"This is ..... fire-type spirit seed!!" Shang Fei'er was immediately attracted by this strange spirit seed, as a fire phoenix spirit body, she was very sensitive to the fire spirit seed.

Concubine Shang showed an extremely yearning look: "What a strong fire attribute aura!!Where did you get this spirit seed??"

Gu Chen nodded: "This is a seventh-order rare Fire Sun Ostrich spirit seed, but unfortunately I am an ice spirit body, and this spirit seed is of little use to me at the moment!"

Gu Chen looked sideways at Concubine Shang: "Why don't I send it to you?"

Concubine Shang'er's eyes widened, and she was only half an inch away from Gu Chen at this time: "Seventh Order ??!!! send me!!, Junior Brother Gu Chen, aren't you joking?"

Concubine Shang said quirkily: "You deliberately set up this spirit array to prevent any outsiders from breaking in, and deliberately took out such a high-level spirit seed to tempt me, do you want to take the opportunity to take advantage of this senior sister?!"

Gu Chen laughed out loud: "Take advantage of you, no matter where you are..... you don't seem to have the urge to let me take advantage!"

As he spoke, he glanced meaningfully at Concubine Shang'er.

Concubine Shang's face was scarlet with shame, and then she looked at the female feather man Luo Shui in the cave, which was called a charming and charming person, and compared with her, she was like an undeveloped little girl!

Concubine Shang waved her pink arm hatefully, and said, "Hmph, I'm not rare, I already have the eight-winged immortal firebird spirit seed!"

Although Concubine Shang is the ninth princess of the Snow Dynasty, the resources she has obtained are far less than Shang Weiyang's, and she wants to raise another spirit seed in addition to the immortal firebird spirit, which is a great burden for her, if she can't take care of it, she will take care of one or the other, so that the immortal firebird spirit seed cannot advance!

Gu Chen smiled indifferently, grabbed the little sun with his palm and squeezed it hard, only to hear a bang, the spirit seed suddenly burst open, and a trace of pure fire elemental aura filled the cave mansion violently.

"You ....... you Gu Chen?!, you bad person, even if you don't give it to me, you don't have to destroy the good seventh-order spirit seed!"

Concubine Shang jumped to her feet in a hurry, this Gu Chen was deliberately angry with her.

Gu Chen's face suddenly became solemn: "If you don't destroy it, how can you turn it into the fire evolution source you need!"

"Summoning your firebird!"

Shang Fei'er's cherry mouth suddenly opened the boss: "Evolution source??, you want to give me the seventh-order spirit seed to use as the evolution source?!!

Concubine Shang was already completely stunned by Gu Chen's approach, you must know that if the seventh-order spirit seed is a fire-type spirit seed, it can be sold for at least 700,000 yuan or more if it is put in the treasure house for auction!

And after becoming an evolutionary source, the value shrinks by at least half.

Gu Chen slapped out with a palm, and the pure fire element suddenly flew towards the eight-winged immortal firebird.

The Immortal Firebird swallowed the fire element, and its momentum suddenly skyrocketed.

Concubine Shang stared at the firebird, and the color of the wings of the immortal firebird gradually deepened: "Fifth order, sixth order, seventh order, eighth order!!"

"Eighth-Order Rare Spirit Seed!"

The evolution source generated by the seventh-order rare spirit seed is enough to raise the spirit seed by three or four levels!

Concubine Shang's eyes lit up, and she dragged Gu Chen with both hands: "Little junior brother Gu Chen, how can senior sister thank you?! As long as you say that senior sister can do it, I will definitely promise you!"

Gu Chen raised his eyebrows: "Really??"

Concubine Shang pouted, and said, "Of course, I don't agree to everything, .....but if you can evolve my immortal firebird into a mutant level, I can promise you everything!"

"Do you really promise anything?"

With that, Gu Chen grabbed a sixth-order fire spirit seed again and slapped it over, and the flames on the immortal firebird's body froze, first as flames, then almost as lava, and then as if it were a red-hot rock!

In the end, it turned into a fiery red egg, and the next moment, the fiery red egg peeled off, and a palm-sized firebird flew out!

The firebird's eyes are red and golden, like the core of the sun, which makes people dare not look directly.

"The firebird broke the fire and was reborn, my immortal firebird has evolved into a mutant level!!" Concubine Shang'er's body trembled slightly with excitement, the mutant-level spirit seed in the Snow Dynasty Kingdom was only possessed by the crown prince Shang Weiyang besides his father!

And in the Kunlun General Pavilion, only the disciples and elder-level figures on the Amazing Peak are qualified to have it!

It can be said that the mutant spirit seed is a symbol of strength and status!

The immortal firebird sang loudly, turning into a circular flame mark and flying into the center of her eyebrows, and Concubine Shang'er's temperament seemed to change abruptly.

Concubine Shang secretly operated her vitality, the flame element in the Yuan Pool was extremely thick, and her realm was still through the Yuan Seven Revolutions, but at this moment, she could clearly feel that her strength had increased by at least two percent!

Even Meng Lingqiong was confident enough to defeat her easily.

"Little junior brother Gu Chen, senior sister thinks she is so strong now!!"

Concubine Shang looked at Gu Chen with gentle eyes: "No matter what happens in the future, Senior Sister will definitely cover you, this is Senior Sister's promise to you!"

Gu Chen coughed twice: "Immediately refine the flame aura of the mutant spirit seed, otherwise it will shake your foundation!"

At this time, Concubine Shang'er's eyes were like fire, and she hurriedly sat down and began to breathe!

Gu Chen also sat in the cave and began to cultivate, while Luo Shui sat obediently on the side.

In the Purple Mansion, the main soul is practicing the Haori Golden Light Fist, and after reaching the late form of martial arts, the body shape of the main soul is already comparable to that of an adult man, and a punch is like a storm crashing on the shore, and the Tongyuan Nine Turning Spirit Disciples are also shattered by this punch and have no way to fight back!

Seeing that the main soul law phase was growing so fast, Gu Chen was relieved.

He took a deep breath, and the air flow at his mouth and nose suddenly formed a cyclone and inhaled into his body.

Now Gu Chen can complete the fifty dimensional tidal cycles every ten breaths, and the cumulative airflow of the nine main veins is four hundred and fifty cycles, and a thousand drops of yuan liquid can be extracted in two hours!

This speed has far exceeded the level of the Tongyuan Nine Transition Realm, you must know that even if Ye Wuxin is in the Qianyuan Cave Mansion, which is the highest level of the Asking Heart Cliff, the vitality is several times richer than here, and two hours are only to extract a hundred drops of Yuan liquid!!

Tongyuan seven turns, all the main veins are cultivated to the veins of iron skin!

Gu Chen's vitality was running, and suddenly starting from the first main vein, the nine main veins began to emit the sound of rushing water one by one.

The speed of the fifty-dimensional tide cycle every ten breaths, if it is placed on an ordinary spirit disciple, the main vein can not only be rushed into an iron shape, but can even reach the level of the golden tendon vein.

However, the strength of Gu Chen's main vein is different from ordinary people, even Ye Wuxin is probably less than one-tenth of his, so the Yuan Tide circulation strength required by Gu Chen's desire to rush into an iron vein is not very comparable.

This is also the most distressing place for Gu Chen, the same realm, he needs to spend ten times or even a hundred times more effort than ordinary people to achieve!

Inside the cave, thin Yuan Qi gathered from all directions, and the speed of extracting Yuan Liquid was also accelerating.

Sixty breaths! The Yuan tide continued to accumulate, and the sound flowing in the main vein became more turbulent.

Gu Chen shook his head, seventy breaths, the Yuan tide is like the waves of the sea, one after another, it still doesn't work!

Eighty breaths!

Ninety breaths! The rocky main vein gradually revealed its blackness.

One hundred breaths!

At this time, in Gu Chen's body, the sound of roaring continued to echo, as if nine great rivers were rushing non-stop.

The black main vein glowed with a metallic matte, and the roaring sound disappeared abruptly, and the Yuan current became unhindered, because the surface of the main vein at this time had turned into black metal!

Call!

"Tongyuan Seven Turns Iron Vein!!It's done!!"
