Sam left along with the rest of his friends to his residence behind the park.
This house is not as big as a mansion but it has enough rooms to fit everyone. After arriving at the residence, Sam entered his room and immediately sat cross-legged. He closed his eyes and used observe on himself.
He observed the wound on his cheek. Sam sensed some foreign substance entering his body and it is making him a little bit uncomfortable.
He was too focused on General Spark at that moment and didn't notice the surroundings in time otherwise he wouldn't even be hit at all and now he has to take care of whatever that entered his system.
After checking the wound, Sam saw that the foreign substance which has a high possibility of being poison still didn't enter his blood stream, it didn't even enter his muscle tissue. It was still struck in the out layers of the skin due to the cell density.
