All in all, killing a Gold-grade Boss had given him decent rewards. First, he had obtained a large amount of EXP. Currently, Li Cheng needed to upgrade his own level by leveling up most of his troops. The difference in strength between them was massive.
Moreover, the Shadow World was a special map. There were level one trash monsters and many Mythical-grade monsters here. Hence, Li Cheng planned to level up all of his troops to their maximum levels.
The Frost Dragons, in particular, required a lot of EXP to level up. Just one Frost Dragon alone required more EXP than all of a normal Lord's troops.
Apart from EXP and contribution points, what surprised Li Cheng the most was that his shadow points could also be amplified 10,000 times. One had to know that for such a large-scale event, his points could also be exchanged for many top-tier equipment and troops.
