Under three punches, the black dragon collapsed.

But its energy body, but instantly condensed into a weak point, like a firefly, taking advantage of the forest city caught off guard, in the blink of an eye, it rushed to the center of the forest city's eyebrows and flashed in.

This scene let Lin Cheng unexpected, heart crazy at the same time, he immediately urged the mind to explore himself, but it is still a slow step.

In the end, he could only watch the faint black light like a firefly and dart into the mysterious black iron block in his elixir field Disappeared!

The accident happened too fast and caught by surprise. After the reaction, the whole heart of Lincheng fell to the valley.

The unknown black iron block in his elixir field has always been mysterious. Although it is in the elixir field of Lincheng, Lincheng has never understood its origin, nor can it be touched.

Now there is a thousand feet black dragon, and the black fireflies after the collapse of its body make everything more complicated.

With worry, his power of mind circled around the mysterious black iron in the Dantian, trying to explore, but in the end, there was no result.

Under helpless, Lin City can only temporarily throw this matter aside, looking back to find a way to solve it.

As for the present, the urgent task is to explore the cave of Emperor Yu first, and find out the method left by the supreme Emperor Yu in ancient times, which can thoroughly solve the evil spirits in foreign countries

This sealed space is dark, but under the divine sense exploration, everything is fine.

The forest city impels the mind to extend and go. It sweeps around and has a result soon.

The size of the whole seal space is not too vast, but it is not narrow. The area is about 100 li. As a cave, even the cave of the most powerful, is enough.

There is not much in this hundred Li space. The void is dark, just like nothingness. But in this dark void, there are three platforms like altars suspended.

The size of the three platforms is only Lishu. The materials of the platforms are very common, just some lapis lazuli. It seems that they were dug and moved here from the outside.

On the platform, there are some futons, stone tables, stone benches and tables. They are very simple, but they show the meaning of vicissitudes and simplicity. Obviously, they are objects before ancient times.

"Hiss! It was... "

Lin Cheng's sight sweeps through the three platforms and soon settles on the platform in front of the right. There is no Futon on this platform. It should not be the place where the supreme Emperor Yu of ancient times meditated.

Even there are no desk tables, stone tables and benches here. It seems that they are just used to place some sundries.

At this time, there are only some big black pieces on the platform

These black iron pieces vary in size. The small ones are just like the belly, while the big ones are just like human heads. There are quite a lot of them, with nearly a hundred.

Lin Cheng's sight swept through his eyes. When he saw these black iron pieces, his eyelids jumped wildly, and he breathed out his breath. It was because the breath of nearly 100 pieces of black iron on the platform was the same as the black iron in his body exactly alike!

"What's going on here? What on earth are these black iron blocks? How could he even be in the cave of Emperor Yu There are so many? "

Staring at nearly a hundred mysterious black iron blocks of different sizes on this platform, Lin Cheng's brain is in a mess and buzzing

Murmuring light words, he vaguely guessed why the black hair of the black dragon energy body disintegrated at just now, why would it rush into his brow, reach the Dantian, and get into the black iron block in his elixir field.

If there is no accident, the black dragon of the energy body must have something to do with nearly a hundred mysterious black iron blocks on this platform. After the black dragon energy body disintegrates, it turns into a black hair like a firefly.

The reason why he would jump into the center of Lin Cheng's eyebrows, reach the Dantian, and get into the mysterious black iron block in his elixir field is that the black iron block and nearly 100 black iron blocks on the Lixu platform in the front of the right are originally integrated.

In other words, they are all pieces left by something after it breaks

When these thoughts flashed in his mind, Lin Cheng had already shaken his shoulder and pressed his body shape on the platform of Li Xu in the front right.

As soon as Fu Yu fell, his divine consciousness swept through the black iron again, and soon found a jade bamboo slip under one of the larger black iron blocks.

At this moment, Lin Cheng's eyelids jumped, and his eyes lit up in an instant.

Jade slips are used to record information or transmit information. This is the secret cave of the supreme Emperor Yu in ancient times. Now a jade slip has been found. The significance of this is obvious.

"Whew..."

The faint sound of breaking through the sky sounded. As Lin Cheng raised his hand, the jade slip, which was pressed under a black iron block the size of a human head, flew up automatically in an instant and fell on the palm of Lincheng's hand and was directly pasted on his forehead.

In the next moment, a large number of ancient messages poured into Lin Cheng's mind from the jade slips, which made his eyes bright and excitedIn a few seconds, the message left in the jade slips had been fully understood by him. When Lin Cheng put down the jade slips pasted on his forehead, Lin Cheng had no doubt about the origin of the small pile in front of him, including the origin of the mysterious black iron block in his Dantian

In ancient times, Emperor Yu, the most powerful emperor, once refined nine tripods, which is well known to the outside world.

But in fact, in addition to refining the nine tripods, Emperor Yu himself had a magic weapon of his own life, which was the tenth tripod. These black iron pieces were the fragments of the tenth tripod.

Compared with the nine cauldrons known to the outside world, the tenth tripod is more powerful. This can be seen from the fact that Emperor Yu used the tenth tripod as his own magic weapon.

The reason why the tenth tripod is more powerful is that Emperor Yu once killed a half step black dragon in the supreme realm in ancient times and sealed the dragon soul in the tenth tripod, which became the spirit of the tenth tripod!

As for the reason why the tenth tripod was broken, it was not mentioned in the jade slips left by Emperor Yu.

He just said that after the tenth tripod was broken, most of the fragments, namely these mysterious black iron pieces, were collected by him and brought back to this secret cave.

Only the most important piece, can not be found everywhere, unfortunately left out

The fragment of the tenth tripod, which was left outside, was obviously the one in the Dantian field of Lincheng. Now, as he entered the cave of Emperor Yu, the fragments of the tenth tripod finally gathered.

It is for this reason that the forest city entered this secret cave. As the energy form of the tripod spirit, the Qianzhang black dragon became so excited after sensing the breath of black iron in his body's elixir field. He rose to the sky and roared at him at the first time

Its purpose is to recapture the most important piece of black iron in Lincheng Dantian.

In the end, when this goal failed, the Dingling black dragon chose to retreat and seek the second place. Under the collapse of the body shape, it took the initiative to form a black hair like a firefly. It rushed into the heart of the forest city's eyebrows, got into the black iron block in its elixir field, and then dormant
