Outside that small factory building, there was a small courtyard, and at the entrance gate of the courtyard stood a person.
Su Chen recognized him right away—he was also a Gene Modifier.
Upon seeing Su Chen come alone, he immediately led Su Chen in with an expressionless face.
Once inside the factory, Su Chen first surveyed the layout inside; it was his instinctual habit.
He noticed that in the middle of the ground floor was a spacious cement area, flanked by two rows of rooms on both sides.
Next to this open space was a staircase leading to the second floor, which was surrounded by an iron railing that had already become rusty and obviously many years old.
The second floor also had a row of rooms, but unlike the layout on the first floor, they were arranged vertically, so Su Chen could clearly see every room's door.
At that moment, Su Chen didn't see a single person in his field of vision; he knew those people were definitely hidden in various rooms.
