The Dynasty of Cultivating Immortality

In the Croburg Kingdom, leap years mark a critical time when all 16-year-olds undergo a cultivation aptitude test on their birthdays. This tradition offers a second chance, especially for children from impoverished families, to be recognized for their potential as immortal cultivators.  
The renowned "Leap Test" can catapult ordinary individuals into positions of power, as seen with Prime Minister Xue Gui, who rose from poverty due to his exceptional talent.  
Today, the Ni family anxiously awaits the test, hoping their eligible members will be chosen and restore their family’s prominence.  Among them is Ni Huibo, an orphan with a mysterious past and hidden talents.  
Will he defy the odds and secure a future for his family?
