Playing the legend of Noah, there is not enough space in the backpack. What should I do? There are many Raul crystals in it, which take up space and second-hand equipment (very low-level). What should I do? There is not enough space in the backpack. You can put up to 99 drugs together. Raul crystal can't be sold and can't be used for equipment in the future. If there are more than two or three grades, you can choose crystal synthesis from the reformer to synthesize advanced crystals (generally three are combined into one). Above level 4, level 5 can be synthesized. This can save a lot of space. If the equipment is not upgraded, the low-level equipment can be sold with the high-level equipment. The equipment after the fourth gear and the fifth gear can be left to synthesize yellow equipment. If it really doesn't work, you can open a trumpet and put all the unbound things in it.
