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

In the county military police office, Nagano Yokoo summoned Wang Daben, the commander of the puppet army, Hu Xiaowei, the captain of the detective team, and Jiang Dazhuang, the chairman of the puppet regime. Four portraits were placed before them: Mancang, Hu Zi, Wang Min, and Liang Ping.

"These two are the core members of the Mo Dao Gang, and these two are female doctors from Hui Chun Tang. You must mobilize all your forces to find them, not just in the county town, but in every town and village! Even if you have to dig three feet into the ground, you must find them!"

"Also, there's a village called Zhao Village in Xiahou Town. The people there are skilled at raising dogs and even more skilled at wielding knives. Finding their location will reveal the truth about the Mo Dao Gang! Furthermore, these two young women are very likely the ones who stole the medicine for the Mo Dao Gang, so finding the other two would be a logical next step!"

"This Mo Dao gang has caused us enough trouble. We must find their stronghold no matter what! This time, we must wipe them out!"

"Ten silver dollars for reliable information, one hundred silver dollars for finding the exact location, and one thousand silver dollars for killing any one of them! The three of you must do your utmost to accomplish this task, I beg you!"

Nagano Yokosuke, unusually, stood up and bowed to the three men, leaving the three traitors bewildered. They quickly returned the bow.

It seems this Mo Dao Regiment really hurt the Japanese, because this time they're giving these Chinese traitors, whom they usually don't care about, such important positions! They've even started offering huge rewards!

"Yes! Your subordinates will do their utmost!" the three quickly replied.

"Alright! Take these four portraits and get on with your work! I hope to hear good news from you soon!" Nagano Yokogaki dismissed them.

Inoue Masao's latest defeat made him feel extremely threatened! Unbeknownst to him, such formidable enemies had grown up around him. He dared not reliably supply the front lines with provisions unless he completely eliminated them! Another mistake and he would be left with only seppuku!

The suggestion to rely on three traitors came from a colleague in Yudu. Sometimes these traitors are more adept at dealing with the Chinese. Hopefully, it will work!

After the three traitors left, Nagano Yokosei once again took out the rocket-like arrow and the bulletproof vest that Inoue Masao had concocted. If it weren't for this failure, the invention of the bulletproof vest alone would have been enough to make his junior famous throughout the entire Japanese army, and he could have advanced even further! But all of this was drowned out by this defeat; not a single bubble could rise. Who would care about the petty tricks of a defeated general?

He had been studying that rocket for quite some time; the principle was simple, just like a skyrocket. But how to achieve the effect of firing thousands of rockets at once was a problem they couldn't figure out no matter how hard they racked their brains! The launchers captured in several battles were just a few pieces of rotten wood; there was no complete prototype to use as a reference.

……

By the time Mancang and his group of five returned to Tianma Village, the sun was high in the sky. The two female doctors examined Manxin's injuries and administered a penicillin injection. Half an hour later, his fever began to subside, much to the relief of everyone who had been on edge all night. After settling the two women in, Mancang didn't have time to spend with Zaohua and immediately went to her room to get busy.

After this battle, it wasn't just Nagano Yokosei who felt the crisis; the Japanese had concocted a simplified version of bulletproof vests, which made him feel like he had a thorn in his side. If they were to become useless in a mass attack, future battles would be much more difficult!

We must modify the rockets, otherwise once the Japanese spread bulletproof vests, we'll be finished!

Later rockets were made based on the principle of swarming. If you could extend the original gunpowder cartridge and fill it with steel balls, wouldn't it be a small bomb? Even if it didn't hit the enemy, the series of explosions would be enough to give them a hard time!

Without further ado, they made it. The paper tube, gunpowder, and arrows were all readily available; the only thing missing was steel balls. With a blacksmith around, these were no problem; they cut some iron filings the size of mung beans to use as a temporary substitute. A one-inch-long section of cardboard was partitioned off at the end of the original paper tube, filled with gunpowder, a fuse, and a few iron filings. The rear section was then filled with propellant, and a makeshift rocket was born!

The principle is simply to add a landmine (a larger firecracker) in front of a rocket; it's not difficult to make. However, figuring out how much metal filings to use to avoid affecting the range and flight attitude requires careful experimentation.

Soon, three rockets filled with different weights of iron filings were completed. They hurriedly called Tiger and went to the main road at the entrance of the village to test them.

"Whoosh whoosh whoosh! Boom boom boom boom!"

"Whoosh whoosh whoosh! Boom boom boom boom!"

"Whoosh whoosh whoosh! Boom boom boom boom!"

After three shots, the two men went forward to check the results.

"My goodness! Uncle Cang! You've concocted a flying grenade! That's incredible!" Tiger exclaimed in astonishment as he looked at the small crater that had been blasted into the road.

The first arrow exploded, leaving a crater the size of a water vat in the ground, and the flying iron filings shattered the surrounding bushes, scattering broken branches and leaves everywhere. It's a pity the range was only a little over two hundred meters, which seemed rather short!

The crater left by the second rocket explosion was the size of a washbasin. The surrounding bushes were noticeably less scattered than the first rocket, but the range was not much different from the previous rockets, so the effect was still acceptable.

The crater left by the explosion of the third rocket was only the size of a bowl, and the destructive effect was much smaller. However, its range was surprisingly much greater than that of the previous rockets, reaching 450 meters! It can be said to be a considerable unexpected gain!

"What are you guys doing? Why are you making such a commotion?" Just as the two were comparing the effects of their experiment, Da Zhao and his brothers rushed over after hearing the commotion, looking at the large crater on the ground and asking in confusion.

"Ultimate move, come quick! Look at the missile that Uncle Cang has concocted! Look at the effect, what would happen if this hit a group of Japanese soldiers?"

"Missile?..." Da Zhao asked, puzzled.

"It's a complete scramble! They just modify a rocket and turn it into a flying grenade. Look at the results! We don't even know which one to choose for the final design!" Tiger explained excitedly.

"What... what's going on?" The brothers were still puzzled.

"Oh, the Japanese made a bulletproof vest this time! So Uncle Cang modified our whole flock of vests..." Tiger recounted the whole story in detail.

"Huh?...This is amazing! Each of the three has its own advantages, and I can't bear to give up any of them!" After understanding the ultimate move, he also became conflicted.

"Why bother choosing? Let's just keep all three! When fighting the Japanese, we can just choose the right arrow based on how far away they are! Use the third one for those who are far away, the first one for those who are closer, and the second one for those who are neither too far nor too close! Dozens of missiles falling from the sky, just thinking about it is so exciting!" Manxiang suggested.
