Qi

After a week, Chu Fan went to sell wood at Old Man Guo's store as usual. However, when he tried to sell the wood, Old Man Guo said, 'Sorry, boy, but I can't buy more wood. My store is filled with enough wood to last for half a year. If you want to sell more, go to another store.' Chu Fan was surprised by Old Man Guo's response and went to have lunch at the nearby restaurant. After finishing his meal, he went home.

He sat on the ground in a meditative position, thinking about what to do next. He had collected a sum of 120 copper coins, enough to last him for about a month and a half.

He thought about the gray ball he had tried to see again last week but failed.

He closed his eyes and tried to concentrate, and after two hours, it appeared to him again. Chu Fan was surprised and tried to attract it to his body by inhaling, but he couldn't.

After half an hour, he stopped focusing because his body began to ache severely. He lay on his bed to find a way to attract the gray ball. He tried to remember how he did it the first time and realized that it was not his body that attracted the ball but his mind.

After resting, he sat down again and entered a state of concentration. After an hour, he saw the ball again, much faster than the previous time.

Chu Fan thought in his mind to attract the ball to him, and after several attempts, the ball began to approach him until it entered his body. He felt a strange sensation of refreshment and opened his eyes. Unlike the previous time, his body did not produce the black liquid. Chu Fan was delighted and tried to focus again. After half an hour, he was surprised to see a larger number of balls around him. He decided to absorb them and focused on one of the balls until it entered his body. He continued this process until the sixth ball. Chu Fan decided to follow the path where these balls were going, and after tracking them, he was surprised to find an area in his brain where nine separate gray balls were gathering. After a few minutes, he decided to continue collecting the balls. He collected the tenth ball until he heard a cracking sound in his body. He felt pain in his body but also a sense of security, so he decided to continue concentrating. After a few minutes, the pain subsided, and he ope

When he left the house, he ran quickly and realized that he was much faster than before, almost losing control of his balance. He tried to stabilize himself to avoid falling and controlled his speed. It took him ten minutes this time to reach the river, and when he arrived, he threw himself into the water and washed his body thoroughly. After leaving the river, he lay on the ground, looked at the sky, and counted the stars. This time, he counted 3002 stars in a minute. Chu Fan was surprised that his eyesight and counting speed had improved. He closed his eyes and fell asleep.

Chu Fan woke up in the morning, went to the market, had breakfast, paid the bill, and walked home until he arrived.

Inside his house, unlike the previous time, Chu Fan controlled his weight to avoid breaking the floor. He sat on the ground in a meditative position, entered a state of concentration, and began to collect the balls until the sky darkened. He heard a cracking sound from his body again and looked inside his mind to find twenty gray balls.

He continued this pattern for two days, collecting the balls until he heard a cracking sound again. He went to the river to wash his body from the black liquid.

On the third day, after hearing a cracking sound from his body, he went to wash his body from the black liquid. He decided to name it "Impurities" because he noticed that his body was cleaning itself from these impurities by removing them from the body. After finishing washing his body from the impurities, he found that his speed, body hardness, and strength had increased after each break in his body. Therefore, he decided to name it "Qi."
