Xu Yiwen and I had obviously come to the same conclusion.
Everyone was already aware that the undeads that were killed were not 'humans' anymore. They couldn't be called 'undeads' anymore.
If Xu Yiwen's and my bold guess is correct, then they are probably some kind of strange living being between a human and a zombie that could be created by this research institute using living people
