The Imperial Sword Master continued, "After the Yan clan was wiped out, it looks like it disappeared from the Northern Shejiao and disappeared from the land of Lechuan, but I always feel that things are not so simple. ”

"When any family encounters a catastrophe, the first thing that comes to mind is how to protect their descendants, even if only one seedling is left, his family will not really be extinct, and there will be hope for revival in the future. ”

"I believe that there must be descendants of the Yan clan left in this world, if this is the case, they must have become a big climate through hundreds of years of Taoguang. ”

Xu Dong asked, "What do they want to do?"

The Imperial Sword Master said, "It's impossible to say what you want to do, but there is no doubt that they have inherited the serpentine trick, and they may become more and more exquisite." ”

"The serpentine trick can be said to be the best in the fighting techniques that appeared at that time, known as the first in the world, and its re-emergence is estimated to be enough to make the rivers and lakes turbulent. ”

Xu Dong has been thinking, "Is there a technique that can crack the snake trick?"

The Imperial Sword Master said, "Your reminder reminded me of one thing, this matter was not made public at that time, it was only rumored in a small area in private, and later with the destruction of the Yan family, this matter became an unsolved case. ”

"What?"

"After every peerless martial art appears, there are inevitably people who study the way to crack it, and the three families who are in a panic are even more concerned about this matter, and it is said that there is a genius who has made this matter nine times out of ten. ”

"Is that really the case?"

"I think this is true, it is said that after the Yan clan was destroyed, the founding monarch of the Ratuo Kingdom went to Lethe River, and the Northern Shejiao sect dedicated this technique to the monarch in order to preserve the sect. ”

Xu Dong was surprised, "Is that so?"

"There is one thing that is difficult to distinguish between the true and the fake, that is, this technique is embedded in two pieces of black iron, and the Northern Shejiao is perfunctory to the monarch of Ratuo, but he only gave one of them, and the other is missing. ”

Xu Dongdao, "According to what you said, this technique is actually broken into two, and it is difficult to put it together anymore?"

"Yes," said the Imperial Swordsman, "that's it. ”

Like a drill bit developing Xu Dong's mind, he thought about it for a long time, and finally carved out some Taoism.

"If I'm not mistaken, they must be looking for this piece of black iron, and they must have found out the exact information, this piece of black iron is in the hussar camp. ”

He continued, "Didn't the founding monarch have ten treasures left in the Imperial Swordsman Camp before he set out on the expedition? ”

"The reason why they rummaged through several supervisors in the general camp was not because they thought they could find the black iron sheet, but because they wanted to find some text basis indirectly, and then find the black iron sheet according to the map. ”

"Yes, they think that if they find the black iron piece, or destroy the black iron piece, they will have no way to crack the snake trick they have mastered, and they can have their own skills." ”

The two geniuses, one old and one young, combined their minds to come up with a more reasonable explanation for what has happened recently.

Xu Dong said, "Then I have one more thing to do now, which is to find the black iron piece in the hussar camp first, and then go to Lechuan to try to find another black iron piece, and then seek to crack the snake trick technique." ”

"Have a brain, your idea can completely overlap with what I think, so let's do it!"

Xu Dong said goodbye to Yaqian and the Imperial Sword Master, came out of the Lotus Cave, and looked up at the barren meadow, and saw Chaochao chasing and playing with a group of wild sheep.

He was a little depressed in his heart, thinking to himself, I don't know when he will be able to find a godhead for Chaochao, let it return to the Lotus Cave, and end this day of natural cultivation.

Xu Dong returned to the hussar camp to meet Yan Laohu, and took the initiative to take over the case related to the serpentine trickster.

Since the ambush at Xing Bing's house, the man and woman have never appeared again, and the turmoil seems to have subsided, but Yan Laohu and Xu Dong analyzed that this was just a temporary calm.

Yan Laohu summoned the supervisors of the battalions and asked everyone to put the documents and treasures scattered in the alliance in the treasury of the general camp for unified safekeeping, and he arranged more than 20 guards to take care of them.

Xu Dong stayed in the treasury of the main camp all day, wandering among a large pile of documents and ten treasures, and he buried his head in the middle of these things for three days and nights, but he did not find any information about the black iron piece.

He was a little tired that night, and fell asleep in the pile of old papers, and in his sleep he saw the pure gold armor scattered like beads of broken thread, and pieces of gold shining one inch in size.

He stared at the scattered pieces of gold in amazement, and suddenly, he noticed a piece of gold that was of a different color, and quickly captured the information in his mind.

It is said that the color is different, but the color is darker, with a red color, like a piece of fine charcoal that has not been burned out.

Is this a piece of black iron? This piece of black iron is hidden in the golden armor.

But this is clearly red, how can it be called a black iron piece?

Xu Dong woke up from his sleep, rubbed his worried eyes and walked into the tent, took out the pure gold armor from a large iron cabinet, and examined it carefully.

Of course, this armor is different from ordinary battle armor, it is made of tens of thousands of gold pieces that are not much bigger than a finger, and they are made of slender gold threads like silk, which looks dazzling and makes people's eyes burn.

Although Xu Dong searched very carefully, he looked at the gold armor many times from beginning to end, but he still couldn't find the gold piece with a different color.

Attentively, he found a stick and struck the gold pieces one by one to see if any of them made a strange sound.

All his attention was focused on his ears, and at this time, it was believed that even a speck of dust would be captured by his ears.

The hard work paid off, and he finally found the sound of a piece of gold, which was a little different from the sound of other gold pieces, and its voice was a little hoarse.

He pinched the piece of gold in his hand and looked at it, and it was impossible to tell the difference in color, because it was a sandwich, and when he peeled back the gold sandwich, there was a piece of dark iron.

Xu Dong knew that some exercises were engraved in jade and dark iron, among which jade was common, and only a very special use of dark iron was used, because the smelting process of dark iron was particularly complicated.

However, the capacity of dark iron is larger than that of jade, and it remains unchanged for a long time, so it can be said that the exercises carved with dark iron will not die as long as the celestial body does not explode.

It can be seen that the original creator of this exercise should have spent all his efforts, and it can really be said that he has put in great pain, and his will is comparable to a golden stone.

Xu Dong couldn't wait to inject divine thoughts into the Xuantie piece, and after pouring it for about half an hour, the seal on the surface of the Xuantie melted little by little, and the lines of handwriting inside were faintly revealed.
