Starting from his vigorous old age, he began to conquer Liaozhai.

Now, demons and ghosts run rampant, and the fate of the Ming Dynasty is in jeopardy.

Having lived two lives, Cao Xiong has a deeper understanding of this world.

The Ming Dynasty's fate will inevitably collapse sooner or later, and when that day comes, the world will surely be a scene of demons running rampant.

He must increase his strength and expand his influence before that day arrives.

During this period, whether it was Wang Er and Lu Qing's research and improvement of firearms, or Zhang He and other military doctors' research on the plague, Cao Xiong realized that although mortals do not know how to cultivate, they still have the ability to overturn the world.

The phrase "the Hundred Schools of Thought" kept stimulating a certain nerve in Cao Xiong's mind.

The source of the corpse plague, Zangpo Long, has been killed, and the corpse plague powder has begun to be mass-produced. The corpse plague seems to be spreading rapidly, but it is just a case of adding fuel to the fire.

"Times have changed; sticking to the old ways will only lead to being swept away by the tides."

Cao Xiong had already conceived a plan for the next stage of development for the Baihu Office.

……

After obtaining the first batch of medicinal herbs, Zhang He passed on the prescription for the Corpse Plague Powder to all the military doctors in the Hundred Households and the temporarily recruited physicians.

They dispersed among the soldiers and civilian households, making plague powder while simultaneously helping the infected civilians.

Shahe Village, Guobei County.

Liu Mingzi's Third Banner was stationed here, and they cleaned up the surrounding area centered on Shahe Village.

There were only two doctors accompanying the army: Zhang He and Mao Dafu.

"Dr. Zhang, help!"

Zhang He was making corpse plague powder in his tent when two soldiers suddenly rushed into the tent carrying a seriously injured colleague.

"Quickly put him on the ground and hold him down!" Zhang He frowned. The soldiers who were carried in were covered in blood, their right arms torn open by the plague zombies, and their eyes were filled with a frenzied desire to kill.

If it hadn't been bound by thick ropes, it would probably have long since become a utterly destructive plague corpse, only knowing how to kill.

Following Zhang He's instructions, the two soldiers held Cai Da, who had already begun to turn into a plague zombie, down tightly.

Zhang He took out a freshly brewed Corpse Plague Powder and presented it to the three of them.

"Hold his head down and don't let him move." Zhang He seized the opportunity and poured a whole bowl of corpse plague powder into Cai Da's mouth.

Not long after, Cai Da gradually stopped struggling, his complexion returned to normal, the madness in his eyes faded, and he slowly regained his rationality.

"I'll give you two more doses of Corpse Plague Powder. Give it to him every three days."

Both officers breathed a sigh of relief and gratefully clasped their hands in a fist salute to Zhang He.

"Thank you, doctor. We thank you on behalf of Cai Da."

"His injury is too severe. If he wants to live, the only option is to cut off his right arm," Zhang He sighed.

Cai Da, who had regained his senses, had a dim look in his eyes. He was a veteran of the Hundred Households Office and had already reached the threshold of the Skin Tempering Realm.

I'll be able to become an inbound martial artist soon; now, none of it matters anymore.

Losing an arm means physical disability, damaged bones and muscles, and the end of martial arts training.

"Dr. Zhang, you've worked hard. Please begin."

Cai Da knew how to prioritize. His colleagues had come and gone, and today it was his turn.

However, he was fortunate to have survived, which is a blessing in disguise.

"it is good."

Zhang He exhaled a deep breath, walked to the depths of the tent, and took out a medicine box.

At this moment, Mao Dafu, who had heard the commotion inside the tent, came in.

When Zhang He saw Mao Dafu, his face lit up with joy. "Dr. Mao, you are more skilled in external injuries than I am. Please take the surgery."

Mao Dafu only glanced at Cai Da's condition before he had a general idea of ​​the soldier's injuries.

He quickly stepped forward and took Zhang He's place.

Mao Dafu picked up the wounded soldier's arm and carefully examined the exposed bones.

Not long after, Mao Dafu took out a datura ointment from his medicine box.

"Applying this will relieve your pain, but the effect is only so-so. Hang in there." Mao Dafu stared into the wounded soldier's eyes. Amputating an arm was not an easy task and required the patient's cooperation.

Cai Da nodded emphatically, "I'm not afraid, Dr. Mao, please begin."

Mao Dafu applied the datura ointment to Cai Da's crippled arm.

Then he took out a bone saw and decisively sawed off Cai Da's right arm.

"Hmm~"

Cai Da's face was contorted with bulging veins, and a layer of fine sweat appeared on his forehead. He clenched his teeth and bit the wooden stick in his mouth in half.

Mao Dafu focused intently on treating the wound without any distractions.

After Cai Da's right arm was sawed off, Mao Dafu switched to a curved knife, used it to cut out the wounded soldier's veins, and tied the blood vessels tightly with mulberry rope to prevent massive bleeding.

After completing this step, the next step is to treat the amputated arm wound.

Mao Dafu switched to using a fine-toothed bone saw.

His hands did not tremble at all, and he cut the bone stubble neatly and steadily.

"Soldering iron~"

Mao Dafu opened his hand and took the branding iron, which had been heated red-hot by charcoal, and repeatedly applied it to the area around the wound on his severed arm.

Nearly two hours later, Mao Dafu finally got up and sat down in a chair.

"Your life is saved, but you can no longer practice martial arts."

Zhang He looked directly into Cai Da's eyes, a fiery glint in them.

Having just escaped death, Cai Da was pale and his body trembled involuntarily.

His gratitude towards Mao Dafu vanished instantly; he had heard that some scholars were homosexual.

"Is Mao Dafu after me? This is outrageous!"

Cai Da was in a state of utter confusion.

"Cough cough~" Zhang He couldn't stand it either and couldn't help but cough.

Mao Dafu snapped out of his daze, looked at Cai Da whom he had just treated, and said, "What do you think if I gave you a new arm?"

As Cai Da breathed a sigh of relief, his heart began to pound uncontrollably.

"Dr. Mao, please explain in detail."

Mao Dafu's eyes gleamed with fervor. "Apes' bodies are similar to humans. I can try to attach an ape's arm to you. If you succeed, you'll not only be able to practice martial arts, but you might also have even greater talent."

Cai Da paused for a moment, then asked, "How confident is Dr. Mao?"

"I haven't tried it myself, but I promise you, even if you fail, it won't cost you your life."

The other two soldiers exchanged a glance, both somewhat astonished. Replacing an arm with an animal's arm—such a bizarre medical technique was something they had never heard of before.

Cai Da didn't think for long before nodding firmly: "I'm willing to try."

Mao Dafu excitedly approached Cai Da, saying, "However, you need to hunt the apes yourself. The stronger the ape, the better the feedback it can give you."

"Brother Cai, don't worry, the two of us will help you. We'll hunt down a monkey demon directly."

Cai Da's two colleagues gave him considerable confidence.

"Dr. Mao, is there a time limit? Can we wait until after the zombie plague is resolved?"

"Of course, no problem!" Mao Dafu nodded hurriedly.

"During this period, you should focus on getting better."

After comforting Cai Da with a few words, Mao Dafu and Zhang He went deep into the camp to make the Corpse Plague Powder.

"Dr. Mao, I never knew you had such skills." Zhang He's tone was full of admiration.

"Actually, I can't guarantee whether this method will succeed; I just want to give it a try." Mao Dafu's face showed a hint of embarrassment.

"Haha, I think it's highly feasible." Zhang He silently clenched the arm he had just sawed off Cai Da's body.

"I also have an idea, would you be interested in hearing it?"

Zhang He suddenly looked at Mao Dafu with a serious expression.

"Please explain in detail, Lord Zhang," Mao Dafu said, puzzled.

Zhang He pulled Mao Dafu to sit down at the table, then placed Cai Da's right arm between the two of them.

"I've also done some research on the zombie plague during this time. I've discovered that the zombie virus is far more complex than it appears on the surface. I'm wondering if we can cultivate the zombie plague."

Mao Dafu's eyelids twitched, and he was so shocked by Zhang He's words that he didn't know what to say for a moment.
