"Xiyan, what's the name of this iron box... You haven't said it yet." Xu Ke asked with a smile as he looked at Xiyan who jumped in the sun.

"Ah! I forgot this, big brother, hehe! Sorry! Is this iron box a special name called "Sixiang Cangxu"... It is square, with six inches on each side, and there is another universe in the box. Don't look at it outside and look like a small box inside, but it's so big!..." After hearing Xu Ke's question, Xiyan touched his chin embarrassedly and replied.

Xu Ke kept holding this iron box in his hand. Along the way, he felt that the weight of the box was sometimes heavy and sometimes light. He had always been unclear before, but now he realized it after listening to Xiyan's explanation. So he asked again:

"Why did your master say it was a three-star box? Then... I asked me to find a way to open it myself. Is there something rare in this box? I saw that there was not even a crack outside the box, so how should I open it?"

Xiyan took the "Sixiang Cangxu" from Xu Ke's hand, and pouted and said while playing around:

"The old man is so partial! I have been with him for more than ten years, but I have never had a decent treasure. Today, he just met you and gave you this treasure of the temple!... Humph! You stinky old man, terrible old man, bad old man! I won't make you delicious tonight!"

Xu Ke hurriedly smiled and said, "Little brother, if you like it, this... is called "Sixiang Cangxu", I will forward it to you! Just wait a moment, don't delay your master's supper..."

Xiyan smiled and said, "Big brother, I'm talking about it! This 'Sixiang Cangxu' is a gift given to the old man, and I dare not ask for it! Besides, there are good things hidden in this box. The eldest brother doesn't accept it, but I will regret it... Don't worry, Xiyan will do his best to the old man's supper. I will make him a bowl of 'Senna leaf big soup' later... Hehehe!"

Xu Ke had no choice but to smile. He had many questions in his heart, but he didn't say anything at this time, because the Taoist boy had not replied to a few questions he had asked before...

Seeing that Xu Ke stopped talking and did not ask him what "Senna Leaf Dapu Decoction" was, Xi Yan suddenly felt bored, so he returned the "Sixiang Cangxu" to Xu Ke and said:

"Big brother, do you know that there is a place called Tianbao Pavilion in Chang'an City?"

Xu Ke thought to himself that this little Taoist boy was really imaginative, why did he ask about Tianbao Pavilion again? He had to reply:

"I've been to Tianbao Pavilion a few times. Why... Is my little brother Xiyan very familiar with the people there?"

Xi Yan said: "This Tianbao Pavilion is one of the three pavilions in the world. How could I know the people there? However, I heard from the master that there is a book called "Tianbao Directory". The book records all the powerful weapons, Taoist weapons, and magic weapons in the world. The masters of all dynasties have been continuously supplemented and collected. Therefore, the "Tianbao Directory" can be regarded as the most complete book collected from ancient times to the present. In the "Tianbao Directory", all the powerful weapons in the world are divided into five types, namely "One Star Grass Tool", "Two Star Mirror Artifact", "Four Star Spiritual Artifact", and "Five Star Divine Artifact"... Unfortunately, according to the book, most of the powerful weapons are just one star and two stars. There are only a few that can be listed above the "Three Star Magic Artifact"..."

"The 'Sixiang Cangxu' of the Master is a 'Three-Star Magical Artifact'! This gift... is too expensive..." Xu Ke said.

Xi Yan said, "It's a sloppy! Big brother, didn't you give the old man a piece of East China Sea spirit stone? That spirit stone is an authentic three-star magic weapon! It's a bad idea to come but not go. The old man's business is not a loss, nor is it a loss..."

Xu Ke thought to himself: "No wonder, I heard that Yulu Weng and Suzhou Land Lord were talking about 'two-star' and 'three-star'. It turned out that they were all determined by the book of the Murong family. It seems that this "Tianbao Directory" is really extraordinary..."

Xiyan saw Xu Ke thinking to himself, then pointed to the sword on Xu Ke's back and asked with a smile:

"Big brother, do you know how many stars are the Kunwu sword on you in the "Tianbao Directory"?"

"I guess it's always above the two-star instrument..." Xu Ke replied casually.

"Hahaha! I'm so laughing! That Kunwu sword is famous, but it's actually only given the title of "one-star grass weapon"!" Xi Yan smiled and said with a smile.

"This..." Xu Ke couldn't help but secretly wonder: "My name Kunwu sword, blowing gold and cutting iron, is so sharp that it is Wuruan, how can it become a 'one-star grass weapon'?! According to this speculation, I really don't know what is so powerful about the 'Four Symbol Cangxu', which is ranked among the 'Three-Star Magical Artifact'..."

Xiyan seemed to see Xu Ke’s thoughts and continued:

"Big brother, don't think that your sword is sharp, but you're trying to hit the iron box in your hand?"

"When my Kunwu sword comes out, will the box be split into pieces?" Xu Ke asked back.

"Hahaha! Big brother, just draw your sword and try it. You will know..." Xiyan smiled.

Xu Ke didn't believe it in his heart. He thought to himself that I only drew the sword a few times, and I don't know how many people were cut into two pieces. Can't you cut a mere iron box? He was determined not to draw the sword, but in the end he was a young man. He couldn't help but inspire Xi Yan, so he put the "Sixiang Cangxu" on the ground and pulled out the Kunwu sword from his back. He didn't dare to be lucky, but just held the sword and slashed it gently at the corner of the iron box...

Just heard a "ding" sound, swords and iron intersected, and sparks emerged. Xu Keman thought that the iron box must have been cut off a corner. After a closer look, he saw that the iron box was placed steadily on the ground. Not to mention cutting off a corner, there was no scratch at all.

Xu Ke looked at his Kunwu sword again, but he couldn't help but take a breath. He saw that a cut had broken out of the edge of the sword blade. Although the cut was not big, it seemed shocking at this time...

"Hahahaha! I'm so laughing to death! Big brother, now I know that Xiyan hasn't lie to you! Fortunately, you didn't have the luck to be honest just now. If your strength is more important, your sword given by the emperor will be broken... Hahaha!" Xiyan laughed loudly, and while laughing, he also stomped his feet and clapped his hands, as if he had picked up a treasure, and was inexplicably excited.

Xu Ke lamented, and had to go back to the sword and put it into the sheath. Although the Kunwu sword had only been with him for more than a month, he had helped him to escape danger several times. Xu Ke felt grateful for it. Now, he saw that his "love sword" had been broken for no reason, and he felt inexplicably heartbroken, but at this moment, there was no other way except to regret that he had just started to draw the sword...

"Well!...Big brother! Xiyan knows a master who uses swords. He has several famous swords at home. Next time, Xiyan will ask him for one and give it to his elder brother! This Kunwu sword... Actually, it looks fancy and jewel-like. It's useless when it comes to the enemy..."

Xu Ke picked up the "Sixiang Cangxu" on the ground, took it and left. He was still in the "pain of breaking the sword" just now, and he was just hoping to think of some way to repair the gap in the sword blade.

Xiyan chased after him and said with a grievance:

"Big brother, I'm sorry! I shouldn't have joked with you just now, don't be angry... Well, I'd better tell you how to open the "Sixiang Cangxu" method. The master didn't let me say it, but I'll say it now. Even if I make up for the merits, would it be fine?"

At this time, the two had already walked to the gate of Xuandu Temple. Xu Ke couldn't help but stop. He wanted to say, "Since the respect for the teacher doesn't let you talk, it's better not to say it." But at this moment, he saw the expression on Xiyan's face, which was both aggrieved and pitiful, and he couldn't bear it. He thought to me how could I be angry with a child? So he turned around and said to Xiyan with a smile:

"Big brother is not angry. He just has a sword. If it is broken, it will be broken... Xiao Xiyan, then you can tell me how to open the iron box..."

Seeing Xu Ke smiled, Xi Yan smiled and said, "Well... these four symbols Cangxu, the four symbols are the four poles of heaven and earth. The east is the blue dragon, the west is the white tiger, the west is the Shaoyin, the autumn, the north is the Xuanwu, the old yin, the winter, and the south is the Vermillion Bird, the old yang, the summer. Cang is the big meaning, and as for this emptiness, it means infinite. If the elder brother wants to open the box, he needs to find a secluded place and use his true energy to slowly rub the four sides of the iron box. You will see four holy beasts appearing on the four sides of the box, and the two sides will reveal the words "cang" and "xu".

After a pause, Xiyan said again:

"Big brother must follow the order of the sun, moon and stars, from east to south, from south to north, then from north to west, and finally from west to east... You must first rotate the Qinglong side in the order of southeast, then rotate the Zhuque side in the order of north and south, then rotate the Xuanwu turtle and snake side in the order of north and west, and finally rotate the White Tiger side in the order of west and east to the bottom... Then, the sluice in the "Four Symbol Cangxu" will run, and then the words "Cang" and "Xu" will slowly rise

...If the elder brother wants to open the Sheng door, he pressed the word "cang" and to open the Hua door, he pressed the "xu". The elder brother must remember that the order in the middle cannot be different at all. Once the "cang" and "xu" jump out of the box, he must press it as soon as possible... If the "cang" character is the Sheng door, the things in the box will not move as they are. If the "cang" character is the Hua door, it will be transformed into nothingness. It will turn into nothingness..."

After hearing Xiyan's endless speech, Xu Ke couldn't help scratching his forehead and his neck. He didn't know why, but he was embarrassed to ask more details. For a moment, he had to stand there, his eyes stunned...

Xi Yan laughed again, "Brother, I can open it for you, but this place is wrong, and it is not convenient for me to cast spells here. If the old man knows, I will be punished! Big brother should take the iron box home and think about it slowly..."

"This...this..." Xu Ke said in a naughty way. But he was thinking in his heart: "Just just now, Brother Li asked me to figure out how to open the iron box by myself. Now, even if you Xiyan told me, I don't know how to open it! Brother Li, Brother Li, what is the purpose of giving me an inexplicable iron box?! What is it hidden inside? Apart from destroying my good sword, what should I do with this Sixiang Cangxu!"

Seeing that Xu Ke was quite worried, Xi Yan knew that he had not fully understood what he said. He thought for a moment, then suddenly slapped his little head and said with a smile:

"Big brother, I remember it! The old man also told me a simple method, saying that if a person who has practiced the profound Taoism can only exhale true energy from his palm and brush the iron box from the air, then the "Four Symbol Cangxu" will naturally produce a sense, and the words "Cang" and "Xu" can also be raised... However, those who practice the profound Taoism are all experts in Shushan... Big brother, I don't know if it's OK..."

"Okay! Thank you Xiyan. It's not too early, and my elder brother is going back. Let's think about it carefully when I get home! I'll come to play with you again if I have time in the future..." Xu Ke was dizzy after hearing it for a long time, and this last sentence seemed useless. He didn't want to waste time any more. Now that he knew that the poison had been resolved, he simply remembered that there were still many things to do, the most important thing. At this time, Hu Yiyi and Shu Hentian didn't know where they were. What if there was any danger?

Xu Ke left Xi Yan and walked out of the Taoist temple. Unexpectedly, after he walked dozens of steps, the little Taoist boy behind him chased after him again and said to Xu Ke with a smile:

"Big brother, actually, Xiyan... Xiyan has something to ask for!"

"Oh, I didn't expect that I could still serve my little brother Xiyan... Say it! What's the matter? As long as the eldest brother can help, the eldest brother will definitely agree!" Xu Ke stopped and asked with a smile.

"That's...this...that's the one Xiyan just talked to his elder brother...that master who uses swords is Xiyan's good friend. He once taught Xiyan more than a dozen sword techniques, and they are all very useful...He is a big good man! He is pretty and his sword skills are quite brilliant!...Xiyan admires him very much! Big brother... One day if you see him, you must be good friends..." Xiyan said intermittently.

Seeing that Xiyan was talking nonsense and couldn't explain the key points at all, Xu Ke interrupted: "Xiyan was thinking of letting his elder brother know the master who used swords. It would be better to become a good friend, right? OK! I understand! I will follow Xiyan to visit the master in the future..." After Xu Ke said that, he turned around and left again...

"Hey! Hey! I haven't finished speaking yet, big brother... don't leave now!" Xiyan hurried forward, grabbed Xu Ke's left hand again, and shouted.

Xu Ke had no choice but to stop again. At this time, he simply stopped talking and looked at Xiyan, waiting for Xiyan to finish speaking. At this moment, the expression on his face actually clearly showed a sentence: "You little talkative person! It seems that your master gave you the name "Xiyan", which is really the right one..."

This time, Xiyan stopped talking nonsense. He let go of Xu Ke's hand, bowed to Xu Ke, but a sad expression appeared on his face. He sighed and said sadly:
Chapter completed!
