The sound of the wolf howling gradually turned into a subtle whimpering sound. In order to determine its specific location, Haneda shouted towards the pitch black: "Head Wolf, where are you?" The Head Wolf was extremely smart and immediately echoed, fully understanding Haneda's intention. Haneda closed his eyes and listened to the voice attentively. He could conclude that the alpha wolf was at his feet.

He Chujiang led the way, and Haneda quietly opened his clairvoyance eyes and looked at the abyss not far from his feet. He didn't know it, but he was shocked at the sight.

Oh my god, it turns out that this is not a bottomless abyss, but a large place where saltpeter is boiled! Unlike the three pots seen outside, there are no pots for boiling saltwater here, but deep pits. Those pits are so deep that you can't see the bottom, but each pit is a full ten meters wide. It's really scary!

It’s hard to imagine how there could be such a large salt-burning site deep in this desolate and dangerous place, and how it was dug out! The edges of these deep pits show a deep dark yellow color, as if they were traces left by the years. People can tell at a glance that these are the marks left after countless times of boiling salt. Next to the deep pit, you can still see some excavated earth and rocks, which are obviously the remains left when the pit was dug.

Haneda stared blankly, his heart beating wildly. He stopped. Yu Zhe and He Chujiang both sensed something was wrong with Haneda and looked in her direction. They saw nothing except a dark patch. No, how could the light from their overhead lights be seen so far away? At this time, Haneda said: "You should pay attention and look down!"

After saying that, Haneda closed his eyes tightly and paused for a moment, then suddenly opened his eyes again. The light of lightning flashed across the darkness quickly, accompanied by a gentle thunder. In the flash, the three of them saw what they thought they were just now. In the deep pit of the abyss, there are small enclosed pits lined up side by side. Next to the pit is a pot, and surrounding the pot are rows of earth walls similar to the ones they just saw.

It looks like this is a replica of the small square outside.

After the lightning, the cave fell into darkness again...

The three of them were silent, and Yu Zhe asked: "That pot is for shit, what is the earthen wall for?"

I don't know why, but he just knows Haneda's reasons. Although He Chujiang understands a little bit, he is only a general, a prince but not a professional. In this regard, she also feels that Haneda should be more professional, so He Chujiang doesn't hide it. , just waiting for Haneda to reveal the answer.

Haneda, who is usually very strict about professional knowledge, seemed a little speechless at this time: "How can you be so sure that I will definitely know?"

"I don't know whether you really don't understand or you are pretending not to know. Saltpeter has been boiled in the Qiang Kingdom. However, you know nothing about the function of this substance or only have a partial understanding." "At this time, she cast her eyes at He Chujiang, obviously meaning something. However, He Chujiang didn't take this seriously. He shrugged, showing a calm acceptance of Haneda's contemptuous attitude. He knows the scope of his knowledge and is quite humble about the things he doesn’t know!

Haneda patiently explained the science: "Build the soil into a low earth wall one foot wide and one foot long, dilute human feces and urine with water, and pour it on the top of the wall. Over time, the water from feces and urine will seep into the wall. In the body, nitrate and alkali will be generated in the earth wall, and these nitrate and alkali can be refined into earth nitrate by scraping them off." At this point, Haneda stopped, closed his eyes again, used enough strength to open his eyes, and opened his eyes again. In the lightning, she pointed to the two of them and said: "You see those earthen walls, there will be scratch marks on them. After these earthen walls are used to a certain extent, they can be completely dismantled and leached with water to extract the nitrate salt, and then they can be rebuilt again." Build a new earth wall, and the cycle repeats!”

"Don't underestimate boiling saltpeter. Saltpeter is the soul of gunpowder, and its role cannot be ignored!"

As Haneda finished explaining, the three fell into silence again, while the pit continued to remain pitch black.

Yu Zhe suddenly said: "I seem to have heard from my father that the Qiang Kingdom is thinking about powerful weapons, and they seem to have used them on the battlefield. I wonder if the fourth prince has ever experienced the power of that weapon!"

He Chujiang sighed and said: "Do you know when was the only time I was defeated in a battle? It was in the battle with Hu Jiong. He used a mysterious weapon to burn my food and grass. However, it is shocking What is puzzling is that a weapon with such a lethal power was used just once, and after it only worked for a short period of time, it disappeared without a trace and never appeared on the battlefield again."

Haneda asked: "So, after burning your food and grass, that weapon was never used again?" At this time, not only Haneda, but also Yu Zhe also showed a confused look. In fact, He Chujiang was also puzzled by this. He pondered for a long time, but still could not find the answer.

The howling sounds of wolves came out in the distance one after another. The alpha wolf became more and more anxious. Haneda became even more worried. She said to He Chujiang: "Fourth brother, let's go down and take a look. I suspect that the weapon has not disappeared, but is gone!"

"Is there any difference between disappearing and disappearing?" He Chujiang and Yu Zhe were both puzzled. However, considering that Haneda was not just talking nonsense, they might as well go down and take a look at the place where the salt was boiled, and maybe they could find the answer!

The three of them continued walking along the original route, and sure enough, a mysterious arched wooden frame appeared not far ahead. Haneda looked at the wooden frame and said to himself: "What is this wooden frame used for?"

Yu Zhe carefully observed the front of the wooden frame and saw only the area illuminated by the overhead light. All other directions were dark and he could not see anything.

He Chujiang pondered for a long time, and Haneda kept looking at him. He raised his head and found Haneda staring at him blankly, so he smiled and asked, "Why are you looking at me stupidly?"

"You are so stupid. I was just thinking about what you are thinking now, how should we go, and how did the alpha wolf run over!" Haneda also felt strange. He has always been an independent person, but just now he was on the road ahead. When you were confused, why did you subconsciously wait for He Chujiang to make up his mind? Is it dependence? If so, there is a risk and it needs to be corrected.

When He Chujiang heard her words, he nodded expressionlessly, but the corners of his mouth secretly raised, and he was secretly happy in his heart.

This is very good. She used to have her own way when things happened, but now she knows how to ask his opinion. Does this mean that this girl's mentality has slowly begun to tolerate him? He walked to the wooden shelf and lowered his head to direct the brightness of the ceiling light in this direction. Sure enough, there was a step leading to the bottom next to the shelf. Yu Zhe also followed He Chujiang's method of directing the light to the path and couldn't help but curiously asked. : "How do you know there can be a path there?"
