If it is lost, one would need to go to the grocery store to report the loss, pay a credibility penalty, and until the Contract Gun is bound again, the players can only then start using Grass Baby Coins.
For players who have gradually used Grass Baby Coins as daily settlement currency, they are now absolutely dependent on Grass Baby Coins, hence the constraints of the Contract Gun on them are still very strong.
Becoming blacklisted by the grocery store for the sake of a gun, and even having the account canceled and Grass Baby Coins entirely offset is not a worthwhile deal for most players.
Unless truly resigned to a fatal outcome, no player would do that.
However, even Yu Liang, who is considerate of players, has his own considerations. He must be prepared for players' accidental deaths within the Copy, which every accidental death could lead to the loss of firearms and results in losses for the Yu Clan Group.
