C429 The Pickled Vegetables Pot

Lu Shan once again upgraded his Upgrade Box.

This Upgrade Box also had a level. As his character level increased, it also increased. Furthermore, the number of times the Upgrade Box could be used in each level was limited. If the Upgrade Box was not leveled up, then, he could only use it a few times.

Of course... the synthesis of materials could still be used. It could be used five times a day
