She remembers.

In ancient times, in order to seek the method of alchemy and immortality, gunpowder was accidentally invented.

Because the alchemy furnace produces purple smoke, the alchemy old way must control the heat in order to find the proportional fusion.

Su Liuyu thought of the flint of the Great Zhou.

I'm afraid it's also an accidental discovery.

If she gets it out, not to mention fighting, if the Xuanwu Army doesn't recognize the Tiger Talisman at that time, she Dawei will also have the power of an enemy!

It's just that......

For this thing, Su Liuyu was a little stunned.

She was killed.

"Have you seen enough?"

A deep, cold voice sounded.

Like the sky above the snow-capped mountain, the wind blows through the jade tree of Qionglou and makes a variety of sounds.

Su Liuyu came back to her senses.

looked at the trail leader leaning on the bamboo chair under the summer tree.

The hat was gently flicked, dressed in white, and the slender hand held a banana fan that blew the stove, and if you looked closely, you could see the pale green veins floating on the back of the white hand.

Su Liuyu took a step back.

It's a bit cowardly.

"I'm here to find Yunyi."

She steadied her tone.

"Is he in the temple?"

"Hmm."

As soon as the syllables fell, Su Liuyu slipped away.

I'm scared to death.

This kid started a fire, but it was fatal.

It's better to stay away.

Under the summer tree, Yun Xuzi opened her eyes, looked at her hasty back, snorted, and continued to lean on the bamboo chair to sleep.

"Out of breath."

Su Liuyu felt bitter in her heart, and pulled Yun Ya'er to complain.

"Your brother's temper is too bad." She poured a sip of tea, and then she was a little happy: "I'm scared to death." ”

Yun Ya'er was distributing medicinal materials, and when she looked at her like this, she also snorted.

"Out of breath."

“......”

Su Liuyu leaned over, saw that he was busy packing medicine, and asked.

"Yunyi, are you sick?"

She picked up the herbs and sniffed them, and was slapped down by Yun Ya'er with one hand.

"Don't touch it, it's poisonous."

“......”

Yun Ya'er took out a silk handkerchief and wiped her hands carefully, and then said:

"Brother has recently specialized in alchemy, don't mess with him."

Su Liuyu looked into the hall.

It was found that in addition to a lot of medicinal materials on the bookcase, there were also many books.

You must know that Yunya'er is a good doctor, and his medical skills are all memorized in his mind, where he needs to read what books.

It seemed that seeing her doubts, Yun Ya'er explained.

"I have always been good at prescribing prescriptions and taking medicines, but the master is quite proficient in the art of alchemy, the palace of eternal life, the medical skills are inadequate, and my brother can't bear the defeat of alchemy, so I hereby come to me to discuss the alchemy method in the master's book."

I see.

Xuanyou is a real person, she has heard of it.

The expensive life-saving elixir she ate seemed to have been refined by this Dao master.

"What is this?"

Su Liuyu swept to a corner of the bookshelf behind the bookcase and found a dusty box.

The lock is peculiar, and the material looks tough and complex.

How was it made?

Yun Ya'er frowned slightly.

"The Secret Treasure of the Palace of Eternal Life."

What the!

Su Liuyu's eyes widened.

"This secret treasure is placed here?"

It's too casual.

"What's in there?"

Yun Ya'er said lightly: "I don't know." ”

"Will it be a title deed, a house deed, or a treasure map?"

Maybe it's still the savings of the Hall of Eternal Life for a hundred years!

The more Su Liuyu thought about it, the more it made sense.

After all, in her opinion, only the silver needed to be locked.

Insurance!

Yun Ya'er didn't want to pay attention to her.

His hand to collect the herbs was slightly sluggish, and he remembered some old things.

Master came to Dawei for this thing.

Otherwise, it wouldn't ......

He put away his thoughts, wrapped the herbs, and rolled up his sleeves again, revealing his thin arms.

"Eat fish?"

"Hmm."

Su Liuyu is still studying this lock, and she always feels that there is a treasure here.

It's just that.

In addition to this box, she has one more important thing to study as soon as possible.

For example, stealing Yun Xuzi's alchemy pill.

The big flicker has always been the same.

had dinner with Yun Xuzi, and waited until the dead of night to pull Yun Ya'er out to steal things.

"I want to make a big guy." She tugged at the corner of Yun Ya'er's sleeve, and her eyes were excited: "The power is very strong." ”

“......”

Yun Ya'er wanted to beat her.

Under the moonlight, the young man squatted in front of the Dan furnace, dressed in white like snow, but his face was a little stinky.

"Build what?"

He asked patiently.

"You'll find out later."

Regarding the production of the "Fu Huo Alum Method", it is quite simple.

If it was used for ordnance, the earliest was the flint cannon.

She remembered a statement.

"The ballista is used as the gate of the formation, and the bed crossbow is placed on it, the arrow is as big as a chisel, one arrow can shoot several people, and three arrows can be sent hundreds of steps."

"The artillery cart is in the array, and the flint cannon is also two hundred steps."

This gunpowder is still quite useful.

I just don't know if it's powerful.

Yun Ya'er didn't bother to watch her tinkering on the ground, so she simply went to the small stove to boil water.

That dirty hand, if he soiled his quilt, he would beat her.

It's just that.

He had just started the stove and was about to fetch water when he heard a purple fire burning in the courtyard.

And then......

"Bang-"

The sound exploded, and the boy was driven out at once.

In the courtyard, the ground was charred black, the bamboo chairs were burning, the sparks were everywhere, and the air was full of smoke.

"I'm scared to death"

Su Liuyu slipped away quickly, and was also frightened by this movement in a cold sweat.

"It's so dangerous, I almost blew me up."

The thin little body like black charcoal stood in the corner of the yard and sighed.

Yun Ya'er saw her at this time.

A corner of the dragon's robe was burned, and his body was full of dirty black ash.

And that's not all.

One face is also dark.

Because it's late at night.

I could only see a pair of eyes, staring in horror.

His face darkened.

"Su Liuyu!"

The young man dragged her over, scolded and yelled:

"You're looking for death, aren't you?"

It's fierce!

Su Liuyu plucked out his ears and grabbed his sleeve with dirty paws.

"If you make a mistake, I'll just try a few more times." She reassured, "I won't fail next time." ”

And next time!

Yun Ya'er looked at the messy yard, and the green muscles jumped suddenly.

Xiao Baihua summed up in her heart that the power in her mouth is to find death, so this thing is dangerous!

Can't touch it!

Therefore, the next day, the whole palace knew that his emperor was ready to die.

It's worth it!

Wenchen admonished, the military generals asked for their lives, and the minions cried.

Countless pairs of eyes looked at Su Liuyu firmly.

"You're trying to scare the minions to death."

"If the emperor is injured a little bit, Weichen will not live."

These people desperately let her stay away from any flint.

No matter how important the ordnance is, it is not more important than your own emperor!

Even Shen Huaizhou was shocked.

He used to indulge his apprentices.

But the only bottom line is Su Liuyu's safety.

Don't say how powerful this thing is, it just won't work anyway.

It's a mess.

Su Liuyu felt bitter in her heart.

"You're making the wrong formula."

A deep, cold voice sounded.

"Aristolochia is to be used instead of soaphorn to go to the fire, and saltpeter is to be added to the sulfur, and sulfur is to be added to the saltpeter."

Yun Xuzi shook the banana fan, saw her squatting by the stove pitifully, and snorted.

"In the future, don't destroy the medicine of the poor road, or ......"

Su Liuyu's eyes lit up.

"Brother, you are too brother!"

She immediately stood up.

"Thank you, brother."

"You!"

What is it called.
