As a Mecha, I Can Evolve Unlimitedly

"Douzi, turn the flashlight to strong light mode."

Sato Yuo and Douzi stood closely together and walked cautiously towards the inside of the mountain.

Ever since the two of them stepped into the tunnel, the sunlight had been blocked from the entrance. If they hadn't brought a portable light source, they would have been plunged into darkness before long.

A cold and humid breeze blew across Sato Yuu's determined face. Before the two of them left the cave entrance, he quickly took a look at the surrounding environment with his hand.

The tunnel structure is made of gray rectangular stone bricks. Judging from the raised particles and moss on the stone bricks, the air raid shelter should have been built before the fourth technological revolution.

Sato's gaze followed the light in his hand to the top of the tunnel, and he discovered that there was a black cable embedded in the gap between the stone bricks, and every ten meters you could see an old-fashioned chandelier hanging on the cable. .

These chandeliers were originally supposed to be responsible for lighting the air raid shelters, but for some unknown reason, they failed to light up when humans needed them.

This actually adds a bit of eerieness to the tunnel.

Looking at the dust and gravel on the ground, Sato Yuo silently installed the flashlight on the sling of the heavy pistol, and took out a tactical dagger and placed it under the hand holding the gun.

clatter! clatter!

Sato Yuo and Douzi walked side by side, one tall and one short. Both of them moved at the lightest pace, but the sound of combat boots stepping on debris still echoed in the deep corridor!

At this time, they had advanced two hundred meters into the depths of the tunnel, and the bright entrance had already shrunk into a white light spot the size of a fist behind them.

"Huh..." Sato Yuo exhaled a breath of white air from his mouth. He could clearly feel that the temperature around him was dropping sharply.

As for Douzi walking beside him, he would shiver from time to time.

At this moment, Sato Yu suddenly felt Douzi poke him with his elbow, so he immediately looked at the location where Douzi's flashlight was shining.

A pool of dark red blood was lying quietly on the dirty floor tiles!

This made the two of them instantly alert.

While Sato Yu moved forward cautiously, he slowly shone the light of his flashlight in the direction where the blood stains spread, until they encountered the first fork in the road.

"The blood stain extends to the right, but the faint sound of airflow can be heard in the tunnel on the left." Sato Yu stood in the middle of the intersection, carefully thinking about what might happen in both directions.

Since the sound of airflow can be heard in the tunnel on the left, there is a high probability that the road here is not a dead end. However, considering that ordinary air raid shelters only have two entrances and exits, Sato Yuo does not believe that he can get through here before he sees the evacuation area. Way out.

As for where the back of this road connects and where the sound of air flow comes from, Sato Yu has no way of knowing.

In contrast, the road on the right with blood stains as a guide seems more reliable. Although blood often means danger, it can at least prove that the last group of people who came to the air raid shelter chose this road.

In just thirty seconds, Sato Yu made a decision - he led Douzi to the road on the right.

After walking about another hundred meters, the color of the blood became brighter and brighter!

"Maybe there's more and more blood loss." Sato Yuo may have thought of this first, but after taking a few steps, he discovered a second pool of blood!

Compared to the blood stain that had been guiding him and Douzi, this pool of blood was much larger in terms of area alone.

Not only that, the shape of this pool of blood is also like a bucket of paint that has been poured on the ground, showing an extremely exaggerated spread!

According to Sato Yu's experience, this must be the amount of bleeding that would occur after someone was seriously injured in an instant.

Sure enough, when Sato Yu moved his flashlight next to the blood stain, he saw torn clothes and a few strands of hair solidified in the blood!

This also confirmed Sato Yu's conjecture that someone was indeed attacked here.

"There are no bullet casings, no sharp weapons, and no traces of fighting can be found." Sato Yuo's expression became more and more serious. He guessed that this might be a one-sided massacre, but there was not enough evidence. "Except for blood and hair, There were no corpses or organs, so there was only the smell of blood in the air but no rancid smell."

Thinking of this, Sato Yuo has lost the clue to continue the deduction.

Douzi's face was also a little pale. Although she and Sato Yuu could fly mechas to fight monsters and had seen many bloody scenes, the killing of monsters and the killing of people were completely different concepts, and she still felt an instinctive physical discomfort. .

After seeing Douzi's reaction, Sato Yuo decisively changed his position, letting Douzi stand three meters behind him, and continued to move forward in a one-to-one formation.

In the next few dozen steps, the two saw more and more blood stains, the colors became brighter and brighter, and there were even many dusty footprints on it!

clatter!

The sudden slight sound made Sato Yuu, who was walking in front, stop immediately!

Sato Yuu even kept his breathing to a minimum. While he raised his ears and waited patiently for the sound to appear again, he carefully moved the light source under the pistol to search for threats lurking in the darkness!

However, even when he scanned the tunnel from left to right with his flashlight, he didn't find anything out of the ordinary!

At least thirty seconds had passed since he heard the sound. In the dead silence, the empty and dark tunnel was as terrifying as the esophagus of a demon!

Do you want to keep walking?

Sato Yu recalled in his mind the last scene he saw before leaving the mecha. He was convinced that there were at least a dozen energy reactions in this air raid shelter!

It's obvious that he and Bean are on a dangerous path.

But precisely because monsters hunt humans, Sato Yuu is sure that the end of this road must be the sender of the distress signal!

After a brief hesitation, Sato Yuu led Douzi forward again!

Now Sato Yu feels like he is walking on thin ice every step he takes. No matter how careful he is, his combat boots will make a sound when he steps on the sand and gravel!

"One step, two steps..." Sato Yuo counted his steps in his mind, his tense index finger ready to pull the trigger at any time.

"Ten steps!"

Sato Yu suddenly stopped, his eyes fixed on the ground, and his whole body was in a tense state.

The blood trail that the two of them had been pursuing was completely interrupted here, and above the blood trail that had not completely solidified were two huge footprints that were not human at all!

Sato Yuneng felt that he seemed to be being watched by a cold gaze. He swept the tunnel with the light source again, and was shocked to find that the blood stains here covered the entire corridor!

clatter!

Until then, a familiar voice sounded in Sato Yu's ears again, and a drop of bright red blood fell in front of his feet.

The next second, Douzi's flashlight hit a deformed monster.

And this monster is hanging on top of Sato Yuu's head!
