Indeed, it is very difficult for an interstellar king's tower to explore the interstellar coordinates of another country, and sometimes it takes a long, long time, months, years, or even decades. But sometimes it is possible to find a lot in a strange row, without regularity and without skill.

Since the establishment of Noah City, the King's Tower has only explored the "primitive tribal country", and other countries have either issued their own coordinates, such as the old king, or the allies Zhong Xueqi have shared it, such as the "Religious White City". To explore the new Star King coordinates on your own, the time is immeasurable. Sometimes it may take a few years!

"That king used to have some friendship with the old king, and we also accidentally met in the intelligence area, she only has bronze level 2, but she has explored a bronze level 4 star king. Because of the disparity in strength, she decided that she had no way to capture the other party, but she was worried that the bronze level 4 king she had explored might be detected by others, and then merged, resulting in the invalidation of the coordinates she had finally explored, so she was in a hurry to sell this coordinate in exchange for the star source stone she urgently needed! ”

"Got it! By the way, are you trading over-the-counter or confidential in-house? Will this guy sell this coordinates to anyone else? ”

"The secret room transaction, although the exchange deducted a certain fee, but the transaction is one-way, we obtained this bronze level 4 king coordinates, and her king tower was cleared of all records of this coordinate."

"Don't worry, Your Majesty! The interstellar exchange is also about rules, if any interstellar king dares to violate its conventional rules, he will be blacklisted on the exchange, and he will be banned from entering the exchange forever, then he will not be able to exchange for the resources that his kingdom wants, which is quite fatal for the majority of interstellar kings. ”

"That's right!" Lu Feng nodded and said, "The bronze level 4 interstellar kingdom is one level higher than Noah City, I am quite looking forward to it, what kind of kingdom will I encounter this time?" ”

"But Your Majesty, you can't go to other countries yet, because your injuries haven't fully recovered!" Lan Weiwei on the side deliberately said angrily, and Ling Yan next to her also nodded in agreement.

"Okay, I'll take care of my body first, and by the way, take advantage of this period of time to familiarize myself with that mercury liquid armor!"

In the next week, Lu Feng practiced the mysterious liquid armor in the king's virtual reality training room, and the genetic research and development team led by Fang He made every effort to overcome the light green virus that was infected in the old kingdom at that time, which was the initial virus of the biochemical kingdom, and the difficulty of overcoming it may be relatively lower than that of the red virulent virus.

It is said that after a long period of testing, Noah City's new type of intelligent combat arms will be born and put into assembly line mass production and battlefield actual combat.

Time flies very fast, and although life is a bit monotonous for the people of Noah City, everyone is racing against time and trying to move forward.

"Boom ————————!"

A dark blue King Star Gate opened in front of Lu Feng again, and this time, he and Ling Yan set off together to spy on that Bronze Level 4 country. Because of the danger of the previous times, Ling Yan resolutely stated that he would accompany Lu Feng to carry out this espionage mission this time, at least if he encountered danger, he could also assist his own king remotely.

And if the country's Star Source Stone reserves are sufficient, Lu Feng can gather 30,000 Star Source Stones, upgrade Noah City to Bronze Level 4, and master the relevant level of technology.

"What kind of country will it be this time?" Lu Feng was full of anticipation and walked in with Ling Yan.

As the King's Gate closed, the two found themselves in the dark sewers of a city, and a group of rats came out to forage for food, and when they saw a human suddenly appearing, they fled in all directions in panic.

The two of them walked up the damp staircase of the sewer to the top of the city, a medieval-style city in Western Europe, where Lu Feng and Ling Yan were located, just like the crowded market, a bit like the bazaar in Game of Thrones, full of first-class people in burlap and scattered nobles and noble ladies in gorgeous silks.

Fortunately, Lu Feng has also done a few times of king spying, and he has accumulated a certain amount, and he happens to be wearing an ordinary coarse cloth coat, which does not look too unusual here. And Ling Yan was wearing a black coarse linen dress with a hood, wrapping her whole villain tightly, otherwise she would appear on the street with her appearance, which would be too eye-catching, and would inevitably attract unnecessary attention and trouble.

At this time, the bazaar is at the peak of the transaction, the crowd is surging, the river is endless, the hawkers' shouts, the coachman's driving, the voice of the wind and dust girl's solicitation, one after another, endlessly, it seems to be extremely lively and prosperous, although the gap between the rich and the poor seems huge, but it can be seen that the population base of this city seems to be not small.

"It seems to be a populous country! But if the standard of living in the Middle Ages is still retained, how can you achieve the national strength of Bronze Level 4? Lu Feng observed as he walked, and said curiously in his heart.

Ling Yan also shook his head suspiciously!

"Get out of the way! Get out of the way! ”

At this time, in front of the wide road in the downtown area, a group of people appeared in black pressure, and the three leading three were riding fat war horses, which should look like an army, all dressed in black. But what puzzled Lu Feng was that the weapon in their hands turned out to be an iron scimitar.

"Cold weapons?! How is this possible? Bronze level 4 countries actually use cold weapons to arm their armies? Lu Feng continued to wonder.

That group of people had already come this way, and the first few began to shout loudly, trying to disperse the crowd, and only then did Lu Feng see that these people seemed to be escorting some people.

More precisely, a group of women!

Most of these women were about twenty years old, very young, all of them pale, looking a little malnourished and emaciated, and even a little desperate and resentful!

Their hands were bound by a long rope, like a long dragon, and there were at least a hundred of them, and they staggered forward with the horse caravan.

The citizens who came by the side seemed to be accustomed to seeing this kind of scene, and even some men even pointed at the girls who were tied up, as if they were admiring a walking commodity.

"It's a slave girl!" Ling Yan said, "And there seems to be a lot of them." ”

"It seems that this is a slave trading country!" Lu Feng said.

The two of them squeezed out of the crowd and continued to walk towards the downtown avenue, and after a few steps, a dull roar of beasts suddenly came from ahead.

As soon as the crowd heard this long, dull voice, they panicked in an instant, and each of them panicked and withdrew to both sides of the avenue, as if they wanted to quickly make a spacious space in the middle of the market.

And Lu Feng and Ling Yan, who finally managed to squeeze out of the crowd, were once again forced back by the fierce crowd.

I saw that in the distance of the horizon, at the end of the big bazaar, the figure of a giant beast, about one or twenty meters high, appeared at the place of sunset, and the shadow was pulled up, as if covering the entire avenue.
