Luo Yirui led the youths running all the way up without stopping, knowing that a fierce battle was about to start below.
The reason they could proceed so smoothly was that when Grandpa Desan was leading Director Ma around, he received a communication from his father, telling him to wait for the signal, which would be the explosion on the roof.
Once the explosion occurred, he would immediately lead the youths to burst through the second level, at which point the electronic door would open for them.
Luo Yirui felt somewhat excited in his heart; his father had arrived at last!
While they were running up the stairs, intense gunfire sounded from below, making Luo Yirui feel a bit uneasy, worrying if his father and the others would be alright!
They rushed all the way to the outer building on the first floor before the youths stopped, gasping for breath. It wasn't the two flights of stairs that exhausted them, but the tension in their hearts.
