If Mu Yu was allowed to bully the gray disciple by himself, he would naturally not do it, and he would not be happy in his heart. If you do it too falsely, it is estimated that the other party will not be fooled. Therefore, he planned to secretly pay attention to those cultivators who specifically bullied the gray disciples, so that it would be more realistic.

Although most cultivators look down on gray disciples, not everyone will intentionally make things difficult for them, and some cultivators are quite friendly to gray disciples.

However, it is the minority who are friendly, and the majority of the gray disciples do not embarrass them, and the rest are those who have nothing to do to bully the gray disciples, which is also Mu Yu's goal.

Mu Yu spent the whole day observing at the door of the Gray Disciple's Courtyard, seeing that those cultivators would deliberately trouble the Gray Disciples. The gray disciple's daily work in the academy is probably to clean up, serve tea and pour water, and meet the various needs of past cultivators.

From time to time, a cultivator would come to the Gray Disciple's Courtyard and ask them to come over to do something, most of them had a cold expression, and left after telling the Gray Disciple what to do, with a proud expression, as if they didn't want to say more, but they didn't embarrass the Gray Disciple.

Mu Yu waited for a long time, and finally waited for someone to find fault.

It was a middle-aged man who was flying and domineering, his cultivation was not high, but his tone was arrogant, his face was sallow, he looked malnourished, and he didn't know what sect he came from. At this moment, he was teaching a gray disciple in his twenties, and the gray disciple's face was flushed, and he was obviously scolded very aggrieved.

"Young Master Fang, the bone grass you asked me to buy is gone, and I ran all over that market and didn't find it!" the gray disciple whispered, he felt so aggrieved that he was about to cry.

Fang Gongzi said angrily: "There is no Fang Market in Qingshou City, you won't go to the Fang Market in Yicheng to have a look? I really don't understand what each sect does by handing over spirit stones every year to feed you disciples, and you can't even do this little thing, waste!"

"Yicheng's Fang Market is on the mountain, and it's so far away from here, I'm just practicing Qi and cultivating a heavy heaven, and I haven't learned to fly yet, it will take five or six days to go back and forth!" the gray disciple's voice was crying.

"Don't give me nonsense, I'll only wait in the academy for three days, if you don't buy the bone grass I want within three days, I'll break your legs! There are so many gray disciples in the academy, not one of you is missing!" Fang Gongzi's momentum during the foundation building period was all pressed on the gray disciple, and the gray disciple retreated to the wall with a pale face, looking at Fang Gongzi in horror, his mouth was already so frightened that he couldn't speak.

Mu Yu frowned and looked at this Fang Gongzi, he had the cultivation of the foundation building period, if he went to Yicheng in person, it would actually be a very quick thing, but he had to summon such a gray disciple. It was impossible for that gray disciple who had cultivated Qi to complete this matter in three days, and he would definitely be punished at that time.

He also knew that this kind of plant had an excellent healing effect, and it was relatively rare, and it generally grew on the bones of demon beasts above the third order. The living area of the third-order demon beast in the demon beast forest was something that ordinary cultivators would not dare to set foot in easily, which also led to the scarcity of bone grass. Even if that gray disciple ran to Yicheng, I am afraid that he may not be able to buy it.

Fang Gongzi left, but the gray disciple didn't have any relaxed look, he looked at Fang Gongzi's back in a daze, and there was a trace of helplessness in his eyes. Those who serve these cultivators have to be afraid all day long, and they will be beaten and scolded if they don't go wrong.

He also envied the kind of cultivator who cultivated to a high level, able to fly with a sword and cast spells. At the age of sixteen, he stayed with hope, hoping to be lucky enough to worship a certain master, but unfortunately it backfired, and no one took a fancy to his unbearable cultivation talent. It's too late to regret it now. Deacon Xun said that when you choose to stay, there are only two ways to leave the school, one is to be favored by a certain sect and become a disciple of the sect, and the other is to die.

The gray disciple shook his head, and reluctantly turned around and entered the courtyard, he was going to pack up his things and see if he could get this thing done in three days.

"This Fang Gongzi really deserves to die. ”

Mu Yu muttered in his heart, but after thinking about it, there are more people like Fang Gongzi in the cultivation realm, and those with high cultivation look down on those with low cultivation, should everyone with high cultivation deserve to die?

Mu Yu didn't know how to judge a person for a damn reason, and he didn't think too much about it, so he followed this Fang Gongzi.

This Fang Gongzi's name is Fang Chang, and he is a disciple of the Xuanbing Sect, and the strength of the Xuanbing Sect is considered to be on the upper side, so the talent of the disciples of their sect is also better. Mu Yu followed Fang Chang to the Xuanbing Sect's courtyard, but unfortunately he couldn't enter the courtyard, there were no trees in this courtyard to enter, which made Mu Yu a little helpless, so he could only stay in the trees outside.

Night fell, Mu Yu waited outside the Xuanbing Sect Courtyard for a day, not knowing if that black shadow would come to trouble this Fang Chang at night. He wasn't really sure, because at the end of this day, there might be other cultivators who were bullying the gray disciples, not just Fang Chang, who knew if the black shadow would attack the other party?

Mu Yu found a tall tree and was able to see the situation inside the Xuanbing Sect. The light in Fang Chang's room was still on at the moment, and Mu Yu's eyes were always staring at his room. Just when Mu Yu was about to give up, the light in Fang Chang's room suddenly went out.

Mu Yu's heart tightened, and he didn't know what it meant when the lights went out, maybe if he just wanted to go to bed. But at this moment, the door of Fang Chang's room was silently opened, and a shadow flashed out, seemingly holding another person in his hand, and quickly rushed into the darkness of the courtyard, and then disappeared.

Mu Yu's eyes widened, he wanted to see what was going on. It's just that each sect has its own courtyard formation, if he breaks in, he will definitely touch that formation, and if Fang Chang has an accident and he is seen on the spot, it won't be clean.

He had no choice but to wait until the next day, and went to the Xuanbing Sect to inquire about Fang Chang's news, and sure enough, he heard from the Xuanbing Sect that Fang Chang seemed to have left the academy last night.

But this was impossible, Mu Yu stayed outside all night and didn't see anyone coming out of the Xuanbing faction's courtyard.

"Could it really be that someone is venting their anger for the gray disciple?"

Mu Yu thought in his heart, he was also present on the night when Xiaohu was killed last time, and when he went to chase the black shadow, he just disappeared when he chased it to the yard, and this time too, isn't there a secret passage in every courtyard?

Mu Yu was still a little slugging at this idea, if that person dug a secret passage in the courtyard of each sect of the academy and was not discovered, it was impossible. The project of digging a secret path is huge, and the schools are all cultivators, so it is too difficult to hide from the cultivators.

However, Mu Yu returned to his courtyard and began to search carefully.

The courtyard of the Falling Dust Sect was very small, and it didn't take long for Mu Yu to search his yard and not find anything abnormal. The only way to the outside world is probably a drainage channel, but that drainage channel is very narrow, only wide enough for a person's head, and the body and shoulders cannot pass.

Mu Yu still didn't believe in evil, he controlled a tenacious root grass, let its roots slowly seep into this drainage channel, this did not matter, he was surprised to find that the bottom of this drainage channel was so wide! It was completely possible for two people to pass through at the same time.

This means that if the black shadow really relies on the drainage channel to enter and exit the various courtyards, the size of the entrance to the drainage channel does not matter, as long as the piece of land is cut. Entering the drain and covering the land is not visible from the outside without careful attention.

The land of Mu Yu's annex had not been cut, and it was clear that the black shadow had not come to visit.

Mu Yu landed in the drainage channel by the root of the grass, which was only used to allow rainwater to flow out, and it was supposed that it didn't need to be so large. Mu Yu stood in the gloomy drain, the light of the Shadow Splitting Sword illuminating the road ahead, and a putrid smell hit him, making him frown.

He walked a few meters along the drain and found an uneven passage next to it, which was strewn with dirt and some strange claw marks on the walls of the passage, as if some animal had dug it out.

Claw marks!

Mu Yu thought of the claw marks on the necks of the disciples of the Qingsong Sect and the Jiuhua Sect, as well as the missing hearts, which were the only ones that could create that kind of wound. Mu Yu turned into this passage, the dirt of the passage was very wet, he had just taken a few steps, and with a chirp, he stepped on something.

Looking at it through the blue light, it was the bones of a mouse, the mouse was not completely rotten, Mu Yu just stepped on its head, stepping on its brain, which made him look very uncomfortable, and hurriedly continued to walk forward. The passage was straight, and after walking for a while, he returned to the drain.

Mu Yu saw a bright light in front of him, and he walked over and looked up to see that this should be the drainage outlet of another courtyard. He didn't know what the point of these uneven passages was, and he continued to walk down the drain.

It's so quiet that the only occasional dripping sound echoes through the drain is scary.

Mu Yu didn't know where he had gone, and every time there was a bright light, he had to go over and take a look, and lift it with his hand to see if he could lift the ground around the drain, but he didn't succeed several times. After walking for about half an hour, a thick rancid smell came to my nose.

The rancid smell came so suddenly that Mu Yu almost vomited all the overnight meal. The rancid smell seems to be mixed with a heavy smell of blood, which is disgusting.

He settled down and turned into a passageway. There was a sound from the front, like something grinding its teeth, accompanied by a creaking sound.

"Don't scare me!"

Mu Yu despised himself a little, how could he say that he was also a cultivator, and he was actually afraid of this kind of thing. He waved the Shadow Sword forward, and as soon as the blue light of the Shadow Sword fell, Mu Yu suddenly saw a pair of big swollen and white eyes, and stared at him in a daze.

It's the human eye!

"it!"

Mu Yu jumped to his feet and hit his head on the top of the passage, and he screamed in pain, feeling his cold hairs stand on end.
