All the generals in the main tent were utterly astonished when they heard what Song Anxin said.

A general guarding the front line said, "Hui, Lady Hui, what you're saying about gunpowder is truly unbelievable. I know you're capable, but you shouldn't treat matters of the battlefield lightly."

“We’ll know once we make it,” General Lu said, his face full of resentment. “Damn it, if this gunpowder can really kill a dozen Hun bastards in one blow, I will make the Huns pay for the blood debts of our soldiers who have died over the years.”

Meanwhile, Yan Shuping's eyes lit up. He stepped forward and said, "General, if this gunpowder is successfully made, it will be a great help to our war in the northern frontier. Please allow Lady Hui to stay and develop this gunpowder so that we can force the Xiongnu to retreat as soon as possible and ensure the peace of our border."

“General, since my mother mentioned gunpowder, it must exist. She would never joke about the battlefield. Please believe my mother.”

Lin Fenghe trusted his mother completely.

General Yan's face was solemn, but his eyes shone brightly. He had long heard Shuping speak of Lady Hui's many ingenious ideas, and this might just be an opportunity for the Northern Frontier. He spoke:

"Good! Lady Hui, if you can really develop such a miraculous weapon as gunpowder and turn the tide of the war in the Northern Frontier, you will be a great hero of our Northern Frontier!"

Song Anxin stayed in the northern frontier, and of course, she also sent a message back to her family.

"Bang!...."

An explosion rang out on the outskirts of a small border town in northern Xinjiang, sending dirt flying everywhere.

"Aunt Anxin, it's blown up! It's blown up! We succeeded!"

Yan Ping'er jumped out from behind a protective slope, looking excited.

"Although it exploded, it wasn't powerful enough to kill the Hun cavalry. Besides, we only had a few gunpowders that exploded, so it's still not enough."

Lin Fenghe emerged from behind the protective slope and analyzed the situation rationally.

Song Anxin nodded. The power was indeed not enough. The formula for gunpowder was one part sulfur, two parts saltpeter, and three parts charcoal, which was not difficult. What was difficult was the formula ratio and the manufacturing method.

She has been working with Feng He, Ping'er, and others to develop gunpowder these past few days, but the stability and power of the gunpowder they have developed are not yet quite sufficient.

However, this time there was some progress; it managed to blast up a patch of dirt.

She said, "We'll adjust the ratio of the gunpowder when we get back. As for the gunpowder misfire issue, I'll think about it when I get back."

Back in a small courtyard in the border town, Lin Fenghe, Yan Ping'er, Qingfeng, and Qingyun continued to mix gunpowder.

Song Anxin didn't rush to join them. Instead, she was examining a package of explosives that hadn't detonated. The sulfur, charcoal, and saltpeter inside the package were somewhat separated, which explained why it hadn't exploded. It would be great if they could be fully integrated together.

She tried hard to recall the knowledge in her head, but unfortunately she was really bad at science. Suddenly, Song Anxin had a flash of inspiration. She remembered that when she was in school, there was a science boy who was pursuing her and insisted on telling her about gunpowder particle technology in order to have a conversation with her.

It seems that there are gaps between the granulated gunpowder particles, which facilitates the spread of the flame, allowing it to burn quickly and explode with tremendous power. It also reduces stratification during transportation and prevents moisture absorption, thus avoiding misfires and significantly improving the stability of the gunpowder detonation.

Upon realizing this, Song Anxin immediately stood up.

"Qingfeng and Qingyun, go fetch some water, we'll dry the gunpowder!"

In short, granulation technology involves turning gunpowder powder into granules, and mixing sulfur, saltpeter, and charcoal with water in a certain proportion, drying them into blocks, and then breaking them into small granules.

A few days later, Song Anxin and the others arrived at the outskirts of the border town again. The gunpowder formula had been readjusted, and the gunpowder packets were now filled with fine granules of gunpowder.

They specifically chose a huge rock today. Qingshan and Qingyun tied several packages of explosives to the rock, and then returned to the foot of the slope to light the fuse.

"Sizzle... hiss..."

The spark ignited and flew rapidly along the fuse toward the huge rock.

"Bang! Bang bang!... Bang!..."

A tremendous sound struck, and the rock that had just stood there was instantly shattered into pieces, with fragments flying everywhere, and even the surrounding soil was blasted into a charred black.

Several people peeked out from under the cover slope, their eyes wide with shock at the sight before them, followed by immense joy.

"My lady, the gunpowder is done! It's done!" Qingfeng and Qingyun exclaimed excitedly.

"Ah!...Aunt Anxin, it's a success! It's a success! This gunpowder is amazing! And you are amazing too!"

Yan Ping'er happily hugged Song Anxin and cheered loudly.

Lin Fenghe's face was also full of joy: "Mother, I will immediately send someone to call the General and the others over."

After General Yan, Yan Shuping, and Deputy General Lu saw the power of the explosive charge, their faces were filled with shock and disbelief. Although they had heard about the power of the explosive from Hui Gong, seeing it with their own eyes was far more shocking than hearing about it.

"Hahaha... With this gunpowder, what do the Huns have to fear? Lady Hui, wonderful, wonderful! This gunpowder is truly ingenious."

Yan Shuping laughed as he looked at Song Anxin with great admiration in his eyes.

"This gunpowder is fucking powerful! I really want to use it right now to blow those Huns to smithereens!"

Lu Pianjiang looked excited, as if he was ready to fight.

“I never imagined that such a divine artifact could exist in the world. I had doubts about you before, and I apologize to you.”

“..……..”

The generals, realizing what had happened, were extremely excited and discussed the explosives, all praising them highly.

General Yan's usually stern face flushed slightly, and as he looked at the gunpowder, which was bursting with intense light, he said to Song Anxin, "Hui Gongren, you are truly an extraordinary person! I admire you greatly, I admire you to the utmost."

Song Anxin looked a little embarrassed, after all, as a modern person at heart, these were just differences in the information she had received about the times.

The successful production of gunpowder gave the generals a glimmer of hope for final victory, and General Yan mobilized all the materials for gunpowder production in the northern frontier to begin mass production.

However, the northern frontier has limited resources, so there isn't much gunpowder that can be produced. Therefore, it is necessary to make full use of this gunpowder to annihilate the Xiongnu in one fell swoop.

These past few days, Lin Fenghe has been discussing battle plans with the generals in the main military camp. Song Anxin knows that she can't get involved in this, so she stays quietly in the tent.

Meanwhile, conflicts on the northern border became increasingly frequent, with small battles almost every two days and major battles every three days. The Huns were mostly victorious, which made them increasingly arrogant.

"General, the time is ripe, we can make our move."

Lin Fenghe looked at the map of the northern frontier battlefield with a calm light in his eyes.
