Siheyuan: At the beginning, you can absorb good luck to stay alive.

After Mei Wenhua heard the noise outside, he came to the door and opened it.

Standing outside were Zhou Jianjun and Officer Lu, both of them holding bags in their hands.

After seeing Mei Wenhua open the door, the two handed the bag to Mei Wenhua.

"What kind of wind has brought you here? Come and sit in the house. Really, it's enough as long as people come. Why do you still come with gifts? This is foreign!" Mei Wenhua said, her hands not slow at all, He took the bags handed to them by the two of them.

"It's too embarrassing to come here without a gift, otherwise we would all come empty-handed."

"When I came here, I happened to see someone selling something on the roadside, so I bought it. It's not a rare thing."

Mei Wenhua brought them to the table and put the bag on the table, "You guys came just in time to help in the kitchen. I just stewed the mutton. You can cook the other dishes yourself if you want to eat them!"

"Let me do it, Lao Zhou, you and Xiao Wenhua discuss it!" Officer Lu rolled up his sleeves and walked into the kitchen.

After checking what was in the kitchen, Officer Lu started to take action.

"There are no outsiders, let's talk while cooking!" Zhou Jianjun was embarrassed to be idle, so he followed him to the kitchen to help Officer Lu.

"Little Wenhua, it's like this. The two of us have gone to Hongxing Primary School today to inquire about the book on the Art of War. I also got a copy of Sun Tzu's Art of War, but I didn't find any clues in it myself, so I gave it to him. Professionals are here to handle it.”

Zhou Jianjun briefly explained the situation he had investigated.

"I also asked the teachers in the school to find out. There are two teachers in the elementary school who have books on Sun Tzu's Art of War. Teacher Sun's book has been obtained by Lao Zhou, and the remaining one is in the hands of Yan Bugui in your yard. There, but it seems he took it to school and lost it!"

"You are very efficient! But you are worse than me!" Mei Wenhua said calmly.

"What's worse than you? Have you asked your sister to find out?" Zhou Jianjun looked at Mei Wenhua and asked.

"Little Mei Lan hasn't finished school yet? What can he know?" Officer Lu said while washing vegetables.

"That's right, Xiao Meilan hasn't come home yet!" Zhou Jianjun nodded, "The two of us came here just to see how much you know about Yan Bugui, and to know whether his book was really lost or hidden by him. Woke up?"

"I don't know much about him, but his book must have been lost!" Mei Wenhua said firmly.

"Why so sure?"

"Because my sister picked it up!" Mei Wenhua reached into his clothes, took out a black book, and threw it to Zhou Jianjun.

Zhou Jianjun quickly caught it with both hands, "Don't throw it away. There may be clues to the treasure inside! The kitchen is on fire. If it falls into the fire and burns, the damage will be great."

"Little Wenhua, that's amazing! Why are you so sure? It turns out the book is already in your hands!"

"Yesterday, my sister was on duty and picked it up next to the garbage pool. She thought it was someone else who didn't want it, but she didn't expect that it was Yan Bugui who threw it away!"

"Xiao Meilan is really lucky. She picked up this book, which saved us a lot of trouble. If we can find the treasure, she will have a share of the credit." Zhou Jianjun began to carefully examine Sun Tzu's Art of War.

Officer Lu also wanted to put down the food in his hand and watch it together, but was stopped by Mei Wenhua.

"You two don't want me to cook alone, do you? I can't do it, and even if I do, I'm worried that you won't be able to eat it!"

"Okay, okay, it seems I still have to take action! Old Zhou, please be serious and try to find the clues!"

"I know, you cook well, I'll take a look under the light!" Zhou Jianjun came to the light with the book in his arms.

Half an hour later, Officer Lu had already prepared the dishes, and Zhou Jianjun basically read through Sun Tzu's Art of War, but found no clues.

"Nothing was found! I don't know if the clues to the treasure are recorded in this art of war book!" Zhou Jianjun rubbed his eyes.

"There are only two teachers from Hongxing Primary School who have Sun Tzu's Art of War. Check Teacher Sun's book. There are no clues. Isn't this one also missing?" Officer Lu put the dishes on the dining table.

"Nothing was found. I have written down all the words marked above and found no clues related to the treasure!" Zhou Jianjun shook his head.

"Could it be written with something special that can't be seen by ordinary methods?" Mei Wenhua guessed.

Zhou Jianjun was thoughtful when he heard Mei Wenhua's words. He walked into the kitchen with Sun Tzu's Art of War and put the book on the fire to bake.

This time, I really discovered something.

After the black cover was roasted by the fire, it started to change color, and the color was getting lighter in some places.

After a while, a map that was not very obvious appeared on the black cover.

"My dear, this seems to be a map, right? The enemy is so cunning that he actually hid the map on the black cover." Mei Wenhua sighed.

"This is indeed very safe. With black as the background color, it is indeed harder to find!" Zhou Jianjun nodded.

"The key is that even if they know the method, many people think it's recorded in the book and won't check the cover carefully! Even if we roast it over fire now, we won't be able to tell it without looking carefully!"

"Iwato Shota is awesome! He actually told us that it was a text clue. It seems that he woke up from my hypnosis on his own at that time. No wonder he fell into a coma!" Mei Wenhua remembered the time when he interrogated Iwato Shota Case.

It seems that I cannot rely entirely on hypnosis in the future. It is still possible for people with special training to wake up from hypnosis on their own.

"Are you not good at it? Why do I feel like you are not good at your studies?" Officer Lu said deliberately.

"How about I try it on you?" Mei Wenhua was eager to try.

Officer Lu was so frightened that he quickly walked away, not daring to get close to Mei Wenhua, "I'm just kidding, it's better not to do it, besides, we are going to eat soon!"

Mei Wenhua looked at the dishes that had been put on the table and came to the door to take a look. Her sister and mother came back a little late today. If they didn't come back, the cooked dishes would be cold.

As soon as Mei Wenhua stretched out her head and looked out, she saw her sister and mother in the yard.

"Brother, how did you know we were back?" My sister waved to Mei Wenhua.

"Uncle Zhou and Uncle Lu came to our house. We have prepared the food and are waiting for you to come back for dinner. I am about to pick you up! You will be a little late today."

"We didn't ride bicycles today, so of course we have to walk slower!"

When Zhou Jianjun and Officer Lu inside the room heard the noise, they quickly put away Sun Tzu's Art of War and came to the door together.

"Comrade Mei, come back, we have the shamelessness to come to your house for dinner today!"

"You're welcome at any time, what are you talking about?" Mei's mother smiled, and she guessed that these two people were here to see Mei Wenhua.

If the two of them have nothing to do, they usually won't come to the courtyard.

After Mei's mother took her sister to wash her hands, she started to eat.

"Sister, which dish do you think is the most delicious?"

"I guess you stewed the mutton, brother, and Uncle Lu stir-fried the other dishes! They are all delicious!" said my sister as she ate.

"Wow, Xiao Meilan is so awesome! She guessed everything right!" Officer Lu gave his sister a thumbs up.

"I have eaten all the dishes you cooked. Once I eat them, I will know who cooked them! This is not difficult at all!" My sister was a little embarrassed by the praise.

Everyone chatted while eating, and my sister became the topic of conversation.

After eating, Zhou Jianjun took Officer Lu back. The two of them had to go back and work overtime to determine the location of the treasure.

Mei Wenhua sent them out, and when she came back, she found that Mei's mother and her younger sister were cleaning up and washing the dishes.
