The excavation work proceeded smoothly, and a cave with a length of more than ten meters and a diameter of three meters was dug out within a short time.

However, at present, no strange place has been found, so we still need to wait for some time to know whether there will be those situations mentioned by Lin Feng.

Lin Feng waited patiently outside.

As time goes by, three days later, a 50 meter long cave was excavated. The speed is not too fast. It is understandable, because this kind of ore vein is often very special and extremely strong. It is quite troublesome to dig such a ore vein. It is not easy to dig such a long cave in a few days.

From Lin Feng's own point of view, he is quite satisfied with this speed.

Yes, of course.

It would be better if it could be faster, but some things don't seem to be forced.

"Still nothing!". Poison Zu said, this guy is more anxious than Lin Feng.

From Lin Feng's own point of view, he thinks there should be no big problem, but it's not true, and Lin Feng can't guarantee it.

Lin Feng said, "wait patiently for a period of time!".

Then it took another three days, and finally some new situations appeared. A very special force filled the air. When the friars digging the ore veins realized this extremely special force, they hurried out to report to Lin Feng.

Hearing the speech, Lin Feng showed his joy. Finally, there was a change. It seems that he is going to find the dark world.

Lin Feng said, "let everyone inside retreat quickly!".

"Yes!" the friar who came to report the news answered, and then the friar quickly went in to convey the order. Before long, all the friars who entered to mine the vein came out.

Lin Feng asked everyone to wait outside. He entered it himself. Duzu and others wanted to go in with Lin Feng, but Lin Feng refused. The reason why he refused duzu and others was not to guard against duzu and others, mainly because if he really encountered terrible danger inside, it would be easier for him to get out alone, but it would be inconvenient if there were many people.

Poisonous ancestors naturally understood Lin Feng's idea of doing so, so they didn't insist. After Lin Feng entered the cave, he did find a weak force. This weak force was coagulated but not dispersed, which was strange.

However, this weak force does not have a growing trend. This situation makes people feel a little confused. It is reasonable to say that since this force has spread out, it should flow out continuously, but there is no such situation. What is the specific matter remains to be discussed.

Lin Feng continued to walk inside. Before long, Lin Feng came to the deepest part of the cave. After coming here, Lin Feng began to carefully check the situation of this place to see if he could enter this special dark world.

But after checking, Lin Feng found that there was no special dark world.

This special force escapes from a deeper place. It's good. In a deeper place, there is no space and no world. This is different from what Lin Feng expected before, which surprised Lin Feng very much.

Lin Feng tried to dig the last distance. As the rocks continued to fall off, more and more special forces escaped.

However, this special force is not very aggressive, that is, it is a relatively mild force.

Lin Feng dug a distance of more than one meter and two meters again, and he saw that an arm appeared in his sight.

This is not a human arm. It is very thick and dark all over. Lin Feng is not particularly clear about what kind of arm it is. Just that kind of extremely special power escaped from this arm.

Seeing this arm, Lin Feng was surprised. He had thought about many situations before, but he didn't think of this situation. What's the origin of a mysterious arm?

Lin Feng plans to take out this arm and study it again. However, when Lin Feng is about to touch this arm, Lin Feng suddenly has a bad feeling in his heart.

He quickly cast the magic spell.

His body became unreal.

When Lin Feng's body became unreal, an extremely terrible force gushed out of the arm.

This extremely terrible force killed Lin Feng.

However, because Lin Feng's illusory spell has been successfully performed and his body is in an illusory state, although the attack released by this arm is very powerful, in fact, it does not cause too much threat and damage to Lin Feng.

After Lin Feng successfully resolved the attack released by the arm, he seized the gap and quickly sealed the arm with the powerful seal magic power of the forbidden God eight seals.

When this arm was sealed by Lin Feng, Lin Feng was able to breathe at last. He put this arm away and left the cave quickly.

Seeing Lin Feng coming out, poison Zu and others came up. Poison Zu asked, "childe, have you ever found anything?".

Lin Feng nodded. There are many people here. It's not suitable to say these things. He said, "let's go back and talk!".

Lin Feng and others quickly left here.

Back to the house.

Lin Feng took out the sealed arm. He said, "this is what I found!".

"One arm!".

Poison Zu and others were very surprised.

"It's not a Terran arm, it doesn't seem to be a demon arm!" Alonso said.

Lin Feng said, "it's hard to say what kind of arm it is, and this arm can release powerful power. The power released from the inside of this arm attacked me just now. Fortunately, I was more alert and avoided the attack of this arm. Otherwise, the attack just now will certainly cause me no small harm!".

"Is this arm so weird?" everyone was surprised.

At this time, Beibei flew out of time and space.

The little guy was sleeping before. Sleeping is training for him.

Now fly out, let Lin Feng some accident, Beibei pointed to this arm.

Then he began to cry.

Hearing Beibei's words, Lin Feng suddenly showed his surprised face.

Poison Zu said in surprise, "it seems that Beibei knows the origin of this arm. What is this little guy talking about?".
