Very soon, the wooden arm crossbow was assembled. Because this arm crossbow was for upgrading the assembled crossbow arrows, he didn't plan to upgrade it, lest he break his own crossbow arrows.
It is worth mentioning that the effective range of this arm crossbow is only about ten meters. Within ten meters in a straight line, it still packs some power, but when met with a harder target, it can't penetrate.
Even if the target is within eight meters, if the target is hard enough, it still can't penetrate.
As expected, the method to upgrade this assembled crossbow arrow is by shooting it out.
Shooting it out once grants one experience point.
In more than half an hour, this assembled crossbow arrow was upgraded to the marvelous level.
