Liu Yijin walked helplessly to the cauldron and started to light the fire honestly.
"Miss Lan, is there a kind of medicinal powder that is colorless and odorless, and can also control people's minds?"
Lan Yuer pointed to the boiling liquid in the cauldron: "After the water evaporates, what is left is the powder you mentioned, and the effect is a hundred times better than what you said."
Liu Yijin's mind suddenly moved, "Why are you developing these things?"
"Doctors who save people can also kill people." Lan Yu'er said calmly: "Besides, who said I can't develop this thing?"
"Your Liu Mansion's defense force is so weak, and you are your enemy both inside and outside the court. I first think about the safety of the ladies."
Liu Yijin smiled and said: "Then you can't hand something to the enemy and let him eat it obediently."
"That can't be done."
Lan Yuer pointed to the things piled next to her: "Look at what those are."
Liu Yijin walked over suspiciously and was stunned: "You want to make black powder?"
Lan Yuer shook her head: "I can't do this, but there is someone in our family who can."
Liu Yijin asked doubtfully: "Who?"
"Meng Yao." Song Lian added something to the cauldron and said with a smile: "Meng Yao said she had come across these before, but she didn't know the proportions of the formula, but she wanted to try it."
Liu Yijin looked at the boxes of raw materials: "What are you going to do?"
Mengyao walked in: "I heard Liu Chang say once that the formula should be in these, but how to configure it, I may need to study it slowly, but it may take a while."
Liu Yijin sighed in his heart and stepped forward to take out three things: "Charcoal, saltpeter and sulfur, these three are enough. The specific ratio is also very simple. It depends on whether you want to make gunpowder or fireworks."
Mengyao chuckled and said: "Fireworks and firecrackers are just for viewing. They will be gone when they are set off during holidays. If only we could create the kind that can kill the enemy."
Liu Yijin couldn't help but take another look at Mengyao: "You know a lot."
"What's the point? As long as you experience many things, you will naturally hear something useful."
"Didn't your Excellency tell His Majesty about the black powder formula a few days ago? Several days have passed. If you still can't come up with it, Your Majesty will blame you. What will you do?"
Liu Yijin couldn't help but feel moved in his heart: "I'll leave the black powder matter to you."
"Now I have one more important thing to do. Let's study it together after the processing is over."
Lan Yu'er and the three ladies scraped the contents out of the cauldron and spread them out on the smooth ground. Lan Yu'er brought over a basin of something that looked like batter, then added the medicinal powder and stirred it.
"This is?"
Liu Yijin looked puzzled and said, "What kind of operation is this?"
"Make medicine."
Liu Yijin had a dark look on his face, "How can you kill someone?"
Lan Yuer rolled her eyes: "Didn't I tell you, this thing can kill people and cure diseases."
After everyone was busy, Lan Yuer handed a bottle of pills to Liu Yijin: "Twice a day, one pill at a time, it can regulate a man's energy and spirit."
"Cao, isn't this poison?"
Lan Yuer glared: "Two pills at a time, that's harmful. Do you understand?"
Liu Yijin was speechless for a while.
After packing everything, Lan Yuer walked into the room, and Liu Yijin followed directly. I happened to see Lan Yuer taking off her clothes.
"Liu Yijin, can you stop being so perverted!" Lan Yuer turned around and glared: "Go find your wife!"
Liu Yijin's face turned red and he hurriedly retreated.
Song Lian on the side laughed so much that she giggled: "You deserve it!"
After Lan Yu'er changed into fresh clothes and walked out, Liu Yijin stepped forward with a smile: "Miss Lan, I have something important to see you for."
"What's the matter? Tell me."
Liu Yijin told Zhang Bing's sudden madness, and Lan Yu'er thought for a moment: "This matter is a bit strange, I want to see it in person."
Liu Yijin took Lan Yuer and Mengyao directly to the prison of the Supervision Department.
After these two days of rectification, the Supervision Department has undergone a major change. The people assigned to key positions were all frustrated under Zhang Bing, and these people will naturally stand with Liu Yijin.
Yuan Shuo is now the person in charge of the Supervision Department in the Imperial Capital. He has jumped from a small wolf guard to the position of deputy head of the Supervision Department of the Imperial Capital. He is even more grateful to Liu Yijin in his heart.
"Sir, this is all Zhang Bing's confession, and it's all here."
Liu Yijin glanced at Yuan Shuo suspiciously. Zhang Bing was still hesitant before he left. It hadn't been an hour yet. Could it be that Zhang Bing had already surrendered them all?
When Liu Yijin read Zhang Bing's confession, he couldn't help but take a deep breath: "Is everything true?"
"I have arranged for people to go to Zhang's house to investigate. It is true that there is one hundred thousand taels of silver buried under the floor tiles in their kitchen. This is really part of it."
Liu Yijin hurried into the interrogation room and couldn't help but be shocked by the scene in front of him.
Lu Canghai collapsed on the ground covered in blood and gasped for breath, while Zhang Bing was hung up. What made Liu Yijin even more unexpected was that the person interrogating him turned out to be Xikun.
The clothes on Xikun's body had long been torn, and a long gash was cut on his face with a sharp blade, dripping with blood.
What surprised Liu Yijin was that Xikun seemed to be going crazy, with cold murderous intent in his eyes, and the whip in his hand was whipping towards Zhang Bing desperately.
With the pitiful screams, Zhang Bing trembled all over, "Xikun, you're going to die a f*cking death!"
Xikun smiled darkly: "I saw you were very excited when you whipped me just now. Now it's finally my turn. I will beat you two brothers to death!"
Liu Yijin looked at Yuan Shuo: "What's going on?"
"Sir, I just let them drink some tea respectively. Of course, there is a little something in the tea."
Liu Yijin looked at Yuan Shuo with strange eyes: "That's it?"
Yuan Shuo chuckled and said, "Your Excellency, you didn't see the scene at that time. Whoever drank the medicine became aroused, and all kinds of torture instruments were used to stimulate the madness. We couldn't stop them."
"But their problems were all answered."
Liu Yijin looked at the materials that were almost half a foot high on the table and couldn't help but nodded in admiration: "You are a talent!"
The scene of blood in front of her made Mengyao frown slightly and her face turned pale. However, Lan Yuer walked to the table as if nothing was wrong, gently picked up the powder packet on the table and examined it.
"This thing is actually similar to what I studied, but this kind of medicine has more intense properties."
Liu Yijin said: "Miss Lan, I asked you to come here just to see this situation."
Lan Yuer hummed, poured a cup of tea and handed it to Yuan Shuo, then motioned to Zhang Bing who was tied to the pillar: "Drink it for him."
Several black-armored iron guards poured the tea directly into it.
After a while, Zhang Bing seemed to be a different person, his eyes were scarlet and he was roaring again and again.
"Is this the case for King Su at the beginning?"
Liu Yijin nodded: "It should be about the same."
"Where did the original powder come from?"
Lu Canghai, who was paralyzed on the ground and was weak, looked at Xikun who was waving his whip indifferently and said: "This medicinal powder was actually developed by Xikun, because he is one of the three elders of Maitreya Buddhism."
What?
This news not only shocked Liu Yijin and others, but even Xikun, who was waving the whip, gestured for a moment, then roared towards Lu Canghai: "You are talking nonsense, I will kill you!"
Seeing the majestic inner strength that suddenly emerged from Xikun's body, he was completely different from before!
Liu Yijin knew that even if Xikun was not one of the three elders, he was still an important person in Maitreya Buddhism.
"Bold!" Several black-armored guards rushed forward, but before they could react, Xikun knocked back several people and grabbed Lu Canghai's neck with both hands like lightning: "How dare you slander the imperial official? I Kill you!"
Xikun's lightning speed made Liu Yijin understand that this guy was not an ordinary person at all. The dignified Shangshu of the Ministry of Justice was actually one of the three elders of Maitreya Buddhism. What kind of people were the other two elders.
Liu Yijin punched Xikun on the back. Driven by his fist, his violent internal force hit Xikun's back. What he didn't expect was that Xikun didn't react at all. .
"not good!"
Liu Yijin was alert and just about to retreat, Xikun turned around and looked at Liu Yijin indifferently: "Want to leave? It's not that simple!"
The violent aura came out and bombarded Liu Yijin directly.
Liu Yijin blocked with both hands, but the powerful fist still knocked him back several meters.
"Protect your lord!" A group of black-armored iron guards drew their swords and slashed at Xi.
"Catch him alive!" Liu Yijin shouted hurriedly: "Don't kill him, he may be one of the three elders of Maitreya Buddhism!"
