The Twin-headed Snake had evolved into a Swamp Hydra.
A huge amount of mana had surged into his body, and it had allowed Locke to immediately advance from Stage 3 to Stage 4.
Nevertheless, Locke did not rest.
Level 1, Level 2, Level 3.
He continued to break through, and his mana capacity did not increase as violently as before. At the very least, Locke's appearance did not make any drastic changes.
To the observers outside, Locke was sitting quietly and guarding against possible dangers.
In truth, however, Locke was fully focused on his internal state.
With the sudden increase in his strength, all his muscles, bones, and tendons had to be adjusted accordingly.
Even his body had grown three inches taller.
The amount of pain caused by the stretching of his skin and tendons was excruciating.
However, Locke did not move at all. Even though the pain he felt was unbearable at times, he had only frowned at most.
