"—what should I choose? All three items are good and can improve my cultivation except the purification pill can improve my cultivation speed"

thinking about the pros and cons  of the items that appeared in the list on the system screen, and after a while thinking he finally made his decision

"—the purification pill does not increase my cultivation level directly and pure mana pill is not sure to increase my cultivation as the pure mana crystal according to the description of the system directly increases the cultivation, so I will take the Crystal of mana" having decided to take the pure mana Crystal

[Congratulations on purchasing the pure mana crystal]

so the notification appeared before André's eyes, a very small white crystal that fit in a baby's palm and shaped like a diamond and the crystal glowed in a white light, 

" — it's really small, but how do I do it? the system promptly answered the question

[eating and used its cultivation technique]

having heard the system's answer Andre was apprehensive because it was something strange and bright "—and is this safe?" and then came the answer

[the mana crystals are made exclusively of mana]

Even listening to the system's response, André still didn't eat the crystal, he kept staring at the crystal looking for something that might cause him a problem, after a few seconds and found nothing,

"—it seems like there's nothing dangerous with these crystals" 

then he he took the Crystal in his mouth and swallowed it, inside André's stomach the crystal dissolved and thus released his mana throughout André's body and energizing cell by cell, sensing the energy flow through his body André started using the breath of serpent to guide this mana to its Magic core and convert it into poison and darkness attribute.

The whole process ended after an hour,  after finishing absorbing the mana from the mana crystal, André noticed that the amount of mana in his Magic core had increased a little so he went to check on his status screen

"—I just climbed three levels, but not only that I can feel my body is stronger" 

having these thoughts  André went to a rock wall at the back of the cave, looking at the wall he raised his tail and hit the wall (bam) a loud sound was heard on impact,

"—my good lady!" Andrew said this amazed seeing a deep mark on the wall in the shape of its tail, "I'm almost as strong as that wolf" seeing that mark on the wall notices something strange

"—wait, isn't that mark too big?" he said this because the brand in question is almost 1 meter long, so André notices that his body has gotten bigger at 2 meters long and with the thickness of a grown man's leg.
