Su Mo had no reason whatsoever to refuse this deal!
He had needed to find a senior after entering the Immortal Furnace to help examine the problems with his body anyway, and this Old Madman seemed to hold an extremely high seniority within the Immortal Furnace!
It was only a drop of heart's blood every six months. With his Divine Body, losing one drop every six months would do him no harm!
Most importantly, the Old Madman would not use him to refine pills for the time being.
Or perhaps the Old Madman had never truly intended to refine him into pills at all.
As for the Old Madman's identity, Su Mo had a rough guess. There was only one possibility for someone who could take him away from the Herb and Wood Ancient Path without a sound: he was one of the Pill Furnace's Immortal Venerables.
But Su Mo knew very little about the Pill Furnace. He did not know how many people it had, or how many Immortal Venerables.
He did not know whether meeting such a supreme powerhouse was a blessing or a curse.
"Thank you, Senior!" Su Mo relaxed slightly and bowed to the Old Madman with his hands clasped.
The Old Madman gazed deeply at Su Mo and nodded calmly.
Solitary by nature, the Old Madman was clearly unaccustomed to dealing with juniors. But now that he had struck a deal with Su Mo, he temporarily set aside some of his airs.
The secrets within Su Mo fascinated him just as much as the Elixir Art he wished to study.
And, as chance would have it, Su Mo's appearance seemed to intersect perfectly with his Elixir Art, leaving him very interested in helping Su Mo unravel his problems.
