And because of the particularity of the Ocean of Light, there is a lot of information that the Ming Empire still has not sold, of course, this is enough for Princess Tianfeng.

And due to the closed nature of the Ocean of Light, except for the part purchased for the Ming Empire, all the other information sold by the Ming Empire is true and effective information, and there is no false information at all, so even if the civilization in the Ocean of Light buys this information, there is no need to worry that the information of the Ming Empire is fake.

Because it is impossible to go beyond the Ocean of Light without warp engine technology in the Ocean of Light, even if the civilizations in the Ocean of Light know this information, it will actually be of little use to them.

But even so, in fact, this information is still very important to the civilizations in the entire Ocean of Light, after all, the Ocean of Light is too closed, and the civilizations in the Ocean of Light cannot obtain information about other civilizations in the galaxy from other channels, and even most civilizations do not even know the most basic civilization hierarchy in the universe.

Although the Swan civilization is much better than other civilizations, after all, the Swan civilization is also a relatively old civilization in the Ocean of Light, so it still knows some more secret things, but this is only limited to knowing the iconic technology of the fifth-level civilization, the warp engine technology, and the others are not known, let alone the sixth-level and above-level civilizations.

Therefore, when Princess Tianfeng, who was named in the Heavenly Civilization, saw this information, the idea of buying this information suddenly appeared in his heart, but at this time, because Princess Tianfeng was still in space and had not returned to her own civilization at all, she could not buy this information at all.

So Princess Tianfeng had no choice but to continue watching.

After reading the information class, the first thing Princess Tianfeng saw was the various industrial products of the Ming Empire, because the people of the Ming Empire are very similar to the people of the Swan Clan, so the various industrial products designed by the Ming Empire are not difficult to use for the Swan Civilization at all, after all, the Swan Clan just has one more pair of wings than humans, so things like machine tools have no obstacles at all in terms of operation habits.

After seeing the machine tools of the Ming Empire, she couldn't help but get excited, the industrial products of the Ming Empire are very important products for the swan civilization, because these machine tools and other equipment are quite high, compared with the industrial products of the swan civilization and the industrial products of the Ming Empire, the gap is not one or two points, although the swan civilization and the Ming Empire are only one level of civilization difference.

But Princess Tianfeng could feel that the gap between the civilization they were in and the precision level of these industrial products of the Ming Empire was no longer a civilization level, and it was definitely more than a civilization level.

Although Princess Tianfeng really wanted to buy these industrial products of the Ming Empire, she still didn't have a Ming Empire's energy coins at this time, so she couldn't buy these products at all.

However, Princess Tie Feng still marked the things she wanted to buy first, and waited until she returned to her own civilization and discussed with the high-level of the civilization before making plans, and he was sure that there were more things she wanted to buy under the list of the Ming Empire, after all, such a long list was enough for her to look at it for a long time.

However, he could also see that the Ming Empire was not in a hurry at all, because after the Ming Empire sent the list over, it had already been explained that he should take a closer look, after all, there were so many commodities in it, and it was absolutely very thick to find the things they needed for civilization.

And these things, the ship's brains can't help them at all.

After that, it's the weapon class, the Ming Empire is currently divided into three levels in the current five periods, the first level is the basic level of weapons, according to the method of dividing weapons by all civilizations in the ocean of light, the so-called basic level weapons of the Ming Empire, in fact, are lightweight weapons in conventional weapons, such as weapons with a caliber of 300 mm that are all classified by the Ming Empire as basic weapons.

Electromagnetic railguns, laser cannons, particle cannons, optical magnetic cannons, shaped cannons, photon cannons, etc., there are more than a dozen types of basic level weapons alone, which is definitely beyond the imagination of Princess Tianfeng, after all, even if the swan civilization belongs to an old fourth-level civilization in the entire Ocean of Light, it is also one of the best existences in the entire Ocean of Light, but there are only a few types of conventional weapons.

The second level of weapons is some heavy weapons, such as weapons with a caliber of more than 300 mm, but most of these weapons can already be used as the main guns of most civilization capital ships in the Ocean of Light, and there are also some space fighters and small spaceships produced by the Ming Empire, as well as some land combat weapons.

And the last level of weapons, called the destruction level by the Ming Empire, each of these weapons can easily destroy a planet, and the most powerful of this level of weapons is the space battleship produced by the Ming Empire.

These weapons are very attractive to Princess Tianfeng, after all, if every civilization wants to survive in the universe, then force is definitely the top priority, after all, the laws of the universe are so cruel, the weak eat the strong, if you want to protect yourself, you must have strong force.

In the following days, Princess Tianfeng waited to check the list of goods provided by the Ming Empire, and marked all the things she wanted to buy, and then stored them on her spaceship Zhi Brain.

"The list provided by your civilization is very detailed, but I don't think I need to say more about my current state, so I have to return to the location of my civilization and discuss with the high-level in the civilization before I can make a decision, after all, although I am the princess of the swan civilization, there are many things that I can't make a direct decision, after all, I am not the emperor of our civilization, and even the emperor can't make a decision on some things, after all, the price of these goods is too high."

After seeing the information sent back by the princess of the Swan clan, Zhu Lei was not in a hurry, after all, he also knew very well that Princess Tianfeng had no ability to buy these goods at this time, and the reason why Zhu Lei gave the list to Princess Tianfeng was that he planned to trade with the Swan civilization where Princess Tianfeng was located, not with Princess Tianfeng personally.

"Alright, we're waiting for your good news, and if your civilization decides to make a deal with us then, then contact us directly."

"Hello, respected Ming Empire's civilization trade fleet, that's the case, I plan to return to our civilization now to discuss this matter with the high-level of our civilization, but I want to invite your fleet to our civilization as a guest, please ask if your civilization is willing."

In fact, Princess Tianfeng was worried that other civilizations would be in contact with the trade fleet of the Ming Empire, and took the lead in trading with the Ming Empire, after all, the Ming Empire noted on the trade list that there were many technologies in the entire Ocean of Light that would only be sold to one, and would not be sold to other civilizations, so she was afraid that other civilizations would buy these technologies.
