This crucial information was recorded in detail and without error in Feng Qingyun's booklet.

The life, conduct, loyalty, family background, and interpersonal relationships of each minister are all meticulously detailed in this booklet.

Like a meticulously detailed traditional Chinese painting, it laid a solid intelligence foundation for Qin Qianluo and others' plans.

The reason why Qin Qianluo and others chose the Imperial Study as the location for setting up the formation was due to three meticulous and far-reaching considerations.

Firstly, the Imperial Study, as the core area where Ning Yuancheng fulfilled his duties as regent, acted like a powerful magnet, attracting him to come there every day in a routine manner.

This place was piled high with memorials from all over the country, concerning the rise and fall of the nation and the suffering of the people. As the regent, he had an inescapable responsibility.

Thus, without Qin Qianluo and others going to great lengths to concoct a complex scam to lure him in, he will naturally follow his usual routine and step into this carefully laid "net" without any precautions.

This strategy of going with the flow cleverly avoids many risks that might be caused by deliberate inducement, much like throwing a stone into a calm lake to minimize ripples.

To minimize Ning Yuancheng's vigilance and ensure the plan proceeds quietly and steadily, like a meticulously planned chess game where every step is full of hidden secrets.

Secondly, the location of the Imperial Study bears witness to a poignant and heroic chapter in history.

In the past, during the Ningchen Star Palace Incident, Eunuch Li, the Grand Eunuch of the Directorate of Ceremonial, with unparalleled loyalty and determination, led a group of equally loyal guards to fight to the death to stop the rebellion.

Knowing full well the disparity in strength, they did not back down, building an unbreakable defensive line with their own flesh and blood until their last breath.

In the end, they died heroically, defending the dignity of the royal family and the continuation of their bloodline with their lives.

Upon hearing this tragic news, the Emperor was devastated and deeply moved and impressed by the loyalty and righteousness of Eunuch Li and the group of secret guards.

To commemorate their great achievements and bravery, the Emperor issued a special decree posthumously honoring Eunuch Li and his group of bodyguards.

According to ancestral custom, eunuchs were not allowed to be granted the title of marquis. In order to express his respect and praise for Eunuch Li, the emperor bestowed upon him the posthumous title of "Yongjie," which was of great significance and full of respect.

This is to commend him for his noble character and great spirit of sacrificing himself for righteousness in the face of life-or-death choices.

Apart from Eunuch Li, who has two adopted sons, none of the other secret guards have families.

These royal guards were all carefully selected from the many orphaned and destitute children in the mortuary from a young age.

In the mortuary, the lives of the orphans were like falling into an abyss. They were starving and poorly clothed, and food and warmth seemed like an unattainable dream to them.

After being selected for the royal family, they embarked on a brutal training journey that was like purgatory.

The training process is extremely rigorous, requiring participants to endure high-intensity physical training that is beyond the imagination of ordinary people.

Every day before dawn, they have to get up and run, climb, and fight in the cold wind until they are exhausted.

They also had to learn various exquisite yet secretive and deadly assassination techniques, tracking skills, and methods of infiltration. The slightest mistake could result in injury or even death during training.

However, even with such arduous training, for these orphans, being able to eat and stay warm in the royal family is already a blessing from fate and an immense stroke of luck.

Although these orphans may have the opportunity to start their own families when they grow up, they have long been accustomed to facing everything alone because they grew up in a lonely and cruel environment.

The need for emotional connection has diminished, and few people choose to get married.

Even as adults, they remained alone, yet they found peace and freedom in this solitude, dedicating all their loyalty and passion to the royal family.

The emperor wanted future generations to remember the heroic deeds of Eunuch Li and his secret guards, so that they would become role models for future generations to admire and learn from.

They specially commissioned skilled craftsmen to create a stone tablet, with powerful and vigorous characters to record their heroic deeds in detail.

At the same time, their names will be solemnly enshrined in the Martyrs' Shrine so that future generations can worship them and remember them every year.

Under the Emperor's careful arrangement, one of Eunuch Li's two adopted sons became the Emperor's right-hand man, serving the royal family faithfully.

One followed the Crown Prince, diligently assisting him in handling various complex affairs, offering advice and protection.

This arrangement not only demonstrated the Emperor's remembrance of Eunuch Li, but also, to some extent, comforted the Emperor's grief and guilt caused by Ning Chenxing's escape.

It's as if, in the long river of history, these loyal and brave men have found an eternal resting place.
