Although Zhao Yu used the multifunction key awarded by the system to unlock the bicycle, and had also used the night vision device which he had recently received so that he was able to see in the dark, his mind was filled with regret and frustration. If he had not been so anxious just now, he could have used an invisible tracking device to locate Hou Meng’s location so that he would not have to worry about Hou Meng running away! However, due to the urgency of the situation just now, he had forgotten about this powerful tool! If he had been calm enough, he could have switched off the lights in the warehouse and used the night vision to sneak past those pyramid scammers and go after Hou Meng. This way, he would have been able to save a huge amount of time and energy, and he would not have to fight with those scammers!
