All of the crystal cold sky flowers on this crystal cold sky tree have reached the level of seventh-grade immortal medicine.

Tang Long was naturally very happy to have such gains. In this way, after he went back, these high-quality crystal cold sky can be taken by Ye Qingling and the others, and their strength will inevitably be greatly improved.

Of course, outside this Crystal Sky City, there are also many crystal cold sky flowers of average quality. These Tang dragons have all been collected into the Closing Heaven Flag and will be used by those warriors with relatively weak strength in the Tang Mansion in the future.

In the next time, Tang Long continued to break into the Crystal Sky City.

Time flies, and in a blink of an eye, four days have passed. With Tang Long's efforts, he has already broken through the tenth Crystal City.

There are still the last two crystal sky cities left!

After the fierce battles these days, Tang Long's gains were of course very great. Not to mention anything else, he got thirty-six seventh-grade immortal medicine-quality crystal cold sky flowers!

Unfortunately, he has never obtained the crystal cold sky of the eighth-grade immortal medicine. "The last two crystal sky cities are left, and I hope to have a greater harvest!" Tang Long thought to himself, and turned to look at Gongsun Moer and Beidou Tianqing: "Looking at this point, we are about to break into this crystal sky city. Next, I am afraid we will destroy the sky.

It's city!"

Beidou Tianqing nodded. He looked at Tang Long with deep expectations in his eyes: "Young Master Tang, your current strength should be invincible in the Youmei Continent, so you will definitely get what you want when you travel to Destroy the Heavenly City!"

"I hope!" Tang Long smiled faintly.

He had heard of the comprehensive strength of the warriors in the Youmei Continent before, and he also felt that his current strength should not have any rivals in the Youmei Continent.

But he still had one concern about this Seomei Continent at this time, that is, the problem of natural disaster whirlwinds.

"Okay, let's not say much, I'll go to the eleventh Crystal City to see!" Tang Long said.

After such a long fierce battle, Tang Long has already had a good experience in how to deal with the crystal holy demons in Crystal Sky City. Now he is able to deal with those crystal holy demons with powerful combat power.

Moreover, with his continuous fighting, he became more and more proficient in the use of the various laws and the cooperation of his magic weapons, and could better exert the power of the magic weapons.

After making full preparations, Tang Long's body flashed and had already passed the space gate in front of him to the main hall of the eleventh Crystal City.

The situations that appeared in the halls of Crystal City before did not appear at all at this time.

The hall was empty and there was nothing. Tang Long investigated the surroundings and found no danger at all.

The Crystal Holy Demon does not exist at all!

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

Tang Long was curious, but he was still very cautious. He carefully investigated the surrounding situation. He first used the ancient formation of Tianmei Wild Wild Formation, and then summoned all his magic weapons.

Immediately afterwards, he summoned Xuanyuan Tian Formation and others from the Tianfeng Banner.

After making full preparations, he flashed and rushed out of the hall. In a blink of an eye, he had already left the hall and looked around.

There are various palaces of different sizes of silver shining around, but it is obvious that there is no living thing!

"Why are there nothing?!"

Tang Long thought to himself that he never noticed that there was a crystal holy demon here. After thinking about it, he flew up and looked out of the Crystal Sky City.

There is no crystal cold sky outside this Crystal Sky City at all!

There are trees around, and there are big and very dense forests, and the whole place is quiet.

"What will happen in the center of the big square here?" Tang Long thought curiously and flew towards the big square in Crystal Sky City.

There is also a large pool in this big square.

There is also a large and large energy barrier outside the pool, which completely seals and isolates the pool.

Before, Tang Long could see a large and large crystal cold tree that had grown for many years in every pool of Crystal City, but there was no crystal cold tree in this pool.

There is a big, dark black hole in the center of this pool!

The diameter of the black hole is more than ten meters, and the depth is not bottom-out!

"What will happen in this dark black hole?" Tang Long thought to himself. For no reason, a feeling of fear suddenly appeared in his heart deep in his heart!

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

Tang Long had this sense of fear and suddenly became extremely cautious. "In this black hole, there may be some powerful monster. Maybe it is a very powerful crystal holy demon. But at this time, with the isolation of the energy barrier, I have no idea what is in this black hole, even the aura

Can't detect it!"

"I can't take risks. It seems that the safest way is to do it!"

Tang Long thought to himself that although he could unlock the powerful defensive barrier arranged outside the pool, he did not do so.

He used the Tianmei Savage Ancient Formation, and then directly controlled the 108 ghosts in the Tianmei Savage Ancient Formation, and arranged a powerful Pangu Long Ancient Formation outside the pool!

"With my current strength, if you use this ancient Panlong formation, no matter how powerful the things that appear in this black hole are, I believe they will definitely be able to deal with them!"

Thinking in his mind, Tang Long's mind moved and left the God of Destroying Thunder in the Ancient Panlong Formation.

He himself stayed outside the formation.

At this time, the Panlong Ancient Formation had been opened, and above the Panlong Ancient Formation, the Tianzhen tripod had already flew up, and the powerful sealing power enveloped the Tianzhen tripod, covering the entire Panlong Ancient Formation.

"start up!"

After making the most complete preparation, Tang Long moved his mind and directed the ghost to open the Panlong Ancient Formation. Suddenly, a blood-red energy disc array with a diameter of more than 1,000 meters gradually condensed above the Panlong Ancient Formation.

Moreover, on the periphery of this ancient Panlong formation, an extremely powerful blood-red defensive barrier has been condensed!

After the strength of the defensive barrier had reached a very high level, Tang Long was the world-destroying Thunder God controlled the ancient Panlong formation. Suddenly, the world-destroying Thunder God closed his hands in the formation and quickly changed his handprints.

Five minutes passed in a blink of an eye.

At this time, in the ancient Panlong formation, the blood-red energy disc array in the high altitude, the sound of roaring the sky was constantly ringing, and the extremely terrifying roars continued to come out of the blood-red energy disc array!

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

Then there were terrifying bombardment sounds continuously coming from the blood-red energy disc array at high altitude. Clear cracks appeared on the blood-red energy disc array at this time!

And at this moment, under the control of Tang Long's mind, the world-destroying Thunder God in the formation had also unlocked the energy barrier covering the outside of the pool inside the formation!

The energy barrier is untied, and the black hole in the pool will have no energy barrier!

Tang Long still couldn't know what was in the dark black hole outside the ancient Panlong formation.
