Bai Yan, the divine doctor, was originally named Bai Yanjing. Born into a family of doctors on the Sun-Worshipping Archipelago, he displayed almost genius-level comprehension of medicine from a young age. By the age of twenty, he had completely mastered all the medical knowledge of the Bai family. By then, his fame had already been well-known across the Sun-Worshipping Archipelago.
However, at the age of twenty, Bai Yanjing's pursuit of medicine did not stop there. Dissatisfied with himself in the slightest, he finally chose to leave the Sun-Worshipping Archipelago and head to the civilized capital of humanity, the Huaxia Empire, in search of what he often called the 'pinnacle of the medical world.'
In the next twenty years, he followed Zhang Zhongjing, the medical sage of the Huaxia Empire, traveling across the empire to aid the world with medicine. His medical skills improved at a genius-like pace. His reputation gradually began to spread across the Huaxia Empire, even showing signs of surpassing that of his mentor, the medical sage. At forty, he once boldly declared, 'The pinnacle of the medical world lies right before my eyes!'
However, just as the entire Sun-Worshipping Archipelago was celebrating and spreading his achievements, Bai Yanjing, together with his teacher Zhang Zhongjing, mysteriously disappeared in a single day. Even a thorough, carpet-like search by both the Sun-Worshipping Archipelago and the Huaxia Empire yielded no clues.
Six months later, Bai Yanjing was suddenly swept ashore by the sea onto a small town on the western side of the Sun-Worshipping Archipelago, where he was rescued by fishermen and reappeared in the world.
But by this time, Bai Yanjing had completely changed. His aura had become low and weak, silent and taciturn, even somewhat decadent. He looked decades older, completely lacking the confident sharpness he once had in his prime.
When faced with the overwhelming questions of the time, he only uttered a single puzzling phrase and then remained silent forever. He took in a few apprentices, opened a clinic on the outskirts of Jingdong City, became a professional doctor, prescribing medicine and saving lives, but barely engaged with matters outside his clinic. He hardly accepted medical appointments outside Jingdong City. And so, he stayed in Jingdong City, living an ordinary life for fifteen long years.However, despite the earth-shattering changes in his life, what he said when questioned had become one of the greatest mysteries in the entire human settlement. Over fifteen years, despite countless speculations, there was simply no evidence to be found, nor could it be verified. At that time, Bai Yanjing said: "Only assassins are the ones who stand at the pinnacle of the medical world!" Such a seemingly rebellious statement was almost completely unsolvable. The final conclusion can only be certain: the key to everything actually happened during that nearly blank half-year. If everything could be clarified, it would naturally explain the reasons for Bai Yanjing's changes, as well as the whereabouts of the Medical Saint Zhang Zhongjing and a series of other questions. However, Baiyaojing's silence also cut off all related clues. ...... \ Watching this Baiyan Divine Doctor busy by Uncle Li Chong's sickbed, Qingyan couldn't help but recall this well-known and very special historical event, feeling as if he had missed something very important. However, after several attempts, Qingyan could never grasp that crucial feeling, and each time it gave him a terrible headache. At this time, Baiyanjing was only fifty-five years old. In this world of cultivating the Dao, this age was just past adulthood. But Baiyanjing's strange aura made him look somewhat like he was in his sixties or seventies. His entire hair was almost entirely silver-white, and the heavy wrinkles had already crept onto his skin too soon. Only his relatively agile body showed a vitality befitting his age. "Young Master Qingyan, patient Li Chong has not suffered any illness. The cause of his illness is a very special anesthetic inside his body, called Tianxin Powder. It can slow down all a person's functions several times faster, but it can double the energy consumption in the body, causing a pathological state of throat dryness and body dryness. In the end, it can make a person appear as if they were in a state of suspended death." "Doctor Baiyan's medical wishes are indeed superb; within just a few minutes, he could fully deduce Li Chong's illness. However, when Hyaku Yanjing spoke, his face showed no expression, showing no sign of his joy or sorrow. His deep wrinkles were like old pines, barely trembling.Pausing for a moment, Bai Yanjing slowly continued: 'Tianxin Powder is extracted from several extremely rare herbs. It is not toxic in itself and will not harm the veins and tendons in any way, but its medicinal effect is incredibly strong. Once it enters the human body, it can last for about ten days, making it a very potent anesthetic. Moreover, due to the rarity of Tianxin Powder in the Sun Worship Islands, an ordinary doctor would not be able to detect its key components.'
Qingyan was suddenly shocked: logically speaking, at that time Li Chong was fighting in the forest and had no chance to come into contact with Tianxin Powder. How could it have entered his body without him noticing?
Excluding the possibilities that Master Doctor Bai Yanjing misdiagnosed or that Uncle Li Chong was hiding something, the problem had to be attributed to that third-tier fierce leopard. And what secrets lie behind the fierce leopard became all the more intriguing.
Within just a few minutes, Bai Yanjing had already handed Qingyan a prescription and said expressionlessly: 'To counteract Tianxin Powder, precious herbs are not required, but these herbs are somewhat uncommon. Young Master Qingyan, you need to come with me to the clinic so I can personally pack the herbs for you.'
Qingyan could not refuse. After bidding farewell to Li Chong and his wife, he followed Bai Yanjing out of the slum towards the clinic on the outskirts.
...
In front of him was an extremely simple building, constructed entirely of wood inlaid with traditional Chinese style. Above the door was a long plaque inscribed with the words: 'Ordinary Doctor's Hall.'
Carrying two or three packages of herbs, Qingyan looked at the clinic's name, personally inscribed by Master Doctor Bai, and his brows twitched. He thought to himself: If the world-renowned Master Doctor Bai were truly an ordinary doctor, then every doctor in this world would be utterly ashamed.
Suddenly, a string of tinkling laughter came from the clinic, growing closer. Before he could react, Qingyan was grabbed by a figure rushing out from inside and pulled along.
The girl running ahead turned her head, and to his shock, it was the mischievous Mu Gong Xiaoyu. She called out loudly to Qingyan:
'Xiao Yanzi, today you have to accompany me in testing medicine!'
At her words, Qingyan instantly forced a bitter smile. Seeing a trace of mischief crawling across Mu Gong Xiaoyu's brow, Qingyan began silently praying for the wellbeing of all living beings.
