"Hurry up." Bonnie urged ahead.

"It's coming, it's coming." Chen Feng followed behind, with a smile on his face, and walked down the steps step by step.

Bonnie looked at the evil smile on Chen Feng's face, and suddenly remembered the madness of last night, and her face was slightly red.

The two went crazy in the pet home all night, and as soon as they got up early, Bonnie offered to take Chen Feng to see the underground world of the City of the End, which was guaranteed to surprise him.

Chen Feng readily agreed, so the two walked down from the pet house's passage to the underground world.

"Now, there are many entrances to the underground world, and the new entrances are all very spacious, and troop carriers can pass freely." However, Bonnie quickly entered the state, and introduced Chen Feng as she walked, "It's just that your pet home is special, and I haven't asked the construction department to renovate it." ”

"That's good. If I do need it, I will let the giant worker ants transform it directly. Chen Feng also nodded.

The two of them walked all the way down, about a hundred meters, before they came to the end of the passage, and Bonnie pushed the door open, "Welcome to the underworld." ”

Chen Feng walked out of the door, and his eyes suddenly brightened.

It is a huge 20-metre-high space with a smart lighting system on the dome that almost perfectly mimics natural light, changing in brightness with the alternation of day and night.

As on the ground, wide roads lead in all directions, connecting functional areas and different buildings, where large quantities of strategic materials are stored.

From time to time, a large vehicle full of goods passed on the road, many people were still busy working, and when they saw Bonnie and Chen Feng, they immediately stopped their work to salute them, and Bonnie signaled them to continue working.

It can be said that this place really can be called a "world".

"Wow~" Chen Feng shrugged his shoulders in surprise and spread his hands, "What should I say...... This is really amazing. ”

"Well, I'm doing a good job, aren't I?" Bonnie grinned, only in front of Chen Feng could she show this kind of little daughter demeanor, and when facing others, she would immediately become an all-knowing and all-powerful female archon.

"Of course! I even think that you will be the boss more suitable than me. Chen Feng said in an exaggerated tone.

"Don't!" Bonnie shook her head vigorously, "I'm going to be a boss lady!" ”

Chen Feng was stunned, and then the two laughed together.

The two of them continued to wander the underworld, which was only a small part of the vast underworld of the City of the End, and in Bonnie's plan, the area of the underworld and the above-earth world should be one or even larger.

It is even necessary to build underground transportation corridors from the central area to the first and second satellite cities to open up the connection between the various gathering places.

This is an ambitious project, even larger and more complex than the construction of the façade, and it will take a long time, not in a year or two.

The two of them walked farther and farther away, and finally reached the edge of the underground world, where the hardened materials on the dome and the ground gradually disappeared, revealing the most original appearance of the underground.

Giant worker ants are still working tirelessly, constantly expanding and carving out the area of the underground world.

"Thanks to these big guys, if it weren't for them, it would have been impossible to complete this big project." Bonnie said.

Yes, the existence of giant worker ants, perfect workers and precision operators, is used in the construction field, which is simply open.

As she was chatting, Bonnie's eyebrows suddenly furrowed, and then she smiled, "Boss, there's good news." ”

"Oh?" Chen Feng was stunned at first, and then reacted, this is the information that Bonnie directly received with her ability, which can be said to be a person walking underground, happy from the sky.

"What's good?"

"Sherlock Holmes and Kinna have discovered a new high-energy amethyst mine 50 kilometers west of us, which seems to be quite large."

"50 kilometers so far! This little girl is running farther and farther! Chen Feng was immediately surprised by this incident.

"Don't underestimate her, after Richard left, she found a new bodyguard, and now she's amazing! Otherwise, I don't feel comfortable letting her run around alone. Bonnie smiled mysteriously.

"New bodyguard?" Chen Feng was surprised.

"Just check it out."

……

High-energy amethyst has become one of the most important mineral resources in the city of the end, only a little bit of this metal, added to ordinary iron ore smelting alloy, the quality of the steel produced is enough to kill the top steel of the old era, as a building material is simply perfect.

In terms of black technology armaments, such as pulse rifles, Thor assault boats, and the newly developed Thor airship boats, the application proportion of high-energy amethyst ore has reached more than 50%!

The discovery of a new mine was a major event for the City of the End, and Chen Feng naturally wanted to go there in person.

Coming out of the underground world, Chen Feng immediately summoned a lion on the rooftop of the pet home and flew west with Huang Quan.

The sky is clear and the sun is shining.

It has to be said that since the end of the world, the natural environment has been greatly improved compared to the previous ones.

Soon, several small black dots appeared on the ground, one of which was Jin Na, and the other Chen Feng was a little unsure, or rather...... Don't want to be sure.

The lion landed on the ground, which was backed by a small hill, which was supposed to be where the veins were.

"Brother boss!" Jin Na, who hadn't seen Chen Feng for a long time, pounced on her as soon as possible and gave her a big hug.

"Hahaha, you little girl, it's too dangerous to run so far away!" Chen Feng pretended to be serious and reprimanded.

"It's not dangerous, my bodyguard is amazing!" Jinna pursed her lips and pointed back.

Looking at Jin Na's black and white bodyguard again, Chen Feng had a feeling that he wanted to hide his face and cry, yes, it was Panda!

"Hu?" At this time, Panda was holding a plant with an unknown name and nibbling on it, noticing Chen Feng's gaze, he just glanced back at him, and continued to compete with the food.

Instead, the owl [Night God] and the little fox [Nine-Tails] who were following Panda quickly ran over

These two little cute creatures are the only two contract pets around Chen Feng who have not evolved, and it has been half a year since they were brought out of the zoo in the blink of an eye.

Chen Feng took the opportunity to take a look at the cooldown time of the [Direct Evolution] ability in the system, there were still 2 days.

"Who will evolve when the time comes......

Chen Feng temporarily suppressed this happy trouble, patted the head of the [Night God] affectionately, and touched the little tail of the [Nine-Tails], the interaction of the owner made these two little cute creatures very excited. For the owner, every contract pet has a natural sense of closeness.

Uh, except for Panda.

At this time, Pikabao [Sherlock Holmes] also came out from the back of Jinna's neck and jumped onto Chen Feng's shoulder, constantly waving.

Chen Feng stretched out a finger and teased Pikabao's chin a few times, "It's you little guy who discovered a new ore vein?" That's amazing! ”

"Brother boss, Holmes told me that in addition to high-energy amethyst mines, there are many monsters underground! Be careful! Kina said with wide eyes.

"Oh?" Chen Feng raised his eyebrows, "What kind of monster?" ”
