Seeing this situation, Lin Feng could not help but frown. The rock in front of him was so hard that he had not thought of it before.

Careful observation of the rock in front of him, Lin Feng found that it is indeed different from the previous digging.

The stones he had dug before were all blue, but the silver in front of the eyes was silvery. Touched by hand, Lin Feng felt a cool meaning from the stone.

At this time, Lin Feng realized that the surrounding energy fluctuations were almost doubled. Although it is still weak, he can really detect it as a 7th-level practitioner.

In a rage, he increased the injection of energy in his hand, and Lin Feng operated the eDonkey to top the rock in front of him.

"when!"

When the electric **** hit the front rock, it not only failed to shake a piece of gravel, but shattered the **** directly.

It’s so hard!

Seeing the scene in front of him, Lin Feng could not help but open his mouth.

Although the eDonkey is an ordinary wall-removing tool, it is specially designed for this kind of work, and its **** is made of professional materials. Although it is not invincible, it is also particularly hard.

When the **** hit the rock in front of it, it broke down directly, which shows that the rock is too hard.

Lin Feng touched the rocks on both sides of the wall and found that it was different from the one in front of him.

Could it be said that a particularly hard rock in front of you blocked the way? Lin Feng’s heart is dark.

Back at the hole, Lin Feng took another two hoes and returned to the small hole he had dug.

Changed a hoe, Lin Feng digging to the side of the wall. A lot of gravel fell from the wall, and Lin Feng wanted to get around this hard rock.

But an hour passed, Lin Feng finally found annoyed, it seems that this is not just a hard rock. He spared ten meters. It is found that no matter where you start to dig, you will eventually encounter the hard rock of the past when you advance to a certain extent.

Lin Feng found that the hard rock that he had exposed at the ten meters seemed to be connected. The surface is smooth and hard with no faults.

Could it be said that this is a separate wall? Lin Feng’s mind suddenly came up with such an idea.

In his original world, some banks' underground vaults were designed this way. The vault is built underground and then made of thick steel walls and hard materials. In this way, even if some robbers want to dig holes from the ground to the treasury to steal money, it is impossible. They can't get through the hard treasury wall.

The sight in front of you is a bit like the kind of gold bank of Lin Feng’s past life, but it is not made of metal, but a real stone.

Thinking of this, Lin Feng is more and more want to know what is behind this hard wall. Now Lin Feng has a feeling that the hard stone in front of him is not naturally formed, but artificially made.

Because of the continuous digging of the width of ten meters, Lin Feng can easily see the barrier that is about ten meters wide and one person high.

Lin Feng found that on the surface of the huge stone in front of it. In addition to being very smooth, there are also traces of some human tools. There are some small scribes on the top of the wall, which should be left by the machine.

Lin Feng experimented with the electric shackles in his hand and touched the stone in front of him, leaving no trace of it. That means that these scribes are not caused by him, but have already been left.

However, Lin Feng did not want to give up, he has been dug here for seven days, can not give up because of a hard barrier. If there is really something good in it, it may be seized by the people on the mountain. Lin Feng wants to know before they discover this secret. First enter the mountain.

Put down the electric cymbal in his hand, Lin Feng took out the black iron bayonet from the supermarket before taking it out from the waist. This bayonet is said to have been made of black iron. It is also very sharp.

Carved up 60% of the body's energy, Lin Feng injected it into the black iron bayonet on his hand. Without hesitation, Lin Feng cut the knife toward the rock in front of him.

"boom!"

Under the powerful energy of Lin Feng, the rock in front of it was cut down by a few pieces of gravel.

Looking at the black iron bayonet on his hand, Lin Feng found no damage on the blade.

It seems that this weapon is still good, Lin Feng’s heart is secret.

Since the black iron bayonet can cut the rock in front of it. Then Lin Feng no longer hesitates and continues to cut toward the rock in front of him.

"Hey..."

As Lin Feng went down with a knife, there were constantly gravel falling from the rock in front of him.

However, the rock was so hard that it was cut for an hour, and Lin Feng cut the rock of the money a meter thick. This shows the hardness of the rock. If you change it, Lin Feng can walk nearly ten meters in an hour.

Since it has an effect on the rock in front of it, Lin Feng can't give up. Time passed a little, Lin Feng has been using the black iron bayonet to cut the rock in front of it.

With each advance of one meter, Lin Feng felt that the energy fluctuations around him increased by one point. With this effect, Lin Feng did not stop doing this work.

Seven days have passed, and in these seven days, the mice have increased their demands on those who have caught them. In the week, the depth of burrowing by others was almost 100 meters, and Lin Feng encountered the hard rock after digging a kilometer. For the whole seven days, Lin Feng was less than 100 meters deep.

But despite this, Lin Feng's speed of digging hard rock is no worse than the speed of ordinary people burrowing. At this speed, if other ordinary people dig for another two months, it is estimated that they can also encounter the hard rock.

But they are all ordinary people, and eDonkey has no effect on hard rock. It is estimated that by then the forces on the mountain should use their practitioners.

But even then, they may not be able to dig hard rock like Lin Feng. The black iron bayonet in Lin Feng’s hand is something that is not in the world. As for other weapons that have no effect on hard rock, Lin Feng is not known.

On the eighth day, Lin Feng returned to his own small hole as usual. He has been working on burrowing for half a month. After a hundred meters deep into the hard rock, Lin Feng felt that the surrounding energy fluctuations were very active.

On this day, Lin Feng used the black iron bayonet in his hand to cut the hard rock in front of him, but suddenly he went down and Lin Feng stopped his movement.

Originally, I felt that the strength of the feedback was loose, but Lin Feng was shocked by the sight that I saw next.

The hard rock in front of him was cut out by Lin Feng, and a light was shining from the hole. (To be continued.) Mobile users please visit http://m.piaotian.net
