"Xiyan, what's the name of this iron box...... You haven't said it yet," Xu Ke looked at Xi Yan who was jumping in the sun, and asked with a smile.

"Ahh......h It's boxy, each side is six inches, and there is something else in the box, don't look at it from the outside, it looks like a small box, inside, it's very big......" Hearing Xu Ke's question, Xiyan touched his chin embarrassedly and replied.

Xu Ke has been holding this iron box in his hand, and along the way, he has found that the weight of this box is sometimes heavy, sometimes light, and it has been unknown before, but now he has realized it after listening to Xiyan's explanation. So he asked:

"Why did your master say what a three-star box it was......? And let me open it myself, is there anything rare in this box? I see that there is not even a crack on the outside of this box, how can I open it?"

Xi Yan took the "Four Elephants Cangxu" from Xu Ke's hand, and while playing with it casually, he pouted and said:

"The old man is really eccentric! I have been with him for more than ten years, and I have never had a decent baby. He just met you today, and he gave you this treasure of the town...... Hmph, you eccentric stinky old man, bad old man, bad old man! I'm not going to get you anything to eat tonight!"

Xu Ke hurriedly smiled: "Little brother, if you like it, this ...... I'll pass it on to you, so don't delay your master's dinner......

Xi Yan smiled and said: "Big brother, I'm talking about playing! This 'Four Elephants Cangxu' is a gift from the old man to the big brother, I don't dare to ask for it! Besides, there are good things hidden in this box, and the big brother won't accept it, but he will regret it...... Big brother, don't worry, the old man's dinner, I hope I will do my best, and I'll make him a bowl of 'senna soup big tonic soup' for him in a while...... Hee-hee-hee!"

Xu Ke had no choice but to smile, he had a lot of questions in his heart, but he didn't say anything at this time, just because, the few questions he asked before, this little Taoist boy still hasn't replied......

Seeing that Xu Ke no longer spoke, and did not ask him what the "Senna Leaf Tonic Soup" was, Xi Yan suddenly felt bored in his heart, so he returned the "Four Elephants Cangxu" to Xu Ke's hands, and said:

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

Xu Ke said in his heart that this little Taoist boy's mind was really imaginative, why did he ask about the matter of Tianbao Pavilion again?

"I've been to this Heavenly Treasure Pavilion a few times, what's the ...... Is Xiyan's little brother also familiar with the people there?"

Xi Yan said: "This Tianbao Pavilion is one of the three pavilions in the world, how can I know the people there? It's just that I heard from the master that he has a book in the Tianbao Pavilion called "The Directory of Heavenly Treasures." The book records all the powerful weapons, Taoist weapons, and magic weapons in the whole world, and the pavilion masters of the past dynasties continue to supplement and collect, so that the "Tianbao Directory" can be called the most complete collection of various utensils throughout the ages. In the "Tianbao Directory", all the powerful weapons in the world are divided into five types, which are called 'one-star grass weapons', 'two-star medium weapons', 'three-star magic weapons', 'four-star spiritual weapons', and 'five-star artifacts'...... It's a pity, according to the book, most of the powerful weapons are only one-star or two-star, and there are very few that can be ranked above the 'three-star magic weapon'......"

"Venerable Master's 'Four Elephants Cangxu' is a 'three-star magic weapon'! This gift ...... But it's too precious......" Xu Ke said.

Xi Yan said: "So-so, big brother, didn't you also give the old man a piece of the East China Sea spirit stone? That spirit stone is an authentic three-star magic weapon! The so-called coming and not being rude, the old man does not lose money in this business, and he does not lose ...... money."

Xu Ke said in his heart: "No wonder, I heard Yu Lu Weng and Suzhou Land Gong talk about 'two-star' and 'three-star' and the like, it turns out that it is all based on his Murong family's book, it seems that this "Tianbao Directory" is really extraordinary......

Seeing that Xu Ke was thinking to himself, Xi Yan immediately pointed to the sword on Xu Ke's back, and asked with a smile:

"Big brother, do you know how many stars this Kunwu sword on your body ranks in the "Tianbao Directory"?"

"Presumably it's always above the two-star medium weapon...... Xu Ke replied casually.

"Hahaha! I'm laughing to death! That Kunwu sword is well-known, but in fact, it has only been given the title of 'one-star grass weapon'!" Xi Yan smiled with a clapped palm.

"This ......" Xu Ke couldn't help but secretly wondered: "My Kunwu famous sword, blowing gold and breaking iron, has a sharp end, how did it become a 'one-star grass weapon'?! According to this speculation, I really don't know what is so powerful about the 'Four Elephants Cangxu' that ranks among the 'three-star magic weapons'......"

Xi Yan seemed to see Xu Ke's thoughts, and then said:

"Big brother, don't you think that your sword is sharp, you should try the iron box in your hand?"

"As soon as my Kunwu sword comes out, won't this box fall apart?" Xu Ke asked rhetorically.

"Hahaha, big brother, just draw your sword and give it a try, you'll know if you try......" Xiyan said with a smile.

Xu Ke didn't believe it in his heart, he said in his heart that my Kunwu sword was only drawn 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 has the heart not to draw the sword, but after all, it is also the heart of a young man, and he can't help but say that he is excited, so he put the "four elephants cangxu" on the ground, and pulled out the Kunwu sword from the back, not daring to be lucky, just holding the sword towards the corner of the iron box and gently slashing it......

Xu Keman thought that the iron box must have been cut off a corner, and after a closer look, he saw that the iron box was placed on the ground steadily, not to mention that a corner was cut off, and there was not even a scratch.

Xu Ke looked at his Kunwu sword again, but he couldn't help but gasp, only to see that the edge of the upper edge of the blade had been broken out of a cut, although the cut was not big, but it seemed shocking at this time......

"Hahahaha! I'm laughing to death! Big brother, now I know that Xiyan didn't lie to you! Fortunately, you didn't have the true luck just now, if you focus on your strength, your sword given by the emperor will have to be broken...... Hahaha!" Xiyan laughed, laughing, and stomping his feet and clapping his hands, as if he had picked up a treasure, and he was inexplicably excited.

Xu Ke sighed, and had to return the sword into the sheath. Although this Kunwu sword has only been with him for more than a month, it has helped him save the day several times, and Xu Ke has already felt grateful to it in his heart. Now, he saw that his "love sword" had been broken for no reason, and his heart ached inexplicably for a while, but at this time, there was no other way than to regret that he had the right time to impulsively take out the sword......

"Ahem...... Big brother! Xi Yan knows a master who uses swords, he has several famous swords at home, next time, Xi Yan will ask him for one to give to his big brother......! In fact, it looks fancy and jeweled, and when it comes to the enemy, it is useless......"

Xu Ke picked up the "Four Elephants Cangxu" on the ground, took it and left, his heart was still sinking in the "pain of breaking the sword" and couldn't extricate himself, just hoping to think of a way to repair the gap in the blade.

Xi Yan chased after him, and said with an aggrieved face:

"Big brother, I'm sorry! I shouldn't have played this joke with you just now, don't be angry...... Well, I'll tell you how to open the 'Four Elephants Cangxu', the master didn't let me say it, but I'll say it now, even if I make up for it, okay?"

At this time, the two had already walked to the gate of the Xuandu Temple, Xu Ke couldn't help but stop, he wanted to say, "Since the respected teacher won't let you speak, it's better for you not to say it"; but at this time, when he saw the expression on Xiyan's face, he was aggrieved and pitiful, and he couldn't bear it, and secretly thought how could I be angry with a child?

"The big brother is not angry, it is just a sword, and if it is broken, it will be broken...... Xiao Xiyan, then you can tell me how to open the iron box......"

Xi Yan saw Xu Ke with a smile on his face, so he also smiled and said, "Hmm...... These four elephants are empty, the four elephants are the meaning of the four poles of heaven and earth, the east is the green dragon table Shaoyang main spring, the west is the white tiger table Shaoyin main autumn, the north is the Xuanwu table old yin main winter, and the south is the red bird table old yang main summer. Cang is the meaning of greatness, and as for this emptiness, it is the meaning of infinity. If the big brother wants to open the box later, he needs to find a secluded place, and slowly rub the four sides of the iron box with his true qi, and you will see that the four sides of the box will show the appearance of four holy beasts, and the two sides will reveal the words 'warehouse' and 'void' respectively. ”

After a pause, Xi Yan said again:

"The eldest brother needs to 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 have to first rotate the side of the green dragon in the order of the southeast, then the side of the vermilion bird in the order of the north and south, then the side of the basalt turtle and snake in the order of the north and west in half of the order, and finally the side of the white tiger in the order of the west and the east to the end...... Then, the machine in the 'Four Elephants Cangxu' will run, and then the words 'Cang' and 'Void' will slowly rise...... If the eldest brother wants to open the door, he will press down the word 'cang', and if he wants to open the door, he will press the word 'virtual'. The big brother should remember that the order in the middle cannot be half a point apart, once the words "cang" and "imaginary" jump out of the box, you must press it as soon as possible...... If you press down the word "cang" is the door, the things in the box will be untouched and come out of the whole body; if you press the word "void" is the door, at this time, no matter what is hidden in the box, it will turn into nothing, turn reality into nothingness, and become a mass of nothingness......"

Listening to Xi Yan's gushing words, Xu Ke couldn't help but scratch his forehead and scratch his neck......

Xi Yan smiled again: "Big brother, originally, I can help you open it, but this place is not right, it is not convenient for me to cast spells here, in case the old man knows, I will have to be punished! Big brother still take the iron box home, and then think about it slowly......

"This ...... This ......," Xu Ke said with a sigh. But he was thinking in his heart: "Just now, Brother Li still wants me to figure out how to open the iron box by myself, and now, even if you tell me about it, I still don't know how to open it! Brother Li, Brother Li, what is the purpose of you giving me an inexplicable iron box? What is there hidden in it? In addition to destroying my good sword, these four elephants are empty, what am I doing with it!"

Xi Yan saw that Xu Ke was quite worried, knowing that he had not fully understood his words, he thought for a moment at the moment, suddenly patted his little head, and said with a smile:

The old man also told me about a simple method, saying that if a person who has practiced the advanced and profound Dao Fa only needs to spit out the true qi from the palm of his hand and flick the iron box in the air, then the 'Four Elephants Cang Xu' will naturally give birth to induction, and the words 'Cang' and 'Void' can also arise...... It's just that those who practice the profound Dao are all masters of Shushan...... Big brother, I don't know if it's okay......"

"Okay! Thank you, Xiyan, it's not too early, big brother is going back. When I get home, I'll think about it again! When he is free, I'll come to play with you again......" Xu Ke listened to it for a long time, dizzy for a while, and this last sentence seemed useless. He didn't want to delay any longer, now that he knew that the poison had been resolved, he remembered in vain that there were still many things to do, the most important thing, at this time, Hu Yiyi and Shu Hatian still didn't know where they were, what if there was any danger?

Xu Ke said goodbye to Xiyan and strode out of the Taoist temple. didn't want him to walk dozens of steps, but the little Taoist boy behind him chased after him again, and said to Xu Ke with a smile:

"Big brother, actually, Xiyan...... I hope I have one more thing to ask for!"

"Oh, I can't believe that I can still serve my little brother Xiyan...... As long as the eldest brother can help, the eldest brother will definitely agree!" Xu Ke stopped and asked with a smile.

"That's it...... That's it...... The ...... that Xiyan just told his big brother about The master who used the sword, he was a good friend of Xiyan, and he had taught Xiyan more than a dozen swordsmanship, all of which were very useful...... He's a very good man! he's good-looking, and he's pretty good at swordsmanship...... Xi Yan admires him very much! Big brother...... If you see him one day, you will surely be good friends......" Nozomi said intermittently.

Seeing that Xi Yan was talking without a match, and he couldn't get to the point at all, Xu Ke interrupted: "Xi Yan wants to let the eldest brother get to know the master who uses the sword, and it is best to become good friends, right? Okay! I know! I will follow Xi Yan to visit that master in the future......" After Xu Ke finished speaking, he turned around and left again......

"Hey, hey, I'm not done yet, big brother...... Don't leave yet!" Xi Yan hurriedly stepped forward, grabbed Xu Ke's left hand again, and shouted.

Xu Ke had no choice but to stop talking, and then he simply stopped talking, just looked at Xi Yan, and waited for Xi Yan to finish speaking. At this moment, the expression on his face actually showed a sentence very clearly: "You little talker! It seems that your master gave you the name 'Xiyan', but it was really the right one......

This time, Xi Yan was no longer verbose, he let go of Xu Ke's hand, bowed down to Xu Ke, but showed a sad expression on his face, sighed, and said gloomily:

"This friend of mine, his name is Li Junxian, and the official worships General Zuo Wuwei, and now he is imprisoned in the Tsing Yi Wei Prison. He was wrongfully imprisoned, and now his life is in danger, Xiyan begs his eldest brother to save him!"
