Night of the Undead

Bobo didn't notice it at first, but she did eventually.

She was a little embarrassed.

"What's wrong, Matthew? Are you tired? I've been talking too much."

Matthew smiled and shook his head. He pointed to the sky and said,

"It's getting dark."

..

[Hint: You have ignited the "Incense Burner of the Past (high imitation)". Your advancement ritual, The Night of the Undead has already begun!"

..

In the open space.

A faint scent of incense overflowed from the small incense burner.

Matthew sat on a small stool, and a lot of things were spread out in front of him like a stall.

Lucky Rabbit Feet, Cursed Monkey Claw, Bat Teeth, Boar Umbral Vein, Goat's placenta, Water Buffalo Horn, Human's Liver Stones, Small Inferior Demon's Eyeballs…

The fuel in the incense burner was a mixture of rhinoceros horn, ghoul liver fat, and a small amount of butter.
