After Gu Changjing came back from Cheng Mansion, he thought of Cheng Shuting's attitude just now, and felt that this matter was somewhat wrong, and at this time, when he saw Shen Yanjun and Cheng Shuqi still here, he remembered that he had forgotten to go to the Prime Minister's Mansion.

Fortunately, it didn't take long for Shen Yanjun to wake up.

"Well, have you investigated anything?"

The first thing Shen Yanjun said when she woke up was to ask Gu Changjing about the investigation of the case.

"As you think, this matter has something to do with these texts after all."

When Shen Yanjun heard this, she also nodded.

"Are you going to my grandfather's house?"

When Cheng Shuqi heard this, he only felt a little strange.

"Sister Jun, what does this matter have to do with my grandfather?"

"Silly girl, the four treasures of the study room to be used in the imperial examination are all prepared by the Cheng family, you say, does it matter?"

Cheng Shuqi nodded suddenly at this time.

Gu Changjing saw that Cheng Shuqi was still here, and he was embarrassed to say some questions about the Cheng family.

Shen Yanjun saw Gu Changjing's face and immediately understood.

"Xiaoqi, I just woke up and felt a little dizzy, can you go to the shop outside to buy two mints for me."

When Cheng Shuqi heard this, he didn't have too many doubts, nodded and ran out.

"Okay, if there is anything, you can just say it, these shops outside don't sell this thing, Xiaoqi's kung fu with a pillar of incense can't come back."

Gu Changjing nodded.

"Your grandfather's house, I've already been there, I speculate that this matter doesn't have much to do with Su Guogong, but your cousin's behavior is a little strange."

So, Gu Changjing also told Shen Yanjun what he had just investigated, and Shen Yanjun felt that Cheng Shuting was a good person, and there should be no such thing.

Presumably, there is another hidden truth in this matter.

"Can you still find the paper you used for last year's exams this year? We only need to compare the materials used twice, and everything will be clear? ”

Hearing this, Gu Changjing also nodded.

"I'll do it right away."

With that, he walked out.

When Cheng Shuqi came back, he found that Gu Changjing had left with the scriptures, and he should feel a little stunned.

"Sister Jun'er, here you go."

Cheng Shuqi's well-behaved appearance made Shen Yanjun feel a little embarrassed to lie to him.

"Okay, okay, I'm fine now, let's go back first."

Cheng Shuqi nodded, and the two went back to the Prime Minister's Mansion together.

Regarding what happened today, Shen Yanjun felt that she still had concerns in her heart.

If this matter really has something to do with my cousin, what should I do then?

Gu Changjing immediately arranged for someone to find the paper that had not been used up last year in the warehouse, and personally stared at these imperial doctors to check the ingredients inside.

As a result, this year's recipe is indeed very different from last year's.

The paper I used last year was made from the finest materials and was of high quality. But this year's materials are of inferior quality, and they look as thin as cicada wings.

Presumably, it is because of the difference in these materials that such consequences will be caused.

Gu Changjing knew this result, and thought that Cheng Shuting seemed to be a little wrong today, and he also had a little doubt in his heart.

It seems that it is still necessary for him to go to the Suguo Mansion again, and the answer to the question is hidden in Cheng Shuting's body.

Thinking like this, he didn't want to delay this matter any longer, after all, there are still many people in a coma, if they don't solve it quickly, I'm afraid these candidates won't give up so easily.

Cheng Shuting was not at home at the moment, Gu Changjing took the paper used in the past two years and came to the door.

"Guogong, I used this year's paper and last year's paper to make a comparison, and found that the materials used in the two years are indeed a little different, why don't you take a look for yourself!"

When Su Guogong heard this, he took the thing in his hand and weighed it.

I found that things in the past two years are indeed a little different.

What's going on here? No one knows.

"Although we haven't noticed it yet, why is it so poisoned, but I still hope that you can find the young master to ask about this matter, otherwise this matter may bring a lot of trouble to the Cheng family, and I don't need to say more about the consequences."

Su Guogong has always been a smart person, and naturally understands this matter, if it is discovered, how big a blow it will be to himself.

Gu Changjing obeyed the emperor's arrangement and saved enough face for this old man, so he didn't say anything, but he just wanted to wait until Cheng Shuting came back later, and then continue to ask him about the causes and consequences of this matter.

Su Guogong knew in his heart that if Gu Changjing was here, Cheng Shuting would definitely not tell the true situation of this matter.

Therefore, he could only ask him to wait behind the screen, and then ask him what was going on.

Sure enough, it didn't take long for Cheng Shuting to finish dealing with what happened outside, and he would come back later, and when he saw the serious look on his grandfather's face, he felt a little weak for a moment.

"Ting'er, there is no one else now, you tell grandpa what happened."

Cheng Shuting heard Su Guogong ask this, thinking that he already knew the cause and effect of this matter, and knelt down in an instant.

"Grandpa, you save me, I really didn't mean to."

Cheng Shuting said this, Su Guogong only felt that his heart was already cold, it seems that this matter is indeed inseparable from his grandson.

"What the hell is going on? As long as you tell the truth, I will be able to help you. ”

Cheng Shuting had no choice but to tell his grandfather that he had lost money in the casino, and there was no way but to make a little money to pay off the debt in this way.

When Su Guogong heard this, he was almost angry.

He didn't expect that his grandson, who he had cultivated since he was a child, would be so ignorant, and when such a thing happened, he only felt that his heart was full of shame.

"Grandpa, save me, if it weren't for helplessness, I wouldn't have done such a thing."

Cheng Shuting knelt down, but Su Guogong knew that Gu Changjing would never let it go.

At this time, he also walked out from behind the screen.

"His Royal Highness King Qi, the cause and effect of the matter, he has already said it just now, how to deal with it? See for yourself! ”

Su Guogong didn't want to speak for his grandson at all, he only felt that what happened was the reason why he didn't teach well.

"The prince is serious, how to deal with it, we still need the eldest prince to cooperate with us, and I will tell the emperor about this matter when the time comes, and I can't make the decision about the next thing."

The moment Cheng Shuting saw Gu Changjing, he only felt that his heart was full of despair, it seemed that if he wanted to get rid of this matter, it would never be so simple.
