Smack!
It took a full three seconds before Liu Zheng hit the ground.
He grimaced as he crawled up, his body looking like it had fallen apart.
But looking at the courier, he didn't seem to fare any better; the bike frame was shaking.
After catching his breath slightly, Liu Zheng kept running forward, and the courier quickly pedaled away.
About two hundred meters ahead, there was another row of treasure boxes.
Since they were all question marks, he just ran straight into the treasure box ahead of him.
The courier made the same choice.
The treasure box shattered, revealing a can of unknown fuel in Liu Zheng's hand.
The red canister was labeled with the letters "N₂O."
Liu Zheng knew N₂O, dinitrogen monoxide, also known colloquially as laughing gas.
The stuff had a slightly sweet taste, a mild anesthetic effect, and could induce laughter.
Some reckless youths used it as a low-budget addiction; Liu Zheng had even reported on it.
