The first update of rs is here.

"It's the Changsun family." Li Yesi didn't say much, but Wang Kuang, who heard the words Changsun family, was full of surprise and confusion. How could it be the Changsun family? How could it be?!

"Erlang, what are you talking about? Why are you mysterious and then from the Changsun family? It seems that the Changsun family is not in Erlang's expectation?" Xu Guoxu was also confused. He heard Li Yesi's tone, which should be something he had been investigating. Moreover, this secret matter not only involved Erlang, but also Li Yesi...

"It's nothing, it's just the poisoning incident that year. Someone informed us, so we were able to lock in the target as soon as possible. But I didn't know who informed us at that time, so Ye Si has been investigating in the past few years." Wang Kuang recovered from the shock and smiled.

Li Yesi never gave up on the investigation of the two letters to Wang Kuang. There were only a few words in the letters, without signatures or signatures, and it was difficult to investigate. Wang Kuang originally wanted to investigate, but seeing that Li Yesi was so concerned, and although his Li family did not have a secret soldier from Wei Xiaowu like himself, they also had huge connections in various armies. The town generals and county magistrates in many places were all old subordinates of Li Jing, so it would not be inconvenient to investigate. Therefore, in order not to let Wei Xiaowu's men collide with Li Jing's people during the investigation, Wang Kuang did not let Wei Xiaowu's people continue to investigate.

This makes no sense. If the poisoners who later disappeared one after another, Wang Kuang was still a little convinced when Li Yesi said this. Although Li Tai and Li Chengqian were both Changsun Wuji's nephews, their closeness was one on the ground and the other on the sky. It can be explained that Changsun Wuji seized such a great opportunity to inform Wang Kuang in order to pull Li Tai down from the position of the prince who could threaten Li Chengqian's position, and made Wang Kuang a shot.

But later, the poisoners disappeared or died one after another. Li Chengqian was not smart enough, but he had Changsun Wuji's sword Laosan, the grandfather who was so smart that he almost became a demon, would never use such a bad move to use this to add another shameful deed to Li Tai. The technique was too clumsy. Since Changsun Wuji had already made a move, he would not let Li Chengqian use such a bad move and pull him into it.

The incident was clear at the beginning. Wei Xiaowu's people did not investigate who wrote the letter, but investigated who committed the poison. All the clues about who committed the poison were clearly pointed. Li Tai first sent someone to poison, but he only committed two or three times, just to disgust Wang Kuang, so that Wang Kuang felt that he wanted to find a backer, and then he could get close to Wang Kuang; the subsequent poisoning was done by Yu Guangzhao and Yu Qizhong and his son who were instructed by Li Chengqian and later discovered by Wang Kuang and began to silence again. It can be said that the technique was extremely clumsy and made a big deal in the eyes of a big boss who was used to the dispute over power and position. It was so big that many people knew who did it without thinking.

If it weren't for the involvement of the prince and Changsun family, Wang Kuang's temper would have beaten the other party three feet high. But Li Shimin had already hinted that he had stopped and had to sell his face, so the matter was finally left unresolved. He only took the Yu family's father and son, and no one mentioned it again.

So the contradictions and contrasts before and after were too great. Wang Kuang could say that he never suspected that the letter was coming out of the Changsun family. The same Li Yesi and Li Jing did not doubt that they went to the Changsun family, which made their investigation direction completely deviate from the truth. It took so many years to investigate it.

"Tsk, I just came out of the Changsun family, and didn't say it was Changsun's stinky old man. Erlang, why are you panic?" Xu Guoxu pointed it out incisively after hearing the whole story. This made Wang Kuang's eyes lit up. Yes, it was just said that the letter came out of the Changsun family, not that it was Changsun Wuji's work. The Changsun family has grown up, and every big family will have open and secret struggles. Changsun Wuji's support for Li Chengqian does not mean that the Changsun family supports Li Chengqian. At least, as far as Wang Kuang knows, Changsun Yu is not optimistic about Li Chengqian, but rather optimistic about Li Ke, who has no blood relationship with him in the Changsun family. The reason is very simple. So far, the best relationship between the prince and Wang Kuang is Li Ke.

Seeing that Wang Kuang looked at him, Li Yesi shrugged helplessly: "It is true. Xin came from the Changsun family, but his name was not from Changsun's husband, nor was he a child in any clan of the Changsun family or the elders of each house. Instead, he came from an old housekeeper."

It turned out that Li Jing and his grandson had always focused on the aristocratic families and other princes who had grudges with the prince, because only they were more likely to send two such letters, but they did not want to expose themselves to the Changsun family or the prince's nose, so it was understandable to use anonymity.

After several years of investigation, Li Yesi had given up, but the old man Li Jing became interested and could hide it from the martial arts art for so many years. He was really curious. Which expert could have done such a trick and do things without missing a trace? Therefore, Li Jing was not only not discouraged, but ordered the scope of investigation to be expanded.

Finally, accidentally, Li Jing got an IOU from a merchant. The handwriting on the IOU was exactly the same as the handwriting on the headless and unfinished letter in Li Yesi's hand. Then he found a breakthrough and focused his attention on the old butler of the Changsun family.

"It's gone?" Li Yesi's sudden stop made Wang Kuang's heart suddenly break, and the clues were broken?

"No, the old housekeeper had died two years ago. We originally thought he was the housekeeper of a certain room, or started from where he was close to it, but the end result was that the old housekeeper was close to any room, and he didn't have any relatives to any room. The Changsun family only knew that the old housekeeper had been in the Changsun family since he was a child, and had always been unknown and had no strong abilities. If he had not been an old man from the Changsun family and had a reliable and loyal work, he would not have been allowed to be the housekeeper. However, the housekeeper was only responsible for arranging the cleaning and cleaning of the home, and he did not have much power. It was considered a leisurely place for the elderly to be arranged by the Changsun family."

"There is no possibility of silence. The old butler died two years after the poisoning incident was calmed down. Since the incident has subsided, there is naturally no need to silence him. Anyone with a discerning eye can see that the Changsun family is inseparable from the poisoning incident. Moreover, the old butler was terminally ill a few months before his death. The Changsun family also thought that he had followed him for so many years, and specially went to the Imperial Medical Office to invite a doctor to help him see the doctor. The Imperial Medical Office was a medical worker who was a nominal disciple of the Imperial Medical Office. According to him, the old butler died of old age and he could do nothing." Li Yesi looked up at Xu Guoxu and added.

Xu Guoxu originally had something to say, but he kept silent when he heard it. He originally wanted to ask if it was possible to silence him.

This news is equivalent to not. Once the old housekeeper dies, all the clues will be interrupted. Even if someone instructs him, once he dies, it will become a death without evidence. It means that after investigating for so many years, all the hard work is almost in vain. No wonder Li Yesi is not in a good mood.

"Then the old housekeeper has no other relatives or close people?" Wang Kuang was not giving up.

"No, he entered the Changsun family as an orphan back then. He has never been married and is alone when he grows old. The result of the investigation is that the old housekeeper is kind to everyone, but in fact he keeps a distance from everyone. No one knows what his surname is before entering the Changsun Mansion and where is the family? It can be said that none of the entire Changsun Mansion is actually close to him."

"What about his relics? Isn't there anything left?" This is the last hope. If there are any relics, maybe new clues can be found from the relics.

"Everything was buried with him, and even the tables, chairs, benches, boxes, cages and other things that he used during his lifetime were burned." This is a custom. Those who could be buried would be buried together. Most of them would be burned with fire. Taking the deceased to the other side can continue to use these daily necessities. For the Changsun family, a few tables, chairs, benches and other things are not worth a lot of money, and they will burn them after burning. It can also give other living families a demonstration to let them see that even if you die, the Changsun family will not treat you badly, and can make you live a good life when you go to the other side.

"By the way, there is something strange. It is said that before the old housekeeper died, he asked the Changsun family to carve this symbol on his tombstone." Li Yesi suddenly remembered something, took out a piece of paper from his chest, and handed it to Wang Kuang: "This was something that Grandpa asked someone to go to the cemetery at night. He didn't recognize it. He just felt that since it was the old housekeeper who repeatedly told him before his death, it must be unusual, so he went to the tombstone."

With a bang, when Wang Kuang opened the folded rubbing, he felt his mind explode. The symbol that appeared in front of him, or to be precise, should be a symbol. It should definitely not be something that could appear in this era, and it will not appear until at least a thousand years later. However, now it appears on paper!

This is a symbol that everyone on earth knows later generations. Two electrons cross over the sign of circumference of the atomic nucleus. This was once regarded as a symbol of science for a certain period of time. Even CCTV used this as a platform mark in the early years! And there was something next to this atomic symbol, which made Wang Kuang look very familiar.

(Again, it is definitely not double wear, nor too much wear!)
