Chapter 200

Seeing this situation, Lin Feng couldn't help frowning. The rock in front of him was so hard, which he had never expected before.

After carefully observing the rock in front of him, Lin Feng found that it was indeed somewhat different from the one he dug before.

The stones he dug before were all blue, but the rocks in front of him had some silver in the blue. Touching it with his hands, Lin Feng felt a coolness coming from the stone.

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

In a rage, he increased the energy injection in his hands, and Lin Feng operated the electric pick and pushed it towards the rock in front of him.

"when!"

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

It's so tough!

Seeing the scene in front of him, Lin Feng couldn't help opening his mouth wide.

Although the electric pick is an ordinary tool for demolishing walls, it is specially designed for this kind of work, and its picks are all made of professional materials. Although it is not indestructible, it is also particularly hard.

And the pickaxe shattered directly after hitting the rock in front of him, which meant that the rock was too hard.

Lin Feng touched the rocks on the walls on both sides with his hands, and found that they were different from the ones in front of him, and they were still the same kind of rocks he had dug before.

Could it be that a particularly hard rock in front of him blocked the way? Lin Feng thought to himself.

Back at the entrance of the cave, Lin Feng took the two pickaxes again, and returned to the small hole he dug again.

Replaced the pickaxe. Lin Feng dug towards the wall next to him. A lot of rubble fell from the wall, Lin Feng wanted to bypass this hard rock.

But an hour later, Lin Feng finally found to his annoyance that this was not just a solid rock in front of him. He spared a full ten meters. I found that no matter where I started digging, after advancing to a certain level, I would eventually encounter the same hard rock as before.

Lin Feng found that the hard rock exposed at the ten meters he walked seemed to be connected together. The surface is smooth and hard, without any breaks.

Could it be that this is a separate wall? Such an idea suddenly popped up in Lin Feng's mind.

In his original world, the underground vaults of some banks were designed like this. That kind of vault is built underground, and then surrounded by thick walls made of hard steel and other materials. In this way, even if some robbers want to dig holes from the ground to the vault to steal money, it is impossible. They couldn't break through the hard outer wall of the vault.

The scene in front of him is a bit like the vault in Lin Feng's previous life, except that it is not made of metal, but a real stone.

But thinking of this, Lin Feng wondered more and more what was behind this solid wall. Now Lin Feng has a feeling that the hard stone in front of him is not naturally formed, but man-made.

Because the width of ten meters was dug continuously. Lin Feng could easily see the barrier in front of him that was about ten meters wide and taller than a person.

Lin Feng found that besides being very smooth on the surface of the huge stone in front of him, there were also traces left by man-made tools. There are some small scratches on the top of the wall, which should be left by the machine.

And Lin Feng tried to touch the stone in front of him with the electric pick in his hand, but it didn't leave the slightest trace. That means he didn't make these crossings. But it has already been left behind.

But Lin Feng didn't want to give up just like that. He had been digging here for seven days, and he couldn't give up just because of a hard barrier. If there is really something good in it, it might be snatched up by the people on the mountain. Lin Feng wanted to enter the mountain before they discovered the secret.

Putting down the electric pick in his hand, Lin Feng took out from his waist the dark iron bayonet he took out from the supermarket earlier. This bayonet is said to be made of black iron, so it is also very sharp.

Using 60% of the energy in his body, Lin Feng poured it into the black iron bayonet in his hand. Without hesitation. Lin Feng held the knife and slashed towards the rock in front of him.

"boom!"

Under Lin Feng's powerful energy, the rock in front of him was chopped down into several pieces of rubble.

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

It seems that this weapon is better, Lin Feng thought to himself.

Since the black iron bayonet can cut the rock in front of him, Lin Feng no longer hesitated, and continued to cut at the rock in front of him.

"Bang bang bang..."

As Lin Feng went down with a knife, gravel continued to fall from the rock in front of him.

However, the rock was extremely hard, and after a full hour of chopping, Lin Feng was able to cut off the surface of the rock to a thickness of one meter. It can be seen that the hardness of the rock is so strong. If it was changed before, Lin Feng would be able to travel nearly ten meters in an hour.

Since it has an effect on the rock in front of him, Lin Feng can't give up. Time passed little by little, and Lin Feng kept chopping the rock in front of him with the black iron bayonet.

With every meter he advanced, Lin Feng felt that the energy fluctuations around him increased by one point. With such an effect, Lin Feng continued the work non-stop.

Another seven days passed, and during these seven days, the rats raised their demands on those caught. Within a week, the depth of other people's digging reached almost 100 meters, but Lin Feng encountered the hard rock after digging a thousand meters. It took seven days for Lin Feng to penetrate less than 100 meters.

But despite this, Lin Feng's speed of digging hard rocks is no less than that of ordinary people digging holes. At this speed, if other ordinary people dig for another two months, they will probably be able to touch that kind of hard rock.

But they are ordinary people, and electric picks have no effect on hard rock. It is estimated that by then the forces on the mountain will use their practitioners.

But even then, they may not be able to dig the hard rock like Lin Feng. The black iron bayonet in Lin Feng's hand is something that does not exist in this world. As for whether other weapons have any effect on hard rocks, Lin Feng doesn't know.

On the eighth day, Lin Feng returned to his small cave as usual. He has been digging the cave for half a month. After going a hundred meters deep into the solid rock, Lin Feng felt that the energy fluctuations around him were very active.

This day, Lin Feng used the black iron bayonet to chop the solid rock in front of him as usual, but when he cut down suddenly, Lin Feng stopped the movement of his hand.

Originally, he felt the force from his hands loosen, but what he saw next surprised Lin Feng.

A small hole was cut out by Lin Feng in the solid rock in front of him, and a beam of light shone from the hole. (To be continued.)
