After all, the records of the fifth-level civilization in the history of their civilization, as well as the information purchased from the Ming Empire, show that generally speaking, the personal lifespan of the fifth-level scientific and technological civilization in the universe is generally about 500 to 600 years, and even if there are some special races, their lifespan will generally not exceed 1000 years.

Before, the Swan civilization thought that the lifespan of the Ming Empire was the same as that of the general fifth-level civilization, and it was also about 500 to 600 years, if this was the case, Princess Tianfeng's lifespan was comparable to that of the average person in the Ming Empire, so it was okay to marry, but now when he heard that Zhang Haitao's lifespan was at least 1500 years, and with the deepening of the degree of cultivation in Zhang Haitao's mouth, its lifespan would increase.

So if the facts are really what Zhang Haitao said, then it is impossible for the two of them to be combined, and the lifespan of the two is too far apart.

Zhang Haitao raised his head to look at Princess Tianfeng's gloomy eyes, so he said, "Tianfeng! What's wrong, is there anything on your mind? ”

Princess Tie Feng cleaned up her mood for a moment, and then replied, "It's okay, it's just that I thought of some unpleasant things." ”

"There's just a sentence I don't know whether to say or not." Princess Tianfeng hesitated for a moment but then spoke.

"That's the case, your civilization of the Ming Empire, what do you think about marrying a civilized woman outside the Ming Empire, or whether the laws of the Ming Empire prohibit it."

"There is no explicit prohibition in this regard, the Ming Empire just can't marry a wife, and there are no other regulations or prohibitions." Zhang Haitao replied.

Hearing Zhang Haitao's words, Princess Tianfeng's eyes dimmed again, it was obvious that he and Zhang Haitao were impossible, as the princess of the Swan civilization, it was obvious that it was impossible for him to marry someone from other civilizations as a concubine.

After all, this is a matter of the face of the entire Swan civilization, once the princess of the Swan civilization is married as a concubine by people from other civilizations, then what will people of other civilizations in the Ocean of Light think of the people of the Swan civilization.

After dispelling this idea, Princess Tianfeng's face suddenly straightened, and then said to Zhang Haitao: "Mr. Haitao, let's not talk about this, let's get down to business first, this is also the purpose of our invitation to you tonight."

I don't know if your Ming Empire came to trade in the Ocean of Light this time, doesn't it have any other purpose?

After all, your civilization trades in the Ocean of Light, and most of the money sold is munitions, which will definitely upset the balance of Xie You in the Ocean of Light, leading to war. ”

"I don't know how much you know about the fifth-level civilization, princess, how much do you know about the strength of the fifth-level civilization, and how much do you know about the strength of the Ming Empire." Zhang Haitao did not answer the words of the Swan princess directly, but asked him rhetorically.

"Mr. Haitao, our civilization is not ignorant of the fifth-level civilization in your mouth, after all, our Swan civilization is also an ancient civilization, with a history of hundreds of thousands of years, so we still know something about the fifth-level civilization.

According to the records, the fifth-level civilization is very powerful, especially for civilizations below the fifth level. But the fifth-level civilization is not invincible.

At best, the fifth-level civilization is only their technological level, which is more advanced than the fourth-level civilization, and the space warships they make are even larger and more powerful than the fourth-level civilization.

A spaceship of the same level, the combat effectiveness of a fifth-level civilization spaceship is far from being comparable to that of a fourth-level civilization, and in addition, the territory, heritage, and potential of a fifth-level civilization are not comparable to that of a fourth-level civilization.

But even so, as far as I know, the fifth-level civilization is not invincible, not to mention that there are still some sixth-level civilizations in the galaxy in our records, and these civilizations are definitely much more powerful than the fifth-level civilization.

In fact, there are many fourth-level civilizations in the galaxy, and their own strength is not much weaker than many fifth-level civilizations, but because these civilizations do not have warp engine technology, they cannot be promoted to fifth-level civilizations.

Take our Swan civilization as an example, in historical records, in the past, the strength of our Swan civilization was not much worse than the average fifth-level civilization, but after so many years, now our Swan civilization has a wider territory, a more powerful war ring, and a larger population, so I think the current Swan civilization is not weaker than the fifth-level civilization.

What's more, the space warships of our civilization now already have the protective cover technology that only fifth-level or even sixth-level civilizations can have, and the speed of the spacecraft has also been qualitatively improved, and the fastest speed has been able to reach the level of fifty or sixty percent of the speed of light.

In addition, our civilization, it should be said that the eight major civilizations and the two overlords in the entire Ocean of Light are already capable of building spaceships of more than 10 million tons, so I think that our Swan civilization is definitely not worse than the fifth-level civilization.

For Mr. Haitao, the Ming Empire where you are located, I think it should be a very powerful fifth-level civilization, not to mention Mr. Haitao, your two giant battleships, even those space battleships you sold to us, I think it is definitely not an ordinary fifth-level civilization that can be manufactured, let alone those two giant warships, so I think the Ming Empire is by no means an ordinary fifth-level civilization. ”

Zhang Haitao looked dumbfounded at Princess Tianfeng where Wang Po sold melons and boasted about her civilization, and even praised the eight civilizations and the two overlords in the Ocean of Light by the way, after all, the Ming Empire is also a foreign civilization anyway, so the Swan civilization, as a member of the Ocean of Light, naturally wants to exaggerate the strength of the Chinese name of the Ocean of Light.

Of course, if it is an ordinary civilization, you will think that what Princess Tianfeng said makes a little sense, but for Zhang Haitao, he does not agree with Princess Tianfeng's thoughts, after all, Zhang Haitao is a soldier of the Ming Empire, and the Ming Empire is a fifth-level civilization, so his understanding of the fifth-level civilization is definitely not comparable to Princess Tianfeng.

After all, Princess Tianfeng, she didn't have the power of a fifth-level civilization that she had seen with her own eyes.

"Princess! I can only say that you are too naïve, if you are just an ordinary person, I have nothing to say about your opinion, but as a princess of the swan clan, then I must say that the fifth-level civilization is powerful, lest you encounter an inorganic civilization in the future and suffer a big loss.

I won't talk about the rest, let's talk about the weapons of mass destruction of the fifth-level civilization, in fact, this is also one of the important symbols of the fifth-level civilization, weapons of mass destruction can definitely represent the highest level of science and technology of each civilization, and scientific achievements. ”
