Xiao Changyun smiled at everyone, not cramped at all, she carefully studied the secret letter for a moment, and then put it on the tip of her nose and sniffed it gently, revealing a clear expression.

"Do you have a clue?" Huo Qing couldn't wait to ask.

Xiao Changyun raised his eyes and said solemnly: "Return to the marshal, return to the prince, return to the generals, although the ink on this letter is dry, it can be printed with force, and it is still attached, which means that the writing time of this letter is not long, and it should be written within three days."

The ink used on the letter has an elegant and light aroma, with a light pine smoke taste, and the color of the pen is black, firm and bright, and it is not faint when it enters the paper, and it is the best ink and lake paper. Perhaps, the marshal can start to investigate from these aspects. ”

Xiao Changyun said that, and all the generals were stunned.

It wasn't until Ouyang You carefully identified the letter according to Xiao Changyun's prompt that he sighed: "What Xuanye Gongzi said is extremely true! The letter should have been written for no more than three days, and the things used for it were indeed lake paper and ink. ”

Huo Qing is also a child of the clan, of course he understands the preciousness of lake paper and Hui ink, and his eyes immediately lit up with excitement: "Lake paper and Hui ink are so precious, we don't have these things in our camp, through these clues, we will definitely be able to find the origin of this letter." ”

As soon as Huo Qing's voice fell, everyone's eyes looking at Xiao Changyun were faintly bright.

Earlier, after Genye's actions in the Governor's Mansion, they had already learned that he was a talent with both medical and poisonous essences, but now it seems that he is proficient in more than the art of healing poisons.

This kid is a genius!

"Ouyang." Xiao Nanjin suddenly spoke, her tone was sharp and strict, "This matter will be handed over to you and Song Qi to investigate together, and you must find it out clearly." ”

"The lowly (last general) commands!"

"Meng Tuo, Huo Qing."

"The last general!"

"You will lead 5,000 elite soldiers, immediately set out from the village to the north of Shanhaiguan, and be sure to bring the deputy marshal back safe and sound!"

"The last general commands!"

Meng Tuo and Huo Qing got up, lifted their cloaks and wanted to walk out quickly, when suddenly a figure stopped in front of them.

"Two generals, can the kid want to go with the two generals?"

"You want to go too?" Huo Qing instinctively wanted to refuse, but when he remembered that this kid was really a little quick, and he also knew medical skills and poison techniques, maybe he could play a role at a critical moment, so he looked at Xiao Nanjin with a soliciting gaze.

Xiao Nanjin's starry eyes widened, and she was about to deny Xiao Changyun's suggestion, after all, she was a powerless little girl, what could she do when she went to the battlefield? It's just a matter of danger!

However, before Xiao Nanjin could speak, Bai Yuan smiled lightly: "This king agrees, but this king wants to go with you." ”

Xiao Changyun's eyebrows lit up, as long as she could go, she would agree to Bai Yuan's conditions.

"Thank you, Lord Wang!"

Xiao Nanjin was so anxious that she blew her beard and glared at her, hey, hey, what qualifications do you have to pass him as a father to "agree"?!

He hasn't opened his mouth yet, has he?!

But Xiao Changyun is now Bai Yuan's military doctor, and he, Xiao Nanjin, is even more "wounded" at this time, so he can't go to the battlefield regardless of his injuries, right?

Damn it!

Knowing this, he wouldn't agree to the stinky girl's plan.

Now it's okay, everyone has something to do, but he, Xiao Nanjin, has been reduced to a "half waste", and can only sit and wait and wait for the result...... This really made him scratch his heart and lungs, and he was anxious!
