In 'God’s Miracle', when it comes to the Level Gap Suppression' feature of the game, there is a 10% rate of players inflicting only 10% of the damage that they can cause to monsters. Then, there is a 20% rate for players to only inflict 20% of their initial damage. This follows with a 30% rate for players to only inflict 30% of their initial damage. Last but not least, there is a 40% rate for players to only inflict 50% of their initial damage.
In other words, players would never have the chance to inflict more than 50% of their normal damage when the Level Gap Suppression' function of the game is activated, due to the large gap between the level of players and the level of monsters. The strike that Zhang Yang landed on the monster was only 20% of his normal damage.
