Zhuoya said: "Understand, Zhuoya will definitely be able to think of other ways, you can rest assured, Teacher David." ”

David said, "Okay, we'll pack up our things later, and we'll go back to the ground together, and I'll walk to the security checkpoint at Base 1 by myself, while you two leave quickly, and run as far as possible." ”

Muma said: "Can you please ask Mr. David to wait near the checkpoint for a certain amount of time, such as three days, or five days, when Zhuoya and I run as far as possible, and you will reappear." We can dig a tunnel near the security checkpoint, where we can help you dig a temporary hiding hole to ensure that you are not threatened by other animals. ”

David thought for a moment and said, "Okay, after all, the sky is full of human satellites now, and if I show up early, as soon as they analyze the trajectory of your escape, you will be easily found by them." ”

Zoya said: "Don't worry, Zoya will take Muma to some underground river or cave group or something, and then escape underground, so that it will be difficult for satellites to find our traces." ”

Next, the two monkeys and one dragon began to pack their belongings, and followed the underground tunnel dug by Zhuoya to the ground more than three kilometers away from the security checkpoint of Base 1.

Here, Zoya dug a small cave for David, covered with thick animal skins, and stored David's quaint microscope, as well as enough food and water to live there for a week.

As for the exit of the tunnel, Zoya and Muma set up a simple wooden pulley and lever set, so that David could easily push away a large rock covering the exit with the pull of a rope.

After everything was arranged, Muma and Zoya said goodbye to David and turned back to the depths of the tunnel, as for where they would dig another tunnel and in which direction, it was unknown to David.

After staying alone in the small cave for more than a week, David, who was hungry and thirsty, finally couldn't help it, pulled a rope under the cave entrance, let the pulley and lever set push away a large stone weighing more than ten catties, and let the sun of Proxima Centauri shine into the cave.

After his eyes adjusted to the bright light, David picked up a branch taller than his own body and crawled out of the hole.

At one end of this branch, Muma had previously tied a piece of animal skin the size of a human palm, and since the inside of the animal skin was white, David looked like he was holding a white flag.

As soon as he walked in the direction of the security checkpoint at Base 1 with the "white flag" for a few minutes, a micro-drone suddenly appeared in front of David, hovering about fifty centimeters in front of him.

David immediately dropped the branch and said, "I'm David, please report to Station Master Misu immediately, I'm back again." ”

After a while, a small light on the belly of the micro-drone began to flicker green regularly, and David took a closer look and found that it was Morse, which meant: "Okay Mr. David, the stationmaster Misu said please wait a minute, he will come to pick you up in person." ”

After a while, a six-wheeled armored vehicle roared out of a large metal door that had just been opened at the security checkpoint wall of Base 1, and rushed all the way to David.

When the armored car came to a stop, the horn on the car sounded Misu's voice: "Dr. David, is it really you?" It's just wonderful. I'm Misu, thank you so much for remembering me. ”

David sat on the ground and said, "Please give me some water to drink first, I haven't drunk water for more than a day, and now I'm so thirsty." ”

"I'm really sorry, but according to the security check, I have to check your belongings and brain before I can come out and give you water to drink," Mi Su said. ”

At this time, Joseph's voice also sounded through the horn of the armored car: "David, my good brother, is it really you?" ”

David lowered his head and said, "Hehe, I actually alarmed our Commander Joseph, I am really fortunate in my three lives." ”

Joseph said: "Brother David, I just heard you say that you haven't drunk water for more than a day, but we do have safety regulations now, I don't know if you are willing to accept the security check of Mr. Misu." By the way, you may not know that in order to ensure the safety of the brains of the people on the base, we have stipulated that everyone, including every member of management, must undergo a comprehensive security check before entering the base, including the security of all items on their body, as well as the security of the brain. ”

David said, "Well, I know all of that. ”

Joseph said, "Huh? How did you find out about this new regulation? Do you have the equipment to eavesdrop on our conversations? ”

David said, "Since I am willing to come out, I will accept your security check, but I also ask you to swear in the name of love and peace not to alter my soul." ”

Joseph said, "Well, you know this, Brother David is really amazing. ”

David said, "As for how I know, I will tell you later, that I am very thirsty and hungry now, so please swear quickly." ”

Joseph said, "Okay Brother David, I swear in the name of love and peace that we will never alter your soul. ”

David said, "Thank you, Joseph, then please order a security check on me." ”

Joseph said: "Okay, Brother David, Mr. Misu, please go through the security check on Brother David." ”

Mi Su said: "Okay, the micro drone that is in front of Mr. David, scan Mr. David's brain first." Also trouble Mr. David to close his eyes. ”

David said, "Okay. ”

With that, close your eyes.

Feeling the breeze raised by the micro-drone blowing on his forehead for a few seconds, David opened his eyes, tilted his head and thought hard for a while, and said, "Thank you for not modifying my soul, so can I drink water now?" ”

Mi Su sat in the car, glanced at the data projected in front of him, and said: "After computer scanning and analysis, it can be confirmed that Mr. David has no ill will towards the people in our base, or even to all mankind. However, there are still a few steps, please be patient with Mr. David for a while. A small mechanical dog for security checks, please go out and search Mr. David's belongings. ”

Soon, a small side door of the armored car opened silently, and a small mechanical dog with a modified head similar to a metal cover similar to a semi-encircled "helmet" than other small mechanical dogs, jumped out of this small side door, walked to David's side, and then stretched out two mechanical hands from his abdomen, and began to touch the soles of David's feet and reach the top of David's head.
