The contract signed, Tang Qi formally issued the reward for the "rubber fruit," and the price was as expensive as he'd imagined, painfully so even for his own fortune. However, compared to the potential benefits, spending a few Divine Grace Coins was more than worth it.
Sweet Water City, a renowned city in the Southern Federation Region, though still far from the Yama Jungle, its influence subtly reached there. If he opened the Mysterious Market there, Extraordinary Materials from that vast jungle and Transcendents could flow into it.
If there was a way to obtain the rubber fruit without having to go to the birthplace of the Original Secret Medicine School, that would be the most reliable method.
Once the rubber fruit was in hand, Tang Qi could make a breakthrough to become an "Original Apprentice."
After success, he would be able to prepare a much wider range of Secret Medicines, no longer as limited as now with few choices.
