Starting with a useless yellow dog, he swept through the immortal realm.

They certainly know how to pick their time. It's already nighttime at Hai Shi (9-11 PM), and according to people's daily routines, they'd probably be fast asleep by now.

Moreover, the time of Hai (9-11 PM) is generally when the city's defenses are most lax.

The missing children follow a very regular pattern: they are all missing in alternations, one boy and one girl.

So it must be a boy today, and of course, it wasn't just Song Xun who noticed this.

Tang He has already marked all the families in the city with children under the age of five, totaling fifty-nine families, including thirty-nine families with boys and twenty-eight families with girls, including eight families with both boys and girls.

"There are 39 in total, which covers a fairly wide range."

"Yes, I have already deployed soldiers to secretly observe the vicinity of these thirty-nine households."

Tang He sighed slightly at this moment, but unfortunately he was just an ordinary person and could hardly understand the other party's reasons for doing so.

"Uncle Tang, don't rush, let me think about it."

Song Xun sat with Jiang Wanfeng, looking at the records of the missing children, trying hard to think of the connections between them.

Song Xun and Jiang Wanfeng were not professional investigators, so at this moment they could only keep thinking about the connection.

Song Xun was somewhat better off, having watched many crime dramas in his previous life, but Jiang Wanfeng was in a real bind.

Ask her to take up a sword and kill the enemy, she would agree without hesitation, but asking her to investigate and solve cases would be the death of her. However, Jiang Wanfeng felt extremely anxious when she thought of the missing children.

At this moment, Song Xun was already deep in thought.

Now that it has been determined that it was the work of demons, can we try to find the reason in their motives?

Demons would never kidnap children for no reason. Song Xun had read so many fantasy novels, and there were naturally many such plots in them, all for the sake of their own cultivation or some other special needs.

If it's not for some kind of ritual, why would they need to catch one boy and one girl? And as of today, there are exactly four girls and three boys.

In other words, the earlier decision to start with the boy tonight was probably correct.

So are there any other connections? If it's just a requirement of four boys and four girls, then there's no need to catch one every day.

Why not just catch them all in one day? Why change the gender every day?

Moreover, they only arrest one child per day.

Song Xun then looked at the month of the missing child.

In order, they are October, January, February, April, May, July, and August.

There's no connection between them.

Having thought this through, Song Xun found himself in a mental stalemate.

"Song Xun, did you figure it out?"

Not yet.

Jiang Wanfeng had already given up, since she was really not good at this. Song Xun naturally wouldn't make things difficult for Jiang Wanfeng, since Jiang Wanfeng's desire to kill the person who kidnapped the child was no less than Song Xun's.

"If only it were as easy as practicing swordsmanship, I'd love to chop that bastard down with one sword."

When Jiang Wanfeng mentioned sword practice, Song Xun remembered that his "Beast Dao Immortal Record" was currently having a phantom character practice the "Eight Trigrams Sword" skill.

This "Eight Trigrams Sword" was a sword technique that Jiang Wanfeng chose for Song Xun when the two left the Ten Thousand Swords Sect. Once mastered, the sword technique could be unpredictable and varied within the Eight Trigrams, making it very practical in combat.

However, after leaving the Ten Thousand Swords Sect, the two were on a long journey, and Song Xun was unable to find time to cultivate himself. Therefore, he left the Eight Trigrams Sword to the phantom to cultivate on his own.

At this point, they had all reached the entry-level stage of cultivation.

Song Xun immersed his consciousness into the "Beast Path Immortal Record," attempting to find helpful information, but unfortunately, it was of no use.

Song Xun had already gone to the homes of the seven families where the children had gone missing, but unfortunately the Demon-Searching Talisman had no effect.

It seems the other party is also at the Nascent Soul stage, or has other means of concealment.

After all, the Demon-Searching Talisman is quite effective, but firstly, the demon being searched for must be of a lower cultivation level than the searcher, otherwise it will be useless.

Of course, Song Xun was not worried that the other party's cultivation level was too high, after all, Zuoping County was not far from Yanbei City.

Previously, because of the Tiger Hall incident, the Beast Taming Sect specially placed a sensing beast in Yanbei City. As long as any demon or monster above the Refinement Void Realm is within a certain distance of Yanbei City, the Beast Taming Sect will be able to sense it.

Unless the other party knows in advance and uses a very strong concealment technique, it will be detected.

Since the Beast Taming Sect was only recently established with great effort, the outside world is likely unaware of it yet, so the information from this sensing beast is quite accurate.

The range that the sensing beast can perceive happens to cover Zuoping County.

Therefore, Song Xun was 80% certain that he could handle the opponent who was below the Refinement of Void Realm.

Unfortunately, Song Xun couldn't find a way to help with the search in "The Immortal Record of the Beast Path".

After casually glancing at the Bagua Sword, Song Xun suddenly noticed the eight trigrams on it: Kun, Zhen, Li, Dui, Qian, Xun, Kan, and Gen.

Then Song Xun suddenly realized that the birth months of the previous seven children corresponded exactly to the first seven trigram positions.

This major discovery instantly excited Song Xun, who quickly went to find the remaining thirty-nine families with boys in the city one by one.

Seeing Song Xun's expression, Jiang Wanfeng and Tang He naturally understood that Song Xun had made a discovery, and immediately waited quietly for Song Xun to finish reading the children's information.

Soon, Song Xun found three children born in November among the thirty-nine boys.

According to the correspondence of the Eight Trigrams, the last remaining trigram, Gen, corresponds to the winter solstice in the month of Zi, which is November.

"Xiao Song, have you discovered anything?"

"Uncle Tang, I've made a discovery. My initial estimate is that this demon will target one of these three children tonight."

Tang He took the three children from Song Xun's hands, and was also very puzzled, wondering how Song Xun had made that determination.

After Song Xun explained it to Tang He and Jiang Wanfeng, Tang He suddenly understood.

Indeed, the actions of demons cannot be deduced using human reasoning; no wonder he couldn't find any connection between them before.

Jiang Wanfeng, at this moment, also seemed to understand but didn't quite, and echoed along.

"Song Xun, I think you're right, that's what I think too."

Song Xun looked at the dazed, big-eyed, adorable swordsman in front of him, nodded as if he understood perfectly, and gently rubbed his head.

"I'll send men down right now to defend it heavily. I refuse to believe it can escape this time."

"No, Uncle Tang, we'll alert them. Too many people might backfire."

"That's true, that's true."

Tang He wasn't stupid; it's just that the recent pressure had caused him to make some mistakes in his decisions.

"Tonight, Jiang Wanfeng, Huang Bulang, and I will each be responsible for one of the houses."

"Like catching a turtle in a jar!"
