Someone's coming!

Chu Qingyun's heart tightened, and without wasting any more time, two or three swords split the head of the thundercloud lion, and three ten-star vines probed in, and quickly grabbed a fist-sized demon core. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Fortunately, the new sword is sharp enough, otherwise, if it is replaced by the previous black iron long sword, it may not be able to cut the hardest skull of the thundercloud lion in a short time.

The demon core of the thundercloud lion is light purple, and tiny thunderbolts emerge from it from time to time, looking like a beautiful work of art.

However, Chu Qingyun didn't have time to appreciate it now, and after putting away the demon core, he used his stealth soul technique and quickly left here.

Although the huge body of the demon beast is also very valuable, it is a very strange thing for the corpse of a demon beast the size of a house to disappear out of thin air.

Chu Qingyun would rather not have the benefits on the Yuan Stone, and he didn't want to expose the fact that he had a storage ring.

After all, it was something that even the martial arts powerhouses would be blushing at.

Not long after Chu Qingyun left, a group of people cautiously came to the body of the thundercloud lion.

Led by a middle-aged man in blue, his left and right sides, slightly behind, followed by Cao Meng and Cao Jingbin.

This person is the head of the Cao family in Yancheng, Cao Meng's father, Cao Jingbin's eldest brother, Cao Jingwen.

At this time, Cao Jingwen's face was a little ugly.

In the previous battle between Chu Qingyun and Lei Yun Lion, the disturbance that caused it alarmed the Cao family warriors who were surrounded by them.

They hurried and hurried, but they didn't expect it to be a step too late, the Thundercloud Lion, and was killed by others in advance!

"Second brother, go check if there is a demon core in this thundercloud lion's head?" Cao Jingwen said with a deep frown.

Cao Jingbin nodded, jumped onto the head of the Thundercloud Lion, and stretched his arm through the crack that Chu Qingyun had chopped out.

When the demon beast is alive, no matter what, it is impossible to detect whether there is a demon core, and even the demon beast itself does not know.

However, if the head is split, even if the demon core is taken away, in the short term, some traces will be left in the head.

"Big brother, this big guy still has some thunder and lightning power in his head, and my fingers are numb from the electricity, so there must be a demon core! Damn, someone picked it up cheaply!"

Cao Jingbin dug inside carefully for a while, his face became extremely ugly, and he couldn't help cursing.

The most valuable demon core was taken, leaving a huge corpse for them.

The value of a demon core far exceeds the body of this demon beast, which is equivalent to the fact that they desperately cooked a pot of soup, and at the end of the boil, the meat was eaten by others, leaving them a pot of soup.

"Whoever this man is, he has to die!"

Cao Jingwen, the head of the Cao family, was so angry that his face turned blue, and his lips couldn't help but tremble.

In order to drag down this thundercloud lion, the Cao family can be said to have paid a tragic price, who would have thought that in the end, it would be cheaper for others!

"Father, do you think it could be that kid?" On the side, Cao Meng said with a somewhat grim face.

Cao Jingbin stood on the head of the thunder cloud lion and shook his head, "Impossible, that kid is only a third-level martial artist, even if he has a divine weapon, it is not enough for this big guy to slap him." ”

"What the second child said makes sense, but the possibility of that kid cannot be completely ruled out, after all, in this vicinity, he is the only known outsider. ”

After pondering for a moment, Cao Jingwen shouted loudly: "Pass my order, everyone will go to look for it separately, and send me a signal no matter who they find! Even if the Thundercloud Lion is seriously injured, it is not easy to deal with, that person must have consumed a lot of Yuan Force, and he can't run far!"

After receiving the order from the head of the family, the elite martial artists of the Cao family all formed teams in groups of threes and twos and searched in all directions.

Even in the Cao family, those who dare to walk around the misty forest alone are only Cao Jingwen and Cao Jingbin, brothers, martial artists with a lower realm, and they still have to form a team.

After leaving from the Thunder Cloud Lion, Chu Qingyun was not in a hurry to return to Yan City.

At this time, he needed a quiet place to use the third-order demon core to enlighten the quasi-spirit-level sword and make it a real spirit-level sword.

Learning from Youyun's method, Chu Qingyun found a cave, and after driving a second-order demon beast out, he occupied the cave himself, and also found a boulder to block the entrance of the cave.

The space in the cave was very large, enough for Chu Qingyun to use.

He took some candles from the storage ring and lit the dim candle flames that were planted all around, illuminating the entire cave.

After finding a relatively flat ground in the cave, Chu Qingyun took out a large number of top-grade yuan stones from the storage ring.

According to what Master Jin told him, a complex Enlightenment Formation was laid out on the ground.

After the formation was formed, Chu Qingyun put the sword and the demon core that was still stained with blood into the formation.

After inputting a little bit of his own yuan force into the formation, the entire formation was activated, and the yuan force of the top grade yuan stones was connected by the formation.

The rising Yuan Force dragged the sword and the third-order demon core up.

The demon core is below, the sword is above, and the entire formation is filled with rich yuan power.

Under the refining of Yuan Li, three minutes later, the demon core began to move, and only a small trace of thunder was seen, separated from the demon core, all the way up, floating to the sword, and was absorbed by the sword.

Here we go!

Chu Qingyun showed a relieved smile, he knew that this was the formation refining the demon core.

As long as all the power essence in the demon core is tempered and the sword is absorbed, at that time, the sword can become a real spirit-level divine weapon!

This principle is actually the same as the method that Youyun helped him refine the ice demon core and eliminate the fire poison.

It's just that what Chu Qingyun refined this time was a third-order demon core, and he himself only had the strength of a third-order martial artist, so he needed to use the power of the formation to refine the demon core with Yuan Stone.

As time passed, traces of thunder seeped out of the demon core and were absorbed by the long sword suspended above.

And the size of the demon core is also untraceable, getting smaller little by little.

After absorbing a lot of the essence of demon core power, the dark long sword seemed to have more agility, and there were occasional lightning flashes on the blade.

Everything is going on in an orderly manner.

However, after about fifteen minutes, the Yuan Force output of the formation began to weaken, and the demon core had only decreased by one circle, and it was still too early to be completely refined.

The corners of Chu Qingyun's mouth twitched, there were three thousand top-grade Yuan Stones smashed into it just now, and they only refined so much!

However, Chu Qingyun's movements on his hand were not satisfied at all, and with a flick of the storage ring, he took out a bunch of top-grade yuan stones and top-grade yuan stones, and sprinkled a lot of them into the formation.

He can still accept spending Yuan Shi, but if he ruins this opportunity because of hesitation, then he will waste a third-order demon core and a quasi-spirit-level divine weapon in vain, then he is really stupid!
