Doka Fifteen Plus Twelve said, "Yes, but not as long as here. According to the records in the history books, it is probably tens of thousands of years later. ”

Zhang Qian said: "What about black people, or brown people? ”

Doka fifteen plus twelve said: "It is also tens of thousands of years later than here. ”

Zhang Qian said: "At different latitudes? ”

Doka fifteen plus twelve said, "Yes." ”

Kyoko said at this time: "Well, I estimate that the yellow race is the ancestor of the white race, black people, and even brown people, because of the difference in latitude, light and temperature, which leads to changes in skin color, etc. ”

Zhang Qian glanced at Jingzi and said: "There is no conclusion on the earth, and the human race here has developed for tens of millions of years, so it is even more difficult to make a conclusion." ”

Doka 15 plus 12 said: "The mainstream view of us historians and biologists is indeed the same as that of Kyoko. ”

Kyoko showed a smug look and said, "Hmph, I finally won you once." ”

At this time, Doka Fifteen Plus Twelve tilted his head and said, "Okay, let's go over right away." ”

Zhang Qian said: "What's wrong? ”

Doka fifteen plus twelve said: "Sister Twenty told me that the top officer of one of our one-star intelligence departments has just finished a meeting and has an hour and a half to spare, and wants to invite you to talk to him. ”

In one of the stars and two of the stars, the planet rotates in one circle, calculated according to the earth hour, it is 26 hours, so here, an hour is equivalent to about 55 minutes of the earth, but after translation, in order to facilitate the understanding of parents, it is called double star time, also referred to as hours.

Zhang Qian said: "Okay, compared to the shock brought by this ruin, I hope that your supreme commander will give me a greater shock." ”

Soon, the three of them boarded a shuttle-shaped spaceship and arrived at the large building where they had met with Omega Eighteen and Twenty.

Following Mica Eighteen plus Twenty and Doka Fifteen and Twelve, Zhang Qian and Kyoko came to an empty house.

At this time, Micah Eighteen Plus Twenty said: "Wait a minute, our chief will come over soon, because my rank and that of the Twelfth Brother are not qualified to hear this secret, so we will wait for you outside." ”

After saying goodbye to Mica Eighteen Plus Twenty and Doka Fifteen Plus Twelve, Zhang Qian and Kyoko sat on two large white soft single sofas that appeared out of thin air, and drank tea on the white suspended coffee table in front of them for a while, and the wall in front of them automatically opened a circular opening.

A young man of yellow race with a black flat head, a gray jumpsuit and black boots walked into the house.

"Hello two guests from afar."

The young man was very self-acquainted, waving his right hand, as he walked over to the coffee table and sat down.

Of course, before he bent his knees, there was also a large sofa under his butt out of thin air.

Zhang Qian smiled and said, "Hello, leader." ”

Kyoko also smiled and said, "It seems, that, you are at least 10,000 years old." ”

The young man smiled and said, "It's really an old fellow, but it's not that old." Let me introduce myself, my name is Mio Eight Plus Seven, and you can call me Seventh Master. ”

Zhang Qian said: "You are not a soldier? ”

Mio Eight Plus Seven said, "No, I'm a civilian official, but the soldiers here are helping me with my work. ”

Zhang Qian said: "We have also asked the twentieth sister and the twelfth brother who should have asked before, so I hope that this meeting can get straight to the point and tell you that big secret." ”

Mio Eight Plus Seven said, "I have thought of one place, then, we will start?" ”

Zhang Qian nodded and said, "Please." ”

Mio Eight Plus Seven said: "The development of our twin stars, as you have seen, has achieved a super civilization, and the science and technology and culture are unprecedentedly high, and the highest known in the universe. But in the past few hundred years, everyone has encountered bottlenecks, whether it is materials science, energy science, etc., it has almost stagnated. This is not because we don't work hard subjectively, but because of the objective laws of the universe, our exploration of our own planet and the universe has lasted for tens of millions of years, and it is already difficult to raise it to a higher level, but there is a team of scientists, to be exact, a team of scientists in two of them, who have gone the opposite way and begun to study the potential of human beings themselves. ”

Seeing Mio Eight Plus Seven pick up a water cup that had just floated over and drink water, Kyoko interjected: "7 Three 1 troops? ”

Mio Eight Plus Seven was stunned for a moment, and said: "I haven't studied your earth like twenty and twelve, I'm sorry, or your memory, so what are you talking about troops?" ”

Zhang Qian said: "It is an evil army that likes human experiments, or research institutions, that have committed heinous crimes against all mankind, and they are not as good as animals. ”

Mio Eight Plus Seven said: "That's not it, no matter how bad the people on the second star are, I guess they shouldn't be as bad as you say." ”

Zhang Qian said: "Also, no matter how bad it is, no one can be too bad for them, and they have a good life." ”

Jingzi pouted and said, "Let's listen to the leader and continue, that, don't get entangled in the previous things." ”

Mio Eight Plus Seven said, "Okay, I'll continue. The scientific research team of the two stars has conducted long-term research on the potential of human beings by using the knowledge of the microcosm and the science and technology they have mastered, and has discovered a substance. Before explaining this substance, let me explain that the human brain secretes different substances under certain circumstances, such as sadness, joy, and anger, and these microscopic substances can even affect all aspects of the body's blood and even muscles, do you understand? ”

Zhang Qian said: "I know, it's similar to dopamine (paraphrased) or something. ”

Mio Eight Plus Seven nodded and said: "Yes, but this substance or element is ten thousand times smaller than the chemical element dopamine, and the cause of its production is that when people do good deeds or help others, they get a sense of self-satisfaction, and at this time the brain will produce an element, and the scientists who discovered it named it the good element, as the name suggests, it is an element produced by good people." ”

When Zhang Qian and Kyoko heard these words, they made expressions of sudden realization at the same time, and at the same time, their bodies relaxed at the same time and leaned back on the back of the sofa chair.

At the moment when Mio Eight and Seven drank water, Zhang Qian said: "I understand, no wonder Dongge and the Twelve Brothers are very interested in the subject of human morality, it turns out that it is for this good element!" ”

Kyoko also said, "Yes, that, whoever has morality will master the element of goodness, is that what it means? ”
