"Is that a strange mark?"

Lin Yu's face changed slightly, and he stared at the pile of white bones, where there was a dark black strange mark the size of a fist.

For a moment, he looked around, for fear that he was ignoring other good things!

I saw that in the entire bronze hall that was so clean that only dust remained, except for the pile of white bones, only this black and blackened strange mark remained.

It seems that the man cleaned up everything else before he died, but this mysterious black monster mark remains.

At this moment, Lin Yu became more and more sure in his heart, this black strange mark was a mysterious treasure.

"Huh!"

Lin Yu was surprised.

As he reached in with his hand, a cold chill instantly lingered on his skin.

"This is really a baby!" Lin Yu said with a smile on his face.

However, just as he was about to reach out and pick it up, he stopped.

After being bitten by a snake for ten years, he was afraid of the well rope, and with the thrilling experience when he first entered the bronze hall, he was more cautious at this moment, for fear that if he didn't pay attention, he would ...... It's over with the little life.

At this time, I saw Lin Yu take the broken sword in his hand and slash it down, and the sword body touched the black seal, but nothing happened.

In the bronze hall, it is still so quiet.

"Whew!"

Lin Yu sighed lightly and said in his heart: "It seems that I am still too careful!"

"Click!"

However, at this moment, I saw the broken sword in Lin Yu's hand, broken inch by inch, and fell on the jade slab in the bronze hall.

"it!"

For a while, Lin Yu's voice was full of emotion, and his heart was panicked.

"This.... This is also too Nima against the sky, it's just that this touch is gone!" Lin Yu couldn't help but swallow a touch of saliva and exclaimed.

"It's good that I didn't reach for it, what the hell is this?!" Lin Yu looked dazed and looked confused.

"Host, this black monster mark is very likely to be cast from Xuantie Mother Gold!" At this time, the voice of the system instantly echoed in Lin Yu's mind.

Lin Yu's face changed slightly when he heard this, and he became more and more puzzled in his heart, and said, "What is this Xuantie Mother Gold?"

"It is a kind of pure training material that surpasses ordinary iron ore and refined iron ore. The system responded.

"True Nyima is extravagant!" Lin Yu sighed and replied as if he understood or not.

Although he didn't know what this Xuantie Mother Gold was, he knew from the system's narration that this thing was very rare and valuable.

As the so-called 100 refining into steel, an ordinary piece of iron needs to be tempered thousands of times to become refined iron, and this thing is still on top of refined iron.

"As the saying goes, scarcity is expensive!"

Thinking of this, the corners of Lin Yu's mouth rose slightly, revealing a smile that was even brighter than a chrysanthemum.

"It's really worth the trip, damn it's developed this time!" Lin Yu was overjoyed, and couldn't help but reach out and pick up the strange mark that was so black that it glowed.

Suddenly, a touch of cold sweat instantly fell from Lin Yu's cheeks.

His mind sounded like a bell in his head, and he stared at the black strange mark in his hand with trepidation.

"Nima ......" Suddenly, Lin Yu spat out the fragrance and scolded.

He didn't expect that he would pick up this black monster mark like this.

"No..... It's okay!"

Lin Yu's eyes looked around, smiling, and his voice trembled.

"Boom!"

Suddenly, a violent tremor struck me, as if the entire mountain had collapsed in a trembling.

"Bang!"

It was another lifetime of loud reverberation, and at this time, I saw that the two bronze doors closed instantly.

"Don't, don't!"

Lin Yu's face was moved, and he exclaimed.

At this moment, I saw him take three steps and two steps, holding the black strange mark in his hand, and rushed towards the closed bronze door.

"Bang!"

Lin Yu's face was as pale as dirt, and he suddenly slammed his fist on the closed bronze door, but there was no fluctuation in the slightest!

"Ahh

Lin Yu exclaimed, his voice instantly echoed in the Bronze Hall, but no one responded.

He looked at the black monster mark in his hand, and his heart was full of mixed feelings and anxiety.

He knew that if he was locked up in this bronze hall for a long time, he was afraid that he would also be like that old brother, turning into a pile of white bones.

"Whew!"

As soon as he thought of it, Lin Yu's heart hung by his voice.

He was still young, and he didn't want to bury the bronze hall like this.

"It's all to blame for this black seal!" Lin Yu's face became more and more ugly, and he sighed.

System: "........."

In a hurry, I saw Lin Yu pick up the black monster seal in his hand and slam it into the two bronze doors.

"Bang bang bang!"

Suddenly, a loud bang instantly echoed.

"Host, this black seal should be a magic weapon!" At this time, the sound of the system instantly echoed in Lin Yu's mind.

"Magic weapon?"

Lin Yu frowned, looking confused.

"In layman's terms, it means that the auxiliary tools used by the practitioners, such as flying swords, spears, dust, and so on, are all Dharma weapons. ”

"The difference between a magic weapon and a weapon is that a magic weapon has a spirit, while a weapon is a cold weapon. The system responded.

Hearing this, Lin Yu thought thoughtfully, and said, "How should this magic weapon be used?"

"Dharma weapons are carefully tempered by cultivators, and if others want to use them, I'm afraid it's not easy, let alone you ......... so much," the system said again.

Suddenly, Lin Yu's face darkened. Obviously, he understood what he meant.

Obviously, the system was obviously weak in his cultivation and couldn't use this black monster mark.

"If it is an ownerless thing, the host only needs to refine the black seal, but by injecting the aura into this black seal, it can reach a consensus with the black seal!" The voice of the system continued to echo in Lin Yu's mind.

"However, I'm afraid it's a little difficult with the host's current cultivation!" paused, and the system continued.

Lin Yu: ".........."

At this time, I saw several wisps of spiritual energy surging in Lin Yu's body, and that surging spiritual energy instantly surrounded the black seal.

But it didn't work!

Lin Yu didn't feel any implication or consensus at all, but instead the aura in his body was consumed a lot.

"Whew!"

Lin Yu sighed and stared at the black strange mark in his hand, revealing a hint of decadence.

"It seems that he is going to bury the bronze hall for a long time, and he will accompany that old brother from now on. ”

"The host doesn't need to be discouraged, as long as he cultivates hard, it is possible to refine this black seal, and then use the black seal to break open the bronze door. The voice of the system echoed in Lin Yu's mind again.

Lin Yu's expression was in a trance, his face was dejected, and he said: "This broken place where birds don't, I'm afraid I haven't refined this strange mark yet, so I'll burp first!"

As he spoke, he saw Lin Yu reach out and smash the strange seal towards the bronze door.

"Bang!"

At this moment, a sound echoed instantly, and the entire bronze hall swayed and swayed, like a landslide and the ground cracked.

"Gollum!"

At this moment, Lin Yu gasped for breath, staring at the black strange mark that smashed on the ground, and exclaimed in his heart: "This power ...... It's fucking brutal!"

"If this is used to knock bricks on the black seal, I'm afraid it will ...... One knock on the other!"

Lin Yu pondered in his heart.
