"who are they?"
"Qin Tian Jian on the Si Tian Tower."
The tallest building in the imperial city is not the Jinluan Hall, but the Sitian Tower in the west of the imperial city. Sitian Tower has seven floors and stands like a pagoda in the imperial city.
Qin Tian Jian works in the Sitian Tower, and the top floor is where Qin Tian Jian uses it to observe astronomical phenomena.
Qin Nan continued: "The Sitian Tower is not only the tallest building in the imperial city, but it also overlooks the entire capital. Guangdu Temple is right on the edge of the imperial city, so you can naturally have a clear view."
"The duty of the Qintian Supervisor is to observe changes in the celestial phenomena, so there are people on duty in the Sky Patrol Pavilion on the seventh floor all year round, and the personnel on duty are rotated in a fixed order. In this way, people outside the palace only need to do detailed work. At that time, by lighting purple smoke at Guangdu Temple, the message could be easily conveyed to the palace."
Zhou Jin was dumbfounded and couldn't help but exhale softly: "So when the purple smoke rose, the person on duty at the Xantian Pavilion of Sitian Tower was probably Pei Xuan's person."
Qin Nan nodded slightly, but then said: "However, this is just my guess. There is no real evidence, and it may not be able to convict this person."
"It doesn't matter." Zhou Jin's expression finally became relaxed and happy: "Now that they have exposed their flaws, I will send secret guards to investigate secretly. I believe that this time I will be able to catch all the evil spirits lurking in the palace."
After finishing speaking, Zhou Jin looked at Su Shi in confusion, because according to Qin Nan, when he mentioned the purple smoke in Guangdu Temple, Su Shi had already thought of spies lurking in Qintian Prison, but the strange thing was that at that time he Didn't remind myself.
"Why?"
This question is not easy to answer because Su Shi cannot tell Zhou Jin his true inner thoughts.
But this question has to be answered.
So Su Shi had no choice but to bite the bullet and explain: "In addition to not having any real evidence, I'm also worried that I might alert the enemy."
"Snatch the enemy?"
Su Shi pondered: "Since this person has been lurking in the palace for many years and has never aroused anyone's suspicion, it shows that he is an extremely cautious person. Any slightest sign of trouble may make him suspicious."
Then he looked directly at Zhou Jin and sighed: "Your Highness Princess, you should still remember You Gui. These people are so deeply bewitched by Pei Xun that they would rather commit suicide than reveal any secret. If this person is like You Gui, I will I’m worried that if I become more hands-on, I’ll get nothing in the basket.”
Zhou Jin still couldn't understand and asked: "Why?"
"The spy in Qintian Prison should be just a contact person to deliver information, not the executor of the plan. If the spy is caught rashly, the rest of the people lurking in the palace are likely to lie dormant, waiting for the opportunity. In this way, It’s more dangerous for these people to come.”
"Can't we catch the secretaries of Qin Tianjian and interrogate them strictly, and then follow the clues and catch them all in one go?"
"First of all, we have no real evidence, and there is no legal basis for arresting people." Su Shi said: "Secondly, even if we arrest this person, even if he is tortured, he may not be able to do it. And most likely, this person may not even know that he is To whom did the information go.”
As for what Su Shi said about arresting people without legal basis, Zhou Jin naturally couldn't understand it, so she ignored it. She just said coldly: "I don't believe that this person's bones are so hard that he can survive in the hands of a secret guard." Silent."
But after the angry words, Zhou Jin was most worried about the third reason mentioned by Su Shi.
"Why do you think this spy doesn't know who he's passing the information to?"
"Have you not noticed that whether it is You Gui's use of carrier pigeons or Guangdu Temple's smoke communication, these methods are used to transmit information without the two parties having to meet. Therefore, even if the person transmitting the information is exposed, the message can be transmitted to the maximum extent Keep other people safe.”
"So I believe they should use this method to deliver news in the palace."
Zhou Jin looked at Su Shi blankly: "According to what the young master said, even if we know who is the spy in Qintian Prison, it will not have any impact on Pei Xun's plan?"
"So we have to wait."
"When?"
"When Pei Xun's plan starts to be implemented." Su Shi said slowly: "The so-called arrow is on the string and has to be fired. As long as Pei Xun's plan starts to be implemented, it will be impossible to stop. If we take action at this time, not only will we be attacked Disrupting their rhythm is more likely to cause them to make mistakes and make mistakes in the execution of the plan.”
Zhou Jin naturally obeyed Su Shi's words. At this time, he took it to heart and said with a smile: "No wonder you asked if anything special happened in the palace as soon as you saw me. You just wanted to know if Pei Xun's plan had been implemented. .”
Then her eyes dimmed: "But by the time I left the palace, there was no unusual news in the palace. Presumably they haven't started to implement the plan yet."
Su Shi kept shaking his head: "No, Pei Xuan's plan has already been implemented, but it has not attracted anyone's attention yet."
"Why do you think so?"
Su Shi hesitated for a moment and said slowly: "Using smoke to communicate has both advantages and disadvantages. The disadvantage is that it cannot express complex meanings and can only convey very simple instructions. I believe that when the purple smoke rises, it means Plans have already started to be implemented.”
As soon as he heard that Pei Xun's plan had begun to be implemented, Zhou Jin was immediately confused and couldn't help but asked in a trembling voice: "Then what should we do now?"
"You go back to the palace first and find the spies in Qintian Prison." Su Shi muttered: "As for whether to secretly track or arrest him, leave it to the secret guards. I believe they have more experience."
Zhou Jin knew that Pei Xun's plan was related to his father's life and death. He couldn't stay any longer at this moment and was about to drive back to the palace.
Su Shi hurriedly asked: "Have you found out who was behind the Chenxiang Hall incident?"
Although Zhou Jin was already flustered at this time, he still calmed down after hearing Su Shi's question and said: "The secret guard is still investigating, and the person behind the scenes has not been found yet. But early this morning, Hongsi Fang lucked out. When Che Yinzi left the city, the secret guards followed him."
"Only one car?" Su Shi frowned involuntarily.
Zhou Jin said with certainty: "There is only one car."
Su Shi stopped talking and seemed to be deep in thought. Zhou Jin was worried about his father, so he gave a slight signal to Qin Nan and Chen Xiaolan, hurriedly walked out of the study and returned to the palace.
Qin Nan didn't speak since then. It wasn't until Zhou Jin left that she looked at Su Shi thoughtfully.
Chen Xiaolan didn't have anything important to do when she came here. She just heard that the ban was lifted in the General's Mansion, so she was so excited that she hurriedly came to the General's Mansion. At this time, seeing that Her Royal Highness the Princess had left, it seemed a bit awkward to be here alone, and I also had the intention of leaving, so I got up to say goodbye.
Su Shi suddenly said at this time: "Wait a minute, there is something I want to ask you."
