At first, people simply thought that the poison of Tiannan was a rare poison.

But after experiencing the incident of Bai family, these four words turned into a huge question mark, which was deeply printed in everyone's mind.

In fact, not only Qi Cheng and Liu Bin are puzzled, but also Bai Xiaotian and the bald old man are very curious.

What kind of poison is Tiannan poison?

Why does it have a two-year incubation period like a disease?

How strange and special it is, it can not only set off a big scene of internal strife in the Bai family, but also make Dean Ren and Mr. Bai feel scared when they mention it.

Facing Qi Cheng's inquiring eyes, Jiang Chen said with a smile: "in fact, I don't want you to know what Tiannan's poison is, and I hope you will never touch this kind of poison from now on."

"Why?" Qi Cheng asked.

Jiang Chen did not rush to explain, but asked: "have you heard of Tiance mansion?"

Liu Bin scratched his head: "what? A place name? "

"No, it was a department set up by Li Yuan himself in the Tang Dynasty." Said here, Qi Cheng looked at Jiang Chen: "is this kind of poison related to Tiance mansion?"

"Yes, since you know Tiance mansion, what's the role of Tiance mansion?" Jiang Chen asks again.

Qi Cheng thought for a moment and said: "modern historians have different opinions on the role of Tiance mansion. In official history, it is said that Tiance mansion is a nominal department. In unofficial history, it is said that Tiance mansion is a secret agency specially used by Li Yuan to monitor the ministers of the imperial court after the Xuanwumen incident."

Hearing this, Liu Bin said with a smile: "I know about the Xuanwumen incident. Isn't it Li Er who killed his brother and younger brother? Do you mean that Li Yuan's establishment of this department is to worry that some people will follow Li Shimin's practice of killing and killing their brothers in the future to rob their Li family? "

Qi Cheng said with a smile: "this statement only exists in unofficial history. It's hard for anyone to determine whether there is a real Tiance mansion in the real Tang Dynasty. Besides, even if it is, it may not be the same as what we know. Otherwise, how can it be called the most mysterious organization of the Tang Dynasty? "

Jiang Chen shook his head and said, "no, Tiance mansion is real. The reason why later generations have different opinions on him is that Li Shimin and Li Yuan deliberately used it to confuse outsiders."

"To confuse the outsider?" Qi Cheng asked.

"Yes, Tiance mansion was built by the Emperor himself. Do you think what the emperor made is just a virtual decoration? So those who believe in it are quite afraid of these three words, while those who don't believe in it either live to the end of their lives with their disbelief, or go to the end of their lives with this secret after they have really seen the strength of Tiance mansion. "

Jiang Chen put out his hand and said with a smile: "besides what elder brother Qi said just now, the real role of Tiance mansion is to help Li Yuan and Li Shimin get rid of their differences and support their cronies. To put it bluntly, it's like the spy now, it's more like the killer now. They only live in the dark, no one knows what they look like, and no one knows when they will be around them. "

"So, Tiannan poison is one of their means of killing people?" Qi Cheng asked.

Jiang Chen nodded and said: "yes, but at that time, the poison of Tiannan was not called this name, but ten years old."

"I've heard the former president Ren say that." Qi Cheng nodded.

Jiang Chen said with a smile: "at that time, the three words" decadence "had two meanings. One was that swallowing this poison only had a life span of ten years at most. The other was that if you didn't take the antidote, the degree of decadence would be equal to that of normal people every year."

Liu Bin asked: "so in a nutshell, there is a ten-year incubation period, and it will be ten years old?"

After looking at Jiang Chen nodding, Qi Cheng asked, "but didn't you say before that the ingredients of this poison are not fixed? What's more, Mr. Bai said that the incubation period is only two or three years, not ten years as you said

Jiang Chen held out his hand and said, "what I just said is just the predecessor of Tiannan poison. The reason why the later description appears is that this poison has been evolved by human beings."

"Evolution?"

"Yes, in ancient times, the ten-year-old poison was only a kind of poison. Although it was strange, it did not reach the level of fear. Because of this, it continued to the end of the Ming Dynasty."

At this point, Jiang Chen paused for a moment, and his face also showed a look of awe: "at the end of Ming Dynasty and the beginning of Qing Dynasty, because of the chaos of war in China, the people were in dire straits. Nuerhachi, the leader of Nuzhen tribe, founded the later Jin Dynasty, and then Huang Taiji went south to the Central Plains to change his name to Daqing.

The poison of Tiannan was evolved when they went south. At that time, in addition to the scuffle between the two dynasties, there was also a mess in the river and lake. At the beginning, there was a family with the fifth surname in the river and lake. The ancestors of their family are the people who were in charge of the development of herbal poisons in Tiance mansion. "

"Fifth? And the last name? " Liu Bin asked in surprise.

Qi Cheng said with a smile: "from the first to the eighth, there used to be surnames, most of which were the fifth. But now, except for a few places where there are such surnames, it's very rare everywhere."

Jiang Chen nodded, and then said: "at that time, the fifth family was the family raised by the Ming emperor. When they all felt that the Ming Dynasty was coming to an end, they secretly sent someone to contact Huang Taiji and others, not only to protect the family from war, but also to cling to the upper Qing Dynasty."

"At first, Huang Taiji was disgusted with this kind of trick family, but later, after many people's dissuasion, they agreed to support the fifth family like the Ming Dynasty, but the condition was that they could help develop at least five of the most powerful poisons. The fifth family immediately agreed to it. After all, they are good at poisons."

"However, they produced many kinds of poisons one after another, which did not satisfy Huang Taiji. In addition to all kinds of complicated things during the period, the gap between them became bigger and bigger. In less than a year, Huang Taiji ordered the fifth family to be killed. "

"After hearing this, the fifth family fled all night, but it's not the king's land in the world. No matter how they run, their pursuers will show up. "

Said here, Jiang Chen's words changed: "that day, they went to a town on the border to settle down. But before they settled down and had a good meal, the pursuers had arrived. Rao had all kinds of poisons, but his fists were hard to beat. In the end, 132 people from the fifth family were killed. "

"All killed... And the poison?" Liu Bin can't help interrupting.

Jiang Chen waved his hand: "there are 133 people in the fifth family who escaped. When they settled down, a 16-year-old child ran out of the street with money because he wanted to eat sugar gourd. Because the sugar gourd that he bought after running several streets became his life-saving straw, and also created the poison of Tiannan!"

"Sixteen years old? The poison of Tiannan? What happened in the meantime? " Qi Cheng asked.

Jiang Chen lit a cigarette and took a puff, then said: "when he fled, the pursuers didn't know. After killing all the 132 people, they not only relaxed their guard and celebrated in the town, but also made the emperor come to see what was so strange about the mysterious fifth family.

However, on the night when Huang Taiji continued to lead his troops to the south, all the people in the whole town died. It was the 16-year-old boy who made the whole town a dead city, and it was the 10-year-old boy who made everyone spend the night together! "

"Then why is it called Tiannan poison?" Liu Bin asked.

Jiangchen mouth Yang Yang, word by word said: "because, that young man named the fifth day South!"
