When Xu Du saw Nurhachi and Li Yongfang, outside the back door of the Li Mansion at this time, Liu Zongmin, who was dressed as a businessman, learned three bird calls after seeing that there was no one around, and then looked at the back door.

It didn't take long for the head of a good-looking girl to poke out from the back door of the Li Mansion.

"Don't be nervous! Just do the same as before. ”

Liu Zongmin nodded.

"Hmm."

This Xiao'e nodded.

Liu Zongmin then asked: "Why are there so many soldiers outside?" ”

"I heard that it was the Great Khan of Jiannu who came to the palace."

Xiao'e replied.

"Oops!"

Liu Zongmin sighed in his heart, but he still forced himself to calm down and asked Xiao'e: "Are you afraid?" ”

Xiao'e shook her head and said with a resolute expression: "Don't be afraid!" They killed my father, and I'm willing to kill him for you, even if it's because of it! ”

Saying that, Xiao'e smiled: "So I can see my father and mother earlier." ”

"You're a poor man, too."

Liu Zongmin took out a small steel cylinder first, opened the gold valve on the small cylinder, threw it in the direction of the downdraft, and said to Xiao'e: "I'll demonstrate it again, open it as I just did, and then throw it out, you know?" ”

Xiao'e nodded: "I have remembered it for a long time!" ”

"Then I still have to demonstrate it again, I'm afraid you'll forget it in a hurry!"

Then, Liu Zongmin took out a transparent glass mask from the blanket again, and said to Xiao'e: "You come here, I'll put this on for you, and then you take a few bottles I gave you and open them and throw them in the front yard, don't worry about their guards taking you down, as soon as the gas in this bottle comes out, in a short time, they will lose their mobility." ”

"I remember!"

Xiao'e agreed.

Liu Zongmin put the glass mask on Xiao'e's head, and because he smelled the fragrant smell of honey locusts coming from Xiao'e's body, he instructed again: "If the glass mask is taken away, cover your mouth and nose first, but find a place with water, wet your clothes and then cover your mouth and nose." ”

"Hmm."

Xiao'e agreed, and then went home.

And Liu Zongmin also put on a glass mask and ran directly to the front yard, and threw a steel cylinder while the guards guarding the front yard were not paying attention.

A guard saw that the steel bottle thrown in front of him was steaming yellow-green, and he only felt strange, so he couldn't help but pick it up, and said to his companion: "This bottle is golden, presumably coated with gold dust, this bottle is undoubtedly a treasure, who suddenly dropped it here?!" What is the green gas? ”

Immediately afterward, the guard coughed violently, and he suddenly realized that the yellow-green gas was very pungent.

Not long after, the guard felt that his eyes were extremely uncomfortable, and his skin was extremely painful, and then he fell to the ground and howled.

His companion heard that it was the baby who was looking over, and he was also stimulated by this gas, and coughed one after another by grabbing his chest and leaning against the wall, and for a while he was like a blind man, and he could only watch a person with an unclear face and a clear figure coming here, still throwing something, so that there was more and more yellow-green gas here, as if the whole world was dyed yellow-green.

Xiao'e secretly took a shortcut to the front yard here, and threw the cylinder opening valve given by Liu Zongmin in the front yard.

"There are assassins!"

Seeing him, Nurhachi's guards hurriedly shouted, and was drawing his knife and running towards Xiao'e, when he felt that his lungs were about to explode, and coughed violently.

Seeing this, Xiao'e hurriedly opened more cylinders and threw them into the front yard, and for a while, in the entire relatively closed front yard, the yellow-green gas became more and more dense, and the people brought by Nurhachi and Li Yongfang himself were coughing and screaming in the yard.

……

The words are divided into two ends.

Before Liu Zongmin saw Xiao'e, Xu Du had just seen Nurhachi and Li Yongfang, and after saluting, Li Yongfang looked at Li Shutai and said, "What is the box you are holding?" ”

Li Shutai replied: "It is a gift from Xu Qianhu to his father. ”

"Gifts?"

Nurhachi asked first.

Xu Du pretended to be indifferent and said: "That's right! This is the industrial product produced by the Xishan Industrial Division of the Military Governor's Mansion of the Ming Dynasty, called the fairy spirit, which can make people invigorate when smelling, and can help boost the morale of soldiers when fighting. ”

When Nurhachi heard this, he wondered: "Is there something that can boost morale?" ”

Xu Du nodded: "Just as the smell of a woman's body fragrance makes me feel excited, their industrial department also got inspiration from this and developed this spice." ”

fo

"The Department of Industry, and also made spices to boost morale, this Xishan is really amazing, your emperor and the students of the Wubei Academy were able to defeat my three Baylor's banner soldiers in Xishan last time, didn't they rely on these strange skills?"

Nurhachi asked.

Xu Du replied: "Naturally, there is a relationship. ”

After hearing this, Nurhachi hurriedly said: "Open the gift!" ”

"Wow!"

Li Shutai hurriedly opened the gift box.

Then, Nurhachi and Li Yongfang saw a delicate steel bottle lying in a brocade box.

Li Yongfang hurriedly picked it up and handed it to Nurhachi.

Nurha equatored: "This steel is used to make bottles, it is really a terrible thing." ”

So saying, Nurhachi asked, "Where is the scent?" ”

Xu Du arched his hand and said: "Please give it to the next and let it be demonstrated for the Great Khan." ”

Nurhachi was not worried that Xu Du would be able to deal with himself with the cylinder in front of him, so he handed the cylinder to Xu Du.

Xu Du directly knocked on the valve.

Boom!

When a stream of yellow-green gas rushed out, Xu Du immediately aimed the cylinder at Nurhachi.

Nurhachi coughed violently.

When Li Yongfang and Li Shutai were still confused, Xu Du hurriedly covered his mouth and nose, and also aimed the mouth of the cylinder at Li Yongfang, Li Shutai and the others in the room.

The men all coughed, and Nurhachi gasped for breath.

Xu Du hurriedly poured tea on his sleeve, and then covered his mouth and nose with his wet sleeves, and at this time, there were also guards outside who broke in when they saw this, but as soon as they came in, they were also choked.

Xu Du took advantage of this to take the sword of a personal guard, ready to kill Nurhachi and Li Yongfang at any time.

But at this time, there was also movement outside, and this movement was made by Xiao'e.

Therefore, Xu Du simply killed the other guards and Li Shutai with a knife, and ran out and opened the gate.

As soon as the door opened, Liu Zongmin threw a glass mask to Xu Du, and he himself rushed in with other members of the hoe team and killed the other guards in the courtyard.

Xu Du then followed, took Liu Zongmin to Li Yongfang and Nurhachi, pointed to an obese old man who was still screaming, and said, "This person is Li Yongfang." ”

Liu Zongmin hurriedly ordered someone to carry Li Yongfang away.

And then, Xu Du pointed to a thin black old man and said, "He is Nurhachi, take him away too!" ”

Nurhachi's physical function has declined this year, and he is much thinner than before, according to the development of the original history, he will die violently after the conquest of Mongolia in the second half of the sixth year of the Apocalypse, so now he is not as good as Li Yongfang in terms of physique.

Nurhachi now felt only a sharp pain in his chest like a tear, and he had difficulty breathing, and he was exhausted, so he had to let these people take them away.

"Get in the car!"

Soon, Nurhachi and Li Yongfang were helped up to the city and rushed out of Shenyang.

The gate they had arrived at had been taken by the other members of the hoe team, and they had also used poison gas.

After Zhang Gui set up the Industrial Department in Xishan, he asked Song Yingxing and others to study and prepare the "three acids and two alkalis" that symbolize the foundation of the chemical industry, and the hydrochloric acid, which should have appeared eight years later in history, appeared in advance under his influence, and thus made the poisonous gas such as chlorine gas can be prepared in Xishan through the natural mineral pyromanganese.

Originally, the preparation of chlorine gas from pyromanganese ore and hydrochloric acid did not appear until the eighteenth century, but Zhang Gui now let him appear in Xishan in advance.

And after Zhang Gui asked the Xishan Industrial Division to prepare chlorine gas, the first thing that came to mind was to use it to deal with the enemy, so as to shorten the difficulty of dealing with the enemy.

This time, Li Yongfang, captured by the hoeing team of the West Factory, also used chlorine prepared by the Industrial Division.

As for the glass mirror mask, it is a gas mask developed by the Xishan Industrial Division itself, which contains charcoal particles boiled with soda ash.

Of course, these things are very expensive, and the cost of chlorine preparation alone is not comparable to the electrolysis process in later generations.

Even the bottle containing chlorine gas and the mouth of the bottle are coated with a layer of gold.

Therefore, at present, it can only be used when the West Plant conducts a special operation, and it cannot be used for large-scale military operations.

No further ado.

After Xu Du and Liu Zongmin escorted Nurhachi and Li Yongfang out of the city, they immediately drove a new carriage with rolling bearings to southern Liaoning.

The people of their hoe team had already contacted Zhou Yuji in advance to send cavalry to meet them.

Now, what they need to ensure is that Li Yongfang and Nurhachi do not die directly from inhaling too much chlorine.

Because it was too cheap to let these two people die directly.

After all, both of them owe a lot of blood debt to the Han people in Liaodi.

"Xu Qianhu, do you give them breath, or do I go first?"

Liu Zongmin asked embarrassedly.

"Uncle Guo said that only in this way can they be saved, and there is no other way, so, one for each person! It's a turn to come! ”

"Ahh

Xu Du had already slammed into Nurhachi's mouth without hesitation.

Nurhachi's eyes widened: "The insult to Ben Khan is too great! ”
