At first it seemed that nothing really was happening. However after about three minutes the blood seemed to darken, there was a black liquid forming in the blood, but unlike the counterpart of the old man's blood, this blood seemed to be just in black colouring now. But the black substance remained in the black colouring. Maybe the blood is the culprit, he thought to himself, and as he reached for the remains of old man's blood, he noticed that the blood once more had the black gunk's, and they have gathered more and more and it seems that they are spreading even faster than before.
As final test, Dimitry made the powder solution and placed it in a cup, where he on top poured his own blood. He wanted to see if the reaction would change by any chance. But after waiting for about ten minutes. The blood still was red, but had the black colouring, which again was, as Dimitry dubbed it, black blood.
It seems that the old man doesn't have much time to live, at this rate. Even more so, this much time was spent on making the test on the blood, that he might be on the last breath. That doesn't seem to be a good sign. If anything goes bad, then Dimitry might loose his last true friend. As such, he must hurry. But he knew that the old friend is already on the death bed and was prepared for that. Yet he also knew that the old man needs to have some time to finish the last business.
Dimitry reminiscences an old conversation, that he had together with the old fella, about the time when he would die. He knew that someday it might come, so he asked Dimitry if there was a way to give body full strength, to actual let the person finish last business. At the time he knew of only one substance, and to be honest even now he doesn't know of anything better than this solution. An adrenaline dose, that is highly active. Created from some rather curious materials, and known only by ancient Alchemists and forbidden by the church.
