Yuan Xin left the house and walked aimlessly on the street.
He felt uncomfortable in his heart, as if he was being pulled by something.
Meng Han, I'm sorry, I just said yesterday that I will trust you for the rest of my life, but today I lied to you.
The vows I made cannot withstand the wind and rain.
If you find out, will you be sad or unhappy?
Will you blame me?
I hate my own powerlessness.
Sorry, please forgive me this time, I am really helpless.
After tonight, I will definitely risk my life to protect you, and I will not let you suffer any injustice again.
The street was quiet and no one was seen.
Yuan Xin was thinking about Meng Han and Tianwei Tower, so he headed towards Tianlu Street by accident.
When he came back to his senses, he was already standing in the middle of Tianlu Street.
The wide and clean streets are deserted, whether it is the noisy Yong Seng Street full of market atmosphere or the gold-filled Tin Lok Street where celebrities and nobles come and go, whether it is a small stall for survival or a gorgeously decorated storefront, whether it is a conspiracy or a heart attack.
All good thoughts were shrouded in the darkness of the night without distinction.
Yuan Xin flew up to the roof and looked down at the scattered houses on this street and the neatly laid bluestones on the street.
Everything was just like that year, nothing had changed.
What has changed is that people like us come and go, whether they are concerned or determined, whether they cry or laugh, whether they are sincere or fake.
Things are different and people are different.
It’s been a few years since I left you, it’s been a few years since I’ve set foot on this street again.
I can’t remember clearly, I really can’t remember, I can’t even remember your appearance.
I did it, I can really forget about you.
Yuan Xin had been sitting on the roof, looking at the sky and the ground.
It was a unique feeling to be on the street at night.
It wasn't until the middle of the night that a man in black flew over and landed next to Yuanxin.
He handed Yuanxin an account book and said coldly, "It's what you want."
Yuanxin was stunned for a moment before he came back to his senses.
The visitor had already put the book in Yuanxin's hand and left.
Yuanxin was really slow to react.
He stood up and was about to leave.
The voice just now echoed in his ears.
It was very familiar.
It was you.
Is that you?
Yuan Xin wanted to chase after him, but the man in black had already disappeared.
Yes, so what?
Yuan Xin stopped arguing, got off the roof and went back home.
When they arrived at Qiu Shuangyuan, the lights in Meng Han's house were still on.
Yuan Xin went in and found Meng Han asleep on the table.
She has been worried about me, but I have been thinking about someone else all night.
Yuan Xin felt guilty for a while, carried Meng Han back to bed, quietly covered herself with a quilt, and returned to her yard.
When Menghan woke up, Yuanxin had already had breakfast and came to Menghan's room to study the list.
As soon as Meng Han opened her eyes, she exclaimed in surprise, "Yuan Xin, you are back.
Why did I fall asleep?
What time is it now?"
"It's still early.

If you're sleepy, just sleep a little longer."
"Are you okay?"
Yuan Xin stroked her hair lovingly, "What's going to happen to me?
Look at this, I got it back."
"Wow, the complete record of the Ritual Music Hall is in storage.
It's really amazing.
Now I'm saved."
Meng Han suddenly became energetic.
Yuanxin frowned, and after looking at it for half the night, he didn't see anything interesting.
"There are very few words about liquid, and I really can't see anything in it that can dissolve metal."
"Then did you find anything strange that shouldn't be there after entering the Liyakukan Music Square?"
"There is something suspicious."
Yuanxin picked up the book, "Here, this is what entered the Ritual Music Hall three nights ago, that is, the afternoon when the emperor announced the banquet for the emperor's relatives."
"What are they all?"
The ancient characters were difficult to read, and there were no punctuation marks, and they were written vertically.
Meng Han felt dizzy just looking at them, so she had to ask Yuan Xin.
Yuan Xin pointed to what was recorded in the book, "The cloth, clothing, and musical instruments are all normal, but the large amount of green vitriol is very unusual."
"Green vitriol" Menghan searched quickly in her mind, but she didn't have any impression, "What is it used for?"
"Green vitriol is a medicine that replenishes blood."
"Could it be that someone was injured and bleeding because of the medicine?"
"Probably not," Yuan Xin shook his head, "because the amount of green vitriol is too large, and if someone is really injured, they won't only need green vitriol."
"Yes, there is definitely something wrong with this green vitriol, and the date also matches.
The emperor just issued an order to prepare a banquet three days ago.
Yuanxin, go find someone to buy some and show it to me."
"Okay, you should get up and have something to eat too."
After Yuan Xin went out, Yu Liu came in to help Meng Han get up and freshen up.
Meng Han just drank a few mouthfuls of porridge, then remembered that Cheng Zheng's jade had not been returned to him, so he hurriedly ran out with the jade.
Cheng Zheng was waiting for her.
He didn't see her leave the house all night, and he didn't give the jade to anyone.
Is Yao Menghan really just an eccentric girl?
Menghan came back and continued eating.
When Yuliu packed up the cups and plates and left, Yuanxin came back and put a paper package on the table, "This is green vitriol."
Menghan couldn't wait to open the paper package and saw a kind of crystal green crystal.
Menghan pinched it and looked at it carefully, "There should be copper in it.
The color of copper ions turns green."
I only remember so much, and I don't know.
Easy, thank you to my chemistry teacher.
But this has nothing to do with sulfuric acid.
Could it be that this guy is copper sulfate?
Menghan muttered something alone, but Yuanxin couldn't understand it, "What are you mumbling?"
"I'm studying this green vitriol, but I still have no clue.
What should I do?
Yuan Xin, am I going to die?"
Meng Han cried sadly.
"Even you can't.

I guess it's really dangerous this time."
"You think highly of me.
I dare say that in your heart, everything I can't do is unanswerable."
Meng Han was so heartless that he couldn't hear anyone praise him.
"I've always looked up to you.
You're like a god to me."
Yuan Xin also climbed up whenever he was given a stick.
Meng Han sighed, "Sister Fairy is going to fall into trouble this time."
Yuanxin said confidently, "There will always be a way.
I believe you will turn disaster into good luck."
"I asked you, where does this young man get his confidence?
You are more sure than me about things that I don't even know about."
Yuan Xin smiled cheerfully, "With Lord Marquis under my protection, what can happen?"
Meng Han immediately stood up and called Yuan Xin, "Okay, you have been praising me for a long time, but you are praising yourself.
It's a waste of my girl's feelings."
Yuan Xin backed away continuously, holding his hands in front of him: "Don't hit me.
If you hit me, who will give you advice?"
Meng Han stopped her hand and asked, "Do you have an idea?"
Yuan Xin said with a stern look, "Yes, a little bit."
Meng Han punched her hard again and said angrily, "If you didn't tell me earlier if you had an idea, I would be afraid of harming my aunt."
"Okay, let me tell you.
Du Ruo didn't talk about the making process of Dragon and Phoenix the night before yesterday.
I think since she knows so clearly, she must know where the hydrogen inside comes from.
Let's go to the cell to explore. ” Meng Han nodded repeatedly, "That's a good idea.
Forget it, for the sake of your contribution, I will spare you this time."
Yuan Xin bowed deeply and said, "Thank you, madam."
Meng Han was impatient, "Hurry up and prepare the car, we'll go right away."
Yuan Xin hesitated and said, "Um, do you still have my brother's jade?"
"I went to pay him back without eating, what's wrong?"
"Did he say anything?"
"No, just a few polite words, thank you for keeping me in mind, what's the matter?"
"It's okay.
I'm afraid you'll forget about it while you're busy.
We are quite careless, so it would be bad if we lose it again."
Yuan Xin smiled reassuringly.
The two of them got on the carriage and went to the prison cell of the Criminal Department.
Fortunately, Yuan Xin was also a man with a title, and the emperor did not prohibit Du Ruo from visiting when he was detained, so the two of them got in smoothly without much effort.
Du Ruo took off her hairpin and wore a prison uniform and sat in the corner.
After the jailer opened the door, he reminded them to hurry up.
Yuan Xin gave the money and the jailer went out happily.
Hearing the sound of the door opening, Du Ruo raised his head and recognized Meng Han at a glance, "Girl, it's you."
"It's me."
"Du Ruo's life depends on the girl's rescue.
Du Ruo is extremely grateful."
Du Ruo said and wanted to salute, but Meng Han hurriedly helped him up, holding Du Ruo's hand and comforting him, "Du Ruo, don't worry first, I will definitely save you. out."

"Yes, Du Ruo believes in the girl.
When we get out, Du Ruo will definitely repay her with a spring of water."
Du Ruo shed tears as she spoke.
"I have something to ask you, and I hope you must tell me, because it is related to both of our lives."
Du Ruo nodded, "Girl, please speak."
Meng Han asked bluntly, "Where does the gas filled in Dragon and Phoenix come from?"
"This" Du Ruo hesitated.
Meng Han held Du Ruo's shoulders with both hands and looked directly at her, "What, you won't tell me?"
"It's not that I don't say it, it's that I can't explain it clearly.
I don't understand what they are doing at all."
"It doesn't matter, just tell me what you know."
Du Ruo said eloquently, "I saw the master ordered someone to buy a lot of green vitriol," Meng Han nodded, yes, Green Alum was not wrong.
"They sent green vitriol into the alchemy room," Alchemy oh, my god, some people believe in this too "I prepared two more basins of water and a lot of fine pieces of iron."
"No more."
Meng Han thought this was just the beginning, but Du Ruoyou had no intention of speaking again.
"Master, they were drawing the gas out of the alchemy room.
I don't know.
I only saw these things they brought in."
Menghan nodded, "Okay, I understand."
Du Ruo asked eagerly, "Is it useful?
Can you help me out?"
Meng Han said firmly, "It works, don't worry, you will definitely be able to get out."
Du Ruo burst into tears, saying to Menghan more like saying it to herself, "Okay, I believe in the girl." sjgsf0916:
