Rex: The Master Of Poisons

The old man kept wondering about it but no matter how many times he thought, he failed to understand as to how she recovered.

Moreover, when he took a look at Rex, he could find that he had the similar symptoms of what Elina was having a while ago.

High body temperature, a huge amount of sweating and heavy breathing, all of these could be clearly seen in Rex.

"Doctor!? What did happen to him now?", Alex ask d with a tensed expression.

He was indeed happy that Elina was alright now and was crediting the old man for this in his mind. However he didn't have any time to praise him since Rex was in danger right now.

So he thought that he should give more priority to his son rather than some half assed praise.

"I'll look into it?", the old man said and walked towards Rex who was still lying on Elina's lap.

'Huff huff...'

His heavy breathing just continued to increase and it seemed as if his condition was worsening.
