Sunkei (寸勁, Sunkei) is a special fighting technique of Kaioh Retsu.
Using the principles of the Chinese Kenpo, or the release of internal power, Retsu is capable of delivering full-power blows at nearly no distance. This effectively means that all of his attacks are knockout punches no matter what range he throws them at.
There's also a technique named Musunkei and it's an improved version of Sunkei.
