Nangong Jin was also very surprised at this scene at the moment, only the sunlight and candlelight could reveal the hidden words, how did this happen?

"Brother? What's going on here? Song Jiayao was puzzled, as far as she knew the home remedies, either soak them in water or soak them in special medicines, and the hidden words inside could be clearly revealed, and Song Anguo refreshed their cognition with a new method today.

"Uh......" Song Anguo scratched his ears, looking distressed, he didn't know how to explain to them the refraction of light, reflection and the like, as well as the overlap of ray frequencies and so on.

"Actually, it's not the process that matters, it's the result that counts." Song Anguo changed the topic and said, if he continues to be entangled like this, he really can't bear it.

"I'm just a blind cat and a dead mouse." Song Anguo said embarrassedly, he heard Song Jiayao say that Nangong Jin couldn't decipher it even after exhausting the soil method, which reflected from the side that the ancient method was not suitable for breaking this blank paper.

In this case, he can try modern methods, and there are many types of modern methods, and he didn't expect that he would choose one of them to try and successfully decipher it.

Luck plays a big part in this......

"That's right, master, you've wasted a lot of time trying to decipher the contents of this blank paper, so let's quickly read the contents inside." Zheng Dai relieved the siege.

Song Jiayao glanced at Song Anguo suspiciously, and then turned her head to look at Zheng Dai, aren't these two people at odds? Why did you suddenly match the plate?

However, it is really not appropriate to delve into the process of decipherment, after all, the same method may only be used once, and the next time you encounter something similar, you may not be able to continue to use this method to successfully decipher.

"That's right, Nangong, let's read the content first."

"If the news recorded in this is really important, then so many days have passed, and there will be more variables." Song Jiayao agreed.

Song Anguo wiped the cold sweat that kept breaking out on his forehead, if his sister and Nangong Jinruo continued to ask, he really didn't know how to answer.

Nangong Jin nodded, stayed up and read it carefully, and it was really as Song Anguo had guessed before, only one sentence was written.

That is, "after entering the territory of the Da'an Dynasty, assassinate the princess of the Plains Kingdom and blame the Da'an Dynasty." ”

“！！” After reading it, the four of them also felt shocked at the moment, the monarch of the Plains Country was so vicious, although this princess was not from the same mother as him, but she was also a brother and sister, and she could actually kill her! !

"Nangong, remember correctly, it seems that half a month has passed since the day you and Shengshangna received the news that the princess of the Plains Kingdom came to get married!!" Song Anguo roughly calculated with his fingers, and said with a solemn face.

Nangong Jin frowned lightly and nodded, the princess of the Plains Country has long been on the way to the Da'an Dynasty, and she should be about to enter the border of the Da'an Dynasty, if this secret letter is true, then these people should start to do it after this princess enters the border of the Plains Kingdom!!

"You go back first, leave the rest to me, and I will go to the palace to discuss with the saint." Nangong Jin said solemnly, this matter cannot be delayed!!

"Nangong, I'll go with you." Song Jiayao said uneasily, Nangong Jin's face was very bad, and she was really worried that he would collapse at any time.

"Hey...... I'll go too. Song Anguo said scoundrelly, Song Jiayao volunteered to catch up, how could he hide here and wait to be killed.

Zheng Dai waved her hand, her identity couldn't enter the palace, and she wouldn't go to join in the fun this time.

"Song Anguo, what do you think?" Nangong Jin said with a solemn face.

"How can you see it, this is a kind of revenge of Chiguoguo, coming at you." Song Anguo said in the air, and casually took an apple on the table in the sedan chair and bit it lightly.

"......" Song Jiayao felt that she was about to kneel to him, and Song Anguo was really right to the point.

"......" Nangong Jin wanted to slap Song Anguo to death at the moment, can this person speak well?

"Anyway...... If you can't save this princess, the whole Da'an Dynasty will take the blame and give him an explanation; As for saving this princess, then she will come to marry, and she will find the most noble person in our Da'an Dynasty to marry, and this candidate, think about it, you have to be. Song Anguo said with a smile.

"......" Nangong Jin was so angry that smoke was rising above his head, couldn't Song Anguo not fall off the stone?

"Ahem, ahem...... Brother, then make plans then, now we give priority to the safety of the princess of the Plains Country, and we can't let the Plains Country, which has always been eyeing us, find an excuse to attack it. Song Jiayao said seriously.

Song Anguo glanced at Song Jiayao sadly, his sister has not yet married Nangong Jin, and she has begun to think about him everywhere, which really fulfills the sentence "one is willing to fight and one is willing to suffer".

"Let's talk about it when we enter the palace, after all, there are many people." Song Anguo reminded, and Nangong Jin's eyes suddenly became sharp.

After a while, Zhao Si's voice came: "Master Hou, those who are following are completely solved." ”

"Yes." Nangong Jin replied expressionlessly, it seems that the people of this Yin Mansion have already hidden in every corner of Da'an Dynasty Kyoto, and they are probably responsible for the assassination of the princess.

"The situation is a bit beyond my expectations, relying only on the ritual department that can only embroider fists, the princess is afraid that she will die before she can successfully welcome her in." Nangong Jin said with a gloomy face.

"You actually sent Lin An and his family to be in charge of such an important matter?" Song Jiayao was surprised, in her opinion, it was much better to send someone else to be responsible for entertaining the princess of the Plains Country than to be in charge of entertaining Lin An's family.

"Because their family makes me feel disgusting!!" Nangong Jin said truthfully.

Song Jiayao's heart warmed, this person is afraid that he is angry with himself, after all, Lin An had stalked her at the beginning, and even now, he still thinks about himself.

"If you teach them well, just teach them to death." Song Jiayao said with a smile, she never showed mercy to her subordinates when dealing with enemies, especially a first-class scumbag like Lin An.

Song Anguo raised his eyebrows, although he didn't say anything, Song Jiayao knew that he was quite satisfied with Nangong Jin's approach, but his brother didn't like to express it.

"Master Hou, I've arrived at the palace gate." Zhao Si reminded.

Nangong Jin took the lead in getting down from the sedan chair, and bent down slightly to bow her head, and gentlemanly stretched out her hand to wait for Song Jiayao below.

Originally, Song Jiayao planned to get off the sedan chair behind Nangong Jin, but she didn't expect to be stopped by Song Anguo, Song Jiayao looked at him puzzled, not knowing what gourd he was selling.

Someone put his hand in Nangong Jin's hand, Nangong Jin thought it was Song Jiayao, and was about to drag her into his arms, but he was so frightened by the sudden sound from above that he hurriedly let go.

"Oh, Master Hou, you are so bad, the slave family doesn't have that quirk." Song Anguo made an orchid and said shyly, and the unknown palace gatekeeper was desperately covering their mouths at the moment to prevent laughter from leaking out.

Nangong Jin immediately petrified in place, then turned his head to the side and vomited wildly, he would definitely have nightmares from today onwards!!

"Brother!!" Song Jiayao said helplessly, Song Anguo is too bad, doesn't this mean to disgust Nangong, a man as tough as steel!!

Song Anguo tilted his head and whistled into the air.

"Song Anguo, you wait for me." As he passed by, Nangong Jin threatened.

This revenge is not a gentleman!!

After the guards guarding the palace gate simply checked Nangong Jin's identity token, they opened the palace gate and greeted him respectfully, after all, who Nangong Jin didn't know in the entire Da'an Dynasty?

His face itself is a walking identification.

Zhao Yue, who was still listening to the sound of the piano at Song Jiarou's place, heard his father-in-law tell Nangong Jin that he had entered the palace, and then gently hugged Song Jiarou and turned around and left for the imperial study.

"Nangong, why don't I go to the third sister and talk to Concubine Rou?" Song Jiayao suggested that several of them were here to discuss state affairs, and it would be more appropriate for her as a woman to avoid it.

"No, I don't."

"You don't have to raise eyebrows, why are you here now?" Nangong Jin joked.

Song Anguo directly inserted himself between the two of them, cutting off the two of them's fancy show of affection.

As soon as Zhao Yue stepped into the imperial study, he felt that the temperature in it was very low, and it was estimated that it was comparable to the ice cellar, and as soon as he looked up, he saw Song Anguo and Nangong Jin confronting each other, and Song Jiayao was in a dilemma at the moment.

Well...... What a wonderful and unbeatable love triangle.

"Ahem...... Zhao Yue coughed, reminding the two of them to stop in moderation.

"Knock on my emperor, long live my emperor, long live, long live." Song Anguo said respectfully to Song Jiayao, while Nangong Jin only bent down and bowed.

"Song Aiqing, Ping'an Hou, what are you going to see me in private when you enter the palace?" Zhao Yue said with a serious face.

"Returning to the Holy Shrine is for the princess of the Plains Country, as well as the matter of the imperial merchant Tan Perseverance." Nangong Jin said truthfully, he believed that Tan Jianren's matter must have been learned from other ministers.

"Tan Jianren, you really need to give me a good explanation, the entire Tan Mansion was bloodbathed overnight, and Tan Jianren's whereabouts are unknown now." Zhao Yue was not angry and arrogant, and asked.

"Tan Jian is stoic that he has been thrown out of the back mountain by my subordinates to fend for himself, and now rush over, it is estimated that he can collect his body."

"As for the bloodbath in the Tan Mansion, I sent my subordinates to arrange it, in order to make ordinary people mistakenly think that Tan Jian had offended the martial arts people and was retaliated against." Nangong Jin said truthfully.

Zhao Yue was not displeased after hearing this, after all, Nangong Jin indirectly solved a big trouble for him, but those old foxes in the court who have always been unhappy with Nangong Jin's dominance are afraid that they will embarrass him everywhere.

"You are also too abusive of lynching, let the marble side, Jing Zhaoyun's side, and the criminal department deal with each other." Zhao Yue said helplessly.

"It's very simple, let them put the blame on me, I see those old foxes who dare to question me face to face!!" Nangong Jin said domineeringly, he was really not afraid of trouble to find him.
