This is it.

Mu Jianyun stood in front of the phantom of the small bronze door, took a deep breath, gathered the mana in his body in his hand, and then knocked lightly on the door of the phantom.

"Knock Knock ......"

A low knock on the door echoed in the silent mountain forest, and the small bronze door, which obviously looked like a phantom, reverberated like a physical entity under Mu Jianyun's soft knock. After three knocks, Mu Jianyun withdrew his hand and saluted respectfully.

"Mu Jianyun, the messenger of the lower 'Spirit Imperial Platform', has something important to come to meet the Qilian Mountain God, and I hope that the Mountain God can give him a meeting. ”

Compared with ordinary police officers, the "witnesses" that Mu Jianyun can find as a "spirit envoy" are not limited to "humans", and they are more reliable, but only if ...... "witnesses" are willing to see him.

Mu Jianyun stood in front of the small bronze door, waiting for a long time but still not getting any answer, and the small bronze door showed no sign of opening.

Really...... Still not there?

Mu Jianyun sighed softly, the tempers of the mountain gods in various places are different, and their whereabouts are also erratic, whether they can be found depends on luck, but the luck of the past few days does not seem to be on Mu Jianyun's side.

Mu Jianyun stood in front of the door for a while, and finally had no choice but to plan to go home. But just as he was about to leave, he heard the bronze door behind him suddenly "creak" open the crack.

“…… Knock every day, bothered...... Disturbing dreams!"

Impatient complaints accompanied by a sleepy-eyed face appeared behind the door, only to see a childish young man in a white robe glaring at Mu Jianyun angrily, his clear blue eyes revealing dissatisfaction.

"You, you are ......?" Mu Jianyun looked back at the young man behind the door, his face a little surprised.

"Why, since you're looking for me, you don't even know what I look like?" The young man in white frowned, the cinnabar between his eyebrows reflected the snow-white skin, and the young man's face became more transparent and beautiful, but such a beautiful face was full of "disgust" at this time.

"I'm the guardian mountain god of Qilian Mountain, and my good retreat has been interrupted by you, it's really ......"

“…… Hug, I'm sorry, I don't mean to offend, and I hope that Lord Mountain God will forgive me. Mu Jianyun came back from his surprise, and immediately bowed his hand again and apologized respectfully.

"Come on, if there's something to say, I'm busy. The young man in white yawned and didn't open the door completely, it seemed that he had no intention of inviting Mu Jianyun in, and Mu Jianyun certainly understood the other party's attitude when he saw this, so he just stood in the rain and explained the purpose of coming here as briefly as possible.

"I'm here to investigate a bloody case that happened here 10 years ago. Mu Jianyun said. "Ten years ago, there was a shooting in the Qilian Shanwei area, and a teenager who was only 13 years old at the time was accused of shooting his stepfather with a shotgun, do you know anything about the case?"

"I don't know. The young man in white replied succinctly and crisply. "Do you know how big the entire Qilian Mountain Range is? I am a mountain god, and I want to be in charge of the terroir and mountains of such a large area, how can I bother to take care of the trivial matters of you human beings, and it was ten years ago. ”

"This ......" Mu Jianyun was stunned, and he was so stunned that he didn't know how to answer. "You really ...... Isn't it impressive?"

"If you don't remember, you don't remember, I don't care about what you Lingyutai want to investigate, but I have no obligation to cooperate with you. The young man in white said, turned sideways slightly, and reached out to the door. "Also, the rainy season is basically my retreat period, so if there is nothing else, don't bother me. ”

After speaking, the young man in white turned around and walked into the door, it seemed that the door was about to close, Mu Jianyun was in a hurry, and he didn't even care about any etiquette, so he hurriedly stepped forward and grabbed the edge of the door, and blurted out the eager words:

"Wait a minute! I just want to ask...... In this Qilian Mountain, is there a thousand-year-old plane tree?"

“…… Millennial Sycamore?"

The figure of the young man in white seemed to pause, he turned around, his blue eyes stared at Mu Jianyun's face, and opened his mouth coldly:

"You...... Why do you want to know this?"

According to the account of the young man named Jiang Yao, who committed the crime that year, he had recounted that he had taken refuge from the rain under the thousand-year-old plane tree the night before the accident. Seeing that the reaction of the young man in white seemed to be playful, Mu Jianyun suddenly ignited hope and hurriedly recounted.

"If you can really find this tree, maybe you can solve some of the truth about the incident back then, but later the police couldn't find the tree, and even the locals said that there was no such plane tree......"

"Hmph, of course they can't see that tree, because that tree is indeed not in Qilian Mountain, or should it be said...... Except for "a special moment", it has never appeared in Qilian Mountain. The young man in white said calmly.

"...... this, I don't understand......" Mu Jianyun was a little dazed. "This 'thousand-year-old plane tree'...... Does it really exist?"

"......" The young man in white glanced at Mu Jianyun, ignoring his doubts, but suddenly threw out a question: "The child who committed the crime back then came here ten years ago?"

"Yes...... It was about the same time as it is now. ”

"Was it the rainy season ten years ago...... "The young man in white muttered, as if thinking about something.

"Do you have anything in mind about that case?" Mu Jianyun asked anxiously.

"As I said earlier, the rainy season is my retreat period, and I don't know what you said. The young man in white raised his eyes, his attitude still indifferent. "But when it comes to the rainy season ten years ago, something unusual happened near the Qilian Mountains. ”

"Something unusual?"

"Do you know that Zhou Shan is not going to do it?" said the young man in white suddenly.

"Buzhou Mountain...... Is it the sacred mountain that suppressed Chi You's head in ancient times?" Mu Jianyun was a little surprised, I don't know why the mountain god in front of him suddenly mentioned this. "I remember that the location of that mountain has long been unknown for historical reasons, and no one knows where it is......"

"That's right, because the location of Buzhou Mountain has always been 'not fixed'. The young man in white leaned against the door and spoke. "There is a naturally formed barrier around Buzhou Mountain, which makes it form an independent space-time space, floating around like a ghost, and there is no fixed law at all when it will appear in the earth boundary. But the most recent one it appeared was during the rainy season ten years ago, and it happened to be connected to the end of the Qilian Mountain. ”

"Qilian Shanwei?" Mu Jianyun's expression froze, and something immediately came to mind in his mind. "Is it possible...... That thousand-year-old sycamore tree is ......"

"Yes, that tree should be the 'Sycamore Tree' on Buzhou Mountain. The young man in white glanced at Mu Jianyun meaningfully and said. That is, the thousand-year-old tree that was transformed into a thousand-year-old tree by the severed head of Chiyou back then. ”

"What!?" Mu Jianyun's face changed drastically. "Could it be that Jiang Yao and they stumbled into Buzhou Mountain by mistake back then?"

"Maybe, who knows. The young man in white shrugged his shoulders and said. "Okay, I've already told you everything I need to say, if there's nothing else to do, you can go. ”

"Wait, wait...... I have one last question. Seeing that the young man in white was about to give an eviction order again, Mu Jianyun hurriedly spoke again.

"What's the matter, if you have something to say, say it quickly!" the young man in white frowned, and his patience seemed to have run out.

"I want to know...... The enchantment around Zhou Mountain should not be traversed by ordinary people, right? But Jiang Yao and the others went in back then...... Under what circumstances would they, as ordinary people, be able to pass through the barrier of Buzhou Mountain and go under the thousand-year-old plane tree?" Mu Jianyun asked in one breath.

"There is only one reason why ordinary people can cross the barrier, and that is that the barrier was temporarily opened at that time. The young man in white shook his head, as if he had heard a meaningless question. "I know you still want to ask, 'Who opened the barrier?' How do I know, if it wasn't for the kid named Jiang Yao and his stepfather who was killed later, it was a 'third person' who opened the barrier. ”

"...... 'third person'?" Mu Jianyun suddenly "chuckled" in his heart.

"I know so much, and I can't help the rest, so you can check it yourself. After speaking, the young man in white shook his hand, ignored Mu Jianyun behind him, turned around and walked into the bronze door, and closed the door with a "bang".

"Whoa...... Whoa......

The mountain rain was still dripping, but Mu Jianyun's heart at this moment was not as calm as when he came.

Ten years ago, Buzhou Mountain descended here, the thousand-year-old sycamore transformed into the head of Chiyou, and ...... That may be a "third person".

There is really another hidden story behind the current case, and the source is likely to be on Buzhou Mountain, and if there is really a 'third person' who has the ability to open the barrier of Buzhou Mountain, then this person ...... Who is it? Is this person related to the murder 10 years ago?

Mu Jianyun lowered his head and walked in the rain, with a lot of thoughts in his heart.

The information found on this trip was really beyond his expectations, and what was hidden behind this series of new clues may be the truth that Jiang Yao was able to escape from the destiny of "certain death" and was engraved with the "death mark" by the underworld. And now, when Buzhou Mountain has long disappeared, the only remaining clue seems to be this possible 'third person', and this 'third person' also needs to have the power to open the powerful enchantment of Buzhou Mountain......

Speaking of which, the barrier of Buzhou Mountain is very stable, although the gods and demons may be able to cross the barrier on their own, but to break the barrier and let ordinary people enter and exit, it is no less difficult than opening the "space barrier" of the Three Realms, which is basically impossible to do, unless it ......

Mu Jianyun thought about it, and suddenly seemed to think of something, and then took out his mobile phone and sent a message to an internal number in the system, and soon, a copy of the investigation information he needed was sent back to his mobile phone.

"Keel Key...... The Ye family in the south of the city ......" Mu Jianyun looked at the information on his phone, his brows furrowed slightly.

"Is it the Ye family in the south of the city again?I remember that the black sword in the 'Yuanqiu Mountain Incident' is also related to them...... Is this really just a coincidence?"

Mu Jianyun groaned and didn't continue. He put down his phone and looked up at the rain-shrouded sky, a sense of foreboding lingering in his mind.

"It seems...... Gotta go back one more time. ”
