Gravity Chamber

At the Mingdu Junior Soul Mentor Academy, there were very few boys who could befriend Liuxing without feeling intimidated by his talent and strength.

Previously, there had been Xu He and Xiao Hongchen.

But now, one of them was dead, and the other had graduated.

As a result, there was no one left with whom Liuxing could have a conversation on equal footing.

The rest were just ordinary friends with little interaction.

Some weren't even considered friends at all.

••••

After Class, the six of them headed to Luan Yu's villa.

Among them, only Nana didn't live in the central district of Mingdu.

If their training went late, Nana could just stay over.

They only needed to send someone to inform her parents so they wouldn't worry.

Nana had already told her parents about these friends, and they also knew that it was Nana's friends who had helped their family.

So they had no objections to Nana staying overnight at a friend's house.

"Auntie, we're back! Tianzhen and the others are here too. Hurry up and show us your latest creation!"

Liuxing pushed open the villa's door and immediately called out for Luan Yu.

"I'm in the training room. Come over here yourselves," Luan Yu's voice came from above.

Liuxing and the others looked up and saw a communication soul tool mounted on the wall.

This was a special communication soul tool that Luan Yu had recently developed based on Liuxing's suggestion.

It had functions for detection, video transmission, and voice transmission.

However, its downside was that it only worked within a few hundred meters, making long-distance communication and video transmission impossible.

But it was already quite impressive.

At the very least, this novel soul tool made Xu Tianzhen, Nana, and Ye Guyi marvel in amazement.

Even Gu Yuena couldn't help but take a few more glances at it.

Only Liuxing and Liuying remained unfazed, not only because they had known about it beforehand but also because they had provided Luan Yu with the inspiration for it in the first place.

Not to mention, in their previous world, communication devices with such functions far surpassed what Luan Yu had just developed.

For Luan Yu, a Rank Nine Soul Engineer, technology itself wasn't an issue, research would solve any problem.

The real challenge was inspiration, and when it came to inspiration, Liuxing and Liuying, had an endless supply of ideas.

The large-scale soul tool that Luan Yu was working on now was also based on an idea provided by Liuxing and Liuying.

Looking at the small house made of metal and surrounded by transparent glass, Gu Yuena frowned and asked, "Is this what you called a gravity chamber?"

Liuxing nodded.

Luan Yu placed a small black cube at the corner outside the room, clapped her hands, and looked at Gu Yuena with a smile.

"You must be Gu Yuena, the only one who can truly compete with these two little brats of mine. As expected, you're quite the beauty."

Gu Yuena's face darkened. Why did this human feel a bit like a rogue?

Luan Yu tapped on the transparent glass, her eyes gleaming with excitement as she introduced, "That's right, this is the gravity chamber. I based it on the concept of gravity-control soul skills and fixed the effect onto a soul tool. Right now, it's still in its early stages, but it can already reach up to ten times gravity, which is enough for you kids to train with."

"The gravity level can be adjusted by controlling the soul power output. The more soul power you input, the stronger the gravity. You should start with just one times gravity at first."

"Really? Let me try it out!"

Xu Tianzhen was eager to give it a go.

The gravity chamber sounded fascinating, and she couldn't wait to experience its effects firsthand.

Luan Yu smirked mischievously, opened the glass door of the gravity chamber, and said, "Alright, Tianzhen, you go first."

"What do I need to do?"

Xu Tianzhen stepped inside without hesitation, her face full of curiosity.

As the glass door closed, her voice came through the small black cube Luan Yu had just placed, it turned out to be another communication soul tool.

"Get ready. I'm activating the soul tool now."

Inside the gravity chamber, Xu Tianzhen suddenly tensed up, preparing herself.

A flash of light surged through the chamber, and Xu Tianzhen immediately felt an invisible force pressing down on her.

Her knees buckled, and she dropped to the ground, hands supporting her body as she exclaimed in shock, "So… so heavy!"

Outside, Gu Yuena's eyes gleamed with insight.

She commented in astonishment, "I see. By applying gravity to exert pressure on the entire body, it strengthens every muscle and even the internal organs. This method of body training is truly ingenious."

Hearing this, Liuxing proudly said, "Thanks for the compliment."

Gu Yuena looked at Liuxing in surprise. "You came up with this?"

Liuxing shamelessly nodded. "Of course! A genius like me thought of it."

Liuying rolled her eyes at him. She knew the real origin of this idea, it wasn't Liuxing.

In this world, sure, he was the one who came up with it, but the true inventor wasn't him.

Ye Guyi, on the other hand, didn't care who invented it. She was just excited. "This method is definitely more effective than running or weighted training! If I train in the gravity chamber every day, my physical strength will improve by leaps and bounds in no time!"

However, Luan Yu shook her head. "Too much of anything is bad. While gravity training is effective, overusing it can damage your internal organs, including your heart. That's why you must strictly control your training time."

"After each session, you'll need to take medicine to condition your body, and in some cases, a healing-type Soul Master might be required to prevent long-term injuries."

Everyone understood then, while the gravity chamber was powerful, it required proper support.

A dedicated medicinal expert and a healing Soul Master were necessary, making it an expensive training method that ordinary families simply couldn't afford.

But for Liuxing and his friends, this wasn't an issue at all.

"Uh... did we forget something?"

Seeing how enthusiastically everyone was chatting, Nana weakly raised her hand and asked.

The group of people, including Liuxing, were stunned for a moment before they quickly turned to look at Xu Tianzhen inside the gravity chamber.

At this moment, Xu Tianzhen was lying on the ground in a spread-eagle position, resembling a dried-up salted fish.

Luan Yu quickly turned off the soul device and opened the glass door.

"You guys are too much! How could you just focus on chatting and completely forget about this princess?!"

Xu Tianzhen lay limp on the ground, panting heavily, with sweat soaking her forehead and strands of hair sticking to it.

In just a short amount of time, she was already as exhausted as a dog.

"She's just not used to the gravity change yet. She'll be fine after resting for a while."

Luan Yu checked Xu Tianzhen's body and shook her head.

With a soul master's physical strength, even at their young age, merely doubling the gravity shouldn't have left Xu Tianzhen in such a sorry state.

The main reason was that her body hadn't adapted to the sudden change in environment.

This kind of situation could be resolved simply by using the gravity chamber a few more times.

After Xu Tianzhen, Ye Guyi couldn't wait to rush into the gravity chamber.

Luan Yu had built six gravity chambers specifically for the six of them.

While Liuxing and the others were training inside, she had already instructed her subordinates to prepare medicinal meals.

Though Luan Yu loved money, she wasn't the type to hoard it without spending.

When it came to necessary investments, she was never stingy.

Xu Tianzhen, Ye Guyi, Gu Yuena, each of them had limitless potential.

The resources spent on them were considered an investment, as they would become the greatest support for Liuxing and Liuying in the future.

As for Nana, although her talent was slightly inferior, with proper training, she still had the potential to reach the Title Douluo level.

She could help Liuxing and the others with various matters, and since she was being nurtured from a young age, she would be someone they could truly trust in the future.

Luan Yu was wholeheartedly dedicated to helping Liuxing and Liuying build connections and establish their own foundation.

Watching the young ones struggle in the gravity chamber, Luan Yu rubbed her chin and muttered to herself, "Should I sell the gravity chambers myself, or sell the patent to Illustrious Virtue Hall?"

The basic gravity chamber was classified as a Level 5 soul device, but its manufacturing cost was comparable to that of a Level 7 soul device.

"Forget it, selling them myself would be too much trouble. I might as well sell it to Illustrious Virtue Hall and let that old fox Jing Hongchen take advantage of it."

In the end, Luan Yu decided to sell it to Mingde Hall.

She was aware that the gravity chamber was highly profitable, but its construction wasn't particularly complex.

Any Level 8 soul engineer who saw one could easily replicate it. The key lay in the concept rather than the technology.

The gravity chamber could help low-level soul masters train their bodies and build a solid foundation.

With enough resources, it could even assist them in absorbing higher-year soul rings.

It was certain that the major sects and aristocratic families, eager to strengthen their younger generations, would not pass up such a valuable tool.

As for the price, it wouldn't be a concern for those powerful factions.

A soul tool that could enhance the strength and foundation of the younger generation was worth its weight in gold.

Even if it were sold at the price of a Level 9 soul device, there would still be buyers.

Of course, selling it at such an outrageous price would offend people, unless the gravity chamber became an exclusive, one-of-a-kind item.

Compared to the communication soul device she was researching, however, the gravity chamber was insignificant.

A long-distance communication soul device had the potential to change the entire continent, whether for military or civilian use.

Luan Yu had no intention of selling her invention to Illustrious Virtue Hall, as she knew they would prohibit sales to the original three empires of the Douluo Continent and keep it exclusively for military use, turning it into a trump card for warfare.

However, she had hit a bottleneck in her research on the communication soul device.

She was unable to expand the device's signal coverage. Solving this problem would take years, possibly even decades, and even Luan Yu herself couldn't predict when she would finally succeed.

Time passed as everyone focused on training and studying.

After training in the gravity chamber for a month, Ye Guyi finally broke through to Level 20 soul power.

However, she didn't rush to obtain a soul ring. Instead, she continued training her body while waiting for Xu Tianzhen to break through.

By the time Liuxing and the others turned eight and advanced to the third grade of Mingdu Primary Academy, Xu Tianzhen had finally broken through to Level 20 as well.

This meant that both she and Ye Guyi were ready to obtain their second soul rings.

Before Ye Guyi's breakthrough, Gu Yuena had already advanced and, without relying on gravity training, had successfully obtained a thousand-year second soul ring.

Meanwhile, Liuxing and Liuying had each gained two levels in the past six months, reaching Level 25 as eight-year-old Soul Grand Masters.

Gu Yuena was at Level 24, while Xu Tianzhen and Ye Guyi had reached Level 20. In contrast, Nana lagged significantly behind at only Level 15.

Unlike the others, Nana wasn't born with innate full soul power, so her starting point and cultivation speed were both slower than Liuxing and the rest.

Despite this, Nana had a great attitude. She only felt happiness and pride for her friends' progress.

At the same time, their achievements motivated her to train even harder.

However, talent was something one was born with.

Unless she consumed a rare heavenly treasure, it would be difficult for Nana to catch up to Liuxing and the others.

As Luan Yu had expected, Ye Guyi and Xu Tianzhen's efforts paid off.

Under the guidance of powerful mentors, they both successfully obtained their second soul rings, both of which were thousand-year soul rings.

Since Ye Guyi had trained for a few extra months, after obtaining her soul ring, she immediately advanced to Level 23. Xu Tianzhen, on the other hand, was slightly behind at Level 22.

After all, their thousand-year soul rings had only just reached the thousand-year threshold.

This was a precaution to avoid any risks, if the rings exceeded the limit by even a few hundred years, their bodies might not have been able to withstand it.
