Eternal Night Potion Era

Blackbirds swallow the sun, eternal night falls, magic drugs run rampant in the wasteland, and the Mechanical Church enslaves all living beings with divine chips. Lin Beichuan, a pharmacist who was assassinated in his previous life, did his first thing after his rebirth - refining medicine. Hemostatic ointment saves people, blood-burning agent kills enemies, a bottle of Po Yue Dan shatters the iron laws of Tianheng Mansion, and a potion of chain-breaking medicine exposes the millennium scam of the Mechanic Church. Collect medicine in the wasteland, the barrier becomes the king, the hunting god slays the demon, and the medicine witch god comes. He climbed up from the mud of the market town and refined the most powerful medicine in the world, as well as the brightest light. The moment the artificial sun rose into the sky, all races bowed their heads and the darkness receded. His name is Lin Beichuan, known as the King of Medicine. If you have light in your heart, you will not be afraid of darkness.
