Lin Yanyan came to Shuntian Mansion and happened to meet Guan Sheng who was going out.

Lin ...... Zhen Gongzi, Lord Xiao is asking his subordinates to ask for you. ”

"What about others?"

"In the duty room."

Xiao Qian was distracted by the file, and his index finger tapped on the table.

"You're looking for me?" Lin Yanyan came in.

There was a hint of astonishment in Xiao Qian's eyes: "Why did you come so quickly?" ”

Guan Sheng seems to have just left.

"Oh, I happened to be looking for you too, and I met Guan Sheng at the yamen." Lin Yanyan found a chair and sat down.

Xiao Qian snorted lightly and said to himself: "Is this considered a good heart?" ”

Lin Yanyan just wanted to pour himself a cup of tea, but when he heard this, his hand slipped, and the teacup fell over.

Xiao Qian smiled bitterly: He said it so quietly, she could still hear it.

Xiao Qian walked over, took the teacup from her hand, and poured her a glass of water.

Lin Yanyan coughed dryly twice, but he didn't hear the sentence just now: "You say it first, find me something." ”

Xiao Qian said: "Qiu Rong confessed, the poison and the drug were bought from the man who set up a stall in front of the City God Temple to sell dog skin plasters, yesterday was the market, I went to look for it, but I didn't find anyone, but according to the old man who has been setting up a stall there all the year round, on the fifteenth day of last month, there was indeed a man with a black mole under his left face who bought bone skin plasters at a stall there. He remembered that it was because the man had taken his place, and the two had a fight, and they never saw the man again. ”

"So yesterday, I went to ask Qiu Rong again, Qiu Rong said that she went to the City God Temple with Feng Yichen, but she broke up unhappily because there was a small vendor selling jewelry...... The price is the same as the butterfly hosta last time. Qiu Rong had seen a butterfly hosta in Bihan, so he questioned Feng Yichen, Feng Yichen admitted it, and left first in a huff. Qiu Rong couldn't be angry, and it happened that the man who bought the dog skin plaster recommended poison to her, saying that the rat would die if it was licked once, and she hated Bi Han, so she bought it. ”

Lin Yanyan groaned: "If you say so, it is very likely that from the beginning of visiting the City God Temple, Qiu Rong entered someone's carefully set up bureau." ”

"Yes, I think so too, but what is the purpose of this man's murder with a knife? Why does Bihan have to die? So, I checked Bihan's background again. Liujing Pavilion's mother Qi said that Bi Han is the daughter of a criminal official, Bi Han's surname is Zhang, a native of Beijing, I went to check the files of the Criminal Department, and found all the case files of the criminal officials surnamed Zhang. ”

"Did you find it?" Lin Yanyan asked eagerly.

Xiao Qian hooked the corners of his lips and smiled secretly.

If he didn't find it, how could he be embarrassed to invite her?

"Zhang Boqian, the former household department of the two Guangqing officials, four years ago, because he was reported for corruption, he was imprisoned after verification, and on the third day of imprisonment, he committed suicide by hanging himself in prison. Zhang Boqian has only one daughter, named Zhang Biru. The age is the same as Zhang Bihan. That Zhang Boqian likes to play chess, and his chess skills are excellent, and my father once played a game with him. ”

Lin Yanyan frowned: "I committed suicide again, and I died a little strangely." ”

"Yes, only the dead are safest."

"Not necessarily, maybe Zhang Boqian left his hand." Lin Yanyan took out the copied article and map.

"This is what I found from the chessboard, a travelogue and a map, written about Woniu Mountain, and painted on Woniu Mountain, you see, can you see the subtlety."

Xiao Qian was surprised: "It's really mysterious, your intuition is quite scary." ”

"I really didn't have a way, so I asked Fenghua to dismantle the chessboard, and I found out."

Xiao Qian smiled, picked up the article and looked at it carefully, then looked at the map, and the more he looked at it, the tighter his brows tightened: "This is an ordinary travelogue, and there are no marks on the map." ”

"There must be a problem, you think that Bihan studies chess games every day, maybe he is also understanding the secrets, if it is so easy to be discovered, this thing will already fall into the hands of others, you can take a good look."

Xiao Qian thought for a while: "Do you remember the endgame that Bi Han put in when he died?" ”

Lin Yanyan nodded: "Remember!" ”

Xiao Qian put away the article and map: "Let's go, let's go to Master Ji." ”

Master Ji heard Xiao Qian say that he wanted to borrow the chessboard and chess pieces, so he asked people to take them.

"Yan Yan, you put the chess game out."

Lin Yanyan fiddled with the chess pieces while recalling, and said after a while: "It's done." ”

Does this work, though?

Xiao Qian said: "You see that there are a total of three hundred and sixty-one intersections on Go, and this article is only three hundred and sixty-one words. ”

Lin Yanyan's eyes lit up, okay, Xiao Qian's head is really good.

Master Ji was also excited, picked up his pen and prepared to draw a chessboard, filling in the three hundred and sixty-one words.

Lin Yanyan closed his eyes and regarded the three hundred and sixty-one words as the intersection points on the chessboard, and then corresponded to the endgame.

Take out the words where all the sunspots are, no, the words are messy.

and took out all the words where the white children were, but it was still not right.

No, no, no, no......

If Zhang Boqian hides the information in the article and the chess game, it must be concise and to the point.

The map...... It doesn't seem to be of much use!

Xiao Qian is also thinking, what secrets are hidden in this? How can I crack it? He believes that the general direction must be right, but the key point has not been found.

Lin Yanyan's mind flashed: "Xiao Qian, do you know Go?" ”

"I understand a little." Xiao Qian said modestly.

"You point out the 'sealed' characters of all the sunspots."

Xiao Qian obeyed and clicked a few sunspots on the chessboard.

Lin Yanyan closed his eyes and took out the words corresponding to the sunspots. Still not right.

"I want Baizi's 'seal' to be dealt with."

Xiao Qian ordered a few more whites.

This time, Lin Yanyan smiled: "I untied it." ”

The pen in Master Ji's hand was stunned, was there a mistake? He is only halfway through the chessboard, and Lin Yanyan has solved the mystery?

Xiao Qian is also incredible.

"What is it?" The two spoke in unison.

Lin Yanyan paused word by word: "Ya, Han, Yu, Le." ”

Xiao Qian and Master Ji glanced at each other, and said in unison: "The plaque of the household? ”

Master Ji sighed with emotion: "This Zhang Boqian is also a talent, who would have thought of that place?" ”

Xiao Qian nodded in agreement, he couldn't even think of dying!

"Looks like I'm going to have to go find Brother Nine for a cup of tea." Brother Jiu is now in the Treasure Money Lifting Division of the Ministry of Households.

While Lin Yanyan breathed a sigh of relief, he also felt deep regret for Miss Zhang Biru, Zhang Biru was afraid that she had studied this chess game for four years, but she had never been able to understand the mystery, and that map was a disguise.

However, it is also a pity that Zhang Biru didn't find out, otherwise she might have been poisoned a long time ago, and she and Xiao Qian wouldn't have been able to find out.

It is also a coincidence that Zhang Bihan left a move on the verge of death, "sealing", which not only reflects Feng Yichen, but also leaves clues for unraveling the mystery of the chessboard.

Maybe there is providence in the dark! Miss Zhang, you can go with peace of mind, if your father does have grievances, we will avenge you.
