Immortal Herb Space [Reborn]

In 2043, smog blanketed the world, Earth's resources were running low, and disease was rampant. To adapt to Earth's worsening environment and compete for better places to survive, all kinds of spiritual cultivation quietly began to flourish. The key to curing disease and cultivating spiritual power was the Nine Immortal Herbs: dendrobium, Tianshan snow lotus, a three-tael ginseng root, a 120-year-old fleeceflower root, sixty-year-old poria, cistanche, wild mountain lingzhi, pearls from the ocean floor, and cordyceps. People regarded them as the rarest treasures and sought them frantically. P.S. 1. This is an escapist story set in an alternate future. The author has a wild imagination, and there may be plot holes, so detail-oriented readers beware. 2. It will remain a one-on-one romance and must have a happy ending. 3. Both leads are sexually inexperienced, in both their lives. 4. Please don't search for spoilers or repost.
