For the following days, Su Yu stayed within the Mage Tower, absorbing the materials of magical beasts to increase his strength.
Next to the Mana Pool, little Kathy diligently moved back and forth between the pool and the stack of material, following Su Yu's instructions and throwing batches of material into the pool.
As the pool refined the materials, an endless stream of purified mana gathered around Su Yu. One wave after another washed over him, rapidly elevating his strength.
His game log also started in "crazy scrolling" mode:
"Ding, by absorbing purified mana, you gain 1000 Experience Points!"
"Ding, by absorbing purified mana, you gain 1000 Experience Points!"
"Ding, your level has reached 38."
.....
"Ding, your level has reached 39."
...
"Ding, your level has reached 40."
...
Finally, after refining materials for two and a half days, Su Yu successfully reached level 50 and became a third-rank Mage!
