Qin Feng, who had stood firm, looked around.

The valley isn't huge, but it's much bigger than it looks like from a hilltop.

On visual inspection, this valley is full of thousands of square meters.

The valley is in the shape of a long gorge.

Outside, there is a cliff with bushes on both sides.

Qin Feng shifted his gaze inside.

Here he has been.

That's how the old man taught him back then.

And the entrance to the underground dragon vein is right here.

There are many weeds and shrubs in the valley.

But there is something abnormal, there are no trees.

This is the dragon's lair, and it is also the entrance to the underground dragon vein.

Under normal circumstances, the energy of the dragon veins nourishes all things, and this place should be full of vitality.

But in fact it is not.

If you look closely, none of the shrubs and weeds in the valley are more than a meter tall.

Even in some places, the mountains and rocks are bare, which looks very desolate.

This is because of this hidden dragon.

This dragon vein has been artificially destroyed.

Originally, there were three fractures.

Two have been restored by the old man for more than ten years.

This last one remains.

The hidden dragon has a grudge, and the resentment is reborn.

And here, as the only break, can also be said to be the only place where grievances are declared.

Naturally, this is the case here.

It's good that it's not dead.

This is also due to the old man's restoration in the past ten years, which has reduced the resentment of the dragon vein a lot.

In fact, Qin Feng knew that with the old man's cultivation, if he repaired it for another five or six years, this last dragon vein break would almost be repaired.

It's a pity......

Qin Feng put away his sigh.

Take a step and walk into the valley.

The entrance to the underground dragon vein is here.

Qin Feng walked step by step.

At the bottom of the valley, the shrubs were peeled away, and a low stone cave appeared.

There are obvious signs of repair around this cave.

When the old man was here, he simply disguised himself.

The bushes just hid the hole.

Qin Feng squatted down and went directly into it.

A bright light helmet was pulled out of the white backpack.

This is prepared in advance.

A few meters after entering the hole, the cave suddenly opened up.

At this time, Qin Feng was already able to walk upright.

The cave is small and big.

After walking a distance of only ten meters, it is already very spacious.

The roof of the cave is already several meters high and three or four meters wide.

It's like a funnel, and the hole is the funnel.

The further you go inside, the more space you have.

The bare, exposed rocks protrude out of the cave, which is a natural formation.

The cool breeze blew, and people couldn't help but shiver.

The temperature here is seven or eight degrees different from the outside.

And as Qin Feng deepened, the temperature became lower and lower.

But fortunately, Qin Feng has the cultivation of the Qi Observation Realm.

This difference in temperature had no effect on him at all.

Under the strong light overhead, everything in the cave is clearly visible.

Qin Feng's pace was fast.

Although he had only been to the cave once, he knew that there was no danger here.

The entrance to the underground dragon vein, and it is the only break of this hidden dragon, and the resentment of its dragon vein has already determined all this.

There can't be any snakes, insects, rats and ants here.

As for anything dirty or something, it's even more impossible.

After all, this is the dragon's lair of the dragon vein.

Although it is already a hidden dragon and has grievances, the dragon vein is a dragon vein after all.

The energy of the dragon vein is also the nemesis of all stolen goods.

So there's generally no such thing as dirt here.

If there really is, it is not something that Qin Feng's current Qi Observation Realm cultivation can deal with.

Qin Feng walked quickly.

The terrain of the cave began to slope slightly.

The passage of the cave has expanded to a certain extent, and it does not change.

The bare, exposed rocks raise the suspicion that the entire mountain is made of rock.

Not really.

If someone digs up this mountain, they will find out.

Only this passage is built in the rock.

The rest of the place should be gravel or gravel, dirt or dirt.

Qin Feng walked in the cave for half an hour before stopping.

Half an hour, calculated according to the footsteps of a normal person, is at least five or six miles.

Qin Feng also made a simple estimate, according to the inclination of the cave, it should be eight or nine hundred meters deep underground at this moment.

The cave passage is not straight, and there are curved paths.

At this moment, the temperature in the cave is only seven or eight degrees.

Qin Feng was wearing a white short-sleeved shirt and carrying a white backpack.

He wears a bright light hat on his head.

What appeared in front of him was a stone chamber four meters high and four meters long and wide.

The rock of the walls of the stone chamber has become smooth.

There are obvious traces of artificiality.

Qin Feng knew that this was the old man's masterpiece.

Directly opposite Qin Feng, on the walls of the stone room, were two stone doors.

The stone gate is three meters high, and the two stone doors are two meters wide.

The stone door is carved with reliefs.

On the left is an irregular pattern, like a rune on a talisman.

These runes look very weird.

A casual glance will give a sense of what you want to say.

But if you look closely, you don't see anything.

On the stone gate on the right is dense text.

"The qi of heaven and earth has yin and yang, and incarnates all things. The qi of the mountains and rivers also has yin and yang, and Zhong Yu Lingxiu is so good at learning, although the number of techniques is also called geography ......"

Qin Feng looked at these words, which were carved by the old man before his death.

The text on it is also the content of the ancient book "Dragon Water Classic".

Qin Feng watched carefully.

The runes on the left have filled the stone door, but the words on the right are not.

And what Qin Feng has to do is to continue to carve words.

That's right, this stone gate was the first step in the old man's restoration of the dragon vein.

The rune on the left is a dragon pattern talisman, carved by infused mental power, which can be regarded as a special magic weapon.

It has the effect of linking and storing the energy of the dragon veins.

The text of the Dragon Water Sutra on the right has the same effect.

All of them need to be carved with mental infusion.

Of course, Qin Feng didn't come to carve right now.

Because this was only the first step that the old man had laid out back then.

Qin Feng retracted his gaze.

A few steps forward, he pressed his hands on the stone door, his left hand pressed a special dragon talisman, and his right hand pressed on a special text.

The mental power in the body begins to work, and it is infused into it.

Hold this for about four or five minutes.

In the past few minutes, the mental power in Qin Feng's body has been fully consumed by one-fifth.

As Qin Feng withdrew his hands.

A rumbling sound rang out in the stone chamber.

Two stone doors slowly opened.

Qin Feng's attention also began to focus.

The old man has been in this Qinjia Village for more than ten years.

Most of the time is spent on this dragon vein.

This dragon's lair was ordered by the old man for three years.

The cave is naturally a natural occurrence.

But this stone door and stone room were all made by the old man with time.

The passage behind the stone gate was also opened by the old man.

According to the original situation, the stone cave reached the end of the stone chamber.

The passages behind the stone gate were all dug by the old man.
