Li Banfeng knew that learning techniques across different cultivation layers was extremely dangerous, yet the "Close Doors and Shut Windows" technique was of great importance to him.
It was not so much that the technique itself was crucial, but rather, the principle behind "Close Doors and Shut Windows" seemed to Li Banfeng to bear certain similarities to territorial Border Lines around different areas.
Convinced by Li Banfeng's persuasion, Meng Yuchun considered the bigger picture and shared the principle of the technique with him. "After reaching the Eighth Layer of Home Cultivation, one first scatters blood around the house, usually in four spots. Connecting these four points outlines the shape of the boundary. Some people only scatter blood in three places, making the technique easier to form, while others do it in six spots, resulting in a more even border line. Ultimately, it depends on the different methods of various individuals."
