Even if there doesn't seem to be anyone else around, it's better to be cautious. He had already discovered Bai Ziqi's concern for him, although the reason was not clear.

「！！ How can you be sure......." Mirror Daqi took a few breaths before reacting, "Oh, when did you do it to him?" It has been staying on He Lingchuan, why didn't he even find it?

This master, it is getting more and more unable to keep up. "Last night."

He Lingchuan gave this little hint and did not expand it again.

He arrested the fugitive with Bai Ziqi last night, and Cheng Yu was captured by him himself.

At that time, Cheng Yu was injured by the lamp spirit and fell into a coma, and He Lingchuan held him in his hand, but he was actually faced with two choices:

Suck his soul out with a mirror, or use a nightmare.

It is the easiest to use the soul mirror, but it is easy to be suspected by Bai Ziqi afterwards, after all, the last person to contact Cheng Yu was He Lingchuan.

Sending out Nightmare is a long night, after all, Nightmare still has to sneak into Cheng Yu's dream realm and design a trap to kill him. However, the advantage is that Cheng Yu can still wake up after being brought back to Baishaqi and say two words-

Yes, this is He Lingchuan's request for Nightmare.

The nightmare was only started after Cheng Yu fell into a coma for the second time, so Bai Ziqi would naturally recalculate the time when he was attacked, and He Lingchuan would be able to clear his suspicion.

So he decided on the latter plan almost in the blink of an eye, and then wiped the Gu Luo branch loaded with nightmares to Cheng Yu's nose.

At that time, Cheng Yu was already in a coma, and it was very convenient for the nightmare to fall asleep. Now it seems that this risky move has been played again.

After Bai Ziqi captured Cheng Yu, he set up ever-bright lights around him, and any yin approaching would trigger an alarm.

But the nightmare lurked in Cheng Yu's dream one step earlier, how could it touch the police? Bai Ziqi only arrived in Baisha yesterday, and gave He Lingchuan a dismount. But he didn't know that he was also calculated by He Lingchuan.

After He Lingchuan finished the song, the fierce tiger Jiao Yu ran over, holding a cloth bag in his mouth, and looked up at him and said, "The prince has something to give."

He Lingchuan perked up and jumped off the ground to take the cloth bag: "Thank you." Jiao Yu said, "The prince said that this is a secret. I'll step back first." He didn't dare to look at it.

He Lingchuan patted the tiger's head, turned around and went back to the house, closed the door, and put an enchantment again, and then opened the cloth bag.

"Oh, I've finally got it!" The mirror whistled. He Lingchuan didn't know how it came out.

Inside the cloth bag was a box and when I opened it, there was a stack of letters. This is the last thing Fushiyama sent as promised:

An epistle with a black motif on the motif of the black dragon.

He Lingchuan helped him catch Cen Boqing, and also gave Zhong Sun Mou's death, which can be regarded as overfulfilling the task entrusted by Fushan Yue, and he should get all the rewards.

These books are all in the imperial study of the king of Chiyan, and everyone who wants to enter it is a life and a death, let alone slowly collect related objects. After Fuyama was promoted to the crown prince, he had just obtained the right to enter and leave the imperial study.

He Lingchuan looked at the things in hand and smiled bitterly: "Stingy, don't let me take advantage of the slightest advantage."

There are more than a dozen pieces of paper, all with different background colors, except for a few pieces of letterhead, some of which are even torn from different books. Of course, He Lingchuan wanted to read the whole book, but Fu Shanyue only tore off the part of the record with the black Jiao pattern, which should be for the sake of secrecy.

After all, these are all things taken out of the imperial study of the Red Yan Kingdom, and they have their secrets.

At the top is a silk book, which opens like a scroll, long one. Because of the special refining, the silk surface is slightly old, and there is no moth or powder.

It was the first time He Lingchuan had seen so many black Jiao patterns gathered. He counted them at random, and there were eighteen of them.

Each pattern is hand-painted, the painter is skillful, every stroke has charm, and even the eyes of the black Jiao are painted vividly.

On the edge of each black Jiao pattern, the address and period of the painting are attached.

The earliest can be traced back to 2,100 years ago, the Yangxing tribe in the Shahe River Valley.

Where is the Sand River Basin? He Lingchuan thought for a long time and gave up. Make a note of the place name and look it up later.

He also has no impression of the last few addresses, and the period is relatively old. Then, he saw the black Jiao pattern of the Yuan Kingdom, a total of two.

Later, He Lingchuan was taken aback again, because the three words "Panlong City" came into view!

The last five motifs on this silk are all from Panlong City.

What's more, the painter also specially marked that these five patterns are all drawn from the same black Jiao emblem in Panlong City, but the period is different.

He Lingchuan quickly converted, these five patterns were painted in the third year, eleventh year, seventeenth year, twenty-fourth year of the Panlong calendar, and ...... Thirty-one years!

Panlong City has existed for 32 years, so the fragments selected by the painter almost run through the Panlong era. It's like a microcosm of an era.

Why did he do it?

He Lingchuan directly pulled the silk book to the end to see the payment. The painter's name is Song Wei, and he calls himself Weishan Zhenren.

The first ten patterns of this person said to be on silk were obtained from ancient books or collected from ruins, only the black Jiao patterns of Yuanguo and Panlong City were surveyed and mapped on the spot when the city was still there and the people lived in peace, and there was almost no error.

In other words, he himself went to Yuanguo and Panlong City successively, and later gathered the patterns at hand to make this silk book.

In addition to the black Jiao statue on the south gate of Panlong City, He Lingchuan did also see the black Jiao pattern in the streets and alleys. The neighbor's child is chubby, and the content of the graffiti on the wall is black Jiao a few times, but the painting is not good, and the Jiao head is painted as a dog's head.

He Lingchuan carefully observed the five patterns of Panlong City, and at first glance they all looked the same nonsense, drawing the same emblem.

However, Song Wei is not so boring, and has painted five identical patterns for more than 30 years.

He Lingchuan looked down, and there were still subtle differences between these five Jiao heads.

The eleventh year of the Panlong calendar is a little longer than the three years of the Panlong calendar, with a little longer sharp horns and two more beards.

It's just such a slight change, or He Lingchuan almost used a magnifying glass to find it.

The pattern changes in the twenty-four years of the Panlong calendar are obvious, the Jiaoshou looks one size larger than the previous ones, the face is longer, the beard is more powerful, and the eyebrow protrusion is more obvious.

The most important thing is that the sharp horns on its head have actually begun to decentralize!

All the black Jiao patterns that He Lingchuan had seen before, including those on this silk book, including those he had seen with his own eyes in Panlong City and Yuanguo, had two bare sharp horns on his head!

The branches are like the antlers of a deer. Or rather, like a dragon.

He Lingchuan took a light breath and went to look at the last pattern.

But to his disappointment, the head did not evolve further, but fell back to the sharp horns, and the beard was missing a few locks.

It's probably about the same as the pattern of the eleventh year of the Panlong calendar.

In the past 20 years, I have evolved into a loneliness, and at the end of the day, I have changed back.

He Lingchuan went to look at the two black Jiao patterns in Yuanguo.

The interval between these two patterns is not long, that is, half a year, two years.

After King Yuan took over the throne from the previous demon king, the Yuan Kingdom only existed for four years, of which three years were occupied by war. During the war, the border management was very strict, and it was not easy for Song Wei to squeeze into the Yuan Kingdom, and the Yuan Kingdom was probably not as friendly to outsiders as Panlong City, so he only painted two paintings.

The two patterns are also slightly different, and the head of the second one has grown compared to the first.

This is very interesting, especially the five patterns of Panlong City, like time-lapse photography, listing the changes of the same Jiaoshou imprint in different periods.

What is the use of the black Jiao pattern and why does it change?

He Lingchuan, like Song Wei, does not believe that this change is artificial, but rather a change in the pattern itself.

In the Yuan Kingdom, in Panlong City, and even earlier monuments, what contributed to the "growth" of Jiaoshou?

Song Wei gave his own speculation.

This sigil may have been a totem, used to rally the faith of the city's citizens, like the ubiquitous temples of Bega.

The growth of the head of the Jiao reflects whether people are religious to it.

Or perhaps, this Jiaoshou is the mark of some hidden immortal organization. With it, the city can get a steady stream of support from the immortals. Because, these places where the Jiaoshou mark existed were relatively rich, as if they had been blessed in the dark.

Blessing? He Lingchuan thought for a moment.

He didn't know the situation in Yuanguo back then, but the Chipa Plateau backed by Panlong City was indeed very rich, and he had everything he wanted, from grain, minerals, wood to medicine, furs, and fishing goods, otherwise he would not be able to support the Panlong army and civilians for so many years.

Bega has repeatedly and secretly made it bad, but to no avail.

Is this the Jiaoshou mark only appearing in the land of abundance, or is it rich locally because of the Jiaoshou mark?

Which is the cause and which is the effect? It's hard to say.

Seeing that Song Wei was inconclusive, he was a little disappointed, and then looked through other information.

There are all kinds of letters, pages, and codex, usually the pages are yellowed and brittle, and they will lose powder, so you have to be very careful when flipping through them.

It's all old pieces that are old.

He Lingchuan frowned. Fu Shanyue can only find these old objects, which shows that there is no new progress in the research of black Jiao.

There is even a saying that Jiaoshou may have been left by the Immortal Sect along the way, used as a channel for communication between immortals and mortals, and commanded them to seek to seize the world.

He Lingchuan also turned to a battle report sent back by the female cadre from within the Yuan Kingdom, which provided a lot of information about the Thousand Star City of the Yuan Kingdom, including what had happened in the city recently, what orders the royal court had issued, the salaries and prices in the city, and so on, all of which were summarized in one or two sentences and were very concise.

Among them, the black Jiao pattern was also mentioned, saying that there was a black Jiao pattern opposite the spout's residence, and he himself observed it all day long, but he never saw this mark glow and produce any power.

But just once, the horses pulling goods on the street lost control and crashed into the wall with the cart. The wall wasn't thick, and it was supposed to be a bump. However, the horse hit the mark of the black Jiao, its own tendons and bones were broken, and the cart also fell apart, but the black Jiao pattern was still intact.

It was then that the spies realized that there was a very secret barrier outside this mark.
