There was always risk in a fight between spirit qi professionals, regardless of whether the intention was friendly or malicious.

If he did manage to kill Liu Yifan in such a public setting, the Radiance Federation would not be able to assign blame.
Otherwise, they would end up the laughingstock of the entire main world.
At that point, even if the Radiance Federation gained another Class 5 Creation Master, they would not be able to command the same amount of respect that they currently did.
Qian Yu had not expected Liu Yifan to attend the Radiance Hundred Sequence selection.

Although Qian Yu had agreed to Li Yang's terms, it would also mean that he would have to put himself at risk.
