After I gather many data for my research, I draw a conclusion that the theoretical limit of Qi gathering stage is in the thirteenth level. Even so, breakthroughs after the tenth level still hard to achieve if a cultivator doesn't fulfill the necessary requirements.

At Qi gathering stage from the first level to the tenth level, cultivators can attempt their breakthrough brainlessly. However, that's not the case from the eleventh level upwards.

A cultivator needs a deep comprehension of his own body. There are nearly a hundred steps just for a breakthrough to the eleventh level alone, and every wrong step will create a backlash that will last for months.

If I'm not a doctor, I won't dare to attempt this process. I will start thinking of another way to get stronger.

At this moment I somewhat feel grateful for those shitty people in my previous life that make me walk in the path of medicine. Well, scratch that, even if hell froze, I still won't forgive them.

Anyway, I can feel a qualitative change inside my body after the breakthrough to the eleventh level. My Dantian -- a sea of Qi inside my body became purer after each cycle. This Dantian is like the quality of cement for a house. If it is good enough, it will allow for boundless future progress.

People often confuse Dantian with talent, but they are different. Dantian is always pure when someone born, but it becomes more impure as they grow older or gathering impure Qi. Talents on the other hands -- are something that won't change since birth.

Usually, Cultivator can't refine and make their Dantian purer than before -- but I can. This eleventh level is quite special, it where cultivators can start purifying their Dantian. If cultivators didn't reach this level before their breakthrough to Foundation establishment, their future potential will be diminishing as they grow older.

With just the fact that I can purify my Dantian, I can be sure -- there no one in my generations that have higher potential than me.

"Atchoo."

"Are you okay big brother?" after hearing a sneeze, a girl asks worriedly to a boy who pushes her wheelchair.

"It's okay Ven, only a little cold," he says with a smile after hearing his little sister concern.

"Is it because you swimming while protecting me, brother?" a little trace of guilt appear on her face.

"Of course not, this is just -- you know, probably someone talking about me," he put up a smile even when knowing his little sister can't see him.

After she hears a random excuse from him, she becomes more unsettled with his well being. She furrows her eyebrows and says, "Brother, I hope we can go to some rest area for a while before we continue our travels."

He knows that his sisters already see through his lies, he sighed, "Okay, we will search for an eatery along the way."

They still in a lush forest filled with big trees rise to the sky, there are no shops wherever he looks. Fortunately, this place has a little pathway from stone, he doesn't need to use his sword to cut any tree again.

The song of birds -- the pleasant background music, flowing to his ears while he's pushing his sister wheelchair, a thought appears in his head, 'Walking together in this tranquil place isn't bad too.'

"I know right, these calm melodies are very relaxing."

"Can't agree with you more, Ven."

They walk while listening to natural melodies and smelling the flowers scent. He's describing strange flowers to his sister while walking. Time passes slowly, but if you with your loved ones, it will be the most pleasant thing.

After nearly half hours, they found a little marketplace.

He searches an inn around them for their rest place today. While walking in this quite busy marketplace. There many shouting from every stand, the sellers want to sell their goods.

"Fresh fish, fresh fish. Brother, you won't regret buying this, my fishes are the tastiest fish in this island," a man's shouting to him when he walks in front of a fish stall.

"No thanks," with a smile he rejects the man offer.

Every area he walks there always many boisterous sellers or people who are just talking loudly inside a food stall. They're usually gossiping about unimportant things, but that just what people in this small island like, walk on a leisure life without worry about conflict of power like big clans.

After looking at a food stall, he asks his sister, "Do you want to eat first before we search an inn?"

"Um, I remember big brother isn't eating yet."

He goes to inside that stall with her sisters and ordering many foods on the menu. He usually eats just to recover his energy. However, after he tastes a spoon of the food, he feels as if covered by mother embrace -- comfortable warm feelings are surging inside his body. These are delicacies that don't even exist on the main continent.

'Sometimes there are unexpected skilled people hiding in a small pace."

After that, he continues eating at full speed.

"Uncle, another plate," with a full spirit he orders another plate.

"What, again?" the stall owners shock expression can be seen on his face. He just cooks another big pot of stew and that's eaten in mere minutes by this little boy.

The amount of foods and the speeds he eats is unbelievable, the stall owner can't even catch his breath when looking at his eating rate. If he's not paying first, maybe he will kick him already.

"There's no more uncle?" the boy asks again when looking at stall owners expression.

After hearing the boy question, he awakes from his shock and pulls his sleeve, "Okay kiddo, don't underestimate this old man, let me show you the chef ability on this island."

Unnamed stall owner: Looking at the satisfied expression of my customer after eating my foods.
