"Of course it's true." Guan Heng said confidently: "Otherwise, the builders here wouldn't be solemnly locking the place with two big doors, right?"

"Yes, it's still your analysis that makes sense." Yan Xin said, looking left and right, and said in her mouth: "Then, where will the real useful things be?"

"I haven't searched for the entire cave, but I don't know where I can. Let's look carefully first." After saying that, Guan Heng had already stepped forward. After hearing her words, the sisters nodded and scattered themselves to find useful clues.

At this moment, Puxing followed Guan Heng and asked, "Brother, where should we start looking for it?"

"First of all, you have to pay attention to the observation yourself and not miss any clues, and start."

Guan Heng intended to train Puxing, the boy, to give advice, so he gave advice. In fact, Puxing is not stupid at all, but likes to hide his cleverness and behave inwardly without showing off. So after listening to Guan Heng's words, he nodded and immediately did as he said.

After counting breaths, Puxing suddenly pointed to the rock wall in front of him and shouted: "Brother, this area does not seem to be formed naturally, and it seems to be traces of artificial transformation."

"Yes, then confirm it quickly."

"Okay." Puxing nodded, and the spear in his palm suddenly slammed the rock wall with the wind. "Bang! Bang! Bang--" It was a time to say that, and soon, the rock wall collapsed immediately, and everyone's eyes were attracted.

"There are holes in the holes. It seems that this is the place to collect truly valuable things, right, brother?"

"Yes." Hearing Puxing's words, Guan Heng nodded slightly, then turned his neck and said to the girls, "Let's go, come in with me."

"Okay." Hearing this, Qing Huang, Yan Xin and the others came over immediately. When everyone entered the back of the rock wall, they found that this was a fan-shaped area, with five small caves on the left, one in the middle, and the other in the right. Guan Heng Road: "Check it one by one."

First of all, there are two caves on the left, and there are indeed five petrified crystal beads placed in each, which are about the same size as everyone has gotten from the heart of the giant beast before.

Guan Heng picked up one of them and smiled and said, "It's not bad. The aura contained in it is very full. As long as you input the earth and Xuan spiritual energy and merge it, it is almost the same as controlling petrochemical abilities. After I check that they have no side effects or harms, you can each bring one or two."

"If this thing is used in conjunction with the Thunder Bead and the Flame Blast Bead, its power will inevitably increase greatly." Guan Heng played with the bead and said, "I just don't know if the Ethereal Toad Cauldron can copy it in batches. If it can be done, we will not lack petrochemical crystal beads in the future."

"Hahaha, a good idea." Ruotao and Gu Sangniao were so excited that they smiled.

Yan Xin urged, "There are three other small caves that have not been checked, let's go over and take a look."

"Okay." Guan Heng nodded, then took everyone to the cave in the middle, and found that it was surrounded by countless metal chains. It would take some time to destroy it all, so he said, "Go to the other two caves first, and look here at the last one."

After counting breaths, everyone found more than ten crystal beads in the two caves, which was quite rewarding.

"As for this place..." Guan Heng came to the middle cave again and said, "Qing Huang, let's cut off all the metal chains together."

"good!"

"Clang clang!" When Qing Huang agreed, he had already pulled out the blue spirit sword. The Hongyun Sword suddenly appeared on the other side of Guan Heng. The two swords were combined and crossed and slashed. The chains in front of him were immediately broken and fell to the ground with the "crank" sound.

"The chains tied up a huge round stone!" Ruotao looked carefully from the side, then shouted in a low voice: "Young Master, can you say that this whole piece is..."

"It may be the raw material for making petrochemical crystal beads." Guan Heng slapped the surface of the rock casually, and the stone immediately buzzed. Then, he said, "It seems that I guessed right, that's it."

"It looks so big. How many crystal beads can this thing make?"

Zhenwen stood under the round stone, looked up and said involuntarily. "That depends on how we can use it." Guan Heng said: "First of all, we have to get this round stone to the ground."

...

A moment later, Guan Heng and the girls brought the huge rock to the ground. At this moment, the demon horn sent a message with a puppet insect, saying that he had also found crystal beads, so Guan Heng went over and met with everyone.

"Is it the gap between these two boulders?"

"Yes, Mr. Guan." said the Demon King: "Little Green Ball and Dogzi found a few crystal beads here. I think the quality is pretty good, but it's too small, so I dare not make decisions without authorization. Please come and have a look with you first."

"Well, then go in and make sure." Guan Heng finished speaking and said to the monkey: "You will know that you have worked hard to endure, right? Go and smash these two rocks."

"Woo-jji!"

With the permission of the owner, the white-browed old monkey was so happy that he suddenly flew to the huge rock, "Bang bang bang! Boom--" The monkey's fist was spitting out, and one of them was smashed into pieces by the monkey's metal short stick. This time it was very satisfying.

"It's the entrance of the cave."

"Go in, go in."

...

After more than ten breaths, the little green cocciferus and the king of corpse dogs led the way in the tunnel. Guan Heng and everyone rushed to the end of the tunnel.

"Squeak, squeak!" The little green cocciferous walking in the front suddenly screamed. Everyone immediately walked over with a sound, and they saw it and the dog constantly scratching a rock wall.

Guan Heng gently tapped the rock wall with his fingers a few times, and then said, "There is empty behind, it seems that the place we are looking for is there."

It was a while, and then it was soon. Guan Heng suddenly pushed forward with his palm, "Lagla... Boom!" Countless earth and rocks collapsed, and before the dust floated up, they were refined and absorbed by the earth palace toad next to him with the mysterious spiritual energy.

Immediately afterwards, the little green cocciferus and the king of corpse dogs rushed in impatiently. It seemed that they had just arrived here, but were blocked by the rock walls. Therefore, as soon as the road was opened, one insect and one dog rushed over immediately.

"Dongdongdongdongdongdong!" But at this moment, heavy footsteps came, just in time, coming towards the insects and dogs.

"Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Woof-Wo

"Huh!" The guy opposite didn't say anything, and suddenly waved his weapon in his palm and hit the dog king hard, scaring it so much that it shook its neck and hid its head and hurriedly dodged. "Boom!" This blow hit the rock wall, causing countless earth and rocks to fly, with a very scary momentum.

"Dog, come back with the little green ball!"
