A divine healer, a general, a young marquis! Who can rival them!

The more renowned Jishetang became, the more bizarre and unusual the illnesses that came to them.

One afternoon, a wealthy family surnamed Sun from the west of the city arrived in a sedan chair, rushing to the east of the city. The man, the Sun family's steward, immediately knelt down upon entering: "Divine doctor, please save my master!"

Yang Hu ordered his men to bring the patient in. Inside the sedan chair lay an elderly man in his sixties, his face pale and his forehead covered in cold sweat. He was clutching his lower abdomen tightly with both hands, writhing in pain and groaning in suppressed groans.

"What's wrong?" Yang Hu asked as he placed his hand on the old man's pulse.

"I can't urinate... I can't go!" The steward was so anxious he was incoherent. "It's been three days! Not a single drop has come out. My lower abdomen is swollen like a pot, hard and painful, I feel like I'm banging my head against the wall. Several doctors in the city have examined me and given me lots of diuretic medicine, but it's all been useless, it's only gotten worse. I even fainted from the pain just now..."

Yang Hu pressed his hand down the old man's lower abdomen. Sure enough, the area below the navel was swollen, hard, and full. When he pressed it, the old man screamed like a pig being slaughtered.

He already knew what was going on. This was urinary retention, commonly known as difficulty urinating.

When ordinary doctors see someone unable to urinate, they assume it's due to water retention and desperately try to clear the obstruction with diuretics. But the root of this old man's illness wasn't "excess water," but rather "a blocked outlet." His bladder was already overflowing with urine, swollen to its limit, but the outlet was completely blocked. No matter how much diuretic medicine was administered, the water couldn't be expelled, and it only made the already bulging bladder even tighter.

If this continues, the bladder will rupture, and urine will flow back into the abdomen; even a miracle won't save the patient.

The old man was in excruciating pain, banging his head against the wall and rolling on the ground. Several strong servants held him down to prevent him from injuring himself. The matriarch of the Sun family, who was standing guard nearby, was crying so hard she nearly fainted. She had even secretly arranged for her coffin to be prepared. In the eyes of everyone in the room, this old man already had one foot in the grave.

"Treat this illness with diuretics, but you're treating it the wrong way," Yang Hu said in a deep voice. "It's not that he has too much water, it's that the water can't get out. The outlet is blocked, the more you try to drain it, the more swollen he becomes, and the closer he is to death."

The doctor from the west of the city who accompanied him was a seasoned practitioner with thirty years of experience, and it was he who had just prescribed a diuretic. Hearing this, the man's face flushed red, and he retorted, "If urination is blocked, is there any other way but to diuresis? In my thirty years of practice, I've always treated urinary retention with diuretics. You, a mere twenty-something with no medical knowledge, dare to spout nonsense here? Who can bear the responsibility if someone's life is wasted!"

Several other doctors nearby echoed his sentiments, their eyes filled with disdain as they looked at Yang Hu. A young man who came from a humble background, even with some empty reputation, dared to overturn their decades-old practices?

"Yes," Yang Hu said, uttering only one word.

He asked Lu Yan to bring a bunch of fresh scallions, picked out the thickest and straightest one, cut off the hollow middle section of the scallion, wiped it carefully with the hot liquor, and carefully trimmed off the pointed end, leaving a rounded opening.

Everyone in the room was completely baffled. What ailment could a single scallion stalk cure?

The quack doctor from the west of the city scoffed, "A scallion stalk... Is this some kind of magic trick, you miracle doctor?"

Yang Hu ignored him. He covered the old man's lower body, leaving only the area to be treated exposed, and held the cleaned scallion stalk in his hand. He aimed at the acupoint and inserted it very gently and steadily.

This technique demands the utmost care. Too light, and it won't penetrate; too heavy, and the delicate orifice will be broken, leading to disaster. It relies entirely on the feel of the hands, pushing it in inch by inch, pausing when encountering resistance, and then using the lubrication of the oil to smoothly advance further. The onlookers dared not breathe, watching the young doctor's focused expression and steady wrist, as if he were holding not a scallion but a thin thread binding a life.

This is an ancient method clearly recorded in medical books from previous generations. Hundreds of years ago, physicians used scallion leaves as tubes, dipped in oil, to slowly guide the flow of stagnant urine, saving countless lives. The hollow and soft scallion tubes, after being dipped in oil, become both slippery and resilient, neither harming the delicate orifice nor failing to reach the obstruction, making them an ideal material for catheterization.

Catheterization is not a rare procedure; what is rare is that doctors in this world have completely forgotten about it. When they see a patient unable to urinate, they only know to force-feed diuretic medicine, preferring to watch the patient die from bloating rather than think of this small scallion tube.

He took some clean grease and carefully wiped the scallion stalks with it. Then he asked Qin Ying to hand him the scalded items and hold the patient down. Qin Ying, disguised as a medicine boy, was very steady. He handed over the items and supported the patient without making a single mistake, and he didn't give himself away at all.

The moment the scallion stalk was inserted, the old man convulsed in pain. But the next moment...

"It's out! It's out!" the manager shouted in disbelief.

Following the hollow scallion tube, the urine that had been held back for three whole days, almost bursting his bladder, finally gushed out. The old man's tense abdomen visibly relaxed, and his pale, distorted face gradually eased and relaxed.

"Hah..." The old man let out a long, long breath, as if he had been forcibly pulled back from the brink of death. His cloudy eyes regained their light. "It's not bloated anymore... it's not bloated anymore..."

The room was deathly silent.

The doctor from the west of the city stood there with his mouth agape, his face flushing red and then turning pale, still clutching the packet of unused diuretic medicine in his hand, unable to utter a single word for a long time.

The steward of the Sun family and several servants knelt down before Yang Hu in unison: "Miracle doctor! You are my second father! So many doctors in the city said there was no hope, and after three days of treatment, his condition only worsened. But you, with your simple skills, pulled my old master back from the brink of death in just a few moments!"

The old lady of the Sun family was also helped over, trembling, and bowed repeatedly to Yang Hu, tears streaming down her face. The few doctors who had just echoed the doctor from the west of the city and looked down on Yang Hu were now all bowing their heads, wishing they could disappear into the ground.

"Get up," Yang Hu said calmly, while explaining how to care for him and how to gradually regulate his Qi. "The root of his illness is stagnation in his lower abdomen. As he gets older, that passage gradually narrows and becomes blocked. Today's scallion tube only relieved the immediate crisis, releasing the stagnant water and saving his life. In the future, we need to use medicine to slowly clear the blockage, warm the Yang Qi, and eliminate the root cause of the illness. Otherwise, it will become blocked again every now and then."

He wrote down the prescription and carefully instructed on dietary restrictions, daily routines, and other matters. The steward of the Sun family wrote everything down and held the prescription as if it were a priceless treasure.

When the old man was carried away, he was already able to speak and express his gratitude.

This miraculous story of "saving a life with a scallion stalk" spread throughout the city in just a few days. Everyone said that the miracle doctor in the east of the city could cure any disease: he could bring the dead back to life, and he could clear the urinary tract with just a scallion stalk. All the old doctors in the city who had been practicing medicine for decades combined were no match for him with just one finger.

The threshold of Jishetang was almost worn down by people seeking medical treatment. In the eastern part of the city, whenever a family had a difficult or serious illness, the first thing they thought of was to seek out that miraculous doctor surnamed Yang, as if as long as they entered the door of Jishetang, there was no disease that could not be cured.

Yang Hu knew in his heart that the more renowned his medical reputation was throughout the city, the closer he was to the gate of the military camp to the north.
