As soon as the words fell, the little girl's body suddenly stumbled and almost fell. 【】

Li Yunfei immediately stretched out his hand to support Jiu Jiu, and asked with concern, "How is it?

Speaking of which, although Jiu Jiu is a genius of all magic systems, it is still a black iron level combat power, even if it is a crazy absorption of the surrounding magic elements after devouring the Storm Spirit Flower, it has been greatly improved in a short period of time, and the explosive attack just now is really beyond her ability to bear, and it is normal to have some physical discomfort.

Jiu Jiu casually took out a bottle of potion from the storage bag, opened it and drank it, this potion emitted a faint purple glow, which looked extremely unusual. Li Yunfei just sniffed it, and immediately felt physically and mentally happy, and his whole body was comfortable.

"This is the White Bone Styx water that the teacher gave me, which is of great benefit to stabilizing mental power, and it is out of the way now. Chirp said with a smile.

Hearing this, Li Yunfei relieved himself. Speaking of which, the teacher of Jiu, Hades Meria, is really different, and this potion that restores and stabilizes mental power also uses such an eerie name, but it is really effective.

"This Storm Spirit Flower deserves to be called a miracle medicine, and my magic power has now completely broken through the peak of the Black Iron level and reached the Silver level. Chirp's spiritual power poured out like flowing water, surrounding the surrounding woods, caressing everything around him. Compared to before, her mental power has become smoother and broader.

Li Yunfei himself had also come into contact with many silver-level mages, so he could naturally clearly feel that Jiu Jiu's spiritual power had completely reached the silver level!

rubbed the little girl's head lovingly, and Li Yunfei's face also showed a happy expression.

Then Li Yunfei lightly punched his heart, instantly transformed into a giant form, held a huge Baipi knife like the ground, and began to mine this open-air Wood Demon Crystal vein.

The ground of the surrounding forest, which is hundreds of meters in radius, is completely composed of pieces of incomparably pure Wood Demon Crystals, and it can be said that this Wood Demon Crystal vein is the essence of the entire giant wood forest.

Every time Li Yunfei slashed down, a huge wood magic crystal was split by his huge force, and the green light flickered into the air, and then the white light flashed, and he was included in the space ring.

Beside him, Chirp waved her hands again and again, and thick python-like vines poked out from the towering giant trees around her, constantly rolling up pieces of wood magic crystals and putting them into a spatial bracelet on her wrist. The bracelet was engraved with a circle of skulls, apparently gifted by Meria, the king of Hades.

I saw that green light and white light flashed alternately, and with a huge roar, the entire Wood Demon Crystal vein quickly disappeared into the storage space of the two of them.

A giant between the pinnacle of black iron and the silver level, a full-line silver mage, the efficiency of the two of them in mining can only be described as amazing.

Normally, how could such a Wood Demon Crystal vein be able to supply several Black Iron Generals for more than ten years, but it only took less than an hour for the two of them to completely mine it, and the entire vein had completely turned into a bare pit, and there was not even a bit of slag left in it.

Just after the two of them put away the last bit of the Wood Demon Crystal, the thickest towering giant tree in the center of the vein suddenly let out a "squeak" scream, and then began to crack a huge gap in the middle, extending from the root to the treetops hundreds of meters high, and then fell down like a flower in all directions.

The fact that this giant tree was able to grow into such an almost terrifying tall form was completely due to the fact that it was located in the center of this Wood Demon Crystal Vein, and it could be supported by a huge amount of wood elementals. Now the entire Wood Demon Crystal Vein disappeared in an instant, and without the support of the almost substantial wood element, the inside of this giant tree was immediately unable to support its own weight, and it actually collapsed.

Seeing this scene, Li Yunfei couldn't help but have a hint of enlightenment. Sometimes, something that seems to be powerful and terrifying, once it loses its own support, it can't even continue to survive like those weak, but will be swallowed by its own strength.

The giant trees that were divided into several pieces of "creaky ......" completely collapsed, rolling up puffs of dust, and even completely rotted in many places, leaving only a stump of three or four meters thick and more than ten meters high.

The dust cleared, and a green glow spread out, along with a charming fragrance.

Li Yunfei couldn't help but let out a "huh", looked down, and saw an emerald green gem the size of a human head lying in the center of the stake, and the dark green shadows in it were connected into patches, looking as if it was a miniature forest with life.

After seeing the miracle of the fire demon marrow, Li Yunfei naturally understood what this thing was.

If this Wood Demon Crystal Vein is the essence of the entire Giant Wood Forest, then this thing is the essence of the entire Wood Demon Crystal Vein, the Wood Demon Marrow!

Li Yunfei's face was overjoyed, and he immediately stepped forward and put this wood magic essence into the space ring.

Then he grabbed the remaining ten meters of stumps, mobilized the strength of his whole body, and pulled the remaining piece of wood up.

This piece of wood was extremely heavy, more than twice the weight of the Hundred Pier Knife, and it was far harder than the iron wood and steel wood, much harder than the handle of his Hundred Pier Knife.

A towering giant tree hundreds of meters high, after completely decaying, only such a little essence remains, which naturally shows how precious it is.

Although the Baipi knife is extremely sharp, it has made great contributions to Li Yunfei's side for a long time, but with the enhancement of Li Yunfei's own strength, the Baipi knife has sometimes made him feel that it is faintly too light, and new materials are needed to build it.

This hard wood is just what he wants!

Thinking of this, Li Yunfei casually threw the Baipi knife and this piece of wood into the space ring, and said to Lao Yan in the sea of knowledge: "Lao Yan, it's up to you, it's time to work after eating and drinking for so long." ”

Lao Yan immediately poked a head out of his left arm, and said with an arrogant face: "What did Uncle tell you? As long as you have enough materials, Uncle will definitely be able to give you a peerless blade! Tell you, even other gods once asked me to help forge weapons, but now that Uncle has only recovered less than one-ten-thousandth of his strength, it is still no problem to help you sharpen your knife, so you just wait and see!"

As soon as the words fell, he had already drilled back again, and at the same time probed a trace of thought into Li Yunfei's space ring.

Li Yunfei nodded and said no more. Lao Yan had said before that there was also a forging skill, but he had not been able to carry it out because he didn't have enough suitable materials, and he really wanted to see what the forged Baipi Sword would look like.

After doing all this, Li Yunfei regained his human form, left the forest with a twinkling of his eyes, and walked into the distance. There are so many things in this steel soul half-plane that the little chirping nose hasn't been fully used.

......

The original Wood Demon Crystal vein was now only a bare pit,

Only the surrounding wood elements that have not completely dispersed indicate that something once existed here.

After Li Yunfei and Jiu Jiu left for almost half a day, there was a "rustling" of footsteps in the surrounding forest, and at the same time, black figures were rapidly approaching from a distance.

Dozens of figures reached the edge of the pit almost at the same time.

"Ahh

"This ...... How is this possible!Ore vein, my ore vein!My Wood Demon Crystal vein!" This person was dressed in a silver temple armor, and there were patches of dirty blood all over his body, looking embarrassed, it was the Holy Imperial City warrior Gagaru who had escaped not long ago
