Twenty years—this was the deadline Yang Wenxiao set after much deliberation.
Although he was aging day by day, living another ten years wouldn't be an issue.
What about after ten more years?
By then, Yang Hao would be the Emperor of Daqi. Yang Hao's abilities were impeccable, but his personality was too soft. He lacked the commanding aura needed, and if faced with a critical situation, he might falter and hesitate.
Meanwhile, Yang Zheng would be in his early twenties, about the same age Yang Ye is now.
Yang Zheng's potential development by then was an unknown variable, but with a ten-year contract still in place, it would at least secure another decade for Daqi.
Twenty years later, Yang Zheng would be middle-aged. By then, he should have grown into the ideal successor Yang Wenxiao envisioned, right?
