All the nodes of the shaped charge gun are full, then put on the clothes added by the shaped charge gun, and finally, BOSS, put down 6 guns. The node-full shaped charge gun 1 sec is basically full, and the mob directly blows it up with one shot, generating resources and cooperating with the static force field full of clothes. In a static force field, the little BOSS can put down three shots without injury. The most important thing is that the static force field is triggered within the melee range of the auxiliary fire group of the shaped charge gun, which is equal to the extra static force field, reducing the use pressure of the static force field of clothes. As long as the shooting accuracy is a little, combined with the static force field, the shaped charge gun can take you through without injury, without considering the ammunition problem at all.

Upgrading means moving from a lower level to a higher level. Not demoted.
