The next day, when Ye Feng and Xie Zhenliang came to King Su's mansion, Zhang Fatzi was still sleeping soundly in the inn.

This night, he was indeed hard enough. So when he set off for Suwang's Mansion, Ye Feng didn't wake him up, so let him rest for a while.

According to what Zhang Fatzi said when he came back, Imperial Doctor Jian sat in the study all night last night, which was not surprising to Ye Feng, he had long felt that there was something suspicious about this Imperial Doctor Jian. In the event of a sudden change, it is not surprising that the mood is restless.

But what he is more interested in now is the disciple beside Imperial Physician Jian, Zhang Fatzi saw him secretly meeting and talking to a man in white in the middle of the night, it seems that this person also hides an unknown secret!

As for Imperial Physician Jian's family, Ye Feng had already inquired before.

Imperial Physician Jian is very famous in Lanzhou City, and there are not a few people who know him, Ye Feng only rewarded the innkeeper with a little money, so he couldn't wait to tell the location of Imperial Physician Jian's ancestral grave.

Doctor Jane's wife has passed away for several years, and he has an only son under his knees, who has followed his father to study medicine since he was a child.

It seems that there is nothing suspicious about his family, and all the suspicions are on Imperial Doctor Jian and his disciple.

But how should the investigation be carried out next?

Just thinking about it, Ye Feng and the others had already come to the door of King Su's Mansion.

Su Wangfu is located in the north of the center of Lanzhou City, sitting in the north and facing south, it is the time when Emperor Jianwen decreed to allow Su Wang Zhu Ao to move to Lanzhou from Ganzhou, hand-picked Cao Guogong Li Jinglong to Lanzhou to select a site, and built it according to the specifications of "the first class of the Son of Heaven".

The palace took the Lanzhou Prefecture Office of the Yuan Dynasty as the original site, built a large number of buildings, renovated and expanded, and built many luxurious palaces and exquisite gardens. The palace is surrounded by a high wall that has three miles of encirclement, the wall is more than two zhang high, the north side is backed by the Lanzhou city wall, in addition to the south gate that is the main gate of the palace, there are palace gates on the east and west sides, it is almost an impregnable royal city.

There are four tall flagpoles standing at the entrance of the house, under the flagpole is the archway, and on both sides of the main gate behind are squatting two fierce stone lions. The main entrance is a five-frame beam double-slope hanging hilltop structure, the roof of glazed tube tiles, carved beams and painted buildings, very exquisite.

The front of the two vermilion gates above the door is said to be hung in the past is the name of the Jianwen Emperor's own book, now Jianwen has been abolished, the country has changed hands, and then hang his handwritten is obviously no longer appropriate, now the door is hung on the door is a huge plaque that reads "Constitutional Outline of Civil and Military".

The whole mansion looks extremely majestic and extraordinary, Ye Feng and Xie Zhenliang, who were standing in front of the door, couldn't help but marvel in their hearts, they couldn't imagine that in the distant and desolate northwest borderland, this "first-class prince" palace actually faintly revealed the royal momentum in the capital.

There was a team of heavily armed palace guards standing in front of the mansion gate, Ye Feng stepped forward and saluted, and said, "Grass people Ye Feng, ask to see His Royal Highness King Su, and beg for a message." ”

As soon as the words fell, a sentence came from the door of the house: "You are Ye Fengye Gongzi?"

Ye Feng looked up, only to find that there was still a person standing at the door wearing the clothes of a chamberlain in the palace. He looked very young, but he was seventeen or eighteen years old, and he was relatively short, and he was really inconspicuous when he stood beside the tall group of guards.

Ye Feng hurriedly waved at him again and said, "It's the grass people." ”

The young chamberlain was also polite, and replied with a salute and said, "Young Master Ye, please come with me, Your Highness has been waiting for a long time." ”

Ye Feng turned his head and Xie Zhenliang glanced at each other, and muttered to himself in his heart, this chamberlain is clearly waiting for them to arrive here, it seems that King Su has long expected them to come, and he is ready.

The two followed behind the young chamberlain and walked into King Su's mansion. The house was very large and densely packed with buildings, and they passed through several portals in a row, bypassed many corridors, and almost turned dizzy, before they came to the main hall.

From a distance, I saw a tall man standing in the door of the main hall, with a delicate beard, with a lofty atmosphere, looking at them with a smile, it was Ye Feng who had seen it in front of the door of Ma Jingfu before, the fourteenth son of Emperor Taizu Zhu Yuanzhang, and the fourteenth brother of the current emperor, Su Wang Zhu Ao.

Walking into the hall and coming to King Su, Ye Feng and Xie Zhenliang were just about to kneel down to see them, but King Su Zhu Ao took a step forward to support them and said: "There are no outsiders here, Ye Gongzi, you have just done this king a great favor, so you really don't need to be so polite." ”

Ye Feng looked back, only to find that the young chamberlain who had led them in just now had not entered the hall, and had disappeared, and there were only Su Wang Zhu and the two of them in the main hall.

The guest and the host sat down, Zhu Ao's eyes fell on Ye Feng, and asked, "You are Ye Feng Ye Gongzi, who has become famous all over the world in recent years?"

Ye Feng hurriedly stood up respectfully and replied, "The grass people are cheap, how dare they hear about His Highness?"

Su Wang Zhu Ao turned his head to look at Xie Zhenliang again, and asked, "This must be the son of Xie Da Cai?"

Xie Zhenliang also immediately stood up from the chair and said, "It's the grass people Xie Zhenliang." ”

Zhu Ao nodded, waved his hand to signal them to sit down, and asked, "I don't know the son of the British Gong Zhang Fu, why didn't that little fat man come with you?"

Xie Zhenliang blinked and replied, "The fat man is sleepy, and he is still lying down now." ”

Zhu Ao couldn't help but smile when he heard his answer.

Ye Feng was shocked in his heart, it seemed that King Su had already understood the identities and even the characteristics of several of them, and he was really prepared.

At that moment, he said with a straight face: "The grass people came to see His Highness this time to thank him for the medicinal materials sent by His Highness yesterday......

Before he finished speaking, Zhu Ao raised his hand to interrupt him: "Ye Gongzi doesn't have to be polite, those medicinal materials sent by this king are for the treatment of Ma Jianjun, even if you want to thank you, it shouldn't be you." ”

Ye Feng was stunned by this, and he didn't know how to answer.

King Su Zhu Hao paused, looked at Ye Feng and said: "Actually, if you want to say thank you, you have helped this king so much this time, it should be this king who is thanking you." What you are doing this time, this king can also guess one or two, so you don't have to go around the bend, if there is anything you want to ask, you can say it directly. ”

These words were so direct, which made Ye Feng and the others surprised in their hearts, it seemed that King Su had retreated before, and he was ready to have a good chat with them alone early in the morning.

Ye Feng asked with some confusion: "Your Highness has been saying that we have done His Highness a great favor since just now, but the grass people and the others have not done anything, so they are really a little confused." ”

Su Wang Zhu Ao smiled: "You have really helped this king a lot, but you don't know it yet." ”

His next words really surprised Ye Feng and the others: "Actually, this king not only knows the identity and origin of each of you, but also knows that you asked the daughter of the divine doctor Cheng Sansi to diagnose Ma Jianjun yesterday, which is just a play you played. Ma Jianjun didn't suffer from any typhoid fever at all, he was poisoned, there is no doubt about it!"

Ye Feng and Xie Zhenliang looked at each other, and they were extremely shocked in their hearts, it turned out that Su Wang Zhu Ao had already known the truth of the matter!

Ye Feng looked at Su Wang Zhu Ao with some disbelief and asked, "Then why did His Highness send people to send those medicinal materials for the treatment of typhoid fever yesterday?"

Zhu Ao smiled: "The purpose of sending people to send medicinal materials for the treatment of typhoid fever in such a high-profile manner is actually just to cooperate with you and perform this play well." ”

Ye Feng and Xie Zhenliang were puzzled and completely confused.

Su Wang Zhu Ao looked at the look on their faces, knowing the doubts in their hearts, and said in a deep voice: "In fact, this king has moved from Ganzhou to Lanzhou, and in the past few years, he has made great efforts to govern the country and spread his grace, attracting many nearby displaced people to move to Lanzhou, and finally built this Lanzhou city into the first important town in the northwest border, and the people can live and work in peace and contentment, and the prosperous scene here is not lost to many big cities in the Central Plains. ”

Ye Feng and the others nodded, they had already seen the prosperity of Lanzhou City before, and King Su's words were indeed not exaggerated at all.

Su Wang Zhu Ao sighed at this time and said: "It's a pity that while this king is deeply respected by the people in Lanzhou, it has also aroused the suspicion of some people, not only in the imperial court for the military and political measures in the northwest, extremely difficult, everywhere constraints, but also took advantage of the death of Xining Marquis Song Sheng the year before last, so that his son Song Hu came to attack the lord and took over the military affairs of Ganliang in the northwest. ”

Originally, there has always been a sympathy between this king and Song Sheng, the Marquis of Xining, he is in charge of the defense of the Ganliang border pass, and the king has Lanzhou as his backup, and has always cooperated tacitly. But since he died of illness and after the little marquis came, he was wary of this king everywhere, so that there was no contact between the garrison of Ganliang Border Pass and Lanzhou, and he became a lone army. ”

Su Wang Zhu Ao was very careful when he spoke, although he didn't say it explicitly, but Ye Feng and Xie Zhenliang heard it, the person who was suspicious of him was clearly referring to his brother, the current emperor Zhu Di!

Zhu Ao sighed again and said: "Not only that, but he even sent the inner eunuch Ma Jing to lead the black armor guard to Lanzhou to serve as a supervisor, called strengthening the defense of Lanzhou, but the black armor guard only obeyed his orders, in fact, he came to monitor the king. Since this Ma Jian Jun came to Lanzhou, although he has not made any major moves, no one knows whether he has any secret decrees in his hands, which has made the people of Lanzhou panic for a while, and the subordinate officials are even more at a loss. ”

Ye Feng and Xie Zhenliang glanced at each other, the content told by Su Wang Zhu Ao was too sensitive, and neither of them dared to intervene for a while, so they could only be silent.

Su Wang Zhu Ao had a calm face and said with some lamentation: "Who knew that at this time, Ma Jianjun suddenly fell ill. The lingering sick bed did not improve for several days, so the king invited the most prestigious Imperial Doctor Jian in Lanzhou City to go for diagnosis and treatment, and the result of the diagnosis was even more surprising, Ma Jianjun was actually poisoned!"

Ye Feng heard that the topic of King Su had turned to the case of Ma Jing's poisoning, and he couldn't help but perk up and listened carefully.
