DC: OMNITRIX

Gray Matter, a Galvan species, has extremely high intelligence and is basically the most intelligent species in the Ben 10 universe. Azmuth, the inventor of the Omnitrix, is also a Galvan.

A green light flashed, and Yuri's body began to shrink continuously until it was about 15 centimeters tall.

His skin turned gray-blue, his head was inverted triangular, his eyes were round and large and distributed on both sides, and he looked like a walking frog, except with a small mouth.

The changes in appearance were insignificant. At this moment, Yuri's mind was undergoing a dramatic change, with his thinking ability, computational ability, association ability, and deduction ability all increasing countless times. His brain can perform calculations of billions of trillions of pieces of information in an instant.

Although Little Soldier's super brain cannot directly give Yuri knowledge, it can use the simple information he already knows to deduce deeper knowledge.

To give a simple example, if Yuri only knows some basic knowledge of electricity, his brain can automatically deduce basic theorems such as Ohm's Law, Kirchhoff's Laws, Coulomb's Law, Faraday's Law of Electromagnetic Induction, and then extend them to the Law of Charge Conservation, Lorentz Force Formula, and even Maxwell's Equations...

The whole process does not require systematic learning; he can think of these things on his own. The more profound the deduced knowledge is, the longer the time required.

Unfortunately, Yuri himself is not a knowledgeable person, even if Gray Matter has universal intelligence, it cannot make Yuri a technology master all at once.

So he quickly realized a fact, that he could not forcibly hack into Omnitrix like Kenny to remove the protection mechanism. Even the ten-year-old Ben Tennyson couldn't do it.

In Kenny's time, Ben had a very deep understanding of the Omnitrix, and under Kenny's influence, he must have known a lot of information about Omnitrix. Moreover, Kenny's watch was made by Ben, and the encryption level of the protection mechanism must not be as high as that set by Azmuth. 

Not to mention that Yuri seems to have an upgraded third-generation Omnitrix.

"It seems that to remove the protection mechanism, either DNA unlocking must be unlocked step by step, deepening the understanding of Omnitrix bit by bit, or I can only open the control mode by chance, like Kenny did..." 

Yuri thought helplessly to himself, but he didn't feel disappointed. Just half a day ago, his greatest wish was to have a full meal. Now that he had some self-defense power, what was there to be dissatisfied about?

Besides, he had other things to do. He pulled back the compartment of parts he had just acquired; of course, he was going to use them.

He wanted to modify his old and worn-out car!

Although Yuri was small in stature, when it came to handling mechanical parts, he was now a natural. It was effortless for him.

A series of clanging sounds echoed as Yuri astonishingly began to transform the old car at an amazing speed.

The old and dilapidated car body immediately transformed into a brand new one.

Unfortunately, Yuri had bought only second-hand parts, without any high-end fancy stuff, so he couldn't upgrade the old car much.

Especially when it came to the engine, he could only refurbish the aging one, as increasing its horsepower was impossible. However, he could at least guarantee that it wouldn't shut off inexplicably.

The engine of the old car itself was not bad, capable of driving an eight-meter-long box truck. It was just too worn-out. With Yuri's current perspective, he could hardly believe that the engine was still running!

The energy efficiency of the distribution box from the last century was too low; he had to redesign the circuit!

There was also too much wasted space in the car compartment, so he had to dismantle and rebuild it!

All the broken air conditioners and refrigerators were repaired, and all the replaceable parts such as tires, brakes, clutch, transmission, and radio were replaced. 

After ten minutes of charging and transforming, Yuri spent a total of three hours revamping his old car.

Finally, Uri's old and worn-out car was completely transformed.

"Job's done, time to sleep."

Yuri lay on the bed in his newly organized space and drifted off to sleep.

Meanwhile, hundreds of meters underground in Central City, there was a massive base hidden away.

The base was wrapped in a lead-infused super alloy, which not only provided strong defense but also prevented it from being detected by those with X-ray vision.

This base was called "The Network," a black market specifically designed for super-villains to conduct their transactions, and it had been in existence for over fifteen years.

Almost all of the super-villains in Central City and Keystone City had worked with The Network at some point, whether it was for selling stolen goods, money laundering, gambling, medical services, intelligence, or buying equipment. Everything could be achieved here.

And the controller of The Network - you might not believe it - was a woman who call herself "The Blacksmith."

The Blacksmith never revealed her face, and she only focused on running her business. Therefore, her name "The Blacksmith" was only known among the super-villains.

She probably would never go to the surface in her lifetime, but life is always full of surprises.

"This year's revenue has decreased by 27% compared to last year..."

In her office, The Blacksmith looked at the bills submitted by her accountant with an unpleasant expression on her face.

"Boss, ever since The Flash appeared, criminal activities in Twin Cities have been greatly reduced, and everyone has been having a hard time for the past few years, including us...," the accountant sighed and said worriedly, "If this continues, I'm afraid that in the future..."

BANG!

The Smith slapped the table with a hand, leaving a hand-shaped dent on the surface.

"The... Flash..." The Smith pronounced each word with a heavy tone, her eyes filled with intense hatred.

The accountant was scared and sweating profusely, afraid that the blacksmith might slap him in anger.

Thud! Thud! Thud! 

At this moment, a knocking sound was heard, followed by a voice saying, "Boss, the boy is back and he wants to see you."

The accountant was relieved and quickly excused himself.

The blacksmith had been a prominent figure in the underground world of Twin Cities for fifteen years, and she was not easily angered. She quickly regained her composure and said: 

"Let him in."  

Before long, a golden-haired young man wearing a yellow and blue circus magician outfit and a mask walked into the blacksmith's office.

He was Axel Walker, the second Trickster.

The blacksmith, who had been dealing with numerous high-tech equipment for years, recognized Axel's outfit as the one used by the previous Trickster.

The blacksmith, who had been in a bad mood, finally smiled.

"You said that as long as I became a real super villain, I could join the network. Well, now I'm a magician, Blacksmith. It's time for you to fulfill your promise," Axel said eagerly as soon as he entered.

"Look at where you are now. If you haven't joined us, you're already dead," the blacksmith replied.

Upon hearing this, Axel's face lit up. "So, does that mean I'm in now?"

The blacksmith nodded. "I have high hopes for you, young man. You have unlimited potential."

"I have a plan to take down the Flash and take all the wealth in Central City and Keystone City for ourselves."

The blacksmith looked at the excited Axel and continued, "To achieve this plan, I need you to complete a mission..."
