"Swish, swish..."
Blood flowed into the coffin, causing it to tremble.
"Swish, swish..."
More blood streamed in, intensifying the coffin's shaking.
"Swish, swish..."
All the blood poured into the coffin, filling it almost completely. At that moment, the coffin shook as if about to jump, the blood inside violently swirling as if boiling.
"Hiss!"
A completely black snake slid out from the slightly opened coffin lid and quickly slithered into the pool of blood.
"Hiss!"
The black snake opened its mouth wide, greedily drinking the blood. The blood inside the coffin quickly diminished until the snake had drunk it all dry.
"Hiss!"
The now swollen black snake, with some difficulty, crawled up to Petra's neck and bit into a vein, injecting the blood.
"Pop! Thump, thump, thump!"
