After returning to Song's house, it was already ten o'clock in the evening.

Ye Chen walked to the door of the hall with Yun Yi, and heard Song Ya's voice from inside:

"Where did this beautiful little girl come from, you wait, I'm going to pass it on to Miaoyan!"

Ye Chen's heart instantly felt nervous, and then he hurriedly said with a hippie smile:

"This is my sister and the core of the Song Group's black powder. ”

"Black powder?"

Liu Qi also hurriedly walked out of the hall.

And Ye Chen observed that when Liu Qi saw Yun Yi, he had an incredible expression on his face.

In this regard, Ye Chen could only smile awkwardly.

After all......

Anyone who sees the core of technology is just a nineteen-year-old girl will feel a little surprised.

After Ye Chen explained, Liu Qi believed that Yunyi was a high-achieving student of science.

"I really didn't see it, I was really young and promising. ”

Liu Qi said lightly, and at the same time hurriedly let the two of them rest and arrange a place for Yunyi to live.

Lying on the bed, Ye Chen breathed a long sigh of relief.

Although it is only Yunyi's emotional problem, as an elder brother, Ye Chen is still very worried in his heart.

Yunyi has undoubted achievements in science.

But on the other hand, Yunyi is too simple to be deceived.

Thinking that this time, Yunyi was going to take an important position in Qi Yu's company, but he was actually a little worried in his heart.

The night passed.

As soon as Ye Chen got up, he came outside to box.

At this time, Song Ya also got up to go to the toilet, and saw Ye Chen boxing outside, and then turned her head.

For such scenes, Song Ya has become commonplace.

But in the next second, Song Ya turned her head violently.

The scar on Ye Chen's back is so shocking.

In an instant, Song Ya thought of when Ye Chen first came to Song's house, and she also saw the scar on Ye Chen's back.

And, Song Ya then thought of an incident when she was a child.

"Ye Chen. ”

"Huh?"

Ye Chen turned his head suspiciously, looking at Song Ya, whose hair was messy.

"You...... The scar on the back, what's going on?"

"Ah, this one, it's left over from fighting with others when I was a kid. ”

Ye Chen said lightly, and at the same time hurriedly put on his vest:

"Are you hungry, now that the meal is ready, hurry up and eat. ”

But Song Ya still looked at Ye Chen with a suspicious face, and the woman's intuition told Song Ya that Ye Chen was hiding from herself:

"Is it when I lived in the Song family before?"

Ye Chen rubbed his chin, and then nodded.

In an instant, Song Ya seemed to have returned to her childhood.

When Song Ya was a teenager, she was once attacked on the way home.

I don't know if it's because of the eldest daughter of the Song Group, Song Ya was suddenly pressed to the ground one night.

At that time, Song Ya had just finished tutoring, and she happened to be walking on a small road that no one patronized.

The little girl in her teenage years had no strength to fight back at all.

Song Ya cried in despair, but no one paid attention.

At this critical juncture, Song Ya suddenly felt that she had been put on the ground.

Looking back, two dark shadows were fighting.

Song Ya fell to the ground, an emaciated figure, fleeing in a hurry.

Judging from the figure, Song Ya decided at a glance that the man was a teenager.

Song Ya hurriedly wanted to escape, but at this moment, a cold color suddenly flashed in the afterglow.

Looking back, in the moonlight, the gangster drew his knife and was chasing the shorter-looking figure.

Song Ya was stunned in place, she was too young at the time, and Song Ya didn't know how to deal with this kind of emergency.

After a short hesitation, Song Ya immediately chose to escape.

But at this moment, I suddenly heard a scream behind me.

The emaciated teenager was stabbed in the back with a knife by the gangsters.

And it was from this moment that Song Ya ran forward with her life.

ran to a safe place, and Song Ya began to recall whether the boy who saved him was in danger of his life now.

After arriving home, Song Ya told her parents about the situation, and Song's father immediately chose to report the case.

At the same time, he also sent people to look for the teenager at that time.

But what is very suspicious is that neither the environment at the time nor the surveillance cameras have found the teenager.

And Song Ya's escape without looking back made her feel even more ashamed.

At this time, seeing the back behind Ye Chen, Song Ya felt a trace of surprise and curiosity.

Could it be ......

The young man who saved his life was Ye Chen?

And at that time, Song Ya still remembers that it was after Ye Chen ran away from home.

Song Ya glanced at Ye Chen in front of her, and then asked with a suspicious face:

"You ...... a few years ago Did you save a girl in a dark alley?"

"Huh?"

Ye Chen looked at Song Ya with a smile on his face, then smiled and asked:

"Isn't it...... When you were making out with your boyfriend before, you were caught in a dark alley?"

"Hey, I'm asking you about business!"

Song Ya slammed a small pink fist into Ye Chen's chest, and then asked with a serious face.

"Haha, no, you used to ...... Did something happen?"

Ye Chen's face changed instantly.

"It doesn't look like he's it. ”

Song Ya thought to herself in her heart, and at the same time glanced at Ye Chen in front of her, and then turned around in a dashing manner.

Looking at Song Ya's departing back, Ye Chen let out a long sigh of relief and walked to the dining table.

At this moment, Ye Chen saw the comic book next to the dining table again.

"That's right, the secret of my godfather hasn't been solved yet. ”

Ye Chen thought suspiciously, and at the same time picked up the comic book and began to flip through it.

But......

After reading it, Ye Chen still didn't find anything useful from it.

No matter how you look at it, it's no different from ordinary comic books.

After sitting for a while, all the other people woke up one after another.

Liu Qi woke up the latest, and when he saw Yun Yi sitting next to Ye Chen, he came over and briefly explained some information about Qi Yu and the Song Group.

To put it simply, the sooner you can research black powder, the more it will help you.

After Ye Chen heard it, the corners of his mouth just rose slightly.

As it stands, the direction of research is almost clear, and the rest is only a matter of time.

And the purity Ye Chen also gave an approximate range.

It is estimated that it will be solved in three days.

It is many days faster than the month given by Qi Yu.

"Estimated...... It can be solved in three days. ”

Yun Yi and Ye Chen's thoughts coincide.

Liu Qi laughed happily.

And at this moment, Ye Chen suddenly thought of the comic book.

Yunyi and Godfather, since they are both high-achieving students, they are also engaged in scientific research.

Will...... Is it a point in the book that was skipped by itself?

"Yunyi, come over here. ”

Ye Chen suddenly patted Yun Yi on the shoulder, and at the same time walked outside the hall.
