Chapter 502 Calculation

The sky was covered with thick gray clouds, and the light in Heifengao was dim.

On the porch of the wooden house, Chen Mu squinted his eyes and lay in a rocking chair, his left hand tucked into his wide sleeve, while his right hand on the armrest kept pinching.

At a certain moment, a glittering white spot came into view, and Chen Mu's hand movements slowed down.

"It's snowing."

He stood up and walked to the edge of the corridor, staring at the increasingly dense snowflakes. Unknowingly, he had been in Heifengao for two months.

When he came to his senses, the gray wall appeared in front of him.

Five Dragon Sutra: 3117/10000/Fourth Stage;

Nine Cups Calculation Sutra: 43/10000/Second Stage;

In the past month, the progress of the Five Dragon Sutra was acceptable, but the progress of the Calculation Sutra was extremely slow, and it was not until yesterday that it entered the second stage.

"Fortunately, the effort was not in vain." Chen Mu couldn't help but reach out to catch a snowflake.

Yesterday he calculated the weather and guessed that there would be heavy snow today, but he didn't expect it to come.

"People with rich life experience can roughly estimate the weather changes."

"The effectiveness of the arithmetic scripture needs to be further tested."

"Well, you can try to find the nearest gathering point of the Yin spirits."

...

Three days later.

The sky was still gray, and the entire Heifengao was covered with heavy snow. It was white as far as the eye could see.

The moon burdock tree, which was as tall as a person, was covered with snowflakes, and the fiery red leaves were huddled together, motionless as if asleep.

Chen Mu walked out of the wooden house, turned his body, and disappeared into the breeze.

According to the direction given by the arithmetic scripture, he did not stop all the way, followed the cold wind, and drifted straight to the southeast. He was more than 300 miles away from Heifengao before he reappeared at the foot of a small hill.

Chen Mu stood at the foot of a nearly vertical steep cliff, looking around with some disappointment.

Even though it was covered with heavy snow, he could easily see that there were no traces of Yin spirits living here.

"Tsk... After all, it's only the first level of perfection. It's true that we can't have too high expectations for the arithmetic."

"Go back and continue to work hard?"

Chen Mu couldn't help grinning as he thought about this.

The Nine Cups Arithmetic is difficult to figure out. It can only be practiced through repeated calculations, and the experience progress is slow. If he wants to practice to the third level, it may take a year or two.

And the feedback experience during the practice is too bad, so he really doesn't want to practice.

Just when he was about to turn around and leave, a strange sound came to his ears.

Chen Mu's heart moved, and he immediately activated the listening method. Then he raised his eyebrows and looked at the ground with interest.

Thousands of meters deep under his feet, there was a space as big as two classrooms. A strong man with a height of more than two meters was cooking in it at this moment? !

"Fellow practitioner!"

Chen Mu couldn't help but smile.

...

The next day, on the hillside on the east side of Heifengao, in a wooden house.

"Feng'an City?" Across from the square tea table, a simple-looking man with small eyes looked puzzled: "There is actually a city in this wilderness?"

This...

Chen Mu was speechless for a moment when he heard this.

The people in Heifeng'ao had at least heard rumors about the city, but the man in front of him had never heard of the city rumors.

The man was the Yin spirit he found yesterday. He had the ability to escape underground. In order to avoid the dangers on the ground, he dug a hole underground to survive.

The other party's hole was too deep. If Chen Mu hadn't had a good ear, he would have almost missed this person yesterday.

He had the ability to escape underground, which greatly improved his safety when he went out, and his range of movement far exceeded that of the Yin spirits in Heifeng'ao. But even so, the other party still didn't know the existence of the city, which was enough to show that the surrounding area was indeed desolate.

"Have you ever encountered other Yin spirit gathering places?" Chen Mu continued to ask.

"I did run into one a few years ago, but unfortunately, before I planned to move in, the village suddenly disappeared overnight." The strong man said, with a hint of fear on his face.

This is also the reason why he dug the hole so deep.

"Where is the village?" Chen Mu became interested.

"It's just north of the hill where I live, about two hundred miles away, in the middle of a valley." The strong man did not hide it.

Two hundred miles north, valley?

This location... wouldn't it be the mountain village where Old Yang stayed before?

Chen Mu hurriedly asked and checked carefully, and after a few words, he couldn't help sighing.

Although there are still some differences, he can basically confirm that the valley is most likely the ruins he found.

He was happy in vain.

"By the way, do you still remember where the Forgotten River you climbed out of?" After a while, Chen Mu calmed down and asked again.

"It's gone." The strong man looked puzzled: "I went back to look for it, hoping to find a few companions. As a result, such a big river disappeared completely, and nothing was found."

"I clearly remember that location." The strong man looked puzzled, and he really couldn't understand this strange phenomenon.

Chen Mu couldn't help but narrow his eyes.

He guessed that the Wangchuan River here might not be fixed. It sometimes disappears and sometimes appears, and there is no fixed river section.

Before killing the strange monster, the sudden appearance and disappearance of the Wangchuan River aroused Chen Mu's interest.

He specifically inquired about relevant information in Heifengao, and originally wanted to find the Wangchuan River and go up the river to find the traces of the city. But in the end, he found that the directions indicated by everyone were varied, and he found nothing after checking them one by one. Only in some places could he see some traces of dry riverbeds.

Just like what the strong man said, not long after the Yin Ling crawled out of the Wangchuan River, it would disappear out of thin air.

"But why doesn't the Wangchuan River near Jigu City and Feng'an City change?"

"I don't understand..." Chen Mu scratched his head.

"Forget it, it's useless to think so much."

"Now that I am in a remote and wild area, whether I continue to look for the Yin spirits to get information or go directly to find Feng'an City, I can't do without the Nine Cups of Arithmetic to infer the direction and guidance."

"Instead of thinking about it, it's better to spend more time practicing the Nine Cups of Arithmetic."

...

After a period of time, Chen Mu devoted more energy to the Arithmetic.

He didn't rush to find Feng'an City, but continued to look for the Yin spirits living in the surrounding area. While gaining experience, he also used this to verify the accuracy of the Arithmetic.

After half a month of busy work, he successfully found two Yin spirit settlements again.

The first gathering place is more than 400 miles southwest of Heifengao, with 70 to 80 people. He found it after calculating 19 times in a row.

The second gathering point is in an underground cave 600 miles north of Heifengao, where the environment is safer and nearly 300 people gather. He calculated 35 times before and after and finally found it.

"The farther the distance, the lower the accuracy?"

"It's a bit troublesome..."

He was not sure where Feng'an City was, but it was at least thousands of miles away from Heifengao.

"I can only try to calculate it multiple times to improve the accuracy."

With an idea, he stopped going out to look for ghosts.

Because the newly found ghosts were like the people in Heifengao. In their cognition, there had never been any state capital or big city. They were more of speculations and conjectures, which had no reference significance for finding Feng'an City.

As a result, he also had a clearer understanding of the remoteness of the place he was in. It was almost impossible to find Feng'an City through the news of ghosts.

"We still have to rely on the Nine Cups of Calculation."

...

On this day, snowflakes floated again in the gray sky, and the biting cold wind whistled.

In the wooden house, the clay stove stood under the window, and the yellow flames as bright as human heads ignited without firewood, and the whole room was baked warm.

Chen Mu sat cross-legged on the soft couch next to the stove, his gray-white clothes loosely wrapped around his body, and his long hair casually scattered.

At this moment, he was squinting his eyes, staring at a row of knotted straw on the low table in front of him. Dots of silver-white fluorescence flickered in his eyes, and as his fingers moved, a series of numbers emerged in his mind.

After a long while, Chen Mu opened his eyes.

"Southeast again?" He couldn't help but raise his eyebrows.

For more than half a month, he has been calculating with Feng'an City as the target.

Among more than 1,600 calculations, 223 of them pointed to the southeast.

And as the experience of calculations increases, the result of the southeast direction appears more and more frequently.

"Isn't this stable!"

Chen Mu couldn't help but smile.
