Gai Nie put the box on the low table, Gu Nan looked at the box curiously, the box was about one meter long and no more than ten centimeters wide, and the overall look was a little slender, but he didn't know what it was.

Guiguzi sighed and looked at Gu Nan helplessly.

"Open it up and see for yourself."

Gu Nan looked at the box puzzled, stretched out his hand, and put it on the lid.

The lid of the box opened, but inside was a pitch-black ancient sword.

The unremarkable scabbard has no patterns on it, and the style is also very strange, with no sword lattice (handguards), and it is impossible to distinguish between the sword body and the hilt. It looks like a burnt iron rod.

The only thing that made it clear that it was a sword was a slit between its integrated scabbard and hilt.

Gu Nan strangely picked up this unsightly sword and opened the scabbard.

Different from the pitch black of the scabbard, the blade was bright and bright, illuminating Gu Nan's eyes.

There are also no patterns on the sword, like a clean and thorough Hongguang.

Slowly pulled out the sword, the blade was very thin, but it inexplicably gave Gu Nan a very strong feeling, and when the long sword was pulled out, it didn't have the appearance of burning iron rods.

Sharp.

The sword was withdrawn from the scabbard, the sword light disappeared again, and Gu Nan put the sword back.

Nodding: "The sword is good." ”

"That's good." Guiguzi said: "This sword was asked for by the old man and an old man. It was useless to put it in his hands, so it was given to the old man. ”

"The disqualified sword, I don't know the age, I don't know the material. The old man tried, and it was unusually strong and sharp. ”

Saying that, he looked at Gu Nan: "Your sword path is a way to kill with one blow, fast, ruthless, accurate, and fatal, almost defenseless." ”

seemed to remember the last time he fought with Gu Nan, and shook his head with a smile: "You can even do this kind of thing of throwing a sword and attacking, only attacking but not defending, come to think of it, this unqualified sword is very suitable for you." ”

"You don't have a sword blade to take advantage of, so the old man cut his love and gave it to you."

···

Gu Nan was silent for a while, looking at the sword on the table.

There was some emotion in his eyes, there was an old man who thought about her everywhere, but how could he not be moved?

smiled and picked up the burning iron rod: "Then I'm welcome." ”

At the end, he added: "Thank you." ”

Guigu smiled and touched his beard: "I want to hear thank you from you, it's really not easy." ”

"Give this sword a name, and in the future, as you are born and die, you should have a name."

Gu Nan looked at the sword in his hand and was slightly distracted.

After a long time, he said firmly.

"Just call it, burn the iron rod!" (At the end of the Warring States period, there were already iron tools, but most of them were agricultural tools.) ）

"Smack." Wei Zhuang and Gai Nie, who were kneeling on the side, shook their shoulders.

However, the snap was not made by them, but Guiguzi slapped it on the table with one hand.

"No way!"

"Why..." Gu Nan was a little depressed, Brother Hei's name at that time couldn't follow her wishes, and this sword didn't work out this time. He gestured unrelentingly: "It's obviously very vivid." ”

Why?

Guiguzi trembled his eyebrows: "No, no, no!" ”

"Hmmm······" Since Guiguzi insisted, Gu Nan had to think about it again.

Sitting cross-legged in his seat, bracing his knees, frowning.

"If not, it's called no grid, anyway, there is no sword grid."

Unqualified···

Although it is still a little unsatisfactory, it is already much better than the name of burning iron rods, anyway, it is already given to her, let her go.

He waved his hand: "That's it." ”

But I didn't know that in the future, the attack would not be defended, and the name of the black sword would be decided.

Well, it's really better than attacking and not defending, and the black burning iron rod······

Just when Gu Nan wanted to say something more, Guiguzi suddenly took the sword with the scabbard in his hand and pointed straight at Gu Nan.

This sword is not fast, but it is magnificent, just like the vast world is bound to this narrow scabbard, and with the sword path, it collapses.

A sword, as if tearing something apart, with a violent roar in the dark.

For a moment, Gu Nan only felt that the cold air on her body was shrouded, and only the sword was left in the heaven and earth, and she had no room to get out of the house.

Xiao Zhuang and Gai Nie on the side took a step back, they couldn't withstand the power of this sword at all, even if it was Yu Wei. The strong internal strength and sword intent are not something they can spy on.

Shocked in their hearts, they had almost never seen their teacher actually make a move, but this time this sword was just watching from the sidelines, which was enough to make them powerless to resist.

"Buzz!"

There was a slight buzzing sound, followed by a cold light that lit up Wei Zhuang and Gai Nie's eyes.

A sword that was quick to see clearly, leaving only the arc of light in its eyes.

Gu Nan couldn't bear this power, although she knew that Guigu wouldn't really attack her, but subconsciously, she still made a move.

And as soon as you make a shot, it's all your strength.

The extremely fast stabbing sword, Wei Zhuang and Gai Nie stood aside in a daze, and in an instant, this sword had already stabbed out twelve swords, which was the unqualified sword.

It's a pity that these twelve swords were all crushed by the mighty sword momentum of the Ghost Valley, and they were taken back before they could make contact.

In the end, the thirteenth sword, the scabbard of Guigu had been sent to the front, Gu Nan flew back, but the sword in his hand did not retreat but advanced.

The inner breath was surging, but Gu Nan used all his strength, and this thirteenth sword became a match in the vast world of the Ghost Valley, as if falling into the light.

Thirteen swords, but one breath. This sword is already unimaginably fast, Gai Nie Weizhuang and the others only feel cold all over their bodies, and they fall under that kind of sword, I am afraid that they don't even know that they are dead.

"Dang!"

The two swords finally touched.

The tip of the sword rests against the head of the scabbard.

It was not the shock that was expected.

The two of them retracted at the same time, only to make a soft noise.

It's like just holding a sword and gesturing.

Guiguzi put away his sword with a smile, and nodded as if he was very satisfied with Gu Nan's performance. It seems that it is because of the previous sulking, and the heart is refreshed.

"Whew." Gu Nan breathed a sigh of relief and wiped the sweat on her forehead, but she barely blocked this sword.

looked at Guiguzi complainingly: "Ghost old man, don't you do it without saying a word, you want to dismantle me?" ”

As he spoke, he sat down again, remembering the sword just now, and lost his mind slightly.

Thinking of something, he smiled and said, "Your sword intent, breakthrough?" ”

"Not yet." Guiguzi looked a little complacent, after all, he can now be regarded as standing at the peak of the sword path of this era: "The realm without a sword is very profound, the old man has been enlightened for more than a year, but he has only realized this sword, and he is still half a step away from really entering that door." ”

said with regret: "But I don't know if this half step, the old man can reach the ······ in his life."

"It's impossible to find things." Gu Nan was happy for Guiguzi and poured him another cup of tea: "I don't want to force it in my life." ”

"Don't force it." Guiguzi glanced at Gu Nan: "If you don't force it, how can you compete with heaven and earth for the avenue you want?" I fight for the sword, you fight for the Lang Lang Qiankun, and the people in the world are all demanding. What do you do in your life? ”

"You're just lazy, and you shouldn't be like this if you weren't like that."

"That can't be helped." Gu Nan raised his eyebrows: "I was born like this, I can't change it." ”

Reply to the book review. Some people say that in the Battle of Changping, the Zhao army was 600,000, and the Qin army was 300,000. I've checked the information about this, and the most said is that the strength of the Zhao army is 450,000 (from the biography of Bai Qi Wang Jian in the historical records, and Lian Po Lin is like a biography.) The strength of the Qin army was only 100,000 at first, and it was increased to 400,000 during the confrontation period, and it is also said that there were 600,000 troops, which was comparable. Judging from the contradictions recorded in the historical books and the population and economy of the Warring States period. This figure must be a bit exaggerated, but there should be no doubt that the Qin army finally invested more troops. There are many records of this history, the number of people who participated in the battle, the number of regular soldiers, and the number of people who really killed in the pit, and the number of casualties are all problems. There are also different opinions. History can't be examined, and my novels can't be written as history books, I just wrote a number that I learned that there are relatively many people, so I don't need to take it too seriously.
