Luck is nonsense most of the time, but at some point, it's real, and you can really see it.

So when faced with the emperor's excited inquiry, Huang Ren and Ma Yuan's scalps tightened, and cold sweat almost came down.

"Goo-dong!"

After swallowing his saliva vigorously, Huang Ren hurriedly shook his head desperately and said, "Your Majesty, this is definitely not the case!" The method we used was definitely not 100% effective, and our previous experiments only had a success rate of 83.7 percent...... This time it was very lucky, and the soldiers in his hands were in good health, so he was able to not kill a single person and not cripple a single person...... Your Majesty, it's just good luck! ”

Huang Ren said as Ma Yuan nodded desperately.

They don't dare to say big things in front of the emperor in order to be in the limelight, otherwise how many wounded soldiers will die in the future? Or what if a powerful person was injured and the emperor ordered them to go for treatment, but the other party died?

Seeing them like this, Li Shimin was stunned.

It's not because of Huang Ren's luck that he said, at most it's only eighty percent or something, but because of the words that this guy just said about testing, eighty-three percent, and physique, the emperor just can't understand it at all!

So after a pause, Li Shimin smiled and waved his hand and said, "Okay, and there is no need to be nervous...... Huang Ren, the test you just talked about and the ...... Well, what does that mean? ”

After thinking about it for a while, Li Shimin didn't remember what that word was said.

"Eighty-three .seven percent?"

Blinking, Huang Ren asked cautiously.

"Yes, eighty-three .seven percent!"

Nodding, Li Shimin asked with a gentle smile, "What does this sentence mean?" And what does that test mean? ”

Putting down the newcomer slightly, Huang Ren hurriedly explained: "Back to Your Majesty, this experiment and even what the king taught us means that things that have not been determined need to be tried, for example, after the sergeants are injured, we have to clean their wounds, disinfect them with spirits, and then suture and bandage them with thread...... These practices are very particular, for example, the wine used for disinfection must be strong to a certain extent, and the cloth used for bandaging must be clean and must be steamed. None of this has ever been done before, so when we do it, it's a matter of experimenting to see if it actually works! ”

When he said this, Huang Ren paused for a moment before he continued: "As for the eighty-three .7 percent, it was also taught by the Great King to calculate it, but it is to use the Tianzhu number to calculate the proportion of wounded soldiers who have recovered after our diagnosis and treatment!" Eighty percent is eighty percent, eighty-three percent is eighty percent three, and eighty-three percent is eighty-three .7 percent...... In fact, it is just a little more finely calculated. ”

“……”

The corners of his mouth twitched twice, and Li Shimin instantly had a headache.

Tianzhu numbers?

Of course he knew about this thing, and even knew that Li Yuanjia's kid had someone engrave a set of book engravings, and printed out 300 sets and put them on sale in Xinhua Bookstore...... Anyway, Li Shimin remembers very well that when he heard the news, he almost smashed his beloved cup, and finally endured the anger in his heart.

Six books, a whole set of engravings!

Even if Li Yuanjia has his own engraving craftsmen in his house, how much effort does it take to make the engraving of this set of books? Coupled with the use of Han Wang paper, as well as the high-quality ink produced by Han Wangfu, how much will it cost to pay for those 300 sets of books?

Just think about it, he Li Yuanjia has lost a lot!

Not to mention 300 sets of books, even if he sells 3,000 sets, it is impossible to recover the capital. Not to mention the so-called "Mathematics" on how to use Tianzhu numbers, how many people in Datang are willing to read it? And when those who read books see the word "learning" on the book cover, it's good not to scold people directly!

But......

After frowning, Li Shimin pursed his lips and pondered.

Although he was a little dissatisfied with the Tianzhu numbers, Li Yuanjia once sent him a set of books, read them roughly, and after seeing the demonstration of the old eleven, even Li Shimin had to admit that the Tianzhu numbers were really simple and convenient to use, and the calculation was even easier!

Now listening to Huang Ren talk about what percentage or something, the emperor is even more sure of Lao Eleven's idea - that kid just likes this Tianzhu number, and he wants more people to learn this thing.

It's just that this Tianzhu number is really worth it?

Just when Li Shimin was slightly contemplating and pondering, and Huang Ren and Ma Yuan were a little confused, Lu Guogong next to him suddenly smiled and said: "Your Majesty, this Tianzhu digital minister also knows a little, it is indeed easy to use, just to start learning from scratch, it is really difficult for the minister." ”

"Oh? Cheng Aiqing also learned this Tianzhu number? ”

Li Shimin's eyes lit up when he heard this, and he looked at Cheng Zhijie beside him with some surprise.

"After learning the beginning, it's no problem to play cards."

Grinning, Cheng Zhi nodded and said, "But the things in the back are a bit difficult, and the minister really doesn't have the mind and time." However, the minister asked Erlang and the bookkeepers at home to learn, and wanted to wait for them to learn and see how it worked. ”

"Erlang ......"

With his eyes narrowing slightly, Li Shimin nodded noncommittally.

Cheng Fu Erlang is his son-in-law, the emperor naturally will not be unclear about the virtue of that kid, it can only be said that it is a middle-class posture, presumably it will not be too easy to learn Tianzhu numbers. But what surprised him was that Cheng Zhijie, an old man, would let his son learn this mathematics, and even let the family's account office follow suit?

Brushing the long beard under his chin, Lao Li was a little moved.

If his feeling about Lao Eleven is that his mouth is hairless and he can't do things well, so he doesn't care much about Tianzhu's numbers because of this, then Cheng Zhijie's actions of this old man can't be ignored by the emperor.

Maybe in the eyes of many people, Lu Guogong is a martial artist, but Li Shimin, who has been with him for more than ten years, knows very well in his heart that this guy is really better than a monkey! If nothing else, let's just say that the two medical workers under the hands of the two old eleven in front of him will be the first to ...... Well, isn't the place where the test is Cheng Zhijie?

If the math and Tianzhu numbers are really useless, this old boy will let his own Erlang and the bookkeepers learn it?

Anyway, if you want to say that Cheng Zhijie is to befriend King Han, you don't believe it if you kill Li Shimin!

He is a founding hero, a dignified prince, even if he sees the prince of the current dynasty, at most he just makes a salute, so he can be afraid of the old eleven and an idle king? I'm afraid that except for the crown prince, his other sons may not be able to make Cheng Zhijie so good...... Or even flattering?

So after thinking about it for a while, Li Shimin had to face up to the Tianzhu numbers and those math books that Lao Eleven always talked about again.

But now is not the time to think about that, the emperor raised his eyebrows after a moment, "How long have you two been under Lu Guogong?" How many people have been treated in total? How many survived and how many were crippled? Now tell me about ......"
