The earth dragon broke through the ground, and on the armor-like shell of its whole body, a ball of flame-like heat suddenly appeared, and for a while, a radius of hundreds of meters was like a steamer.

Moreover, the whole body of the earth dragon was also trembling violently, and even patches of cracks faintly appeared on the armor, and it seemed that it was about to molt.

Chen Feng was surprised and delighted when he saw it, and shouted loudly: "Charlie, Carl, quickly command your people to retreat!" The equipment has also been moved a little farther away! ”

Everyone immediately sprang into action and vacated a space the size of a stadium.

Clusters of solid heat continued to emerge from the cracks in the Earth Dragon's shell, and Chen Feng deduced that after eating all the monsters underground, he had accumulated a large amount of fire-based energy, which was enough to start evolution.

He opened the system layout, and sure enough, it was displayed in the status bar of the Earth Dragon: Evolving!

50 long, like a train, the giant tail of the imperial sandworm flicked, bombarded the ground, and the big truck a hundred meters away was turned upside down, the power is incredible!

Then, the huge spikes on the carapace of the emperor sand worm began to fall off, replaced by jet-black, harder armor, although there were no blade-like spikes, but there were many irregular bulges on the surface, and the defense and speed of movement underground had been qualitatively improved.

It also increased in size, doubling its size, from 50 meters to 100 meters before stopping. If it used to be like a train, now it's like a giant ship!

The upper body of the Emperor Sandworm suddenly rose up, a full thirty meters high, and its huge mouthparts opened out in all directions, revealing a circle of thousands of sharp teeth, reflecting the cold light of Sen Ran!

"Roar—"

With a loud roar, the Emperor Sandworm declared its evolution complete.

"Contract Pet: Earth Dragon."

"Variety: Imperial Sandworm."

"Evolution Level: Level 4."

"Special ability: Underground Walker. You can walk freely through the earth and absorb the nutrients of the earth to nourish yourself. It is extremely fire-resistant, and it is not afraid to encounter underground magma. ”

"Special ability: Tunneler. Huge and spacious tunnels can be dug underground to serve as your own dwelling and paradise. ”

"Special ability: Underground Detection. It can detect movements in the underground world hundreds of kilometers away. ”

"Special ability: Ambush. Can break through the ground and launch a surprise attack on prey on the ground. ”

"Special ability: Inner World. In the body of the emperor sandworm, there is a huge organ that allows life to survive in it. ”

【Inner World】!

After the Emperor Sand Worm evolved to level 4, the biggest change in addition to its size was the addition of this special ability. Oh, there is another one, that is, there is a special explanation for the ability of [Underground Walker], and the underground magma cannot pose a threat to the Emperor Sandworm.

Chen Feng was in a state of excitement, the creation of the [Inner World] meant that he could completely build a moving underground palace in the body of the Emperor Sandworm!

Combined with the super mobility of the Imperial Sandworm underground, as well as the super fire resistance, the whole earth will no longer have any secrets for him!

"Great!" Chen Feng waved his arms excitedly.

At this time, Carl also walked over with great courage, and looked up at the Emperor Sandworm with a look of amazement, "Boss, could it be that this guy is the one who wiped out those monsters cleanly?" ”

"Congratulations, you got it right." Chen Feng said with a smile, and then beckoned into the distance, "Hey! Charlie! Would you like to come with me to the depths of the vein? ”

Charlie looked at the huge wheel-like body of the earth dragon, as well as the huge and terrifying mouthparts, and still had some fear in his heart, but the boss called, so he could only come over hard, "Boss, how do we go down?" ”

Before Chen Feng could answer, Carl also said, "Boss, I'm going too, take me one!" ”

Chen Feng glanced at him with a smile, "Okay, Earth Dragon, let's go!" ”

Rumble!

The head of the earth dragon fell to the ground, and its huge mouthparts were opened, and its sharp teeth grew into its mouth like a forest, revealing a path.

"Please?" Looking at the two who were a little stunned, Chen Feng smiled evilly.

"The owner...... What do you mean? No kidding~~" Charlie said tremblingly.

"Boss! Stop playing us! How the hell is it going to go? Carl was even more weeping.

Chen Feng's face was blank, "Are you kidding? Who is kidding! It's to go into the belly of the earth dragon! Otherwise, how to get down? ”

Charlie and Carl glanced at each other, and they could see the deep fear in each other's eyes, and the word "refuse" was clearly written, but under the boss's "obscenity", they still took a few steps forward.

Charlie was the first to turn around, "Boss, I think I don't have to go down, or I can set up a mining machine and go down, just a little slower than you." ”

Carl also stopped and nodded heavily, "Yes, boss, with the earth dragon as your bodyguard, it doesn't make sense for me to follow, it's better to help you release the wind on the ground." ”

Chen Feng smiled evilly, "Is it so terrible? Not only is it not dangerous, but it's also very comfortable! ”

The two of them nodded like garlic, but they didn't notice that their backs were already shrouded in a huge black shadow.

Chen Feng grinned and pointed, "Opposition is invalid, enforce!" ”。

The emperor sandworm opened its big mouth, with a diameter of more than ten meters, and suddenly devoured it downward, the two of them could not avoid it at all, and they were swallowed directly, Chen Feng also flashed, and took the initiative to stand beside the two.

Hearing a boom, the Imperial Sandworm broke through the ground and disappeared from everyone's field of vision.

On the ground, Charlie and Carl's men looked at each other, "What happened just now?" The boss, Minister Charlie, and Master Karl were all swallowed by that giant sandworm!? ”

"No, it won't! The big bug killed people and fled with goods? ”

"Uh, what do we do now?"

"Hmm...... I guess it's good to wait here. ”

……

In the body of the emperor sandworm, Charlie closed his eyes and let out a scream, Carl's ability to bear it was a little better, but his face was also pale.

With this look, Chen Feng couldn't bear to tease the two of them anymore, and hurriedly relieved, "Hey, open your eyes and take a look, isn't it very comfortable here?" ”

"Huh?" Only then did the two of them come back to their senses, they were already in the body of the emperor sandworm, and when they looked around, the light was bright, the air was circulating and dry, there was no smell, and they couldn't feel that it was in the animal's body at all.

"This, this is amazing, isn't it?" Both exclaimed at the same time.

Chen Feng smiled, "Charlie, my imperial sandworm can not only go to any deep place underground, magma can't stop him, but also be responsible for insect removal, this mine was entrenched by a kind of eyeless monster before, and it was wiped out in half an hour." If you encounter any problems in underground engineering in the future, remember to look for him. ”

Charlie's eyes lit up with excitement when he heard this, and the original trace of fear and discomfort had long since disappeared.

The Imperial Sandworm went all the way down, and every once in a while, a few people were released to observe the trend of the ore vein and the underground environment, and this was repeated several times, and after two hours passed, a few people returned to the surface.

According to Charlie's preliminary observations, the reserves of high-energy amethyst ore in this vein are more than several times that of the Sunset Mountain vein and the Zijin mine combined. Simply amazing!

Thundered!

When the imperial sandworm broke through the ground again, opened its mouth, and the three of them came out of it, the onlookers breathed a sigh of relief.

"I'll just say it's okay."

"To be honest, I really want to experience it!"

A burst of whispers reached Charlie and Carl's ears, and the two of them were also proud.

"What are you still doing! Hurry up and get started! Charlie ordered loudly, "Start digging from where I'm standing, there's a natural tunnel here that can save a lot of work!" ”

With the experience of the underground trip just now, the construction of this mine will definitely achieve twice the result with half the effort.
