Tang Yue quickly took out a cauldron from her space pearl and placed it on the ground right next to Charlotte.
She then lifted her hand up in front of the elf and used a small knife to cut a deep wound on her hand.
Blood slowly dripped from her hand and fell into the cauldron.
Once a decent amount of blood was collected, she then materialized several tongues of flame on her other hand and placed them on the cauldron.
The blood droplets inside immediately sizzled from the heat.
Using this blood as the base, Tang Yue added a few thistle leaves and sprig flowers to the concoction.
After about 5 minutes, and a few more ingredients later, a thick residue settled at the bottom of the cauldron.
"Meh. This should do." Tang Yue nodded satisfactorily.
She quickly scooped up some of the paste and shoved it into Charlotte's mouth.
"What… cough… cough… What the hell are you doing?" The elf weakly mumbled.
