Crazy lunatic! Who Provoked this crazy Lunatic

Ruruo was standing in the void looking at the old man with grey hair on the other side with a smile on her face.

But from the perspective of the old man, that smile was not a smile at all. It was more like she was teasing him, but he did not get angry he just had some concerns.

He was supposed to approach the city she was at with his aura realeased unscrupulously, but at the moment it was not going his way. She had blocked his path forward.

"Who are you! Why are you blocking my path?" He asked in a deep voice. For some as old as him, that had lived to experience a lot, it was smart to be careful about the unknown.

But still, he seemed to be someone arrogant deep in his bones. He did not fail to showcase his strength when he asked this question as though not backing down.

Only Ruruo didn't answer him quickly, she was still observing him, after a while she had a bored expression.
