The next morning, Lu Kai went inside an S-class dungeon with his squad. They succeeded, but all were injured badly. So ARCEUS healed them with his power. Then ARCEUS asked Lu Kai's team, "Do you all want to train under me?" They all said yes.
So ARCEUS created a hundred stair steps, and he created a gravitation energy on the stairs. Each step's pressure and force increased by 5%. "If you all reach the hundredth step, I will grant you one wish. And also, each 5 steps will grant you a new skill according to your attribute and understanding."
With a wave of his hand, the stair steps came into reality. Then ARCEUS said, "Prove your power of endurance. Trial start now. You all have only 10 days to complete this trial. Use everything you can to step up on this giant steps. By the way, I created an invisible barrier in this guild area so no one can see the portals and these stairs. So now start."
When they all stepped on the first stair, they came to their knees due to the pressure. Then Lu Kai remembered, "Master said, 'Prove your endurance, right?'" So Lu Kai didn't unleash his Frosty powers as support. He just stepped on his feet without any power and then he slowly, slowly stepped forward. Each giant stair was like a vast area. He was getting close to the next step, and his friends were still far behind.
Then he jumped and grabbed the next step, then pulled himself up onto the second step. Then his feet perfectly stood on step 2. The 10% pressure crushed him to the ground. His bones were broken, but he froze his own fractured bones and stood up again.
