Huang Yu took the brass box handed over by Po, and looked at the 'Nine Palace Lock' in front of the brass box, which was different from the ordinary wooden box, and confirmed his guess even more.

The original latch position directly in front of the brass box has been replaced by nine small lattices. Each grid is carved with a hexagram corresponding to the direction of the eight trigrams of the day after tomorrow: Zhen, Xun, Li, Kun, Dui, Qian, Kan, Gen, and the middle palace is centered to determine the eight directions. Seeing that the gossip was arranged in the order of the nine palaces, Huang Yu remembered what the master had said to him: "When the 'Nine Palace Lock' was designed, the reference was the 'Luban Lock', but the 'Luban Lock' had no anti-theft measures, so the ancestor of the sect referred to the Luban Lock and the Bagua and the Nine Palaces to design the 'Nine Palace Lock'. It's just a lock."

"Although there are no active anti-theft measures in the Nine Palace Lock, as long as the things that are locked up with the Nine Palace Lock, they are all 'sealed' or 'spells' that need special preservation, so it is easy to deal with. If the secret box is stored in a secret scroll that must not be transmitted to the outside world, as long as an outsider opens it in the wrong way, the mechanism left in the mezzanine of the secret box will be triggered, and the white phosphorus powder and refined nitrate powder in the mezzanine will start to burn violently when triggered by the mechanism, and the secret method scroll will be burned clean in an instant."

"If it's a sealed 'spell', it's even simpler, as long as someone dares to break the Nine Palace Lock, the mechanism in the box will unlock the sealing runes by itself. The person who opened the box, even if he didn't die, the strange 'spells' inside could make the person who opened the box drink a pot."

Huang Yu's hands trembled uncontrollably, on the one hand, he was too excited in his heart, and the master finally knew about his apprentice; On the other hand, I was still a little frightened by this thing, after all, there was a 'spell weapon' in it, and the shadow of the pit last time came to my mind again, so that the small brass secret box in my hand almost didn't hold it.

"Hey, my master's search, all I used to give me were some spells with great side effects, and I couldn't use them. I accidentally 'used' it once last time, and I almost didn't get up for half a month. If it weren't for me being framed this time and falling into someone else's game, would my master be able to give me this treasure? Huang Yu thought helplessly about the old man who was searching, and complained to Bao.

"Hahaha", "You are really a master and apprentice, when Yichen's predecessor asked me to get this thing half a month ago, I also had a painful face, and I also waited for a long time to get it", Ah Bao remembered that he suddenly received a call from Yichen's senior half a month ago to let him go down the mountain to get the brass secret box, and he couldn't help but laugh when he remembered the painful expression on the face of the old man, haha.

Looking at Ah Bao, who was holding his stomach and laughing, Huang Yu had no smile on his face. Looking at that stunning pretty face, and thinking about Ah Bao's character, Huang Yu always felt that his teeth hurt.

Hurriedly interrupted Ah Bao's demonic laughter, and asked seriously: "This time it is also three hexagrams, six passwords?" ”。

"Hah...... ah! Yes, Yichen's predecessor told me that it is still the simplest three hexagrams, but I can't tell you the answer, you have to observe it yourself, you have three chances to confirm the answer with me, and after three failures, I will personally help you open the Jiugong lock, but Yichen's predecessor said: 'That stinky boy can't even open the simplest Jiugong lock, so let's go back to my hometown and plant sweet potatoes!'" Don't be my apprentice! Phew, shame! Ah Bao held back the smile just now, and said to Huang Yu in a serious way.

Hearing Ah Bao's relay, Huang Yu threw away the idea that the old man who was still thinking sweetly about the master just now would still hurt his apprentice. Huang Yu said fiercely: "That old stubborn! Look down on me every day! Let you see what the master is capable of! ”。

Huang Yu forcibly regained his composure and carefully weighed the copper box in his hand. Huang Yu gently shook the copper box in his hand, and the outside of the copper box could feel the shaking sensation of yin, saying that there was liquid inside the copper box. Since there is liquid, it is almost certain that the treasure: a thousand noodles.

According to my master, it was his old man and others who were on their way to flee overseas. Encounter a wild boar on an unknown island. The boar bit when it saw a man, and when the man was killed by the beast, he opened his mouth and devoured the carcass on the ground.

At first, because it was at night, everyone didn't see clearly what was attacking everyone, but later a few good hands on the rivers and lakes relied on the sharpness of the weapons in their hands and prepared to step forward to kill that thing. But two of them were killed by the wild boar by relying on its flexible body, and the person became the belly of the wild boar.

At this point, all the living people paid attention to it, and a few masters didn't care, thinking that a few of their subordinates could kill the beast, but they didn't expect that two of their subordinates died unexpectedly, and they had to give two heads.

When everyone had put out their weapons and put their torches on fire, the brute felt that something was wrong. Originally, by the faint light of the torch, Yichen thought that what he saw was a wild boar. But as the boar-like creature raised its head and cried out, "Wow, wow, wow," Yichen saw a human face, the face of one of the two who had just died on the ground, and heard the cry of a baby on an uninhabited island.

Yichen searched in his mind, and then found out that this thing is not the joint hole in the Book of Mountains and Seas? The mountains and seas pass through the east mountain and have clouds: "Two hundred miles to the northeast is called the Yan Mountain." Much gold jade. There is a beast, its shape is like a human face, a yellow body and a red tail, and its name is called Hejiao. It sounds like a baby. It is a beast, a cannibal and an insect-eating snake. When you see it, there is a lot of water in the world".

Yichen doesn't look at this thing very much like the description of the Mountains and Seas in the Classic of Mountains and Seas. Although this 'wild boar' also has a human face, that face is too blurry, and at first glance it looks quite like the face of the previous person, but on closer inspection, it doesn't look like it very much. It still looks like a wild boar, and its fur is black and gray, and it is not clear what the tail looks like because of the lack of light.

After Yichen said the situation of Heyao, everyone rushed up and slashed at Heyao together, and Heyao saw that there were all people around him and was not afraid, and after screaming, he rushed towards everyone. It may be that the last one died in the chaos of the knife, and the combination also successfully killed the two before he died.

Just when everyone cut off Heyao's head, Yichen came forward to leave the pig's head, and everyone dug a pit to bury the person who was bitten to death by Hejiao and the headless corpse of Hejiao on the spot, and also asked Yichen, a Taoist priest, to do a simple supernatural ritual.

When everyone was resting, Yichen used the knife he carried with him to cut off the skin of Heyao, and sure enough, the constantly changing, thin face as a cicada's wings verified Yichen's conjecture, and it was a pity: "It's a pity, it's such a terrible talent!" ”。

Yichen only then discovered that this Heyao had an innate talent and supernatural power: Thousand Faces, but it was a pity that this Heyao with impure blood had no chance to cultivate this talent and supernatural power to Dacheng. Looking at the constantly changing contours of his facial features, Yichen counted them, but there were only five different faces, and Yichen thought: It seems that I have to find an opportunity to 'feed' this face.

Huang Yu thought to himself: "This story tells me an answer, if this answer is correct, then I can probably guess what the first two hexagrams are, so what is the last hexagram?" ”

"I still haven't thought of the last hexagram, can I mention it...... Hmm", Huang Yu thought for a while, and didn't think about what the last hexagram password was, and then he suddenly realized when he looked in the direction of Bao.

Huang Yu slapped his head suddenly, a little angry, and a little funny: "It's still an old man, my master is really ...... to test his apprentice!"

"Tianshui, Tiantian, thunder", Huang Yu said confidently.

"Yes, yes, Senior Yichen said that you must be able to answer correctly!" , Po said happily.

Untying the code of the Nine Palace Lock, Huang Yu took out the face that was as thin as a cicada's wings soaked in the potion from the copper box. The skin of the face is cold to the touch, and the texture is not like a leather product, but like a papai of yarn used by ancient people, light and soft.

"Quick, quick, quick, take it and try it, I haven't seen such a magical spell work yet!" , Ah Bao urged Huang Yu with a smile.
