Lin Feng and the twelve Dragon Kings, who followed the dragon family as Dragon Kings, returned to the immeasurable dragon family and were directly taken to Qilong mountain.

This is the place where the Dragon emperors closed their doors and practiced. It is also the place where the ancestors of the dragon family left sealed blood in the boundless domain.

"In those years, the ancestors who created our dragon family sealed several drops of heart blood essence in this cave."

"Every 500000 years, if no one can get the recognition of the heart blood essence sealed here, the heart blood essence sealed in the cave will explode into rich and pure majestic energy and integrate with Qilong mountain and even the whole immeasurable domain, so as to ensure that the dragon family can have enough time to give birth to the real strong."

"There are four drops of blood essence sealed at the beginning. Except for the three drops that have melted in nearly two million years, there is only the last drop left."

"Now, it's time to open the seal again. I'll just open the seal directly today. It depends on your luck who can enter it and get the recognition of the last drop of blood essence of your ancestors!"

Standing in front of a cave at the highest peak of Qilong mountain, the Kowloon Emperor stopped and stood in the air.

Then he turned his hands to the void and flicked his fingers.

His whole person is like a complete integration with the whole Qilong mountain. Between the ten fingers, the emptiness in front of me emerged out of thin air.

These light patterns contain a special breath of power. Crisscross, they actually outline the outline of a star chart.

"Click!"

The light pattern astrolabe falls on the power light curtain that seals the cave. It is like a key inserted into the key hole. With a clear sound of "click", the power light curtain of the seal suddenly disappears, and the cave clearly appears in front of you.

"Boom!"

Almost when the light curtain of seal power disappeared, a violent force swarmed out of the cave.

The impact of the vast force is like the rolling torrent after the breakup of rivers and lakes. At the moment of raging, even the successive dragon emperors, including the ninth Dragon Emperor, were puffed up by their clothes and long hair.

Even, they need to release some of their strength to continue to stand in the air without retreating.

However, Lin Feng and the twelve Dragon Kings did not feel the slightest force raging. On the contrary, this raging force wrapped them up with a warmth like bathing in the sun.

"Is this...?"

The ninth Dragon Emperor first noticed such a scene.

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

"Kowloon Emperor, what's going on?"

"Isn't it that they have been recognized by their ancestors?"

More than ten other dragon emperors soon noticed such a special scene.

In an instant, all attention was focused on the Kowloon Emperor. Just from the words of the ninth emperor, it is enough for them to make a clear and accurate judgment. In such a situation, the Kowloon Emperor must be very clear about the reasons.

Moreover, if you look at it from its excited appearance, nine times out of ten, one of the two will definitely get the last drop of heart essence left by the ancestors of the dragon family.

"Good!"

The ninth emperor nodded definitely.

In the words left by the ancestors, it is clearly recorded that such a picture now will appear only after it is recognized by the blood essence of the heart.

It's just not clear who will finally refine the last drop of heart essence of Lin Feng and the twelve dragon kings who are all recognized.

"Great!"

"That's great!"

More than a dozen other dragon emperors could no longer restrain their excitement and excitement and shouted loudly.

They know what this situation means. In addition, Lin Feng and the twelve Dragon Kings have the same physique as their ancestors. It is really possible to give birth to another ancestor in the future.

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

"Twelve dragon uncle, are we two competitors now?"

Feeling the warmth wrapped by that power, listening to the excited cries of more than a dozen dragon emperors, Lin Feng joked with a smile.

"Ha ha, it's really rare to have a chance to fight with you, boy!"

Twelve Dragon Kings, look up and laugh.

All along, he has been full of praise for Lin Feng's luck.

Not to mention the kunxu where Lin Feng was before, even if you look at the whole Xianmen, or even the detached mysterious family, I'm afraid no one will have such luck as Lin Feng.

"This time, I'm afraid I can't compete with you."

Lin Feng whispered in his heart.

As early as this force wrapped it, he found out everything.

If you want to get the last drop of heart blood essence, the primary premise of refining it is to have the body of the dragon family. His physique, like the twelve Dragon Kings, is formed by the condensation of the five elements aura. But the previous noumenon is very different. One is the flesh and blood body of the human race, and the other is the natural dragon body of the dragon race.

"Whew, whew!"

At the moment when the whisper fell, their bodies were wrapped in this vast and surging force, like a streamer, flashed and disappeared, disappeared into the cave and disappeared.

"Boom!"

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

"Go in, they both go in."

"Next, it's waiting. Who can finally refine the last drop of heart essence left by their ancestors? After they leave the customs, they can know."

The Kowloon Emperor said with a smile. The excitement and excitement on his face became more and more intense.

"Why don't we just wait here and wait for them to pass?"

"Anyway, it will take a long time to forcibly wake up from the state of dragon sleep and enter it again. In that case, we might as well wait here and wait until the final answer is announced, so we can go to retreat and practice at ease."

The other ten successive dragon emperors proposed.

"That's a good idea!"

The ninth emperor smiled and nodded.

……

The last drop of blood essence of the Dragon ancestors is sealed in the cave.

After Lin Feng and the twelve Dragon Kings entered it, everything in front of them suddenly opened up.

From the outside hole, the cave seems not big, but after entering it, it is completely another, completely different cave sky.

The whole cave is very large and empty. There is nothing else in it except a drop of blood essence at the top of the most central position, which is wrapped by a strong and solid power light. However, the cave is full of rich aura, which is much richer even compared with the core of the hinterland of wuwuhai.

"Lin boy, this drop of blood essence wrapped by the light curtain of condensed strength should be the last drop of heart blood essence left by our dragon ancestors!"

The attention of the twelve Dragon Kings was completely attracted by such a drop of blood essence wrapped in the light curtain of solidifying power at the first time.

"That's it!"

Lin Feng nodded and his eyes narrowed slowly unconsciously.

Even his face became much heavier.
