However, late at night when Lu Jin was called to his father's study, the man he feared appeared again.
"You followed my instruction. Although you are somewhat obvious, it still went well. However, you have to do something about your expression. You will ruin things for me if people could easily read your feeling and thoughts in your face. To avoid having weakness like that, try to control your expression. It is better if you remain expressionless and cold."
The young Lu Jin did not answer. But he followed his father's words. Perhaps it was the fear that made the young Lu Jin obedient to this man. He did not dare to act stupid or disobey his words.
In the following months, Lu Jin would be called at night and received his father's lesson.
