This cave is not big, only hundreds of zhang wide, and you can see it at a glance.

What attracts Zhao Di the most is, of course, the stone wall at one end of the cave, the mysterious prohibition.

This place is like an ordinary stone wall, but if you look closely into the Divine Sense, you will find that the Divine Sense cannot penetrate at all.

In addition to this stone wall, there is also an unusually old stone pavilion here, and even a layer of fine moss grows on the surface.

In the stone pavilion, there is a stone bench, a long stone table, a stone table, and a stone piano. It's just that all of this is covered up by moss.

With a wave of Zhao Di's robe, a piece of spiritual light swept by, and the moss of those uu fell one after another, and the stone pavilion returned to its original appearance.

"Sure enough, you need strings!" Zhao Di glanced at the stringless stone qin, and immediately understood what the mortal god and nun said before he died.

"But there is only one groove for the strings of this stone qin, do you want to play it with one string?" Zhao Di was a little puzzled.

If the bitter old monk is not wrong, in order to unlock the prohibition of the stone wall of this cave, it is necessary to play a song "Song of Righteousness", and most of them must be played with this stone qin here to be effective.

No wonder the fallen gods and nuns would deliberately prepare a "Heyu, strings." "It turns out that I already know the mechanism of this stringless stone qin.

There were a lot of things, and the monks and nuns waited for a long time, but they did not explain it clearly to Zhao Di and others, and Zhao Di had already been mentally prepared for this.

It's just a string, how difficult can it be! There are a lot of materials in the Zhao Di storage bracelet, and he is proficient in the way of refining, refining a string, it is not easy!

In the past hundred years, Zhao Di has already refined several strings in case of emergency.

Zhao Di investigated carefully, and found no danger, so he summoned Xuanyuan Yi from the Tower of Babel.

A moment later, Xuanyuan Yi and Yun Mengli both came out of the Tower of Babel, both of them had red circles under their eyes, which made Zhao Di slightly stunned.

He didn't ask much, took out a golden string, handed it to Xuanyuan Yi, and said: "There is a friend who plays a song "Song of Righteousness", presumably that score, and you have already mastered it. ”

"Yes!" Xuanyuan Yi took the strings of the golden silk and placed them on the stone qin, then sat in front of the stone qin, closed his eyes and calmed down.

Zhao Di and Yun Mengli stood quietly aside, not daring to disturb them.

After brewing for a long time, Xuanyuan Yi finally opened his eyes, and his body suddenly exuded a powerful Confucian aura, his expression was solemn, and he began to put his hand on the golden strings and play slowly.

"Ding~dong~Zhengzheng......", after just a few rhythms, Xuanyuan Yi stopped playing, shook his head and said: "This string is not right, it can't play the scale at all." I'm afraid that I won't be able to play the "Song of Righteousness"! This score is special, and if you have to play it with only one string, the requirements for the strings are also special. ”

Zhao Di frowned, and didn't do much, and immediately took out another white jade string and handed it to Xuanyuan Yi.

The latter tried a few times, then shook his head again in the negative.

Zhao Di's heart sank, and in desperation, he had to take out all the strings and let Xuanyuan Yi choose.

Xuanyuan Yi tried one by one, some of the strings only fluctuated a few times before shaking his head and giving up, while others tried to play a section and then stopped.

"Hey, this string seems to be usable!" Xuanyuan Yi suddenly looked happy after playing for a while, and his eyes flashed.

Zhao Di was greatly surprised, because the ruthless strings in Xuanyuan Yi were not the treasures he had refined over the years, but the embroidered iron strings that had been given to him by Mo Youzi many years ago.

Zhao Di had repeatedly studied this string, it was made of common meteorite iron, it was ordinary, and it had no use, so it had been left in the storage bracelet and never used.

Now, because Xuanyuan Yi wanted to try different strings, Zhao Di took out all his strings, and somehow, he took out this iron string easily.

Unexpectedly, this iron string was actually picked by Xuanyuan Yi!

Of course, Xuanyuan Yi will not know the origin of this string, and at this time, he only picked this iron string, mostly because of this iron string, only its specialness!

Zhao Di frowned, and looked at the iron strings in confusion, although he is now cultivating higher and his eyesight is stronger, but he still can't come out, what is so special about this ordinary iron string!

In the sound of the piano, there is a sky-high heroism, suddenly like a single-handed, laughing at the army of millions: suddenly like in the stormy waves, riding alone - green @ color #¥& net - long, heroic and inspiring!

is just a string, but it can play so many changes, which makes Zhao Di and Yun Mengli both admire.

Xuanyuan Yi pressed the strings with one hand and plucked with the other, because of the difference in contact position time, he could play different rhythms and different lengths of vocal piano sounds, but the difficulty was no.

Yun Mengli continued to cast the Spirit Gathering Gu Spell, replenishing Xuanyuan Yi's mana continuously, while Zhao Di kept those ancient words, and faintly felt that these ancient words were extraordinary!

In the endless yellow sand, the fierce sandstorm had stopped, and the fairy in white disappeared into the yellow sand in a flash, and not long after, he came to a stone gate covered by yellow sand.

Compared with the entrance of Zhao Di and the others breaking the ban and entering the secret realm of Huangsha Cave, it is much deeper, and from this stone gate, most of the people here are the real entrances. ！

The fairy in white waved his sleeves slightly, and a breeze rolled up, blowing away the sand particles covering the stone gate, and on the top of the stone gate, three powerful ancient characters were revealed: "Wujian Valley"!

These three words were left by a Confucian monk. From the meaning of the word, this Confucian cultivator is still proficient in swordsmanship. The girl nodded slightly, dodged into the stone gate, and the next moment, she appeared in a gray valley.

"Confucian monk, proficient in swordsmanship, the immortal aura of the Qiankun sword appeared here, but it is also in the past. Most of the people who refined the Qiankun Sword are the descendants of the Daoists of Kyushu!" The girl muttered to herself, and her divine sense poured out in large quantities, probing the surrounding environment.

"This is a very wide range, not easy to find!" The girl frowned slightly, and after a little groaning, she gently wiped the spirit insect ring on her wrist, and suddenly flew out of it hundreds of martyrdom spiritual lights, turning into colorful spirit butterflies, which are really one of the famous strange insects spirit phoenix butterfly.

The girl separated wisps of divine thoughts, attached to these spirit phoenix butterflies, and then waved her sleeve robe, rolling out a fresh breeze, sending these spirit phoenix butterflies in all directions.

"Go, this secret realm, the scope is no, once you find something, send the divine thoughts back immediately!" the girl commanded softly.

This kind of secret technique is not the same as ordinary divine thoughts.

Thousands of divine thoughts, all independent, far apart, can also be recovered, and grasp what you see and hear in each divine thought, like a dream, it is the rumored dream back**.

And this girl is one of the Mahayana monks of the human race, the Tai Elder of the Cross-border Business Alliance, who dreams of returning to the fairy.
