Lin Feng and the Twelve Dragon Kings, following the Dragon Clan as the Dragon Emperor, were directly taken to Qilong Mountain after returning to the Boundless Domain Dragon Clan.

This is the retreat and cultivation place of the Dragon Emperors of the Dragon Clan, and it is also the place where the ancestors who founded the Dragon Clan and left a sealed bloodline in the Immeasurable Domain.

"Back then, the ancestor who founded our dragon clan sealed a few drops of heart essence blood in his body in this cave. ”

"Every 500,000 years, if no one can get the approval of the heart essence blood sealed here, then the heart essence blood sealed in the cave will explode with a bang, turning into rich and pure majestic energy, and it will merge with Qilong Mountain and even the entire Infinite Domain. In this way, it is ensured that the dragon clan can have enough time to give birth to a truly strong man. ”

"There were four drops of the essence blood in the heart that was sealed at the beginning, and except for the three drops that had melted in nearly two million years, only the last drop remained. ”

"Now, it's time to open the seal again, so the old man will open the seal directly today. The two of you, who can enter it and get the approval of the last drop of the ancestors' heart and blood depends on your creation!"

In front of a cave that towered over the highest peak of Qilong Mountain, the Ninth Dragon Emperor stopped and stood in the air.

After speaking, his hands flicked towards the void.

His whole person is like being completely integrated with the entire Qilong Mountain. Between the ten fingers, the void in front of him appeared out of thin air.

These light patterns contain a special aura of power, and between the criss-crossing, it actually outlines the outline of a star scroll.

"Click!"

The light pattern astrolabe fell on the power light curtain that sealed the cave, like a key inserted into the keyhole, and with a crisp sound of 'click', the power light curtain of the seal disappeared suddenly, and the cave was clearly presented in front of him.

"Boom!"

Almost as the sealing power light curtain disappeared, a violent force swarmed out of the cave.

The impact of the vast power was like a rolling torrent after the rivers and lakes burst their banks, and the moment they raged out, even the previous Dragon Emperors, including the Ninth Dragon Emperor, were all puffed up by their blowing clothes, and their long hair flew sideways.

Even, they need to release a part of their strength in order to continue to maintain their footsteps in the air and not retreat.

However, Lin Feng and the Twelve Dragon Kings did not feel the slightest bit of power raging. On the contrary, this raging power, after wrapping the two of them, carried a kind of sun-like warmth.

"This ...... Is it?"

The ninth Dragon Emperor was the first to notice such a scene.

His eyes fell on Lin Feng and the Twelve Dragon Kings, and he shouted excitedly.

"Nine Dragon Emperor, what's going on?"

"Isn't it, the two of them have already been recognized by the ancestors?"

The other more than ten Dragon Emperors also quickly noticed such a special scene.

In an instant, all of his attention was focused on the Ninth Dragon Emperor. Just from the words of the Ninth Dragon Emperor just now, it was enough for them to make a clear and accurate judgment. In such a situation, the Ninth Dragon Emperor must be very clear about the reason.

Moreover, judging from its excited appearance, there is a chance that among the two, there will definitely be someone who will be able to get the last drop of heart blood left by the ancestor of the dragon clan.

"Not bad!"

The Ninth Dragon Emperor nodded affirmatively.

In the words left by the ancestors, it is very clear that such a scene now will appear after it has been approved by the blood of the heart.

It's just not clear who will finally refine this last drop of heart blood by Lin Feng and the Twelve Dragon Kings, who have all been recognized.

"Great!"

"That's great!"

When the other more than ten Dragon Emperors heard this, they could no longer suppress the excitement and excitement in their hearts, and shouted loudly.

They knew very well what this situation meant, plus Lin Feng and the Twelve Dragon Kings had the same physique as the ancestors, it was really very possible that another ancestor-like existence would be born in the future.

Even if you can't, you can become the real first person besides the ancestors!

"Uncle Twelve, the two of us, are we competitors now?"

Feeling the warmth wrapped in that kind of power, and listening to the excited shouts of more than ten dragon emperors, Lin Feng teased with a smile.

"Haha, it's really rare to have the opportunity to fight with you kid!"

The twelve dragon kings, looking up to the sky and laughing.

For a long time, he has always praised Lin Feng's luck.

Not to mention the Kunxu where Lin Feng was before, even if you look at the entire Immortal Sect, or even the mysterious family that exists beyond the world, I am afraid that there will be no one like Lin Feng who has such luck.

"This time, I'm afraid I won't be able to compete with you. ”

Lin Feng whispered secretly in his heart.

As early as the moment when this force enveloped him, he figured out what was going on.

If you want to get the last drop of heart essence blood, the first prerequisite for refining it is that you must have the body of a dragon. His physique, although he has the same path, is the same as the Twelve Dragon Kings, and is formed by the condensation of the five elements of spiritual energy. But the previous ontology was very different, one was the flesh and blood of the human race, and the other was the natural dragon body of the dragon race.

"Woohoo!"

The moment the whisper fell, the bodies of the two of them, wrapped in this vast and surging power, were like a streamer of light, fleeting, disappearing into the cave.

"Boom!"

In an instant, the power light curtain that sealed the cave reappeared.

"Went in, both of them went in. ”

"Next, it's time to wait, who can finally refine the last drop of heart essence blood left by the ancestors, and when they get out of the customs, we will be able to know. ”

The Ninth Dragon Emperor said with a smile, the excitement and excitement on his face became more and more intense.

"Why don't we just wait here, waiting for them to come out?"

"Anyway, forcibly waking up from the state of dragon sleep, and then wanting to enter it, it takes an extremely long time. In that case, it's better to wait here, and when the final answer is revealed, let's go into retreat and practice with peace of mind. ”

The remaining dozen or so former Dragon Emperors opened their mouths to propose.

"That's a good idea!"

The Ninth Dragon Emperor nodded slightly with a smile.

……

There is the ancestor of the dragon clan, the last drop of the blood of the heart in the sealed cave.

After Lin Feng and the Twelve Dragon Kings entered it, everything in front of them suddenly became clear.

Judging from the entrance of the cave outside, the cave does not seem to be very big, but after entering it, it is a completely different cave.

The entire cave was large and empty, and there was nothing in it except for a drop of essence blood at the top of the most central position, wrapped in a dense and condensed light of power. However, in the cave, it was filled with a rich aura, and its richness was much, even compared to the core of the hinterland of the Wufu Sea.

"Lin boy, this drop of essence blood wrapped in the condensed power light curtain should be the last drop of essence blood left by my dragon clan ancestor!"

The attention of the Twelve Dragon Kings, for the first time, was completely attracted by such a drop of essence blood wrapped in a condensed power light curtain.

"That's it!"

Lin Feng nodded, his eyes slowly narrowing unconsciously.

Even his face became much heavier.
