Performing a high-altitude tightrope walk without a safety net is already dangerous enough, but if we discuss how to increase the danger further, please note that this may pose a great safety hazard and life-threatening risk. Any performance should be performed under safety assurance. Here are some methods that theoretically increase the danger, but are for discussion only: 1. **Increase the height**: Performing a tightrope walk at a higher altitude will increase the danger and risk of the performance. 2. **Reduce the stability of the equipment**: Use thinner wires or make the wires more shaky and unstable. 3. **Increase environmental interference**: Perform in strong winds or extreme weather conditions. 4. **Increase weight or perform complex movements**: Add weight to the performer, or perform complex movements such as jumping and flipping. 5. **Reduce visibility**: Perform in low light or haze weather, making it difficult for the performer to see the surrounding environment clearly. 6. **Psychological interference**: Increase psychological pressure, such as playing distracting sounds or music during the performance. Once again, these methods seriously threaten the safety of the performers, and any performance should be based on the highest standards of safety measures.
