The one who triggered the explosives was Lu Fan, and since Tang Zheng wasn't a god, there was no way he could have perfectly sniped the pursuing Scorpion while also focusing on making an escape route.
Tang Zheng immediately activated all scanning systems attached to the Hellfire, but the sudden influx of data on the screen almost blinded him. He quickly turned them off, keeping only the infrared scanning and night vision equipment. The two powerful beams of light illuminated a 160-degree fan-shaped area in front of him, enough for him to see everything in the dark.
Of course, now Tang Zheng stood out like a lighthouse in the dark ocean, the ghouls wouldn't need to search, they could just rush towards the light. Thus, along the path Tang Zheng ran, hundreds of corpses were left behind. He wanted to attract their offensive.
