What kind of painting could have captivated the knowledgeable Professor Dong? It must have a remarkable origin. Titled "A Thousand Miles of Rivers and Mountains," it's one of China's ten most famous paintings. Since the artist vanished from sight shortly after completing it, speculation abounded about his whereabouts and cause of death. This avid historian, once again, stepped in to investigate the fate of this promising young artist, whether he was murdered or committed suicide due to depression. After careful investigation, the truth finally emerged: as rumored, the artist had indeed died from overwork. Her dedication to this painting, even to the extent of her life, demonstrates her extraordinary devotion.

This painting, "A Thousand Miles of Rivers and Mountains," is a color painting on silk by the talented young artist Wang Ximeng of the Northern Song Dynasty. No two scenes in this 18-year-old's painting are the same. It's worth noting that while it dates from the same era as "Along the River During the Qingming Festival," "A Thousand Miles of Rivers and Mountains" is over four times larger in terms of canvas size.

This mysterious painting made a stunning appearance at the 2008 Beijing Olympics, becoming the only traditional Chinese painting on display at the time; it then starred in the highly anticipated first episode of the "National Treasure" program in 2017; and the story behind the dance-poem "Only This Green" that became a hit on the 2022 Spring Festival Gala stage is the work of its author.

Such a rare and precious work of art has only been publicly exhibited three times in nearly a century. In modern times, this legendary scroll remains treasured within the collection of the Palace Museum in Beijing. However, to Professor Dong's surprise, a journey through time allowed her to personally touch this long-desired painting. At this moment, cradling "A Thousand Miles of Rivers and Mountains," Professor Dong feels immense satisfaction and happiness, as if her life has reached its peak.

Not long after, when Sun Mofei took out all the ancient objects that were considered "old things" one by one and filled a table or even half of the yard, even the usually expressionless Fifth Grandpa couldn't help but twitch his face a few times.

In reality, it wasn't that Sun Mofei was gullible; rather, her family's nanny had been implicated in a recent human trafficking case. Now, the entire county knew the executed nanny was the Sun family's servant. Although the nanny had no involvement in the crime, people still wondered: Why would someone willingly serve her? Wasn't it because she was rich and powerful? She sensed she was becoming a target of public criticism and couldn't afford to stay any longer. So, she quickly disposed of any belongings she couldn't carry with her and left.

At this time, Professor Dong came to visit. So, many things are destined to happen.

At this moment, her only concern was whether she could escape. She noticed suspicious individuals watching her from all directions, but she had no idea whether they were after her or the Sun family's wealth. If anyone knew she was the eldest daughter of the fourth branch of the Hangzhou Sun family, they would have fabricated all sorts of excuses to imprison her.

Several years ago, her brother had buried many gifts from the family in the mountains. Now her brother had gone to Shanghai and had not yet returned, and she was still reluctant to leave because she was worried that her brother would not be able to find her when he returned.
