   Exciting, captivating, and increasingly enjoyable to read! These three books form a trilogy by Kai Zhongkan. The first is "The Path of Feng Shui Cultivation," the second is "One Man and One Mouse Want to Cultivate Immortality," both of which are completed. The third, "Mecha Immortality Path: Invincible from Exile to Mars," is currently being serialized with stable updates! The three books are set in different eras: "One Man and One Mouse Want to Cultivate Immortality" is set in the late Ming and early Qing dynasties, "The Path of Feng Shui Cultivation" is set in modern times, and finally, "Mecha Immortality Path: Invincible from Exile to Mars" is set in the future. The three books, each with a different protagonist, are independent and cannot be considered prequels or sequels. However, together they could be called a "Three-Step Cultivation Journey"... *The Path of Feng Shui Cultivation* Synopsis: The protagonist, Guan Tianlong, is the heir of a powerful family. He comprehends the essence of cultivation techniques, receives spiritual energy from heaven and earth, and soars to great heights. He also unexpectedly acquires the Nine Dragon Cauldron, thus opening up a new method for forming a golden core. He embarks on a legendary journey using feng shui, formations, alchemy, and weapon crafting, and even contributes to national defense by establishing an aviation industrial park... The story is meticulously structured, grand, and magnificent. *One Man and One Mouse Cultivate Immortality* Synopsis: Ding Yu, a Great Luo Golden Immortal, is attacked by a group of immortals while in seclusion to advance to the Heavenly Venerable realm. During his escape, his primordial spirit escapes with a treasure and disappears without a trace. During a flood in the Wanli era of the Ming Dynasty, an old fisherman surnamed Ding finds a little boy in the Huai River and names him Ding Tianci. Despite many hardships, he finally embarks on the path of cultivation, accompanied by a mouse, practicing both medicine and martial arts. It's a legendary story of a man and a mouse cultivating together, overcoming numerous trials! (This book is especially brilliant and detailed in its descriptions of cultivation techniques and realms!) Synopsis of *Mecha Immortal Path: Invincible from Exile to Mars*: Xu Fan, an ordinary man exiled to a Martian mine, thought he was destined to be a miserable repairman for life. However, a sudden surge from an underground river allowed him to rebuild his cultivation in just six months, achieving the fourth realm of Human Immortal. Now, with the Lingxiao Mecha at his disposal, the *Nine Tribulations Elixir Scripture* by his side, a full energy reservoir, and a plethora of weapons! Space pirates? One punch to obliterate! Oppression? A counterattack to suppress! [Grassroots Rise to Power + Interstellar Cultivation + Mecha Massacre]

    A hard science fiction/cultivation/mecha story. Those who break limits and those with psychic powers are incredibly strong. The female lead, Captain Ma Lianya, has a very powerful backstory; she carries her deceased husband's omnipotent psychic power and will within her. After ending the war in the first part, the second part begins with her returning to the Taoist temple where she once cultivated to report to her master. In reality, this temple is the Human Evolution Research Institute. It's recommended to start reading from the second part; the first part is very intense with its science fiction mecha battles, while the second part combines science fiction mecha battles with cyberpunk cultivation and is slightly more enjoyable.
