Chapter 685: Offering to the Pill

Langya Immortal Land, Yi Three Cave Mansion.

Langya Immortal Land is a convergence of spiritual energy in Yongle Immortal City, with three hundred and sixty-nine cave mansions opened, rented to the city's cultivators for their Breaking Threshold endeavors.

Of course, the rent is very expensive, and ordinary cultivators can only indulge themselves when advancing to a higher tier or breaking into a great realm, all for the sake of improving their success rate.

Wang Chen had stayed in Langya Immortal Land for ten days, renting a cave mansion solely for the purpose of practicing the Mysterious External Alchemy Technique he had recently acquired.

The Mysterious External Alchemy Technique is quite famous in the immortal realm and is considered one of the best External Core techniques. It is said that its creator was a Power Men cultivator known by the immortal name "Mysterious."
