Chapter 656 The Key of the Artifact
"This is... a keyhole?" Li Canghai asked in surprise.

The monk and his party nodded, and said excitedly: "This Shangtong magic box is simply amazing! I have been immersed in the art of heaven for decades, and I have never seen such an exquisite structure. This Shangtong magic box is only When the two become one, the true colors will be revealed; when they are divided, they will become two;

Li Canghai and others were also amazed by the emotion of the monk and his party.

Being able to make such a mechanism box, Mozi is indeed a fairy-like figure.

"I don't know if Master can open Shang Tong's magic box?" Li Canghai asked.

The monk and his party frowned. He stroked his gray beard, shook his head and sighed: "I only found out its inherent form, but I have no idea how to open it."

"According to the master's ability, you can't open the magic box?" Li Tan asked in surprise.

The monk and his party shook their heads and said, "This Shangtong magic box is extremely delicate in structure, and the internal mechanisms are ever-changing, with no rules to follow. Unless you find the key, it will be difficult to open this magic box."

"Is there no other way?" Li Tanjian asked with a frown.

The monk and his party shook their heads again and sighed: "Other than this, there is no other way. If the old monk is younger, he may be able to open it, but now, the old monk is dying, and his head has become much duller, and the old monk is powerless. gone."

"Master, can this magic box be viewed next?" Li Canghai who was staring at the magic box suddenly asked.

The monk and his party nodded and said, "Blesser, please do what you want."

Li Canghai took the magic box in his hand, looked at it carefully over and over again, and then focused on the keyhole of the magic box.

The keyhole is located directly above the magic box, and it is a crescent-shaped depression that is one finger long and short.

Li Canghai carefully observed the keyhole, and suddenly had a feeling of déjà vu.

"Cang Hai, what did you think of?" Seeing him lowering his eyebrows in deep thought, Li Tan asked curiously.

"This depression gives me a feeling of déjà vu, as if I've seen it somewhere before." Li Canghai said while staring at the box.

"So, do you know the key to the magic box?" Conan asked in surprise.

Li Canghai didn't speak, he took Shang Tong's magic box, walked to a chair and sat down, then stared at the magic box closely, quickly searching for relevant memories in his mind.

Half an hour later, Li Canghai jumped up suddenly, and he cried out: "I remembered!"

"What did you think of?" Several people hurriedly looked at him.

Li Canghai glanced at Conan and Fushimi Hirohito, and said deeply: "I remember seeing it somewhere, Brother Conan and the Sixth Prince have seen that thing before!"

When Conan and Fushimi Hirohito heard the words, they looked at each other in surprise, and there was a puzzled look in their eyes at the same time.

"We have seen it before? What is that?" Conan asked puzzled.

"Qiong Quyu, one of the three great artifacts!" Li Canghai said without a word.

"What? It's Qiong Quyu?" Conan and Fushimi Hirohito almost jumped up when they heard the words.

Li Canghai nodded heavily, and said, "Don't you think that the shape of Qiongquyu is very similar to the dent of this key? If my guess is correct, Qiongquyu is probably the key to Shangtong's magic box! "

"This...how is this possible? Qiong Quyu is my Dongpu artifact, how can it be the key to open this magic box?" Fushimi Hirohito stared in disbelief.

"Cang Hai, why do you think so?" Li Tan asked calmly with his hands behind his back.

"Intuition!" Li Canghai frowned and said, "I think if the secret of longevity is hidden in the magic box, it must be related to the three great artifacts. Xu Fu went to Dongying back then, but he didn't take the two brocade boxes with him at the same time. He must be worried. Someone in Dongpu discovered the secret. Therefore, one of them was left in the Central Plains."

The monk and his party nodded, and said, "It's somewhat possible, as long as Shang Tong's magic box doesn't reveal its true colors, even holding the key is useless."

"It's not too late, quickly bring the magic box into the palace!" Li Tan said immediately after thinking about it.

Everyone's spirits were lifted, no matter whether the theory of longevity was credible or not, the secret hidden in this magic box made them very curious.

The three major artifacts are stored in the Sanqing Hall in the Daming Palace, and Li Canghai has a token given by the emperor, so he can travel unimpeded.

A few people rode in a carriage and rushed to the imperial palace at high speed. After entering the imperial city, they went straight to the Sanqing Palace.

The three artifacts are related to the secret of longevity, so Li Longji attached great importance to them and sent the most elite Longwuwei to guard them.

The three artifacts were stored in front of the statue of Sanqing God in the main hall of Sanqing Hall. After Li Canghai and others entered the hall, they went directly to the altar and picked up Qiongquyu.

Qiongquyu is shaped like a crescent moon, and its whole body is emerald green. It is indeed very similar to the depression on Shangtong's magic box.

Li Canghai picked up Qiongquyu, let out a deep breath, and carefully placed Qiongquyu in the depression of the magic box.

There was only a click, and the magic box was opened in the shape of a lotus flower.

"By God, Qiong Quyu can really open the magic box?" Fushimi Hirohito said from ear to ear in shock.

After opening the magic box, everyone found that there was only a palm-sized jade slab inside, and nothing else.

"What is this?" Conan asked confusedly.

Li Canghai shook his head, and after thinking about it, he took the jade slab in his hand and looked at it carefully.

This jade slab is about the size of a palm and about an inch thick, like a piece of crystal clear ice.

Li Canghai lifted the jade to have a look, and found that there were still some lines engraved on the jade slab.

"My lord, what do you think of the lines engraved on this jade board?" Li Canghai said after handing the jade board to Li Tan.

Li Tan looked at it in his hand, and pondered: "This seems to be some kind of circuit diagram, but it is somewhat specious."

Conan frowned and said, "Strange, why is this only stored in this box? Brother Li, do you still think it has something to do with the secret of longevity?"

Li Canghai didn't speak. He stared at the jade slab for a long time before he said, "This magic box of Shangtong can only be opened with Qiongqu jade. It's no coincidence. I think it has something to do with the secret of longevity." It is related, but what kind of relationship it is, is unknown.”

After thinking about it, he said, "My lord, I want to stay here alone for a while and see if I can find some clues from the three artifacts."

Li Tan nodded and said, "Alright, since that's the case, then I won't bother you."

After speaking, Li Tan, Conan and the others left the Sanqing Hall on their own initiative.

Inside the Sanqing Hall, Li Canghai was sitting on a futon, and in front of him were the Qiongquyu, the Grass Pheasant Sword, the Yata Mirror, and the sapphire board.

Li Canghai sat cross-legged, staring at the things in front of him, lost in thought.
