it couldn’t even turn over.

Lying on the ground, many parts of its body already showed bare white bone.

Seeing that there was no saving it…

Ji Yuan hurriedly recalled the Demon Fire with a thought.

The vast sea of fire was withdrawn, growing smaller and smaller, and by the time it flew back in front of Ji Yuan, it had turned into a tiny, ghostly green spark.

He flipped his right hand, and put away this incomparably powerful Yin Corpse Demon Fire.

First time using it in battle today, and he was extremely satisfied.

Once the Yin Corpse Demon Fire was withdrawn, the long-necked Serpent on the ground had already gone completely silent.

The seawater that remained was not scalding hot from the blaze; on the contrary, it felt even colder.

With a beckoning motion, a water-blue Demon Pill fell into Ji Yuan’s hand.

Compared to a normal Tier Three Demon Pill, its size was still a bit smaller.

“Still water-attribute. Why are ice-attribute Demon Pills so rare? Don’t tell me I really have to kill a Frost Serpent just to upgrade the Fish Pond?”

Ji Yuan looked at the remaining Demon Beast bones, plus the scales that hadn’t burned.

They were probably worth quite a few Spirit Stones.

So he casually put them away into his Storage Bag.

Then he released his Divine Sense again, originally planning to see if he could find that other stone door Yu Yuan mentioned.

But as soon as his Divine Sense spread out, he let out a soft “Hm?”

Because he discovered that on that section of stone wall that had been scorched by the Yin Corpse Demon Fire, a strange mark had actually appeared.

Before he came in, when he was still at the entrance, he’d already used his Divine Sense to scan the entire cave.

He definitely hadn’t seen this mark back then.

So the only explanation was that this mark had appeared only after being scorched by the Yin Corpse Demon Fire.

Ji Yuan took a step and came to the stone wall.

The mark in front of him looked like a long serpent biting its own tail, coiled into a circle.

But looking closer, he could see that the serpent had four claws.

If you said it was a dragon, it didn’t have a dragon’s head, nor any other dragon features. It looked downright strange.

Ji Yuan originally intended to inject a thread of Mana to see what would happen, and even raised his hand.

But in the end he chose to lower it.

No rush.

Finish the main task first, collect the Spirit Liquid, then talk.

He’d come back later to see what this mark was all about.

After that, he made a circuit around the cave. Very soon, he found a tightly shut stone door at the other end of the cave.

The outside of the stone door was covered in countless claw marks, but none of them were deep, only scratching the surface.

’Blocking Divine Sense is one thing, but this stone is actually this hard too?’

Ji Yuan immediately sent out his Divine Sense for another sweep, and found that it wasn’t just this stone door that was made of the Divine Sense-blocking stone.

The entire section of wall in front of him was made of the same material.

Rather than saying they took this stone to make a stone door, it would be better to say they carved a stone door into this stone wall.

Ji Yuan discovered the place where the Seal was to be inlaid to open the stone door, but he wasn’t in a hurry to open it.

Instead, he first smashed a punch into the stone wall beside the door.

“Bang—”

With a dull thud, the stone wall before him didn’t change in the slightest.

Not even the faintest trace of a fist mark was left behind.

“So hard!”

Surprised, Ji Yuan had already summoned the Canglan Sword Embryo.

“Go!”

He pointed his sword forward, the Flying Sword shot out, and amid a spray of sparks, it finally left a pit about the size of a fingertip on the stone wall.

…Damn, just how hard is this stuff?

Does it really take a Nascent Soul Cultivator to work as a miner to extract this ore?

But looking at it this way, this stone door in front of him definitely wasn’t opened up by the Merfolk Race. They must have just picked it up ready-made.
