Fang Mu, who was used to having his blood taken, did not resist having his bone marrow drawn.
The thumb-thick bone-sucking blood leech, with a dark red body and strange purple-brown patterns, twisted restlessly in Fang Mu's grip.
Its body secreted a slick slime.
Fang Mu almost fumbled and dropped the bone-sucking blood leech.
He didn't rush to let the leech latch onto his arm. Instead, he continued to rub and squeeze the leech's body hard.
So that it secretes even more slime!
The slime of the bone-sucking leech has a strong local anesthetic effect.
Drawing marrow and blood are two different things.
The leech has to pierce the bone with its mouthpiece and Fang Mu certainly didn't want to be wailing in pain inside the house.
As scholars have analyzed, if the slime secreted by the bone-sucking leech did not have an anesthetic effect,
the pain of marrow extraction by the leech would even exceed that of childbirth.
