Clue

"How can an ordinary person like me get to know a big shot like the Netherworld King? Mister, you are very humorous." It was rare for the boss to meet someone who was interested in buying his 80% pills.

"I often go to the Dragon's Head Shore to try my luck. I've personally seen and gotten close to the Netherworld King before. I've tried it for myself. These Yin and Yang Pills can ensure protection against the Netherworld energy. The other Yin and Yang Pills in the market are inferior goods just to make up the numbers. Most of them are impromptu purchases made by various people who went to the Land. The quality of those pills varies widely. Those pills have no quality assurance and will not last long upon reaching the Dragon's Head Shore, let alone lasting until you meet the Netherworld King," the boss said with a smile.

Wang Zhong nodded. "Is there still a lot of people heading there?"
