Chapter 261: Killing Stops Killing

Immediately, she asked the soldiers on the city tower to find out, and learned that the other party's methods of attacking the city were actually very old-fashioned.

It is an ordinary ladder and a wood, covered by a bed crossbow underneath, which is completely numerical and uses human lives to travel.

And the methods of defending the city on the side of Blackwater City are also the same old-fashioned, nothing more than stones, boiling water, bows and arrows, etc., in case they climb up, they can only use guns and knives.

Moreover, there is still a shortage of bows and arrows, mainly relying on stones, and even firewood for boiling water is running out, and many places in the city are even demolishing houses and using doors, windows and beams as firewood.

There is a scarcity of supplies, and indeed, it will be difficult to sustain in a few days.

Su Fu was in a heavy mood, and now it was too late to build a trebuchet, so she could only think of other ways, and she remembered the formula of gunpowder very well.

But she has been hesitating whether to make the gunpowder formula public in advance, which is a big killer, directly past the era of cold weapons, and enter a more tragic war level.

And even if she took out the recipe now, it would be impossible for Blackwater City to have so much sulfur and saltpeter, and saying it was tantamount to not saying it.

returned to the post house and discussed it with Luo Tianjiao, and she was not optimistic about the prospects of Blackwater City.

"Even if you let General Hu leave immediately, you may not be able to rush to the rescue."

"According to you, there is nothing you can do?"

Although Su Fu had many ideas in her mind, she couldn't decide how to start, and wanted to learn more about traditional offensive and defensive methods.

"Not at all, unless there is a miracle, such as a divine soldier descending from the sky, and the other side suddenly withdraws its own troops or something."

Luo Tianjiao was amusing herself and made a joke.

Su Fu smiled when she heard this, anyway, she could hold on for a few days, so let's take a look at it more.

Early the next morning, when she got up, she found that Luo Tianjiao was long gone, and after asking, she found out that in the early hours of the morning, the Wei army launched another large-scale attack.

Seeing the tragic situation of the battle, Luo Tianjiao, as a soldier, naturally couldn't sit still, and took the initiative to ask Ying to run to the city tower to help, but he didn't come down until now.

There was a new group of wounded soldiers in the city, wailing and blood everywhere, and many women were busy cooking breakfast and some were helping to bandage their wounds.

Sov walked around the room, and although she didn't face the scene of the two sides fighting, she had a further perspective on the war.

Immersive, the shock of this is not comparable to hearsay.

After a circle, Su Fu suddenly raised a question, this city is called Blackwater City, but where is the water?

It can't be the moat outside, it's too much to say.

I casually asked a local old man, and then I learned that the so-called black water is because the underground river under the black mountain outside the city is black and cannot be drunk at all.

Black underground river? Su Fu's heart moved, could it be the kind of thing she had in mind?

"Are there any characteristics of these black waters? Isn't it a bit like oil, especially flammable? ”

The old man's eyes widened in surprise, "How do you know, it's true." A little spark is easy to burn and lasts for a long time. ”

"It is rumored that many years ago, because of the fire in the Blackwater River, our Blackwater City was burned down. So for generations to come, we have a stern warning here, don't let the black water burn easily, or it will bring disaster. ”

Su Fu was very excited when she heard this, this so-called black water is likely to be oil, and it is indeed very surprising to find a natural oil deposit here.

If everything is true, it will not only solve the current dilemma, but also play a vital role in the development of the beam in the future.

At this time, there was still a war in the city, and Wu Rang definitely didn't have time to pay attention to himself, so Su Fu immediately made a decision and found an old post man who was familiar with the local situation in the post house and showed them the way.

Blackwater City was originally built on the mountain, and after leaving the city, it walked along the mountain road to the left, all the way over the mountains and mountains, until it was deep in the mountains, and then stopped.

"I remember that there is a black water hole in this valley, and you can directly see the underground river inside, but because it has been abandoned for many years, I am afraid it is very difficult to walk."

Su Fu took out some fluorescent stones, "Let's use this for lighting, don't start a fire, I have read a record of this kind of black water in an ancient book before, it can volatilize into the air and cause a fire." ”

Everyone listened to this, and they were all cautious, but fortunately, although these fluorescent stones were not particularly bright, they were still able to barely walk in the dark hole.

As soon as she entered the cave, Sov smelled a familiar smell in the air, a sensation similar to raw gasoline.

couldn't help but perk up, it seems that she didn't find the wrong place, the black water here is 100% oil.

According to the old guard's instructions, they stopped after walking about 200 meters in the cave.

"There's a waterhole in front of it, and there's black water in it all year round."

Following the direction of the old postman, they soon found the black pool.

Looking at the jar of black water in front of her, Su Fu was very excited

, reaching out to scoop up a little and take a closer look.

Frightened, the old post guard hurriedly stopped, "This can't be moved, it's poisonous, there have been people who vomited and diarrhea after eating it by mistake, and almost died." ”

Su Fu smiled, "I don't drink, I just take a look, it's okay." ”

It's strange to drink oil into your stomach without vomiting or diarrhea.

However, after his reminder, Su Fu did not continue to scoop directly with her hands, but took a leather bag filled with water and filled half a pot.

The task was completed, and Sufu didn't linger any longer, "Let's go, let's go back first." ”

The old postman was surprised, this is the end? asked curiously, "Miss Su, what are you doing with all this black water?" Is it to make medicine? ”

It's no surprise that he had this idea. Traditional Chinese medicine says that medicine is three parts poisonous, and the more toxic things in turn, can basically be used as medicine, so he has such an idea.

There are so many things that can be done with oil, including medicinal herbs, although the current technology is not yet available.

But as long as there are basic raw materials, one day these things will be realized.

"Yes, it can make medicine."

Su Fu is very confident that with this baby, this war will definitely be won, but ...... I'm afraid a lot of people will die because of her.

But this is war, and only by killing can we stop more innocent people from getting involved.

"Old man, is there any other place around here where you can harvest black water?"

After thinking about it, the old man said with some uncertainty: "I heard the old man say that when the Blackwater City was built, the black water was dug out and later buried in the ground. ”

Is there in the city?

Su Fu was overjoyed, that was great, it seems that God helped me, Blackwater City was completely saved.

Eagerly asked, "Do you know where you are in the city?" ”

The old postman shook his head, "I don't know, it's too old, who can remember it." ”
