Compared with cavalry and war horses, the Tang Dynasty may not necessarily win the grassland. But compared to the number of people, the population of the Tang Dynasty must exceed the population of the grassland.

The reason why there is not enough troops to be requisitioned now is only because of the problem of money and food. Without money and food, I can't afford to support too many soldiers. Do you think Li Er doesn't want to raise an army of millions? He dreamed of it, but unfortunately he had no money, and he was poor and white.

When Yang Guang of the Sui Dynasty conquered Goguryeo, how much more than a million troops? How spectacular is the scene? It's just one word - Howe!

Some scholars have verified that in the end of the Tang Dynasty, the comprehensive national strength did not exceed that of the Great Sui.

If it is really as Du Ruhui said, the grassland is united, and Jieli can have an army of 400,000, can Datang still be able to fight? Can Xiao Rui complete the counterattack of the snake swallowing the elephant?

Absolutely! When Great Qin swept away the Six Kingdoms, Qin Wu'an Hou Bai Qipit killed the 400,000 army of Zhao State, is it the number of people? It's not just the number of people, it's the strength of the country.

Someone has also verified that when Qin destroyed the Six Kingdoms, the national strength of Great Qin alone exceeded the sum of the Six Kingdoms. So take out a Zhao country alone? What about 400,000 soldiers and horses?

But the problem is that the current Tang Dynasty is not as strong as the Great Qin back then, and the current Turks are more than the national strength of the Zhao State back then, and it is not so easy to advance and retreat.

Where did Xiao Rui's confidence come from?

Plug-ins, of course. Potatoes have come out and put into production, and the tame bison in the Northeast have also flowed into the Tang Dynasty, as long as the potatoes have two more stubbles, they can be planted all over the northern land, and there will be a shortage of food at that time?

Then there are ordnance, weapons, armor, war horses, and the like. As the retired veteran factory outside Chang'an City is getting bigger and bigger, the technology of using hydraulic metallurgy and catching up with manual production is becoming more and more proficient, and the speed of Datang's production of weapons and armor has been greatly improved. And it's the minimum standard.

With money, food, and ordnance, all that remains is to recruit people. After experiencing the turbulent times at the end of the Sui Dynasty, the entire Central Plains was riddled with holes, not to mention ten rooms and nine emptiness, and more than half of the staff was reduced, far less than the former Sui Dynasty.

But there are still three catties of iron in the broken ship, and there are still more than 10 million people in the population. As long as the money and food are in place, twenty draws one ding, and you can easily levy an army of 500,000.

Even if 500,000 are all infantry, they are not afraid of 400,000 flying horses in the grassland.

Because Datang Sheng is in a well-equipped and technologically advanced technology. Just imagine, the 500,000 people on our side are all tightly wrapped in high-quality armor, the weapons in their hands are brand new and sharp, and the 400,000 Turks on the opposite side are in rags, no matter how strong the arrows are, what is the use of not being able to penetrate the armor? It's not just an ornament. 400,000 by then? Once they are mixed together, hehe, just wait to be slaughtered by steel knives.

After listening to Xiao Rui's plan and analysis, Li Er was relieved and recognized Xiao Rui's plan.

Du Ruhan breathed a sigh of relief, not being overtaken by the young man, but said heartily: "I knew that everything was in Zangfeng's plan, why should I be afraid to survive these two months?" I have been able to recuperate with peace of mind for a long time. ”

Coming back to his senses, Li Eryi slapped Xiao Rui on the head: "At this time, you are concentrating on how to treat Keming, but you are talking nonsense for a long time?" Why don't you hurry up and save people? ”

Xiao Rui made a mistake: "Du Xiang's illness, I have a mixed method of life and death, if it is ......"

"No if, anyway, it's a dead body, just leave it to you to deal with. Da Lang Erlang, Your Majesty is here today, explain to your father, whether Xiao Rui saves your father or not, you are the benefactor of my Du family, you must not have the slightest disrespect and complaint. ”

Du Wei and Du He had long been taken aback by Xiao Rui's big plan, and they were only afraid and shocked in their hearts, how could they dare to go against Xiao Rui? Hurriedly knelt down and kowtowed, "Yes, the child wrote it down." ”

Xiao Rui nodded: "In this way, then I'll make a prescription, you take medicine and maintain it first, and I'll prepare as soon as possible." ”

"How long does it take to prepare?" Li Er asked with concern.

"A month at the latest."

"A month? Are you going to open a furnace for alchemy? How long is a month? Li Er was puzzled.

Xiao Rui smiled bitterly: "If it is an open furnace for alchemy, it is simple, just concentrate on collecting medicinal materials." The preparation this time is all things that Datang doesn't have, and it would be good to be able to get them together in a month. ”

After saying that, he hurriedly said goodbye.

Sending the emperor and Xiao Rui away, Du Ruhui gave the strictest gag order to his two sons, everything in the room today is not allowed to be leaked out, otherwise don't blame your father for killing his relatives! Du Wei and Du He rarely saw their father's murderous side, they trembled with fright, and hurriedly swore a poisonous oath.

On the way back, Li Er muttered, what Datang doesn't have? So how do you prepare? Could it be the medicinal herbs of the Hu people in the Western Regions?

"Quick, go and tell him that the secret vault in the palace has collected most of the medicinal materials in the world, even if they are rare medicinal materials in the Western Regions." Li Er urged the inner servant Lao Gao to pass the word.

Caught up with Xiao Rui, after Lao Gao finished speaking, Xiao Rui refused, what I said is a set of treasures of Hua Tuo, the holy hand of surgery, which has been lost for many years and needs to be rebuilt, not the medicine.

Lao Gao was stunned, the surgical saint Hua Tuo? Master Pony even understands this? Is this something that Doctor Sun can teach? I only know that Doctor Sun has a magic needle in one hand and a good medicine in the other, but I haven't heard that he can also operate. Also, you said that if you want surgical instruments, you should go to the Ministry of Industry to put the workshop, look at this direction, how is it the West Market?

City? Of course, it has to be Xishi, if you want to have surgery, you need anesthesia and disinfection, Datang has no spirits, and only the good wine from its own liquor shop can meet the standard of medical alcohol after reprocessing and purification.

Not long after, Xiao Rui drove out with a large cart of good wine and went straight to Xiaojiazhuang.

glanced back at Chang'an City, and muttered in a low voice: "It's not safe for the New Year, if this car of wine is sold, it can be sold for thousands of taels of silver, and you must find someone to reimburse it when the time comes." Alas...... This year is destined to not be able to celebrate the New Year in Chang'an City. ”

Xiao Rui did not go to the general of the Ministry of Engineering to be the supervisor, but went into the mountains, looking for the hermit old blacksmith in the mountain, and after leaving the drawings and requirements, Xiao Rui went back non-stop to prepare other things.

If you want to complete a high-quality cardiopulmonary surgery in ancient times, it is absolutely impossible to do it without a plug-in.

Not to mention any environmental problems, a single bleeding and blood transfusion is a big problem.

Disinfection, sterilization, and even a sterile operating room, etc., can be done with a little effort, but after the surgery, the sutures, the later infusion and anti-inflammatory, nutrition maintenance, etc., Xiao Rui has made difficulties, and now it is too late to cultivate penicillin by the local method?

In desperation, Xiao Rui sent a letter to his mentor Sun Simiao Zhenren for help, and he could only brainstorm, hoping that there were capable people in ancient times who could think of ways to replace anti-inflammatory drugs and nutrient solutions.

Half a month later, a clear old man with white hair walked into Chang'an City, followed by a middle-aged Taoist who was about forty years old and had three wisps of long beard and a face like a crown of jade.

"Senior Brother Sun, your disciple has really found the inheritance of Hua Tuo, the Holy Hand of Surgery? It can't be a lie, right? It's been more than 400 years, if Hua Tuo has a heritage, how can it wait until today to appear? The middle-aged Taoist asked worriedly.

Sun Simiao, who had a white beard, stood still, looked up at the majestic and domineering Chang'an City, his eyes narrowed slightly, and he said with a full heart: "My disciple has a benevolent heart and never jokes on the road to practicing medicine. Lao Dao has practiced medicine and saved people all his life, and he once thought about re-establishing the inheritance of Huatuo's ancestors, but his ability is limited, and he has not succeeded. ”

"Since the apprentices have the same ambition, we should do our best to fulfill them. Senior Brother Ge, you have a family history and studied under a master, and I hope you can help you this time. ”

The other party made a head, "Senior Brother Sun, in order to save people from the world and continue to pass on the stunt, Ge Dan is duty-bound!" ”
