Chapter 437

The bronze boxes containing the secret of the Seven Luminaries of the Azure Dragon were incredibly sturdy. Of course, if Su Xuan didn't care about martial ethics, with his strength, he could still destroy the boxes, but he didn't do so. No one knew if the boxes contained self-destruct devices; if he operated them improperly and the contents were destroyed, the loss would outweigh the gain.

There was only one such set in the whole world; once destroyed, it could never be restored.

More importantly, the seven parts of the Seven Luminaries of the Azure Dragon were all indispensable.

Su Xuan was also not sure if rashly destroying one of them would allow him to crack the secret of the Seven Luminaries of the Azure Dragon, so he did not take that risk, choosing instead to slowly crack the objects.

On the side of the bronze box, in the middle of the gear-shaped star pattern, there was a protruding circular button. It was like the combination lock of a safe in later generations. Su Xuan carefully recalled the music he had heard from the Phantom Sound Box earlier and began to try to input the password to open the bronze box.

This process was actually not troublesome.

Not only because the Yin-Yang School had studied the Seven Luminaries of the Azure Dragon deeply, but also because Su Xuan was proficient in many strange techniques, and he was not ignorant of the methods of Qimen Qimen Dunjia. He was quite proficient in their mathematical and profound principles, especially his expertise in the art of "Star Numbers," which was countless times more profound than the Yin-Yang School's Astrology Laws.

Astrology Laws, in the original story, were an important technique for cracking the Seven Luminaries of the Azure Dragon.

Su Xuan understood "Star Numbers," which were even more powerful than Astrology Laws, and using them to comprehend the secret of the Seven Luminaries of the Azure Dragon, he soon understood the secret.

Although the Seven Luminaries of the Azure Dragon were widely spread throughout the world and contained deep secrets, in the end, they were just seven password boxes.

After obtaining the key to cracking the password, the "Phantom Sound Box," it was no longer a problem for Su Xuan to crack them.

Before long, all seven boxes were opened.

Before opening the boxes, Su Xuan had guessed what was hidden inside, but when he really saw clearly what was inside, he was stunned.

Because, hidden in the seven boxes were seven pieces of tortoise shell.

And the tortoise shells were broken.

This made Su Xuan somewhat surprised.

He took out the seven pieces of tortoise shell, and after touching them with his own hands, he felt the extraordinary nature of the shells. There seemed to be a unique power contained within them, a power that made them incredibly sturdy, almost immortal.

Coupled with the sturdy bronze boxes containing them, presumably the creators of the Seven Luminaries of the Azure Dragon had already planned for these objects to circulate in the world for hundreds or thousands of years; otherwise, there was no reason for them to be so sturdy.

Su Xuan carefully examined the tortoise shells and discovered that there were many patterns on the back of the broken shells. These patterns were not natural but were engraved by someone later.

He placed the seven pieces of tortoise shell together and pieced them together.

Instantly, they formed a complete tortoise shell.

On the back of the shell, the patterns wound around, forming an incredibly profound map, and some tiny characters were written on the map.

Those were extremely ancient characters.

Su Xuan carefully identified them and recognized some of the content, which were surprisingly characters like "Penglai, Fangzhang, Yingzhou."

"The three fairy mountains overseas; so, is this a sea chart?"

Su Xuan was a bit surprised, and then he couldn't help but examine the tortoise shell.

"Don't tell me this tortoise shell is the shell of the legendary Great Ao?"

Su Xuan complained inwardly.

Mentioning the three fairy mountains overseas, he first thought of the legendary story of the Longbo giant fishing for the Ao. It is said that in the original eastern sea area, there were five fairy mountains. The roots of these five mountains were not connected, and they often moved up and down with the waves of the tide, never stable for a moment.

The gods and sages hated this and reported it to the Heavenly Emperor. Fearing that the fairy mountains would drift to the western extreme and break the balance of heaven and earth, causing the residents of the mountains to lose their homes, the Heavenly Emperor sent the North Sea God, Yu Qiang, to drive fifteen giant Ao, divided into five groups, to support the mountains with their heads. In the blink of an eye, sixty thousand years had passed, and the five fairy mountains began to stabilize and no longer drift. However, a giant from the Longbo country took a few steps and arrived at the location of these five divine mountains, and with one hook, he caught six giant Ao. Because the Longbo giant took away the six Ao, the "Daiyu" and "Yuanqiao" mountains lost the giant Ao that carried them, drifted to the North Pole, and sank into the vast ocean. From then on, only three fairy mountains remained.

In the "Heavenly Questions" chapter of the "Chu Ci" written by Qu Qu Yuan of the Chu State, a question was raised about this: "The Ao carried the mountains, where did they go?"

It can be seen that this legend has been circulating in the world for a long time.

Seeing the words for the three fairy mountains overseas on the sea chart on the tortoise shell, and since it was a tortoise shell, Su Xuan couldn't help but think of this.

Immediately, he shook his head. How could this be the shell of a Great Ao? A Great Ao could carry mountains, and its size would be countless times larger; this was just an ordinary tortoise shell.

"However, I didn't expect that the three fairy mountains overseas actually exist!"

He was not surprised that the treasure of the Seven Luminaries of the Azure Dragon was hidden on the sea; after all, in the original story, the Yin-Yang School used the power of the Qin State to build the incredibly huge Mirage, just to go out to sea.

The only thing Su Xuan was truly curious about now was whether these three fairy mountains were fairy mountains where gods truly lived, or... some islands named after fairy mountains?

267

For example, some island country?

"But even with the sea chart, it is not an easy thing to find the location of the fairy mountains!"

Su Xuan recognized the reality again.

If the fairy mountains referred to some island country, that would be fine, but he feared it referred to the true fairy mountains.

The latter seemed incredible, but in fact, there was still a possibility.

The main reason was the "Yellow Stone Heavenly Book" and the "Nine Heavens Mysterious Maiden" who left this book in the human world. Through the Yellow Stone Heavenly Book, Su Xuan caught a glimpse of the image of the Nine Heavens Mysterious Maiden from the past, and he could be certain that she was not a creature of this world but an existence that broke through the boundaries. Judging from the various methods she displayed, she was very likely a true... immortal!

Since true immortals existed, the existence of fairy mountains was not something incomprehensible.

After carefully looking at the sea chart on the back of the tortoise shell again, Su Xuan slowly put it away.

Although the sea chart was very exquisite, it was not so easy to find the three fairy mountains overseas pointed to by the chart.

Because a crucial thing was still missing.

He had roughly guessed what this final thing was through the characters on the tortoise shell.

The supreme treasure of Shushan—the Divine Tree Fusang!
