The story of Su Lanji had left a deep impression on him.
He knew there were people who, despite being seriously injured, still walked several kilometers to deliver a letter. In someone else's shoes, they might have died on the spot, yet he persisted until the letter reached its destination.
This is the power of will.
At that time, Su Lanji was determined to deal with those three ruffians, so took three strikes to the head, yet he remained calm and engaged in dialogue instead of provoking further beatings because his resolve radiated outward, instilling fear in his opponents.
It's like how people's knees go weak when they encounter a tiger.
The three ruffians realized they had come across a formidable person.
This was the starting point of Su Lanji's success.
In terms of will and determination, he had reached the standards of a saint, and everything that followed went smoothly for him.
