I made the villain right.

Half a minute later, Du Xuan came over with tea. When he was about to go into the house, he caught a glimpse of Fan Hua sitting in the pavilion in the yard, his mind wandering.

So he quickly changed his route and walked towards the pavilion. After hearing the footsteps, Fan Hua came to his senses and glanced at Du Xuan slightly.

Du Xuan put down the teapot, and Fan Hua immediately poured himself a cup of tea. The hot tea fell into the cup, with smoke rising above the tea and the fragrance of tea filling the air, refreshing the heart.

Fan Hua waited for a while before picking up the teacup and taking a sip of tea.

Du Xuan fixed his eyes on Fan Hua's face, trying to see through his expression how he felt. He found that at this moment, he had relaxed his brows and eyes, and looked calm and indifferent.

It seemed that he had figured out what had been bothering him before.

Fan Hua's eyes were complicated, and he asked, "What's going on at the Prime Minister's Mansion?"

Du Xuan let out a chuckle. He looked at Fan Hua and said, "Most of the houses in the Prime Minister's Mansion were burned down. Now he is hiring people to build new houses. He has no time to take care of other things. Even if he wants to find the arsonist to vent his anger, he can't find us."

When he and his master set the fire last night, they were both masked, leaving no clues, so they had no way to investigate.

Xiao Hong, the only person who had fought with Fan Hua, would never have thought that Fan Hua came to Kyoto City, let alone know that the person that night was Fan Hua, whom he both hated and feared from the bottom of his heart.

"From now on, have our people quietly monitor the Prime Minister's Mansion and be careful."

"Yes," Du Xuan said respectfully.

The Prime Minister's Mansion is now his prey, and he will feel at ease only when the prey is in front of him.

Fan Hua felt that for someone as arrogant as Xiao Hong to be willing to commit himself to Qin Yixian, there must be some unspeakable secret between them. Moreover, Qin Yixian was extremely cunning and, judging from his powerful means, he was definitely a difficult person to deal with.

The reason why Xiao Hong secretly made drugs beforehand had not been found out yet. He always felt that this matter was not that simple. Xiao Hong had just escaped from Fengyun Pavilion, and then he went to Kyoto City to seek refuge with Qin Yixian. It seemed that the two of them had secretly colluded and planned for a long time. This made him guess that the drug making might be related to Qin Yixian.

"Also, send someone to follow Xiao Hong secretly. I need to know his every move," Fan Hua suddenly said.

"Master, are you planning to deal with him secretly?" Du Xuan asked doubtfully.

"Xiao Hong's previous drug manufacturing matter has not been clarified yet, so let's keep him for now. I'm more curious about what secrets are hidden between Xiao Hong and Qin Yixian." Fan Hua's lazy voice reached Du Xuan's ears.

Hearing this, Du Xuan said thoughtfully: "Master thinks that Xiao Hong's secret drug manufacturing is related to Qin Yixian." Du Xuan was surprised, "If this is true, then Qin Yixian is obviously up to something and is planning something shameful."

Fan Hua looked calm, took a sip of tea, and said nonchalantly: "Well, so I am quite curious"

afternoon.

When Shi Jin went to see Xu Ruogu, she found that he had grown a lot taller in the past few months, and his previous clothes seemed a little short, so she planned to get him some new clothes, and also buy some clothes for herself.

It just so happens that Fan Hua’s betrothal gift included dozens of horses, which can be used now.

After Shi Jin arrived at the warehouse, she saw that the warehouse was filled with betrothal gifts sent by Fan Hua. She couldn't help but look surprised. After a moment's hesitation, she began to select. After a while, she came out of the warehouse with a few pieces of cloth, humming a tune and walking briskly towards the direction of Xiyuan. She was in a particularly good mood.

Not long after she left, a person came out from behind the corner.

Aunt Zhao looked at Shi Jin, who looked happy, her eyes gradually dimmed, and she tightly grasped the embroidered handkerchief in her hand.

There was a light pinch mark on her neck, and although it was covered with thick powder, it was still visible.

She was not from a remote mountain village, but a spy sent by Qin Yixian into the general's mansion. She was also the one hiding the most secrets. All the excuses, such as the life-saving grace and being driven out by her family because of her reputation, were a trick to deceive Shi Wei into taking her in.

Shi Wei had something that Qin Yixian wanted, so he made all the plans and let her ambush in the general's mansion and do things for him, so as to implement his plan.

If a spy fails to provide useful information to his master, he will die.

Because she failed to promptly inform Qin Yixian that Shi Jin had already been engaged to Fan Hua, some of his plans failed and he was so angry that he wanted to strangle her to death. Fortunately, he felt that she still had some value, so he let her go.

Qin Yixian assigned her a new task and asked her to stay in the general's mansion to continue working for him and atone for her sins.

Rumor has it that the Shi family has a secret book of formations, which allows Shi Wei to kill countless enemies on the field, overcome obstacles, and win battles all year round. This secret book of formations has now fallen into the hands of Qin Yixian. A few years ago, Qin Yixian used dishonorable means to threaten Shi Jin's life and forced Shi Wei to hand over the secret book, but several pages of it were torn, which means that some battle methods are incomplete.

So her task this time was to find the missing pages. Shi Wei had intentionally torn off these pages, probably because he didn't want him to know what was inside. It was unknown whether these pages would still exist in the world. This task was undoubtedly arduous for her.

After Shi Jin returned to Xiyuan, he asked Zhilu to ask Xu Ruogu to come over to have his clothes measured.

When Shi Jin saw Xu Ruogu, he pulled him aside and smiled, "Gu'er, come and get measured. You've grown a lot taller. It's time to make some new clothes for you."

Hearing this, Xu Ruogu said happily: "Thank you, Sister Jin"

Shi Jin smiled and touched his head, "You don't have to be so polite to your sister."

Seeing this, the maid picked up the measuring tape and showed it to Xu Ruogu, while another maid took notes, and soon the measurement was completed.

When Shi Jin saw Zhilu, he said to the maid who was measuring the ruler, "Measure Zhilu too."

"Yes," the maid said respectfully, and then measured Zhilu again.

Seeing this, Zhilu was overjoyed and said, "Thank you, Miss."

During the measurement, the maid looked at Zhilu with envy in her eyes.

In the past, she thought Zhilu had a miserable life. Following a tyrannical and cruel master, she would never have a good life. Now, she envied Zhilu for following a good master, where she could eat and drink well, unlike her who had nothing in Dongyuan.

When Shi Jin saw that the maid had already taken the measurements, she pointed at the cloth on the table and said, "Use these cloths to make three clothes for me, Gu'er will make three clothes, and Zhilu will make two clothes."

"Okay, if the young lady has no other instructions, we will leave now," asked the leading maid.

"I have nothing to do here, you can go down." Hearing this, the maids retreated one after another.

After the maid left, another maid came over and said, "Miss, Guard Lin is waiting for you in the study. He said he has something important to report."

Shi Jin thought to herself that Lin Yang had been secretly observing the movements in Dongyuan, and now he came to her, probably because he had discovered some clues.

"Okay, I understand." The maid retreated after seeing this.

Then Shi Jin looked at Zhilu and Xu Ruogu and said, "Let's go to the study and listen to what good news Lin Yang has brought."

Then the three of them moved to the study. When Lin Yang saw Shi Jin coming to the study, his eyes lit up. After Shi Jin sat down, he said, "Miss, yesterday I found that the maid next to Aunt Zhao was behaving strangely and secretly buried something in the backyard. Afterwards, I checked and found that she was burying medicine residue. I thought it was strange, so I took the residue out."

Hearing this, Shi Jin seemed to realize that there was something strange about this question. Then Lin Yang took out a medicine bag, opened it and placed it in front of Shi Jin, asking her to check it out.

She picked up the medicine bag and looked at it carefully, her eyes lit up. Wasn't this the medicine that Aunt Zhao drank last time? That time, in order to prevent her from noticing anything, she let Zhilu fall to divert her attention.

She had suspected before that there was something wrong with the medicine Aunt Zhao drank. Now it seems that the maid beside her secretly hid the medicine residue in the backyard. This medicine must be hiding a secret.

Shi Jin stood up quickly, walked to Xu Ruogu, and asked anxiously, "Gu'er, can you take a look at what this medicine is used for?"

Seeing this, Xu Ruogu quickly took the medicine bag and looked at the herbs inside with a serious expression.

After a while, he said, "This medicine contains Trillium, Curcuma, and Pentaxylid... etc. These medicines are blood-activating medicines used to dissolve blood stasis. Generally, women can take it when they have menstrual pain, but they cannot take it for a long time, otherwise it will consume energy and make people weaker and weaker."

Hearing this, Shi Jin's face darkened and he fell into deep thought.

If Aunt Zhao suffered from menstrual cramps and drank this medicine to relieve the pain, there would be nothing wrong with that, but she seemed to drink this medicine frequently, which was rather strange.

Generally, when patients take medicine, doctors will remind them of the dosage. Aunt Zhao should know the side effects of taking too much medicine, but she takes it frequently. This shows that she does it on purpose. What is her purpose? To pretend to be weak?

In Shi Jin's impression, Aunt Zhao was often weak, probably because of the medicine, so why did she pretend to be weak? Or was she trying to hide something by pretending to be weak?

Shi Jin suddenly had an idea, and she immediately asked Xu Ruogu, "Gu'er, does this medicine have any lesser-known uses?"

Seeing Shi Jin asking this, Xu Ruogu's eyebrows twitched, and some memories emerged in his mind. He remembered that he had read the medical book left to him by Old Xu, and there was a record about another use of this medicine.

So he immediately said, "This medicine has another use, it can suppress internal strength, making people look like ordinary people." Xu Ruogu suddenly realized, "Thinking about it this way, when he took her pulse last time, he noticed that she was weak and confused, which should be related to her internal strength."

Everyone present was surprised when they heard this. They didn't expect that Aunt Zhao was so good at hiding her secrets. She looked weak on the surface, but actually knew martial arts. She was willing to take medicine and damage her body to hide the fact that she knew martial arts. It seemed like she had bad intentions.

If Aunt Zhao stole some information from here or did something to them secretly, they would have no idea.

"If Aunt Zhao knew martial arts, then the assassination of the spy earlier would be explained. Aunt Zhao was a spy planted by Xu Wuchen and Qin Yixian. When we caught her accomplice, in order to prevent her identity as a spy from being exposed, she could only save herself by killing her accomplice."

After Shi Jin's analysis, Zhi Lu's heart trembled, and she said worriedly: "Aunt Zhao has ulterior motives. If she stays in the mansion, she will definitely do something to harm the general's mansion. Miss, do you want to tell the general about this and let the general punish her?"

After thinking for a moment, Shi Jin shook his head and said, "I must tell my father about this and ask him to be more cautious, but since her identity has been exposed, I can't punish her."

Zhilu was confused and asked, "Miss, why don't I understand what you are saying?"

"Because if this spy is not Aunt Zhao, it could be someone else. Instead of asking them to send a new spy and add to our troubles, it is better to let Aunt Zhao continue to be the spy. It will be more reassuring to have her under our noses. We can also use her as a counter-espionage plan when necessary, so don't touch her for now."

When Lin Yang heard Shi Jin's explanation, he looked at Shi Jin with a bit of awe in his eyes.

Seeing Shi Jin's clear analysis, Zhi Lu understood it instantly. She looked at Shi Jin with admiration in her eyes and couldn't help but praise her: "Miss, you are really smart and thoughtful."

Shi Jin smiled faintly at Zhilu, and followed her praise, "I agree with what you said, and I don't mind you praising me a few more times," with a playful tone in his voice.

Seeing this, Zhilu smiled helplessly, while Xu Ruogu looked at Shi Jin with a smile on his face and his eyes moving.

As long as Sister Jin is around, life will never be boring.

After a while, Shi Jin told Lin Yang: "Guard Lin, continue to monitor Aunt Zhao's every move."

"Yes," Lin Yang said respectfully.

After the matter was explained clearly, they all left the study.

As night falls, the moon is hazy outside the window and the night is like a thick inkstone, so deep that it cannot be dissolved.

Shi Jin followed the dim light to Shi Wei's study, where Shi Sheng was. She told them both that Aunt Zhao was a spy.

Shi Sheng was very surprised when he heard this, but Shi Wei's reaction seemed indifferent. It was like you had a shocking secret to share with someone, but that person just simply replied, "Oh, is that so?"

Shi Wei didn't seem surprised at all that the person beside him was a spy, which made Shi Jin wonder if he had known about it for a long time.

She thought so and asked so, but Shi Wei told her that he didn't know and was not surprised because he often fought in battles. As a commander, he had to stay calm at all times and not let the enemy notice any clues. Even if he encountered any very tense and important things, he had to remain calm. This was his professional quality.

Shi Jin was skeptical about this statement, but he didn't dwell on it.

In addition, she also told them her idea and reasons for letting Aunt Zhao stay in the mansion for the time being, and they both agreed with her idea.

Aunt Zhao never imagined that her identity, which she had tried so hard to hide, would be discovered so quickly. She would live under the surveillance of others for the rest of her life, and now she was in dire straits.
