"Black medicine? What is that? Glancing at Yan Yu, Su Jinyu asked suspiciously.

In fact, she had some vague guesses in her heart, after all, it was Linhai, and the most powerful weapon was probably the only one she thought.

Could it be that in such an era, there are already such weapons?

"Well, what do you say?" After all, George was just a businessman, and although he knew about it, he didn't know much about it.

"It was brought back from a foreign country by His Royal Highness the Prince, although it is very inconspicuous, but it is extremely lethal!"

"When a pirate ship approaches, our guards in charge of protection will prepare the black medicine, and when they get close enough, the black medicine will be effective."

"Throw it on a nearby pirate ship, and the guards hide behind the protective wall, and there will be a loud noise, and the ship will sink, and the people on it will hardly survive."

Describe as much as he knew, and George didn't think there was anything he couldn't say.

Obviously, this country does not, and although they have ships to go to sea, they cannot go to other countries.

So, they didn't get the source of the black medicine.

What surprised George was that although there was no source to get it, here, there was a powerful bug, that is, Su Jinyu.

Listening to his description, Su Jinyu nodded, sure enough, it was the thing she was thinking.

It's just that here it is black medicine, and in her original era, it was called ......** or firearms.

It was indeed a lethal weapon.

"George, do you know how many countries have this thing?" After thinking about it, she asked.

Although the Celestial Empire does not have it, it is not like other countries, you can go to other countries to obtain it, at least not now.

But...... She might be able to figure it out, and she wouldn't have to go anywhere else to have it.

"I don't know too much, but it doesn't seem to be much, it's basically only in countries bordering the sea."

After all, the seaside means that there may be pirates, so you have to have some means of self-preservation.

"That'...... How did you get black medicine? "It can't be for no reason, perhaps, there is something like yourself, crossed over?

Su Jinyu secretly guessed in her heart.

"I really don't know about this." Without hesitation, he shook his head directly.

Su Jinyu didn't ask any more, now that she is pregnant, she is afraid that it will not be possible if she wants to make trouble.

Perhaps, when it is only her and Yan Yu, you can go to the space to take a look, in case there is a shadow on the fourth wall, then you probably have a spectrum in your heart.

The carriage continued on, and just a little further on, it came to a small town, which was just right to settle down.

The things in the town are quite complete, the inn is also cleaned up, a simple meal, and a few people rest.

"You seem to be very interested in that black medicine." Sitting in the room, Yan Yu poured Su Jinyu a glass of water and asked in a low voice.

"Well, that thing is very powerful, if we can have it, it will be much more convenient."

Unlike George's home country, the Celestial Empire has only two towns bordering the sea.

However, due to the inconvenient access to the shore, it is surrounded by small countries, so it has always been safe.

But if it is...... On that day, I made a change, I could go to other countries to exchange goods, and I could do business with them, and the risk factor would increase.

Su Jinyu will think about it very late, so her mind will naturally be very active.

"You ......" Yan Yu looked at her, probably guessing what she was thinking at this time.

"If I have the opportunity, I am naturally willing to travel to other places, move around, and even do business, of course, you have to accompany me."

I made an agreement with Pei Yi because they also needed protection.

Now, Pei Yi has become the crown prince, and this agreement is almost over.

If he became the emperor, since Yan Yu had assisted him, how could he get some convenience, and he wouldn't have to worry about anyone bullying him and needing protection.

"I'm going to take a look at the space in the evening." There is no need to hide this from Yan Yu, the reason why Yan Yu is not allowed to go in with her is to be on guard.

Not to guard against Yan Yu, but to guard against someone coming to them, but no one could be found.

"Okay." Yan Yu nodded, anyway, no matter what, he would know what he should know.

Su Jinyu's thoughts, he has always been clear, if she is willing to accompany herself, he will accompany her.

It's just that the two people who were envisioned together used to have more children now have more of them.

Night fell, and after talking to Yan Yu, Su Jinyu entered the space.

In the space, there is never a saying that it is dark and daylight, but the light inside does not make people uncomfortable.

I drank some spiritual spring water and picked a cucumber from the space.

There are really too many benefits in the space, you don't have to worry too much about the season, and everything you plant will grow well.

Eating the cucumber, she stood at the first wall for a while, to see if anything new came out.

There was still a time when she stumbled upon this.

Even the wall that appears will change, for example, the first wall, suddenly one day, there are more seeds.

She's tried to plant it, but it didn't grow, and she's always been weird about it.

After all, the seeds planted in the space had never been like this, she guessed, perhaps...... Is the space still upgraded, and her level is not enough?

Of course, this is just speculation, and occasionally she comes in and tries a few seeds, but it hasn't worked out yet.

In front of the second wall, she also stood for a while, the color and fabric did not appear new, and when she reached the third wall, there was about the purification and detoxification of sea salt.

Later, it could be a big deal.

She didn't plan to cover a piece of the sea, and this thing was impossible, but in the country near the sea, there was a Bai surname who relied on sea salt to survive, and they needed it.

Although those people are not from the Celestial Empire, maybe one day, they will become enemies of the Celestial Empire, but many times, the matter of fighting is not the pot of the white surname.

So, if the time is right, she will come up with this recipe.

Putting down the square, she came to the front of the fourth wall, and as she expected, it was a little clearer, but only a little.

"Really...... Merely...... If so, should I take it out? ”

She whispered, a little undecided.

Obviously, what appears in her space has never been comparable to anything else.

Since the black medicine is mentioned, the navigation is thought of, the sea trade is thought of, and the space has changed, and the fourth wall is basically inseparable from these things.

If it is a weapon, the lethality must be not small.

She wants weapons, she wants to protect herself, but in case...... To be taken away by someone with a heart and become a tool to harm others is her sin.

For a moment, she had mixed feelings, not knowing whether to expect the fourth wall to be a weapon or something else.

After staying for a while, she came out of the space, and Yan Yu had been sitting at the table, waiting for her to appear.

"What's wrong?" When she went in for a while, a lot of time had passed, Yan Yu came over, and seeing her strange expression, he couldn't help but ask.
