After Su Wu finished speaking, he saw Xiaoqing pondering motionlessly, and Su Wu didn't bother it, waiting quietly beside him.

"Master, you said that you can't refine this true dragon blood, could it be because this may not be the blood of the nine-clawed golden dragon we imagined?"

When Su Wu heard this, he obviously froze for a moment, he didn't think that it would be this reason, and couldn't help muttering: "Isn't it the Nine-Clawed Golden Dragon?

Xiao Qing continued: "Master, have you ever heard of the Ancient Thunder Dragon, the blood of the Ancient Thunder Dragon, which can also be called the true dragon blood, but the blood of the Ancient Thunder Dragon also contains the power of thunder and lightning, and the Thunder Dragon Treasure Blood is much more precious than the True Dragon Blood." ”。

"Have you ever been on the Thunder Dragon, of course you've heard of it, do you mean to say that these are the Thunder Dragon's Treasure Blood, so I can't refine it?" Su Wu's eyes flashed with a thick look of surprise, and he said incredulously.

Ancient Thunder Dragon, of course Su Wu knew. The Elder Thunder Dragon can be said to be the most precious and rarest race of all dragons. They are naturally stronger than other dragons, because in addition to possessing the supernatural powers of ordinary dragons, they also have terrifying thunder powers.

There is also a legend that if the blood of the ancient thunder dragon can be refined, then the person who refines it will automatically inherit it and have the ability to release thunder and lightning.

"It should be so, master, just now when I was quenching my body in Guding, I faintly felt that there was thunder and lightning power in those bloods, but you have extracted the essence, and in the remaining blood, the energy of thunder and lightning power is very weak, so I was not sure at first. Xiaoqing explained.

"Then if it's really an ancient thunder dragon, how can I refine these five drops of thunder dragon blood?" Su Wu then asked.

"Master, Xiaoqing has heard that if you want to refine the blood of the Ancient Thunder Dragon, you must find the help of herbs containing the power of thunder and lightning before you can easily refine it. Xiaoqing thought for a while and said.

"The herb of the power of thunder and lightning? You mean the Ice Spirit Thunder Vine Grass, this kind of herb, I know, but it is very rare, and I am afraid it is not easy to obtain. When Su Wu heard Xiaoqing's words, he frowned and said.

"Master, it's definitely hard to find it if you look for it blindly, but there is Xiaoqing, it's different, you see. After Xiaoqing finished speaking, he suddenly released the energy on his body, only to see that the top of Xiaoqing's head suddenly lit up, and there was a faint arc shining.

Su Wu's eyes were full of surprise, Xiao Qing actually released lightning? It had never shown this ability before?

"Xiaoqing, did you learn this lightning when you just quenched your body in Dingnei?" Su Wu said incredulously.

"Yes, master, it's just that the quenching time is not long, the power of thunder and lightning is not very great, once I can release more energy, thunder and lightning will be inducted, and we will definitely find the Ice Spirit Thunder Vine Grass." Xiaoqing continued.

Su Wu waved his hand and said indifferently: "Although you are refining, it's okay, how long will it take you?" I'll be waiting for you here." ”

"That's not necessary, I can directly refine this Gu Ding, put it into my body, and quench my body at any time, I have a feeling that this Gu Ding should also be a great treasure. Xiaoqing said disapprerovingly.

Su Wu couldn't help but roll his eyes, and said, "Xiaoqing, what are you kidding, you are a demon beast, and you have not yet turned into a human, how can you refine this Gu Ding." ”

Su Wu obviously didn't believe Xiaoqing's words.

Xiao Qing snorted coldly, ignored Su Wu, and went directly into the Gu Ding.

"Buzz!"

Xiao Qingpan was lying in the center of the ancient ding, the energy on his body was released with all his strength, and the thunder and lightning light immediately shone on his head, and the arcs continued to fly in all directions, and those arcs shot into the iron wall and disappeared quickly.

Su Wu leaped up and stood on top of Gu Ding, glanced at him a few times, and muttered even more suspiciously: "Hey, that's not right...... How could there be a white light on the top of Xiaoqing's head? Could it be that it used its aura to refine?"

How could there be white light in the power of ordinary thunder and lightning? There was only one explanation, Xiao Qing also released the aura, and it wanted to use the aura and the power of thunder and lightning to refine this Gu Ding together.

Su Wu held his breath and stood on the ding, quietly watching Xiao Qing below continuously release the power of thunder and lightning and true qi, and the combination of the two powers actually carried some divine aura.

One hour, two hours, three hours!

Gu Ding didn't react, Su Wu's face also sank, it seems that Xiao Qing can't refine this divine ding.

Xiaoqing seemed to be a little tired, stopped and looked at Su Wu, "Did you bring too much braised beef, eat something to replenish?"

Su Wu couldn't help but roll his eyes again, but he still took out some braised beef and threw it into Xiaoqing's mouth.

After gobbling up some braised beef, Xiao Qing rested for a while and continued to release thunder and lightning and true qi.

Su Wu knew that Xiao Qing would not refine soon after a while, so he simply sat on the tripod and closed his eyes to cultivate.

Half a day, one day, two days!

Three days later, Su Wu opened his eyes again and saw that Xiaoqing was still releasing energy tirelessly.

I can't help but worry about Xiaoqing, such a non-stop release should be very draining on the mind.

In the midst of Su Wu's thoughts, the Gu Ding suddenly shone brightly, violently shaking, and Su Wu was already sitting on the Ding, and suddenly rolled down.

At first, he thought there was an enemy attacking, but he didn't find any enemies.

"Whew!"

Xiaoqing suddenly flew out of Gu Ding, and Gu Ding suddenly flew up, becoming smaller sharply, and finally turned into a phantom and disappeared into Xiao Qing's eyebrows.

"Haha!"

Xiaoqing grinned and shouted at Su Wu, his face full of joy and invitation, like a child who had done good deeds and was waiting for praise from his elders.

"Xiaoqing, has the Gu Ding been refined by you?" asked Su Wu with a laugh.

"Of course, there is nothing that I Xiaoqing can't do. Xiaoqing said without modesty.

Su Wu was obviously in a good mood, and he didn't hit Xiaoqing this time.

In addition to getting five drops of pure ancient thunder dragon blood, Xiaoqing's combat effectiveness has also made a great leap, not only has he learned the thunder and lightning skills, but his body has also been tempered stronger.

"Xiaoqing, you still need to continue to quench your body and practice thunder and lightning skills, should we return to the Li family, and by the way, let the Li family help inquire where to find the Silkworm Razer Grass?" Su Wu proposed.

"Master, listen to you, just find me a quiet place suitable for cultivation. Xiaoqing said indifferently.

"Then it's decided. After Su Wu finished speaking, he adjusted it and left the ancient ruins with Xiaoqing.

When Su Wu walked out of the valley, he only heard the sound of "boom, boom" from behind.
