Right-click the rice bell in the vertical column on the left, and a menu will appear. Select Copy as a new record? Become ... "

Pop-up dialog box, modify English name, and click OK.

Choosing a DLC, I chose the armory of the arms dealer. Then find it in the arms of the arms dealer and modify the amount of ammunition.

The new dinner bell should be bought from an arms dealer. But I didn't open the game to find it, so be a mouse, brother. . .

Remember to tell me the result.
