After returning again, Shenli then spoke to them "Han Yu ri, Kang Su Rin, Jin Su Ri you guys went to the skill room with Kim Ji Sun, Park Moon Ji, I will go to the cultivation room first". Shenli decided not to talk to them much, she wanted to build friendships slowly through many obstacles.

They all felt a little strange, and then they left separately. Shenli walked towards the cultivation room, then she entered it. after entering it turned out that the room was empty, and there was only a box that read "enter coins here".

Shenli then took her coin and put 100 GM coins in, and suddenly an energy ran through the room.

Seeing the energy flowing suddenly Shenli realized that the energy was gas, he sat cross-legged and thought. "The angel said that there are 3 steps to building a body, Vein Building, Boiling Blood, Hardening Core".

She then thought of the correct arrangement regarding building a cultivator's body.

"So the first thing I have to do is Hardening Core, Boiling Blood, then the last is Vein Building".

Shenli closed her eyes and focused on being able to absorb energy, before long Shenli could feel a thin layer of tiny balls under her navel, realizing that Shenli said in her own heart, "This little ball is like 'Dantian' in novel stories, this is the core of power or energy storage, but this is still in the form of a shell".

"This is great, when I focus myself, an energy suddenly I can feel ''. Shenli's amazed face was beautiful to look at.

She enthusiastically started again. She concentrated energy that she could previously feel again.

Shenli slowly absorbs energy and forms it in the core. it absorbs for 2 hours and only forms a transparent ball, it contains energy, it's just still thin. Shenli is still concentrating and absorbing diving energy for hours. slowly the core fills up.

The energy is neatly formed and arranged by Shenli, if she doesn't focus just once, all of that can be messy and cause chaos in the Energy Core. But if it succeeds in uniting with Energy Core it will continue to stick without leaving.

The core grew thicker and finally revealed a visible layer of energy, not long after, "booommm" a energy around the shenli crashed, and shenli opened her eyes, finally, the core was successfully made, then she felt hungry.

"How long has it been," Shenli looked around asking herself.

"My stomach is very cryng, because I feel hungry. Maybe it's been more than 12 hours". '' She then thought, what would she do next.

"I'll be here in 2 days", then shenli fills that box with 200 GM coins,

Shenli opened the ring again and took a packet of food containing meat, and a bottle of drinking water, then she finished her meal.

It turned out that the time spent by Shenli was more than 20 hours.

"So troublesome, just a little mistake, if not I put it on slowly, I have to repeat it again. In this Core Energy". Shenli recalled how she felt before.

"In Dantian there is a small space, energy must be inputted to stay there. That small space is a very small point, because it is very difficult to feel it. I have to concentrate very much, if not, I can't feel it at all. And when I can feel it, the speed of energy absorption is twice as fast ". Shenli thought silently.

"Fortunately, when I can feel it, I do not lose control when absorbing energy. It should be released because my concentration is divided, but apparently not".

Shenli's face tried to remember something.

"I felt one small space, then I tried to feel another, I managed to feel the other, then it became more and more until I could feel everything. I should have lost control, while trying to feel another space, because of the same case, namely the concentration is divided, but why not".

Shenli thought "is it because my brain has kept it in my mind, or indeed that is the nature of dantian".

Not knowing what was right, Shenli continued what she was doing earlier.

"When the Energy core is empty, point by point the energy appears, then finally becomes thick. Then my Energy Core is fully charged."

Shenli closed her eyes, and when she tried to feel the Energy Core, She easily felt hundreds of small spaces.

Shenli opened her eyes, Her face showed surprise. "this is how it works".

"Is that possible?" she remembered her own words, 'the brain keeps them in mind. "Wow, this is amazing".

Then Shenli eagerly wrote down everything she knew and compiled it as the Cultivation Base for the Energy Core section.

The question arises in Shenli's mind "At that time I did not try to absorb energy at all, but why does it seem to flow in by itself, is this really the nature of energy or is it the nature of Core".

With a sweet smile, she wrote it as the nature of Core.

Shenli continued to build the body of a cultivator

.

"After forming the core I have to build veins, but how, do I have to make them myself, or do I have to adjust to the natural veins of the body"

After a few minutes of thinking, Shenli finally chose to adjust to the body's natural veins.

"This is better than making your own path which can be troublesome, I'm afraid to disturb this vein or make it destroyed. But if you follow the existing path, I'm sure it will be very safe."

After thinking for a while he said "I'll just give it a try".
