I Have A Martial Dao World

```

Lu Yao arrived at an abandoned classroom carrying something.

He opened the lead box and took out an ornament with an "eye in the middle of a triangle".

This palm-sized object was the "Star Key" obtained from the Otherworld.

He had tried many methods without any reaction, but the one Zhang Xin gave him had activated.

At this moment, Lu Yao was about to "replay" the process. Zhang Xin had smeared the "Star Key" with radioactive material, so he decided to try the same!

Moreover, he would use even more force!

~~~~~~~~~~~~

Lu Yao placed the "Star Key" on the podium and retreated ten meters, then took out a can-shaped container holding "plutonium-239".

He sent Mind Force into it, only to see the silver can rise from the ground as if held by an invisible hand and slowly float toward the podium.

When it reached the spot, Lu Yao clenched his hand sharply, and under the effect of Mind Force, the can unscrewed itself in mid-air.

The white powder inside immediately spilled onto the "Star Key".

There was very little powder, only about as much as a pill, which was "plutonium-239"!

It could be used as a nuclear fuel and nuclear weapon fission agent and was highly radioactive.

In layman's terms, it meant—it had a lot of kick!

When the "Star Key" touched this substance, at first there was no reaction.

Lu Yao waited patiently and about an hour later, the powder covering the "Star Key" began to diminish, and the rate of decrease accelerated rapidly. In a few minutes, it completely disappeared.

Seeing this, Lu Yao was greatly relieved, "It worked!"

After a short while, the "Star Key" on the podium suddenly lit up and started to float by itself.

As though guided by a precise directive, it flew towards Lu Yao without hesitation.

[Star Key No. 2 charging complete, Star Key No. 3 detected, fusion program initiates]

"The one from the Otherworld is No. 2, and mine is No. 3..."

As Lu Yao pondered this, the fusion had already begun.

The scene that followed was familiar, just like when he lay in the hospital bed; the No. 2 "Star Key" disintegrated in mid-air, turning into countless green dots that flew into his Divine Soul through his facial features.

Right after that, the No. 3 "Star Key" also transformed into light dots.

The two groups of light dots twined around and quickly merged into one, forming a slightly larger "Star Key"

[Fusion complete]

Hearing the prompt, Lu Yao beckoned with his hand, the "Star Key" that could only remain quietly in his Divine Soul now flew out of his eyes, growing as it caught the wind, and appeared in his hand.

He squeezed it a few times, finding the touch to be very familiar; with another gesture, the Pipa Charm appeared in his other hand.

"These two items feel exactly the same, and their materials are almost identical."

~~~~~~~~~

After toying with it, Lu Yao put away the Pipa and began to test the new functions of the "Star Key".

The fusion of two "Star Keys" certainly enhanced its functions.

With a thought, an "operational interface" appeared in front of Lu Yao.

The interface was like a holographic projection, with two planets slowly rotating.

One of them was Blue Star, where he resided, and the other was the Otherworld.

Both planets were shades of blue, with a translucency to Blue Star, while the Otherworld's blue was deeper.

On the operational interface, there was a circular bubble-shaped symbol.

With a mere thought, the "Star Key" immediately prompted:

[Dimension assessment complete]

[Space-Time Bubble activated]

In front of Lu Yao appeared a mirror, rotating slowly in a green vortex pattern.

This was the biggest benefit he had received this time—the Space-Time Bubble, also known as the legendary "Bag Space".

```

Each of the two "Star Keys" corresponds to one world, and once merged, they can create a "space-time bubble" where the flow of time is halted in the crevice between the two worlds' space-time.

This special space-time structure is like a bubble floating in water. The bubble film completely isolates the gas inside the bubble from the water, forming an independent and enclosed space.

Lu Yao immediately grew excited, "Isn't this a Space Ring?"

At the moment, he didn't have much else but plenty of cash. He had brought back 1 million, and had robbed another 2 million, which was quite troublesome to carry around. This was the perfect opportunity to try it out.

Lu Yao raised his hand and tossed a big bag full of cash into the "green vortex-shaped" mirror in front of him.

The objects entering it immediately froze in place, like insects trapped in amber.

And when Lu Yao reached out his hand, he could take the money out again. He was overjoyed,

"This is so convenient! I wonder how much stuff it can hold. If it's a lot, then in a fight, I could just pull out a tank~"

Looking through this green mirror, the space within the space-time bubble seemed very large, about the size of the warehouse he had rented before, more than enough to put in a tank, an airplane, or anything of the sort.

Lu Yao was extremely satisfied with this new function and very happy about it.

But just as he was getting excited, the Star Key issued a warning:

[Current energy remaining: 19%. Please recharge promptly!]

"Energy!" Lu Yao glanced at the interface and indeed saw an energy gauge at the top right corner, which was at 19% at the moment.

He had been too excited to notice after gaining the powerful new feature. Experience tales with empire

"Using the space-time bubble consumes energy!"

There's no such thing as a free lunch, and Lu Yao quickly accepted this fact.

He immediately calmed his elated mood and entered the Spirit Refining State, attentively examining the changes in the Star Key.

~~~~~~~~~~

About an hour later, Lu Yao rubbed his temples and breathed a sigh of relief.

"Opening the Dimensional Door and space-time bubble hardly consumes any energy, but the real consumption of energy occurs when placing or retrieving items in and from the space-time bubble."

"From this, it seems to be related to the volume and weight of the items."

But there was also good news!

Lu Yao held the Star Key and infused it with Mind Force.

The Mind Force was absorbed completely, and the remaining energy went from 19% to 20%.

"Fortunately, Mind Force can recharge the Star Key! But it's very slow, let's say 1% per day at most. If you want to recharge quickly, you need to use 'nuclear fuel' like before!"

"But people like Buteke aren't common, and I think if I want more 'nuclear fuel,' I need to plan ahead."

Taking a deep breath, Lu Yao sprinted toward Marshal's Tank Factory.

There were three more Battle Armors to be received there, which would be perfect for an accurate test of the energy consumption of the space-time bubble.

It was crucial to know—whether one could suddenly whip out a tank during a fight and blast the opponent!

~~~~~~~~~

Having traveled to and from Yukolun several times, Lu Yao was now familiar with the route and no longer needed navigation.

This time he was in a hurry, maintaining a speed of 150 kilometers per hour even with a big bag of money on his back.

The howling north wind wasn't as loud as his movements, as he blazed his own trail through the snow-covered forest, knocking over any trees in his path.

"I am a human-shaped tank myself now!"

He bulldozed his way through and arrived at the factory in no time.

This time, he was welcomed by Semyon, Sanna's father.

This middle-aged man, slim with thick black-rimmed glasses, had much rosier cheeks.

"Lu, I didn't expect you to like humanoid mecha too. This was a hobby of mine when I was young, and now I have the opportunity to design and assemble them myself at this age."

Though he had just lifted his daughter up, Lu Yao was extra polite at the moment, "Thank you for your hard work!"

While talking, the two made their way to the production and assembly workshop for combat vehicles.

Four towering, ferocious beasts stood before them!
