The mural features super-large ships, without sails and rocking oars, apparently mechanically powered, and never-before-seen weapons on them, similar in shape to cannons. The mural in the back is a depiction of a naval battle, the kind of weapon in the war is a long-range attack, and there are dozens of people flying in the sky, and there are a large number of demon beasts on both sides participating in the battle.

The mural in the back made Jiang Xingchen exclaim in surprise, he actually saw a submarine, firing a torpedo-like weapon to blow up an undersea cliff. Later on, various novelty devices appeared, depicting the process of excavating this dragon palace.

The mural came to an abrupt halt here, and there were still some behind, but it was already blurred, and there were signs of destruction.

"I really can't imagine that this Dragon Palace was actually built by humans!" The old man muttered, looking indescribably lonely, as if he was stimulated by the content of the mural.

Jiang Xingchen lowered his head and pondered, if the descriptions on the murals were true, then what era was in the painting, it must be older than the era seen in the desert temple, where the description of the murals had already seen great changes in the world, and people's lives were not much different from the present.

Jiang Xingchen couldn't help but think of the previous life, and many people guessed based on some unsolved mysteries that human beings on the earth had experienced several civilizations. For example, a large two-billion-year-old chain nuclear reactor was found in the Gabonese Republic of Africa, scientists believe that it is a natural reactor, but some people speculate that it is a remnant of one of the prehistoric civilizations, and the mural depicts the previous prehistoric civilization.

"If you look at the murals, this is built by humans, how did it become the Dragon Palace? Where did these monsters come from?" The old man gently pushed Jiang Xingchen and asked in a low voice.

Jiang Xingchen came back to his senses and shook his head slightly: "I can't see clearly behind the mural, I can't tell what's going on?"

"Could it be that the mythical beast dove occupies the magpie's nest?" The old man asked again.

"It's possible!" Jiang Xingchen's mouth was perfunctory, but what he was thinking about was something else. Judging from the murals, eighty percent of this battle is to grab the territory and develop the place. But what is there to develop here, is it to place a few formations. It's easy to understand that the dragon clan is snatching here, this high platform can gather vitality, and of course it is good for Xiaolong.

"Woo~" Xiaolong saw the two squatting in front of the mural and ignoring himself, he screamed twice dissatisfiedly, turned his head and saw the demon fox, and swooped over.

The demon fox was paying close attention to the dragonfly behind him, and when he heard the sound of breaking the air, he turned his head and saw the little dragon pounced, and he couldn't help but be startled, and dodged with a dodge.

Promoted to more than thirty levels of eight tails, the strength of the demon fox is far from being comparable to the current little dragon. Xiaolong was a little angry, and he made a twist, and he had to catch up. The demon fox was also angry in his heart, but he didn't dare to really do it, so he could only dodge.

The four private soldiers watched the two demon beasts chasing and fighting, and no one had the intention of stretching out their hands, but just looked at it with a smile. In their opinion, Xiaolong can even accept the name of the meat worm, which means that he has completely surrendered and will not fight with the demon fox.

After chasing for more than ten minutes in a row, he didn't catch up, and Xiaolong was really unhappy this time, so angry that his tail slapped the ground hard.

"Bang!" Xiaolong's tail went down, and the high platform was suddenly photographed out of a big hole, and the colorful light came out, which attracted everyone's attention.

"Sir, this high platform is hollow, and there are a lot of colorful crystals in it!" A private soldier ran over to take a look and shouted loudly to Jiang Xingchen.

Jiang Xingchen stood up, walked a few steps quickly to follow the next look, and suddenly felt dizzy, and saw the crystals full of colorful streamers below.

"I'll make up, how much is this!" The old man also came to Jiang Xingchen's side, looked down, and suddenly exclaimed, and his eyebrows were about to be raised to his head

Jiang Xingchen reached out and grabbed the little dragon who was about to chase the demon fox again, and asked loudly, "Is there a way to go inside?"

"Woo!" The little dragon tilted its head and thought for a moment, then shook its head, it didn't even know that it was empty underneath.

"Boy, what's the trouble going down, and you still need to find a place?" The old man glanced at Jiang Xingchen with contempt, slapped it on the entrance of the cave, and suddenly collapsed a large piece, and then said, "Just jump down from here!"

The corners of Jiang Xingchen's mouth twitched, but he didn't speak. At this time, the more he talked, the more embarrassed the old guy became.

Seeing that Jiang Xingchen ignored him, the old man was quite bored, so he came over and grabbed Jiang Xingchen's arm and jumped directly from the hole.

Jiang Xingchen didn't expect the old man to suddenly make a move, and he was startled, and when he reacted, his feet had already fallen to the ground.

"Boy, how is it? I'm ashamed of you where you still find it!" The old man said strikingly.

"You're cheating, I'm convinced, okay!" Jiang Xingchen replied, ignored him, and carefully stared at the surrounding walls. From above, the cave entrance is full of colors, and I don't know how many colorful crystals. But when I first found out, there were not too many crystals to count, but they were all set on the walls.

"That's right, this is an Induction Control Array!" Staring at the wall for a moment, Jiang Xingchen wanted to jump up excitedly. The position of the colorful crystals happens to be the shape of runes, although it is far less complicated than its own introduction control array, but it is definitely the introduction control array, and there will be no mistake. He could feel many streams of vitality being drawn towards him, and then all the way up, through the ceiling, to the position of the middle platform.

"Could it be that you can put out a rune formation to work, it's unlikely, right?" Jiang Xingchen said secretly in his heart and continued to observe carefully. Sure enough, I found a difference again. These symbols form a closely connected line with each other, which seems to be very chaotic, but in fact it is very regular, and it is difficult to see if you don't know the formation. Moreover, Jiang Xingchen found that the color of the colorful crystals near the ground on the wall was dim, while the upper part was slightly brighter, and the vitality attracted in was gradually compressed in the process of conveying online, and there was a qualitative change.

"It seems that the operation of the formation also requires energy, and the colorful crystals below are almost exhausted, but I don't know how many years this formation has been running, and the consumption is quite small!" Jiang Xingchen said secretly.

"Well, the person who built this high platform is sick, and I have to work hard to cut off the colorful crystals on the wall!" The old man shouted.

"Forget it!" Jiang Xingchen patted the old man and said, "Even if you pick it off, we can't take it away, pull it down!"

The old man looked depressed, he found a lot of yuan stones and colorful crystals here, but he couldn't take them away, it was really painful.

Jiang Xingchen's mood is very good, what he finds here is much more important than those Yuan Stones, go back and study it, and gather Yuan Qi will be endless, and the demon beasts don't have to worry about it anymore. Seeing the demon beasts fighting together with humans on the mural may be the reason for gathering vitality.

"Let's go, let's go up!" Jiang Xingchen greeted the old man and shouted at the top, telling the private soldier to put down the rope.

After returning to the high platform, Jiang Xingchen asked everyone to prepare and continue to explore deeply, firstly, to find a way out, and secondly, he had greater questions. There must be a reason for the great battle between the two sides in the mural and the final development of this place.

Xiaolong had already eaten the eggshell, Meimei burped, and occupied Jiang Xingchen's arms again. Fortunately, this guy is not heavy, and it is not difficult to hold it.

The demon fox finally breathed a sigh of relief, and if the little dragon chased after it again, it couldn't help but do it.

Coming down from the high platform, a group of people continued to move forward, and the old man took the lead, Jiang Xingchen and the private soldiers were in the middle, and the demon fox was broken. Behind them, an army of dragonflies was following suit.

"See, the dragonflies are following, which means that they are the subordinates of the fleshworms. But they don't dare to come closer, is it strange?" The old man shook his head suspiciously.

"Not only did they not dare to approach the little dragon, they didn't even dare to approach the high platform!" Jiang Xingchen turned his head and just saw the dragonfly army bypassing the high platform from both sides, and the distance was quite far, as if they were avoiding the high platform.

"Could it be that the dragon gave them an order not to be allowed to come closer?" The old man asked

"It's hard to say!" Jiang Xingchen shook his head and sighed, "If it's really what you judged, these dragonflies have lived long enough!" Speaking of this, he gave birth to a sense of disobedience.

In the previous life, dragonflies could only live for a summer, but Jiang Xingchen thought of the bees and ants he raised, and he was relieved, this world is not the earth after all, dragonflies are demon beasts above level 20, of course they will not be finished in one summer.

"Boy, can you take these dragonflies out. If you get it, the Star Leader will be invincible, and you can bomb whoever you want!" The old man said with a twinkle in his eyes.

"I'll try it in a while, it's hard to say if it will work!" Jiang Xingchen smiled and nodded.

"Your kind of mist-like vitality shot, how can any demon beast stop it!" The old man laughed.

"That level 30 monster can stop it!" Jiang Xingchen said angrily.

"Eh" The corners of the old man's mouth twitched, and he changed the topic: "Boy, why is there no vitality in this area?"

"I don't know!" Jiang Xingchen didn't say that the matter of the formation was too troublesome to explain. The old man is the kind of character who asks the bottom of things, and he doesn't want to be nagged endlessly by the old man in his ear.

In fact, from Jiang Xingchen himself, he also had a lot of puzzles, because the Yuan Attraction Control Array would not drain the surrounding Yuan Qi, which was something that the Material Exploration Array could do. And why only the vitality behind the high platform was emptied, but the one in front of the high platform was fine, as if the high platform was a dividing line, why this happened, he couldn't figure it out.

After walking forward for more than ten minutes, Jiang Xingchen felt more and more that something was wrong, how could he not have vitality when he arrived here, and it was impossible for the Yuan Attraction Control Array of the high platform to affect so far.

Thinking in his heart, Jiang Xingchen ran the formation and sent the vitality forward. Almost at the moment when he sent it out, he felt a strong suction force pulling the vitality, and the powerful force seemed to pull out the formation in his body. (To be continued.) )
