Hearing the sound, Su Ya knew she had guessed right. When she came in, she felt that some of the toys there were rather strange, especially the miniature globe.

It just feels a bit out of place there; something like that shouldn't be there.

Ye Qinchuan, who was still searching for the mechanism in the storage room, did not expect that Su Ya had actually guessed correctly.

This really is a hidden door.

Suya returned to the storage room.

He was about to step forward and open the hidden door to go inside.

At this moment, Ye Qinchuan grabbed Su Ya's hand, stood in front of her, and said, "I don't know what's going on up ahead, you stay behind me."

Su Ya laughed when she heard Ye Qinchuan's words. She really wasn't afraid of anything. But since Ye Qinchuan said so, she would just do as he said.

Su Ya, unusually, did not refute Ye Qinchuan.

She let him hold her hand.

Looking through the hidden door, there is a passageway, not very wide, just enough for one to turn around.

If the hidden door is closed, it will be pitch black inside, and you won't be able to see anything.

Those two are incredibly bold.

Let alone a pitch-black passage, they've even ventured into ancient tombs, so how could they be afraid of this?

Ye Qinchuan and Su Ya didn't turn on their phone lights, since they didn't know where this passage would lead. If it was the bad guys' headquarters, they didn't want to alert them.

After Ye Qinchuan pulled Su Ya inside, the hidden door closed automatically, and the surroundings immediately became dark, so dark that you couldn't see your hand in front of your face. Su Ya touched both sides with her hands and felt that they were uneven and bumpy. There was also a faint smell of mud coming from the place.

Suya had read some history about China and was certain that this was the legendary tunnel, which was used to escape the chaos of war.

Su Ya recalled carefully, and if she remembered correctly, the family building of this medical research institute should be quite old, probably built during the Republic of China period.

After the founding of the People's Republic of China, this place should have been sealed off. You can tell by looking at that hidden door; it must have been discovered later, as the hidden door was clearly opened afterward.

Who discovered this secret door? What lies at the end of this passage? Su Ya felt a little excited. Perhaps she had been living a peaceful life for too long and had become somewhat numb, so she wanted to try something exciting.

Ye Qinchuan was in front, and Su Ya followed closely behind.

The passageway wasn't straight; it turned left and right at times.

Even with her excellent memory, Ren Suya eventually became confused. She wondered what the people who built the passage were thinking. Apart from making her dizzy, she didn't see anything good about it. There wasn't even a fork in the road. If someone followed her in, there would be nowhere to run.

The squeaking of mice could be heard from time to time, and sometimes you could feel something soft under your feet.

Luckily it was Su Ya; if it were any other girl, she would have been screaming and yelling by now.

Ye Qinchuan and Su Ya didn't know how long they had walked in this pitch-black passage.

Finally, we could see a faint glimmer of light coming through from ahead.

Su Ya and Ye Qinchuan were somewhat excited, finally they didn't have to walk in the dark anymore.

Although I'm not afraid, walking in the dark all the time can make me feel very depressed.

Su Ya was caught off guard and tripped, then fell onto Ye Qinchuan's back.

Fortunately, Ye Qinchuan sensed something was wrong and suddenly turned around, only to see Su Ya rush straight into his arms.

Ye Qinchuan groaned from the impact, but thankfully the sound wasn't loud. Su Ya instinctively covered Ye Qinchuan's mouth with her hand to prevent him from shouting again.

Su Ya's collision was extremely painful. Ye Qinchuan didn't know where Su Ya, a seemingly weak woman, got such strength. He felt like he was about to die on the spot.

Ye Qinchuan said Su Ya was a weak woman, but he really underestimated her. You should know that Su Ya was the kind of person who could break a table leg in half back then.

Su Ya asked softly, "Are you alright?"

Ye Qinchuan shook his head.

Actually, he was in so much pain that he couldn't speak.

When Ye Qinchuan turned around, he quickly touched the spot where Su Ya had bumped into him, feeling as if his ribs were about to break.

They stood there, trying to see if anyone would emerge from the light. Neither of them knew whether the person there was an enemy or a friend.

After waiting for a long time, no one came out.

So Ye Qinchuan decided to go and see for himself what was going on.

He whispered to Su Ya, "Ya Ya, I'll go in first. If you hear fighting inside, run back immediately. If not, then come in."

Su Ya didn't want Ye Qinchuan to protect her, so she disagreed and insisted that the two of them go in together.

"Ya Ya, be a good girl."

Ye Qinchuan looked at Su Ya gently in the dim light and said.

In fact, Su Ya knew that this was the wisest choice. If she didn't know if there was any danger ahead, it would be best for one person to go and the other to stay behind. In case of any situation, they could call for help. If both of them were in danger, then it would be troublesome.

But she is Su Ya; when has she ever asked anyone to protect her? She's always the one protecting others.

This was the first time someone wanted to protect her, and Su Ya felt good about it. So she tugged at Ye Qinchuan's sleeve and whispered, "Be careful."

Ye Qinchuan patted Su Ya's hand, then continued walking forward alone.

After waiting for a long time, Su Ya did not hear any sounds of fighting coming from the front, nor did she see Ye Qinchuan come out from inside.

Suya was a little worried.

So I decided to go and see what was going on.

She took out the gold needles and held them between her fingers, so that she could take immediate action to control the other party should anything happen.

Suya is very fast; taking down seven or eight people by herself is no problem.

She walked slowly forward, trying not to make a sound. When she reached the place where the light was coming from, she saw a small two-story building standing there, and the light was coming from inside the building.

Su Ya cautiously walked to the door, and just as she was about to push it open, she heard an angry male voice inside say, "Xiao Ye, what did you just say? Professor Hu was arrested? When did this happen?"

Xiao Ye, it seems Ye Qinchuan is out of danger.

Su Ya pushed the door open and saw Ye Qinchuan sitting in the middle of the room, with six people who had disappeared for more than a week sitting next to him.

When Su Ya was researching before, she saw photos of these people and memorized them. These people were Professor Hai Qing, Professor Ming Yuan, Professor You Dequan, Professor Hong Song, Director Li Ran, and Director Xie Zhongqing.

Su Ya had a question in her mind: Could it be that the professor hadn't disappeared, but had instead hidden himself away?
