"Damn it, did every reward have to be this over-the-top?"
Li Su pressed a hand to his brow. Three days had passed since the World Fragment reward, yet intense, unrelenting pain still throbbed within it.
Naturally, where there were drawbacks, there were benefits as well.

The second benefit was that, once this excessively violent energy had been absorbed, digested, and transformed into his world's energy, it made his mana extraordinarily domineering. With the same quantity, its power far surpassed what it had been before.
