Outside the door was still the inner courtyard just now, and the three-walled small room where the two of them were now was the ear room to the west of the main house.

Dare to toss them for a long time, and the underground passage walked back, but only from the east wing of the inner courtyard, through the east and main rooms of the main house, to the west room, the difference is that they walked from the underground.

The two knocked on three walls, but did not hear a 'knock' sound, which shows that the walls have no mezzanine. When the oil lamp was used to illuminate it, there was no trace on the wall, and it was almost certain that the wall was also unorganized.

Looking at these three walls and one door, the two couldn't help but look at each other, where did the two nuns come from? This is really a secret passage that has no trace, unless the secret passage is still underground, but the underground just now is only a short passage, and it cannot be regarded as a secret passage, and the handle at the end of the passage is not a mechanism to open the secret passage.

The two of them thought hard for a long time, but they were still helpless about this secret path, so they could only give up.

The tall man who came later looked at the man who came first and asked, "Your Excellency has come here in the middle of the night, and I wonder if the purpose is the same as that of the next?" ”

"What if it's the same, what's the difference?" The man asked squinted at the tall man.

"If it's the same, let's work together to complete this matter, if it's different, your Excellency can be regarded as trespassing on a private house in the middle of the night." The tall man said in a deep voice.

"Trespassing? Hahaha, what a joke! Your Excellency is not here to trespass on a private house? The man smiled coldly.

"Under the entrustment of the Kaifeng Mansion, it is naturally not considered a private house, and your Excellency is the same?" The tall man said.

"Each other, but you and I are 'the same way, not each other'." The first man said sarcastically.

"That being the case, why don't you show your true face" The tall man had not yet said the last three words, and he had already grabbed the black scarf in front of the man like lightning.

The man quickly slid a few steps back, avoided the grab, and leaped to the roof, saying, "If I knew Your Excellency would be like this, I would have taken the next step first." A few ups and downs, like a light swallow, disappeared into the night.

The tall man never thought that he would fall short when he caught it, and secretly said that this person was really thoughtful and responsive. He took off his face towel and revealed a rather cold handsome face, it was Liu Congguang.

Looking at the distant back, Liu Congguang couldn't help frowning and thinking, why was the person's eyes so familiar just now, a bit like the person he had seen.

At dawn, several men came to the Kaifeng Mansion, all of whom were dressed in dust, and the leader was a middle-aged man, who looked quite majestic, but his face was Qirong, but he was Sun Yan, the head of the "Bashu family".

Sun Zi Cong is the third son of Sun Yan, the head of the family, and his eldest son, the heir of the future "Shu Jin Family", but now he suffered this disaster in Bianliang, which made Sun Yan sad and angry, so as soon as he learned the news, he rushed to Bianliang without sleep, hoping to find out the cause of Sun Zicong's death as soon as possible.

Sun Yan came to Bianliang this time to bring the most famous work in Bashu, and the people in the rivers and lakes called "Poison Langzhong" The master of poisoning, hoping that they can find out what poison is in their beloved son's body.

Seeing that the family of the deceased agreed to open the coffin for an autopsy, Lord Yin Chen of Kaifeng Mansion hurriedly instructed the officials in the palace to take Sun Yan and others to the mortuary to prepare.

The autopsy was carried out by Sun Yan with the Bashu Gang as the main examiner, and the Kaifeng Mansion Ya Cheng completed it with cooperation. Looking at his beloved son, who was still alive and well a few days ago, but at this time he turned into a cold corpse, Sun Yanzhi gritted his teeth with hatred, and secretly swore that if he found out who did this, he would definitely break the murderer's body into pieces and leave that person dead without a place to be buried.

After a stick of incense, the two of them glanced at each other, and both shook their heads silently.

Sun Yan hurriedly asked, "What did you two find?" Did the dog die of poisoning? ”

Na Bashu replied, "Master Sun, after the two of us investigated just now, there was nothing unusual about your son's apparent death. The skin is not blackish-purple; The silver needle probed the throat and did not appear black; The stomach and intestines were examined, and no residual toxins were found; There was no abnormality in the internal organs, and there was no poisoning on preliminary exploration. But. After a moment of silence, his face was embarrassed.

"But what? But it doesn't hurt to talk about it. Sun Yan said.

"But the noble son seems to have a good relationship before he dies, please look here among the poisonous langs." The man pointed to a tiny purple line under the corpse, but the purple line could not be seen without looking closely.

"Is it poisoned?" asked the poisonous man who had been watching from the sidelines.

"It's like. But for a moment, I can't tell what kind of poison this is. The poisonous man frowned and pondered.

In the Huimin Pharmacy in the outer city, Zhao Yan reported to Zhao Xian, "Master, those five thieves were caught by our people in the peach blossom cave brothel last night."

"But where did you get it?" Zhao Xian asked.

The five thieves also knew each other, they thought they were all hard bones, who knew that they had not yet been tortured, so they automatically confessed, they were the "hidden gang" that had risen in the rivers and lakes in the past five years, and the "hidden gang" had three halls, and they belonged to one of the halls, called "binding the hall", specializing in kidnapping, looting and other things, as long as the buyer could afford to pay, they would do it. Zhao Yan despised this gang.

"Hidden Gang"? Zhao Xian thought for a while, she didn't seem to have heard of this kind of gang, and then asked, "But tell me who their gang leader is?" Where is the helper? ”

"Back to the master, they are just little minions, and they have never seen their helper, let alone the helper. They also only know that the church site is in Yangzhou, and the hall master is a woman, and they have never even seen the true face of the hall master, because the hall master must wear a mask every time he appears. ”

"Yangzhou? It's actually Yangzhou? It seems that we were in too much of a hurry last time and failed to pay attention to Yangzhou. Zhao Xian was thoughtful.

"Throw these five thieves to Li Er and hand them over to the Kaifeng Mansion to deal with." "What are the results of today's autopsy?" Zhao Xian asked again.

Zhao Yan said the news that had just come from the Kaifeng Mansion again.

"What kind of poison is this? Can't even judge the poison lang? Zhao Xian was quite curious about this poison and sighed, "It would be good if Senior Brother came back." ”

"Oh? Sister, what if I come back? A clear male voice came from the doorway. A man in a dark robe stood by the door, looking at Zhao Xian with a smile, the man had wheat-colored skin, a handsome face, a slender figure, and even muscles.

When Zhao Xian heard this, she turned around happily and said with a smile, "Senior brother, you're finally back, I've been waiting for you for a long time." ”

"You! Are you waiting for me to help you out? Zhao Xian's senior brother Li Yi stepped forward, looked at Zhao Xian and smiled, and said, "I have heard what you just said." When I was practicing medicine with my master, I seem to have heard of this kind of poison. ”

"Oh? Senior brother knows the way? Zhao Xian said as she stuffed a cup of freshly brewed tea into Li Yi's hand.

"Well, this is not a poison to be exact, it is an aphrodisiac, called 'Hongyan'." Li Yi picked up the teacup and took a sip of tea, then sat down opposite Zhao Xian.

"'Red face'? What a nice name. Zhao Yan said.

"Yes, it's indeed a nice name, but Hongyan comes from a saying, 'Since ancient times, Hongyan has been like poison, but it makes men dry bones'." Li Yi sighed lightly.

"Twenty years ago, there was a mysterious sect in the northwest region, called 'Hehuan Gate', whose owner was originally a woman, but no one had ever seen her, and she made the aphrodisiac 'Hongyan'. Later, this sect disappeared inexplicably, and the medicine of 'Hongyan' disappeared. Li Yi said eloquently.

"If it's an aphrodisiac, why is it a poison?" Zhao Xian looked at Li Yi suspiciously.

"Aphrodisiacs are used to help amuse and aphrodisiac when men and women are flirting and having fun, and they are generally mostly taken, and some are used for external application." When Li Yi said this, he looked at Zhao Xian, and saw that she was listening quite attentively, and there was no shyness or blushing, and secretly said that his junior sister was really different from ordinary women's twisting.

Li Yi continued, "And this 'red face' is an internal thing, the usage is quite strange, it is placed in the woman's lower body 'Dan acupoint', and then with the man, if the man who has sex with him does not leak his body, the 'red face' is only for aphrodisiac; ”

"It was from this purple thread that I thought of the medicine 'Hongyan'." Li Yi said.

"Then do you know what shape, what color, and what smell this 'red face' is?" Zhao Xian continued to ask.

"I haven't seen that 'red face', and naturally I don't know its shape and color, but since it is an aphrodisiac, it must have some special smell." Li Yi thought about it carefully and added, "But this medicine can't do any harm to the woman." ”

"I don't know the shape and color, it's quite a headache to find!" Zhao Xian muttered to herself, then suddenly remembered something, and continued to ask, "By the way, Senior Brother, the 'Hehuan Gate' has never appeared again?" ”

"I have never heard of the appearance of the 'Hehuan Sect' again, and it is said that this sect appeared in the Xia Kingdom after the most reluctant. Some people also say that the master of the door is in the Western Xia Kingdom, but these are all rumors in the rivers and lakes and have not been confirmed. Li Yi replied.

'Xixia?' What is the connection between Xiangyin' and Western Xia? Why did they spend money to find a 'hidden gang' to kidnap those women? When Zhao Xian thought of this, she felt that her head was big.
