Indeed, the secret note dropped by Xiang Wentian reveals where Ren Ixing is held captive.
However, simply knowing his location is far from enough to meet him; one must first deal with the four prison guards responsible for watching the tower.
According to the story of Swordsman, as recounted by Yin Bukui, the four jailers guarding Ren Ixing are known as the Four Friends of Plum Villa.
The strength of these four individuals should not be underestimated. The most powerful among them, Huang Zhonggong, though not at the level of Xiang Wentian or Yu Zhenzi, is said to be not far behind.
The reason they became jailers is simply that they don't like power struggles, and prefer to spend their time doing what they love.
So buying a mansion by West Lake and spending their days engaging in music, chess, calligraphy and painting - isn't that a heavenly existence?
Given this jailer lineup, it would be unwise to use force.
