All the crystal cold ceiling on this crystal cold sky tree has reached the level of seven grade fairy medicine.

Tang Long is naturally very happy to have such a harvest. In this way, after he goes back, these high-quality crystal cold ceiling can be used by Ye Qingling, and their strength will certainly be greatly improved.

Of course, outside the Crystal City, there are also a lot of ordinary crystal cold ceiling. All these Tang dragons have been collected into the sky sealing flag, which will be used by the weaker warriors in the Tang Dynasty in the future.

The next time, Tang Long is to continue to break into this block of crystal city.

Time is in a hurry. Four days have passed in a twinkling of an eye. With Tang Long's efforts, he has already broken through the tenth crystal heaven city.

There are still two crystal cities left!

In these days of fierce fighting, Tang Long's harvest is also very big, not to mention anything else, but this tenth crystal heaven City, he got thirty-six crystal cold smallpox with seven grade elixir quality!

It's a pity that he never got the crystal cold ceiling of eight grade fairy medicine.

"There are still the last two crystal cities left. I hope we can have greater harvest!" Tang long thought in his mind and turned to look at Gongsun Mo'er and Beidou Tianqing: "with this eye, we are about to finish the crystal city. Next, I'm afraid we will go to destroy the sky city."

Beidou Tianqing nodded. He looked at Tang long, and his eyes were full of deep expectation: "childe Tang, your strength now should be invincible in the enchanting land, so you will certainly get what you wish for when you go to destroy Tiancheng!"

"I hope so." Tang Long smiles lightly.

He had heard about the comprehensive strength of the warriors in the enchanting mainland before, and he also felt that his current strength would not have any rivals in the enchanting mainland.

But for this enchanting continent, he still has a problem to worry about at this time, that is, the problem of natural disasters and cyclones.

"Well, don't say much. I'll go to see the 11th crystal city!" Tang Longdao.

After such a long time of fierce fighting, Tang Long has a good experience on how to deal with the crystal demons in the crystal heaven city. Now he is very handy to deal with those crystal demons with strong fighting power.

And with his constant fighting, he became more and more proficient in the use of the power of various laws he mastered and the cooperation of his various magic weapons, so as to better play the power of magic weapons.

Ready to make full preparations, Tang Long's body flash, has passed through the door of space in front of him, to the hall of the eleventh crystal heaven city.

The situation that appeared in the main hall of those crystal city did not appear at this time.

The hall was empty, and there was nothing. Tang Long explored the surrounding area and found no danger at all.

Crystal demons don't exist at all!

"Strange, why is there no crystal saint in this hall?"

Tang Long was curious in his heart, but he was still very cautious. He carefully explored the surrounding situation. First, he displayed the Tianmei wild ancient array, and then summoned all his magic weapons.

Then he summoned the Xuanyuan heavenly array from the sky sealing flag.

When he was fully prepared, he was in a flash and headed for the outside of the hall. In a flash, he was out of the hall and looked around.

There are all kinds of silver glittering palaces of different sizes around, but it is obvious that there is no living thing!

"Why nothing?"

Tang long thought in his mind that there was no crystal demon here. After thinking about it, he flew up and looked out of the crystal city.

Outside this crystal city, there is no crystal cold ceiling at all!

It's surrounded by trees. It's big, big and dense. It's quiet.

"What's going to happen in the middle of the big square here?" Tang Long curiously thought, toward the crystal city that big square flew past.

There is also a big pool in the square.

Outside the pool, there is also a large energy boundary, which completely seals the pool.

Before, Tang long could see a big, big, crystal cold sky tree that had been growing for many years in every water pool of crystal heaven City, but there was no crystal cold sky tree in this pool.

At the center of the pool is a big, dark black hole!

The diameter of the dark black hole is more than 10 meters, and it is not bottomless!

"What will be in this black black hole?" Tang long thought in his heart, for no reason, a feeling of fear suddenly appeared in his heart!

"It seems that there is a very strong danger in this black hole!"

With this fear, Tang Long became extremely cautious.

"In this black hole, there may be some powerful monster, maybe a very powerful crystal saint. But at this time, with the isolation of energy boundary, I have no idea what is in this black hole, and I can't even detect the breath!""I can't take a risk. It seems that's the safest way to do it!"

Although Tang thought that the water dragon could not solve the defense outside, he did not.

He displayed the Tianmei wild ancient array, and then directly controlled 108 ghosts in the Tianmei wild ancient array, and arranged a powerful Pangu dragon array outside the pool!

"With my current strength, if I use this ancient Panlong array, even if the things in this black hole are more powerful, I believe I can deal with them!"

Thinking in his mind, Tang Long's mind moved and left the destroying Thunder God in the ancient Panlong array.

He himself stayed outside the formation.

At this time, the ancient Panlong array has been opened, and the Zhentian tripod has already flown above the Panlong ancient array, and the powerful seal power has covered the whole Panlong ancient array.

"Start!"

With the best preparation, Tang Long's mind moved and directed the ghosts to open the ancient Panlong array. Suddenly, a blood red energy disc array with a diameter of more than 1000 meters was gradually condensed over the ancient Panlong array.

Moreover, in the periphery of the ancient Panlong array, there is already a circle of extremely powerful blood red defense border!

After the strength of the defense barrier has reached a high degree, Tang Long is controlled by the ancient Panlong array, which means that his hands are closed and his fingerprints change rapidly.

Five minutes passed.

At this time, in the ancient Panlong array and the blood red energy disc array in the sky, the sound of the sky shaking roar has been constantly sounded, and the terrible roar is also constantly coming out of the blood red energy disc array!

"Boom, boom, boom, boom..."

Then the sound of terror bombardment came out from the high-altitude blood red energy disc array. On the blood red energy disc array, there were clear cracks!

At this time, under the control of Tang Long's mind, the God of doom in the array has also untied the energy boundary around the pool in the array!

The energy boundary is untied, and there is no energy barrier for the dark black hole in the pool!

Tang Long is outside the Panlong ancient array, and still can't know what is in the dark black hole.

What's more, there's nothing coming out of the black hole.

Tang Long's mind moved outside the ancient Panlong array. All of a sudden, the doomsday Thor in the ancient Panlong array flashed to the front of the black hole, and then directly condensed the power of the lightning law and bombarded the black hole with the most fierce thunder and lightning!
