Red, still red.

Blood red.

The whole world seemed to be soaked in blood, exuding a strong bloody smell. His vision was very blurry, like a nearsighted person taking off their glasses.

He didn't know where this was, and he had never been to such a place before.

Anxiety was brewing. This had nothing to do with ability, but was more like a survival instinct. His subconscious told him that this place was dangerous, extremely dangerous.

He tried to take a step forward. The sensation under his feet made his heart tighten. The soil under his feet seemed to be soaked in blood, and there was a sticky texture when stepping on it.

Like a swamp that could swallow people.

He activated his ability. What he saw now was the scene that happened before No. 10 died, but not all of it. He could only see a part of it at the time, or even just sporadic fragments.

Now No. 13 could only confirm two things.

First, he had never been here before.

Second, a very tragic battle seemed to have taken place here.

He gritted his teeth and trudged forward step by step. He hadn't seen any useful information yet, not even No. 10. He was unwilling to give up like this.

Moreover, he only had this one chance. Such spying could only be used once on the same person.

As time passed, the enormous pressure gradually made him unable to think, and his vision gradually darkened. He knew that he was approaching his limit. Suddenly, the blood mist in front of him dispersed a little, and the scene revealed made his pupils tremble.

Found it!

He saw a figure with his back to him, kneeling on one knee, his body much stronger than ordinary people. Just looking at his back gave him a long-lost sense of security.

It was No. 10, no mistake!

But before he could get closer to see clearly, the next second, No. 10's body trembled, and then the tip of a knife pierced out from No. 10's back, and a large amount of blood gushed out in an instant.

"No!" No. 13's eyes were bloodshot. At this moment, he had forgotten that he was just a passerby in this world, unable and powerless to change all of this.

No. 10's body trembled for a moment, then crashed to the ground.

He was dead.

Really dead.

No. 13 could be sure.

The intense stimulation of the scene instantly overwhelmed No. 13's psychological defenses. He had overestimated himself after all. The next second, he lost consciousness. In the last moment before losing consciousness, he vaguely saw a blurry black figure kneeling down in front of No. 10's corpse.

Very similar to No. 10's previous movements.

…

"Hoo—"

"Hoo—"

A black car was parked on the side of the road, perfectly integrated into the night, inconspicuous.

Inside the car, there was a constant echo of muffled breathing.

The breathing became more and more rapid, making people uneasy.

Until… the boy lying across the back seat suddenly opened his eyes.

"Hoo—"

"Hoo—"

The boy was covered in sweat, and his slightly contracted pupils were full of anxiety. Before he could speak, a low voice came from the driver's seat, "You're awake. How do you feel?"

No. 2 had been guarding him for a long time. Just now in the studio, No. 13 held No. 10's hand, and in just a few seconds, he actually fainted directly, his face flushed badly, as if he had overused his brain.

He knew that No. 13 must have seen something very important.

"No. 10… Where are they?" No. 13 raised his head and asked in a hoarse voice that didn't belong to his age. His memory was still in the studio, and there was a gap in his memory.

"Seeing you fainted, I found an excuse to take you away." No. 2 turned his head, staring at No. 13's face through the rearview mirror, his eyes full of worry. "Tell me, what did you see?"

"I saw… saw the guy who killed No. 10." No. 13's voice was trembling.

No. 2's fingers gripping the cowboy hat suddenly clenched, "Who is it?!"

"I didn't see his face clearly, but I'm sure this person is not one of the Night Watchers. It's someone we know, right here with us!" No. 13's face was extremely pale. "His figure felt very familiar to me."

No. 2 was much calmer than No. 13, signaling No. 13 not to panic and to speak slowly. "You saw the scene where No. 10 was killed?" No. 2 asked in a low voice.

"I saw it."

"Location?"

No. 13 shook his head. "I don't know. It looked like there had been a great battle. Everything was destroyed. The whole world was blood red, and the ground underfoot was soaked in blood."

"Our world wouldn't have such a place. It should be in a mission world." No. 2 analyzed calmly. "The mission that could kill No. 10 is definitely within the Old Chairman's domain, that bus!"

"You mean… in one of their next missions?" No. 13 seemed to understand something, nodding. "What you said makes sense. That line of thinking is right."

No. 2 pondered for a moment and continued, "What else did you see? How was No. 10 killed? Do you remember?"

"A knife. He was stabbed in the heart with a knife. The blade pierced through his body and came out from his back, a fatal blow." Recalling the scene at that time, No. 13 couldn't help but shudder, as if it was he, not No. 10, who had been killed.

"A knife…" No. 2 fell into deep thought. There were too many people around them who used knives. No. 1, No. 6 were among the experts, and even No. 8 was very skilled at playing with knives.

There was also Wu, who was guarding Zero and No. 10. His knife was impressive.

Moreover, although No. 10 was killed by a knife, this did not mean that the murderer was necessarily good at using knives, or that the knife might have been picked up. In short, such clues were too thin.

"What kind of knife? A long knife, a short knife, a curved knife, or something like a dagger?" No. 2 was trying to narrow the range of suspects.

But this time, No. 13 shook his head, revealing a painful expression. "I don't know. I didn't see clearly. I passed out as soon as No. 10 fell."

As soon as he finished speaking, No. 13 took a deep breath. When he raised his head again, his whole feeling had changed. No. 2 immediately frowned. He seemed to know what this child-like guy was going to do.

"Don't do this. Let's think of other ways." No. 2 turned around, grabbed No. 13's arm, and a rare look of anxiety appeared on his face.

No. 13 smiled and gently patted No. 2's arm. Seeing that he had no intention of letting go, he couldn't help but sigh, "No. 2, I know you're doing this for my own good, but now… there's no time."

"No. 10 has done so much for us. Now that he's in trouble, it's our turn to help him."

"And you don't have to worry too much about me. I have a big life, and I won't die. Maybe I'll be lucky and verify the murderer the first time. What do you say?" No. 13 grinned, looking very optimistic.

Since he had already said this, No. 2 also understood No. 13's determination. His fingers trembled a few times, and finally he let go. "Be careful. I'll stay here and won't go anywhere."
