The Hall's training ground was very high-end, lacking none of the various functional training facilities. Strong Spiritual Protection made it very difficult for the grounds to be damaged, and its vast area was fully suitable for the free display of High Rank Combatants.
Rod spent one hundred thousand silver coins to open a top-tier training ground.
What made it different from other training grounds was that it had two Measurement Crystals: one could measure the instant fluctuations of Spiritual Energy and calculate the consumption from that, while the other could estimate the Destructive Power of an attack.
Rod tested it and found that with his bare hands charged to the limit, the strongest strike could achieve a Destructive Power of 1000.
The power of the Quick Star Shuttle was 800, whereas the Full Star Shuttle's power was around 5000.
The Deep Sea Hider's Trident increased the power by about 20%, also consuming a corresponding amount of Spiritual Energy.
