Actually, the first time they were chased, they could fuse and unleash the Heaven Slaying Sword Technique to kill all the Blood Bats.
However, after seeing Xiao Yaozi, Lin Feng and Lin Fen knew that if they relied too much on that sword, they would only walk the path of Xiao Yaozi.
It was true that Xiao Yaozi was very strong. Even if they walked the path of the other party's swordsman, they could still become extremely powerful.
After all, he was a person who had fought all over the world!
However, Lin Feng and Lin Fen were both proud and arrogant people. How could they follow the rules and walk the path of others? Therefore, they had to walk their own path.
Therefore, from then on, the two of them had an extremely tacit understanding. Unless they were really in a desperate situation, they would never use that sword again.
Otherwise, the more they used, the more they would be affected by Xiao Yaozi.
