To survive in the harsh prehistoric world, one must abide by certain principles. These include avoiding cause and effect, employing strategic planning, concealing hidden talents, and approaching challenges with caution. Establishing a supportive group, speaking decisively, and taking calculated actions are also crucial. However, it is important to exercise restraint and not resort to excessive measures against opponents of lower cultivation levels. Similarly, unnecessary use of powerful resources should be avoided to prevent overkill. Lastly, it is advised not to manipulate others by feigning innocence or cuteness.
