As soon as he swallowed the seed, Kayden felt the mana in his body multiplying. It wasn't like the seed of the world tree, where the mana came from the seed. This time, the mana in his body seemed to be increasing on its own. In just a few seconds, the amount of mana reached a point where Kayden began to cultivate with only the mana coming from within.
The amount increased every second and he continued to absorb and circulate it. He didn't even have to fix anything. Right now, his foundation was perfect, at least as far as his knowledge could see. Therefore, just by circulating mana, it didn't take long for him to be close to reaching the ideal point to advance.
In just a few seconds, Kayden felt himself within momentum, a kind of nirvana where anything could be possible and his movements were error-free. Kayden, once again, sought to improve his veins and his heart as he saw fit. It didn't even take him 20 minutes and he was done.
