First of all, the villain should buy a recipe of immortal food in the bookstore and read it. Then, you will find that there is already a recipe for fairy dishes by clicking on the details of cooking skills.

After that, bring enough materials (put them in the refrigerator or personal belongings), open the refrigerator at dinner time (about 17 to 24: 00), and you will find the immortal dish in the command menu ~

If you don't have this option, it means that you haven't learned the recipes of immortal dishes, or the time is wrong (not dinner time)

If there is, but it is gray, you can't order it, which means your materials are incomplete ~
