I used the Mo Dao (a type of long-handled sword) to fight the Japanese.

"Haha! Good girl! Where did you buy that balloon that's flying now?" Mancang asked with a smile, just like the Big Bad Wolf coaxing Little Red Riding Hood!

"Over there! The balloons that grandpa bought can fly! Do you want to buy one too?" the little boy said innocently.

"Haha, great! Brother, go buy a few for sister too, sister wants to fly too!" Mancang said, winking at Zaohua beside him.

"..." Zao Hua rolled her eyes. What kind of time is this to still treat people like children? How irresponsible!

"Thank you! You can find them just one turn east at the crossroads. They come in all sorts of colors!" the woman said as she stepped forward to express her gratitude.

"Okay! Thank you!" Mancang replied politely.

After saying goodbye to the mother and daughter, Mancang couldn't contain his excitement. He thought that hydrogen balloons only existed in later generations, but he never expected to see such a wonderful thing in this inconspicuous town!

Don't underestimate these little hydrogen balloons; they're crucial for taking down the Japanese airfield!

"What are you thinking about? Why are you laughing so filthyly!" Zao Hua said irritably, looking at the big boy next to her who was laughing happily.

"Haha, do you think a grenade tied to the bottom of a balloon can fly into a chicken coop?" Mancang said mysteriously.

"Huh?...What do you mean? You want to use these balloons to blow up...a ​​chicken coop?" Zaohua asked, her eyes wide. She meant to say blow up the airport, but the words stuck in her throat and she changed them to "chicken coop."

"Can you just say it's okay?"

"Sure! Of course!" the little girl said, her eyes lighting up.

"Let's go find that old man! Buy all his balloons and equipment!"

Soon, the two returned to the inn, pushing a large bunch of balloons and two strange earthenware jars. Without even eating, they closed the door and began tinkering. The young girl, true to her university education, quickly calculated that at least four helium balloons tied together were needed to suspend a grenade. She also meticulously calculated the wind direction, flight speed, and the required fuse length!

Mancang, standing to the side, was completely stunned! After half a year, she was no mere pretty face; her data deduction alone was something even this college student from the future couldn't match! This little girl is quite capable!

"Alright! Now that everything's cleared up, there's a practical problem that urgently needs to be solved. Where are we going to get those wooden-handled grenades you mentioned? We only have the Japanese sweet potato grenades!" Zaohua asked.

A grenade suspended from a balloon requires a wooden handle; a sweet potato grenade needs to be tapped to trigger. Hanging it from a balloon is practically useless! Who knows if it will explode if it falls!

A single wooden-handled grenade has too little explosive power; it's best to hang two together. The wooden-handled grenade controls the descent time, while the sweet potato grenade amplifies the effect; the combination of the two is most effective!

"We don't have guns or cannons, but the enemy makes them for us! We don't have them, but those puppet troops definitely have plenty. Let's call a few of us over and get them!" Mancang said nonchalantly.

The fact that the puppet troops have them is the same as not having them. There's no need to be polite with these bastards.

"Hehe, look how capable you are!" Zao Hua laughed as she looked at Man Cang, who was beaming with pride. With a solution in hand, the little girl regained her usual liveliness.

"Let's get them up and start working! Let's make sure we're ready tonight so we can invite the Japanese to celebrate the Mid-Autumn Festival early tomorrow morning," Mancang said confidently.

"Look at you, so capable! You guys go ahead, I'm going to sleep! I'm exhausted every day!" Zao Hua yawned and went straight to Man Cang's bed, collapsing into bed and falling asleep without caring at all that Man Cang had slept there!

When the remaining four learned of Mancang's idea, they immediately perked up and praised the method of suspending grenades with balloons!

"Amazing! Amazing! They say that men and women working together makes the work easier, and you two came up with such a brilliant idea while just strolling around town. You truly are a match made in heaven!" Qingquan praised.

“That’s right! I think you should get the wedding done as soon as winter comes! You’ve been busy all year, this is a good opportunity to celebrate!” Qingshui added.

“That’s a good idea! I don’t think her brother would object!” Sun Zhengyi said.

“Brother, I think it’s a good idea! The villagers are living in constant fear during this time of war, so this is a good opportunity to have some fun!” Man Gui chimed in.

"Stop, stop, stop! We're talking about fighting the Japanese, where did you get to? Hurry up and grab some Japanese clothes so we can go get some grenades!" Mancang urged as the group got more and more carried away with their conversation.

"Hahaha, sorry, Brother Mancang!"

"Let's go, let's get some grenades!"

With that idea in mind, everyone chuckled and went out to find those scoundrels to get some grenades.

Being unfamiliar with the area, their first priority was to find out the location of the puppet army's camp. The brothers spread out on the streets and quietly followed the puppet army members who were wandering around. Half an hour later, the five of them met again near a large courtyard on the north side of the town, as expected.

"It seems this is the Japanese stronghold. I wonder if there are any Japanese soldiers inside," Qingquan said.

“There should be. All the strongholds in our county have Japanese soldiers,” Shimizu added.

"Let's take it first, whether we have it or not! We've fought the Japanese so many times, taking down a stronghold is a piece of cake!" Man Gui rubbed his hands excitedly. Now, instead of being afraid of the Japanese, he was actually quite excited!

"Keep a low profile! Keep a low profile! Don't let a small outpost delay important matters! Let's go, drive there!" Man Cang quickly reminded everyone as they rubbed their hands together in anticipation.

"Yes, yes, we can't delay important matters! Let's go!"

Soon, the group quietly returned to the street. A short while later, a Japanese military vehicle drove up and headed straight for the courtyard, where it was stopped by the puppet troops standing guard at the gate.

"Baka! Get out of the way! Anyone who delays the Imperial Army's important business will die!" Man Cang shouted, sticking his head out.

"Hey! Sir, please come in! Please come in!" The puppet troops, seeing that the Japanese were not to be trifled with, quickly nodded and bowed to make way.

"Where is your captain? Tell him to come see me right now!" Man Cang continued to ask sternly.

"The captain just went out, I'll call him back right now!" Er Gouzi said, about to leave.

"No need! Take me to the gunpowder warehouse. The Imperial Army needs a batch of wooden-handled grenades for experiments, hurry up!" Mancang continued to put on airs.

"Hey! Hey! This way please!" Er Gouzi gestured for the car to turn left, personally leading the way with excessive attentiveness.

The vehicle soon stopped in front of a house. The door was locked, and there wasn't even a guard around.

"Open the door!" Mancang ordered as he got out of the car.

"I...I don't have the key...I'll go get someone to open the door right now," Er Gouzi said awkwardly.

"Go! Hurry up!" Mancang turned around and, seeing no one around, urged sharply.

"Crack!"

Just as Er Gouzi turned around to leave, a step forward was taken, Er Gouzi's head was grabbed from behind and twisted, and Er Gouzi was dealt with in a clean and efficient manner!
