Mongolia North of Mongolia

Wu Dingbei, a young man from Beijing, was assigned by his company to work in Ulaanbaatar, the capital of neighboring Mongolia. On the way, he met Li Ming, who ran a restaurant, and You Zhiyuan, a construction contractor. They hit it off at once and became brothers, embarking on an adventure in a foreign land.

At a bar, Wu Dingbei met Aruna, a stripper who fell for him at first sight. Out of loyalty to his girlfriend, Dingbei turned her down. His girlfriend, Xiao Hui, couldn't bear the loneliness and, egged on by a friend, found someone else. Dingbei was heartbroken, but later ran into Aruna again in Beijing.

Li Ming's restaurant business was booming, but the Chinese workers You Zhiyuan had brought with him abandoned him because he had withheld their wages. A Mongolian court ordered him to compensate a Mongolian company for its financial losses. While raising money to help You, Li Ming was robbed and shot dead, never to leave Outer Mongolia.

Wu Dingbei ultimately lost out in an internal company power struggle and left Mongolia, leaving Aruna waiting for him in vain.

Back in China, Wu Dingbei enjoyed a quiet bachelor life for a while, until Lao Wei's return brought news that shattered his peace. The murderer who killed Li Ming had finally been caught, but was inexplicably released six months later.

Burning with rage, Dingbei set out for Mongolia again, selling everything he owned to raise the money. He was doing it for justice, and for his late friend Li Ming.

This time, he was no longer a Chinese company executive traveling on a business passport, but an undercover man posing as an ordinary tourist. He was a hunter, determined to find the murderer and fight him to the bitter end...

The novel portrays Mongolia's geography, culture, and ethnic customs, as well as the setbacks young people face because of flaws in their personalities.
