Gu Chuqing was slightly surprised and didn't understand Mu Tongguang's intention.

She thought about it for a moment, raised her eyes to Hei Wuchang and asked, "Are there any other clues? Did something like this happen elsewhere tonight?"

"Nothing."

Hei Wuchang shook his head and then said: "The strange changes in ghosts here should have started a month ago. According to my records in the underworld, there are no missing ghosts in other places except here."

In a few words, Hei Wuchang explained the causes and consequences of his appearance here.

Gu Chuqing lowered her head and thought, and after a moment, she said crisply: "Is there a time limit?"

Since the ancestor called to take over, there must be a purpose.

However, she is a student now and does not have much free time. Although it is winter vacation now, she does not have nothing to do during this winter vacation. They still need to recover Gu Yao's body and those who came to the market to target the ancestor.

.

If there were enemies of the Gu family among those who came here, she would be even busier and would not have time to investigate the matter entrusted by Hei Wuchang.

Hei Wuchang: "Nothing."

Hearing this, Gu Chuqing raised her brows and said, "Okay, I'll investigate when I have time."

"This is the soul-inducing incense. If you find any clues, you can light the incense and call me up." Hei Wuchang waved his hand and threw a piece of dark incense into Gu Chuqing's arms.

Gu Chuqing nodded, indicating that she understood.

Hei Wucang nodded at her, and did not intend to stay for long. He suddenly flashed and disappeared from the place.

When he came, he saw a ghost on the mountain. It seemed that the ghost had not entered the underworld yet, so he had to go and take him back to the underworld.

Hei Wuchang left, Gu Chuqing put the soul-inducing incense into her pocket, walked up to Mu Tongguang.

"Why did ancestor let me take over the mission from the underworld?" Gu Chuqing asked in confusion.

Mu Tongguang said in a deep voice: "I have been involved in what Hei Wuchang said. The reason why the Gu family got involved in this matter back then was because it was related to the Zhuyou clan."

That incident happened two hundred years ago. It was a big deal. At that time, Black and White Wuchang personally visited the Gu family and asked the Gu family for help. And the matter was also very difficult. In the end, all the zombie ancestors of the Gu family were even dispatched.

In that incident, the Gu family discovered traces of Zhu Youshu, and it was then that they began to suspect that the other Zhu You families were not as declining as they thought.

It was also because of this that when he was looking for the mastermind behind the scheme against the Gu family, he immediately cast his doubtful eyes on several other Zhu Youshu families.

Gu Chuqing's dark eyes paused and she said solemnly: "The Zhuyou clan?"

Mu Tongguang nodded: "The Gu family is not the only Zhu Youshu family in the world. Besides the Gu family, there are three other families. However, those three families fell into decline a few years ago. In the end, only

The ancient family still inherits it.”

"My Gu family has also declined in the eyes of others, but Gu Yao and I are still alive and kicking, and we have even inherited the skills of our ancestors." Gu Chuqing raised her eyebrows and shrugged: "It is said that it has declined, but it is only speculation by outsiders."

Mu Tongguang smiled happily: "Indeed, everything is just our guess."

Guchu Qingxing's eyes brightened slightly: "Ancestor, tell me what happened back then."

Mu Tongguang: "The cause of the incident is in the underworld. We don't know what caused it. We only know that a large number of resentful spirits escaped from the underworld, and for some unknown reason, these resentful spirits were transformed into walking corpses."

Gu Chuqing was horrified: "Walking corpse?"

Mu Tongguang nodded: "He is not afraid of the sun, has great strength, and likes raw meat."

Gu Chuqing: "Isn't that the zombie on TV?"

Mu Tongguang: "The biggest difference between the walking dead and zombies is that their corpse poison does not have the ability to infect. Although it is powerful, it is easy to destroy. Even ordinary mortal weapons can destroy it."

Gu Chuqing: "What happened next? If it's so easy to kill, then why did Black and White Wuchang come to our Gu family?"

Mu Tongguang: "Because, those walking corpses are made by the resentful spirits and are not naturally formed. The resentful spirits have been infected by the corpse control technique in Zhu Youshu. Before killing them, you must know the corpse control technique, otherwise you will kill them."

Immortal."

Gu Chuqing lowered her head and took out the Yin Yan Stone from her pocket: "Does Hei Wuchang suspect that this stone was left in the Yang world two hundred years ago?"

Mu Tongguang nodded: "Maybe. Moreover, he should have noticed that I have also been affected by the corpse control technique."

Gu Chuqing was shocked: "What, corpse control technique?"

Although Gu Chuqing knew that Mu Tongguang had been tampered with, he never thought that it was a corpse control technique?

According to the ancestral records of the Gu family, a corpse controlled by the corpse technique is almost the same as a puppet, and every move is controlled by the person behind it.

But Patriarch Mu's current situation does not look like he has been controlled by the Corpse Control Technique.

Mu Tongguang nodded: "Well, when I just woke up from the northwest desert, my symptoms were very similar to the corpse control technique."

Gu Chuqing frowned and pointed out the key point: "Ancestor suspects that one of the other Zhuyou families is targeting our Gu family?"

Mu Tongguang said "hmm": "That's why I asked you to take over Hei Wuchang's mission. The two things may be related."

Gu Chuqing lowered her head, her dark eyes darkened, and she fell into deep thought.

Mu Tongguang saw this and did not disturb her.

After a while, Gu Chuqing frowned and said, "I won't be able to figure this out for a while. Let's go back first, my eldest brother is still waiting over there."

These things are too complicated and full of mysteries. We can only find out the truth after we have more clues.

Mu Tongguang nodded, turned around, and walked to the top of the mountain with Gu Chuqing.

——

The night wind is cold.

The mountain wind brought a chill, waking up all the plants on the mountain. The mountain, which was previously as calm as a dead thing, returned to normal after the Yin Yan Stone broke through the ground.

The top of the mountain was in a mess, and several large trees had fallen to the ground in the previous battle.

After all the evil spirits were eliminated, Gu Yao stepped out of the protective formation and surveyed the surroundings at close range to see if there were any clues.

After the previous incident, Gu Yao was keenly aware that things were not simple.

Xintian District is a prosperous area of ​​Qi City. Even if the Inner Ring Expressway is relatively remote and evil spirits gather, it is impossible to make any noise.

Although accidents have indeed occurred frequently in the Xintian inner ring recently, he didn't notice anything until Gu Chuqing told him that there was something strange here.

Everything here seems to be blocked by something.

It doesn't take much thinking to figure out that this must be man-made.

The things that just broke out of the ground are only things that affect the changes of those evil ghosts, but they are not the key to isolating the atmosphere here.

Therefore, there must be something else around here that they haven't discovered yet.

Gu Yao frowned and carefully searched around.

"Brother, what are you looking for?"

Gu Chuqing and Mu Tongguang returned to the top of the mountain.

"I want to see if there is a formation that shields this mountain." Gu Yao turned his head and replied, and then said: "You and I are not the only ones in Kaoshi who can walk the yin and yang. The two Yanshi I met that night also have great eyesight.

Not weak, but such a big thing happened here, but they, like me, didn't notice anything, so..."

Mu Tongguang: "I have been in the market for many days. I passed by this area during the day and found nothing unusual."

If he hadn't been close here tonight, he wouldn't have noticed anything different here.

"Let me take a look." Gu Chuqing frowned, her starry eyes flashing with sharp light.

Gu Chuqing's eyes are a sharp weapon for walking between yin and yang.

She can accurately judge the trends in the aura of the Yin and Yang realms without the help of any external objects.

Although the practitioners' methods are unpredictable, no matter whether they are formations or runes, as long as they are performed, there will be traces left behind. And these traces can very likely disrupt a place's aura.

As long as Gu Chuqing follows the trend of the aura, he can usually find the cause.

As expected, Gu Chuqing stood at a high place and looked down at the mountain. Without much effort, she found something that made Gu Yao suspicious.

"There is something strange on the mountainside."

After saying that, without waiting for Gu Yao to reply, he put his feet on the ground to gain strength, raised his energy and flew towards the mountainside.

When Mu Tongguang saw this, his five fingers formed into claws, and he sucked the toolbox that Gu Chuqing left on the ground into his hand. He stretched out his long arm, picked up Gu Yao, and chased after Gu Chuqing.

——

On the mountainside, a strong wind passed by.

Gu Chuqing stood in the dark night, like a swallow flying at night. In a few jumps, he pulled out seven iron nails from seven mulberry trees on the left side of the mountainside.

Gu Chuqing looked at a few iron nails with a dark light in her hand, and her forehead instantly frowned.

With a slight tremor in her heart, she threw away the seven iron nails, then quickly bit her middle finger and typed an order on the nails.

As soon as the order was issued, the seven iron nails instantly turned into a pool of molten iron.

Gu Yao, who was chasing after him, asked anxiously: "What's going on?"

Gu Chuqing looked solemn: "Cassia nails."

Gu Yao was shocked: "Are you okay?"

The Cassia Nail is the most sinister thing in Taoism.
