After about a quarter of an hour, the three of them came to the banana tree in front of Aunt Zhao's house and stopped to watch.

It is a two-meter-tall plantain tree that stands out from the crowd in front of the gate, but it is gray and the rest of the vegetation is green.

On closer inspection, the branches and leaves of the plantain tree have withered and rolled up, the branches and leaves that used to be the size of a palm are now only the size of a little finger, and they look very strange, the gray color looks unusually depressed, there is no green vitality that any vegetation should have, the wizened branches are still holding on to death, the weight of the whole plantain, the plantain that fell on the ground is black, as if it has been roasted by charcoal, emitting a foul pungent smell.

"Shangguan Daxian, what can you see?" Aunt Zhao asked respectfully, for fear of offending Shangguan Yunyun, her son Zhao Daniu's life can be completely controlled by Shangguan Yunyun's "hands"!

Shangguan Yunyun didn't answer her words, but looked at Xiuxiu, she opened her mouth and said, "Xiuxiu, what do you see?" ”

Xiuxiu gently touched Qiong's nose, her black eyes swaying from side to side, but she never took her eyes off the banana tree.

After observing for a while, she expressed her opinion: "This banana tree was originally alive, but now it is like it has been burned, but looking at the signs of its injury, it does not look like a fire!" ”

"Not by fire?" Aunt Zhao's face was full of confusion, and she asked loudly, the banana tree was scorched, and the pungent smell of burnt next to the tree was obviously burned by fire, what Xiuxiu said now, how could she not understand a word, it was burned by fire, and it was not burned by fire, she was all wrapped in, and she couldn't tell whether the banana tree had been burned by fire.

"Xiuxiu, you go on," Shangguan Yunyun nodded appreciatively.

"If it was burned by fire, then this fire must not be an ordinary fire, otherwise the plantain tree would not have been burned like this," Xiuxiu continued to explain, the outside of the banana tree that had been burned by ordinary fire, the branches and trunks would be very black, as black as carbon, not this strange gray, and if the plantain tree was burned to this extent, it would definitely not stand upright again, but would break or pull and hang on to the ground.

Shangguan Yunyun couldn't help but smile, for Xiuxiu, she liked it more and more, not only is she well-behaved and sensible, but she is also very thoughtful, she is very attentive to everything, and she is also very "on the road", her analysis is indeed right, this banana tree is indeed not burned by ordinary fire.

"Anthracene, you say come and listen!" Shangguan Yunyun decided to put Xiuxiu to a live test, if she can pass this level, then she can be out of the school, you know, Zhao Daniu suddenly disappeared, there is a great mystery hidden in this, even Shangguan Yunyun Until now, according to Aunt Zhao's description, combined with the scorched banana tree at the scene, coupled with her own experience, she deduced seven or eight layers, and she is not completely sure. If Xiuxiu can really see through the mystery of the scorched banana tree, in the future, Qin Lingxuan can rest assured that she will be entrusted to take care of her, and Shangguan Yunyun will not have to worry about it anymore.

Xiuxiu knew that there were not many opportunities like this, and she cherished it because she knew that there was not much time left for her.

"Miss Xiuxiu, if you need help, just ask, but if there is anything in the family, I will never be stingy...... Aunt Zhao firmly stated her position and attitude, but her face was full of concern and love for Zhao Daniu, Zhao Daniu has reached the age of starting a family, and the incense of the Zhao family is about to start from him, she doesn't want Zhao Daniu to have an accident, and she doesn't dare to imagine that the incense of the Zhao family is broken like this.

Xiuxiu walked into the banana tree, took out a delicate white square handkerchief, and gently wiped the branches of the banana tree, the white handkerchief immediately showed gray, and the gray ashes were also mixed with some red powder particles, if it weren't for her sharp eyes, she wouldn't have found these fine red particles, because they were too small, so small that people couldn't tell them.

"Master, I'm sure the banana tree wasn't burned by fire," Xiuxiu said categorically, then handed the white handkerchief to Shangguan Yunyun.

"The gray ashes are entrained with red particles, which does not directly prove that the banana tree was not burned by fire, these red particles cannot be explained for the time being, but these ashes are the color that they should have after being burned by the fire," Shangguan Yunyun retorted, in fact, she knew it well, and she just deliberately put pressure on Xiuxiu to see how she responded.

Aunt Zhao was confused by the master and apprentice, one said that she had been burned by fire, and the other said that she could not prove that she had been burned by fire.

"Master, look!"

Xiuxiu took out a black dagger, although the color seemed to be rusty, but the dagger blade flashed with cold, making people shudder, and it was enough to see that it was extremely sharp, and the handle of the dagger was carved with seven stars, bright and lifelike.

This is the seven-star dagger, it is Shangguan Yunyun's beloved thing, a year ago, after she entrusted Qin Lingxuan to Xiuxiu, she taught this seven-star dagger to Xiuxiu, hoping that she can use it one day, the seven-star dagger is not an ordinary cold weapon, but can drive away ghosts and demons, because this is a dagger made of thousands of years of cold iron to refine the essence, and then after hundreds of precision processing, to create a dagger, the most important thing is that this seven-star dagger is injected with the inscription spell of exorcism and demon expulsion, so the power is amazing.

When Shangguan Yunyun was practicing in Huoyun Cave, when she received the seven-star dagger handed down by her master, the master said this to her, and told her that the seven-star dagger should not be used casually, and should not be used unless necessary, because every time it is used, the inscription and spell in the seven-star dagger will be less, for so long, Shangguan Yunyun has not used it, just because this is the treasure that the master passed to her before his death, this is a sustenance of love, and it is the best thing for her to have a close connection with the master, whenever she sees it, She thought of her master, and remembered the years of joy and sorrow in the Huoyun Cave.

Now that Xiuxiu has decided to use it, Shangguan Yunyun will not stop her, so she should let her "test the water"!

After getting Shangguan Yunyun's affirmation, Xiuxiu stabbed the seven-star dagger slightly into the branch of the banana tree, without any effort at all, the seven-star dagger pierced deeply into the banana tree, a finger deep, and she lifted the seven-star dagger up a little harder, and the branch of the banana tree was cut a gap.

"Master, look," Xiuxiu continued to Shangguan Yunyun affirmatively after cutting the branches of the banana tree, "The burned banana tree should not be this color, it should be charred on the outside and tender on the inside, that is, black on the outside, and green and white on the inside, and the current banana tree is very abnormal, the outside is gray, and the inside is also gray, it seems that the whole body of the banana tree is gray!" ”

"Yes Xiuxiu, then what conclusions did you come to yet?"

"Plantain trees are not destroyed by fire, but necrotic!" Xiuxiu said heavily, it was the first time she had seen that the vegetation was actually necrotic, this necrosis was not caused by natural disasters, etc., not man-made, but was "infiltrated" and destroyed by some mysterious force, destroyed from the inside out, and she told Shangguan Yunyun her conjecture.

Xiuxiu's guess exceeded Shangguan Yunyun's expectations, she didn't expect that Xiuxiu would be so cautious in her observation, and she could speculate on the mysterious power based on this, it seems that she can indeed let go and let Xiuxiu "fly".

"What? Necrotic? Mystical powers? Aunt Zhao's tone became hurried, her face was full of panic, although after she saw the banana tree, she knew that all this was not simple, and even very bizarre, so she hurriedly went to lock the door of Guan Yunyun's house, but she never imagined that the banana tree was invaded by a mysterious force and finally died from the inside out.

"Yes, this mysterious power is a gray energy!" Xiuxiu answered Aunt Zhao's question, and at the same time revealed the essence of the mysterious power.

"What is grey energy?" Aunt Zhao forced herself to stay calm, her hands turned into fists, and her nails, which had been dulled by long-term farm work, were deeply sunk into the flesh of her palms, and a trace of blood flowed out, but she didn't feel this pain in the flesh.

Shangguan Yunyun did not continue to ask questions, but stood quietly, her face was full of kindness and kindness, and she praised Xiuxiu in her heart.

"Gray energy is the energy of ghosts," Xiuxiu continued to explain, the world of ghosts has no color, only monotonous and cold gray, lifeless gray, full of destruction gray, and the energy released by ghosts is gray energy, relying on this energy, stimulating people's cerebral cortex, distorting people's magnetic field, and making people have illusions, in fact, it is not people who have illusions, but ghosts inject gray energy into people's brains, confusing nerves, and transferring people's thinking to their dimensions. Because people and ghosts are in different dimensions, they usually do not affect each other, and they live in their respective dimensions, and once people enter the dimension of ghosts, their emotions and perceptions also enter their gray world, and they inevitably accept their persecution, so ghost killing is done in their dimensions, although people die in their dimensions, but they still create the illusion of death in the human dimension.

"Ghosts? Ghost ......" Aunt Zhao couldn't control her emotions anymore, her body was weak, she sat on the ground with her buttocks, and muttered to herself, "Ghost, ghost, it's really a ghost......"

"Don't panic, calm down!" Xiuxiu opened her mouth to comfort, although the ghost thing is an indispensable topic for ordinary people, everyone will talk about it, and they will share their own experiences about ghosts, most of them are hearsay, but the ghost thing really happened to them, no normal person can stay calm, this is a very normal phenomenon, this is like a bunch of people watching monkeys are chained by their necks and performing in cages, everyone looks at it with relish, laughing and falling back, they are always just a spectator of the fun, But when you are chained by the neck and put in a cage for a "pleasing people" performance, you will panic and be frightened.

Aunt Zhao didn't seem to be able to hear Xiuxiu's persuasion, her mouth was still gossiping, she kept muttering, her body trembled, and she couldn't calm herself down.

"Don't want to save Zhao Daniu?" Shangguan Yunyun suddenly said coldly.

"Big Bull?" After hearing Zhao Daniu's name, Aunt Zhao's eyes regained a trace of clarity, and then, tremblingly, she got up from the ground, half-kneeling and begging, "Please, save him!" ”

"It may not be saved!" Shangguan Yunyun's words made Aunt Zhao fall into despair again.

Xiuxiu also fell into contemplation along with this sentence: the suddenly disappeared Zhao Daniu, the necrotic banana tree, the mysterious ghost energy, what is this ghost? It's so destructive......
