In a hurry, Lin Cheng walked quickly, and in less than a minute following behind Cola, he rushed to a small room located in the southeast corner of the first floor of the research institute, which looked very hidden.

"You're back?"

As soon as he entered the door, before Lin Cheng could take a closer look, he saw Lin Yongjian, who had a dusty face for some reason, walking towards him with excitement on his face.

"Well, what did you find?"

Nodding, Lin Cheng glanced left and right around the layout of the room, and then asked him.

"You come with me!"

Hearing this, Lin Yongjian beckoned to him, then turned around and walked to the left corner.

"Look at this."

After walking to the corner, Lin Yongjian suddenly pointed to the wall in front of him and said.

Following Lin Yongjian's fingers, Lin Cheng narrowed his eyes slightly and carefully observed the inconspicuous wall in front of him.

After a few glances left and right, Lin Cheng didn't see anything abnormal, but since Lin Yongjian said that there was a problem with this wall, it was definitely a problem, otherwise he wouldn't have asked Coke to find him back so confidently.

"Huh?!"

Observing along the right side of the wall again, Lin Cheng suddenly frowned when he swept to a position about the height of his wrist!

"This trace...... Did you just move? ”

Squatting down, Lin Cheng carefully observed the inconspicuous scratch in front of him for a while, and then raised his head and asked Lin Yongjian.

Hearing Lin Cheng's inquiry, Lin Yongjian nodded lightly and explained, "Yes...... Because Coke and I searched almost the entire first floor and couldn't find any deliberate entrances and exits, I had no choice but to use a fruit knife to scratch all the possible locations of the door, and I found this place. ”

"Awesome!"

Seeing that this guy had carefully slashed the gaps in the walls of all the rooms on the first floor with a fruit knife in order to find the exit, Lin Cheng was immediately impressed by him, and secretly said in his heart that this guy looked wilted on the surface, but he was also very desperate when he was serious......

Standing up and taking two steps back, Lin Cheng glanced at the wall in front of him once again with the notch he had just seen, and then found that the outline of an extremely inconspicuous door suddenly appeared in front of him!

"Hmm......"

Looking at the outline of this door hidden in the wall, Lin Cheng suddenly felt a little troubled, the room where this door was located was already very remote, and it was hidden in the wall, so it was basically certain that behind the door should be the shelter where those research institute staff were hiding.

But the problem is that he suddenly doesn't know what to do now, since it is the gate of the shelter, especially if he has a military background, I am afraid that ordinary violent methods will not be able to cause any damage to this door at all, and he himself does not want to make too much movement, since these people can build a shelter to resist the arrival of the end before the end of the world, then the defense level will naturally not be low, if he appears rashly, those researchers are not his opponents, But if he couldn't control everyone at once, he was worried that the experimental materials that he valued so much would be destroyed on the spot by the researchers who felt that he was cornered!

"What's wrong?"

Seeing that Lin Cheng's expression was a little wrong, Lin Yongjian couldn't help but ask in a low voice.

"Nothing."

Shaking his head, Lin Cheng frowned and glanced up and down the door of this shelter a few times, and then said, "It's just that I think this door doesn't seem to be so easy to break...... And even if it can be broken, the noise is almost enough for the people inside to react, and then it's time to destroy the data, destroy the data, it's time to run away, right? ”
