At the Beishan Base, Manager Qian had gathered five level-6 practitioners and ten level-5 practitioners. When they were about to set off, Manager Qian was horrified to find that Lin Feng's signal had disappeared from the doomsday watch.

The signal of the doomsday watch has always been transmitted by satellite, and the signal can be received even in a deep place underground. If the signal of Lin Feng's doomsday watch disappears, it means that Lin Feng is now in a completely closed place. If there is no lead around, then Only powerful energy can block the signal of the doomsday watch.

"Elder Sima, the leader seems to have had an accident. His signal on the doomsday watch suddenly disappeared. I plan to take some more people to the place where the leader originally planned. Will Elder Sima go with you?"

Manager Qian sent a message to Elder Sima through the Doomsday Watch. Manager Qian has never encountered such a situation. Even if the leader disappeared last time, his Doomsday Watch did not disappear. Right now, Lin Feng didn’t know what happened. Manager Qian has lost his sense of proportion.

"The leader had an accident and I should have gone, but both of us have left, what should we do at the base, or the old man will go to the leader, and you will stay and manage things at the base."

Elder Sima immediately responded to Mr. Qian's message, but how could Mr. Qian let Elder Sima take risks?

Although Elder Sima's cultivation base is higher than that of Manager Qian and he has more experience than him, but at his age, he will not be allowed to go to dangerous places. After hearing Elder Sima's words, Manager Qian immediately objected.

"Elder Sima, the mountains on the north side are too dangerous. Let me go. You stay and manage the base. There are so many practitioners following you. We will definitely bring the leader back."

After Mr. Qian finished speaking, he turned off the communication system, and led a dozen or so practitioners towards the mountains to the north.

Underneath the mountains on the north side, Lin Feng was wearing five layers of fireproof clothing, and he was a level nine practitioner. So he was not injured by the high-explosive grenade, and the level 6 zombies under his feet would not be injured by this small grenade. The purpose of Lin Feng's doing this was to block the upper exit and prevent the level 6 mutated zombies from running out.

After the entrance of the cave collapsed, Lin Feng was buried by a large amount of soil, and the tail of the snake wrapped around his feet was also loosened. In the completely dark environment, Lin Feng felt that kind of energy fluctuation again. This time, the energy fluctuation he felt was the ability of a second-level practitioner. It seemed that the lower the level, the stronger the energy fluctuation.

He took out another electric pick from the supermarket, and after coming out, Lin Feng followed the energy fluctuations and started digging with the electric pick. Because of the explosion just now, the ground under Lin Feng was hard for a while, and soft for a while.

After nearly 20 minutes, Lin Feng finally dug a different piece of land. The land here is red and warm, and the soil is also carrying energy fluctuations.

The soil here is very soft. You can dig with your hands, and after a few casual digs, light appears under the ground.

When the red light entered Lin Feng's sight, a familiar feeling reappeared, and this feeling was exactly the kind of energy in the three-headed blood bat cave.

Opening up the ground below him, Lin Feng fell into a cave with its own red light. The red light in this cave seems to be the source of energy. Lin Feng also found some murals here.

The murals on the walls are colorless. It is completely crudely carved on it, except for the murals, there are also some texts on the other side of the wall.

Lin Feng first looked at the murals. The murals recorded a war, a war between humans and beast races. The reason why it can be concluded that it is a beast race is because the opposite side of humans is all giant werewolves. The murals show The ending is that humans defeated the orcs with the help of advanced weapons, and the orcs were forced to retreat to the cave, but humans did not want to let the orcs go, so humans used weapons to slaughter the orcs, and the remaining orcs could no longer survive on the ground. Survival on the ground, can only live in seclusion underground.

From this point of view, these murals were left by the orcs.

On the wall on the other side, Lin Feng could tell that the characters were normal human characters, so there was some conflict. Since the murals were left by the orcs, why were the characters human?

Lin Feng carefully read the words on the wall. The words also recorded the war between humans and the orcs, but there were other things added in the end.

The last content mentioned in the text explains the origin of this cave. This cave is a relic of underground civilization. It was once a temporary place for peaceful coexistence agreed by humans and beasts. left.

According to written records, there is a secret door in the northeast corner of the cave, through which you can reach the former living place of the orcs.

"It's fate to be here. If I'm destined to want the relics of the orc race, then I'll go and have a look. It's a blessing in disguise. I was trapped here but found this cave. I thought there was no way out, but it reminded me that there is a way out." Secret door, since that’s the case, I’ll go and have a look.”

Being able to have such a cheerful attitude in a difficult environment shows that Lin Feng has indeed grown a lot, not only the growth of strength, but also the growth of mind.

The compass brought out from the supermarket can still be used in the underground cave. Although I know that this world is different from my original world, the north-south direction is still the same, so the compass has played its role here.

Finding the northeast corner, Lin Feng tentatively pushed it. He felt that the wall could move, and there was no sign of collapse at the top. Lin Feng boldly pushed hard, and a door that was one person high and one person wide appeared in front of him. energy is more powerful.

When Lin Feng walked into the cave, there was also red light inside, but the scene in front of him was beyond description. A whole tall city appeared in front of him. Standing in front of the houses in the city, Lin Feng looked like a dwarf.

"It turns out that this is where the orcs lived. It's really tall."

Lin Feng looked at the ruins of the orc race in front of him, and unconsciously started talking to himself.

Lin Feng walked along the spacious street to the center of the city, and as he walked, Lin Feng discovered a strange thing.

The closer it is to the center, the smaller the buildings are. When Lin Feng walked to a place like a square, the surrounding buildings were almost as tall as Lin Feng.

The so-called square is a huge circular platform, and there is a building in the middle that resembles a Chinese pillar. Walking in and observing, this building is full of words, and they are human words.

"Isn't this the city of the orcs? How can there be human writing? It's really strange here."

Looking at the densely packed text, Lin Feng had many doubts in his heart.

Doubts are doubts, what we need to do now is to let go of the doubts and find a way out.

Among the densely packed text, Lin Feng found a different piece of content.

"The magic wolf technique?"

Lin Feng looked at these words and said them unconsciously. (To be continued.)
