When developing military industry, gunpowder is king. Because gunpowder is the most indispensable component of all weapons.

Whether it's a gun or an artillery shell, whether it's a grenade or a rocket, whether it's a mine or a torpedo, whether it's a missile or an aerial bomb, if it doesn't contain gunpowder, it's all doomed.

Of course, gunpowder is just a general term for all filling powders, and can also be subdivided into various types of explosives, propellants, etc.

Based on the material and financial resources currently at his disposal, Hu Changyi thought it was better to get black powder first! After all, the source of materials for this thing is the easiest and the preparation is simpler. Apart from being less powerful, there is nothing else.

The power is small, so won’t it increase the amount of powder? If 40 grams of black powder is put in a mine, it won’t kill the Japanese, but what about 4,000 grams? It can always kill them, right?

In fact, Hu Changyi himself knows the formula of black gunpowder, and even many people around him know the formula. However, Hu Changyi still "buys" it from the system. Because black gunpowder is packaged with the production of soil salt, charcoal production, etc.

Wait for basic things.

When looking at the system, Hu Changyi did not look carefully. It seems that there are some practical formulas in the black powder exchange list. For example, formulas with smaller explosive power but stronger propulsion capabilities are very practical, right?

?

Also, with black powder, other things can be made one after another, such as the elm cannon. The elm cannon is so simple that Hu Changyi doesn’t even need a system. He only needs an old elm wood and two carpenters.

Just add some wire and iron bars.

The elm cannon is a sharp weapon for ambush, and it is suitable for the large combat environment we are in now. It is also the first military product that Hu Changyi thought of.

"System, spend 20 merit points to exchange for black powder and all the technical information attached to it!" While walking on the road, Hu Changyi redeemed the first product from the system.

"Ding...the host successfully redeemed the technical information of black powder and all its ancillary products!"

"Ding, the system reminds the host that the black powder produced by the system is of reliable quality and at a favorable price. The host only needs to spend a little merit point to exchange for 500 kilograms of black powder. For details, please see the second to last line on the third page of the material classification in the system mall.

(Note: Black powder is a raw material for military technology, and the host can exchange it for finished products)."

"I...fuck you! Are you trying to trick me? If you had told me earlier, it would have wasted my 20 merit points." Hu Changyi cursed in his heart.

System subtitle: "Host, please read the system mall redemption page carefully to avoid missing products."

Hu Changyi: "...(*￣︿￣)..."

However, Hu Changyi's helpless and speechless mood only lasted for three seconds and ended. The reason is that, as mentioned before, black powder is indispensable for the development of military industry. At least according to the current conditions, this technology is really necessary

Information will do.

Because only by leading people to create black powder, or even a small workshop, can we make any military products in the future. It can also provide cover for the products produced by the system.

People are not stupid, and this is not a time-traveling system novel. People around the protagonist ignore the various abilities of the protagonist, and even ignore the various advanced weapons that the protagonist brings out from time to time. Water has a source, trees have roots, everything

All actions are traceable. As long as you investigate carefully, some things are difficult to hide.

However, there are no traces of the technology that exists in the brain, so you can use it as much as you like. As for how the technology came about? The original owner has been in a daze for these years, and it will be okay after he has figured it out? Anyway, he can make guns because of his family's skills.

Isn’t it difficult to understand? Once more guns are manufactured, it will be okay to be able to design guns, right?

Well, that's what Hu Changyi thinks. Work hard in military industry, work hard to strengthen the team, and work hard to kill the Japanese. When the system is upgraded to a high level and you have accumulated enough merits, you can return to the original world and continue living.

As for whether souls from this world will travel back to do entertainment, that's not his business...

"Uncle Fengnian, what day is it today?" Hu Changyi walked up to Zhao Fengnian and asked.

"Today is...the fifth day of September!" Zhao Fengnian thought for a while and said.

"Where's the Gregorian calendar?" Hu Changyi asked.

"In the Gregorian calendar... October... the 8th, right?" Zhao Fengnian said uncertainly.

"It's the 9th, yesterday it was the 6th!" said Xing Dezheng, who was being carried on a stretcher.

"It's the 9th? I remember it was the 3rd?" Hu Changyi was surprised. Because based on his body's memory, today was the 3rd.

"Hey... this silly kid... Diao Qixian knocked you out with a stick. You were knocked unconscious for five days, and you were almost out of breath. Fortunately, Dr. Sun in the team knew how to treat illnesses, so he saved you! For

To save you, half of Dr. Sun’s ancestral wild ginseng has been used!”

"You didn't wake up until midnight yesterday, but you didn't know anything about it, and fell asleep again... Come on, stop talking, if we hadn't taken care of you, we would have entered the Jizhong Plain by now." Zhao Fengnian said.

"Is it possible that this soul travel still needs time? Or maybe I came here after the original owner died?" Hu Changyi thought for a while and asked: "Where are we now? How did Captain Li find us?"

"We are now near Pingshan County. The Japs have been unable to open up the situation at Xinkou, so they are preparing to fight from the east to the west. At this moment, troops are being mobilized to prepare to attack Shijiazhuang! We are also unlucky, and were

The Japanese's Xiaogu troops were discovered, and they reached our base in the middle of the night!"

"As for Commander Li, he was preparing to help the Second War Zone guard Niangziguan. He just happened to wipe out a group of bandits. Only then did he find out that the bandits attacked your team that sent guns a few days ago. Only then did the scouts follow the clues and find them.

Our station just happened to catch up with us being chased by the Japanese." Zhao Fengnian said.

"Okay..." After hearing this, Hu Changyi finally knew his exact location, and also remembered what big things would happen in the future.

The biggest event was naturally the fall of Taiyuan on November 8, the fall of Shanghai on November 12, and then the fall of Nanjing a month later, followed by a massacre that shocked China and the world. 300,000 compatriots were all turned into dead souls under the butcher knife of the Japanese invaders.

And it’s the kind that hasn’t been publicly sacrificed for decades...

During this period, due to troop strength and other reasons, the Eighth Route Army could only play side projects around the main battlefield, carry out ambushes, attack the Japanese supply lines, and support the main battlefield from the side.

Well, these Eighth Route Army ambush battles and guerrilla warfare are very good. If the main battlefield can seize the opportunity, there is a great chance to reverse the situation.

For example, behind the battlefield of the Battle of Xinkou, the Eighth Route Army attacked Yangmingbao Airport at night, ambushed Yanmen Pass, and bombed the Tongpu Railway. Pingxing Pass was captured again, completely cutting off Seishiro Itagaki's logistics line.
