Ye Fan immediately noticed that the place in front of him was strange.

These remnants of fire don't look like they were left over from a long time ago.

Because of the rest of the village, the firepower left by the explosion has long since disappeared.

Only this one piece is still there.

And if you observe the day, it should be within half a year.

Ye Fan took out Yan Yanzhu, since he had ready-made firepower, it was a good thing to absorb it.

If the Nether Fire could make Yan Yanzhu cast a burning flame for thousands of miles, the power would be absolutely unimaginable.

At the same time, the tunnel under the abandoned house also made Ye Fan very curious.

Was it left over from the family's study of Nether Fire?

Combined with the reminder given to him by the old man at that time, Ye Fan felt that something might be different.

If there is an explosion here behind it, and it is deliberately covered up, it can only mean that the research is still continuing.

Under the tunnel, it is the nest of the descendants of Na'an Rushan.

As soon as Ye Fan raised his palm, the entrance to the tunnel in front of him immediately opened.

He had carefully noticed, and there were no prohibitions left.

Presumably to hide people's eyes.

If the ban is left, it will be noticed by those who are interested.

Ye Fan walked all the way down the stairs of the tunnel, and the electric lights around him also came into contact with the induction and lit up.

The tunnel spirals downward, and Ye Fan cautiously descends.

It cannot be ruled out that in order to prevent the exposure of this place, the descendants of An Rushan finally placed a ban inside.

Ji Yuntong, who was at the peak of the power of the Nether Fire, could be seriously injured.

I don't know if there's any stock left below, everything is unknown.

If you don't pay attention to it, you may have to take your own life.

Ye Fan felt a little surprised now, he never thought that he would have to be afraid of exploring a basement as a seventh-rank martial artist.

It can also be seen from the side that this Nether Fire is definitely not ordinary.

Such a special flame, if it is used by the people of the Purple Evil Alliance, plus the teleportation technology that the Purple Alliance now has priority mastering.

A great catastrophe can be unleashed at any time.

The most important thing is that this Netherfire is not even sure if he can get rid of it without Yan Yan Zhu.

It can be seen that the power is huge.

Ye Fan slowly released his spiritual power, and extended towards the bottom of the stairs little by little.

The further down I got, the brighter the lights seem to become.

When the stairs reached the end, a small secret room of almost thirty square meters appeared in front of Ye Fan.

The secret room is brightly lit and has some wooden tables and workbenches.

It's just that it's almost empty, and there's nothing.

A step too late?

Ye Fan was not surprised, maybe after the explosion of the Jingyun Auction House branch this time, the other party handled the follow-up carefully.

But after thinking about it carefully, Ye Fan shook his head again.

Something is wrong, if it is dealt with, the tunnel should be buried, there is no need to leave it at all.

This chamber may not be as simple as it seems.

Especially on the edges of those brick-stacked walls, Ye Fan found that his spiritual power in the middle of the seventh rank could not penetrate.

How is this possible?!

With such a narrow range, it stands to reason that his spiritual power completely penetrates the rock formations and observes farther.

Not to mention covering the entire village, it is no problem to completely cover the entire mountain range.

Ye Fan had already noticed the unusualness here, and upon closer inspection, he found that behind this brick, there seemed to be some kind of special metal.

Of course, these metals can isolate psychic power detection to a certain extent.

Not only that, but there is a special prohibition on these metals, and the entire secret room is connected around it.

Ye Fan frowned, he realized that he had missed a point.

That is, from beginning to end, he didn't feel that there was such a place to go

Thing explosion research.

The study of Nether Fire is risky, and accidents can happen at any time, which is how the village did not exist back then.

What's more, the old people in the town had also witnessed the explosion here.

It's just such a place, if it really explodes, it is estimated that there will be no people!

These metals may not be as simple as isolating spiritual power.

At the same time, Ye Fan realized that this might just be a place to rest, not a real place to study.

The only way to do it now is to break through the metal wall behind the bricks.

It's just that Ye Fan is also very aware of the risks, maybe this is a bait trap, once it is touched, it will be doomed.

Ye Fan had no doubt that the other party might bury a bunch of netherworld fires here and have an earth-shattering explosion!

Ye Fan touched his chin, and finally decided to try.

We've all come here, and we can't go back without finding anything.

He wanted to see how hard the metal could be!

Ye Fan took a deep breath, and the Yuan Force in his body was frantically compressed.

Under the accumulation of the Yuan Shrinkage Technique, the power of the four dragons in Ye Fan's body roared out.

Shenwu Dragon Fist!

Ye Fan punched directly at the position he felt was the most suspicious.

Because there is no shelter, no table, no furnishings.

It seems to have been set aside on purpose.

In addition, there are details on the ground, and in this area, the dust on the ground is obviously different from the surrounding area, and it will be lighter.

Of course, Ye Fan was not stupid, he knew very well that once it really exploded, he would not hesitate to enter the Tian Yuan side.

"Bang!"

This punch shook the space, and the space was distorted by the fist wind.

Such a terrifying blow slammed into the brick wall in front of him.

The power of domineering penetrates.

Ye Fan can be said to have mobilized a large amount of his qi and blood power in the late stage of the seventh grade.

The mighty power poured out like a torrent that opened the floodgates.

In the midst of the decay, the bricks in front of him turned into powder in a second.

The metal wall behind was broken through a big hole by Ye Fan's huge force.

Ye Fan had observed that there were no unnecessary prohibitions on the metal walls here.

How to say that he also has top-level formation knowledge, so he can naturally judge the clues here.

There was indeed movement behind the hole, and if you looked closely, you would find that the metal wall where the hole was located was a secret door.

There is also another passage behind the secret door.

I hadn't gone far when I saw a fork in the road.

There are two passages at the fork in the road, one of which is all scorched earth, which contains a rich residual fire of the Nether Fire.

Ye Fan thought that if he absorbed all the Netherfire in the passage in front of him, he would be able to replenish at least half of the Yan Yan Beads that were originally empty.

Ye Fan took out the Yan Yan Bead and released his spiritual power to explore the end of the passage while absorbing it.

In the end, it was discovered that the passage actually led to the surface, and it seemed that the passage itself was an outlet for venting firepower.

After Ye Fan absorbed all the remaining firepower, a gray-blue strange flame surged inside the red Yanyan Bead.

If it's all full, I don't know if the Yan Yanzhu will change color.

Ye Fan wasn't exploring the passage that was really full of scorched earth.

Instead, turn around and head to another passage at the fork in the road.

The residual fire here is more intense, but the passage is not long.

At the end of the passage, there is another fork in the road.
