If you can't even find lime, then you might as well find a corner and bash your head in.
Additionally, if you want a higher concentration of garlic extract, you can, like Xu Yun, use a simple salt bath to promote enzymatic hydrolysis, or more advanced, add a condensation reflux.
To make a condenser, get someone to make a copper tube and soak it in water. (This theory is sound because I've personally tested it before writing this chapter, successfully creating garlic essential oil, which I used to dip dumplings in soy sauce and vinegar during Chinese New Year.)
So Xu Yun never understood.
Why do some protagonists in those time-travel novels insist on tackling logical loopholes to purify penicillin, instead of tinkering with garlic extract, such a foolproof magical tool...?
The sight returns to the original place.
Xu Yun then opened the garlic residue that had undergone a salt bath for enzymatic hydrolysis, added the anhydrous ethanol he brought, and let it sit and wait.
