"This dragon spirit elixir is a very rare treasure, and only the dragon clan that has reached the Sanqing Realm can produce it. However, the storage conditions of this dragon spirit elixir are a bit harsh, and it can only be stored with a dragon bone, and using utensils of other materials will make it inactive and become a waste product. Bi Fangniao said again.

"That's easy." Xuanyuan wielded the Seven-Star Dragon Yuan Sword, cut off a keel next to him, divided five by two in three strokes, and made dozens of bone bottles with a volume of about one liter from this keel. I have to say that only the sharpness of the Seven-Star Dragon Yuan Sword, combined with the spatial attributes of Shangxuanyuan, can carve the keel so easily.

After making the bone bottle, Xuanyuan once again used the spatial spiritual power, carefully sucked the dragon spirit elixir out of the keel, and filled the bone bottle one by one. These dragon spirit elixirs were filled with more than a dozen bone bottles. Although a dozen liters of liquid seemed nothing compared to this huge skeleton, for Xuanyuan and the others, it was already a lot of harvest.

Continuing to explore, Xuanyuan still surveyed each keel one by one as before, but until the end, he didn't find anything special. When they were done, they turned back and returned to the dragon's head.

At this time, the Silver Wing Demon was already meditating and recuperating. In addition to the limbs and wings, the structure of the body of the Silverwing Demon is quite similar to that of humans, so when they rest their state or meditate, they also meditate cross-legged, which is somewhat similar to humans.

"Lord Bi Fang, my state has recovered to the best, you see, can you help me complete the second evolution?" Seeing the four of them return, the Silver Wing Demon hurriedly got up and greeted everyone. He was very interested in not asking about everyone's gains, perhaps because he considered that only by not asking, would he not be greedy.

"Okay." A red light flashed in front of Wang Sanniu's body, and Bi Fangniao's figure appeared again, and after hovering in the air a few times, he came to the Silver Wing Demon and turned into a human form.

Seeing it transform into a human image, everyone present, except for the Silver Wing Demon, was stunned - Bi Fangniao's human image turned out to be a woman!

Wearing a long red skirt with a long skirt and a bright red shawl, although it seems simple, it is very eye-catching. The arms that are as white as mutton fat and the jade feet that are slightly exposed from under the skirt can be called the face of the calamity, coupled with the cold and arrogant expression that does not eat the fireworks of the world, this is the human appearance of Bi Fang Bird.

"Female ...... Woman...... Female? Looking at the image of Bi Fangniao, Wang Sanniu's jaw was about to fall off. Bi Fangniao, who has been with him for nearly 20 years, is actually a daughter! In that case, when she was bathing and sleeping, wasn't her body seen all over by her? ……

Wang Sanniu was surprised, and everyone was naturally surprised. If you don't say anything else, just talking about the voice, it's completely incorrect. Bi Fangniao's previous voice, although it was not rich and loud, was also the type of baritone, but how did he get here and turn into a woman?

"Could it be...... Pseudo-mother, right? Xin'er looked at Bi Fangniao's appearance and whispered to Xuanyuan. However, Xuanyuan doesn't know the gender of Bi Fangniao, and his understanding of Bi Fangniao comes from ancient books, and his understanding of Bi Fang is not as much as Wang Sanniu.

"Little girl, it's not a polite thing to slander this seat behind your back......" Bi Fangniao seemed to hear Xin'er's words and said to Xin'er.

With this opening, the voice changed, no longer the male voice before, but a female voice. Although her voice is slightly lower than that of little girls like Xin'er and Zimeng, it is definitely beautiful, and she has a high-minded, queen-like temperament. At this moment, everyone didn't understand what Bi Fang's gender was all about.

"Sorry......" Seeing that the other party was aware of her words, Xin'er bowed slightly and apologized.

"Don't be surprised, I'm deliberately disguising my voice when I talked to you before, and the voice I'm talking to now is the original voice of Izuku." Bi Fangniao explained, and at the same time, he also came to the Silver Wing Demon.

"Your Excellency......" When the Silverwing Demon saw Bi Fang Bird coming, he immediately turned into one knee and bowed his head towards Bi Fang Bird's spirit body.

"Get up, spread your wings, pierce the tips into the keel, and I'll teach you how to make the most of this dragon skeleton to achieve the best results in your secondary evolution." Bi Fangniao instructed.

The Silver Wing Demon was very obedient and made corresponding actions according to the requirements, and Bi Fangniao directed his actions according to the agreement.

"Then there's nothing to do with us now, Sanniu, you first refine all the beast crystals harvested today." Seeing that the Silver Wing Demon and Bi Fangniao couldn't finish it for a while, Xuanyuan also signaled to Wang Sanniu.

"Is it all refining?" Wang Sanniu asked.

"Well, just refine it, no need to save." Regulus nodded.

When Wang Sanniu heard this, he summoned his own alchemy tripod and threw the seven fire attribute beast crystals harvested today into the pill tripod in turn. With the refinement of his ninth-level fire attributes, these beast crystals that had reached the god's desperate realm were still like ordinary medicinal materials, which were refined by Wang Sanniu and became piles of spiritual power powder. Subsequently, Wang Sanniu continued to refine, and the violent aura in the body of the demonic beast in those spiritual power powders was also gradually refined, leaving only the purest part of spiritual power.

After about a stick of incense, seeing that these spiritual power powders were pure enough, Wang Sanniu took out a few more medicinal herbs used to balance the medicinal power and added them to the medicine tripod. After a period of refining and fusion, a crimson elixir was formed.

"Although I don't know if anyone has refined it like this before, I decided to give it a name myself, called Fire Spirit Pill. But...... Are you sure this thing works? Won't you let me explode and die? Feeling the powerful spiritual power of the elixir he refined, Wang Sanniu was also a little uncertain. After all, this is the purifying spiritual power of the seven Divine Desperate Realm Demonic Beast Crystals, and he is only a Spiritual Desperate Realm!

"If it was before, I might have let you refine one by one, but now, it's different, we have this thing, you don't have to worry about not being able to digest these spiritual powers." Xuanyuan took out a bone bottle and smiled.

"You'd better not trick me...... Wang Sanniu said suspiciously, but in fact he was more anxious than anyone else, took the Dragon Spirit Elixir from Xuanyuan's hand, poured a big mouthful, and then directly swallowed the red elixir into his stomach.

The dragon spirit elixir enters the throat, and Wang Sanniu's first feeling is cool!

The silky slurry slid down his throat into his abdomen, reached his abdomen, and was directly absorbed into his body, and then he could clearly feel that the spiritual power of his body was running three points faster than before. Although the spiritual power is still those spiritual powers, it is much smoother to mobilize than before.

After that, it's the spiritual power pill just now!
