There was a mess all around, obviously passing through the war-torn post station, and the wounded were lying on the ground, and her eyebrows couldn't help but show a solemn look.

If this scene were to be changed by a century, what would be the difference between her previous life in the battlefield?

Seeing that a painful wounded soldier was about to pull out a broken arrow from her body, she couldn't help but shout, "Don't move." ”

The soldier never expected anyone to notice his movements, and froze in place.

And Feng Jiutian had already walked over quickly.

Looking at Feng Jiutian, who had already entered the role of a doctor, Dong Yi touched his chin, and then said, "His Royal Highness King Sheng, Miss Feng is a rare good doctor." ”

Nangong Ling's throat seemed to be blocked by something, and she didn't say a word, and in the end, she could only give Dark Qi a look.

Dark Qi immediately followed Feng Jiu, protected her left and right, and gave her a hand by the way.

But he still had a thorn in his heart.

Although when he was in Lingshui County, Feng Jiutian had saved the people of Dayan.

But this time, it was Dayan who was at war with the Western Regions and the barbarians, and Feng Jiu's identity as the young master of the Western Regions was there......

Nangong Ling looked at the busy people and knew that she was suspicious.

He just selfishly hoped that Feng Jiutian would not get involved in this war again.

His eyes were dim, but when Dong Yi looked over, he had already restrained his excess emotions.

He said: "General Dong, you have more experience than me in the matter of the barbarian cavalry, let's go in and talk." ”

Dong Yi immediately smiled, he was waiting for now.

And this one, Feng Jiutian had already dug out the arrows on the soldier's body and bandaged the wound.

It's just that this has just been dealt with, and there are one after another waiting for her to be appeased.

The air was filled with the smell of lifeless blood, as well as a ...... Quirky vibes?

Feng Jiutian twisted her eyebrows fiercely, her nose twitched slightly, sniffing the strange smell in the air.

Dark Seven was stunned when he turned around and saw her movements.

He was full of suspicion, but when he saw Feng Jiutian's serious appearance, he closed his mouth again.

In the end, it seemed that the source of the smell had been found, and Feng Jiutian stared at the bloody arrow that had just been pulled out.

I saw that the scissors were very sharp, but the sharpened head was smeared with a layer of yellow and black mixed things.

Feng Jiutian picked it up and sniffed it as if confirmed, and his eyes instantly became a little more solemn.

Dark Seven was shocked by her movements, and hurriedly asked, "What is the princess doing?" ”

"Do you smell a strange smell?" Feng Jiu tilted his brows, still in a serious tone.

Dark Seven knew what she had discovered when she saw it.

He took the scissors in Feng Jiutian's hand, carefully identified them, and then said: "This arrow has been burned by fire, usually because it has been smeared with fire oil, but ...... It's not just the smell of fire oil. ”

He also noticed a strong strange smell in the air, but it was very unfamiliar, and he couldn't explain why.

However, Feng Jiutian was all too familiar.

This is a mixture of saltpeter and sulfur, and when these two substances are combined, they are gunpowder!

She examined the wounded soldier and saw that his wounds were not all arrow wounds, but more like those that had been affected by the explosion.

Feng Jiutian grabbed a civilian man whose injuries were not so serious, and asked, "How did you get this injury?" ”

The man was in a trance.

But when he heard Feng Jiutian's question, the person immediately became excited.

"I don't know, it's just that a burning arrow with a bag of stones hanging from the yard suddenly came in, and my big treasure is ignorant, so he leaned over to pick up ......"

"I hate it! Why didn't I stop it! Just watched as the arrow burst into flames and then exploded! ”

"My son, my son will ...... at once"

When it came to the sorrow, the man burst into tears and couldn't go on.

Feng Jiu's heart couldn't help but feel sad and sympathetic, but he didn't know where to open his mouth to comfort.

But listening to the man's description, she already got the answer she wanted in her heart.

No wonder most of the battlefields on this battlefield are left with only arrows.

These saltpeters and brimstone are probably just small packets hanging from the arrows, and the fire burns up, and the second explosion will blow people up.

But such a weapon has actually appeared?

She had learned about Dayan's weapons in the memory of the original owner, and there was no gunpowder.

Since the Western Regions and the barbarians have been suppressed by Great Yan, how could they be advanced enough to have gunpowder weapons?

Dark Seven was listening, and his expression was also stunned, "What kind of weapon is this, and it will suddenly explode?" ”

Feng Jiutian glanced sideways slightly, she used to be a doctor on the battlefield, she received military training, and she naturally thought more.

Weapons represent the absolute right to speak in war.

The Western Regions and the Barbarians suddenly joined forces to raid Dayan, was it because they had mastered this explosive weapon?

"Dark Seven, you'd better keep an eye on this weapon." Feng Jiutian opened his mouth cautiously.

Dark Seven is a secret guard, who has been around Nangong Ling for a long time, and naturally knows the influence of this extremely damaging weapon.

Feng Jiutian pondered while bandaging the other patients.

Suddenly, a flash of inspiration occurred to me that the person who mastered saltpeter in ancient times was a kind of person called an alchemist.

This group of people is also a healer in nature, but they are engaged in the mysterious and secret practice of the gods.

According to investigations, these alchemists were the first to use saltpeter in human history, and their notes even contain records of gunpowder recipes.

And in the memory of the original owner, there are also alchemists in the Western Regions.

Everything seems to be on the right track......

Feng Jiu tilted his head to Dark Seven and said, "Dark Seven, these things ......"

However, as soon as Feng Jiu said this, Dark Qi suddenly stood behind her vigilantly.

"Princess, be careful!"

As soon as Feng Jiu turned around, he saw that outside the post station, on the small hillside a few hundred meters away, several figures rushed over in embarrassment.

With just one glance, Feng Jiutian was almost certain that they were soldiers patrolling the border pass!

They looked very embarrassed, and one of the soldiers still had undried blood on his face, his eyes were frightened, and he was still shouting something.

It was too far away, and it was in the dialect of Huacheng, and Feng Jiutian didn't understand it for a while.

But when she was puzzled, she found that the dark seven body around her had tensed, and the people and soldiers of Huacheng around her were also nervous.

"Enemy attack! It's an enemy attack! Someone shouted in horror.

Immediately after, dense black dots on the hillside suddenly appeared, and they turned out to be black arrows!

"Pss

The arrows pierced the patrolling soldiers who were running back to report the news.

Blood sprayed out as if they didn't want money, and one by one the fleeing figures suddenly fell to the ground.

Feng Jiutian's eyes widened.

Behind the arrows, she saw several figures dressed strangely on the hillside, and in their hands were the bows and arrows that shot them.

There was chaos around Feng Jiutian.
