They were two completely different people with two completely different names and two completely different lives.
They were like two parallel lines that would never touch each other. Even if they were going in the same direction, they would never touch each other. This was Su Ming and Si Ma Xin before this battle in Freezing Sky Clan.
Even when they started exchanging blows, the odd similarities that the people watching found were yet to come into existence, but as they continued attacking each other, everyone noticed, and it could even be said that the two of them were the last ones who noticed it.
As the onlookers watched the battle continue, the feeling that these two were similar became stronger.
