But on second thought, it didn't seem possible. The Grand Elder didn't need to do that. If he wanted the gun, he could've just taken it back in the valley and killed them. It would've been much easier than now. Lin Yi could see that the Grand Elder didn't want to kill him, either.
If that was the case, this yellow spring sect might really exist, but who was the master talking to when he shouted "Lin Yi will kill me" before he died? Could it be that he had some kind of communication device on him? Did he report it to his headquarters?
However, all these were secondary. When he returned, he would ask boss Bai about the blood-clad yellow spring sect when he had the chance. Boss Bai was once the sect master of the five elements sect, which was even higher than the ancient level. If this organization really existed, he should know something about it.
