Lin Feng saw that the people coming and going from the entrance of the cave were ordinary people, most of them were young adults in their twenties and thirties.

These people want to catch so many people to dig holes, is it just for the energy fluctuations in the cave? Lin Feng said secretly in his heart.

Lin Feng felt that the energy fluctuation in the cave was very weak, and even he, a level 7 cultivator, was just able to sense it. If it is said that the hole is dug because of this energy fluctuation, then it means that there are also high-level cultivators on this mountain. Thinking of this, Lin Feng was secretly on guard.

When I came to the entrance of the cave, I found some tools stacked on one side of the hole. Lin Feng had never seen it before, but looking at these tools, it should be like something like an electric pickaxe.

Picking up one of the "electric pickaxes", Lin Feng walked into the cave.

The space inside the cave was not small, and in the empty cave there was a table behind which sat a man in his fifties.

"New here, I'll tell you about it here."

The person behind the table saw Lin Feng coming in, looked at him, and spoke.

Hearing the man's words, Lin Feng walked over. Just as he was about to inquire about how the cave was dug here.

"Here you have a hole per person, go in one direction, and hit at least ten meters a day. Otherwise, there will be no food to eat. ”

Before Lin Feng could ask, after the other party said a word, he ignored Lin Feng.

Looking inside, sure enough, there were thirty or forty small holes in the cave, and from time to time someone pushed a cart, full of stones, came out of the small hole, and then pushed it out of the hole.

It turned out that one person was in charge of a piece, and seeing this, Lin Feng understood the procedure for digging a hole.

Feeling the faint energy fluctuations in the cave, Lin Feng found that the energy wave cave in the northwest direction seemed to be a little stronger. So Lin Feng didn't speak, and walked over directly with an electric pickaxe.

After studying the electric pickaxe in his hand, Lin Feng discovered how to use it. This is something similar to Lin Feng's wall-digging tool in his previous life, but it is wireless power storage. It took almost a day to charge a single charge, which was much more advanced than that of his previous life.

After simply mastering the method of use, Lin Feng came to the place where he had felt the energy fluctuation a little stronger before. I dug into the rock in front of me.

At first, Lin Feng didn't grasp the use of the electric pickaxe, and was splashed by the shattered stones. But after getting familiar with it for a while, Lin Feng mastered the use of this tool.

This tool was much more efficient than Lin Feng's previous life, less than an hour. Lin Feng dug a small hole more than a meter deep.

And after digging a meter deeper, Lin Feng felt that the energy was slightly stronger. But it was just a trace of it, if it weren't for Lin Feng being in the cave, he wouldn't have felt it at all.

Next, Lin Feng completely focused on the work of digging a hole. With this trace of energy fluctuations. Let Lin Feng feel that there is definitely something in this mountain. Otherwise, there would be no such energy fluctuations.

And now Lin Feng guessed that the reason why this place was robbing people to come and dig a hole was related to this energy fluctuation. But digging a hole is a dangerous thing, and people here take this factor into account and go outside to find someone to come and dig a hole. When the secrets of the mountain are discovered, it is the time of death of these people. With such strict layers of guards outside, it will definitely not be so easy for ordinary people here to escape.

But what secrets are in this mountain, Lin Feng doesn't know, and can only find the answer as he keeps going.

Truckloads of gravel were hauled out. The small hole that Lin Feng had dug gradually deepened.

After digging three or four meters deep, Lin Feng blessed the energy into the electric pickaxe in his hand. With the blessing of energy, Lin Feng's burrowing speed suddenly got a great boost. However, Lin Feng still carefully controlled the energy blessed on the electric pickaxe to avoid the discovery of the level 3 cultivator known as the Sixth Master outside.

As for the gravel generated by digging the hole, Lin Feng received them to a corner of the supermarket. Externally, it still maintains the speed of transporting a truckload of gravel for about an hour. In this way, it will not attract the attention of others.

As Lin Feng continued to advance, he felt that the energy fluctuations were getting stronger and stronger. Lin Feng, on the other hand, is getting more and more excited, exploring unknown secrets, which can always arouse people's sense of anticipation.

Lin Feng didn't know how long he had been digging, and suddenly heard a bell. It should be time for dinner. Lin Feng reluctantly lifted the electric pickaxe in his hand and walked towards the outside of the cave. If you don't go out at this time, it should arouse suspicion outside the cave.

Sure enough, the other people who were digging the hole after hearing the bell. They all walked out of their small caves, and gathered more than thirty people outside the caves.

Lin Feng looked around and found that they were all young adults in their twenties and thirties. And their spirits are not very good, obviously they have dug holes for a day, and they are very tired.

Dinner was settled at the mouth of the cave, and one person was given a small piece of bread. There is also a so-called soup that seems to be no different from clear water. Although this kind of food will not starve people to death, it is impossible to eat enough.

Since there is no end time watch, Lin Feng estimates that it is already ** o'clock in the evening. After a day of digging, Lin Feng's small hole had been dug nearly forty meters deep. However, in order to cover up his small hole, ten meters away from the entrance of the cave, Lin Feng had already blocked the entrance of the cave with a big stone. In this way, when others came to see, they could only find that the small hole that Lin Feng had dug was only ten meters deep.

After eating, everyone was taken out of the cave by the rat from before and walked towards a simple wooden house in the back.

Entering the materials, Lin Feng found that this was a room composed of several shops. There was nothing but a few long wide planks inside. A thin layer of straw mats was laid on top of the wooden planks, apparently where everyone slept.

For such an environment, Lin Feng didn't care. It's just that the smell here is really bad. After a day's work, the smell of sweat permeated the wooden house, which was disgusting.

However, the curiosity about the energy fluctuations in the cave still made Lin Feng stay here, but fortunately, after a day of hard work, everyone didn't have the strength to grab a place, so they just found a place to lie down.

And Lin Feng found a place near the door, because it was cold at night, everyone didn't want to be here, but it didn't matter to Lin Feng.

After a while, there was a burst of snoring in the wooden house, and everyone was tired from the day, and soon fell asleep. And Lin Feng tossed and turned, still thinking about the energy fluctuations in the cave.

At this time, Lin Feng heard the sound of talking outside, so he stood up and walked outside. (To be continued.) )
