At the beginning, he crossed over to become the cannon fodder villain's father

Afterwards, Zhao Chengfeng also came to the living room immediately. As expected, it was Song Yijin who came back. At this moment, with a blank expression on his face, he casually threw his briefcase on the sofa and sat down on it.

As for Zhao Chengfeng, since he was still in a state of invisibility, he stood not far from Song Yijin and looked at him, so no one would notice him.

At this time, Zhao Chengfeng suddenly saw a wicked smile on Song Yijin's face, and his eyes became very strange.

The amiable Mr. Song in the daytime disappeared at this moment, as if he had changed in an instant, Zhao Chengfeng was also taken aback.

This guy really has a problem, as can be seen from his expression alone.

Then, as if he suddenly thought of something, he slowly got up and walked to the basement, opened the door of the basement and walked in.

When Zhao Chengfeng saw this scene, he immediately felt that there was some secret hidden in the basement. Otherwise, why would Song Yijin go to the basement the first thing he did when he came back?

So Zhao Chengfeng immediately followed and entered the basement behind Song Yijin.

After entering, Zhao Chengfeng was stunned. It turns out that this basement is not an ordinary underground space, but has been converted into a place where people can live.

Inside is a very large space, with a big bed in the middle, with quilts on it, and a whole set of incense making equipment next to it.

And Song Yijin, after he came in, had already started researching in front of that set of equipment, very seriously, without even realizing that Zhao Chengfeng was actually observing behind him.

When Zhao Chengfeng saw what Song Yijin was studying now, he couldn't tell what it was, so he decided to look around first.

Because now he wants to know who this Song Yijin lives with.

He walked to the bed. The quilt on it was pink, and there were two bedside tables beside it. The photos on it made Zhao Chengfeng's pupils shrink sharply.

Because this is actually Xu Qingqing's selfie, looking at that familiar face, Zhao Chengfeng was deeply moved.

Afterwards, Zhao Chengfeng also took a special look at the surrounding layout and the items here, and he found that most of them were used by Xu Qingqing.

What clothes, what shoes, and even Xu Qingqing's notebook and some notes on the table.

Now, Zhao Chengfeng can confirm that this basement should belong to Xu Qingqing's room.

In that case, wouldn't it mean that the year and a half when Xu Qingqing disappeared was spent here, no wonder the outside world didn't have any records of Xu Qingqing's year and a half.

In such a place, as long as Xu Qingqing doesn't take the initiative to go out to show her face, other people will indeed find her existence very much.

Moreover, through the equipment Song Yijin is using in this room, Zhao Chengfeng can also guess that Xu Qingqing is probably doing research on spices during the one and a half years here.

Moreover, it is very likely that she conducted research and innovation under the guidance of Song Yijin, and finally researched those spices.

In this way, the relationship between Song Yijin and Xu Qingqing is a bit unclear.

If it was really just teachers and students, then why did Xu Qingqing live directly in Song Yijin's house?But if the two are lovers, why does Xu Qingqing only live in the basement?

But now these words are not important to Zhao Chengfeng.

As long as he can be sure that Xu Qingqing lived with Song Yijin for a year and a half when he disappeared, that's enough.

Suddenly, Zhao Chengfeng thought of something, Song Yijin is currently studying Xiangfang.

So he immediately walked over, wanting to see what kind of incense recipe Song Yijin was researching.

At this time, Song Yijin had reached the final stage of researching the fragrance recipe, and Zhao Chengfeng could see the specific ingredients and efficacy of this fragrance recipe.

He took a closer look, and the result can be said to be within his expectation, but also a little unexpected to him.

Because the incense prescription Song Yijin studied was a relatively complete version of the incense prescription that Xu Qingqing used to Xu Xiuya at that time.

According to the news that Zhao Chengfeng got now, it was obviously expected.

But what Zhao Chengfeng didn't expect was that this incense recipe, no matter in terms of raw materials or efficacy, seemed to be much higher than the one used by Xu Qingqing, and it was not of the same grade at all.

Moreover, the problem now is that Zhao Chengfeng doesn't know the pros and cons between Song Yijin and Xu Qingqing at all, and what kind of effect will the incense prescription Song Yijin put out now have?

So Zhao Chengfeng then began to carefully look at the incense recipe that Song Yijin was researching, wanting to see what the secret was.

After a while, Song Yijin also finished making the incense recipe, with a smile on his face.

"Haha, it finally succeeded, Qingqing, you didn't expect that, did you? Actually, yours is not the final version!"

After making this incense recipe, Song Yi came in with a sentence that made Zhao Chengfeng a little confused.

What's happening here?Why does this guy feel like he has a conflict with Xu Qingqing?

Zhao Chengfeng thought to himself.

But in the next second, Song Yijin walked up to a curtain and pulled it open, which made Zhao Chengfeng stunned.

And it also surprised him very much.

The curtain looked very heavy, so Song Yijin pulled it very slowly, and it took a lot of effort to pull the curtain completely open.

There is a wall behind, and this wall is actually covered with photos.

Zhao Chengfeng went up to have a look, and was startled.

Because these photos are actually Xu Xiuya's.

There are not only some photos of Xu Xiuya's life on it, but also stills of the characters played by Xu Xiuya. In short, judging from the number, it is estimated that there are hundreds of photos, large and small, posted on it.

Zhao Chengfeng was stunned, what was going on with this guy, why did he post so many pictures of Xu Xiuya.

Or are these photos actually posted by Xu Qingqing?After all, Xu Qingqing attacked Xu Xiuya.

Moreover, Zhao Chengfeng had a more bloody guess.

He thought it might be that Xu Qingqing liked Song Yijin, but what Song Yijin said was interesting to Xu Xiuya, so wouldn't Xu Xiuya become Xu Qingqing's biggest rival in love?
That's why Xu Qingqing attacked Xu Xiuya.
