Wang Sanlang walked back to the cave quickly, took out the backpack that Ye Yun handed her at that time from the hidden corner of the cave, and opened a hidden small mezzanine at the bottom of the backpack, as if he had returned to the day of the trip to Peach Blossom Village, when he was just about to walk out of the door, but he didn't want his daughter-in-law to hold him and say a word in his ear. 'Saburo, if one day you reach a dangerous situation where the mountains and rivers are exhausted, open the hidden compartment at the bottom of the backpack, and maybe it can save your life. Wang Sanlang can still think of his daughter-in-law's serious expression when he closes his eyes now, so even if he is curious, he has not opened it once, but this time he is really exhausted, if he can't save himself, and if he drags on for three days, everyone will really not be able to go home.

?‘ Saburo, when you read this letter, it proves that you are really in danger, otherwise you may never have the chance to see this thing born. This is the way to save you, gunpowder, I know you haven't heard of it, but it is undeniable that it is a weapon of murder, and when it explodes, it is so cruel that I really don't want it to happen.

Okay, don't talk nonsense, remember one time playing in the mountains, I pointed out to you the saltpeter? I have learned about that thing, it is found in the mountains in most parts of the country, so you have to find it, add sulfur and charcoal, according to the ratio of fifteen kilograms of firepeter, two kilograms of sulfur, three kilograms of charcoal, and so on, and then seal it with something like a bamboo tube, remember to seal it with a hay rope to leave a lead, and light it with fire, remember, you must stay away before the straw rope burns out.

I hope this thing can help you, we are waiting for you to come home and love your wife, Ye Yun. ’

Wang Saburo wiped away the tears that he didn't know when, put the letter back untouched, and hid his backpack back. He got up and walked out with a firm step, but his mood was not at a loss, because someone was still waiting for him to come home.

?“ San Lang, are you out? I've already called for it, and now it's reorganized, there are a total of eleven squads, and these are the newly elected squad leaders. Shanzi looked at Wang Saburo who walked out of the cave, and hurriedly reported, you know, the time is very tight now, it can't be wasted, and even people like Shanzi who love to joke are not in the mood.

?“ Report on the personnel. ”

?“ Yes, there were 260 people at the time of departure, 149 dead, 111 people now, 23 slightly injured and 2 seriously injured. Shanzi reported the latest casualties to Wang Sanlang. In fact, if it weren't for Wang Sanlang having the medicine prepared by Ye Yun at that time, the casualties might have been even worse. It's a pity that Rao is like this, and there is not much medicine left in Saburo's hand.

?“ Okay, now everyone listen to my command, don't ask why, the military order is like a mountain. We only have three days, and success or failure is here, understand?" Wang Sanlang was afraid that everyone would ask about gunpowder, so it was better not to say anything at all than to make everyone suspicious.

?“ Yes, subordinates obey orders. In fact, what Wang Saburo didn't know was that even if he didn't say it, everyone wouldn't ask more, and everyone had a blind worship of him, so even if they knew that they were already in deep trouble, there was never a situation where the military was discouraged.

?“ Obey the order, the first team goes to the bamboo forest in the east, we need bamboo tubes, the better the moon thickness, the more the better. The second and third squads, find this stone in my hand and grind it into powder, the more the better. After Wang Sanlang finished speaking, he handed over the saltpeter that he had just picked up by the cave, Ye Yun was right, there are many such stones in this place.

?“ Yes, the subordinates received the order. ”

?“ The fourth team went to collect sulfur in a cave not far from the valley where we had just entered, and if I am not mistaken, there was a natural hot spring. The fifth, sixth, and seventh squads prepared sharp wooden spears and bows and arrows. The eight, nine teams will follow me in a while, I have other arrangements, the 10 teams are responsible for guarding, Shanzi, you also join them, responsible for leading the team. Team 11 was responsible for burning charcoal, preparing everyone's meals, and taking care of the two seriously wounded. We don't have much time, so I'll just give you a day and a half to prepare, and I'll arrange the rest. ”

?“ Yes, captain, subordinates receive orders and ensure the completion of the task. ”

?“ Okay, let's start preparing now, and Team 89 will follow me. ”

?“ "Although everyone is confused about Wang Saburo's seemingly clueless tasks, it does not hinder everyone's speed of action, although this battle seems to have no chance of winning, but what if the blind cat runs into a dead mouse, right?"
