"The spirit servant is in a one-sided contract with its master." Cheng Sheng answered. "Since they share a life, the master naturally would know the situation his spirit servant is in. So, he cut the thread of life that they share." He explained. "The spirit servant is originally weak and has been weakened by the Spirit Tracing Bell after it was locked, but suddenly its master cut their thread of life, so…" he didn't continue.
They all cursed.
"How about its master?" Chen Han asked.
"Since the thread of life was cut, he managed to escape." Cheng Sheng's expression turned foul. Obviously, he was angry.
They all sighed.
"Oh, that's right." Cheng Sheng muttered when he remembered something. "Since this is the situation, I've figured that most of them are using one-sided contracts." He told them.
"Why?" they asked.
