From the moment she sat down, Gu Xuanyan's eyes had been wandering, sometimes to the left, sometimes to the right; even her fingers were having trouble placing their fingers, from not knowing where to put them at the beginning to now groping in her hair.

Before, Zhang San could only judge the other party's condition based on his own experience. However, after acquiring the skill of criminal investigation, everything became clear.

After all, unless they are professionally trained, most people cannot control their micro-expressions. Moreover, in this world, there is not even the concept of micro-expressions, let alone how to control them.

It was obvious that Gu Xuanyan was very nervous at this moment. She looked to the left to think, and to the right to think about how to lie. As the communication became more frequent, these originally subtle micro-expressions could allow Zhang San to easily come up with the answer.

…

"We have arranged for the child named Wang Xiaoming to go down the mountain. Don't worry, he met his family outside the village. If nothing unexpected happens, the child has gone somewhere else now..."

Gu Xuanyan seemed to want to say something, but at this moment Zhang San suddenly interrupted her.

"The trump card you had left should be pretty strong. Now that I think about it, you seemed pretty calm at the time."

Well, the pupils were dilated and the lips were dry, an obvious expression of surprise. However, what Gu Xuanyan didn't know was that if the expression of surprise lasted for more than one second, it would become fake surprise.

"I really can't hide it from you, Third Brother. I do have a trump card in my hand. It was left to me by my father when he died, and its name is - Xing Tian!"

The ancient god of war is worthy of the title of a thousand-year-old family, but is this a deterrent? Or does it have other meanings?

From this point of view, Gu Xuanyan must be quite knowledgeable. With a vague attitude, Zhang San had no interest in what happened next.

But before Zhang San raised his hand to signal the other party to stop, Gu Xuanyan's voice came again. In order to drag Zhang San into the water and tie him to the Gu family's warship, Gu Xuanyan did not hesitate to spend a lot of money! "According to the "Yunji Qiqian·Xuanyuan Benji", "The emperor toured the east to the sea and climbed Mount Huan. He found the Bai Ze divine beast on the seashore. It can speak and understand the feelings of all things. He asked about the ghosts and gods in the world. Since ancient times, there have been 11,520 kinds of spirits and wandering souls. Bai Ze spoke, and the emperor ordered it to be drawn and shown to the world. The emperor then wrote a text to bless evil. "

This is the origin of the national treasure "Bai Ze Jingguai Tu", and also the beginning of the disaster of my secret painting school. "

At this point, even a strong-willed woman like Gu Xuanyan couldn't help but reveal a little sigh. After analyzing her micro-expressions, Zhang San could confirm that her sadness this time was not mixed with any water.

Now that it has started, please don't stop. Zhang San has never had any resistance to such weird things, otherwise he wouldn't have walked for three days to the teahouse to listen to storytelling.

"Back then, the ancestor of the Gu family was an imperial official and had the honor of participating in the compilation of the Bai Ze Jingguai Tu. However, how could a national treasure, especially one that could harm the fortune of the demon race, be easily moved? Even the auspicious beast Bai Ze could not bear the overwhelming karma, so how could human power contend with it?

When the compilation work began, there was thunder outside the house and wailing everywhere inside the house. What was even more infuriating was that it was impossible for ordinary pens to draw the patterns of the demon race.

To solve this problem, Bai Ze cut his palm into a pen holder and shaved his hair into a pen tip. With the help of the dynasty's luck at the time, he once again forged a new national treasure, the 'Bai Ze Pen', and the ancestor of the Gu family personally painted the "Bai Ze Spirit Picture".

Forty-nine days later, the plot was completed, but the people died. In order to commend the achievements of the Gu family's ancestors, the Emperor bestowed this national treasure on the descendants of the Gu family. From then on, only the blood of the Gu family could drive this national treasure! "

To be honest, Gu Xuanyan's storytelling ability is obviously not as good as the storytellers in the teahouse. If she plans to work in this field in the future, Zhang San probably won't go to support her.

Fortunately, the logic is clear enough, and combined with the memories of other worlds, Zhang San can understand it (the alias named Qin Chi made up for a lot of lessons after traveling through time. Books like Taoist Canon and Shanhai are almost all in Zhang San’s memory palace).

Now he kind of understood why Gu Xuanyan, at such a young age, had already ended up with weak blood and energy. With a life-saving weapon like the Bai Ze Pen in hand, who could resist?

You know, if the secret painting school has enough cultivation, then it is possible to turn the virtual into the real. The status of the strange beasts from the mountains and seas is too high, and Gu Xuanyan probably won't be able to do it in this lifetime, but ordinary gold, silver, copper and iron are obviously not included in this category.

Now do you understand what level of rich woman the person opposite you is?

But what puzzled Zhang San was that although Gu Xuanyan said so much, she still did not explain why she went north to live with her relatives. It was obvious that this was the key point of the matter.

As if she sensed Zhang San's doubts, Gu Xuanyan first covered the corners of her mouth and pretended to sob, and used her sleeves to block Zhang San's sight. After calming down a little, she spoke again.

“Unlike other sects, the fighting power of the Secret Painting Sect is extremely dependent on inheritance. In short, the more similar the object is to the one being copied, the stronger the power it can exert. It’s a pity that after the painting was completed, the ancestor passed away and was unable to leave any inheritance to the Gu family.

The Human Emperor remembered the contributions of the ancestors of the Gu family and allowed the younger generations of the Gu family to choose one item from the "Bai Ze Jingguai Tu" as an inheritance. This is the origin of the Xing Tian Tu. As for the previous python, it was completely drawn by me based on my imagination, so its power is naturally insufficient.

In addition, the ancestors of the Gu family continued to lose their Qi and blood in order to gain combat power, which resulted in the poor aptitude of the descendants. After my generation, I am even the only one who has the talent for Qi training. Under such conditions, if it were not for the Bai Ze Pen, the national treasure, my Gu family would have been wiped out long ago."

Hearing this, Zhang San suddenly had an idea in his mind, and then he asked.

"So the reason you traveled thousands of miles north to join your relatives this time is actually for the Bai Ze Jinggua Tu. Only by cooperating with it can the Gu family rise again. But will Da Jin allow you to do this?"

"Third brother is really smart. He can guess my little sister's intention with just a few words. However, what third brother doesn't know is that in the course of historical inheritance, the "Bai Ze Jingguai Tu" has been lost. What is in the hands of Da Jin now is just a fragment.

The Great Jin Dynasty has made it clear that no matter who finds the "Bai Ze Jingguai Tu", the Great Jin Dynasty will offer a price that no one can refuse. It won't lead to a division of land and a title of king, but promotion to a higher position is real. However, for the secret painting school, the "Bai Ze Jingguai Tu" will be useless if I take a look at it.

But Third Brother, it's different for you. As long as we cooperate, this treasure can be sold at twice the price. Why not do it?"
