How cruel the battlefield of the Cold Weapon Age was, I'm afraid only those who have been on the scene will know.

As the saying goes, one will make ten thousand bones dry.

But Cheng Biting Jin didn't become a general from the beginning.

Those who start as pawns know the importance of military doctors best.

Sometimes it may not be very bad, but a quack doctor is enough to kill him.

Sometimes, if there is a miracle doctor here, even if it is just a sigh, people can save you!

Exactly because of this.

After hearing Lu Heng's words, Cheng Yanjin became excited on the spot!

His big fan-like hand grabbed Lu Heng and said:

"Boy, can you really heal a person who can see the bones easily?"

"If this is true, the old man can introduce your means and tools into the army!"

"Do you know that in every battle in Datang, how many wounded soldiers died in time to be treated?"

"This is a great thing for the benefit of the country and the people!"

But what he didn't expect was.

The young man in front of him shook his head and forcibly broke his hand open.

"Uncle Cheng, I also thought about what you said before."

When it comes to human life, Lu Heng is serious:

"And nothing else."

"For needle and thread suturing, I use sheep intestines, and I don't have the conditions to use this kind of thread on the battlefield."

"Take 10,000 steps back and say that you use ordinary needles and threads to suture, and then remove the stitches......"

"Medical alcohol is also not enough."

"If you want to supply it to the army, I definitely don't have enough production now. Do not suffer from a small number but suffer from unevenness, and when the time comes, who will it be used first? ”

He spoke so seriously and seriously, Cheng Yanjin was the first time he had seen him.

So when Lu Heng refused reasonably, the latter did not immediately rush to the eye.

Cheng Biting Jin pondered for a long time, and also said:

"If we're just worried about not enough production, we can tell Your Majesty and let him make the decision."

"It's a big deal, just make a royal property and build a piece of land."

"You have the means here, you just need to increase production, right?"

Hearing this, Lu Heng shook his head with a smile.

He thought about it and took Cheng Yanjin to the backyard.

"Uncle Cheng, you can take a look at the device I use to make alcohol."

"Due to technical limitations, this is the only thing that can be made at the moment."

"Maybe in the future, when the technology is mature and the official distiller can be made, it can be mass-produced."

"But it's too early to scale."

"The raw material I use is wine, and to put it bluntly, it is grain. Something made of food, no matter how useful it is on the battlefield, there is no way to convince His Majesty to give up the people's livelihood. ”

"You can't do this."

Looking at the tools made of water tanks, clay pots, bamboo pipes, and sheep intestines in front of him.

For a while, Cheng Yanjin fell silent.

He understood that Lu Heng was not talking nonsense to himself, but telling the truth.

No matter how useful these things may be, for His Majesty, the scale may not be able to hold it firmly when it comes to using large quantities of grain for winemaking.

It is inevitable that the ministers in the court will not agree!

Half a day.

Cheng Biting Jin said in a deep voice:

"Well, according to you...... What are the conditions for producing this thing in large quantities? ”

Lu Heng sighed.

If you don't say one, two, three today, I'm afraid this stubborn cow will not be able to leave.

He knocked on the bamboo pipe next to him with his hand and said leisurely:

"First, I had to do a lot of experiments to make a specific shape of glass, which is necessary to make a still."

"Second, food."

"When the people of the Tang Dynasty can eat enough, have surplus food at home, and be able to deal with drought and floods, Your Majesty will agree to this deal."

Cheng Yanjin was speechless.

He was so angry with Lu Heng that his face was flushed!

After a long time, he stretched out his finger to land Lu Heng, and his voice trembled:

"The first condition is still the ...... that can be achieved by manpower"

"But the second one, you just don't want to do this job, do you?!"

"Let the people of the world know the etiquette with confidence."

"When the old man died, I didn't know if I could see that the world was so peaceful!"

Lu Heng spread his hands.

This is purely because Cheng Yanjin has no knowledge, and he can't be blamed.

Isn't that what he was born in?

Ordinary people can be fed and clothed, they can have books and schools, poor families have subsistence allowances, and no one will die because of cold, fever and myrrh.

It's achievable!

He arched his hand with sincerity on his face, and said:

"Uncle Cheng, I've really seen such a world."

Cheng gritted his teeth and asked:

"When, where?"

Lu Heng didn't want to lie to him, and he couldn't say that he was a traverser.

After careful consideration.

He decided to come up with the same excuse as before.

Lu Heng said sincerely:

"I've seen it in my dreams."

——The life of modern society, for the people of the Tang Dynasty, is no different from dreams!

………………

Half an hour later.

Inside the medical hall.

Cheng Chumo comforted his father, who was about to faint, and glared at Lu Heng angrily:

"I know you're straightforward, but you can't keep doing this!"

"My dad is also old, what if he gets angry!"

Lu Heng was stunned.

After sitting here for a long time, Cheng Yanjin finally smoothed out that breath.

He let out a long sigh and stared at Lu Heng.

"You don't want to get involved in the military, and the old man can understand."

"But just now, the little girl at the door told me about the injured you treated."

"Tigerheads, right?"

Cheng Yanjin slowed down and said:

"The old man doesn't have a good impression of these gangs, but the Tiger Head Gang is really not a mess."

"It is precisely because of this that the enemies of the Tiger Head Gang are almost all over Chang'an City."

"Among them, the one with the most momentum is the Iron Wolf Gang."

"Do you know what's behind this?"

Lu Heng frowned.

Tiger Head Gang, Iron Wolf Gang...... The names of these gangs, are they running zoos?

And it's a little too secondary!

None of that aside.

Between gangs and gangs, apart from grabbing land and business, what can they have?

"Huh...... You still don't know Chang'an City. ”

Seeing Lu Heng's blank expression, Cheng Yanjin shook his head with a smile:

"The so-called gangs, the people behind them are just various families, or other forces."

"Although I don't know the number of roads of the Tiger Head Gang, the Iron Wolf Gang can't wait to hang the people behind them on the surface."

"They are the five surnamed Qiwang who specialize in dirty work."

"Now, do you understand what I mean?"

The moment he heard the five surnames and seven hopes, Lu Heng understood.

He has already made a feud with the Zheng family among them.

Now, he has helped Tiger Head help his subordinates heal their wounds......

I'm afraid that I have already become a thorn in the side of those families, a thorn in the flesh!

"Anyway, you should pay more attention."

Cheng Yanjin knocked on the table meaningfully, and then left here with Cheng Chumo.

Only Lu Heng was left sitting in place.

Half a day.

He coldly spat out a few words.

"Since you've got into trouble with ......"

"Then find a way to kill them one by one."
