Mu Bai walked out of the Mu family absentmindedly and unconsciously came to Tianxian Street.

It seemed that at this moment, something was suddenly missing in his heart, but he couldn't say that feeling.

"Boy, don't be in a daze, don't you just leave home, as for no? There's something good there. Gu Lao, who had ignored Mu Bai for a few days in the bracelet, suddenly spoke up.

Mu Bai's face was stunned for a moment, and his eyes gradually regained his expression and looked in the direction that Gu Lao was pointing, it was a small black stone, which looked incomplete, and the one who sold it was an old man who was about seventy or eighty years old with a face full of wrinkles carved by the years.

He asked Gu Lao softly in confusion: "Old man, is that little stone very special?"

In the bracelet, Gu Lao sighed softly, looked at the missing small stone outside the bracelet as if falling into a long memory, and slowly said after a long time: "That little stone is not something that should appear in this era..."

When Mu Bai heard this, his eyes lit up, and he ran to the old man with a smile.

He touched his chin, pretended to lower his head, looked at the items that the old man was selling, and suddenly shouted, "I want this, old man." ”

Mu Bai did not point directly to the small broken stone, but to the gorgeous robe on the side.

The old man glanced at the young man in front of him lightly, pulled out a dry hand from the robe that had not been washed for a long time, and gestured.

"Sixty dollars?"

"Six hundred, don't negotiate, take it if you want it. The old man glanced at Mu Bai casually, as if he didn't feel interesting, and closed his eyes again.

The corners of Mu Bai's mouth twitched, and he muttered in a low voice: "It's not as expensive as a torn dress." ”

He coughed and pretended to say, "Forget it, Young Master Ben doesn't want it." After a pause, his eyes turned to the small stone that was missing, and he said with interest: "That little stone looks quite interesting, how to sell it, it's too expensive, then forget it." ”

The old man's eyes opened a gap slightly, and he was still the same, and stretched out a hand.

"A hundred?"

"Hmm. ”

"Okay, deal. ”

Mu Bai hurriedly picked up the small stone on the ground, took out the storage ring given by Mu Liang, and threw a hundred yuan to the old man He didn't look back and left.

Before Mu Bai could take a few steps away, the old man sitting on the ground opened his eyes as he looked at Mu Bai's departing back, and muttered, "It's 'his' breath......"

......

It didn't take long for Mu Bai to gently pass the small stone into the bracelet, and Gu Lao in the small world of the bracelet looked at the small stone that suddenly broke into the sky, and sighed in confusion: "I didn't expect it, I didn't expect that this thing was the only thing that Lin Tianmu's kid didn't find back then, and he could actually find a small piece of it in this small place." After all, something has changed in this world..."

"Old man, old man, what's wrong with you, ask you. The outside world Mu Bai said anxiously.

"Ah, it's okay, see for yourself. Gu Lao shook his head, shook out the distracting thoughts in his mind, and passed the small stone out. "Put your blood on it. Gu Lao continued to speak.

Mu Bai didn't hesitate, he bit his finger lightly, squeezed the blood on the small stone, and something strange happened, a mysterious and weird blood-colored pattern appeared on the small stone stone, and a stream of blood-wrapped light flashed into Mu Bai's mind in an instant.

"I, I.. What is this, I'm so dizzy, it hurts... Geezer... Geezer. Mu Bai held his head and shouted in pain, and then passed out. Gu Lao looked at Mu Bai who had fallen asleep outside, his expression was not panicked, and he looked curiously at the void behind him.

This is the void emitted bursts of fluctuations, and a figure appeared, and the figure walked lightly to Mu Bai's side, frowned, and muttered suspiciously: "This kid, how do you know this thing." By chance?"

As he spoke, he released a white protective shield to protect Mu Bai's side, and his figure gradually disappeared.

Gu Lao, the bracelet leader, witnessed all this happening, as if he knew, and there was no surprise on his face.

In fact, he did know that Xia Yang protected Mu Bai all the way, since the black wind that abducted Mu Bai last time, Gu Lao recognized Xia Yang, but he didn't want Xia Yang to know about his existence now, so he had been deliberately avoiding Xia Yang.

I don't know how long it took, Mu Bai's fingers moved slightly, his eyes slowly opened, he rubbed his head and sat up, and suddenly there were some memories in his mind that didn't belong to him.

"Boy, keep your heart, don't think about it. Old Gu's energetic voice suddenly appeared in Mu Bai's mind.

Mu Bai looked at the blood-colored characters in the distance, exhaled a deep breath of turbidity, and approached the blood-colored characters again, this time, those blood-colored characters did not repel him, but floated around on his body, as if he had determined his identity.

Before Mu Bai could react, a smell of blood came to his nose, and he stared blankly at the mountain of corpses and bones in front of him, with blood everywhere and stumps and broken arms everywhere.

"Gross. Mu Bai suddenly vomited with a pale face, since he was a child, he had never killed anyone, let alone the amazing bloody scene in front of him.

And on the sky of the bloody corpse mountain, two blood-colored characters suddenly appeared: "Book of Killing". Rows of dense small characters also appeared below, "The sage said, with compassion as his heart, but when the sage is angry, he is a corpse lying thousands of miles, if he wants to survive in the cultivation realm, he must master one of the ways of 'killing', kill, kill the innocent, kill, only kill those who should be killed, kill, kill yourself."

Mu looked at the blood-colored characters in front of him stupidly, and then this scene quickly disappeared.

He eased up and asked Gu Lao hesitantly: "Old man, what is that, and what is the reason for killing yourself recorded in it." ”

Gu Lao in the bracelet thought for a moment, and after a while, his eyes became clearer, and he said: "That is one of the six heavenly books between heaven and earth, the Book of Killing, and the killing of oneself recorded in it is not really killing oneself, but killing oneself." ”

“......”

"Comprehend it for yourself. Gu Lao looked at Mu Bai, who was rolling his eyes, and said awkwardly touching his long white beard.
