Zhang Yang walked at the back with a direction instrument, and in front of him were Kong Sen, Xu You, and Kuiba.

These three were responsible for excavating in front, while Zhou Sheng and Cao Mao, the two of them were responsible for sending the excavated mud and stones to the back. Zhang Yang was in charge of looking at the direction gauge. This direction gauge is an ancient thing, it seems that only Zhang Yang can use it alone, and when other people get it in their hands, it seems that it will lose its function, and the pointer is pointing randomly.

"There is no ...... in the direction," Zhou Sheng asked after digging about 10 meters. The direction of his mind is reversed, and it is between 10 and 20 meters.

Zhang Yang looked at the pointer, the pointer was still pointing to the front, and said, "I haven't ...... yet."

Nothing else said, after all, digging is a technical job, and many explorers have never found the right way in their lives.

After digging another 10 meters, Zhou Sheng asked, "Is the direction right......?"

Zhang Yang still shook his head, saying that it was not right. When he said this, he hesitated, because he also felt that the wrong direction was dug between these 20 meters, but he had already dug 20 meters, and the pointer was still pointing ahead, which made him wonder if his direction gauge was also wrong.

The others were a little panicked, because if there was a problem with the direction gauge, then several of them would die here.

Without a direction finder, there is no room to start with.

Their space is only 6 cubic meters, and if they dig in the middle of the inner lake, then they will only be drowned.

"How is that possible?"

Zhou Sheng took out his direction meter again, looked at the pointer, and suddenly dizzy, because his direction meter actually pointed to his feet. Although his direction gauge is not an ancient thing, it is also the best direction gauge in the empire, but at this moment, the direction pointer is pointing downward. Zhou Sheng remembered that the 20-meter distance he had just dug was a vertical straight line, and there was no turn at all. But at this moment, the pointer is not pointing behind, but pointing at his feet, which can only mean that his direction gauge has lost its effect, and there is a force that interferes with his direction gauge.

"My point to the left......"

"My point is backward......"

"My ...... of not moving"

Everyone else also looked at their direction gauges and suddenly collapsed, because at this moment their direction gauges were useless and began to point around.

"Let's go!" Zhou Sheng didn't like to say this, because when he said this, it proved that the expedition was going to be disbanded. At the moment, they are in the mud and rocks, with only 6 cubic meters of space, and if they want to survive, they need to find their own way. There is food and grass, so there is no need to worry about food and oxygen.

"My direction meter points to the left, I go from this side, and I can definitely find a way out......" Kong Sen, a 32-year-old man with his own intuition, was the first to separate from everyone, divided 1 cubic meter of space, and began to make holes in the mud. The others did not blame Kong Sen, because if Kong Sen was not the first to come out, then they would be the first.

Soon, each of the six people took 1 cubic meter of space and headed in the direction where their pointers were pointing. At the beginning, Zhang Yang and Kuiba were in the same direction, because their direction gauges were pointing forward, but after digging for about 20 meters, Kuiba's direction gauge pointed upward, so he broke up with Zhang Yang.

"I'm the only one left." Zhang Yang muttered and dug forward.

The most trusted thing for every explorer is their own direction instrument, even if the direction meter points to a dead end, they have no regrets, after all, without a direction instrument, they will lose hope of survival. In the dark and boundless underground, there are no friends, no light, only their own voice, and if there is no little guidance at this time, anyone will collapse, so the direction meter is the only thing they can rely on.

Zhang Yang has been digging like this for an unknown number of days, and there is no night and day in his underground civilization, but there is a time device.

"It's been 20 days."

After looking at the time machine, Zhang Yang found that 20 days had passed since departure. In the past 20 days, Zhang Yang didn't know how many meters he had dug up, and he didn't know where he had dug up, but Zhang Yang knew that he was getting closer and closer to the time of death, because the red plum grass in his bottle began to bear fruit.

Red plum grass has a 30-day fruiting period in its life, and after these 30 days, it will soon wither.

Zhang Yang couldn't imagine starving to death.

The vast majority of missing explorers end up starving to death.

Dig it!

Zhang Yang's only hope now is that he still has 10 days to live, and if he can't find a new space or a way back within 10 days, they will have to die. Of course, if he can find an inner lake, he will have a chance to live, but digging into the inner lake is also a sign of death, because if the water of the inner lake fills his space by 1 cubic meter, he will be drowned.

After digging for another 5 days, the red plum grass began to bear only 2 fruits, and the light emitted was much dimmer. Zhang Yang knew that the lifespan of red plum grass was approaching.

Dig...... Keep digging......

Another 3 days passed, and Zhang Yang stopped because he had encountered Neihu. The surrounding mud is damp.

The inner lake is the underground water, but for the people of the underground civilization, the inner lake is a demon, because he will occupy the living space of human beings.

At this moment, Zhang Yang's living space is only 1 cubic meter.

Drip...... Drip......

A drop of water began to drip from above him, Zhang Yang hurriedly dug back, but because the mud and stone here are very damp and not solid, a little bang in a place, there will be a lot of mud and stones stepping down, so Zhang Yang dug it, and a large number of mud and stones fell above, and in a moment, there was a thick column of water gushing down. The impact of the water column is very strong, and it quickly becomes thicker.

Finished......

Zhang Yang's space was quickly filled.

When Zhang Yang was conscious, it was in a large hall. The main hall is full of metal pillars.

"Here it is...... Ancient Ruins...... "Zhang Yang knew that he was in an ancient ruin, because there was no such hall in the civilization he was in. The most magnificent hall of the Empire, he had seen, was a stone castle, and this hall turned out to be all metal.

"Energy ......"

A voice suddenly reached Zhang Yang's ears.

"Who?" This voice frightened Zhang Yang. Because the voice seemed to be close at hand, but Zhang Yang was sure that there was no one within his 20-meter range.

"Energy ......," the voice sounded again. But this time, Zhang Yang knew where the voice came from. He looked at the direction meter in his hand, and his heart was full of doubts, and the direction of the heart said that it could speak. Although he thought of the extraordinary power of ancient civilizations, he did not expect that a simple direction instrument could speak.

"Energy Docking...... The docking was successful...... Start your search...... Search: 1%...... 5%…… 18%…… 30%…… 60%…… 89%…… 100%…… Search done...... Discover the Commander...... Objectives (3, 16, 72). A flurry of sounds came from the direction pad.

Zhang Yang was a little panicked at the moment because he flew up.

Zhang Yang's flight was passive, because in his panic, he had already reached a 20-meter-high metal pillar, on which there was a very special metal platform on which a human skull was placed.

"Crystal Skull ......"

Zhang Yang was shocked, he didn't expect that there was a crystal skull here.

This crystal skull seemed to be alive, his eyes emitted a light, like a scanner, scanning Zhang Yang, and said: "Name: Zhang Yang, gender: male, genetic code MH8786, evaluation: unqualified ......" The crystal skull paused, and said: "According to the eighth order, when the human race is wiped out, the first order to the seventh order are all invalid...... Commencement of the Ninth Instruction ......"

Zhang Yang felt that his body was about to explode at this moment.

Because the Ninth Directive is a domineering directive, even the people who designed it could not have imagined that this directive would take effect.

The ninth directive is fusion.

In a moment, the crystal skull disappeared, and Zhang Yang's skull began to turn into a crystal texture.
