Qian Jin was a little angry. "Father, how can you cheat?"
Qian Rangli snorted. "Jin, there's no war in the Xia Dynasty now, so I taught you to be upright and honest because everyone values honesty. However, once the war starts, as a subject of the Xia Dynasty, you must go to the battlefield. On the battlefield, swords know no mercy, and cheating is a skill you have to equip yourself with in order to survive."
Qian Jin was a little angry. "Father, you are just making up excuses to justify your cheating."
Qian Jin trained hard just so he could defeat his father one day. Seeing that it was about to happen, Qian Rangli taught him yet another lesson.
Qian Jin left from there angrily.
Qian Rangli knew his son very well and was not worried at all because he knew that Qian Jin would understand it one day.
When Qian Jin returned to his courtyard, he locked himself up. He was angry, but on second thoughts, what his father said made sense.
