In the deep passage, the seven Jindan disciples of the Ten Thousand Demon Sect listened to the words of the Corpse Demon Ancestor and looked at each other, and many of them had a look of horror on their faces.

"Okay, these are just the worst guesses made by this ancestor, maybe those golden corpses and heavenly corpses cultivated by the Corpse (yīn) sect back then were already wiped out by the armies of the demons and demons in the ancient war, and it is impossible for them to survive until now, so you don't need to worry too much. The Corpse Demon Ancestor smiled and said.

Hearing this, the other people's faces gradually improved, but they no longer had the same excitement as before.

The Corpse Demon Ancestor saw all this in his eyes, but his face was silent and continued to fly forward along the underground passage under his feet, and soon disappeared into the depths of the passage with the seven disciples.

And inside the Heavenly Corpse Old Man Cave Mansion, which was thousands of miles away from the underground passage, Duan Chen and the three of them were still cautiously walking along the cave passage.

Strangely, however, the three of them had gone almost miles deep into the cave, but until now, they had not encountered any danger.

In this regard, Duan Chen not only did not feel the slightest joy, but felt a faint uneasiness in his heart.

"Jin Daoyou, didn't you say that there are iron corpses and silver corpses in the cave of the old man of the heavenly corpse, and there may even be golden corpse guards?

The Flame Demon General said with a suspicious expression: "And is this really the cave of the Heavenly Corpse Old Man? How does it look more like a naturally formed labyrinth cave?"

"Hehe, you don't know that the reason why the old man of the Heavenly Corpse built the cave in this cave in the first place was because he took a fancy to the (yīn) environment of this cave, which was of great help to the refining of corpses. ”

Master Jin Yuan explained, "Therefore, in order not to damage the environment of this cave, the Old Man of the Heavenly Corpse did not make many changes to this cave, but only built a few palaces (diàns) in the deepest part of the cave. ”

"As for why there are no iron and silver corpses guarding this cave, maybe it's too big for us to be lucky enough to encounter them, or maybe something happened before we came here. ”

Listening to the meaning of his words, it seemed to mean something, which made Duan Chen and the Flame Demon General think of the iron corpse and silver corpse corpse they had seen all the way in the valley outside the cave before.

Could it be that the original guards in this cave were also killed by the mysterious murderer

Just as Duan Chen was thinking like this in his heart, a terrible scream suddenly came from the deepest part of the cave, and the scream came to an abrupt end.

"What's going on?" the Flame Demon Demon's face changed slightly.

"Just look at it. Master Jin Yuan's face sank, and then he said in a cold voice.

Immediately, without waiting for Duan Chen and the Flame Demon to react, they quickly flew towards the deepest part of the cave in a (shēn) shape.

After Duan Chen and the Flame Blasting Demon General glanced at each other in some surprise, they immediately hurriedly harnessed the light and chased after them.

In this way, after turning seven or eight passages in a row and flying out for several miles, the eyes of the three of them suddenly lit up, and a large open space appeared in front of them, as if it was a cave square.

There were a large number of iron and silver corpses scattered in the square, and if you looked closely, the wounds on these iron and silver corpses that died in the square (shēn) were the same as the wounds of the iron and silver corpses in the valley before, and even more terrifying.

However, this was not something that surprised Duan Chen and the others.

What really surprised them was that among the iron and silver corpses, there sat a humanoid monster wearing rags and shēn (hun) with silver hair.

At this moment, the silver-haired monster was holding a headless silver corpse with both hands, and was looking down at something near the heart of the silver corpse, looking at the freshness of the wound on the silver corpse's head, it was clear that it had not been long dead.

Seeing this, Duan Chen's heart was cold, and he had faintly realized that those iron corpses and silver corpses that died in the valley and cave were probably all done by the silver-haired monster in front of him.

At this time, the Flame Explosion Demon General swept around with a somewhat heavy face, and then the pupils in his eyes shrank secretly, and said with a little surprise: "Lu Daoyou, Jin Daoyou, look at that." ”

Duan Chen and Master Jin Yuan had previously focused their attention on the silver-haired monster (shēn), and when they heard this, they couldn't help but look at it, only to find that at the end of the square, there was an ancient stone gate.

The style of the stone gate is simple, and the patterns engraved on it are also very peculiar, at first glance, it is not the style of the current immortal cultivation world, and there are three fist-sized spirit stones inlaid on the stone door.

I saw that the three spirit stones inlaid on the stone door were shining with crystal light on the surface, covered with spirit patterns, and there was an amazing aura fluctuation faintly contained inside, which looked quite extraordinary.

"Top-grade spirit stones!

At this moment, the Venerable Jin Yuan on the side seemed to recognize the origin of the three spirit stones, and shouted in surprise.

When Duan Chen and the Flame Explosion Demon General heard this, they couldn't help but be shocked in their hearts.

You must know that in the cultivation realm under the end of the Dharma era now, the value of a high-grade spirit stone is much higher than before ancient times, and even if the Yuanying monk wants to get a few high-grade spirit stones, it is not easy.

This was well understood by the Venerable Master Jin Yuan, who was once a monk of the Yuan Infant (shēn).

The reason why the high-grade spirit stone is so scarce, in addition to the environmental impact under the end of the law era, is also related to the crazy mining of the high-grade spirit stone veins in preparation for the great war before the ancient times.

After all, if you want to support a long-lasting battle, or even a life-and-death crisis involving the clan, the amount of spirit stones that need to be consumed is absolutely staggering.

After the end of the Great War of the Three Ancient Clans, in order to cultivate and recuperate and regain their vitality, the demand for high-grade spirit stones was even greater.

Therefore, once a vein above the level of a high-grade spirit stone is found somewhere, the various forces of the Donghua Continent will directly mine it out, or use the magic of the great power to move the entire vein into the mountain gate and seal it.

Therefore, from ancient times to the present, the number of high-grade spirit stones circulating in the market in the entire Donghua Continent has become less and less, and almost all of them are controlled by the major sect forces.

In addition, due to the influence of the depression of the spiritual energy in the end of the law era, there have been no new high-grade spirit stone veins in the entire Donghua Continent for a long time, which makes the value of the high-grade spirit stone higher and higher, and even faintly become priceless.

Of course, a disciple of the Ten Great Immortal Dao Sects like Duan Chen, if he could afford to pay the price, he could still exchange some high-grade spirit stones from the sect.

But for those scattered cultivators who have no background, as well as some small families and sect forces, it is extremely difficult to get a high-grade spirit stone, and there is no way to even find it.

Therefore, when they saw the three high-grade spirit stones inlaid on the stone gate, Duan Chen's three hearts all moved, and they even faintly looked forward to the treasures that might exist behind the stone gate.

However, before exploring the stone gate, the three of them had to work together to kill the silver-haired monster.

After all, this monster didn't look like it would let them probe behind the stone gate.
