The simple-minded Hua Yelangjun was easily coaxed by Li Yi and Ding Yin, and agreed to work obediently.

However, because he didn't hear Qin Nuan call "uncle", he still walked up to Qin Nuan again, and said with a smile: "Ah Nuan, call uncle quickly!"

Qin Nuan: "......"

Li Yi got the small bottle of medicine in Huaye, and was in a good mood, so he took the small azure porcelain bottle in his hand and looked at it, and asked, "Is there an antidote? How long does this medicine work?"

Hua Ye coaxed Qin Nuan for a long time but didn't succeed in becoming an uncle, a little stunned, and replied: "There is no antidote." It is said that the effect of the drug begins to slow down after one hour, and it takes two hours to fully recover. However, I haven't tried it, it's about two people, you can try one!"

Ding Yin said with a smile: "Where did you get this medicine, there is nowhere to buy it with piles of gold!"

Hua Ye said: "Didn't you trick me into going to Tianshan at the end of last year, when I was passing through Liangzhou, a Tianzhu monk wanted to trick me into being his apprentice, I saw that he was uneasy and kind, so he stole all his things." Later, he came to trouble me, but he couldn't beat my sister, but was beaten half to death by my sister, and this thing is the thief's bald thing. ”

Li Yi immediately asked, "What else is on that monk?"

Hua Ye immediately looked disdainful: "It's mostly some improper medicine! That monk wants to go to Chang'an, sell it to those nobles, and make a lot of money!"

Improper medicine, monks from India...... Qin Nuan immediately guessed what kind of medicine it was, there was a famous thing called "Indian Divine Oil" in later generations.

Li Yi asked, "Where is this monk now? Have you got this prescription?"

Hua Ye pouted: "This kind of medicine, the prescription is naturally to ask, but unfortunately, most of them are materials that are only available in Tianzhu! Some ingredients are very rare even in Tianzhu! It is also a cart of herbs to be refined! The monk was beaten half to death and fled back to the Western Regions." ”

When Qin Nuan heard them say this, he realized that martial arts novels were really deceitful, sweat medicine, seeing blood to seal his throat or something, either he had to drink it into his stomach or enter his blood, so that a strong anesthetic that could work if it entered a little bit through the air from the respiratory tract, it was really not easy to have it in this era!

As for the smoke, incense or something, it must be in a small space, relying on reaching a certain concentration, relying on people who are defenseless, such as resting or sleeping or something, to work, or a little stronger, directly cover people's mouths and noses with a drug-soaked handkerchief......

If it can work if it is scattered under the empty sky, then it is really as Ding Yin said, what kind of battle is there to fight, just fight the alchemy technique, and spill a bunch of them in the wind......

Chemical warfare was only possible by the end of the nineteenth century, when industry was able to produce large quantities of toxic substances.

Qin Nuan suddenly thought of a famous case of chemical warfare in ancient times: in the Peloponnesian War in the 5th century BC, the Spartans used sulfur to burn to produce toxic smoke to suffocate the opposing side......

Qin Nuan thought of it and immediately said: "You can use sulfur!"

Sulfur combustion can produce a large number of toxic gases, which can strongly irritate people's eyes and respiratory tract, and high concentration inhalation can make people die due to edema of the respiratory tract and lungs, and even suffocate quickly because of glottal spasm.

Li Yi's eyes flashed with surprise, and then her fingers knocked on the desk to think, and after a while, she said coldly: "People will run!"

Qin Nuan was immediately struck......

Yes, people will retreat when they see the poisonous smoke, and when the smoke clears, they will run back and continue to attack the city!

Because the people are besieging the city, and they are defending the city, but they are the side that squats on the city wall and cannot run.

This is best for the besieging side.

The Spartans and Athenians fought to the death on the peninsula and in the Aegean Sea for so many years that the "Brimstone War" was just a small episode......

Thinking of the Aegean Sea, Qin Nuan's heart flashed with inspiration-

Boat!

"It can be used on a ship!" Qin Nuan said hurriedly: "Isn't it the ship of the traitor that we need to be vigilant about the most!"

The lesson of the loss of Hangzhou is just around the corner, and everyone is worried that a group of big ships of rebels suddenly appeared on the river, and then rushed down countless soldiers......

When Li Yi heard this, he jumped up as soon as he slapped the case, "Ah Nuan! you can really surprise me at any time!"

Qin Nuan knew that so many big ships of the rebels had always been the biggest problem in Li Yi's heart.

Although everyone knows that it is a good way to burn a ship with fire, the two words "fire attack" -- cut! Is it so easy? Where is it so easy to burn someone's ship!

If it's so easy to burn, why train the navy!

This is a medieval era without thermal weapons.

It was only in the Song Dynasty that there was a gunpowder workshop, and only then did it research and manufacture weapons such as gunpowder arrows with combustion performance, or sky-shattering thunderbolt cannons with strong explosive performance.

Qin Nuan originally didn't expect that she would encounter a war, and she also felt that the thermal weapon war was too cruel and should not be let the world know about the thermal weapon war early.

However, now that it has reached this point, there is no way back, it will be sooner sooner, and it will not be two hundred years earlier anyway.

Besides, cold weapon warfare is as cruel as it gets.

So Qin Nuan continued: "Sulfur burning can produce a large amount of toxic smoke, sulfur, saltpeter and toner are mixed together, and the flame is very large after ignition, if it is contained in a jar, or the space is small, it will explode and hurt people!"

Hua Ye touched his chin and said: "I remember that in "Fan Zi Yeran", it was said that sulfur and realgar saltpeter were combined with honey, and the result was a flame, burning hands and houses." ”

Then he thought about it for a while, and added: "Sun Lao Immortal also said in the Danjing Inner Sulfur Method: sulfur and saltpeter are two taels each, ground into powder, and put in a silver pot or sand jar. Dig a pit and put pots in the pit and on the ground, and fill it with earth on all sides. Light the three soap horns that have not been eaten by insects, then put them in the pot and set the sulfur and saltpeter into a fireworks. When the fireworks can't be burned, stir-fry the charcoal again, fry until the charcoal is gone, then anneal, take the mixture before it cools, and ambush the fire. ”

The "Sun Lao Immortal" that Hua Ye said is the medicine king Sun Simiao.

It's just that Sun Simiao's approach here is to think about how to control the fireworks and prevent them from exploding, and his purpose is to "ambush the fire".

Li Yixi said: "It seems that this one is mixed and burned, and it can really cause flames! I immediately asked someone to try it!"

Qin Nuan suddenly felt a little weak, is it too late to study this now?

Li Yi really asked: "Ah Nuan, why didn't you say these things earlier!"

Qin Nuan lowered his head and said guiltily: "Before, I didn't think of it, but I just remembered it when I talked about sulfur. ”

Li Yi just asked casually, but he didn't take it to heart, but went to the study to arrange manpower in a hurry, of course, this is the first-level top secret of the palace, Li Yi specially told Hua Ye and Qin Nuan, never say half a word when you leave this room.

However, after Qin Nuan walked out of Li Yi's study, he suddenly thought of a question, and suddenly broke out in a cold sweat, and couldn't help but tremble lightly in the hot summer:

The first emperor Li Hong, Qin Nuan deduced from various indications that he was also reborn, and he became the sad prince of Li Hong. Originally, in the historical trajectory, he was the eldest son of Her Majesty the Great Holy Empress who was deposed, but he succeeded in conquering the heart of his great mother, making the Iron Empress a true loving mother, and he succeeded in becoming the emperor himself, and brought many changes.

It is estimated that he was reborn by relying on the reincarnation jade ring left in the Li family's royal family.

However, why didn't His Majesty Li Hong come up with gunpowder weapons? He could say things like "a strong youth makes the country strong," and it was impossible for him not to know gunpowder.

Why? Why didn't he get gunpowder?

He is an emperor, during his reign, the empire also engaged in various wars with the surrounding nomads, why didn't he ask someone to study gunpowder weapons, if there were gunpowder weapons, wouldn't it be much easier for the Tang Empire to conquer those alien races around it?

Why is His Majesty Li Hong so low-key?

There must be a reason for this!

Qin Nuan found from the revised version of the "Anshi Rebellion" in front of him that the changed history turned a corner, and it seemed that he was still coming back......

Qin Nuan was inexplicably scared.

Could it be that Li Hong was scrupling about something, so he didn't dare to go too out of line?

The Li royal family studied the jade ring for many years, and finally didn't understand how to use it, and finally passed it directly to the prince every time to wear it, which led to Li Hong's rebirth.

But they didn't figure it out, it doesn't mean that there are no research results at all, Li Hong must know much more secrets about the reincarnation jade ring than Qin Nuan.

Qin Nuan knew nothing except that he knew that he was alive because of the jade ring.

In addition, she also knew that this jade ring was probably snatched by her maternal grandmother's ancestor from Emperor Gaozu of the Li family.

My grandmother's ancestors were enemies of the Li royal family......

Under the summer sun, Qin Nuan was covered in a cold sweat and soaked his clothes-
