In reality, it wasn't that Wallace forgot to close the door, but rather that Song Jian had come too quickly, not even giving Wallace a chance to close the door, let alone explain in advance.
However, Wallace knew clearly that within Manor Castle, no matter how formidable the defense array was, it couldn't stop Song Jian from entering.
Song Jian waved his hand, indicating he didn't mind. His gaze swept over the lab, finally resting on a nutritive tank in the middle of the lab.
This was a tank similar to a glass coffin, filled with a light green liquid. Suspended within the liquid was a human body, with tentacles reminiscent of arthropod joints spreading out from the interior wall of the tank, intermingling with various parts of the body, providing the nutrients the body needed.
Song Jian examined this human body carefully. Pale skin, tightly closed eyes, a somewhat thin body with not much muscle, and a quite handsome face. He judged the age to be between twenty and thirty.
