Lu Yao brought his things to an abandoned classroom.

Open the lead box and take out an ornament with "eyes in the middle of the triangle".

This thing as big as a palm is the "star key" derived from another world.

I tried many methods but didn't respond, but what Zhang Xin gave him was activated.

At this moment, Lu Yao was about to "review". Zhang Xin applied radioactive substances to "Star Key" and tried it himself!

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

Putting the "Star Key" on the podium, Lu Yao retreated ten meters and took out the canned container containing "Plutonium-239".

I found the power of my mind and immersed myself in it, and saw the silver jar flying off the ground, as if it was held by an invisible hand, slowly floating towards the podium.

When he arrived at the place, Lu Yao clenched his hand suddenly, and under the influence of the power of his mind, the jar was unscrewed out of thin air.

The white powder contained inside was immediately poured on the "Star Key".

The amount of powder is very small, only one pill is as much, it is "plutonium-239"!

It can be used as a fission agent for nuclear fuel and nuclear weapons, and has strong radioactivity.

In layman's terms, it's very strong!

As soon as "Star Key" came into contact with this thing, there was no reaction at the beginning.

Lu Yao waited patiently. After about an hour, the powder covering the "Star Key" began to decrease, and the reduction was getting faster and faster, and it completely disappeared after a few minutes.

Seeing this scene, Lu Yao felt relieved: "It's done!"

After a while, the "Star Key" placed on the podium suddenly lit up and then floated up on its own.

As if he was guided accurately, he flew towards Lu Yao without saying a word.

【The star key 2 has been charged, the star key 3 has been detected, and the merge program begins】

"The one in another world is No. 2, is mine a No. 3..."

When Lu Yao was thinking about it, the merger had already begun.

The next scene was very familiar, just like when lying on the hospital bed, the "Star Key" of No. 2 disintegrated into the air and turned into countless green light spots and flew into the soul along the facial features.

Immediately afterwards, the "Star Key" of No. 3 also turned into a spot of light.

Two balls of light spots quickly merged into one after two circles, forming a slightly larger "star key"

【Merge completed】

Hearing the prompt, Lu Yao stretched out his hand and said, "Star Key" that had been able to stay in his soul for a quiet time, but now he flew out of his eyes and saw the wind rising and appearing in his hand.

After pinching it a few times, it felt very familiar. With one move on the other hand, the pipa magic weapon appeared.

"These two things feel exactly the same, and the materials are almost the same."

~~~~~~~~~~~

After playing around, Lu Yao talked back to the Pipa and began to test the new function of "Star Key".

The merger of the two "star keys" will definitely enhance the function.

As soon as the thought moved, a "operation interface" appeared in front of Lu Yao's eyes.

The interface is like a holographic projection, with two slowly turning planets.

One of them is the Blue Star where he is, and the other is another world.

Both planets are blue, the hometown is blue and transparent, while the other world is blue and deeper.

On the operating interface, there is a round bubble-shaped symbol.

Just think of it, and the "Star Key" prompts immediately:

【Dimensional calculation is completed】

["Space-Time Bubble" is turned on]

I saw a mirror appearing in front of me, slowly rotating in a green vortex shape.

This is the biggest benefit obtained this time - the space-time bubble, which is the legendary "backpack space".

The two "star keys" correspond to one world. After the merger, you can create a "time and space bubble" with a stop in the time rhythm of the two worlds.

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

Lu Yao suddenly became excited: "Isn't this the space ring?"

At this time, there was nothing else in your hand, but it was a lot of cash. I brought 1 million back and robbed 2 million. It was a big trouble to hold it, so I just wanted to try it.

Lu Yao raised his hand and threw a large bag of money into the "green vortex" mirror in front of him.

The object immediately solidifies and stops when it enters it, just like a small insect in amber.

When Lu Yao stretched out his hand, he could take out the money again. He was immediately overjoyed:

"This is so convenient! I don't know how many things I can hold. If I install too much, I will take out a tank when I have a fight in the future~"

Looking from this green mirror, the space of time and space bubbles is very large, similar to the warehouses rented at that time. It is more than enough to put a tank, an airplane or something.

Lu Yao is very satisfied with the new function and is very happy.

But just when he was excited, Xingjiu issued a warning:

[Current energy remaining: 19%, please recharge it in time!]

"Energy!" Lu Yao looked at it and saw that there was indeed an energy groove in the upper right corner of the interface, and only 19% was left at this time.

I was so excited after getting the powerful new features and didn't even pay attention to it.

"Using space-time bubbles requires energy consumption!"

There is no free lunch in the world, and Lu Yao quickly accepted this.

He immediately put away his impetuous state of mind that had become too surprised, entered the state of refining the spirit, and carefully checked the changes of the "Star Key".

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

One hour later, Lu Yao rubbed his eyebrows and breathed a sigh of relief.

"Open the dimension door, the space-time bubble will almost consume energy. What really consumes energy is to put it into the space-time bubble and get something."

"From this point, it should be related to the volume and weight of the thing."

But there is good news!

Lu Yao held the "star key" and immersed himself in the power of his mind.

The power of the mind was immediately absorbed completely, and the remaining energy also changed from 19% to 20%.

"Fortunately, the power of the mind can charge the star key! But it's very slow, even 1% per day is better. If you really want to be fast, you have to use 'nuclear fuel' like you did just now!"

"But people like 'Butko' are not common. I want to get more 'nuclear fuel' and have to make a long-term plan."

Taking a deep breath, Lu Yao ran towards the Marshev Tank Factory.

There are three armors to be received there, which can accurately test the energy consumption of space-time bubbles.

You must know clearly whether you can take out a tank during a fight~ and thrust the other party!

~~~~~~~~~~~

Yukolun has run back and forth many times. Lu Yao is now familiar with the road and no longer has to drive navigation.

This time I ran very fast, and even with a big bag of money on my back, it maintained a speed of 150 kilometers per hour.

The howling north wind was not as loud as him. He directly set out a road in the snow-covered woods, and the trees blocking in front of him were directly broken.

"I am a personal tank now!"

I rushed to the road like violent demolition, and soon arrived at the factory.

This time we welcome Sanna's father, Xie Miao.

The thin middle-aged man with thick black-framed glasses has turned a lot rosy.

"Lu, I didn't expect you to like humanoid mechas too. This was my hobby when I was young. I actually had the opportunity to design and assemble them by myself at this age."

He just picked up his daughter in the air, and Lu Yao was particularly polite at this moment: "Thank you for your efforts!"

As the two of them talked, they came to the chariot production and assembly workshop.
Chapter completed!
