Under Chen Yang's operation, the gold line pattern grew slowly, from nine rows and three rows of copper balls to ten rows and four rows.

As a whole, it looks like three rows and four columns of gold wire connecting nine rows and three columns of copper balls, extending to ten rows and four columns.

Also on the line connection moment, Chen Yang suddenly took back his hand, shouting: "go."

As he made a sound, he snapped the door open.

Then, with a loud bang, the iron door swished and opened backward very quickly, revealing a crack.

He uses seven star sky Gang step, swish then entered the iron gate.

Yan Guinan, Yu Ziwen, and Jiang Wentao were all prepared to enter the iron gate from the top, middle, and bottom positions according to the previous allocation.

Just as they entered the gate, the gate closed with a roar.

The golden line pattern that Chen Yanggang just portrayed, also at this moment, was defeated by the electric awn on the iron door and turned into nothing.

Gradually, the flame and lightning dispersed, and the golden lines on the surface of the iron gate also lost their light. The iron gate was calm again. Except for being a little clean, it seemed that nothing happened here.

……

"It's so dark!"

Chen Yang's first reaction when he entered the gate was that it was too dark inside.

It is reasonable to say that he has reached the extraordinary sixfold, and his eyesight has been able to reach night vision, which will not be affected by the light.

But into the hall, his line of sight, but only less than 10 meters.

Farther away, it was a gray fog, and nothing could be seen clearly.

"It looks like the fog is blocking the view."

Chen Yang said in secret.

"Are you all in?"

At this time, Yan Guinan's voice sounded.

"Here we are."

"I'm here."

The crowd responded one after another, and then followed the voice, gathered to the side of Yan Guinan.

Seeing that all four of them entered the hall, Yan Guinan was relieved. Then he looked at Chen Yang and said, "younger martial brother Chen, thanks to you just now. I didn't expect that your array attainments were so high."

Chen Yang said: "I have not been able to crack the golden thunder fire array. I'm a little embarrassed that elder martial brother Yan praised me so much."

"I also practice array, but compared with you, I'm far behind."

Yan Guinan praises Chen Yang.

He went on: "in all kinds of secret places, ancient tombs and dangerous places, there are often artificial or natural arrays, and this ancient tomb is no exception. Now with you, as long as we don't encounter too abnormal array, we will not be hindered by the array. "

Hearing this, Jiang Wentao said nothing and his face became more and more ugly.

It's only a short distance. Chen Yang is in the limelight no matter facing the red clawed bat king or the golden light thunder fire array.

But he, Jiang Wentao, seems to have done nothing.

In his view, he lost to Chen Yang before, is his own carelessness, was unexpectedly defeated by Chen Yang.

But now he found that the distance between himself and Chen Yang was growing.

This makes Jiang Wentao feel bad.

"Come on, don't waste your time here."

Jiang Wentao said impatiently and walked forward.

Yan Guinan didn't want to reprimand Jiang Wentao too much, so he didn't want to cause Jiang Wentao's rebound, which was not conducive to the harmony of the team, so he nodded: "let's go."

Four people continue to move forward, just action, but also to the door behind, to judge the direction of progress.

But after walking dozens of meters, I could see nothing but a fog.

In this way, Chen Yang four, simply can not judge the direction.

Yan Guinan stopped and said, "stop first. Don't hurry. We have to find a way to judge the direction."

Jiang Wentao looked at Chen Yang and said with a smile, "younger martial brother Chen, don't you have any instruments? You try now, can you judge the direction

"Judging the direction, I can really do it."

Chen Yang ponders a smile, just some mists, don't try to stop him.

He took a rope and a dagger from the ring.

These things, like the ultrasonic transmitter, were installed in the ring when he left the earth.

Now, it just comes in handy.

Seeing that he took out the rope and dagger, Yan Guinan was puzzled: "younger martial brother Chen, what are you going to do?"

"It's just a simple way to confirm the direction."

Chen Yang picks up the rope, and the Qi moves around. It condenses at the end of the rope. When the end of the rope suddenly attaches a force.

Then, according to the direction he just walked, he waved hard and threw the rope backward.

The rope passed through the fog and disappeared.

Dang.

The sound of the iron door sounded. It was obvious that the rope hit the iron door.Chen Yang cut the rope, then inserted the dagger into the ground and tied the end of the rope to the handle of the dagger.

Then he did the same, throwing two more ropes to the left and right.

In this way, he has identified three directions.

Then, he tied the rope in his hand to the handle of the knife, and said to Yan Guinan: "let's go. Now I can judge which side is the way forward."

Wen Yan, Yan Guinan three people, is still a face at a loss of expression.

Yu Ziwen asked: "your method really determines the way forward. But once we walk out more than ten meters and the dagger is out of sight, we can't see the other three ropes. How can we determine the direction? "

Chen Yang pulled the rope in the handle, pointed to the handle of the dagger, and said, "it's very simple. I gently pull the rope. According to the reaction force from the other three ropes, I can judge the direction."

After listening to this explanation, Yu Ziwen and her three friends suddenly understood the principle.

Reaction force, although very subtle, but for the extraordinary six heavy Chen Yang, but can easily feel.

"Younger martial brother Chen, although your method seems simple, it is quite clever."

Yan Guinan couldn't help but praise it.

Next to Jiang Wentao, his face broke down and he didn't say a word.

According to the direction determined by Chen Yang, the four continued to move forward.

But what Chen Yang didn't expect was that the rope in his hand was more than 1000 meters long, but until the rope was put to the end, they were still in the fog and didn't go out.

If they go further, there is no rope to judge the direction, they will only spin in the fog.

"Oh, no, what's to be done?"

Looking at the end of the rope, Yan Guinan had a headache.

"Ah Wu..."

Just then, suddenly a voice rang out in the hall.

The sound was very loud, deafening and profound, reverberating throughout the hall.

Hearing the distance of sound transmission and reflection, Chen Yang changed his face and said, "this hall is at least tens of thousands of meters wide."

All the people frowned, because when they looked outside, although the hall was large, it was only a few hundred meters wide at most.

It's amazing enough that we have just walked more than 1000 meters and haven't walked out of the main hall.

Now I find that the hall is tens of thousands of meters wide, which is incredible.

"By the way, what was the sound just now?"

Yu Ziwen asked suddenly.
