Liu Kai was quite satisfied with the changes in Xiao Hei.

Dogs have an extremely keen sense of smell, and now Xiao Hei's body seems to have been enhanced as well.

Thinking of this, Liu Kai quickly tore off a tattered piece of cloth from the Japanese soldier's uniform.

He called over Little Black, who was having a great time playing.

While stroking the dog's head, he held the rag to its nose.

"Little Blackie, come and smell this scent, and see where it comes from."

Although it couldn't understand human speech, Xiao Hei seemed to understand Liu Kai's meaning.

He twitched his nose and carefully sniffed the aroma.

He immediately got up and ran happily towards the Japanese soldier's corpse beside him.

To Liu Kai's astonishment, he bit off the index finger of the corpse's right hand.

He obediently sat down in front of Liu Kai again.

He spat out his index finger from his mouth, grinned widely, and stuck out his tongue, looking like he was asking for praise.

Liu Kai held his forehead, utterly speechless.

The stupid dog understood what he said, but not completely.

"No, Xiao Hei, I asked you to find the route. Do you understand what a route is? Where did they come from?"

This time, Liu Kai gestured wildly as he spoke.

Little Black tilted its head and stared at it for a long time.

As if it understood again, it darted out once more.

This time, it brought back an ear.

Liu Kai's lips twitched, but he patiently explained again.

However...

Toes, clothes, shoes, and finally even a bitter tea seed.

The Japanese soldier's corpse was so badly mutilated by Xiao Hei that it was a gruesome sight, with not a single piece of flesh intact on his body.

finally.

The black cat, Xiaobai, who had been watching the show from the sidelines, couldn't hold back any longer.

It jumped directly onto Xiao Hei's back and slapped the stupid dog's head with both paws.

"Slap! Slap!"

"Meow!"

With a cryptic cry from Xiaobai, Xiaohei suddenly paused.

Then, as if suddenly realizing something, it barked twice.

It happily circled around Liu Kai twice, then carried Xiaobai and ran eastward down the street without looking back.

This operation left Liu Kai dumbfounded.

He became even more certain of his earlier guess: indeed, both cats and dogs had been enhanced.

However, this kind of enhancement is very strange.

The dog, which should have been more intelligent, had its body enhanced.

Cats, which generally have lower IQs, actually have their brains enhanced.

And it seems that some strange bond has been established between them, like a mutual understanding.

"Tsk tsk, this is illogical, so illogical..."

Liu Kai quickly gathered up the guns and ammunition scattered on the ground.

Shaking his head and sighing, he chased after the direction Xiao Hei had run.

...

In the current extremely cold weather, Huskies, as sled dogs, have a natural advantage.

With improved physical fitness, he ran with great speed and showed no signs of fatigue.

Because Xiao Hei led the way through many twists and turns, sometimes passing through narrow streets and alleys.

This dissuaded Liu Kai from continuing to drive, and he obediently followed behind the dog, running all the way.

However.

The more Liu Kai ran, the more he felt something was off.

This road seems familiar... why do I feel like I'm getting closer and closer to "that place"?

really.

Xiao Hei finally stopped beside a wide street.

Liu Kai looked surprised.

It really was this place: near the Sky Tower.

Before him stood the enormous crater from the collapse of Metro Line 3!

Although Xiao Hei doesn't seem to be very intelligent, it still has a basic sense of vigilance.

Instead of crawling into the dark hole, he sat by the entrance, panting heavily.

Liu Kai was somewhat surprised and asked in a low voice, "Xiao Hei, are you sure this is the place?"

Xiao Hei couldn't understand.

He just kept nudging Liu Kai with his head, signaling him to get down.

The passage below is quite complex and extends extremely far.

Liu Kai's scan only revealed more disordered footprints than before, but no living person was found.

After thinking for a while, he squatted down.

"Little Black and Little White, it's very dangerous down there. I need to put you in a safe place beforehand. Don't resist."

They still couldn't understand, but they could sense their master's emotions.

So when Liu Kai tried to put them into his storage space, he only resisted instinctively.

It immediately released its resistance and vanished in an instant.

Although Xiao Hei's performance in the battle just now was very impressive.

But that's based on the premise of a surprise attack and a small number of people.

We don't know how many people are below, or what weapons they have.

He decided to travel light.

They decisively launched a full-scale scan and cautiously entered the dark cave.

Stepping back into familiar territory, Liu Kai couldn't help but marvel at how clever these Japanese soldiers were.

After the authorities found nothing amiss, they stopped caring about it and had no energy left to deal with it.

Unexpectedly, these Japanese devils played a trick of hiding the truth in the dark.

Continue along the tunnel.

With the help of exoskeleton smart glasses, he can easily see the direction of footprints on the ground.

Even without Xiao Hei's help to smell the scent, they still chose the most correct path.

It wasn't near the tunnel boring machine where Chen Bin and his group had been, but inside a deeper and more distant tunnel.

In just a few minutes, after turning three corners, the scanned area already contained the shadows of living people.

Inside the tunnel 180 meters away.

The six armed guards were still armed with Howa Type 20 rifles.

Liu Kai's spirits lifted: This is definitely the place!

However, he stopped in his tracks.

Because the thermal imaging mode easily spotted the five horizontal infrared rays in front.
