"Mentor Rorty, wait a little longer, the sun will still set in half a moment......"

"What Senior Sister Huo said is very true, please ask Tutor Rorty to stay for a while!"

Rorty's voice fell, and Huo Ruiqi and Zhu Gui, who were standing behind him, took a step forward and asked, they had never seen Xu Hong's body, and the two did not believe that Xu Hong had fallen, not to mention, the demon beast eggs in the nest of the "Golden Pupil Devouring Stone Rat" were obviously traces of human movement.

"Look, Xu Hong is out!"

Suddenly, Rorty, who was about to speak, stared at each other, and at the same time, Zhu Gui's loud shout sounded in his ears, but he saw a figure flashing in the distance, and it was Xu Hong who had returned from the cave.

......

"Guangling Lingcheng" the largest trading club - Wanbao Building.

Xu Hong, who had returned from the "Wuling Mine Cave", had a night's rest, and the next morning, he came directly to the "Wanbao Building", and if he wanted to complete the collection of all the materials of the "First-Order Evolution Liquid", Xu Hong needed to sell some items.

And the fur, flesh and blood of the "Stone Devouring Rat", as well as dozens of "low-level demon cores", Xu Hong can't use them, and they can be exchanged for spirit stones for the purchase of high-level spiritual materials, for example, the "high-level demon core" with five element attributes, the energy in it is enough to make Xu Hong swallow the "first-order evolution liquid" and successfully advance.

"Well, to refine the 'First-Order Evolution Liquid', you still need to rent the Academy's 'Earth Fire Secret Room'!"

Half an hour later, Xu Hong, who walked out of the "Wanbao Building", showed a hint of relief on his face, although the spirit stones in the "storage bag" were greatly reduced again, and there were only more than fifty lower-grade spirit stones left.

However, the materials required for the "first-order evolution liquid" are finally all in place, and for the experienced Xu Hong, the completion of the procurement of materials indicates that the "first-order evolution liquid" is about to be baked.

"This is the 'Jade Talisman Key' of the Thirteenth "Earth Fire Secret Room", and if it is more than two hours, you need to pay the spirit stone separately!"

The control of "Danxia Academy" is extremely relaxed, only every three days, you can go back and forth to the college, and you can usually dive and cultivate by yourself.

Immediately, Xu Hong, who took over the "jade talisman key", answered, no longer stayed, passed the stairs in front of guò, and went straight down, as a secret room for hooking up the "earth fire", it was built under the ground more than ten zhang deep, and there was a "earth fire spirit flame" pulled by a strong man in the secret room.

"Hmph, just the cultivation of the second layer of Qi training, and the vain use of the "Earth Fire Spirit Flame", I really don't know the severity, such a waste of good spirit stones!"

When Xu Hong was far away, the middle-aged monk of the "Sixth Layer of Qi Training" who put away the two lower-grade spirit stones let out a cold snort with disdain and regret, and whispered softly.

As a middle-aged monk who is just a "lower grade spiritual root", without the supply of resources from his family and forces, it is extremely difficult to break through the "late stage of qi training".

"Quack ......"

After a burst of sound of the stone door turning, Xu Hong, who had entered the thirteenth "Earth Fire Secret Room", sensed slightly, and a smile appeared on his face, as a "Earth Fire Spiritual Flame" that can be compared with the "Innate True Fire" of the "Foundation Building" monk, the "Earth Fire Spiritual Flame" with spiritual energy, has been inextinguishable for a long time, so that the concentration of spiritual energy in the entire secret room of the three zhang square circle has increased by one layer.

"With this aura environment, it's not in vain to waste two spirit stones!"

Xu Hong, who took a deep breath, whispered, and immediately did not delay, after closing the "Stone Door of the Secret Room" engraved with the forbidden talisman, he took a few steps forward, and sat cross-legged directly in front of a stone pillar with a white "spiritual flame" at the end.

Then, Xu Hong's probe hand gently stroked his waist, and in the next moment, a "Beginner Dan Furnace" appeared out of thin air and was placed above the stone pillar by Xu Hong.

"Buzz ......"

The next moment, Xu Hong's spiritual power rolled, and where his mind moved, a wisp of red white spiritual flame suddenly rose and submerged into the base of the "Beginner Dan Furnace", and with a soft sound, the base of the calm "Dan Furnace" rose up with a red white flame that slightly dispersed the spiritual energy.

"Whoa......

The lid was lightly opened, and a bottle of "Spirit Eye Liquid" turned into a silver thread and injected into the "Elementary Dan Furnace", compared to the clear spring purification water used to refine the ordinary "Qi Condensing Pill Pill", the "Spirit Eye Liquid" was much more valuable.

The aura stretches and the red flame is picturesque.

With the fierce rise of the flame at the base, several spiritual grasses thrown into the "Dan Furnace" were slowly melted at a speed visible to the naked eye, like ice and snow under the sun.

"Goo!"

After a short time, the essence of the spirit grass that was refined into liquid, rolling and churning, one by one with the spirit grass, under the control of Xu Hong's divine thoughts, one by one into the "primary Dan furnace", and then, under the impregnation of the essence of the spirit grass, it quickly softened and fused.

"Rongdan ......"

After the essence of the herb liquid in the "Elementary Dan Furnace" was completely fused, Xu Hong's face became more and more solemn, his wrist flipped, and the five inner Dan demon cores of the "Advanced Demon Beast" were swept into the Danding by Xu Hong with spiritual power.

Immediately, the divine power of the "Five Layers of Qi Training" realm was all dispatched, regulating the furnace fire, differentiating the turbulent and surging spiritual liquid, and the five elements of the inner Dan demon core, although they are mutually beneficial, but they are also mutually restrained, and there is a slight difference, and the five elements of the spiritual energy decomposed by the inner Dan demon power will be in danger of colliding with the blaster.

Rao is Xu Hong was quite confident, but he didn't dare to relax in the slightest, after all, the success of the refining of the "First-Order Evolution Liquid" was directly related to whether Xu Hong's spiritual root qualifications could be improved.

"Condense!"

After the kung fu of the two teas, Xu Hong, who looked solemn, suddenly let out a clear drink, and then, the five inner Dan demon cores that had successfully melted into liquid stirred with each other, forming a trace of fluctuation, and then, pushing the various spiritual materials and treasures in the Danding to slowly rotate at strange and different frequencies.

One lap!

Two laps!

......

One hundred and eight laps!

"Liquid!"

Until the spiritual liquid in the Danding completed one hundred and eight circles of rotation of different frequencies, Xu Hong's solemn face began to show a hint of joy, and then, after a low voice, the spiritual power vibrate, and the divine thoughts were everywhere, and a purple ribbon of water rose into the air, out of the "Elementary Dan Furnace", and fell towards the jade crystal bottle that Xu Hong took out.

"Po ......"

After two or three breaths, the calm "Dan Furnace" sounded a soft sound, and the liquid in the Ding was completely empty, and at the same time, Xu Hong, who was infusing spiritual power into the base of the "Dan Furnace", also closed his hand, and could not hide his joy to look at the liquid in the jade crystal bottle in his hand, overflowing with purple light.

"The first-order evolution liquid has finally been completed!"

When he was in the federal world, Xu Hong, as an intermediate scientific researcher, even the more complex high-end yuan liquid had been furnaced, and this time he picked it up, although the equipment was different, but it was also completed smoothly.

However, although it is quite smooth, as the first refining of the "evolution liquid" in the world of Xianxia, Xu Hong still can't hide the excitement in his heart, with such a "gene liquid" means, Xu Hong believes that it is expected to rise in this world and become a strong man who controls the general trend!
