There's an ancient saying in Great Ruins, ‘Don’t go outside when it’s dark.’ In Great Ruins, the old, weak and disabled elders of Disabled Elderly Village picked up an infant by the riverside and named him Qin Mu, raising him up with blood and sweat. This day, as the night descended and the darkness shrouded Great Ruins, Qin Mu left home... Become a villain undulating in the spring breeze! That's what Blind told him. This is the rise of Qin Mu's road to becoming a villain!
It wasn't only cultivation, divine arts, and techniques that influenced life and death battles. The mind and knowledge also affected them.
Regarding this point, Qin Mu was well experienced.
There were numerous experts in Dao Sect who would usually calm their hearts down, burn incenses, and take a bath before their life and death battle. Some would even meditate for three days to get rid of all the distracting thoughts in their mind, to not let any thoughts affect their thoughts in battle. They would let them flow naturally.
Even though Xu Shenghua said that he had beat the entire High Heavens and had no opponents on the same realm, the fights in High Heavens were usually not those of life and death battle.
