A Scientific Urban Detective

The "Railgun" is, after all, just an attack that projects projectiles. Electromagnetic force can do it, and so can Nen ability. And Nen ability is also very fast.

Lin Wuming had tested it himself and found that pure Nen ability could be said to be an extension of his will. With just a thought, Nen ability arrives instantly, with almost no time delay. It can be said that this is actually a rather "idealistic" ability.

Specifically, Nen ability is also a kind of "force." In the absence of a load, the concept of "speed" does not exist.

So, theoretically, as long as the acceleration distance is long enough, Lin Wuming's Nen ability can also accelerate projectiles to near the speed of light.

Currently, Lin Wuming's controllable distance is only fifty meters, but if the mass of the projectile is not large, it can also be accelerated to a very exaggerated level.

Small steel balls with a diameter of less than one centimeter are just right.

Lin Wuming used Nen to lay a "barrel" for acceleration, fifty meters in length, directly against the armor of the research institute's front door.

Then, he launched the small steel ball—Nen-powered Railgun!

In just fifty meters, with extreme acceleration, the muzzle velocity of the small steel ball reached a terrifying thirty times the speed of sound! In reality, what was ejected at the end was already a blazing stream of molten metal.

With a thud, the armor at the research institute's gate suddenly exploded.

Due to a lack of professional equipment and experience, Lin Wuming was not sure how much power his "Nen-powered Railgun" could unleash. He could only accelerate the small steel ball as much as possible according to his feeling to increase its power.

To ensure destruction, the second small steel ball was already ready to be launched—although such an operation put a relatively large burden on Lin Wuming's brain and mental power, it was not impossible to achieve a rate of fire like an automatic pistol if he gritted his teeth and persevered.

—He could probably last for another dozen shots. In any case, tearing down this door should be more than enough.

However, somewhat unexpectedly, only the first "Nen-powered Railgun" was used to directly blast open the door.

Or rather, to create a hole about half a meter in diameter in the door panel armor.

The rest was easy. Using this hole, Lin Wuming's Nen ability had a fulcrum, and he tore the door open in a few strokes.

"That attack just now was really amazing!" Kohaku Toumi sincerely praised, "Its power is comparable to an anti-tank missile."

Lin Wuming calculated the thickness of the door and the outer armor plate and felt that her judgment was accurate.

"In any case, let's go in quickly." Lin Wuming propelled his wheelchair forward. "The commotion just now was too loud; it must have alerted the people inside."

Kohaku Toumi revealed a serious expression and licked her lips: "The battle has begun!"

Lin Wuming sped up and walked in front of the girl, instructing, "The enemies have guns. Stay behind me; I can deal with bullets."

Kohaku Toumi raised an eyebrow, but then, thinking of Lin Wuming's performance when facing those armed security guards in the "Black Moon Technology" underground training ground, she stopped being stubborn. Instead, she lowered her body slightly, completely hiding behind the wheelchair.

Lin Wuming took a deep breath and entered the research institute.

Fortunately, the interior of the research institute was already in chaos. The researchers who supported using Haruaki Usumi and the researchers who wanted to kill her had started an internal war. The armed security forces who directly obeyed the researchers were also in chaos, not knowing whose orders to follow, and even attacking each other.

There were also some people searching everywhere for the escaped test subjects, taking advantage of the chaos—only on this point did the two sides seem to reach an agreement.

However, on the test subject's side, the Koga ninja Tsurigane Saryo was secretly acting, either provoking disputes between the two sides or directly assassinating, steadily and efficiently reducing the number of enemies…

In such a chaotic situation, no one paid attention to the two who broke into the research institute for a while.

After being on guard nervously for a while, Kohaku Toumi released her superpower: "What's going on? There aren't any enemies at all. How boring…"

Lin Wuming took out his phone, hesitating whether to call Akakawa Reiza.

The huge research institute had turned into a chaotic battlefield. It was quite difficult to find a few little girls in it.

However, Lin Wuming didn't know the current situation of Akakawa Reiza and the others and didn't dare to call rashly.

"Are the people in this building crazy?" Kohaku Toumi said, "The battlefield we passed just now was just them killing each other."

"There's probably some reason," Lin Wuming said. "Next, we'll move closer to the place with the most gunfire. We should find something."

Kohaku Toumi nodded and was about to say something when she heard an explosion from directly above.

"Grenade, on the floor above." Kohaku Toumi judged. "Damn it, are they really treating this place like a battlefield?"

Lin Wuming was also confused. How did these people get these weapons and equipment?

The two began to move, heading towards the location of the explosion upstairs.

As a result, they saw nothing but a mess.

That explosion also seemed to have awakened the people who were fighting each other, and the commotion in the building suddenly subsided, forming an unsettling silence.

"Be careful." In the eerie atmosphere, Lin Wuming didn't dare to relax and reminded her again.

"I know." Kohaku Toumi narrowed her eyes slightly, mobilizing all her senses to guard against the surrounding environment.

Da da da da da…

In the silent environment, the sudden sound of gunfire was particularly clear.

Lin Wuming immediately looked up: "Upstairs!"

There was reason to suspect that the gunfire in this situation could only mean that the armed security guards had found their target—the children who were escaping!

Those attracted by the gunfire were not only Lin Wuming and Kohaku Toumi but also the others in the research institute.

Finally, in a corridor, Lin Wuming and the research institute's armed security guards made their first face-to-face contact.

The other side raised their guns to shoot without thinking, but before that, Lin Wuming had already opened the storage box, and ten small steel balls flew out with a sharp whistling sound.

The armed security guards fell down in pain, and the bullets fired during that time flew to who knows where.

When the distance closed, Lin Wuming used Nen ability to grab an enemy and used his body as a weapon to smash wildly into the enemy group.

After delaying for a few seconds, Lin Wuming cleanly and neatly solved this group of enemies, successfully passing through.

Soon, after passing a corner, he saw several white-coated researchers leading a team of armed security guards rushing towards them.

Having had the previous experience, Lin Wuming's response was even more skilled, not giving the other side a chance to be surprised, and more than a dozen small steel balls roared out again.

Then, the two quickly passed through…
