The Sky Clinic was quiet. A puff of black smoke and a stream of white smoke intertwined in the good-evil tripod, curled up, floated in the air, gathering together instead of dispersing.

Coming back from the Sunshine Orphanage, Ning Tao was immersed in spiritual power practicing.

There were both evil energy and good energy in the good-evil tripod, forming the harmony between Yin and Yang, which were equivalent to provide him with a perfect practice condition. After he cured Zhou Yufeng, only three of the Primary Elixirs remained, so the refining of this kind of elixir was urgent. Besides, it was a matter of life. How dare he relax his will to practice?

He practiced the ABC of elementary cultivation method over and over again…

As the Niwan acupoint swallowed and spat, a trace of black and white air entered the point between his eyebrows. With each movement, his body was tormented by heat and cold. He felt as if the left half of his body was in boiling water, while the right side was in ice water. With his spine as the dividing line, one side of his body was hot and uncomfortable, and the other was bitterly cold.

It was only the flesh that felt it; the most painful feeling was from his soul. His soul was like the Face-Changing in Sichuan opera. For a while, he was a gentle, kind man with the great love in his heart, but the next second he had become a hideous villain who wanted to destroy everything. Had he not been a natural go-between of good and evil, he would have split his personality and gone mad.

All of a sudden, the little spiritual power in his Niwan acupoint changed. It was stronger and its color became half black and half white.

Ning Tao’s innate aura had also quietly changed. A black aura and a white aura slowly enhanced, and finally slowly turned up. Its shape was like the Yin and Yang symbol of Taoist, and Ning Tao was the core of this symbol!

If Chen Pingdao were here to see what was happening to Ning Tao, he would be stunned, because he had never encountered such a strange situation in more than 2,000 years of running this good-evil clinic.

Ning Tao, a beginner practitioner, thought it was normal, so he threw himself into the world of cultivation…

Then the whole night passed.

When his practice ended, Ning Tao was lying on the floor, and ached all over, as if he had been hit with a hammer. This was a side effect of the spiritual power flowing through his body and hardening his body. It would further increase his strength, speed, and reflexes. It was a tiny improvement, but in the ordinary world, it was quite remarkable.

In fact, his biggest gain this time was the improvement of his ability to sense and control spiritual power. He needed his divine sense to go into the Niwan acupoint to see the spiritual power before, and now he could feel the presence of spiritual power in his body without doing that. He also became more skilled in the manipulation of spiritual power. He could harness it with a single move of his mind.

After a short rest, Ning Tao got up from the floor. Then, he raised his right hand up, moving his mind, and then a trace of spiritual power emerged from his palm, one black and one white, like a black and white fry looked through a frosted glass tank.

Ning Tao tried to control the “black and white fry” and produce alchemy fire.

Regard the body as the tripod, guide with the soul to produce the alchemy fire.

That was the description in the ABC of elementary cultivation method. The content was simple, but the actual operation was rather difficult.

The first attempt failed.

The second time failed.

He kept trying, and failing…

After a dozen failures, Ning Tao stopped trying. His spiritual power was too weak. If his body were an engine and his spiritual power a fuel, his fuel would not wet the pistons of the engine. How could he fire the engine to work?

But his efforts were not entirely in vain. More than a dozen attempts gave him a preliminary understanding and familiarity with the technique of transforming spiritual power into alchemy fire. As long as his spiritual power met the conversion requirements, he would take fewer detours and be more likely to succeed.

Growl, growl…

His stomach suddenly made a strange noise. Hunger and appetite sprang up. A wry smile broke on Ning Tao’s lips. “What I’m thinking about is all about practice. I have never thought about how I’m going to make money. I have to eat,” Ning Tao murmured to himself.

Leaving the clinic, Ning Tao found an ATM and withdrew all the 300 yuan left in his bank account. Then he went to a small restaurant and ordered a bowl of noodles. While eating the noodles, he kept thinking about how to make money. The Sky Clinic didn’t make money and he didn’t have time to work. As a result, he was stumped by money.

At this point, a motorbike with a sign to clear the drain stopped in front of the restaurant, and the man on the motorbike walked into the small restaurant. He looked dirty, and gave off a smell of sewer. Obviously, he had a hard life.

As Ning Tao’s eyes fall on the advertising sign on the man’s motorbike, an idea came to him.

The man ordered a bowl of noodles and two steamed buns. Clearly, he was quite hungry.

The owner, disgusted by the smell of him, put on a cold look and even did not even welcome him.

Ning Tao paid the bill before he went to the man, smiling and asking, “Excuse me, where did you make the sign on your motorbike?”

The man took a glance at Ning Tao and asked, “Why do you ask?”

“I’m a craftsman too, and I want to make a sign,” Ning Tao replied.

“You can do it in any shop that makes billboards.” The man then asked, “Young man, what do you do?”

“I’m a medical student,” Ning Tao answered.

“A medical student?” The man laughed. “Are you kidding me? Aren’t all the doctors working in hospitals now? Is there a doctor walking around from house to house with an advertising sign?”

Ning Tao leaned in his ear and said, “I’m not like the other doctors. Do you drink almost every night?”

The man froze for a moment and asked, “How do you know?”

Ning Tao replied in a hushed voice, “Most of the drinks are mixed with alcohol nowadays. Your esophageal mucosa is inflamed and ulcerated. Stop drinking and drink water with Violabetonicifolia Smith. Keep drinking it for a month, your esophagus can be recuperated.”

“Are you seeing me?” The man asked, looking quite surprised.

“The Violabetonicifolia Smith is an herb, common in fields and easy to find.” Ning Tao said. “Trust me, you’ll be safe. If you keep drinking, you will be in danger.”

“I’m not going to pay you,” said the man warily.

Ning Tao smiled and said, “I don’t want your money. You told me where to make the advertising sign, and that’s what I gave you in return.” Then he turned and went to the door of the small restaurant.

The man looked at Ning Tao’s back and said to himself, “It’s strange, how does he know I drink almost every night? Whatever, just get some Violabetonicifolia Smith and drink water with it.”

The streets were busy.

Ring, ring, ring…

Ning Tao pulled out his phone, looked at the caller id, and then answered the phone, “What? Go ahead.”

Jiang Yilong’s voice came from the phone. “Miracle Doctor Ning,” he said, “Zou Yulin asked me for your telephone number. He said he had something very important to talk to you about. May I tell him your number?”

“Send me his phone number and tell him to wait for my call,” Ning Tao answered coldly.

“Okay, okay,” Jiang Yilong replied carefully. “I’ll text you.”

Ning Tao’s voice turned colder. “Have you done everything I asked you to?”

Jiang Yilong became nervous instantly. “I’m doing it. Give me a few more days, and I will finish it.”

“You’d better not let me remind you a second time.” Then Ning Tao hung up.

Seconds later he received a text from Jiang Yilong with Zou Yulin’s cell phone number.

Ning Tao just shot a glance at it and put his phone away.

“Zou Yulin, you want to see me? Don’t think you can you see me as you want! You wait!”

A little way down the street was a little shop that made advertising signs. Ning Tao walked towards it.

The roving doctor was an ancient profession, which had disappeared in modern society. However, Ning Tao was now going to take this job and make it big!
