On the side of the earth blast furnace, it was handed over to Yu Haozhong to be responsible.

As a foreman-level figure, his hands-on ability is beyond doubt.

Civil engineering was at his fingertips.

And after Pei Yun arranged for someone to bring him bricks and cement.

With the ability of one person, he built the area of the earthen blast furnace into a large-scale workshop.

The location is in a remote area at the foot of the mountain.

No one passed by this side.

Only a small stream flows down from the mountain, forming a small lake not far away.

This means that there is no need to worry about water supply.

And the small stream has the added benefit that it is a branch of the river in the mountains.

The rivers in the mountains can be used to transport coal.

And this small stream can also transport things down from the mountains.

This makes it easy to obtain a variety of materials.

Pei Yun is planning to make this a secret small base.

The scale doesn't need to be large.

Too big is not good for hiding.

It's not big, but its importance goes without saying.

If allowed, if necessary, it would become an arsenal.

Of course, this is just an idea, and it is not that simple to implement.

You can't do it all by yourself.

Now Nanshan Village has the most talent for striking iron, and there is only one Niu Li.

But Niu Li obviously can't build weapons.

Rely on yourself to support the construction of weapons in an arsenal......

That's still forget it, in the end, you have to die of exhaustion.

Therefore, without manpower, everything is free to talk about.

Just like now, the earth blast furnace has not been officially started.

At this point, this place is no different from abandonment.

The arsenal is just an idea, and it is not certain whether it can really be implemented.

You must know that large-scale private weapons are a major crime of killing heads.

Unless you have some ambitions, you don't want to take this step.

So the basis on which this idea can be built is allowed, if necessary.

Near the foot of the mountain, there is a cave, which is not small, and it has become a warehouse.

In the cave, there were coal, iron ore, and some weapons that were considered tattered in Pei Yun's eyes......

These are the materials used to make weapons, and they are quietly staying in the cave for the time being.

Because the cave is large enough, it becomes a temporary cage.

According to Pei Yun's explanation, Master Fan and the official were both imprisoned here.

When they were brought here, they were hooded sacks all the time, so they didn't know where they were.

Actually, Pei Yun was curious that the Qin Niangzi Army could capture them all alive.

When Pei Yun asked what had happened, he was pleasantly surprised.

Things have to start with a Qin Niangzi Army.

She found a flower in the mountains that she had never seen before.

This flower grew beautifully, but it was different from other flowers, so she picked a lot of them and put them at the head of her bed as an appreciation.

Unexpectedly, she has been suffering from sleeping disorder since then.

And by chance, she found that her sleeping sickness was related to the flowers she picked at the end of her bed.

The flower was later proven to be toxic.

After finding the culprit, her sleeping sickness was cured.

But that's not all.

She had a whim.

This flower is poisonous, so can it be used for another purpose?

In the end, she smeared the flower on the bolts.

While hunting, she discovers that crossbow arrows smeared with flowers make prey move abnormally.

This is the key to really being able to catch Master Fan and the official messenger alive, at that time, Qin Niangzi's military used such crossbow arrows.

And after Pei Yun got to know the flower, a name was about to come out.

"It's a mandala flower."

Mandala, Sanskrit, mandala flower, also known as the horn of angels and devils.

Mandala flowers, are poisonous.

Mandala flowers are almost completely poisonous.

From the root to the stem to the fruit to the seed, it is very toxic.

Seeds, in particular, can generally poison a horse in a short period of time.

Once a certain part of the mandala flower is accidentally eaten, it is generally not more than half an hour, and the poisoned person will have a series of poisoning symptoms.

The poisoner will be very excited, and then he will have a headache and hallucinations.

In the final stage, the poisoned person will have severe phenomena such as spasms, and eventually die in a coma.

Therefore, although the mandala flower is beautiful, it should be avoided.

However, it is such a poisonous flower, and it also has an effect that cannot be ignored, and if it is used properly, it is also a drug.

Mandala flowers, its leaves, flowers, and seeds can be used in medicine.

Its efficacy.

First, anesthesia and analgesic and antispasmodic effects.

The second is to improve sleep, mashed leaves, can help people fall asleep as soon as possible.

Third, for the treatment of rheumatism and arthritis, it is effective to use fresh leaves, flowers and seeds to pound and apply to the relevant parts of the area.

Among them, the anesthetic effect of the mandala flower can be said to be miraculous.

You know, as far as modern surgery is concerned, anesthesia is indispensable.

And when it comes to the earliest anesthesia, it is the famous Hua Tuo hemp boiling.

The main ingredient of hemp boiling powder is the mandala flower.

Legend has it that Hua Tuo's son Fei'er died of eating mandala flowers by mistake, and in order to commemorate his son, Hua Tuo named the anesthetic prescription prepared with mandala flowers as Ma Boiling San.

And the historical position of hemp boiling in the medical world, there is a passage that says.

There is such a doctor, who traveled abroad to study when he was a teenager and practiced medicine all over the world.

When the epidemic was epidemic, he traveled around to treat the common people, regardless of pay.

In order to alleviate the pain of patients, on the basis of decades of medical experience, he tried and tested repeatedly to make "Ma Boiling Powder".

He was the first to use general anesthesia to perform surgery, and was respected as the "originator of surgery" by later generations.

This person's name is Hua Tuo.

How hemp boiling powder is prepared, Pei Yun knows.

The main material is mandala flowers,

It is followed by raw grass black, Chuanxiong, angelica, angelica, and fried southern star......

Among them, mandala flowers account for the largest proportion.

Compared with other medicinal herbs, mandala flowers are rare.

In fact, there are many places where mandala flowers grow.

Fields, ditches, roadsides, river banks, and hillsides are all places where mandala flowers grow.

But for normal people, the mandala flower is a poison.

And that's what happened.

In common places such as fields, ditches, roadsides, and river banks, the mandala flower has long been extinct by the ancestors.

Mandala flowers can only be found on sparsely populated hillsides.

I didn't expect to be able to capture Master Fan and the official messenger alive, and it was a mandala flower that made a miraculous achievement.

This is also good news for myself.

In the future, I will not worry about the use of mandala flowers.

Of course, it is difficult to find mandala flowers during the winter season.

It is a miracle to be able to find mandala flowers in winter, and the minimum temperature for growing them is 1 degree Celsius.

In order to smear the crossbow arrows with poison, all the mandala flowers in the mountains were picked.
