This sound seemed to be a signal, and cracking sounds were heard one after another.
The tiles above his head fell even faster, falling to the ground. Some of them hit the edge of the pool covered with unknown plants, making a loud noise.
The laboratory had been abandoned for many years and had been invaded by mutated plants. It was already on the verge of collapse, and any slight movement at this time could lead to extremely bad consequences.
The cracks on the roof became even wider, and the ceiling above them creaked and shook.
This scene clearly showed that the laboratory was about to collapse.
Song Qingxin cursed. This laboratory had to be built at the right time. Now that the two of them had come in, they were already in trouble. They were really unlucky.
The cracked roof above her head began to collapse, and a large number of bricks fell down. In order to avoid being crushed by the collapsed building, song qingxiao had no choice but to retreat.
