Han Lang excitedly followed Sun Liansheng to Old Master Cao's room.
Upon entering, he exchanged a meaningful glance with Gou Xingzhi, who was in the room staring at various instruments.
Gou Xingzhi's eyes turned red upon seeing Han Lang, but as this was the Cao family's residence, he dared not act rashly.
Cao Jian, the head of the Cao family, quickly pulled Sun Liansheng to Old Master Cao's bedside upon seeing him.
"Elder Sun! Please come and take a look, is my father's condition showing signs of waking up?"
Sun Liansheng carefully felt Old Master Cao's pulse.
"The old man's fingers are twitching slightly, indeed showing signs of waking. However, for some reason, the pulse is strangely rapid."
Sun Liansheng's brow furrowed, but Gou Xingzhi then added.
"Elder Sun, there's no need to doubt!"
"The instruments show that the old man's vital signs are normal, and his brainwaves are highly active, which should be a sign of the brain's stress response. I think he will wake up sooner or later."
Cao Jian and Cao Xuerong were overjoyed, but Sun Liansheng's brow remained furrowed. Unable to ascertain the condition, he cast a questioning glance at Han Lang.
Han Lang was intently observing Old Master Cao on the sickbed and did not notice Sun Liansheng's gaze. He too frowned, looking perplexed.
Logically, it was a good sign for a vegetative patient to begin regaining motor functions.
But for some reason, he felt a faint, almost imperceptible frown on Old Master Cao's brow.
Suddenly, he had an epiphany and exclaimed in surprise.
"No, this is a final surge of energy!"
A final surge of energy?
Han Lang's exclamation drew all eyes in the room to him.
"Who are you? Why are you speaking so disrespectfully here!"
Cao Jian's gaze was fierce, and his tone carried a hint of anger.
Sun Liansheng quickly explained upon seeing this.
"Mr. Cao, please forgive him. He was brought by me, and he is also a doctor. Perhaps he misread the signs!"
As Sun Liansheng tried to smooth things over, Han Lang stepped forward, neither humble nor arrogant, and met Cao Jian's intense gaze.
"I say, Old Master Cao's current condition is a final surge of energy! If not intervened in time, he will not live past ten days!"
Han Lang's confidence made Cao Jian unsure of how to proceed. However, Gou Xingzhi, standing beside him, gave a sly smile and said.
"This young friend can be so certain of the illness just by looking from afar. His medical skills must be extraordinary. May I ask what the basis for such a diagnosis is?"
Basis?
Han Lang felt a bit flustered.
There was indeed no relevant basis in the memories of the Divine Farmer Heavenly Physician. However, as a cultivator in the late Tribulation Stage on the Li Chuan Continent, he was very familiar with such situations!
But how could he explain it?
"The cause of a vegetative state, in fact, lies in the brain! In Old Master Cao's case, it should be because his consciousness is trapped within his Sea of Consciousness and cannot escape!"
"Moreover, his fingers twitching slightly and his heart rate accelerating are all phenomena caused by his subconscious anxiety upon discovering this problem!"
Han Lang spoke with conviction, but as expected, Gou Xingzhi burst into laughter.
"Haha... Sea of Consciousness? Little friend, you haven't been reading too many fantasy novels, have you?"
"Don't slander me. I only like reading urban romance novels, not fantasy!"
This exchange instantly made everyone lose trust in Han Lang, and even Sun Liansheng was speechless.
"Heh heh... No matter what you like to read, practicing medicine and treating illnesses must be based on medical theories. Which medical book did you get those wild diagnoses from? Why don't you tell us so we can broaden our horizons?"
At that moment, everyone looked at Han Lang with anticipation.
But how could he explain the path of cultivation to a group of mortals?
"You might not understand the medical theories I speak of! However, I can confidently say that Old Master Cao will exhibit significant movements, such as flailing his arms and legs, within three days, after which he will revert to his vegetative state. He will surely pass away ten days later! Believe it or not."
"Hahaha..."
Gou Xingzhi laughed again.
"In that case, I think we should give this young friend a chance to treat Old Master Cao. If he can wake Old Master Cao up, then it will be a happy occasion for everyone, and we will have nothing to say!"
"If not..."
Gou Xingzhi deliberately glanced at Cao Jian.
"If not, you will be thrown into the river to feed the fish!"
Upon hearing this, Gou Xingzhi finally revealed a triumphant smile, but Han Lang calmly refused on the spot.
"No! I can only stabilize Old Master Cao's condition at the moment, and I am not confident that I can wake him up!"
Stabilizing Old Master Cao's condition with the medical skills of the Divine Farmer Heavenly Physician was a simple matter, but waking him up on the spot would require reaching the third level of Qi Refining, opening the Sea of Consciousness, and stimulating the divine sense. Otherwise, he would be powerless!
"Pfft, after all that talk, you were just playing with us!"
Gou Xingzhi seized the opportunity to add insult to injury.
Cao Jian's anger became more apparent, and even Cao Xuerong's gaze towards Han Lang shifted from disdain to a hint of disgust.
This greatly worried Han Lang.
He could defy power, but he couldn't afford to damage his image in the eyes of a beautiful woman. Thus, he waved his hand grandly.
"Five days!"
"Miss Peach, give me five days. If I can wake Old Master Cao up after five days, will you go on a date with me for one day?"
"And what if you can't?"
"I'll stream myself cutting off my own limb as an apology to the world!"
Han Lang believed such a drastic oath to be extremely convincing. However, Cao Xuerong listened to these words and was utterly speechless, immediately exclaiming in anger.
"What do I need that thing of yours for? To soak in wine?"
Gou Xingzhi also sneered.
"After five days, Old Master Cao might wake up on his own, so why would he need your help? A truly capable doctor should be able to wake Old Master Cao up right now!"
Gou Xingzhi's words were pointed, and Cao Xuerong, understanding the implication, immediately asked with delight.
"Director Gou, do you have a way to make my grandfather wake up now?"
Having achieved his goal, Gou Xingzhi put on an air of detached wisdom.
"Of course! With a dose of adrenaline to stimulate him further, Old Master Cao can be woken up."
Upon hearing this, Han Lang immediately became anxious.
"Miss Peach, do not act rashly..."
"You shut up!"
Before he could finish speaking, Cao Xuerong cut him off. Han Lang had no choice but to stand there dejectedly.
"Director Gou, please do your best to provide treatment!"
Gou Xingzhi, looking smug, unhurriedly took a small syringe from his medical bag, prepared the medication, and injected it into Old Master Cao.
"Thud!"
Immediately after the injection, everyone saw Old Master Cao make a more significant movement.
He lifted his right leg high, then slammed it onto the bed, making a dull thud.
Cao Jian and Cao Xuerong were ecstatic. If this continued, wouldn't Old Master Cao sit up in the next second? Gou Xingzhi also looked confident.
However, things went contrary to their wishes. Old Master Cao did not sit up but instead began to convulse uncontrollably, and the medical equipment beside him kept emitting 'beep' alarms.
Everyone panicked.
"Director Gou, what is happening?"
Cao Xuerong remained relatively calm, but Cao Jian was furious.
"What have you done to my father!"
Gou Xingzhi was now as anxious as an ant on a hot pan.
He had intended to save Old Master Cao to curry favor with the Cao family, but if Old Master Cao met with an accident now, even the Gou family would not be able to protect him.
Already flustered, he had to pretend to be calm and returned to the pile of instruments.
"Mr. Cao, please don't be anxious, let me take a look first!"
Cao Jian had no time to pay attention to him and urgently pleaded with Sun Liansheng.
"Elder Sun, please think of a way to control the situation!"
Sun Liansheng didn't have so many thoughts. He quickly stepped forward to diagnose, but after feeling for a long time, he couldn't figure anything out. He then hurriedly requested Han Lang.
"Young Master, please act quickly and save Old Master Cao!"
Han Lang didn't care about all this. You didn't believe me when I kindly advised you, and now you're begging me? Do you think I'm that cheap? Unless...
"It's not impossible for me to act, unless Miss Peach is willing to go on a date with me!"
Cao Xuerong's eyes widened upon hearing this request.
Isn't this taking advantage of the situation?
Seeing Cao Xuerong hesitate, Cao Jian quickly came over to persuade her.
"Rong'er, I think this young friend is quite good-looking. Just bear with it and agree. Your grandfather won't be able to hold on much longer!"
With time pressing, Cao Xuerong, despite her hundredfold reluctance, gritted her teeth and stamped her foot.
"Fine! It's just a date! As long as you can stabilize Grandpa's condition, I'll agree!"
Han Lang grinned slyly and then calmly took out silver needles from his pocket.
"Take off your clothes!"
"Ah?"
Cao Xuerong felt both ashamed and angry. She had taken a step back, and this guy was pushing his luck with such an outrageous request. Moreover, there were so many people here!
Simply despicable!
"I mean, take off your grandfather's shirt so I can insert the needles!"
Han Lang looked at Cao Xuerong, whose cheeks were flushed red, and was speechless.
Cao Xuerong only then realized, her face burning even hotter. She quickly turned her head to hide her embarrassment and helped to clear away Old Master Cao's upper clothing.
As he began to insert the needles, Han Lang also put away his playful smile and became serious.
His hands moved like lightning, quickly and accurately inserting silver needles into various points on Old Master Cao's body.
With each inserted needle, Old Master Cao's body immediately became calmer.
Sun Liansheng marveled at such an immediate effect.
"Is this the Divine Xi Hand?"
As the eighteenth needle was inserted, all the other needles seemed to be electrified, standing proudly upright, not even trembling slightly!
At the same time, an invisible formation took shape within Old Master Cao's body.
It was as if an ancient divine beast was crouching here, looking down upon the world, and any evil spirit under its gaze could only prostrate itself obediently.
Everyone present was dumbfounded.
Sun Liansheng's eyes widened, and he numbly extended his hand, trembling as he pointed at the silver needles on Old Master Cao, murmuring.
"This... is... Qian... Qian Kun Ding?"
As the needling concluded, Old Master Cao's breathing gradually stabilized. At first glance, he looked more like a sleeping elder, with no trace of his vegetative state.
At this point, everyone finally breathed a sigh of relief.
