Chu Xian knew what the other party was thinking, so he nodded and said, "I wonder what the Black Dragon Priest thinks, will the Thirteen Witch Ancestors die under the scorpion tail thorn of the Four Witch Ancestors?"

The Black Dragon Priest's expression changed, and he even got up and walked back and forth in the hall.

Then, the Black Dragon Priest looked at Chu Xian and said in a very certain tone: "If it is the scorpion tail thorn of the Four Witch Ancestors, then the Thirteen Witch Ancestors are indeed unable to resist, but the Four Witch Ancestors have fallen thousands of years ago, and they have not been born for thousands of years, how can it be ......?"

Chu Xian already knew what he wanted to know, and it can be said that the clue he got now is very important.

At the beginning, everyone was trapped and stumped by the cause of death of the Thirteen Witch Ancestors, and it was because they couldn't figure out how the Thirteen Witch Ancestors died, so the whole case could not proceed.

Because, in everyone's consciousness, there is nothing in this world that can quietly kill the Thirteen Witch Ancestors.

This is the biggest difficulty, but again, everything has two sides, and this biggest difficulty, sometimes, will become the easiest point to break through.

Because, there is no other way to kill the Thirteen Witch Ancestors in this way, as soon as the scorpion tail thorn of the Four Witch Ancestors is thrown, it can be determined almost immediately that the Thirteen Witch Ancestors died under the scorpion tail thorn of the Four Witch Ancestors.

Although there are still too many doubts about this speculation, there is no doubt that it is a great development.

And Chu Xian already had a follow-up in his heart.

"Black Dragon Priest, please gather the noble and strong people, keep an eye on this place, and no suspicious people can enter or leave. Chu Xian admonished at this time.

The black dragon priest didn't know why, and wanted to ask again, but Chu Xian had already turned around and went out immediately.

According to historical records, the Four Witch Ancestors fought with the Holy Ancestor of Taizong 5,000 years ago, and were cut off by the Holy Ancestor of Taizong with a sword.

This matter is not recorded on the Wu Clan's side, after all, it is a shameful thing, so it is normal that it has not been recorded, but on the side of the Holy Dynasty, there must be a record.

Chu Xian went directly to Xiao Yu's Zhongshu and talked about it, because he wanted to check such a thing as a scorpion tail thorn, Xiao Yu's energy was obviously more than his own.

When Xiao Yu heard this, he also attached great importance to it, and immediately went to check it in person.

Soon, Xiao Yu found out.

"Chu Xian, the scorpion tail thorn of the four witch ancestors of the Wu clan was indeed cut down by the Holy Ancestor of Taizong, and the Holy Dynasty did take it back and stored it in the Holy Ancestor Immortal Palace, but it was just ......" Xiao Yu said here, pausing with bitterness on his face.

Chu Xian was very anxious, so he asked what it was.

Xiao Yu sighed and said, "Do you remember the previous Asgard unsolved case?"

Chu Xian was stunned: "Of course I remember, this case has been solved, and the lost Heavenly Demon Bone Bead has been recovered, but the Tianhua monk has not yet been brought to justice." ”

Xiao Yu shook his head at this time: "What I am telling you now is a secret of the Holy Dynasty, you listen to it, and you must not spread it." ”

Chu Xian's heart jumped, and he was already guessing, and at this time, Xiao Yu continued: "The case of the theft of the Immortal Palace back then was not as simple as recorded in the file, after all, this was a matter that damaged the face of the Holy Dynasty, so it was just a record of the not very important Heavenly Demon Bone Bead, but in fact, the treasure lost in the case of the theft of the Immortal Palace back then was not just a Heavenly Demon Bone Bead?"

Chu Xian's eyelids jumped wildly at this time: "Mo Fei, the scorpion tail thorn was also ...... at that time"

Xiao Yu nodded: "Yes, the scorpion tail thorn of the Four Witch Ancestors was also stolen at that time, this thing is too important, but it has not been recovered, so it has not been written into the file, these years, even in the Shoufu Pavilion, only a few immortal officials know, but this matter, the Holy Dynasty has also been tracking, but there is no result, and, in addition to the scorpion tail thorn, a few things were lost back then." ”

When Chu Xian heard this, the expression on his face could be described as quite exciting.

He originally thought that the case of the theft of the Immortal Palace had already been revealed, and only one Tianhua monk was not caught, but now it seems that he is just the tip of the iceberg of this big case.

And what is extremely scary is that if the scorpion tail thorn was stolen ten years ago, then today, the thirteen witch ancestors were assassinated by the scorpion tail thorn, doesn't it mean that the murderer behind it has been planning for ten years?

No, it's not.

Chu Xian immediately denied his speculation, even if he was a powerful person, it was impossible to predict the prophet, and it was impossible to know that ten years later, the Thirteen Witch Ancestors would come to visit the Holy Dynasty.

But it is certain that the real culprit of the assassination of the Thirteen Witch Ancestors must have something to do with that Tianhua monk, and it should have been when it was rumored that the Thirteen Witch Ancestors were going to visit the Holy Dynasty that the other party began to plan.

So think about it carefully, when was it first rumored that the Thirteen Witch Ancestors were going to visit the Holy Dynasty?

It was three months ago, when Yank came back.

Chu Xian had already demarcated a time frame at this time, three months, which was the earliest time that the other party might know that the Thirteen Witch Ancestors were going to visit the Holy Dynasty, that is, from that time on, the other party began to plan to assassinate the Thirteen Witch Ancestors.

Over there, Xiao Yu said: " Unexpectedly, the murder weapon that is most likely to assassinate the Thirteen Witch Ancestors is actually the scorpion tail thorn stolen ten years ago, that is, we didn't associate these two things together, and even ignored this thing, now think about it, there are indeed only scorpion tail thorns in this world, it is possible to kill a master of the level of the Thirteen Witch Ancestors at once, not to mention the Thirteen Witch Ancestors, even if someone sneaks up on me with the scorpion tail thorn, I can't resist it, but, even if I can't resist it, the Thirteen Witch Ancestors can't be unaware, a master like him, if someone wants to be unfavorable to him, he will definitely be alert in advance, how can there be no signs？”

Chu Xian nodded, this was also what he couldn't figure out.

Because, even if the real murderer assassinated the Thirteen Witch Ancestors with a scorpion tail stab, it was impossible to succeed in the assassination without alarming others, even if the Thirteen Witch Ancestors were hit, they could warn others, but in fact, the Thirteen Witch Ancestors did not make any warnings at all, or even did not resist.

Is it that the real murderer's cultivation is too high and his actions are too fast? So that even Wu Zu can't be on guard?

According to Xiao Yu, unless it was Taishi Lu Yan who made a move, he might be able to catch the Thirteen Witch Ancestors off guard, but obviously Taishi Lu Yan could not be the murderer.

Or is it that the real murderer's ability is close to Master Lu Yan?

If so, it would be terrible.

Xiao Yu also thought of this, his brows were furrowed, and his expression was solemn.

"Chu Xian, I will order all states and localities to make every effort to track down the whereabouts of Monk Tianhua, this case, even if it is not done by him, will inevitably have nothing to do with him. Xiao Yu said at this moment.

Chu Xian nodded: "What Lord Zhongshu said is right, as long as you catch the Tianhua monk, you will definitely be able to open a breakthrough." ”

Obviously, it was originally a clueless case, but at this moment, with Chu Xian's efforts, a hole was finally opened, although this clue is not easy to check, but at least there is a direction, not like before, as if a headless fly is rambling around.

For Chu Xian, Xiao Yu was obviously very satisfied: "Chu Xian, no matter what, you have found the clues that are most likely to be the murder weapon, it is considered a breakthrough, there are still a few days left, if you can find more clues, even if the case cannot be solved, I will also think of helping you keep your official position." ”

Chu Xian was overjoyed, and naturally thanked Xiao Yu.

After going out, Chu Xian was still thinking, thinking about how the real murderer did it. At this time, Chu Xian continued to substitute himself into the role of the real murderer.

In other words, after having something like a scorpion tail thorn in your hand, how to do it in order to successfully assassinate the Thirteen Witch Ancestors. Chu Xian found that even if he had a scorpion tail thorn in his hand, it was impossible to assassinate the Thirteen Witch Ancestors, after all, the Thirteen Witch Ancestors were very strong, almost equivalent to Xiao Yu's Zhongshu.

Such an immortal-level master, unless the real murderer is also a Dao immortal, it is impossible to succeed.

Of course, if you have to say yes, unless the Thirteen Witch Ancestors didn't move at that time, they didn't resist, and sat down to let the real murderer do it.

Chu Xian was originally just thinking nonsense, but at this moment, he was suddenly stunned.

His idea just now, at first glance, is indeed a fantasy and a cranky idea, but if you think about it carefully, it becomes the only possibility.

All along, he thought that the fierce beast that assassinated the Thirteen Witch Ancestors was a master, and it was also a Dao Immortal-level existence, but what if it wasn't.

If the Thirteen Witch Ancestors did not resist, then even if it was an ordinary martial artist or a cultivator, with the scorpion tail thorn of the Four Witch Ancestors, he could kill the Thirteen Witch Ancestors.

Chu Xian just has such tenacity, if he can't figure out a question, he will keep thinking about it, and in the end, Chu Xian even began to assume that it was the Thirteen Witch Ancestors who deliberately did not move and let the murderer kill him.

Before you know it, it's getting dark.

In the past few days, Chu Xian's investigation of the case can be said to have reached the point of forgetting to sleep and eat, and the people in the family are also trying not to disturb Chu Xian and not interfere with his investigation.

Although Li Ziyun came every day, she only helped take care of the affairs of the family, as for Wang Yanchan, she hadn't seen her for several days, Chu Xian estimated that it was Wang Shenling who grounded her.

Obviously, with the passage of time, if he can't find out the truth, then his career will be ruined, and Wang Shenling will definitely not let Wang Yancian come back to have any entanglement with him.

This is not to blame Wang Shenling for being snobbish, if it were someone else, he would do the same.

However, for Chu Xian, this made him breathe a sigh of relief, if Wang Yancian kept coming like this, he really didn't know how to treat her.

It's not that he treats her, but that Li Ziyun will help him find ways to get along with her, and now in this situation, Chu Xian can't ask for it.

As soon as I thought of Li Ziyun, I saw her walking in with a bowl of porridge.

The porridge is very fragrant, even if it is far away, you can smell it, obviously Li Ziyun took a lot of thought to boil it, seeing Chu Xian, a trace of distress flashed in Li Ziyun's eyes, so he stepped forward and said: "Rest, I will help my aunt boil it, you drink it while it is hot." ”

Chu Xian felt a trace of guilt in his heart at this time.

During this time, although no one at home said anything, they were sure that whether it was their mother, Li Ziyun or Concubine Luo, they must be worried about themselves.
