"This is saltpeter, an ore with many uses. Fireworks and firecrackers are commonly used. In addition, saltpeter absorbs heat and cools when dissolved in water..."
In order to survive the hot summer without air conditioning, Lihua went to the Weaving Bureau to look for saltpeter mines.
But after all, the palace does not need to be convenient outside. The response was only received not long ago, not long after she used it.
Unexpectedly, Lihua left only for a short time and when she came back, she found that the evildoer had dismantled her simple air conditioner.
At this moment, Lihua briefly explained how to use refrigeration for Yuchigong, and used freshly cooked sour plum soup to cover up for him how to quickly achieve the icing effect of fruit drinks.
Yuchi Gong picked up the ice-cold sour plum soup and looked at her with sparkling eyes: "Who is my concubine's disciple, who knows so much?"
This woman always filled him with surprises. He didn't know what other talents he had.
It is a very happy thing to be praised by smart people, especially when the praise comes from an emperor.
Lihua modestly said: "My Lord Long Live has given me the award, but I have studied extensively and learned some superficial skills. As for where I learned from, it's hard to say, because I have too many teachers."
Counting from the present time to the time after time travel, plus those who were angered by her, there are quite a few, and it’s difficult to describe them in detail.
Yuchi Gong couldn't help but laugh, no wonder the little thief has learned a lot, that's how it is.
He took a sip of the sour plum soup and felt that it tasted good. It must be something the Queen Mother liked to drink, so he asked someone to send some to him.
After giving the order, she looked back at Lihua with gleaming eyes: "I have heard that saltpeter is used in fireworks and firecrackers before, but I never paid much attention to it. Today I saw what saltpeter looks like. You just said that saltpeter has many uses. Apart from that, you can
Is there any other way?"
Lihua's heart tightened. She knew that the monster had a bright mind, but she didn't expect it to be so bright.
She just briefly mentioned that it has many uses, and people took advantage of the loopholes in her words and asked her.
The development and utilization of saltpeter in this era was extremely low. It was generally only used to make firecrackers and fireworks, and the rest was also used in traditional Chinese medicine.
But the biggest use of saltpeter is to make gunpowder and explosives, which are very lethal. In this era of cold weapons, it is undoubtedly the most powerful weapon.
The reason why gunpowder has not been used in this era is not because we are not aware of it. After all, we can already make firecrackers.
That's because stable and controllable explosives haven't been developed yet, and you have to be careful when making fireworks, let alone gunpowder and explosives that are hundreds and thousands of times more powerful.
I'm afraid that no explosives that can really be used as weapons have been developed yet, and the people who researched them have been killed countless times, and the damage was done in a wide range, not just one person.
When Lihua looked through the history books of this dynasty, she discovered a huge explosion in a fireworks house, resulting in heavy casualties.
Since then, the imperial court has clearly stipulated that fireworks and firecrackers are not allowed to be made in areas where people live densely.
Now Yuchi Gong asked about other uses of pear saltpeter. It was obviously not a simple question.
As an emperor, what he wants to know most is the big use that is beneficial to the country, rather than the small use for fun.
Lihua went through these thoughts in her mind for a moment, blinked, and said naturally: "Maybe there is, I will tell you after I study it."
To talk about powerful explosives, Lihua still needs to carefully consider all aspects. She can't just talk quickly and be irresponsible, but she doesn't have to say it to death.
Yuchi Gong couldn't help but reached out and tapped her forehead: "My beloved concubine is still the same as before."
As smart, cautious and cunning as ever, this little thief.
Lihua said "ouch" and touched her forehead pitifully and cried out that it hurt.
Yuchi Gong laughed heartily.
He knew that Lihua didn't want to talk, so he didn't dwell on the issue.
The two chatted for a few more words, and after Yuchi Gong drank all the sour plum soup, he was ready to leave. He had to go back to deal with the government affairs.
Before leaving, he wanted to "borrow" a simple air conditioner from Lihua, planning to have someone copy it and make more for use in Cangchen Palace and Zhuangning Palace.
Lihua was very generous: "Long live the Lord, I can take it, but I plan to give the Queen Mother something better. I'm afraid I won't be able to use it after a while."
Lieutenant
Chi Gong raised his lips and smiled: "I'll wait and see."
As for whether the Queen Mother was going to suffer, Yu Chigong felt that it would be good for his Queen Mother to have a thief in charge, so that when he was busy with government affairs, his Queen Mother would be left unattended and waste his own health.
Hanxiang Palace.
Ever since the news of Wu Fang'er's death came, Chen Sisi knew that the development of the matter was beyond her imagination and was heading in an uncontrollable direction.
She understood that something must have gone wrong, so her heart was weighed down by a heavy boulder and she was always in a state of uneasiness. She didn't sleep much last night and woke up early today.
Chen Sisi tried his best to calm down and restrained himself from sending people out to inquire about the news, so as not to let others see his impatience.
Therefore, when she learned the news that Lihua had been released, she was a little stunned.
Hearing that a slave died under the pear blossom, Chen Sisi instinctively felt that something was wrong, but then he thought about it and understood.
This is abandoning pawns to protect chariots. No wonder people are released.
Soon after, Chen Sisi learned that the emperor had sent two young eunuchs to serve in Tingli Courtyard. Now she couldn't sit still at all.
She personally took her personal maids and went to the main palace with gifts, euphemistically calling her the queen of the main palace to relieve her boredom.
Because Chen Sisi is the niece of the same clan as the Queen Mother, the empress of the main palace gets along quite well with her.
After the two parties exchanged pleasantries, the empress in the main hall took the initiative to lament Wu Fanger's death, but her tone contained a hint of schadenfreude, a hint of lingering fear and happiness.
This is exactly Chen Sisi's purpose. She knows that this important matter will inevitably be mentioned wherever she goes in the palace.
She continued to lament: "Me and Wu Meiren were sisters at Qunfang Hall, but later on she gradually became estranged from me after she awarded the beauty. But I still think of her as a sister in my heart, but now..."
Speaking of her sadness, she wiped away tears: "I don't know who committed the murder. Has the Criminal Division caught the real culprit?"
When it came to the murderer, the empress of the main palace comforted her, and then she couldn't help but mention Lihua: "Tsk, I originally thought it was Tingliyuan Wumei who did it, but now that she has been released, I can't say for sure."
Chen Sisi paused as he wiped his tears: "If you put the person back, doesn't it mean he is innocent? How can you not be sure?
The empress of the main palace smiled slightly and waved, asking her to come closer.
Chen Sisi hurriedly came over.
Then the empress of the main palace said to her mysteriously: "Didn't Long live the Lord send two young eunuchs to Tingli Courtyard? There is a profound meaning in it. It is inevitable for you newcomers to the palace not to know these things..."<
/p>
Let’s talk about those bastard things that the young eunuch of Cangchen Palace did in the past.
The main palace empress gritted her teeth and concluded: "You think sending these evil stars there can be a good thing."
Chen Sisi was confused when he heard this. It was the first time he knew that the young eunuch in the palace was so hated by the palace concubine.
But those bastard things he did sounded really bastard...
The empress of the main palace was very satisfied with her reaction and shook her fan: "Besides, didn't Wu Meiren leave a slave under her? There is an old saying that when the tree falls, the monkeys will scatter. We outsiders don't know Wu Meiren's current situation, but
Isn’t it the best indication that her servants choose to leave at this time that she is in a bad situation?".
"Your Majesty, what you said makes sense." Chen Sisi agreed, hiding his thoughts.
