The beast carrying Tang Long and they quickly flew up a hundred meters, gradually, to the top of the metal fortress parallel!

At this height, the Tang dragons and their beasts can resist the attack of the green light flame group by completing all-round actions!

Their situation at this time is relatively safe.

Tang long does not stay here.

"Come on, let's get out of here first!"

Tang Long commanded the red flame lion, together with Tang Yang and them, resisted the attack of the dense green flame, while flying towards the distance.

Soon, they flew thousands of miles by warp!

Looking around, the crowd was stunned.

Those skeletons of flame, even all together, towards the huge metal fortress, launched an attack!

"Boom, boom, boom -"

the roar was so loud that the metal fortress was completely swallowed up by the blue flame!

The most powerful blue flame, filled the whole sky, within a few kilometers, are the wind howling, blue light flashing hot energy, in the sky and earth continue to wreak havoc!

"I hope those skeletons flame people don't smash the fortress, or the treasures hidden there will be destroyed!"

Tang long thought a little worried.

However, he didn't care much about it. He commanded the red flame lion and flew far away.

After flying forty or fifty kilometers, four people came down from the air to rest. Thinking of the strange fortress just now, they were still curious!

Li Dahan looked at Tang Long: "young master, do you think there are many artifacts in that fortress?"

Tang Long listened to this guy's words, suddenly speechless!

Is artifact so easy to make?!

Such a large fortress, covering the ground, occupies a large circular area on the ground. The diameter of this area is even more than 500 meters, and the height of that fortress is more than 50 meters!

If the fortress is full of artifact, how much can be put in it!

"I don't know who can make such a hard metal into such a strange thing!" Lin Xi has a wonderful dream.

Tang Long is also very curious.

He is curious, who is so rich, so hard metal, to such unscrupulous waste!

These metals, if used to make artifact, can make many, many!

"If situ gang or Ouyang Qian were here, they would be greedy. Take the whole fortress away!" Tang Long secretly thought, his heart, but also have such an idea, want to take this fortress, the whole take away!

His sky flag, I don't know how much space there is, can put this fortress into the whole!

However, the fortress seems to connect with the ground. It seems that the ground is covered with thick metal. How big is this thing?!

If you want to take this fortress away, at least you need to get it off the ground!

However, is this possible?!

Don't say this thing is so big, just this weight, who can move it a bit?!

"Let's have a rest first. After two hours, we'll go back and have a look. I hope those skeletons and flame men will retreat." Tang Long said and sat down with his knees crossed.

Lin Xi dreams of them, also sat down beside them.

Tang long, however, contacted Ye Qingling with huixinmen, and asked in his heart, "dear girl, what is the situation of the five domain King City now? Are they in any trouble? "

"They did have trouble." The little girl said: "however, their trouble is not big, and it will be solved soon."

"That's good." Tang Long was a little relieved.

Ye Qingling asked, "brother long, when will you come back?"

"It's going to be a while." Tang Long stopped and said, "dear girl, you can go shopping with Qingyao in the five regions King City. The city is very prosperous, and now, it should not be too dangerous."

"I've been shopping for days." Ye Qingling said in a coquettish way: "brother long, you come back to accompany us, OK?"

Tang Long was a little helpless.

Now, obviously, he couldn't go back. He had to say, "when I'm finished, I'll go back to accompany you."

"We'll go back to the door." Ye Qingling said: "we have been out for a long time. In a few days, we must go back to have a look. Sister Qingyao said that there is something else in zongmen."

Tang Long said: "it doesn't matter. When I go back, I'll go to zongmen to find you."

"All right." The little girl agreed and chatted with Tang Long again for a while, which cut off the contact with Tang long.

Next, Tang Long contacted Xue linyue.

This little leopard, alone in the Imperial Palace, is forced to practice by Gaoyang Ziyan these days. He goes to the closed door, saying that he wants to lay a solid foundation, and then he wants to take part in a competition in the imperial palace!Tang Long didn't care about the competition. He chatted with the leopard for a while, but he contacted Beigong Xianer.

Time was in a hurry, and soon two hours passed.

Tang Long looks at the time, is and Lin Xi dream of them, riding their respective god beast, again fly high in the sky, toward the abandoned city before, fast flying away!

At this time, the sky gradually darkened.

Tang Long and they are flying very high. While flying, they are still observing the movement below.

The whole abandoned city, quiet!

Before those skeletons flame people, all don't know where to hide. Now, even a skeleton flame man can't be found here, and Tang Long is relieved.

Don't tell them to keep quiet

"Good!"

Tang Yang Lin Ximeng and Li Dahan agreed in a low voice.

Tang Long summoned the pig and golden monkey out of the sky, paying attention to the surrounding activities. Long Ying and long Xuan, as well as the Golden Phoenix, all came out of the heavenly spirit garden.

The red flame lion and the snow wolf king still rest in the heavenly spirit garden.

Once again, the four arrived in front of the tightly closed, metal gate.

This metal fortress is very strong. If you want to solve the secret of the metal fortress, Tang long, the only way for them now is to open the door!

Four people at the door, study for a long time, can not see, so, the door is dead closed, can not open!

"This door should have a mechanism." Lin Xi's dream is thinking about Tao.

Tang Long nodded. He was in favor of Lin Ximeng's idea. He also felt that the door should be controlled by a mechanism. However, after searching for a long time, he did not find any place around here. There was an organ.

Li Dahan is a little impatient.

Looking at Tang long, they continue to study, he ran to the side, relying on the golden Kui Niu to sleep, for a while he fell asleep.

Tang Long is still studying it carefully.

On the iron door, the only thing that might be the mechanism is the row of numbers on it. Those numbers are the keys. But Tang long, after pressing the buttons, did not know how many times, and it was of no use at all!
