Su Mo started the investigation from inside the mansion. He asked his trusted guards to carefully investigate all the servants in the mansion who had the opportunity to come into contact with the old marquis's food, but did not find anything unusual, so he ruled out the possibility of an action inside the mansion.

From this point of view, it at least shows that the inside of the Marquis' Mansion is safe.

If there is no chance to attack inside the palace, then the only chance is to purchase ingredients from outside the palace.

The huge mansion has dozens of kinds of food imported every day, not including the oil, salt, sauce, vinegar and rice purchased regularly...

This was a huge project, but fortunately, hard work paid off and the trusted guards finally caught a butcher this morning.

"It's a butcher named Hu."

The trusted guard said, "The old marquis loves to eat meat. We have been buying meat from him in the past few years without any problems."

Su Mo asked: "Is there something wrong with this butcher?"

The trusted guard shook his head and said, "No, he is fine. Someone soaked the bamboo leaves he used to string the meat with poison. In order to avoid being discovered, the dosage was very small. It wouldn't be harmful if you take it once or twice, but it's hard to say if you take it in a month or two."

Su Xiaoxiao asked: "Why didn't others get poisoned?"

The trusted guard replied, "The old marquis only likes to eat the most tender ribs, and they are always prepared for him. The chefs in the mansion occasionally steal a bite, but firstly, they don't eat much, and secondly, there are several chefs in our mansion, so it's not always the same chef who eats it. But they have been feeling a little dizzy recently, and they just think they are too tired and don't take it seriously."

It seems to be chronic poisoning.

Su Mo asked, "Where is the vendor selling rice dumplings?"

The trusted guard said embarrassedly: "He was caught... but I didn't keep a close eye on him, and he bit his tongue and committed suicide."

Su Xiaoxiao said: "Most people can't bite off their tongue."

This is a trap, set up specifically for the old marquis, no, perhaps it is a trap set up for the entire Zhenbei Marquisate.

Su Mo was obviously not satisfied with the result. He did not get angry and remained gentle. However, Su Xiaoxiao noticed that the guard's forehead was sweating profusely.

The eldest son of the Su family is not as simple as he seems.

"But..." The trusted guard took a breath and secretly thanked God that he did not stop there. He continued his investigation.

"That man's name is Xiangzi. He came to the capital in October last year, around the end of the month. He followed a caravan, but somehow he got separated from the caravan and ended up living on the streets. He later found a job as a temporary worker in a grain and grass shop, and the rice dumplings were sold in that shop."

"The shop hasn't found any problems yet, but according to the shop assistants, Xiangzi has a mistress in a wealthy family. One time, a shop assistant caught them and Xiangzi threatened him not to tell anyone, otherwise he would kill her."

Su Mo frowned: "Which wealthy family?"

The trusted guard hesitated for a moment and said, "The Protectorate Palace."

…

After his trusted guards left, Su Mo fell into deep thought.

"What are you thinking about?" Su Xiaoxiao asked.

Su Mo said solemnly, "Last October, a major event happened in Zhenbei Marquis Mansion."

Su Xiaoxiao looked at him and motioned for him to continue.

Su Mo said, "Grandfather and father had a big quarrel in the study. That day was grandmother's birthday party and many guests came. Grandfather threatened to abolish father's position as the crown prince, and this word spread. Grandfather had just broken up with father when a 'peddler' came to poison grandfather. I think this may not be a coincidence."

"Why are they arguing?" Su Xiaoxiao asked.

Su Mo said seriously, "In order to move the ancestral temple, my father proposed to move it to the capital. My grandfather disagreed and got very angry. In fact, it was just a rant. How can a father and son have a grudge overnight? But people's words are scary. In aristocratic families, there are countless cases of sisters hating each other, brothers hating each other, and fathers and sons hating each other."

Su Xiaoxiao: "Oh."

Su Mo glanced at her and said, "If you hadn't discovered that my grandfather was poisoned in time, the worst result would be that my grandfather would be gone, and all the evidence pointing to my father's patricide in order to keep his title would have come out."

Su Xiaoxiao: "Oh."

Su Mo: “…”

Su Mo opened the snack box on the table and pushed it to her side.

"Hmm?" Su Xiaoxiao looked at the jar full of cracked walnuts and blinked strangely.

"Don't you like eating this?" Su Mo asked.

Su Xiaoxiao picked one up and looked at it over and over again.

"How is your uncle doing?" Su Mo asked.

When they left yesterday, Su Cheng was still in a coma. They could see that Su Cheng was traumatized. In order to prevent Su Cheng from being traumatized again, they decided to return home first.

Otherwise, given the old marquis's personality, he would have to bring Su Cheng and his entire family back with him.

Su Xiaoxiao briefly described the situation of Old Man Su.

Su Mo was silent for a long time after hearing this.

"It's okay if you don't remember."

He said.

You can roughly guess what that painful memory is without asking.

My great aunt used her own life to hold back the assassin, giving her own flesh and blood a glimmer of hope.

It is very likely that Su Cheng witnessed his mother being brutally murdered.

He was only a six-year-old child at the time, and this scene would have been difficult for anyone to bear.

Neither of them mentioned letting Old Man Su recover his memory. Restoring his memory would only bring pain, without any benefit. As for whether there would be clues to the murderer in Old Man Su's memory -

Are they dead?

Or are they so incompetent that they need to use such a method that would make Old Man Su so miserable to find clues?

Su Xiaoxiao would not allow anyone to hurt Old Man Su, including herself.

Old Man Su has suffered too much, and she doesn't want him to be sad for the rest of his life.

Just leave the revenge of the past to her.

She would not let any of those people go. ——Lihua Lane.

After Little Tiger and Second Tiger got up, Big Tiger showed off to his two naughty brothers the sweet time he and his mother had walking the pony together and eating roasted sweet potatoes together.

The two tigers were so jealous that they ran to the gate, but they waited for half a day but their mother didn't come back.

The two felt aggrieved and were about to cry.

Da Hu: “Lululu!”

Who told you to stay in bed!

Erhu and Xiaohu are very fierce.

My brother really deserves a beating today! "Okay, don't be angry, grandpa will roast sweet potatoes for you guys."

Su Cheng went to the kitchen and roasted two big, black sweet potatoes.

Erhu and Xiaohu refused in their hearts, but seeing their grandfather's face was blackened by the stove ash, they finally reached out their little hands and took a piece of roasted sweet potato...

Uh ah.

It tastes so bad——

Afterwards, Su Cheng took the three little ones to stroll in the alley.

Qin Canglan just came back from a trip.

I happened to pass by Zhuangyuan Street and remembered that my granddaughter seemed to be learning piano in Lihua Lane.

"Go to Pear Blossom Lane."

He said to the driver.

Do you have a monthly ticket? 　　The kind that allows father and son to meet.
