The endless plains are crisscrossed by several mountain ranges, crisscrossed like a giant dragon crawling.

These mountains are very strange, shining in the sunlight with speckled dazzling light, as if they are covered with a layer of reflective scales, and when you get closer, you realize that they are actually transparent 'flowers'.

The strange thing is that these 'flowers' are crystal flowers composed of amethyst, but they bloom like real flowers, and their shapes are vivid!

No one knows why such strange crystal flowers appear here.

Thousands of 'flowers' competed for beauty, Qin Sang's figure appeared at the foot of the mountain, looking at this beautiful scene, he couldn't help but secretly admire.

He discerned the direction, and Edgeworth flew to the side of a mountain, then took out the Shadow Guard's token, and after sensing it, slowly walked to a crystal flower.

The purple crystals sparkle in the sunlight and don't look much different from other crystal flowers.

Who would have thought that there was a secret realm hidden in this inconspicuous crystal flower. To be precise, the Crystal Flower is the entrance to the Celestial Crystal Secret Realm.

It has the charm of a flower and a world.

As soon as Qin Sang stood still in front of the crystal flower, after a breath, a strange fluctuation suddenly swayed in the stamens of the flower, and then Qin Sang felt a tingling pain in the center of his eyebrows, as if he was locked by a sharp sword.

Obviously, the people in the secret realm were sure that Qin Sang was coming to the secret realm and was issuing a warning.

"Hanging skull Guan Yingwei, Shaohuashan disciple, Qin Sang! Meet Senior Brother Fujinan! In addition, entrusted by Senior Brother Yuyangzi, I brought a letter and asked Senior Brother Fujinan to open it in person. ”

Qin Sang explained the origin loudly, and held up a jade slip with both hands, which contained the letter left by Yu Yangzi.

I saw the stamen of the flower open suddenly, and then the fluctuation turned into a deep whirlpool, and a suction force came out of it, sucking the jade slip into the secret realm, and then there was a faint sound of talking.

"Senior, please wait a minute......"

Qin Sang stood with his hands tied and waited quietly.

A moment later, the light in front of Qin Sang's eyes dimmed, and a strong man in golden armor appeared in front of him.

"Senior Brother Qin," the strong man in golden armor arched his hand to Qin Sang, and said in a kind tone, "Down there is Tengnan, who is responsible for guarding the secret realm, if there is any neglect, please forgive Senior Brother Qin." ”

Qin Sang secretly looked at this Senior Brother Tengnan, he might have to be in the same secret realm with him for decades, and if he met a perverse person, it would also be a big trouble.

Wearing gold armor, Fujinan looks extremely powerful and imposing, but his face is quite kind, and he should not be a difficult person to get along with.

Qin Sang returned the salute meticulously, "Senior Brother Teng is responsible, and he should be cautious." It was Qin Sang who took the liberty and came to disturb him, hoping that he did not disturb Senior Brother Teng. ”

Hearing this, Fuji Nan smiled, looked Qin Sang up and down, and said, "Senior Brother Yuyangzi believes that I have already read it, Senior Brother Qin, please come with me...... The Heavenly Crystal Secret Realm is not as rich as other secret realms, but it is still no problem to set aside a cave. ”

As he spoke, Qin Sang followed Fujinan into the whirlpool, and he felt that his eyes flickered, and the scenery in front of him changed greatly.

The blue sky and white clouds, the air is fresh, and the aura is rich and abnormal.

From a barren Gu Immortal Battlefield to the Heavenly Crystal Secret Realm, it was as if he had suddenly entered a fairyland.

Surrounded by several green hills, planted with a spirit tree called Huang Qiao.

The grass in the plain is fragrant, a big river meanders through, I don't know what to do, and there are large and small medicine gardens on both sides of the big river, and many elixirs are planted in them.

The familiar scene made Qin Sang a little in a trance, and suddenly remembered the time of Yuanzhaomen.

In the depths of the secret realm, a space blocked by a dense fog, Qin Sang knew that it was the biggest secret in the secret realm, it could be the Ancient Cultivation Relic Mansion, or it could be the Ancient Medicine Garden, in short, it was best not to peep.

After entering the secret realm, Qin Sang saw two more guards wearing golden armor, both of whom were in the Qi refining period, and after Teng Nan's introduction, he learned that one was a disciple of Shangyuan Qingjing Palace, and the other was a disciple of Taiyi Danzong, and they were the ones who spoke.

The guards in the secret realm are all under the command of Fujinan, and they take turns to be on guard.

"Some of the others go out to practice, some are in retreat and penance, Senior Brother Qin will live in the secret realm for a long time, and then introduce to Senior Brother Qin in the future," Teng Nan introduced the secret realm to Qin Sang one by one, and finally pointed to the prohibition above the secret realm and said, "The secret realm is not stable, especially when the celestial phenomena come, if Senior Brother Qin can lend a hand, it will be much easier to be a brother." ”

Qin Sang Zhengse said: "Senior Brother Teng, don't worry, when you need my help, even if you tell me, I will never ignore it." ”

Fuji Nan nodded with satisfaction, and led Qin Sang to fly to a mountain in the depths of the secret realm, and saw that more than a dozen caves had been opened up on the cliff, all of which were forbidden and blocked.

Fuji Nan pointed to one of the caves and said, "This is the strongest spiritual energy in the entire secret realm, which is enough to meet the cultivation needs of the monks in the foundation building period. This is my cave mansion, the others are all ownerless things for the time being, Senior Brother Qin can pick one at random, and use the Shadow Guard Order to open and close the cave mansion. There is also this, it is a map near the Heavenly Crystal Secret Realm, and some of the places where cloud beasts live are marked, Senior Brother Qin should pay attention to avoiding these places when he goes out to practice. ”

Taking the jade slip handed over by Teng Nan, Qin Sang probed his divine sense into it, and found that the map inside was much more detailed than the one given to him by Yu Yangzi, it should be the accumulation of the guards of the Heavenly Crystal Secret Realm for so many years, which was very precious.

Putting away the jade slip, Qin Sang immediately took out the shadow guard order, saying that he would give Fuji Nan half of the good deeds and lease the cave mansion.

The so-called cave is actually just a cave, the walls are extremely rough, and you can even see the traces of sword cutting, and there is only a stone bed in the cave, and there is nothing else.

It looks like a savage dwelling, but it is a very rare place to stay in the Gu Immortal Battlefield.

Qin Sang didn't care about the furnishings of the cave mansion, he glanced at it casually and ignored it, closed his eyes and ran the exercises, stopped after a week, and nodded secretly.

It is far inferior to his Lingquan Cave Mansion, but it is also enough to support cultivation.

"I can finally cultivate with peace of mind!"

Qin Sang sat on the stone bed, let out a long breath, and after thinking about it, he took out Yin Xingge's spirit beast bag.

The corpse searched for the spirit beast bag and a few scattered magic weapons in the mine, but the most precious mustard seed bag was not found, and it may have fallen into the cracks in the ground.

There are a lot of bottles and cans in the spirit beast bag, and there are more than a dozen kinds of demon insects in it.

There is also a jade slip in the spirit beast bag, which is the experience of the Medicine King Sect in cultivating demon insects, Qin Sang studied it carefully, and found that these insects are not of great use, most of them are used to assist in cultivating elixir.

Thinking of the identity of Yin Xingge's Medicine King Sect's disciple, Qin Sang was relieved.

But there is only a fiery red centipede, which is not introduced in the jade slip, Qin Sang intuitively felt that this insect was extraordinary, and when he was in Changyangfang City, he found a chamber of commerce attached to the Imperial Spirit Sect, and spent a lot of money to buy a demon insect atlas in the store he opened, only to know that this insect is a rare strange insect, called the fire jade centipede!
