The setting sun is like blood, and the red clouds are everywhere in the sky.

At the most beautiful dusk, a figure suddenly appeared in the vast world.

Li Yao galloped on his horse, like a meteor.

After pretending to be a soft girl for a few days, she was almost ruined.

But this feeling of changing the historical ending and achieving the goal as you wish is great!

In this action, Li Yao never told anyone except that she took the initiative to come to Zhang Hu and Li Tong and the other two knew that they would assassinate He Ruohuaikuo.

No one around her could know her "refining medicine" and "cultivation" a few days ago, as well as the real purpose of participating in the "Sanyin Society" competition.

Li Yao asked himself more than once: "Do you want to change the whole world?"

And now the answer is becoming clearer and clearer.

That is "thinking", thinking about it is almost crazy!

Once a person comes to the world, desire will arise, and desire is a breeding ground for ambition.

Unexpectedly traveling through time and space to come to a wonderful world, who would give up the opportunity to perform on the historical stage?

Liu Xin, the author of "The Mystery of Heaven", would not give up, but he only had ambitions and had no ability, and the result was all in vain.

Li Yao is different. She has an identity that bothers herself but is extremely unique, has a very comprehensive knowledge and inhuman ability, and has the power to change history by herself. Even if she only has a little desire, it will expand more and more, expanding to a point that even she herself cannot control.

In Li Yao's mind, the 15,000 taels of gold was just the start-up capital for her to realize her ambitions. The structure of Shazhou and Guazhou is too small, and at most it can only be regarded as a small fulcrum for her to expand her ambitions.

But no matter how great ambitions are, they must start with small things.

Li Yao felt that he was no exception.

According to the original history, Zhang Hu and Li Tong, the representatives of the Central Plains gentry in Dunhuang, also made He Ruohuaikuo, but they did it so ugly that Li Yao had obsessive-compulsive disorder and felt that he was very necessary to get involved.

Therefore, Li Yao would help others, solve their problems cleanly and beautifully, and prepare a few more bricks for their personal forces that they have not yet formed.

As for Li Yao's entire plan to help others, it naturally started with making tools to solve problems.

Initially, Li Yao mixed the "green alum oil" refined through the Danjiao copper furnace and heated it to make a primitive dilute hydrochloric acid, and at the same time asked Xuan'er and Hui'er to ground the aconite she bought from the medicine shop into powder. Then, in a certain proportion, poured the dilute hydrochloric acid and aconite powder into a small clay pot, stirred it evenly with a ceramic rod, and then sealed the clay pot and buried it underground.

Then, Li Yao took out a manual drill bought from the street market and practiced turning holes on ordinary bamboo materials.

This kind of drilling is said to be an ancient tool that originated in the Warring States Period. It can drill small thin holes as thin as silk in the dianthus and wood. It has not been completely replaced by electric drills until the 21st century. It is still a magical tool in the hands of some traditional craftsmen.

When he was more useful, Li Yao took out a single-tube bamboo flute called "recording flute" at this time, fixed it vertically with a clamp, and then started to drill holes from one end of the flute tube.

Although the thickness of the pipe wall of this bamboo flute is at least eight millimeters, and the diameter of the hole that Li Yao turns is enough to be three millimeters, after all, drilling holes in the cross-section of the bamboo tube can easily cause the pipe wall to rupture. Due to the maximum drilling depth of the pull drill, the holes can only be rotated at the opposite positions at both ends, which is easy to lose a slight loss.

Fortunately, Li Yao had prepared for a long time. After scrapping several expensive high-quality bamboo flutes, she finally successfully drilled out three holes in one bamboo flute.

So, a poison needle tool "Blowing the Flute" that imitated the ninjas who traveled at home in the Edo period of the island country, and played murderously.

However, although the transformation of the "arrow blowing flute" is very difficult, the key to completing a one-hit kill is to rely on the power of "arrow blowing".

For this, perhaps the most outstanding ninja in the history of the island country would be at a disadvantage in front of Li Yao.

In the Tang Dynasty, cold drawing technology was not yet born. To produce iron wire, you had to burn the iron bars red first and then draw them into thread shapes. The iron wire produced in this way is often thicker, so the thinner needles in this era are the more expensive.

However, the needles that Li Yao needed were not used for embroidery. The ones she taught An Hongyu were made of iron needles with grooves at the end of the needle, which were two inches long and a maximum diameter of about one millimeter.

Of course, pure iron needles cannot be blown far. Anyone who knows how to blow arrows knows that the thrust at the tail of the needle determines the effective range of the poison needle.

In order to try to kill people invisibly, Li Yao naturally could not use materials that were easily visible to the naked eye. So she caught and killed many insects with transparent fins and screened them. As a result, she found that the soft wings of the cone-headed locust just met the requirements, and then used scissors and paste to make the transparent soft wings on her body into a trumpet-shaped "cone tail".

Before shooting, you must first stick the tip of the "cone tail wing" into the groove of the iron needle tail in advance, and then carefully stuff it into the hole of the bamboo flute tube wall. Then when the iron needle is blown away from the bamboo flute, the "cone tail wing" will fall off because it cannot withstand the air resistance. After repeated debugging, Li Yao only needs to blow it a little hard, and the iron needle can be penetrated into the wooden board twenty meters away and cannot be pulled out.

After the pottery jar was buried for several hours, Li Yao dug it out of the ground, poured it into the pottery tray, and naturally evaporated it to powder, and then obtained the coarse aconitine.

Aconitine is known as the "king of poisons", and even in the later generations of medical science, there is no special antidote.

If a man weighing 70 kilograms is poisoned through a wound, two hundred milligrams of arsenic, one hundred milligrams of potassium cyanide, and only two milligrams of aconitine.

The most terrifying thing about aconitine is not only the extremely low lethal amount, but also its extremely fast lethality.

Because its toxicity can be circulated through the blood, causing ventricular fibrillation, and can kill the poisoned person in just two or three seconds, there is no time to rescue him.

In addition, aconitine was not detectable before the end of the 19th century. "Aconitine" and the chronic poison of the Renaissance "diamond", one fast and one slow, were called the most infamous poison in European history.

In later China, due to improper handling and lack of common sense, there were accidental ingestion and deaths every year.

Even if the skin seeps into the aconitine, it will suffer certain damage. However, if it accidentally touches the wound or the mouth, nose, eyes and ears, it will naturally die immediately.

Therefore, poisoning the iron needle has become an extremely dangerous operational process.

Just in case, Li Yao put on gloves made of fine linen cloth, moistened the first half of the iron needle slightly, and then wrapped it with a layer of aconitine. After it was dried, he stuffed the poison needles into the three holes of the flute tube one by one.

Next, in order to ensure the hit rate, Li Yao almost killed all the nocturnal animals in the courtyard the night before the opening of the Fanyin Society, and then stopped until he thought he had reached the level of 100.

Finally, on the stage of the Fanyin Society, Li Yao observed carefully from a high place and found that although He Ruohuaigu had heavy armor in his robe, his head, neck, armpit, inner upper arm, inner thigh, and back knees were not protected. After some consideration, Li Yao listed the armpit as the target site, the inner arm, inner thigh, and back knees as the secondary attack site. The poison needles that attacked the head and neck were too easy to be seen in various senses, so they were completely excluded.

Li Yao was waiting for the opportunity, but when the blowing was about to end, she seized an excellent opportunity.

Seeing He Ruohuaigu raise his hand inexplicably, Li Yao immediately gave up playing the notes without thinking and blew a poisonous needle instead. The two were only a few feet apart, and the poisonous needle naturally penetrated into He Ruohuaigu's soft flesh under his armpits with extremely accurate accuracy, with almost no trace of it.

Later, at the critical moment of Zhang Hu's life and death, she blew the poison needle into Pu Naisheng's knee in a similar way.

Therefore, when Zhang Hu swung the dead head, Pu Naisheng was actually a dead person.
Chapter completed!
