"Retractable poison thorn? Biological weapon? Is this what a biological weapon is?"
At the banquet earlier, Wang Tao mentioned that the barrier at Changhe Base was the functionality of a biological weapon. But Wang Tao didn't elaborate much, merely saying that the biological weapon was a towering tree.
Therefore, Tu Li and the others subconsciously thought that a biological weapon should be something akin to a monster, enormous in size. They hadn't considered that a biological weapon could be so small. That's why Tu Li's expression was a bit confused.

"Some monsters or zombies, before they die, they drop some things, which include biological weapons. And this retractable poison thorn is a Level 5 biological weapon. As for what a biological weapon is... as the name suggests, it is a type of weapon, except it's not made by humans, and using it requires consumption of Crystal Cores. But its power is much greater than that of ordinary weapons..."
