Fifteen years ago, the area of Jinshan Castle formed a huge cave with no depth.

At that time, the entire city, along with the three hundred meters underground, was seized by the Mother Stone Division to the Kanda Tablet Planet. The remaining Mother Stone energy pierced through the place, creating a bottomless cavern.

A city suddenly disappears, and the huge energy fluctuations frighten the whole world.

Within 20 kilometers of Jinshan City, it is already a forbidden area.

Five kilometers outside the mouth of the cave, there are rows of buildings, and there are research institutes of Dahua that are stationed here all year round to find the truth.

The world's top scientists tried to solve the mystery, however, fifteen years passed, and nothing came of it.

Research institutions, from more than 800 scientists gathered around the world at the peak, to more than a dozen experts from Dahua with a group of people remaining.

The images scanned from the research facility are transmitted to the mothership.

Lu Dan knew two of them, one of whom was her classmate.

The caves, as a mothership base, couldn't be better.

In the middle of the night, two motherships entered the cave silently, suspended a thousand meters above the ground.

Wu Fanyang's home is not in Jinshan City, but in the north, and for the time being, he is not in a hurry to go home.

Hundreds of thousands of residents of Jinshan City have been missing, and for fifteen years, there should be no more identity information.

More than 2,000 people came with the mothership, and most of them had immediate relatives on the planet Kanda. There are more than 300 immediate relatives on Earth. How to meet your loved ones suddenly became a difficult problem.

You can't always fly a flying machine and suddenly appear in front of your loved ones, that's too appalling.

They need an identity, a reason to be missing for fifteen years.

Fortunately, to eliminate the memory of meeting, the equipment inside the mothership can do it.

Professor Han proposed a method that was approved by everyone, only to see the next generation of immediate relatives. If the immediate family members are willing to accompany the mothership to the planet Kanda, the memory of the meeting will not be erased. If you don't want to go, erase the memory of the meeting.

"Commander, I want to visit my old classmates."

"How do you think about it?"

"He won't gain anything from studying here for a lifetime, so I'll talk to him briefly. In addition, Dahua Guo and Emperor Mold are facing off, if we make a move, we need a guide, and my old classmate should have a channel in this regard. ”

Wu Fanyang thought for a moment and nodded.

The two sides faced off in an all-round way, and with two motherships, it was easy to solve the six aircraft carrier formations of the mold emperor.

Even the Mlevery Nuclear Submarine was dealt with with ease.

The coordinates of the enemy's nuclear submarine have long been scanned.

In a word, it doesn't take much effort to disarm the Mold Emperor Group.

It's just that in this way, the earthlings know that an alien super civilization exists, which will cause great panic and even great turmoil.

It is not conducive to the long-term development of the earthling human race.

The 3011 mainland terran needs a channel to communicate with the high-level of Dahuaguo.

Now, it is not only necessary to consider the interests of Dahuaguo, but also the interests of the entire earth human race.

……

……

Outside the gates of the research institute.

Several security guards looked at Lu Dan in surprise, here, there have been no outsiders here for a long time, let alone in the middle of the night.

Fifteen kilometers from the institute, it is the perimeter of the forbidden area, and a tall fence is built.

Not only are there various security facilities on the fence, but even if you enter the fence, there are at least three checkpoints along the way to the institute.

How can a woman, a person, get here quietly.

"I'm looking for Professor Tang Minghua."

"Who are you?"

"My name is Lu Dan, and I am a classmate of Professor Tang Minghua."

"Wait a minute, then contact Director Tang."

Lu Dan nodded, and the security called Tang Minghua the director, it seems that he is in charge of here.

Compound, huge.

Overgrown with tall trees.

Nearby, villas are scattered. In the distance, rows of buildings stand.

Lu Dan noticed that about fifty meters from the gate, a villa was lit up.

A figure ran out of the courtyard gate of the villa and ran towards the gate.

Inside the compound, the light is excellent.

Lu Dan had already seen clearly that it was her classmate Tang Minghua.

More than ten meters away from the gate, Tang Minghua stopped and stared wide-eyed.

"What, old classmate, don't you know me?"

"Lu Dan, it's really you...... You, you're back? ”

"Just came back."

"Good, good, good, I've been looking forward to this day for fifteen years."

"Old classmate, it's cold outside, why did you run out in your pajamas? If we freeze our Tang Da Director to death, I can't afford to bear it. ”

"Lu Dan, you are still so cheerful and funny, okay, hurry up and go to me. Captain Zhao, the security of the research institute has been upgraded to the first level, and no one is allowed to enter without my order. ”

"Yes, Director Tang, I'll arrange it immediately."

Level 1 security was the first level of security that he had only come to work here more than a decade ago.

At the time, he was a soldier here.

With no progress in the research, everything slowly relaxed.

He also retired and became the captain here.

When the first-level security is activated, the nearby public security and the military will receive the message.

Soon, a large number of security forces will arrive here.

He didn't know why the woman's arrival would trigger Level 1 security.

What he doesn't know is that when the first-level security is activated, the high-level side of Dahua will also receive the news.

Lu Dan did not stop Tang Minghua from activating the first-level security, she knew that her arrival would soon shake countless people.

……

……

"Lu Dan, I have always believed that you are still alive."

"Thank you, old classmate."

"You are the most important one among the missing people in Jinshan City, with you, one day the truth will be revealed."

"I'm not the most important one, Wu Fanyang is."

"Who is Wu Fanyang?"

"At the time of the incident, he was delivering food in Jinshan City."

"A delivery guy? How could it be the most important person? ”

"He is now the Grand Commander of the Kandabei Planet, and he is also the Supreme Grand Commander of the Human Race."

"Where is the planet Kanda?"

"Seventy light-years from Earth."

“…… So, you've found a way back? ”

"Yes, meet the super civilization ......"

"Can you elaborate?"

"I can't go into details, super civilizations also have enemies, and they can scan hundreds of light-years away. Ability to analyze all scanned information. ”

"Can you take me to the Grand Commander?"

"I'm here to invite you to the mothership."

"Mothership? Where is it? ”

"Inside the cave?"

“…… How many years is technology ahead of the planet? ”

"If we rely on the exploration of human beings on the earth, it is estimated that it can be reached in 300 to 500 years."

“…… Do you have a shortcut? ”

"No, it's a mutual effort."

"Okay, don't say much, I won't make tea anymore, I'll change my clothes and leave immediately."

"You live here alone?"

"Yes."

"Good work."

"It's worth all the hard work until you come back."

"Level 1 security activated, who can alarm the top person tonight?"

"Lead in terms of security."

"Okay, old classmate, you are very smart, you know that something big is happening, and decisively activate the first level of security."

"Lu Dan, don't praise me, at this moment, I only have one wish, to find out the truth."

"Let's go, the flying machine outside the door has arrived."

"How can I not see it."

"This is simple, the color band of the aircraft shell adjusts itself, and the human eye cannot see this band."
