This palm-sized white bug is white and tender, and at first glance the meat is delicious and rich in protein. As if sensing Holmes' ill intentions towards it, it twisted and desperately drilled into the dirt.

But Sherlock Holmes gave it that opportunity, and as soon as he grabbed the worm by the tail, it was about to send it into its mouth.

"Stop—"

At the moment when the worm was viciously kissed by Pikabao, Chen Feng appeared in time and stopped Holmes.

"Fat Dun, you are a vegetarian, how can you eat such a thing as insects? It's disgusting! ”

After speaking, he put the white worm in the palm of his hand and looked left and right curiously.

Under the influence of the queen worm, the animals of the entire Sunset Mountain have either become its subordinates, or become its food and nourishment, and no one is spared, how can such a small insect be left?

And it doesn't look like it's mutated at all.

Could it be the offspring of the queen worm? Chen Feng also pinched the tail of the insect and hung it up to observe, which was similar to the queen of the worm.

And Sherlock Holmes has been squatting at Chen Feng's feet, staring at it, hoping that the master will not hold it, and the worm will fall down and swallow it directly with his mouth.

"Master, this little worm is not simple, you sign a contract and try it." Xiao Huang suddenly suggested.

"Huh? Sign a contract? ”

Chen Feng was stunned, after getting the Magical Beast Cultivation System, he had never signed a contract with animals outside the pet store. Xiao Huang reminded him now.

But signing a contract requires favorability.

Chen Feng suddenly remembered that there was another one, and bowed his head to the little worm and said, "Hey, little thing, I am your savior, you have to be grateful to me." ”

He grabbed the worm by the tail and twisted it between his fingers, not knowing if he understood it.

Chen Feng simply turned his heart sideways and directly called out the system, "Sign the contract!" ”

"Ding! If the conditions are met and the contract is signed, please name your pet. A system chime popped.

"Damn, I really succeeded!" Chen Feng was surprised and delighted, and immediately began to ponder the name, "What's the name?" ”

"Simply, if you want to drill into the ground like an earthworm, you can call it the Earth Dragon."

Earth dragon is another name for earthworm.

With a good name, the system interface of the earth dragon immediately popped up.

"Contract Pet: Earth Dragon"

"Variety: White King Worm."

"Evolution Level: 0.5."

"Special ability: Underground Walker. It can survive in the soil for a long time and nourish itself through the nutrients of the earth. ”

Yo~ It's actually level 0.5! This little worm is really not ordinary.

Believe it or not, even the name is different, the white king worm, full of domineering.

Chen Feng dug up a large piece of soil, loaded the Earth Dragon into it, and then handed it to a giant worker ant to bring the Earth Dragon back to the farm. These worker ants are definitely good at running errands and helping out, and immediately walked back through the underground passage.

At this point, the mine is completely safe.

Xiu, Senna and the others also entered this underground square, and they all gasped, shocked by the huge corpse of the insect queen.

"It's terrible that this kind of thing can appear in nature, and the end times are really terrible!" Senna had palpitations.

If it weren't for Chen Feng killing the insect queen in time, if its evolution level was raised to another level, it would definitely be a disaster. Imagine what it would be like to have countless mutated bugs suddenly emerge from the land of Dusk Farm.

"Boss, what kind of metal are these purple ores? I've always felt that the glow of this ore is somewhat similar to the small pillar of energy you brought out of the ruins. Xiu crouched in front of an ore protruding from the wall, frowning in thought.

"Oh? It seems so! ”

After Xiuyi reminded, Chen Feng also noticed this, could it be that these ores are related to small energy pillars, or prehistoric ruins?

The strange outbreak of the last days, even if Chen Feng is a human in two lives, he only vaguely knows that the original corpse transformation virus is hidden in the first unearthed prehistoric ruins.

Perhaps, from another point of view, the so-called corpse transformation virus is equivalent to an evolutionary agent, and if someone carries it, it is equivalent to obtaining the qualification for evolution, and corpse transformation may also be [evolution] in another sense.

And Chen Feng guesses that this evolutionary agent is not only acting on humans, birds and animals, all kinds of plants, and even the whole of nature.

In this way, this ore that does not seem like it should exist on Earth can be explained.

"Xiu, let's go Professor Carlos to pick him up, let him bring the mineral testing equipment, and say that an unknown metal ore has been found here." Chen Feng turned his head and ordered.

"Yes, boss!" Repair the order, and immediately rush back in a hurry.

And Chen Feng stayed alone and took Sherlock Holmes around to hunt for treasures.

Xiaopandun really lived up to the name of [Detective], and within two hours, all the large and small vein points in the entire mine cave were found, and from the trend point of view, the mineral reserves are amazing.

In particular, several rare metals, which are very expensive, are necessary for casting cutting-edge materials. This time, Chen Feng sent it.

After a few moments, Professor Carlos rushed over from the Dusk Farm in a frenzy, and the rare earth veins in the middle of the mine had almost turned the scientist's excitement away, and the rare earth mine happened to contain key elements in his ongoing research on energy applications, and there was bound to be a major breakthrough in the next step.

Under Xiu's constant urging, Professor Carlos reluctantly continued to walk deeper, and when he came to Chen Feng's location, as soon as he saw the ores that emitted purple light, the professor's breath was short, and he didn't even look at Chen Feng.

"W-This is ......!!" Professor Carlos trembled and took out the tester from his arms, swept around the purple ore, his eyes were bigger than a light bulb, and Chen Feng was worried that the old gentleman would not be able to bear it.

Carlos checked the data again, took a deep breath, got up and said to Chen Feng: "Boss, although it is only unrefined raw ore, the parameters are already very amazing, more than any known natural metal, once it is processed into alloys, it is definitely a cross-era material!" ”

"Good." Chen Feng nodded, these were all expected by him.

"Professor Carlos, I'll give you a few directions for development. First, I wanted to develop a more powerful hand-held rifle that would completely abandon the current gunpowder design and use an electromagnetic pulse or a small energy column as an energy source. ”

"Second, the energy of the small energy column should be completely spread, not only for Dusk Farm, I hope to lead it to Fox City, in terms of conduction, it can be transmitted wirelessly, or underground cables. In short, I want to build a new energy supply network. ”

"Third, in the case of guaranteed energy supply, increase the application of design, especially war weapons, now the base is not safe, surrounded by strong enemies, we must continue to strengthen ourselves."
