Taking a deep breath, Li Dahan is vigorous and vigorous. He tries to condense his vitality and smashes it against the metal semicircle wall!

"Boom

A heavy roar sounded, and the fort was intact!

Li Dahan, however, was shocked by the force of the shock. After the shock, he stepped back a dozen steps, and his arm was numb!

Tang Long was a little surprised: "what a strong fortress!"

"Young master, let's turn around and see if there is a door on this strange thing!" Lin Xi dreamt

"Good!"

Tang Long nodded.

In fact, he also felt that there should be a door for this strange metal fortress.

Together, they began to circle around the metal for half a circle. Finally, they saw a door, but at this time, the door was completely closed and tightly fitted.

If it wasn't for the sign on the door, they wouldn't even see it!

Tang long looked down at the red flame lion and said, "the natural material and treasure you found are in this?"

"Yes, it's right in here." Red flame lion nodded.

Tang long looked at Li Dahan: "break this door open for me!"

"Good!"

Li Dahan agreed. This time, he was much smarter. He no longer used his fist to smash it, but called out the golden Kui Niu!

Gold Kui cattle power is infinite, and has grown to the level of a sacred beast!

If the golden Kui Niu can't open the door, then Tang Long and they can only think of other ways.

"Moo!"

With a roar, the golden Kui Niu retreated for more than 20 meters. His body glittered with gold, and his eyes were shining with dazzling golden light. The terrible golden light burst out from his body!

Eyes such as electricity, staring at the front of the metal door, suddenly, a pair of golden Kui Niu's front legs, on the ground ruthlessly step on!

"Boom

The whole ground is shaking!

The golden Kui ox trampled down the ground, and there were countless sparks!

However, the ground is still intact!

seeing this situation, Tang Long and his colleagues were shocked. They all looked down and looked at the ground covered by thick dust. All of them were shocked again!

The ground is actually made of metal!

"who is this? Who is making such a big pen and using such precious metal to build such a house? There must be many good treasures in this house!" Li Dahan was full of expectation and said: "boss, we are rich now!"

Tang Long's heart, is also very looking forward to!

He also felt that there should be a lot of precious things hidden in this metal fortress.

But in his heart, he was worried again!

If the fortress is full of skeletons and flame men, what can I do?!

Looking at it, the golden Kui Niu dashed against the heavy iron gate. Tang Long quickly yelled: "hurry up, gather your energy and prepare carefully. Maybe there are many monsters in this fortress!"

Hear Tang Long say so, Tang Yang three people, in the heart of a tight, hastily each summoned out, own divine beast!

If it's true as Tang Long said, they'll have to run away!

The golden Kui Niu, with the classics, rushed to the front of the big iron gate. On his head, that pair of glittering golden horns, with dazzling golden vigor, directly and forcefully hit the big iron gate!

"Boom

The roar of terror sounded like thunder!

A flash of gold sparks, from the glittering sharp corner, and the iron gate collided with the explosion, sparks scattered!

The fierce momentum is sweeping in all directions!

Tang Long and they look carefully. The iron gate in front of them is still intact!

Even, not a trace left!

"Hiss!"

Seeing this situation, even Tang Long took a cold breath!

He had never seen such a hard metal!

Although the materials used to make artifact are hard and abnormal, those artifacts have been specially processed and arranged with strange arrays to absorb the energy of heaven and earth, and even contain mysterious spirits to protect them. This will make them extremely hard and can not be damaged.

However, the metal used to build a strong fortress is obviously not a artifact at all!

Moreover, there is no Rune array on this kind of metal. Tang long can be sure of this!

however, how can such metal be so hard that even the gold Kui Niu can hit it, the metal can be intact!

It's amazing!

"It seems that we have to find another way to open the iron door!"

Tang long thought in secret.

In this strange fortress, there are natural materials and treasures discovered by red flame Tianshi. More importantly, Tang Long always felt that if there is something hidden in such a strong fortress, it must be priceless!So, he wanted to open the gate and go inside the fortress!

After hitting the big iron gate, the golden Kui Niu staggered back and stood there, his eyes were confused and his eyes were shining with stars. Obviously, he was stunned by the collision, and he was almost unable to stand steadily.

Tang Long went to the big iron gate and carefully examined it.

The big iron gate is closed very dead. There is a box in the center of the gate. In the box, there are some strange digital buttons and some strange patterns, but they are definitely not array runes!

"There is absolutely no Rune of array on this door. Besides, there is no lock. How can it not be opened?" Tang long can't understand it!

But at this time, suddenly, far away came the thunderous roar!

"Roar!"

"Roar, roar!"

The roar soon became dense, and then from afar, in all directions, a skeleton flame man rushed towards this side, and a strong momentum full of decadent breath swept over towards this side!

"No, it's disturbing the skeleton flame man in this city!"

Tang long looked around, thousands of skeletons of flame people rushed out, immediately in his eyes, a touch of shock!

And at this time, there are more and more skeletons in the distance!

"Go first, get out of here, and we'll come back when the flame skeletons are gone!" Tang Long said, directly jumped on the back of the red flame lion, and Lin Xi dream of them, at this time also together, jumped on the back of their respective god beast!

"Roar, roar!"

The roar of the flame skeletons shook the sky and the earth, followed by blue flames, like meteors flashing with blue light, towards Tang Long and they were bombarded by the sky and earth!

"Come on, fly, fly!"

Tang Long yelled out in a hurry!

All of a sudden, the four people's god beast roared to the sky and flew up in the sky!

it was just flying up less than 20 meters. Below, dense green flame meteors were bombarding the strange metal fortress!

Suddenly, thunder like roar sounded, this strange fortress, bombarded Mars scattered!

However, the fortress is still intact!

around, there are a lot of skeletons and flame men. At this time, they raise the attack height and aim at the flying Tang long. They bombard them fiercely. The dense green flame meteors chase Tang Long and they bombard furiously!

"Come on, fly!"

Tang long forehead, all exude a layer of sweat!

The number of these skeletons flame people is so terrible that it exceeds 10000, and is still increasing. In the abandoned city below, the dense green light flame meteors are all facing them, and they are crazy to attack!
