Yang Yi hurriedly followed Brian and Paul. When Brian noticed Yang Yi keeping up, he just frowned, but instead of stopping Yang Yi, he whispered, "Make it quick, don't slow us down."
They soon arrived underneath a window that was lit up. Brian looked up, assessed the situation, then signaled with his hand. Paul immediately crouched down and stretched out his hands. Brian took a few steps back, sprinted forward, stepped on Paul's outstretched hands, and then leapt up, grabbing the lower edge of the second-floor window.
However, after grabbing the edge, Brian tried to push up with his arms to secure his feet on the windowsill, but his hands slipped, and he fell down.
He landed on the ground, but fortunately, Brian was agile enough with his hands to avoid a nasty fall.
Rubbing his hands, Brian looked up at the window with a look of astonishment and said, "Fuck... "
Paul wanted to laugh but dared not to. He whispered, "Let me go up."
