You must know that Vina is a sixth-level civilization! And this Mr. Zhang is a citizen of the Ming Empire, a fifth-level civilization, but even so, it seems that his lifespan is far beyond that of Vena, and this person does not surprise her.

And he knew that this Mr. Zhang was not a rich man in the Ming Empire, he was just a small civil servant, that is, the most basic official of the Ming Empire, not even an official, just a staff member at the lowest level of the government.

However, even if this Mr. Zhang is the lowest civil servant of the Ming Empire, he can enjoy this kind of technological products that prolong life or preserve appearance, which gives her a deeper understanding of the strength of the Ming Empire, and Vena's intuition tells him that the product used by Mr. Zhang is a drug or technology that can greatly increase lifespan, not just a technology or drug that preserves appearance, after all, no matter how much the appearance changes, it cannot change the aging of the body function itself. And these things will be presented on the surface of the human body, and these are the ones whose appearance can still be seen no matter how much they change.

After all, changing the appearance is only a superficial thing, not an essential thing, after all, it is difficult to draw the skin and bones, and the aging of the body function is not at all covered up by the change of appearance.

After all, there are many technologies in the galaxy that can delay the aging of appearance, and there are many technologies that can change appearance and even retain appearance, and it can be done after the general civilization level reaches level five, but it is extremely difficult to delay the passage of life, in fact, the improvement of civilization level is also the improvement of life and lifespan, and now the life growth technology of the Ming Empire has reached this point, and it can even bring together every citizen of the Ming Empire, you can imagine how powerful the life technology of the Ming Empire is.

At this moment, even Vina has the urge to become a citizen of the Ming Empire, after all, it is a technology that can greatly extend the life of the country, after all, he thinks that this kind of technology will definitely not be sold to the outside world except for the Ming Empire's own nationals.

And even if it is sold to the outside world, the technology of the Ming Empire may not be suitable for other civilizations in the galaxy, after all, the genes of each civilization are different, the civilization is different and the race is different, and the technology developed by his own civilization is generally developed for his own civilization, and other civilizations may not be able to use it, especially these life technologies, especially these life technologies, thinking of these, the impulse in his heart was dispelled by himself.

After all, if these technologies are useless to him, then even if he joins the Ming Empire, it will not be able to extend his lifespan, after all, the Ming Empire will definitely not develop a technology specifically for him.

At this moment, Vena is really very envious of the people of the Ming Empire, the citizens of the Ming Empire can enjoy this technology even if they are ordinary people, you must know that such a thing is not even in the galaxy, you must know that according to the observation, the life expectancy of ordinary people in the Ming Empire must be very high.

"Lady Vina, welcome to you, it's a pleasure to have you here again. I will navigate for you and ask your fleet to follow my ship. ”

"Okay, Mr. Zhang."

Then Vena followed him towards the Ming Empire's interstellar trading port near the Blue Dragon Star.

At the same time, the Qinglong Star in the Ming Empire is paying attention to the situation here at any time, and at this time, the alert level is still above the yellow, and the military strength of the Qinglong Star is ready to deal with emergencies at any time.

Although the Ming Empire thinks that although the twelve warships of Vena and his have reached more than three hundred kilometers, the threat to the Ming Empire is not great, but the necessary vigilance is still necessary, not to mention that at this time, the Ming Empire's control over the entire star field is not very strong.

You must know that the Ming Empire has controlled this star field, and it has actually only been more than a hundred years now, not to mention that this star field has a distance range of more than one hundred and fifty light years, so it is difficult to draw a tiger's skin and bones, and it is difficult to know the face of the person but not the heart, although Vena has already traded with the Ming Empire, and it was still near the Kara galaxy not far from the solar system at that time.

However, at that time, the Ming Empire had no choice, after all, the territory of the Ming Empire was only so large at that time, so it could only put the interstellar trade port near the Kara civilization, but now it is different, the Ming Empire has a vast territory, and there is no need to put the solar system, the birthplace of mankind, in a very dangerous situation.

In fact, this is also the source of the contradiction between the Ming Empire and the Black Bear Civilization, after all, the wormhole near the Kara Galaxy is only a dozen light years away from the solar system, and such a distance is simply close to a fifth-level civilization.

If there is no existence of this wormhole, there may be contradictions between the Ming Empire and the Black Bear Civilization, but it will not be to the point of life and death like now, after all, although the Ming Empire is strong now, the Ming Empire is not an unreasonable country.

But with the existence of this wormhole, then the threat of the black bear civilization to the Ming Empire is different, you must know that the black bear civilization is a fifth-level civilization, and it is a very belligerent fifth-level civilization, so it is absolutely impossible for the Ming Empire to compromise with the black bear civilization.

What's more, it is impossible for the Black Bear Civilization to compromise with the Ming Empire and hand over the control of this wormhole to the Ming Empire, which will have a very adverse impact on the security of the Black Bear Civilization.

After all, no matter what, the black bear civilization is also a fifth-level civilization, and their civilization is a civilization with a long history and has its own pride, so there will definitely be a war between the Ming Empire and the black bear civilization, which is a fact that no one can change.

However, there is one thing that the two civilizations are very clear, because the two civilizations are both fifth-level civilizations, no matter who wants to completely eliminate them, on the other hand, it is actually impossible, although the current Ming Empire is temporarily ahead of the Black Bear Civilization in terms of scientific and technological strength, but in terms of overall military strength, the Black Bear Civilization is definitely ahead of the Ming Empire.

Even if the civilization level of the Ming Empire is now promoted to a sixth-level civilization, it is impossible to completely make the black bear civilization disappear into the universe, this is the confidence of an old fifth-level civilization.

And the Ming Empire is not comparable to the black bear civilization in terms of scientific and technological strength, of course, they don't know about this black bear civilization, they just think that the Ming Empire is no different from an ordinary fifth-level civilization, although on the surface it seems that the spaceship of the Ming Empire is much stronger than the spaceship of the black bear civilization.

However, this does not mean that the technology of the Ming Empire is definitely more advanced than that of the Black Bear Civilization, after all, each civilization has its own unique technology, and the Ming Dynasty alone with spaceships is nothing.
