As soon as it was dark, the three of them put on night clothes and stood guard outside the palace wall, and finally got beaten by more drums, Xu Dong took out the water and soil escape card from the treasure bag, and sneaked into the Dragon City Palace with Yaqian and the 'medicine' boy.

Under the light of the palace lanterns, all kinds of rare palace trees cast sparse shadows, and the three of them quickly hid in the shadows of the trees, dodging the patrolling palace guards and slowly went deep into the palace.

The 'medicine' boy was the guide in the front, and Xu Dong and Yaqian followed behind, passing through a royal 'flower' garden covering an area of thousands of hectares, and bypassing a huge rockery, to an open and bright place.

"Shhhh After Xu Dong and Yaqian followed, the 'medicine' boy pointed to a black shadow standing not far in front of him and said, "That's it, that tall thing is the Dragon King Pavilion." ”

Xu Dong 'rubbed' his eyes and saw that it was an attic with flying eaves and corners, ancient fragrance and ancient 'color', and the attic was no more or less than thirteen floors, needless to say that it was the Dragon King Pavilion.

"It's too far away to see anything clearly, senior, can you take us around behind it so that we can observe its structure more closely. ”

The 'medicine' boy nodded and said, "You come with me, I know a place that is closest to the Dragon King Pavilion." ”

Xu Dong and Yaqian followed the 'medicine' boy forward, and the three of them cautiously crossed a tree-lined avenue, and then crawled into a bush, which was only about ten steps away from the Dragon King Pavilion.

"Senior, you and my lady are lying here and not moving, and I will go into the attic to visit. ”

The 'medicine' boy whispered, "There are palace guards guarding the 'door' of the attic, you should be careful, don't let them find out, otherwise you will 'get' a 'chicken' and a flying egg." ”

Xu Dong nodded, he quickly flashed into the 'yin' shadow cast by the attic, carefully checked the movement around him, except for finding that there were two guards guarding the 'door' of the attic, and no one was seen anywhere else.

He waited patiently for a while, and the two guards guarding the 'door' could not support themselves, and began to sit on the ground and doze off with their arms in their arms, and he walked lightly to the back of the attic, "Whoosh." He jumped up to the second floor of the attic.

Xu Dong walked around this attic, trying to find a 'door' window to enter inside, but found that this attic had no 'door', and there was no window, and the walls were made of 'flower' granite, which was difficult to penetrate even with wall penetrations.

He flew up to the third floor, and this floor, like the second, had neither a door nor a window, so he had no choice but to jump to the fourth floor.

When he walked up layer by layer, until he reached the thirteenth floor, he still didn't find a 'door' window to enter inside, it turned out that this Dragon King Pavilion had a 'door' except for the first floor, and there were only thick stone walls on each floor.

Xu Dong hated that he hadn't learned the wall-piercing technique, otherwise he would have entered it by now, and it seemed that some basic spells were still indispensable, and he might be useful sometime.

Of course, it's not that he doesn't have a way to break through this wall, that is, to use the Thunder Spirit Technique he practiced earlier, but this technique is too 'moving', and it will overturn the entire palace in the middle of the night.

Xu Dong came down from the attic and went to the bushes to discuss a solution with the 'medicine boy', and the 'medicine' boy said, "Since this is the case, the only way is to anesthetize those palace guards, and then go through the main 'door' to enter." ”

As he spoke, he took out a blow pipe from his pocket and put a few flying needles in the blow pipe, and when these flying needles were blown out, he could immediately turn the two guards into dead people.

Yaqian waved her hand at the 'medicine' boy, "This method can't be used, I have carefully observed, every once in a while, a team of patrolling palace guards will come over, and when they see these two guards dozing off, they will immediately wake them up." ”

"And I've noticed that there is more than one team of guards patrolling the palace, and if they find that these two guards have been anesthetized, we won't be 'exposed' ourselves." ”

When the 'medicine' boy heard Yaqian say this, he immediately became anxious, "That'...... How do we do that? ”

Xu Dong thought to himself, in such a forbidden place in the palace, in order to protect the safety of the royal family, the king of Longcheng does not know how many masters are ambushed in the palace, once there is a little trouble, it will be a big trouble.

Just as he was turning his mind to figure out a way, a pair of patrolling palace guards walked in front of the Dragon King Pavilion, and the leader stepped forward to greet the two guards, "Look, don't fucking doze off." The two guards nodded.

He said in his heart, yes, yes, he noticed that the two guards were wearing that kind of windproof hat, and almost half of their faces were covered, and the palace guards couldn't see their faces clearly.

Hurriedly discussed with the 'medicine' boy, "Senior, I don't think it's better to do this, drag those two guards into the bushes after turning them over, you and my lady are wearing their clothes and guarding the 'door' of the attic, and I will go into the attic to find the scriptures." ”

The 'medicine' boy 'touched' his head and said, "Although there is a danger of being recognized by the patrolling palace guards, it has to be like this, otherwise it will be almost dawn after a while, and I still can't think of any way to get out." ”

He blew the blowpipe at the two guards, and the flying needles in the blowpipe pierced the bodies of the two guards, and the two guards fell to the ground as if they were drunk, and Xu Dong hurriedly went up and dragged the two guards into the bushes.

The three of them started to peel off the clothes and hats of the two guards together, and the 'Yao' boy and Yaqian hurriedly put on the clothes and hats, taking the place of the two guards, and Xu Dong opened the 'door' into the first floor of the Dragon King Pavilion.

Due to the lack of design of 'doors' and windows, the attic was dark and mushy, and it took Xu Dong a while to get used to it, only to see several rows of tall cabinets inside, and all the cabinets were stacked with scriptures.

Xu Dong couldn't help but secretly complain, how easy it was to find out the "Commentary on the 'Medicine' Sutra" from the piles of scriptures, but Xu Dong had no other way, only a cabinet to rummage through carefully.

He finally finished digging through a cabinet, which contained only a few commonly seen books, which seemed to him to be of little value, and he wondered why the King of Dragon City had collected them.

After rummaging through the second cabinet, Xu Dong's patience was exhausted, and he never wanted to touch the third cabinet again, but he knew that he couldn't help himself, so he had to continue to rummage through it calmly.

It took almost an hour for Xu Dong to finish the first floor of several rows of cabinets, but he didn't see the shadow of the "Commentary on the 'Medicine' Sutra".

He thought, it should be a little clever to do this, this Dragon King Pavilion canon must have a characteristic, or a catalog of the canon or something, otherwise, those who manage the scriptures want to find this book by themselves, and it will not be easy to find it.

It would have been much easier to find the characteristics of the canon, or to find the bibliography, and then to find the Commentary on the 'Medicine' Sutra, so he changed his method and let go of the general places to find the key points.

He no longer turned over the neatly stacked scriptures, and paid special attention to loose places and locked cabinets, because such a precious 'medicine' scripture was either often turned over or kept away as a treasure.

Of course, it was better to find a bibliography or something, and it was easier for him to go directly to the cabinet to pick up the books according to the bibliography, but he searched up layer by layer until he found the thirteenth floor, but he could not find what he was looking for.

"Alas. He sighed heavily, sat on the ground, and his heart was extremely gray, and it seemed that he would not be able to take away the "Commentary on the 'Medicine' Sutra" today.

"Bang, bang, bang, bang. The sound of the gong of the fourth watch of the husband came into the attic, and it should be dawn in a while, Xu Dong thought of Yaqian and the 'medicine' boy who were guarding the 'door', they must be in a hurry at this time.

The choice he is facing now is whether to continue to look for it or give up, there is undoubtedly a risk in continuing to search, if he can't get out of the Dragon City Palace before dawn, then the three of them will ...... He didn't dare to think about it anymore.

Damn "Commentary on the 'Medicine' Sutra", where are you hiding.

What to do.

Give up or keep looking.

Xu Dong's mind was like a flywheel installed, spinning rapidly, but it suddenly got stuck.

If he can't complete the task assigned by the 'Medicine' King this time, it will be impossible for him to obtain the seeds of the 'Guiding Thunder Grass' in the hands of the 'Medicine' King, and his and Yaqian's trip to Wolong Valley will be in vain, obviously, this is not the result he wants.

"It's not just for the two of you, I'm sending the 'medicine' boy with you, to find the 'Medicine' Sutra Commentary among the 50,000 scriptures, it may be easier to have the 'medicine' boy to help. ”

Xu Dong's ears echoed the words of the 'medicine' king, he smacked and 'touched' this sentence several times, and finally smacked the 'touch' a little taste, he had an idea, and quickly ran to the bottom floor of the attic.

As soon as he opened the 'door' and appeared at the entrance of the 'door', the 'medicine' boy and Yaqian ran towards him.

"Well, did you find the book? ”

"Xianggong, I found the "Commentary on the 'Medicine' Sutra", it's been the fourth watch, let's get out of the palace quickly. ”

"Alas. Seeing that Xu Dong was empty-handed, the 'medicine' boy let out a long sigh.

Yaqian's face suddenly turned pale, as if someone had 'pumped' the meridians of her body, and the whole person was paralyzed weakly.

"'Medicine' Boy senior, this thing still depends on you to succeed, you quickly enter the Dragon King Pavilion and find out that damn book, time is running out, you will come out immediately after you find it, we will leave the palace before dawn." ”

"Ah, what. The 'medicine' boy was stunned, "You haven't been able to find it for most of the night, what can I do to find it." He shook his head, "I think it's better to forget it, let's get out of the palace quickly." ”

"You can do it, you can do it. Xu Dong said, "The 'Medicine' King also knows that you can do it, so he sent you with us." ”

The 'medicine' boy couldn't turn around for a while, "What do you say, what do you do, you can do it, you make it clear." ”

"That's right. Xu Dong said, "Senior, haven't you been a 'medicine' boy all your life, your nose must be the most sensitive to 'medicine' incense, and that scripture has been 'dealing' with 'medicine' herbs for many years like you, so ......"

He was afraid that the 'medicine' boy would not understand, so he tried his best to spit out the words clearly, "The Dragon City Palace regards that scripture as a treasure, as long as they are equipped with spiritual 'medicine', they will definitely move out of that scripture, so that book must be stained with a heavy smell of 'medicine'......"

"I see, don't say it. The 'medicine' boy interrupted him, "You mean that even if this scripture is hidden in tens of thousands of other books, I can find it at once with my sensitive nose." ”
