Dr. Kirk Longström has been married for a number of years, and as far as is known, his marriage was exemplaryly happy. So the fact that his wife was actually a commercial spy planted by Cardwell in the first place is indeed a bit unacceptable.

According to the information on the USB stick, Francine first approached Dr. Longstrom as a commercial spy several years ago, and the recording of the doctor's research data has not stopped until now - the last time the data on the USB stick was updated was two days ago.

"There are some valuable clues," Barbara said, flipping through them, "that Dr. Longström had a laboratory registered in the name of one of his former apprentices at the Naho Bridge. If they hadn't given up on their research now, they might be able to be found there. ”

Nai Ho Bridge, one of the poorest areas in Gotham City.

The streets here are dilapidated and narrow, with little room for vehicles to pass through. In a dirty alley, no one could have imagined that in a basement behind a dumpster, there was a major piece of research that would leave a mark on the history of science.

Batgirl huddles behind the Winged Knight, and the two fly through the streets on the Batcart, finding the inconspicuous door to the underground laboratory.

Roy walked down the stairs, followed by Barbara, pinching her nose and saying, "This place stinks, it's unbelievable for scientific research." ”

Roy didn't speak, walked to the bottom of the stairs and stopped, frowned, and reached out to push the rusty iron door, and the heavy iron door opened with such a "creak".

"Not locked?" Barbara is strangely authentic.

Roy pointed to the door lock: "Someone broke it with brute force, and it can't be locked anymore." ”

The two cautiously walked into the room where they couldn't see their fingers, and turned on the night vision devices to observe the situation.

It didn't match what I had imagined before I came, and the lab was in shambles. All kinds of instruments and equipment were smashed to the ground, and a centrifuge left marks that looked like dogs had gnawed, and it fell headfirst to the ground. Even if ten buffaloes were put into this laboratory together, it probably wouldn't be any more messy.

"Ahh Barbara Road.

"Scratches, bite marks." After examining the various injuries, Roy concluded, "It looks like the worst has happened. ”

"Does that mean we're going to have to get Dr. Kirk's help and turn a humanoid batacore back into a human first?" "That's pretty good. ”

She walked to the computer on the table, which was already full of cracks, opened the main chassis that had been deflated, and said helplessly: "It seems that this computer can't provide us with anything anymore, and the motherboard has been caught in a pile of scrap metal." ”

"Forget the computer, look at this."

Barbara approaches Roy, only to see an unidentified device placed there, also connected to a monitor. On the monitor was a map, and a red dot that was centering on itself and emitting some kind of fluctuation was moving around the map at a uniform speed.

"What is this?" Barbara asked.

Roy said: "I've seen a similar machine in Wayne's scientific department, and this one is a machine that captures ultrasound. It can be used to detect objects moving at supersonic speeds, or to locate sound sources that are emitting ultrasound waves. ”

"It's like a big bat flying around in the Gotham sky." Barbara understood.

"It looks like it's spinning around the edge of the Brooklyn Bridge right now." Roy said, "Then we'll have to catch it before it flies away." ”

Brooklyn Bridge Bottom.

The batmobile stopped at the bridge, and Roy and Barbara stepped off and walked towards the riverbank.

There were a few people lying on the side of the bridge pillar. Roy turned one of them over, only to see that his face was full of hideous fear, his frightened eyes widened, and the blood stained the white T-shirt under his coat a blood-red color. Roy ripped off his clothes and found shocking scars on his naked body.

After Roy examined the wound, he whispered to Barbara: "The wound basically matches the animal form of bat minions, but it is an enlarged version, it should be a much larger species than ordinary bats, the category is close to the South American vampire silver-haired bat, and it has a higher attack efficiency than the piranha." ”

"Sounds like the big guy we're looking for." Barbara Road.

Roy continued to examine the wounds on each corpse, some of them even some of their flesh had been torn clean and their bones exposed.

"Wait, Winged Knight, there's another over there." Barbara suddenly made a discovery.

A blonde man with a bare upper body and almost all of his pants torn to strips of cloth fell to the water's edge, his body curled up in a ball, his back trembling and shivering. The two looked at each other and tentatively walked towards the man.

"Don't come here!" The man shouted.

Roy continued to move forward and asked, "Kirk?" Dr. Longstrom? Calm down, we just want to help you. ”

Dr. Longström turned his head, his facial features distorted, and his skin had begun to change from white to brownish-black. He covered his head with his sharp, blackened nails and cried out in pain, "I say...... Leave me...... Far away! ”

The moment he roared, he finally lost control completely, his body suddenly swelled, his eyes released a blood-red light, and a pair of furry wings like fallen angels pierced the flesh and stretched out from his back. The Batman roared angrily, flapping his wings as if he was about to take off.

Barbara, who had been prepared for him to fly away, immediately threw out the bat rope and wrapped it around the batman's ankle, trying her best to press her weight down, shouting, "What's the hurry? Big? We haven't talked about it yet. ”

Just as she lowered her center of gravity and was about to use her whole body weight to resist the force of Batman's flight, Batman swerved abruptly, roaring sharply and charging towards Batgirl.

He's fast, surprisingly fast. The bat girl's pupils closed, and she only watched the sharp fangs get closer and closer, and instinctively dodged to the side, but it didn't seem to be able to dodge the ferocious pounce in time.

At the last moment, Roy pushed her away and raised his hand to block it. The batman bit down on his black fiber glove, its sharp fangs digging in, and Roy could feel the beast's powerful bite almost pierce the protective glove.

The bat girl, who was pushed to the ground by Roy, exclaimed.

The Batman's teeth were so sharp that a little sharper would have pierced the Winged Knight's bulletproof armor, but only a little short. Roy reached out with his other hand with agility and grabbed Batman's throat, knocking him to the ground.

The Batman's strength is equally terrifying, and Roy has unleashed his arm strength to the limit, but he can feel that the Batman may escape at any time. He struggled, his wings flapping out of order, and his mouth kept screaming sharply.

"Cold ...... Quiet...... Doctor, we're here...... Help you...... Yes! ”

When Roy said this, he finally couldn't hold it back. Batman slapped him aside, and he soared into the air like a rocket, disappearing into the night sky.
