Higher hardness? Weightlessness and loss of pressure on the moon means that greystone will be heavy on the moon. A trace of sand leaked from the top of the cavern, and sand and dust from the surface of the moon spilled off.

Chen Ba's voice sounded in the mine again, "There is a certain probability that there will be companion organisms around the gray stone, gray crystal, which is a high-density and high-quality energy body, once it is found, it must be handed over. All students who turn in will receive 500 points. ”

The crowd began to exchange ears.

"500 points? A limestone crystal? ”

"It's a bit hard."

"If you really dig it, you can send it."

Zhou Kun glanced at An Lina and did not speak, now there is only one goal to dig the corresponding amount of gray stone to complete the task and enter the next stage. This mine gave him an inexplicable depression.

There was a rattling sound from the top of the mine.

An Lina's efforts didn't seem to be of much use, the gray stone seemed to be inexhaustible, and even with the help of tools, it still grew firmly on the cave wall.

I don't know how long it took, but I finally felt some loosening, and Zhou Kun and An Lina were more energetic. Soon the perimeter of the greystone was emptied, and one tip was exposed, and the innermost end was columnar.

Zhou Kun and An Lina looked at each other and smiled, this is the first piece? However, this piece seems to be undug up, far beyond Zhou Kun's expectations, what is this digging up? An Lina activated the detector, and soon the numbers were displayed on the detector, and the data showed that there were still 30 to 40 centimeters, and there were two segments in between.

Could it be that two were dug at once? Zhou Kun smiled. However, the magic has just begun, and someone in the mine has shouted, "Found it." ”

"Greystone has been dug up."

The man who dug up the gray stone shouted heartily.

Zhou Kun was not affected in any way, but the frequency of digging was faster.

Boom, boom. A small crystal popped up, this is a gray stone crystal?

There are no words to describe Zhou Kun's excitement.

"Put it down." An unfamiliar voice came from behind him. Zhou Kun turned around and looked, this was a student at the National Defense University, I don't know if he was excited or nervous, and his voice trembled a little when he spoke.

Zhou Kun wanted to calm things down, but the student obviously didn't want to do that. "Take it out."

An Lina turned around and glanced at the boy who was in the way of mining, "Get out." ”

Finally, the student took a step back. "If you don't hand it over, I'll report you." The student said hatefully.

Zhou Kun was a little frustrated, these are the students of a first-class military academy? What's on your head?

"I'm not kidding you, count to three and throw things over."

Zhou Kun and An Lina both felt a chill, a long knife that was extremely sharp.

An Lina didn't speak, she stood quietly, thinking about all kinds of possibilities.

Time passed slowly minute by minute, and Zhou Kun obviously felt a slight tingling pain in his back, fortunately, there was protective clothing, Zhou Kun complained in his heart. It was obvious that this man was not here to assassinate, he only wanted benefits.

The quicksand at the top of the cavern continues, but the stability is decreasing compared to before.

What's wrong? Zhou Kun was puzzled, "An Lina, An Lina, what's wrong?" ”

An Lina quickly converted the data in the backup equipment, "Is this about to collapse?" ”

"The probability of a collapse is 63 percent."

However, no one realizes this, everyone without exception is digging, time is money. Zhou Kun complained secretly on the side.

The student at the National Defense University lowered his tone and lowered his voice to warn repeatedly, "Take out the crystals, or you will bear the consequences." ”

"Are you commissioned by anyone?" Zhou Kun asked.

"Nope."

While the two sides were still confronting each other, the entire mine let out a clattering sound, "It's going to collapse." ”

Before the words could be spoken, some timid students quickly ran out of the cave.

"Let's go." Zhou Kun grabbed An Lina. "It's going to collapse."

Something kept falling from the top of the mine, and even some huge greystone was falling. At the moment, no student cared about this, and rushed out. Escape matters.

"Stop." A figure stood out of the darkness, and this was definitely not a good thing.

Zhou Kun ignored it, and at this moment Zhou Kun showed his strong physical fitness. Holding An Lina's little hand, she stepped directly over the figure with an arrow step.

"What's going on?"

Zhou Kun pulled An Lina and ran away, wanting to live.

……

"Has the show begun?"

"It's time to start. It's time for the set-up to take this opportunity to get out of the scene. ”

This can be regarded as a horse platform that intends to rectify Zhou Kun.

The backs of these people look familiar, some are Zhou Kun's classmates, and some are Zhou Kun's seniors.

"Catch him."

More people are silent, as long as they kill him, they don't have to worry about it for the rest of their lives.

Zhou Kun showed his true strength at the moment, and he was still accelerating with one hand. For the sake of the family, for the sake of the homeland. Death is chasing behind him, and Zhou Kun is on the run.

Hundreds of meters away from the exit, Zhou Kun finally pressed the energy button of the quantum protection suit.

Soon, a mysterious electric current appeared on Zhou Kun and An Lina's bodies, Zhou Kun grabbed An Lina and rushed directly towards the cave wall of Banpo, a strange feeling, it seemed that the whole body was decomposing and dissipating, and gradually formed the smallest particles. 30、29、28、27…… During the countdown, Zhou Kun and An Lina crossed the mine and came to the surface.

The two of them gasped for breath, this time it was too thrilling. Not only were there assassinations, but the roof of the cave collapsed,......

The two men ignored anyone and ran straight back to their rooms.

"What is this?" Zhou Kun smiled proudly, there were three gems in his hand. Thank God.

Then, the two of them took out all kinds of stones, this is not gray stone, Zhou Kun can see that this is a gray stone crystal, which is what Teacher Chen Ba said.

"Hide." Zhou Kun said, An Lina didn't say anything, and directly hid more than ten crystals.

Zhou Kun, who had done all this, did not settle down, and it was a little difficult for the two of them to obtain crystals and be witnessed.

Who is going to kill himself? Zhou Kun then remembered the things in the mine, landslides, assassinations, and robberies, and the objects of these people were all himself.

Wait patiently, there may be results, Zhou Kun thought to himself.

More and more students left the mine, and everyone seemed to die, and many students vomited directly. Chen Ba looked at these and frowned.

The mine was used last time, why did the problem of collapse occur? Someone must have done something, what are they going to do! Chen Ba's anger grew heavier and heavier.

Yisheng stood aside and said something to the officer behind him.

Zhou Kun stood at the window and looked out, maybe everything had just begun.

……

The corpse halfway through the mine seemed to move, and there was a strange sound. Gradually, the corpse was erected......
