Abandoning concubines and raising children to seize the throne

Yunxiang Garden.

The newly planted seeds have sprouted, and the leaves are tender and green, which is very attractive.

Looking at these seedlings, Yin Qingxuan was in a good mood.

If they continue to be planted like this, within three to five years, these modern species will take root and sprout in Dazhou. This can be regarded as a change she has brought to the world.

Xiao Nanfeng was also very excited. He couldn't help pointing his little hands into the ground, raising his little feet happily, and kept babbling in childish words that Yin Qingxuan couldn't understand.

Ye Jingyu reached out and took Xiao Nanfeng out, took him into the field, rolled up his robe and squatted down, letting him touch the young seedlings.

Xiao Nanfeng was so happy that he couldn't help but pull with his little hands, suddenly grabbed a seedling, and pulled it out by the roots.

Ye Jingyu smiled and said, "I didn't expect Zhao'er to be so strong."

Yin Qingxuan couldn't help but said: "The emperor is too fond of him. How can he destroy the seedlings casually?"

Ye Jingyu stood up with Xiao Nanfeng in his arms and looked at his son with a smile on his face.

"He is only a few months old and doesn't understand anything. When he grows up, I will teach him the principles of governing the country."

Yin Qingxuan rolled her eyes. Although Xiao Nanfeng was young, he knew how to look at his face. He would still know what he was scolding.

If you continue to do this, God knows what Ye Jingyu will teach the child.

Ye Jingyu didn't take it seriously. After playing with Xiao Nanfeng in the field for a while, he put him in the stroller.

"It's windy here, so we'd better go back."

Xiao Nanfeng was also a little tired. He leaned against the stroller and pouted, his eyes half-closed, and he seemed a little sleepy.

The three of them were about to walk back when they suddenly saw a guard walking over in a hurry.

"Your Majesty, we have an urgent call from Tonggu Pass [-] miles away."

Ye Jingyu reached out and took the letter, and when he saw the contents, his face suddenly darkened.

"Trash, just a bunch of trash."

Yin Qingxuan couldn't help but ask: "What's wrong?"

Ye Jingyu said in a deep voice: "The Marquis of the North wrote to me, saying that Tonggu Pass will no longer be able to support it."

"Ah! If I didn't tell you before, could I have withstood it?"

Yin Qingxuan knew something about the topography of Dazhou.

Tonggu Pass is the main pass between Dazhou and Jiangwu. If it is broken here, Jiangwu will definitely drive in.

"With a shield array to counteract it, even if we can't defeat Jiang Wu, we won't be able to break the city. Could it be that the enemy has some other killer weapon?"

Ye Jingyu clutched the letter and said bitterly: "The letter said that they have built a siege vehicle that can throw boulders. Now two passes have been destroyed and are being repaired. If all passes are destroyed, Tonggu Pass will definitely not be able to be saved. , this old thief, the Marquis of the North, actually asked me to send the princess to him to alleviate the disaster."

Yin Qingxuan frowned, this is indeed a very serious matter.

As a woman, she naturally did not agree with the princess getting married.

After thinking for a while, he said: "Your Majesty, is there any gunpowder in Dazhou?"

Ye Jingyu was slightly startled, looked back and asked, "What is gunpowder?"

Looking at his expression, Yin Qingxuan knew that there was no such thing in this era!

"It is a very destructive weapon. It can explode and injure people and animals in a large area. If this thing is used, it may be able to scare those barbarians."

Ye Jingyu immediately asked: "How to make it?"

"Need to use nitrate, sulfur, and charcoal."

The night view of charcoal was well known, but saltpeter and sulfur were unheard of.

Yin Qingxuan explained: "It is not difficult to get nitrate. It is a white crystal similar to ground frost. It can usually be found on cliffs or salty areas, or in horse pens and pig pens. Sulfur can be found in natural sulfur mines. , if you can’t find sulfur, you can also use realgar instead, and mix these three substances together to get explosive gunpowder.”

Yin Qingxuan also described the general appearance of the sulfur mine. She had only seen these in books, and she was not sure about the specifics.

Ye Jingyu pondered for a moment and asked, "Is gunpowder really that powerful?"

Yin Qingxuan lowered her eyes and said, "I saw it from a classical book, and it is indeed recorded in this way."

Ye Jingyu's eyes suddenly shone with light.

"Then you can give it a try. I will send people to look for these things. I still need my concubine's guidance on how to mix them."

Yin Qingxuan bowed slightly.

"I, my concubine, should do my best."

"Okay, you take Zhao'er back to Jinwu Palace first, and I'll go back to the imperial study to send someone to take care of things."

After Ye Jingyu finished speaking, he quickly walked out of Yunxiang Garden.

Looking at his hurried back, Yin Qingxuan sighed.

When the two armies are fighting, casualties are inevitable. Now that she is in Da Zhou, she naturally has to plan for Da Zhou's safety.

He immediately said to Xiao Anzi: "Let's go too."

Returning to Jinwu Palace, Yin Qingxuan immediately went to space to find a book about gunpowder.

Although Yin Qingxuan's major is civil engineering, she has also dabbled in this aspect, but she doesn't know how to deploy it. After all, she is not a munitions professional, so it is impossible for the school to let students conduct gunpowder experiments.

Fortunately, the space is omnipotent, not only the supplies are complete, but also all the books are available. Yin Qingxuan roughly wrote down the percentage of the allocation, and then retreated from the space.

In the next few days, Ye Jingyu seemed to be very busy and did not come to Jinwu Palace again. Yin Qingxuan wanted to ask, but was afraid of being accused of chaos in the harem, so she endured it.

Ever since she said goodbye to Ye Zhan, she always remembered what he said.

Although I have space and can gain 5 minutes of strength, I can't just look for trouble. It's better to be low-key.

I have been with Xiao Nanfeng every day these past few days, and I have been living a leisurely life.

After finishing breakfast that day, I was about to take Xiao Nanfeng out to eat when I suddenly saw Su Caiwei Lihua running in with rain.

"Concubine Yao, save me!"

Yin Qingxuan asked in confusion: "What's wrong?"

Su Caiwei cried and said: "I just received the news that my father was assassinated last night. I also asked the empress to ask the emperor for permission to go home for the funeral."

Yin Qingxuan couldn't help but be surprised.

"Assassinated? Did you...hear that right?"

Su Caiwei's biological father was Su Huan, the Minister of Rites, and he planned the Queen Mother's birthday. Why did he die suddenly?

Su Caiwei was already crying.

"There is absolutely no mistake. I also ask your Majesty to ask for a favor on my behalf and let me leave the palace to see my father off. I will definitely tie a grass ring in my next life and repay my Majesty well."

When Yin Qingxuan was a eunuch, Su Caiwei did feel sorry for her, but she didn't get any advantage from Yin Qingxuan. Now she is Yin Qingxuan's biggest customer, and for the sake of money, Yin Qingxuan has to help her.

"It's okay to beg for mercy, but the emperor is still in the court now. I'm afraid he will have to wait for a while before going down to the court."

Su Caiwei said excitedly: "Thank you, Concubine Yao, I can wait for the emperor to come to court."

Yin Qingxuan nodded and said, "Okay, I'll be there at noon."

Su Caiwei was immediately grateful.

"I'll go to the imperial study room first."

Looking at Su Caiwei's anxious back, Yin Qingxuan frowned.

What's going on? Why is Beijing so uneasy recently?
