Lu Deyin had been intelligent since she was young. Otherwise, she wouldn't have noticed the abnormality at such a young age, and her father wouldn't have told her about such a life-threatening matter.
At that time, Second Brother Lu had been betrayed by his elder brother and father one after another. He had also been placed under house arrest and threatened with his children. Filled with despair, he felt that he would not live long, so when his daughter asked, he told her everything.
He knew that his daughter was smart and good at enduring. He told her that if he died, she was the only one who could protect herself and her brother and ensure they lived on. Therefore, she had to endure it and face her grandfather and uncle with a smile.
