A thick iron chain was 100 meters long, and Ao Ling followed it into a cave.

But there was something in this cave that made Ao Ling stunned, this cave was not wide, and Ao Ling saw that there was not only one such thick iron chain, but five such thick iron chains.

These five iron chains are connected from a tunnel, and these five thick iron chains are tightly locked to a seemingly very ancient coffin suspended in the air, this coffin is also very huge, can accommodate dozens of people as huge.

What Ao Ling saw was not only this huge coffin, but the bottom of the coffin was full of pills, there were probably nearly a thousand pills, and these pills also exuded very strong medicinal power.

"Teacher, am I dazzled?" Ao Ling rubbed his eyes, thinking that everything in front of him was all hallucination.

"Surprised!" Phantom Elder slapped Ao Ling, feeling that he was shocked when he saw these pills, and he was a person without foresight.

"Can you still take these pills?" Ao Ling walked to the side of the huge coffin, squatted down and picked up an elixir and looked at it, blowing lightly, the dust on the pill was immediately cleaned, exactly the same as the pill that had just been refined.

"These are all five-grade pills!" Phantom Elder also picked up a pill curiously, which made his old face suddenly appear in horror.

"There are hundreds of kinds of pills, and the medicinal power is all top-level varieties, and the refining of these pills is probably all from the hands of one person. Ao Ling Li's gaze saw the problem with these pills.

"I can't even do it to be able to refine all of these pills, this person can refine so many top-grade varieties of pills, and the level of the refiner is probably not what I can imagine. There was amazement in the phantom elder's eyes, and he looked closely at all the pills on the ground.

"Don't worry about it for now, put it all away. ”

"Wait!"

When Ao Ling just wanted to put all the pills into the ring, Phantom Elder stopped him with a solemn expression.

"Come and see here!" the phantom old man stared at the coffin.

"Is there anything strange?" Aoling looked at the coffin and didn't notice anything unusual.

"Use your Blood Light Pupil to take a look. Phantom said with a solemn face.

"Blood Light Demon Pupil!"

However, Ao Ling also immediately opened the Eye of the Blood Light Demon Pupil, and when he saw this coffin, his face was immediately full of surprise.

He saw that the huge coffin was made of bronze, and that the coffin was covered with dense rune spell marks.

Not only this huge bronze coffin, but even these five thick iron chains are engraved with dense rune spell marks!

"It's all rune spell marks, what's going on?" Ao Ling didn't know why the bronze coffin was engraved with dense rune spell marks.

The phantom elder also frowned, and he spared the bronze coffin, and there was no place that was not engraved with rune spell marks.

"This is the rune spell seal of the seal!" the phantom old man looked at the bronze coffin with some confusion and a solemn expression in his eyes.

"Could it be that this bronze coffin is sealed with something?" Ao Ling guessed.

"The teacher is also curious to know the reason, but if this is just a seal and the power of the rune spell is engraved with it, I'm afraid the things inside are not so simple. Phantom Lao said in a condensed voice.

"This bronze coffin is at least 10,000 years old, right?Even if it seals something, it's useless, what is there in the world that can withstand the years of time?" Ao Ling felt that this bronze coffin had obviously gone through 10,000 years, and even if it sealed anything, it had already turned into ashes.

"Click!"

Phantom Lao gently stroked the thick iron chain with his hand, and the chain actually made a cracking sound, only to see that the place where Phantom Lao had just touched the chain burst open.

"It's the runes that make the iron chain fragile, and this iron chain is not ordinary iron, and now it cracks when you touch it, and it has been tens of thousands of years. "Phantom Lao is very aware of why the iron chain cracks at the touch of it, and now knows how many traces of age this bronze coffin has.

"Either way, we'd better not touch this bronze coffin. Phantom Elder said seriously.

"Hmm!"

Ao Ling nodded in agreement, and then asked Phantom Elder with a smile, "What about these pills?"

"Take it all. "Phantom Lao used the power of his fighting spirit to suspend all the pills under the bronze giant coffin in the air, and all of them were quickly accepted into the ring by Aolin

"If these pills are put up for auction, it's really, tsk!" Ao Ling completely felt that he had picked up a large amount of wealth now, a wealth that many ordinary people could not get in their lifetime.

However, after taking all these pills into his own ring, Ao Ling also left here immediately, but before leaving, he glanced back at the hanging bronze giant coffin, and he felt that this bronze giant coffin seemed to have something.

"Whew!"

The phantom elder possessed himself and flew directly out of the thousand-meter-deep hole, and Ao Ling immediately began to find a relatively clean place to sit cross-legged and cultivate.

The aura here is compelling, and with the breath of the residual emperor, Ao Ling runs the breath trick technique, and quickly attracts it into his body.

In less than a short time, Ao Ling was already the pinnacle of the six-star smeller, and he was very surprised.

But he was not so anxious to continue to improve his strength, but began to let the Phantom Elder tell him how to refine these thirteen blood bones.

If you want to refine blood and bones, you need to master the secret art of runes, but Ao Ling doesn't know rune spells at all, so the phantom old man has to help him refine them.

The phantom old man pinched the seal with one hand, and quickly recited the rune spell seal on his mouth, and yellow rune spell seals appeared out of thin air and wrapped around Ao Ling's body.

"Whew!"

And the thirteen blood bones were also wrapped around the yellow runes of the phantom elders, and as a result, the blood of those bones seemed to have evaporated.

However, these thirteen blood bones slowly attached to Ao Ling's chest and arms, and began to slowly integrate into Ao Ling's body.

"Ahh

Thirteen wanted to make blood and bones and merge into Ao Ling's body at the same time, he felt a sharp pain in his body, he couldn't bear it at all, and the next shout started.

"Wash the marrow and change the tendons, the eight-star golden light, the Xuanqi rune!"

When the phantom elder saw Ao Ling's painful appearance, he immediately quickly recited the rune spell seal spell method, and one after another mysterious rune spell seals densely surrounded Ao Ling's whole body.

"Son, after holding out for a while, you will be stronger. Phantom Lao stroked his beard and said softly.

But Ao Ling was surrounded by dense runes at this time, and he couldn't hear the voice of the phantom old man at all, he only felt a very sharp pain in his chest and arms.
