"Hey, what is Black Plague Beast going to do?" Seeing this scene, everyone's eyes were attracted. The moment when Black Plague Beast spit out the brown crystal soul, he rushed over and jumped up, opened his mouth and breathed again, and steadily held the brown crystal soul in the air.

"Huhuhuhuhu-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-swoo-

"Hey, this breath smells of fire spirit and Mu Xuan spirit, right?" At this moment, Gu Sangnu said.

"That's right."

At this moment, Guan Heng nodded and said, "This brown crystal soul has extended strange changes because it combines the spiritual energy of the wood and the spiritual energy of the fire. I think if I can master it well in the future, this object can definitely become a treasure like the colorful round stone of the Tugong Toad, the Thunder Whirl Wood Pill Bead of the Tengbao."

"Hahaha, it would be great if that would be the case." Yan Xin was very happy when he heard this, and then said to Hei Bai, "Did you hear it? Xiao Bai, you got a good baby."

"Aowu!" Hei Bai also shouted with excitement. Guan Heng said at this time: "Okay, in order to make Xiao Bai get used to using the method of using the brown crystal soul, let it follow us for a while. By the way, call out the golden-eyed ancient beast to accompany it."

"Yeah, I think so too."

Hearing this, Yan Xin nodded, and then immediately did as he said, summoning the ancient beast of golden eyes. The black plague and the ancient beast had not come out for a long time to let go, so he seemed particularly excited. He immediately rushed to the side of the treasure-armored drought turtle and the frosty-browed ancient donkey to say hello, and then started playing together.

"Demonic, old monkey." Guan Heng said at this time: "Now the plague poison on the corpses of ancient beasts is gone, so hurry up and collect the cartilage in their bodies."

"Yes, Mr. Guan."

"Woo Ji Ji!" After he said this, the demon immediately led the old monkey over and started his own work.

"Yeah, there is cartilage inside this corpse, please dig it out."

Soon, they gained something, and then they cheered up and continued to work hard. Guan Heng and the girls were still talking about the corpses of ancient beasts.

Zhenwen said, "Brother Guan, do you think the cartilage of this ancient beast can store the power of lightning, right?"

"That's right."

Guan Heng nodded at this time, and then continued: "The e-sports capacity of Lei Fengzhu is not too large, but this kind of ancient beast cartilage is different. If you can think about it and modify it well, it will not be difficult to create better and more convenient props, right?"

"Hehehe, that's it." Zhenwen rubbed her palms and wanted to try it out when she smiled, and she said, "Let me finish this job."

"Okay." Guan Heng took out the ancient beast cartilage he had gotten before and handed it to Zhenwen: "Here, take it for research."

"Hehe, let me take a closer look." As he said that, Zhenwen took Xiao Hei to the side, muttering and watching the structure of the cartilage.

"Hey, don't move around."

"I just pick it up and take a look. I won't ruin it for you. Don't be so stingy." Xiao Hei took advantage of Zhenwen's inattention and pulled up the piece of cartilage. Zhenwen was a little unhappy.

But at this moment, Xiao Hei's expression became a little weird after looking at the cartilage. She pointed to the surface of the cartilage and said, "Hey, why do you notice that there are many small holes in this cartilage?"

"It's true, you observe it very carefully." Zhenwen leaned forward and looked at it, and then continued: "Maybe these small holes are the key to the cartilage of ancient beasts that can absorb and discharge lightning power. Come on, let me study it carefully."

"Yes." At this moment, Xiao Hei's curiosity arose, handed the object forward, and then observed it with Zhenwen.

After more than ten breaths, the demon lord and the white-browed old monkey had investigated hundreds of ancient beast corpses. Sure enough, after the corpse-examination, a lot of cartilage was found.

Guan Heng said: "Put these things first and put them in the Empty Toad Cauldron. Then take them out when Zhenwen wants to use them."

"Toad, please keep it."

"Yes, Master Guan." Hearing this, the Tugong Toad immediately jumped closer and put all the ancient beast cartilage into the toad tripod.

"Now that the ancient beast cartilage has been obtained, I have also got a piece of brown crystal spirit for Xiao Feng. What else should we look for in this deep pit?" Yan Xin asked.

"Let's go around nearby, if nothing else is found..." Guan Heng said this, and suddenly there was a sudden flapping of wings not far away from the opposite side. At the same time, the cry of the mother evil insects sounded: "Master, Master."

"What's wrong, insect mother?" Guan Heng turned his head and asked, "What did you find?"

"I just took Xiao Jin and Huo Xiao to search for an underground fork in the northeast direction, and found that there was a huge black mud there. In the underground area, this kind of thing is very rare, so I think you may be interested in going over and taking a look?" said the insect mother.

"Black mud?" Hearing this, Guan Heng narrowed his eyes slightly. After thinking for a while, he asked, "Did you find anything suspicious besides this mud?"

"The others... I didn't pay attention." The mother of insects said embarrassedly: "I was in a hurry to come back and report this to the owner, so she let Xiao Jin and Luo Zi stay in the quagmire and come back to report the news first."

"Well, it doesn't matter if you don't pay attention."

Guan Heng waved his hand at this time and said indifferently: "Let's go over and take a look now, let's go."

So, the evil insect mother flapped her wings and soared, leading him and other companions to the dark mud under the ground.

...

At the same time, the King of Golden Swords and Guhuang Roar guarded the edge of the underground mud. At this time, Roar emitted a surprise voice: "Huh?!"

"Last brother, what's wrong?" King Jinshu asked casually.

"Second brother, look at the mud area in the north, is there something floating?" As he said that, Gu Huanghou raised his hand and pointed at the other side.

"It seems like it is." King Jinsai looked at it carefully and then said, "Do you want to go over and confirm it? Then go."

"Okay. I'll go back." After saying that, Gu Huang's roar suddenly flapped his wings and soared into the sky, sweeping in that direction.

"Gudu...gudu..." But no one noticed that there was an area in this dark mud that showed a few bubbles every other section, as if something was hidden in the swamp, and that place happened to be where the roar was going.

"Swish swish swish swish!"
