She went through the cultivation book. There she got some more knowledge about how these cultivation worked.
Basically, the person must focus on his surrounding and try to sense the spiritual energy around him. Then guide those energy inside the body slowly.
'I should cultivate now' Su Yuxin thought.
She sat crisscrossed. Slowly inhaling and exhaling, she started focus on the surrounding trying to sense the energy.
Finally, after long time she could feel faint energy flowing through her meridians. She tried to keep the flow steady and balanced as much as possible.
As she looks at the flow of spiritual energy, she noticed that there were few different color energies trying to go inside her meridians. They were red and brown in color.
'That's unusual. I should ask grandpa about it.'
She let those energies enter inside her meridians guiding them along with the white spiritual energy.
Soon,
"Boom!"
' I broke through red warrior.'
She opened her eyes and looked at the sky. It's already night.
She went to eat her dinner and went back to cultivating. Cultivator don't need to sleep or eat.
Spiritual energy provides the body enough power to survive without them. The higher your cultivation level, longer you can survive without food and sleep.
The tranquility of the early morning was broken by the birds chirping. Su Yuxin was in the same position all night cultivating. After some time, she broke through again.
