Banniang received an urgent top-secret document from Xiao Lei, and the top-secret level was the highest level.

Banniang looked at the letter sealed with fire paint, and wondered, shouldn't the top-secret document be given to Xiaoyan?

Look at the four words on the envelope again, yes, it was for herself, so Banniang, who was full of doubts, opened the top-secret letter.

At first glance, Banniang was even more confused.

Xiao Lei only said in the letter that Pan Roll found him in the army and saw red as gray, and then Xiao Lei said, I really didn't expect that there are people in the world who see things differently from everyone else, but God is fair, maybe these people will be better than ordinary people in other aspects. Xiao Lei said that she plans to allocate part of Liuhe's income to study this issue.

In the end, Xiao Lei told Banniang that Fu'er gave Rabbit another self-portrait, still with big eyes, and laughed at Fu'er for being so persistent.

Then I wish Banniang and Little Eyes all the best, and it's over...

Ba Niang...

Banniang, who closed her eyes and pondered for a while, flipped the page over and over for a long time, but she didn't see why.

This letter said two things, one is that Xiao Lei heard that he has color blindness, he thinks it is very strange, and he is ready to study it, and the other is to tell Fu'er about the state by the way...

Is this content sent back with a top secret rating?

Banniang turned the letter paper over and over, from top to bottom, from left to right, from positive to negative, carefully and carefully, and looked at it seriously for a long time, and did not find any problems, and then looked at the sentence from left to right, from right to left, from bottom to top, obliquely... Still haven't found out.

Banniang used her brain seriously, thinking about it, thinking about it: Why do you want to mention Fu'er, could it be that Xiao Lei and Fu'er agreed on some code words? Banniang felt that this might be more likely, so she sent someone to inform Fu'er that she would not go anywhere after school, go home to report first, and by the way, she also sent someone to tell Xiao Yan that she had received Xiao Lei's letter.

And after the little eye explained that the secret guard buried all kinds of auspicious rui inside and outside Bianjing City, he received a report from the palace people, and happily went home from work, well, he replied to Xiao Lei in the evening, asking her to get ready, she was going to Mount Tai in the second half of the year, and she must plan her itinerary.

So, Xiaoyan and Fu'er met at the gate of Banniang's courtyard.

The little eyes looked at Fu'er with an unhappy face, and said with a smile, "What's the matter?

Fu'er said sullenly: "Bao Zheng is a complainant!"

The little eyes didn't care, "You are allowed to bully people, and no one is allowed to complain to Mr."

"A-Niang is looking for me!" Fu'er was indignant and sued her parents directly, it was too much!

Little Eyes smiled, "It's okay, it's me." By the way, why did you bully Bao Zheng?"

Fu'er secretly hid Bao Zheng's homework, so Bao Zheng was punished by Mr., but a day later, Bao Zheng actually relied on various clues to ask Fu'er for an explanation.

Fu'er sighed, she really isn't the material for a thief..."Just kidding..."

Bao Zheng, who was already black-faced, turned even darker..."Unrepentant!" flicked his sleeves and left, he didn't look at Fu'er today, and his temper was very big.

"I must have complained to A-Niang!" Fu'er said sullenly, because under normal circumstances, Banniang would not send someone to inform Fu'er and hurry home.

In Fu'er's heart, Banniang can sometimes be regarded as a strict mother, but Xiaoyan has always been a loving father and a loving father who dotes on his children!

"This Bao Zheng, maybe he will be a master of solving cases in the future, he is bold and big, and it is not bad to be a royal history, cultivate and cultivate well, and maybe he can become a generation of famous ministers. The little eyes smiled and comforted Fu'er, "The days when you were bullied by him are still ahead, haha! Now you can bully him a few times, just hurry up and bully more..."

Fu'er was speechless, "Why should I let him be the prime minister..."

"No, why can the prime minister bully me? I specialize in bullying the prime minister, okay..."Fu'er was very angry, rolled her eyes at the little eye, don't treat others with yourself...

Xiaoyan shook his head slightly, "You'll know in the future, okay, don't keep a straight face, go, see your aunt go, Xiao Lei has a letter." ”

Xiaolei sent a letter? Fu'er was happy, hehe, the rabbit's letter should have arrived too.

So Banniang saw the smiling father and son.

After a while, Xiaoyan and Fu'er also became serious, and even Fu'er didn't have time to blush Xiaolei to hit his little report.

The three of them looked at the letter again and again, swept it on the flames, and wanted to soak it in the water, but they were afraid that it would be damaged...

In the end, Little Eye called the Dark Guard and asked the Dark Guard, how did the top secret information be transmitted inside?

The Dark Guard offered a small porcelain vase and dipped a pen in the potion and smeared it on the paper, revealing the hidden message...

Banniang doesn't admire the secret guard, this involves chemistry...

But this potion is useless for Xiao Lei's secret letter...

Helpless, Little Eyes could only send the secret guard to send a letter to Xiao Lei, telling Xiao Lei that he didn't understand, he didn't understand, the secret guard who sent the letter was reliable, and he could let the dark guard come back with a message.

After the arrangement, Little Eyes and Fu'er began to be surprised, it was strange that someone saw a different color than ordinary people...

Banniang...", you can let the Taiyi good students study and study. "I don't know what Chinese medicine is...

"By the way, I think that potion is quite interesting, the person who does this should be very powerful, right?" Banniang thought that maybe she could start with the potion and slowly develop technology...

"It must have been passed down from generation to generation, the secret recipe. "Little eyes don't have any forward-looking awareness at all.

But seeing that Banniang was so interested, Xiao Yan called the head of the secret guard again and asked the source of this potion, and sure enough, it was the secret recipe of the secret guard organization, which was strictly kept secret, and there were only a few people who knew the secret recipe, and as for where the head of the secret guard came from, I didn't know, anyway, when he took over, everyone would know this secret recipe.

"We can't just know what it is, but we don't know why", after the leader of the dark guard left, Banniang said: "Why can these things be put together to produce this effect? If we know the reason, can we still make other things? The firearms workshop has not made much progress so far, mainly because we only know the fur, and we don't know why he is like this, so we can't improve it, so the cost is so great..."

"The craftsmen don't understand..."The little eye sighed as soon as he heard the firearms workshop, it really cost too much, this thing is really powerful, but the army can't popularize it, so people are not in a hurry!

"The craftsman doesn't understand, but the reader probably does, right?" Banniang prompted.

"Which scholar would come to ponder this?" smiled the little eye, "even if there is, maybe one or two will come out in a thousand years..."

"Then you can also open an engineering department, the imperial examination has a Ming Jing department, there is a Jinshi department, so why can't you open an engineering department? There is also an agricultural department, a water conservancy department?" Banniang smiled: "If the examination score is a little more detailed, you may be able to find many talents..."

"This is not easy to do..."The little eyes were stunned for a long time, shaking their heads, the court is still not allowed to make a noise...

Fu'er was thoughtful...

"What is easy for you to do?" Banniang looked at the little eyes and smiled...

"Let me think..."

Fu'er...
