The holy grail of Ihur, the source of blood, what sacrifices are needed and where are the sacrifices?

Choose to build a maze on the tombstone and you will see it.

The Ihur Cup requires sacrifices such as ritual blood 5 and live linear worms.

Most of them can be obtained in the previous maze. Ritual blood 5 can be obtained by brushing a maze with a depth of 4-5, and live nematodes need to kill the big head at the end of the main line.
