Although Shang Qiu swore that she would have a way to sneak into the outermost layers of the dungeon, Chu Nan was still not at ease, he never fought unprepared, and Xianyang's dungeon imprisoned so many terrifying people in the Six Kingdoms, after all, his life can only be reassured if he is in his own hands.

He picked up a branch at random and wrote on the ground, except for him, no one could know what he wrote on the ground, he used not Qin script nor any kind of script in the Six Kingdoms but simplified Chinese characters of later generations, he wrote saltpeter, sulfur, charcoal, no one knew what these three things were related, but Chu Nan knew what these three things could become if they were mixed together in a certain proportion, that was gunpowder, and if he could make them, it would definitely greatly improve their survival rate.

But it was obvious that he couldn't do it alone, he had to have helpers.

After Chu Nan explained to Tianming for a long time, Jing Tianming looked at him with a strange look and said seriously: "Brother Chu, are you sick?" ”

"I'm not sick!"

"Then why are you buying medicine?"

"Medicine... What medicine? Chu Nan was puzzled.

Tianming said: "I know the charcoal you said, but saltpeter, sulfur, it sounds like the medicinal herbs used in the medicine shop, stone flow yellow and the like." ”

"You said that these are all medicinal herbs, can you buy them at the pharmacy?"

"Of course!" Tianming replied, looking at Chu Nan and thinking that it seemed that he was really sick, and he was not lightly ill.

Looking at Tianming looking at him like an idiot, Chu Nan didn't know what he was thinking, and pulled down his face, "This is some money, you go to the pharmacy and buy some saltpeter and sulfur." ”

Tianming took the money and said in a low voice: "I also said that I am not sick, and I have to buy medicine." ”

Chu Nan pretended to kick him, "Don't go yet!" ”

Tianming ran away and turned his head and asked, "How much." ”

"The more the merrier!"

At night, the shadow guards live

Zhang Han looked at Chu Nan in front of him in a military uniform and frowned. "Why are you here, I don't know your identity is secret, it's not good if you let others know your identity."

"Don't worry! I went around in a big circle in Xianyang City, and even if someone was following me, I would have been thrown away a long time ago. ”

"Say it! What's up? ”

Chu Nan smiled, "I came here this time to ask the general to borrow something." ”

"Borrow something, no." Zhang Han replied simply and rudely.

Chu Nan didn't speak anymore, turned around and went out and said leisurely: "Since the general has no intention of helping his subordinates, if there are any three strengths and two weaknesses on the way to the mission, it will be difficult for the general!" ”

"You wait!"

Listening to Zhang Han's words, Chu Nan stopped his steps, he has been in the army for a long time Chu Nan of course understands the thoughts of these chiefs, as long as he grasps the lifeblood of these chiefs, plus his words are more clever, as long as it is not excessive, he will generally agree, but if he meets a ruthless general, then he can only ask for more blessings.

"I knew the general wouldn't let me die like this."

Although Zhang Han is sympathetic to his subordinates, he does not include Chu Nan, what he is worried about is the life of his old friend's daughter Shang Qiu, if Chu Nan knows the truth of the matter, he is afraid that he will want to cry without tears. ”

"Say it! What do you want. ”

"Charcoal!"

Zhang Han was puzzled, "What do you want charcoal for?" ”

"It's inconvenient to talk about this humble position with the general."

If his subordinates usually talked to him like this, he would have been dealt with by his own military law a long time ago, but Zhang Han was appreciative of Chu Nan and was not angry. ”

"If it's charcoal, there's a lot of charcoal in the army's iron-making department, and I'm afraid people will ask about it."

"Don't want charcoal in the army!"

Chu Nan refused, whether it was in the army or in the people, charcoal often contained a lot of impurities, and it was not easy to mix the dose, it was very dangerous, of course he could not use it as a material for gunpowder.

"Don't want charcoal in the army, then where do you need charcoal!"

"I heard that the Yin and Yang family ......"

"You're bold!"

"The charcoal required by the Yin and Yang family is all carefully selected by craftsmen because of the extremely high temperature required, and it is used for His Majesty's alchemy, how can it be wasted on you."

There was silence in the room.

"It's a bit difficult, but I think the general will be able to get it."

Zhang Han looked at him and smiled, "I can indeed get it, but you have to promise me one thing." ”

"What's the matter?"

"Help me take care of Shang Qiu."

"Definitely!"

The charcoal that Zhang Han promised came quickly, and a special person sent it the next day, looking at the charcoal in front of him that was so pure that it was a few o'clock, Chu Nan raised a trace of an obvious smile at the corner of his mouth, and then muttered with some dissatisfaction: "It's a pity that there is only so little, it's really stingy." ”

Tianming looked at the charcoal in front of him, "What's the use of these." ”

"You'll know then!" Chu Nan smiled mysteriously.

In a dense forest on the outskirts of Xianyang City, there was an occasional roar, accompanied by someone's scream and bursts of birds.

Naturally, it was Chu Nan and Jing Tianming who made such a sound, but at this time, the appearance of the two of them was extremely miserable now, the cloth robes on their bodies were already in tatters, and because of the saltpeter, their faces were full of thick black ash and they couldn't distinguish their original appearances.

Chu Nan and Tianming found a stone at random to sit on, because they were too tired and they almost collapsed on it.

"Failed again?"

Chu Nan sighed and said in disappointment.

Tianming's face was now full of darkness, and he could still see his original appearance except for a pair of eyes that were still bright, "No, you must treat me to a big meal when I go back." ”

Chu Nan nodded angrily.

He didn't have a special weighing tool, but he relied on his own naked eye observation and his own feeling to mix saltpeter, sulfur, charcoal and other things, the effect was naturally unsatisfactory, and saltpeter and sulfur were okay to say that Chu Nan was even more helpless when he saw only a small bag of charcoal left, if he ran out like this, he thought that if he went back to ask the general for charcoal, he could almost feel the general's anger.

Fortunately, the gunpowder that Chu Nan is configuring now is not very powerful, otherwise with his method, where would he still be able to stand here.

On the other hand, Tianming next to him could be said to have an excited look, and he patted Chu Nandao: "This is much stronger than the fire meteor set in Xianyang City during the festival." ”

Seeing Tianming stretching out his hand to learn Chu Nan's movements to make gunpowder again, he hurriedly stopped, "You don't want to die!" ”

Tianming hurriedly put it down at this time.

Looking at the darkening sky and the plans that are getting closer and closer, it seems that this is the only way to go.

He took out the cloth he had prepared from his body, and made about four packets of gunpowder from the remaining charcoal, according to the configuration of the most powerful time.
