The night in Liaodong is extraordinarily long, and the northwest wind is whining, carrying snowflakes across the grassland. The weather was getting colder and colder, and Yu Ruoxu would sometimes wake up in the middle of the night and hear the wind blowing on the window lattice, making a rustling sound. She counted the days as if ...... In a few days, it will be Chinese New Year's Eve.

The frostbite on her feet is not too severe, and it has been almost good for a few days, but the knife wound on her hand is quite dangerous, and the wound heals slowly in winter, but fortunately, the weather is cold, and there is no need to worry about suppuration.

In the past few days, Liang Jin has been extremely busy with the matter of flying ants, and she often wakes up and sees that the light in the study is still on. But no matter how busy she is, Liang Jin will come to see her. Sometimes she slept in a daze, and felt someone around her help her pinch the corners of the quilt, and then tried her forehead with the back of her hand. The movements are stoic and gentle, the same as the gentle and polite manner that the man has always had.

After a few more days, the wound on her hand finally began to scab, and the doctor instructed her while changing the dressing, "The wound has begun to scab over in the past few days, Miss Yu must pay attention when she sleeps at night, remember not to scratch it, if the scab is broken, it will be even more difficult." ”

Yu Ruoxu nodded, "I know, thank you doctor." ”

"Miss Yu is polite." The doctor accepted the medicinal herbs and said, "Miss has a fever this time, and the knife wound is just an introduction, mainly because of the usual excessive worry. ”

Yu Ruoxu was stunned for a moment, and said with a smile, "Doctor Xie mentions." ”

I had just fought with Xu Xiao'e a few times before, and the road to Liaodong was bumpy this time, and I was injured by a knife before I had time to catch my breath. She couldn't help but have a headache, it seemed that she had indeed been unlucky lately, and had encountered too many troubles.

"The doctor told you to relax just now, why did you start frowning as soon as he left?"

Yu Ruoxu raised his head when he heard this, only to see Liang Jin walking into the house, and the black big coat was stained with snowflakes, which made his face as white as jade.

"So early today?" Yu Ruoxu smiled, straightened up, and wanted to sit up from the bed, "It looks like something happy has happened." “

Liang Jin hurriedly held her down, "Don't move, I have a cold on my body, go to the stove to bake first, so as not to spread the wind cold to you." With that, he walked straight to the stove, untied the big sheath, and put his hand on the fire to roast it, "Why is there no one around you?" What about Iron Maiden? ”

"She went to the kitchen to help me make medicine." Yu Ruoxu smiled, "Tell me quickly, what happened to me?" “

Liang Jin seemed to be in a good mood and jokingly said, "Guess? ”

"Can make our prince feel so good......" Yu Ruoxu deliberately lengthened her voice, "Could it be that he has been promoted to the rank of official and has become a third-grade waiter?" “

Before Liang Jin could speak, Yu Ruoxu sighed, "I didn't expect that the prince already has the hereditary title of the Hou Mansion, but he is not satisfied, he has to be a first-class member to be willing." ”

Liang Jin seemed to be choked, angry and funny, "I don't believe you can't guess?" ”

Yu Ruoxu raised her eyebrows and looked at him with a smile, "That'...... Could it be that someone presented a rare treasure to the prince? ”

Liang Jin really couldn't help it, got up and walked over, sat on the edge of her bed, and looked at her with a smile, "No, continue to guess." “

Yu Ruoxu saw his shadow hanging over him, and his face immediately turned red, "You...... What are you doing? ”

Liang Jin's expression was as usual, "I'm asking you." “

Yu Ruoxu is becoming more and more unable to see through the person in front of her, he was obviously a gentleman before, why is it now...... Became such a scoundrel?

But...... He really didn't do anything.

She looked into his eyes, and there was a narrow light shining in her dark and shiny pupils, staring at her heart, and she had no choice but to raise her hand in surrender, "I was wrong...... Is it the flying ant thing that has been solved? ”

"That's right." Liang Jin straightened up slightly, "This time, Qiao Huanyan can be regarded as the first contribution." ”

"What's wrong with him?" Yu Ruoxu saw that Liang Jin's expression became serious, and she also restrained her joking heart, and asked Zhengse.

"The **** mentioned that the victims of Henan and Hebei may have earthwork to deal with flying ants, I rushed to the camp to take a look, and found that many soldiers had begun to burn white grass, and the flying ants really subsided some, not as rampant as in the past." Liang Jin said, "When I asked, it was really Qiao Huanyan's first proposed method. ”

"White grass?"

"Exactly." Liang Jin said in a deep voice, "General Yang and I summoned him overnight, and after asking carefully, we learned that he had personally experienced the locust plague, and the situation at that time was even more tragic than now. ”

Yu Ruoxu's eyes lit up, "That's why he mentioned burning white grass." ”

"It's the strongest smell you can find on the prairie." Liang Jin was still a little worried, "But Bai Mao is not powerful enough after all, and can only temporarily curb some of the flying ants, Qiao Huanyan said that the most effective is wormwood, General Yang wrote an excerpt overnight yesterday, asking the imperial court to quickly transport a few truckloads of wormwood." ”

"But is it too late?" Yu Ruoxu couldn't help but ask, "...... the imperial court?"

Liang Jin nodded, "I'm also worried about this." This icy and snowy, the grassland is withered, the white grass we can use is limited after all, and it won't last long, if the court delays for a few more days, our soldiers will probably have to suffer this unwarranted disaster again. “

"The smelly ......," Yu Ruoxu pondered, "we have to make another plan." “

"yes." Liang Jin frowned, "This is just a temporary solution, and we still have to wait for the support of the imperial court." Xianbei's move is intended to shake the morale of the army, and we must not be seen by them. “

Yu Ruoxu couldn't help but look out the window, only to see a white expanse, nothing.

The battlefield where the two armies confronted each other, the blood-sucking flying ants, and the pungent smoke......

"Liang Jin!" Yu Ruoxu suddenly straightened up and grabbed his arm excitedly, "How about using sulfur?" “

"What?"

"If the white grass is exhausted and the supplies of the imperial court have not yet arrived, then use the sulfur in the artillery." Yu Ruoxu analyzed, "I heard my father say that our batch of artillery is made of red sulfur from Dayan Mountain, which has a pungent smell and full of power, and the color is golden red, even if it is mixed with saltpeter charcoal, it is very easy to identify." “

Liang Jin was stunned, "You mean, use sulfur to smoke flying ants?" “

"You can give it a try." Yu Ruoxu nodded and said, "Sulfur is expensive, and good things should be used in ideas...... For example, it was left in a flying ant nest near the camp. “

Liang Jin's eyes were full of appreciation, "What you said makes sense, I'll ask someone to try it." With that, he stood up, "Thank you!" “

Yu Ruoxu laughed out loud, "Thank you?" “

Liang Jin put on a big hat and smiled at her, "The only one who can solve my worries is Ruoxu." ”

With that, he hurried out of the house.

Yu Ruoxu smiled and shook his head, "What a nerd." “

Within a few days, Liang Jin came to sue her, saying that sulfur was indeed more powerful than white grass, and they only dismantled two cannons, and the red sulfur in them smoked several ant nests they found into a ball of black charcoal, and the smell of white grass smoke had suppressed some of the flying ants, and the current crisis finally waited for the control.

As they expected, the imperial court's supplies arrived belatedly, and they arrived after a delay of nearly ten days on the official road. Yang Zhen ordered the whole battalion to burn wormwood, and for a while, the smell of wormwood was overwhelming, and even Yu Ruoxu, who was recuperating in the army mansion, was not choked by the smell of smoke and coughed.

When Yang Yuqing visited again, Yu Ruoxu was covering her mouth with a handkerchief, coughing profusely.

"Miss Yu is afraid of smoking?" Yang Yuqing looked calm and relaxed, but it was in stark contrast to Yu Ruoxu's wolf bèi.

"I'm just not used to it." Yu Ruoxu wiped the tears she coughed up and smiled reluctantly.

Yang Yuqing said lightly, "Compared with the smell of gunpowder on the battlefield, I don't know how much lighter, but Miss Yu is the daughter of the boudoir, so she is not used to this pungent taste." “

Yu Ruoxu was stunned, "Miss Yang is a heroine, I am just a deep girl, and I can't be compared with Miss Yang." “

"I heard that the idea of using sulfur to smoke the ant nest this time was mentioned by you to the prince?" Yang Yuqing took a sip of tea and asked.

"It's just a coincidence." Yu Ruoxu smiled and didn't say much.

"The prince treats you very specially." Yang Yuqing sighed and stared at her deeply, "When I was in the camp, he mentioned you more than once, saying that although you are in the boudoir, you have the world in your heart. “

Yu Ruoxu didn't expect Liang Jin to mention her in front of outsiders, "The prince praised it falsely." “

Yang Yuqing saw her indifferent look, and suddenly felt a little flustered in her heart, "You two, are you really just confidants?" After speaking, she felt that it was inappropriate, and hurriedly explained, "Don't get me wrong, I mean...... The prince has always been gentle and polite, but I didn't expect him to be so ......"

Yu Ruoxu couldn't help but smile when she saw her slightly at a loss because of her speech, "Does Miss Yang have a marriage contract?" ”

Yang Yuqing didn't expect her to ask herself, and frowned for a while, "Why did Miss Yu suddenly ask about this?" ”

"The prince is different from other Liang disciples." She said quietly, "He is the person I know, the most worthy of a young gentleman among the living people." ”

Yang Yuqing seemed stunned, "A living person? ”

Yu Ruoxu didn't speak, but there was a slight desolate look in the corners of her eyes, and she looked at her quietly.

The two were silent for a moment, and Yang Yuqing said, "It's unfair for you to treat him like this." ”

"Miss Yang misunderstood." Yu Ruoxu smiled, "He has been suffering from himself, so what he needs most is a wholehearted companionship, not a confidant who is also a fallen person at the end of the world." “

After that, Yu Ruoxu sighed again, "This has nothing to do with public unfairness." “

Yang Yuqing was speechless, lowering her beautiful eyes, "I don't know about the previous things, and I don't want to know, but as you said, what he needs is wholehearted companionship, at least for this, I have the confidence to outperform you." “

Really...... It's still a girl who is just starting to fall in love.

Yu Ruoxu smiled, "You are far superior to me, not only in this regard. “

"I came to you today to tell you about the sword technique." Yang Yuqing paused, "I asked a lot of people to inquire, the kind of four-like knife technique you mentioned is indeed extremely rare, and almost no one has used it in the rivers and lakes." “

"Almost?" Yu Ruoxu straightened up and sneered, "That's right, the fewer people who use it, the more convenient it is for us to investigate." ”

Yang Yuqing nodded and said, "That's right, the last time someone saw this knife technique was twenty years ago. ”

Yu Ruoxu was taken aback, "Is it possible...... Something to do with the eunuchs? “

"This is the sword technique used by Zhao Gelding's secret guard."
