Riz, a fresh graduate, has spent a year searching for employment. He admits to having no exceptional talents and considers himself rather average. His sole redeeming quality is his diligence. After numerous unsuccessful interviews, he begins to lose hope but refuses to succumb to despair. Determined, he prepares for what will be his final interview.
Indeed, it turns out to be his last. On the way, an accident occurs.
When Riz regains consciousness, he finds himself in a dense forest, wearing torn, bloodstained clothes.
"T-this...", Riz stammers, noticing his body seems much smaller than before.
It doesn't take long for him to grasp the situation. He has been reborn as the youngest son of a count.
In this new, less advanced world, Riz, who once lacked ambition, now faces a dilemma. Initially, he aims to live quietly, enjoying the wealth and privileges of nobility. However, circumstances steer him in an unexpected direction.
One event leads to another, and soon, he finds himself at the pinnacle of power.



Arquebus:
The lack of explanation regarding barrel production and the manual manufacturing of arquebuses raises questions about the feasibility and efficiency of such processes without advanced machinery or smelting techniques.
Cannons:
The absence of a comprehensive explanation regarding the creation of cannons, especially cast iron cannons, leaves uncertainty about the availability of necessary resources, such as coal, for their construction.
Gunpowder:
The origin of saltpeter, a vital component of gunpowder, is not adequately addressed in the narrative. It is essential to establish a believable source of saltpeter and sulfur for sustained large-scale ammunition production.
Steam Engine:
While the introduction of a steam engine is intriguing, the story lacks details about its creation and the protagonist's ability to manufacture precise parts without access to machine tools or advanced engineering techniques.
Blackout:
The abilities and capabilities of the Blackout group, particularly their exceptional infiltration skills, may seem overly powerful and not fully explained within the context of the medieval setting.
Russell:
The abrupt transformation of Russell from a peaceful painter to a murderer lacks proper character development and motivation. It would benefit the story to establish dissatisfaction or conflicts within Russell's life before depicting him as someone capable of such actions.
Travel:
The ease with which characters traverse between different countries without established roads raises questions about the feasibility and time constraints involved. Additionally, the annual meetings of Blackout members, requiring extensive travel, seem logistically challenging in the absence of efficient transportation systems.
Overall, while the Kingdom Building series offers an engaging plot, there is room for improvement in providing more detailed explanations and addressing the logical and technical aspects of the depicted time period and technological advancements.
