William thought for a moment and said in the channel, "How about this? I'll set a goal for you guys. It's impossible for you guys to beat me, so I won't set the requirement of obtaining the reward to beat me. As long as you guys can hold on for a certain amount of time, you can receive free teaching if you reach it. If you don't reach it, hand over an arbitrary rune. If you exceed the time, then I'll give you the rune you want."
"How about it? Can you accept this condition?"
After William stated the condition, it immediately caused a discussion among the others.
"I can make it, but you haven't clearly stated how long we can hold on for."
"This is not bad. After all, it is indeed a dream to beat the first place. However, if you can hold on for how many seconds, there is no problem. There is a chance to take a gamble."
