I built the Black Tower City in Sumeru.

Chapter 57 Alchemy: Living Metal, Little Genius Telephone Watch, Strange Dolly.

Make bold hypotheses, verify them carefully. This unknown predecessor exemplified the scholar's pursuit of knowledge with his life, and deserves our respect.

Defeating the Fire Hypostasis is one thing.

Capturing the Flame of the Form alive and then refining it while it's still alive is another matter entirely.

Living metal, a great idea.

Chen Bo thought that he could give it a try when he became stronger in the future.

However, perhaps I can use the "Earth Vein Centrifuge" to purify the Burning Wish Agate and try it out with Amber 1923 alloy.

After one night, the design drawings were basically completed.

After adjusting the parameters, Chen Bo input the drawings into the personal printer, allowing the printer to print the parts at home.

The printing speed is not fast. It takes a day and a night to make these two sets of armor, and in between, it is necessary to frequently fill in the blanks and input the design drawings of other parts.

Print space is limited, and only a portion of the components can be printed at a time.

However, before leaving home, Chen Bo made a few gadgets, including wristbands with communication functions.

The structure of these two bracelets is very simple.

It consists of a long-range communication module, a simple AI module, a power source, a camera, a talker, and a screen.

Chen Bo called it the Little Genius Telephone Bracelet and gave it to Fiona and Cole as a gift.

Early the next morning.

It must be said that in the early morning of Sumeru, the air is moist with the scent of grass and trees and fragrant with spices; the air is quite pleasant.

Chen Bo changed into a set of light sportswear and started jogging to relieve his fatigue.

With the help of the system, Chen Bo only needs to run 5,000 meters to eliminate mental fatigue, so running has become a daily routine.

I feel uncomfortable all over if I don't run for a day.

Luna 1 also ran alongside them throughout the entire journey.

With someone else by my side, running became less boring.

After running five kilometers, sweat soaked his forehead and hair. Chen Bo let out a long breath and felt his mind clear up a lot.

The running route is also designed so that after running 5,000 meters, you'll arrive at the Grand Bazaar, where you can grab breakfast along the way.

This time, I happened to run into Fiona and Cole at the entrance of the Grand Bazaar.

Seeing that Chen Bo had run over again, Farussan immediately advised Cole, "...Therefore, to be a qualified scholar, one must not only have a brilliant mind, but also a healthy body!"

"Look at Anil, he exercises every day, that's a good habit. Cole, why don't you start going for a run with me tomorrow?"

Kolai scratched the back of his head somewhat embarrassedly and explained in a low voice, "Um... Senior Farusan, actually, when we were in the rainforest, I had to patrol the forest with my master every day, and we would walk for most of the day, so I got enough exercise... When we came to Sumeru City, my master told me to rest well..."

The implication was that she wanted to take a break.

"Boss, three servings of Patty Sharan pudding and two servings of pocket bread." Chen Bo walked over with a smile, ordering for the two of them, and then said to Farusan, "Senior, let Cole rest a bit. She's had a tough time in the rainforest; she'll be busy when she gets back."

"I mean, there are definitely busy times."

At that time, Chen Bo will solve the rainforest problem in one go, and Ke Lai will really be busy.

While waiting for the food, Chen Bo flipped his wrist and magically produced two exquisitely crafted silver bracelets.

The bracelet has a simple yet high-tech design with a smooth surface and only a small screen and a button on the side.

"Here, these are for you." He handed over the two bracelets respectively.

"These are some gadgets I made last night using some insights I gained while researching the Void. I named them the Little Genius Telephone Bracelets," Chen Bo explained. "These two bracelets have most of the functions of the Void, but their communication capabilities are much stronger."

"The communication signal has been specially encrypted and strengthened, ignoring distance limitations. Theoretically, as long as we are still on the Teyvat continent, we can contact each other at any time."

"No remnant of Teyvat can stop its signal."

This is no ordinary communication; it's long-range remote sensing communication, a brilliant invention of the club. Even if two people are not in the same galaxy, they can communicate with each other without delay and without the need for a signal base station.

Farusan's eyes lit up instantly.

If she had possessed something like this a hundred years ago, she wouldn't have been missing for a century.

At the very least, it can guide family members and rescue teams to where they are trapped, or allow them to communicate with family members and avoid feeling so lonely.

But is it really that amazing?

"Explain the principle, and I'll analyze it for you. It can't be communication out of thin air, can it? Is it utilizing the energy flow of the earth's veins, or some kind of special elemental resonance?"

"Signals from the void are not that difficult to block."

Explaining the phenomenon of long-distance remote sensing is still a bit too advanced for Chen Bo at present.

Being able to use it and understanding the principles are two different things. Although there are drawings of the long-range communication module, Chen Bo is not yet at the level of being able to understand them.

It's like how everyone knows how to use a mobile phone, but no one knows how to manufacture one.

However, Chen Bo still tried to persuade him: "I don't understand the specific principles behind it either, and I'm not entirely sure about the effect, but you two must make sure you wear them properly. Having an extra means of communication is always a good thing."

The Void also has communication capabilities, but the Sage imposes different restrictions on different people. Higher privileges are only open to a select few, and conversations in the Void are also monitored.

Seeing the two of them put on the Little Genius phone bracelets, Chen Bo joked with a smile, "If I ever get trapped in some remote, forgotten place again, I can use this to call you for help."

As soon as Chen Bo finished speaking, Ke Lai whispered and undermined him, "...It was clearly Anil who was worried about me and Senior Farusan, afraid that something would happen to us so that you could come to our rescue in time."

"After all, I'm in danger right now," she added softly. "Senior Farusan was indeed trapped in the ruins."

Chen Bo was taken aback for a moment, then burst into laughter: "You found out! Anyway, everyone's safety is the most important thing."

"If I get trapped or in danger, I believe Cole will come to my rescue, right?"

Cole nodded emphatically: "Yes."

Cole made a very serious promise that she would protect her cherished friends.

Just then, a loud commotion of gongs and drums and energetic shouts suddenly came from not far away, instantly attracting the attention of the three.

At the entrance to the Grand Bazaar, Dolly and her group of followers unfurled a huge banner with several lines of large characters written on it in the most eye-catching font:

"Breaking News! A genius student from the Shenglun School crosses over to challenge the Miaolun School's mechanical combat competition and wins first place in the preliminary rounds!"

"Complete domination! Luna 1 is far ahead, demonstrating absolute dominance!"

"Revealed! The personal disciple of the centenarian powerhouse, Senior Falushan, and meticulously trained by the strongest mentor!"

One of the guys was still shouting at the top of his lungs: "Don't miss it! The mechanical combat competition is heating up again, and a dark horse has emerged! Rumor has it there's a secret trump card in the next match! Absolutely exciting, don't miss it!"

"You absolutely have to come watch the semi-finals!"
