Mother Liu in the back obviously knew something, Qin Mu looked at Mother Liu, the fat guy twisted his waist, and then he came over and said with a speechless face: "Qin Mu, there is something I didn't tell you." ”

"What?"

"This ......" Mother Liu glanced at Hu Ling, and did not speak directly, but said to Hu Ling with a vigilant face: "You really have to believe that he really has no intention of harming you, a person who doesn't even know common sense, let alone wants to harm others." ”

"Common sense?" Qin Mu repeated, with a puzzled expression.

Mother Liu leaned closer and said, "Do you know what is the most precious thing about the people of Tushan?" Do you know why they can't be killed? Even if the Nine Tails are broken? ”

"Because...... Is it a youkai? Qin Mu glanced at Hu Ling hesitantly, and blurted out, Hu Ling sat on the ground and rolled his eyes.

She was already eighty percent sure that it was not the person in front of her who attacked her in the alley at that time, although the one in front of her was very similar to that person, but there was a difference in temperament, and because of the weather, it was not easy to see a fast-moving martial arts master clearly.

And when she pounced on Qin Mu just now, Qin Mu used most of the tricks in the psychic world, and his hand-to-hand combat ability was almost zero.

"Youkai your sister, there are so many monsters around you, you sue me, is there any monster that can't be killed?" Mother Liu said helplessly.

"That's why."

"Because they have a second heart." Mother Liu glanced at Hu Ling and said.

And Hu Ling's vigilance against Liu's mother immediately soared several levels, and the eyes looking at Liu's mother were also a little strange.

Mother Liu hurriedly waved her hand and said, "I'm a member of the Psychic Association, so I'm not so painful." ”

Hu Ling just nodded, but the vigilance in his eyes still did not decrease.

"The second heart?" Qin Mu glanced at Hu Ling, very curious, such a small person, where does the second heart grow?

"Yes, when they die, the second heart recharges to replace the first heart." Mother Liu said: "This is why they can survive after they have no nine tails." ”

"But there are only two lives." Qin Mu probably understood what Mother Liu meant, and felt that it didn't seem to be a big deal.

"Who said there are only two lives?" Liu Ma said speechlessly: "Although the second heart replaces the work of the first heart, but at the same time it will repair the first heart, and when the first heart is completely restored to normal, the second heart will fall asleep again," Liu Ma explained: "In this case, unless both hearts are at the end of their rope, they are immortal, so their lifespans are very long." ”

"We won't die at all, the second heart is condensed by our cultivation." Hu Ling rolled his eyes and said.

Mother Liu glanced at her with an embarrassed face, and said with a smile: "Yes, yes...... Of course you won't die. ”

Hu Ling rolled his eyes angrily and said, "Of course, unless you cultivate to a certain level, you will die." ”

"Is it okay to think that when their second heart works in place of the first, it's the best time to kill?" Qin Mu frowned and thought for a moment, and hurriedly said.

There was silence in the whole room, and after a long while, Mother Liu gave Qin Mu a thumbs up, and then said: "You don't know, the speed at which this second heart completely repairs the first heart is related to age, the older you are, the slower the repair speed, like her age, it can be done almost instantly." ”

Qin Mu glanced at Hu Ling, nodded, and said, "That seems to be good, but this is just a secret method for others, you said before that the fox of Tushan has a very precious thing, what is it?" ”

"It's the second heart." Mother Liu said honestly, while Hu Ling looked at the two of them with a wary expression.

"A second heart?" Qin Mu glanced at Hu Ling and said; "You mean, when the Nine-Tails are broken, take out their second heart, and they'll hang up?"

"Yes, because there is a long time between fake death and resurrection, but when taking the second heart, you must be careful, it seems that you must also use some kind of local special anesthetic, so that they can always keep their souls asleep before they can do it, otherwise, anything can become an opportunity for the second heart to start. It's like just now. Mother Liu hurriedly said.

Qin Mu glanced at Mother Liu, and said speechlessly: "Is there nothing to find in the psychic world, even a heart is regarded as a treasure, this thing can't be made of gold?" ”

As soon as Qin Mu said this, not only Mother Liu, but even Hu Ling looked at him with disgust.

"What, I'm wrong?" Qin Mu's face was inexplicable.

"Ahem...... "Ahem" Mother Liu was frightened by Qin Mu's thinking pattern: "This thing is much more valuable than gold, and the second heart, in a person's body, can also be used." ”

"Can it be used too?" Hua Wuyue, who had been silent, asked rhetorically: "Then isn't it immortal to put it on?" ”

"That's not it, it's just a few more lives, of course, it depends on the cultivation of the owner of that heart, the higher the cultivation, the more life it carries, because the second heart will repair the first heart when it is activated, for Tu Shan's people, the cultivation is gone, and they can be cultivated again, but for people, the cultivation in the second heart is gone, then it is really gone." Liu Ma explained this, and everyone could understand it.

"How many people know about this kind of thing?" Qin Mu asked with a heavy face.

"There are a lot of people who know, but there are not many, and only a few big sects and families know about this kind of thing, but you know, it's not the same thing as really robbing it, Tushan's people are so protective of their shortcomings, who has the courage to ......" Liu Ma sighed and said, but looked at a few corpses in the distance and said, "But now I also have the courage to do so." ”

Hu Ling only noticed the four corpses displayed on the side at this time, and was stunned, his face gloomy: "They are my people." ”

"What are you Tushan people doing in Ningcheng?" Qin Mu said speechlessly: "I remember that Tu Shan is quite far away from this place. ”

"It's none of your business." Hu Ling obviously didn't want to continue to talk about this matter, and hurriedly said.

"It seems that the person who killed Tu Shan was either their enemy or came for the second heart, but I think it seems that they are coming for you, Brother Qin." Mother Liu said with a smile, and finally her eyes fell on Qin Mu's body with a smile on her face.

Qin Mu was stunned, and said a little speechlessly: "What does it have to do with me, isn't this Tu Shan's own business?" ”

"All the evidence points to you." Liu Ma said with a smile, he walked quickly to one of the four corpses, and grabbed a strange machine next to him, which looked a bit like a barcode scanning thing in the supermarket.

He took the object and swept it over the corpse, only to see pale blue marks appear on the corpse in many places, like a splashed ink painting.

Qin Mu didn't know why, but Liu Ma said: "This is the new product of the Psychic Association, you look at the marks on the corpse, these are all traces left by mana, and most of the marks on the corpse are concentrated in the ears, indicating that it is a sound attack, and it is near your home, and it is a sound attack, so who the murderer is, it has been revealed." ”

Qin Mu was stunned, and then there was anger on his face.
