"Yes." Liu Sili also said, "When the drum sounds, everyone knows that Wanglou is sending a message. Will the traitors and the people behind the scenes of Dali Temple still be fooled?"

Pei Shaoqing smiled slightly and said, "Then don't beat the drum."

"Don't beat the drum?" Wei Chengqing said, "How can I send a message if I don't beat the drum?"

"There are many ways to send a message, not just beating a drum," Pei Shaoqing said.

Di Renjie said: "It seems that Pei Sicheng already has a decision in his mind, so why not talk about it?"

"Use lanterns." Pei Shaoqing said, "It's only been a few days since the Spring Festival. There must be a lot of lantern shops in the east and west markets and even the various lifangs."

"You can buy three-color lanterns with red, yellow and green in large quantities."

While talking, Pei Shaoqing walked to Di Renjie's desk, picked up the brush and drew it.

"You see, if you string a group of three-color lanterns together, there can be six different combinations."

"From top down, they are red, green, red, yellow, green, green, yellow, yellow, yellow, red, yellow, yellow, green, yellow, green, and yellow."

"If two groups of three-color lanterns are placed side by side, there can be thirty-six different combinations. If three groups of three-color lanterns are placed side by side, there are 216 different combinations."

Speaking of this, he asked Di Renjie again: "Di Temple is the main hall, how many viewing buildings are there in Chang'an?"

Di Renjie said without hesitation: "There are 180 viewing buildings in Chang'an City."

"Enough." Pei Shaoqing said, "Enough to allocate a lantern combination to each building, and there is still plenty of money."

"Then a separate lantern is hung in four directions, up, down, left and right of these three groups of lanterns, north of the top, south of the bottom, west of the left, east of the right, so that accurate direction transmission can be achieved between the towers."

"For example, when you arrive at the east of Yongxingfang, you will hang a combination of lanterns from Yongxingfang, and then hang a big red lantern on the right side of the three groups of lanterns, which will accurately convey the information to the next watchtower."

After a pause, Pei Shaoqing smiled and said, "This matter is not complicated to operate. You just need to make a 'clear' comparison chart and distribute it to each building, and then you can do it with a little explanation."

"Genius!" Liu Sili couldn't help but praise, "This is really a genius' idea!"

Di Renjie was also moved and said, "After this case, I will definitely report to the Queen of Heaven to ask for merit for you."

Liu Sili immediately said, "Di Si is just not forgetting to sign for me. I also want to jointly write a letter to ask for me for me. This innovation will be of great benefit to the public security of Chang'an City."

Wei Chengqing said: "I want to sign too."

Pei Shaoqing said: "I've been too rewarded, so I'm ashamed of being a magistrate."

"But there is another problem." Di Renjie said again, "The principles of lantern transmission and drum sound transmission are actually similar, and they can only convey directional information."

"If it is a thief who commits the crime, it is easy for the Marquis of Wu on the tower to be able to confirm it."

"But how should the insider who went out of Dali Temple to report the news? Lantern transmission could not describe the person's appearance."

"There are actually still ways." Pei Shaoqing said, "You can change the three-color lanterns to four or even five colors, and the number of groups can also be increased to four or even five groups."

"This can completely realize the complex sentencing of the Hostel."

"It's probably not difficult to convey the appearance of the thief."

"But it's not possible now, because the time is too tight."

"It takes time for Wuhou to learn such a complicated messaging."

"Hey yes." Liu Sili, "What should I do?"

"Actually, it's easy to deal with." Di Renjie said with a moment of contemplation, "It's enough to ensure that there is only one inner supporter on the street."

"How is this possible..." Liu Sili suddenly reacted before he finished speaking and said, "Are you saying that you should wait until the evening drum sounds and the door closes before the wind will be released?"

"But it was probably dark at that time."

"Wuhou in the building can't see where he looks?"

"No." Pei Shaoqing smiled slightly and said, "As long as we do our best, our inner servants will go to report to the people behind the scenes at all costs."

"If I were him,"

"It will not only set up a torch, but also ride a fast horse."

"I will even show the waist sign of Dali Temple to drink Wuhou who has retired from the patrol."

"Just just want to pass the message to the person behind the scenes in the shortest time."

Liu Sili said in surprise: "But if this is the case, won't he be exposed?"

Di Renjie said in a deep voice: "It is destined to be exposed when he takes the risk of sneaking out of Dali Temple to report the people behind the scenes, but he will still choose to report the news."

Pei Shaoqing continued: "Because the consequences of Zhang Sanhui's speech are more serious than his exposure!"

"Oh, I understand!" Liu Sili and Wei Chengqing suddenly said, "The two evils are the least."

Pei Shaoqing said again: "Di Sicheng, it's not appropriate to go to buy lanterns without delay, so hurry up and ask Wuhou from various lifangs to send a communicator to learn lantern messaging."

Liu Sili added: "This communication must be reliable!"

"Yes." Wei Chengqing said, "If there is any problem with this communication, wouldn't it be revealed at once?"

"It's not necessary." Pei Shaoqing waved his hand and said, "because no one will spend a lot of effort to buy Wanglou's communication, because these communications cannot reach any secrets."

The money from those ambitious conspirators was not blown by the strong wind.

Officials from government agencies such as Dali Temple are worth buying. It is really not worth buying if a mere Wuhou or a public official in the building is really not worth buying. What's the use of bribing it?

Di Renjie nodded and said, "Pei Sicheng's words are reasonable."

Immediately, Di Renjie called the head of Dali Temple in.

Let the Lord give money to buy lanterns from the buildings in various markets.

Three more communications were sent to the east, west and south respectively.

The efficiency of communicating is still very high. In less than an hour, one communicating 180 buildings in Chang'an City sent a communicating group to Dali Temple to meet.

Taking advantage of this period, Di Renjie and the other four had already drawn nearly 200 three-color lantern comparison tables.

At that moment, Di Renjie said: "The news of each building has arrived at the villa. Are the three of you going with me?"

"We won't go." Pei Shaoqing blinked and said with a smile, "It's been a hard time for Laodi Temple. I, Yushi Liu, and Mr. Wei, are just lazy here."

Liu Sili and Wei Chengqing also understood the joints.

Pei Shaoqing left the two of them to avoid suspicion.

The two of them nodded happily and said, "There is the Laudy Temple."

Di Renjie no longer refused, and immediately took the three-color lantern comparison table and came to the villa of Dali Temple, and shared the principles of the three-color lantern transmission with these legends.

This principle is actually very simple, you can understand it as soon as you say it.

After all, this is almost the same as the previous drum sound.

Di Renjie handed over the lantern comparison table to Tongchuan again.
