Sometimes, in some places, the long years seem to be a little hurry after seemingly endless suffering and long wait.

If we say that time is like water, not only flowing in a hurry like water, it will pass in a flash, but it also has a characteristic that is particularly like water. When there is water, it is not known to cherish it. Only when it is lost can it be valuable. When it is discovered, it is known that everything has disappeared. It is too late, it is over...

Time never forgives others, can people leave the water?

Yi Tianhang and his group experienced a long journey on the alien planet. After returning to Earth, they calculated the time and half of the semester had passed!

Seeing that tomorrow is Double Ninth Festival, Yi Tianhang also realized that he had another earth-shaking event that he had not completed, not to make a name for himself, but to punish evil and promote good.

Yi Tianhang led Zhang Bo toward Xuanwu Gate. He had already understood the purpose of Zhang Bo going down the mountain, so this time he met Wu Song, Dutou of Xuanwu Gate, who were walking together...

...

...

Bang bang bang bang...

"Please come in!"

After hearing a familiar, elegant and steady voice, Yi Tianhang slowly pushed open the office door and walked in on tiptoe. Zhang Bo followed closely behind him.

Think about it, he hasn't seen Wu Song for many days...

"Oh, it's Xiaohang! Who is this?"

Wu Song carefully looked at the young man next to Yi Tianhang, who was about the same age as Yi Tianhang. When he saw this person, he felt that he was majestic and extraordinary, and he must have a great background.

"Uncle Wu, this is the true disciple of Zhang Jingyu, the current leader of the Tianshi Mansion of Longhu Mountain. Zhang Bo." Yi Tianhang pointed at Zhang Bo and recommended to Wu Song.

"My younger generation Zhang Bo pays homage to Wudu Head."

Zhang Bo is very polite. He has no airs of the future heir of the Tianshi Mansion in Longhu Mountain. Naturally, he dare not act rashly in front of his seniors.

"Um!"

Wu Song nodded with a smile, and then continued, "The younger generation pushes the older generation forward, and the younger generation is better than the younger generation!"

"Wu Du praised it!"

Zhang Bo gave a compliment.

"I wonder what is the price for the future heir of the Tianshi Mansion in Longhu Mountain to come to my Xuanwu Sect?" After finishing the politeness, Wu Song naturally got back to the point.

"I heard from my master that it seemed that Wu Dutou had been to our Longhu Mountain more than two months ago?"

"Yes, does this have anything to do with your purpose of coming to Xuanwu Gate this time?"

Zhang Bo just smiled slightly.

"I'm not hiding the head of Wudu. Recently, the serial murder case of tiger demons that has caused a lot of controversy in the world is related to my old case in Longhushan. Master sent me here to investigate this matter."

"Since that's the case," Yi Tianhang said, "Brother Zhang, can you tell me what kind of seven-star plate dragon fighting evil pattern in Longhu Mountain?"

"Sorry, it's up to me, Longhushan's secret, not something I can decide alone."

"Well, that's how it is!"

Yi Tianhang's tone seemed full of disappointment, but he wanted to know what the real Seven-Star Plate Dragon Fighting Evil Character looks like!

After all, not all kinds of knowledge can be found online. Some things can be found only popular science, some can only find one name, while others cannot even find a name...

At this time, Yi Tianhang had already turned on his laptop.

He continued, "This is my homemade simulation tracking system. Brother Zhang, please see, the seven places marked on it are the seven places that are most likely to appear when the murderer sets up the last Faltan."

"Wow! It seems that I have been in the mountains for too long. Nowadays, computers can replace human brains! Tsk tsk..." Zhang Bo sighed at the map on the screen of the laptop.

"Brother Zhang, computers can never replace the human brain! Programs are always designed by humans!" Yi Tianhang said with confidence.

"Haha, of course I know that the program was designed by you. I just don't know, what else did you find? I'm very curious!"

As he said that, Zhang Bo stared at Yi Tianhang in surprise, his eyes full of expectations.

After a stalemate for a while, Yi Tianhang just said two words lightly: "Double Ninth Festival!"

"Double Ninth Festival?"

Zhang Bo asked back.

"According to my calculations, if the murderer sets the time for Fatan, he will choose the Double Ninth Festival."

When it comes to the word "calculation", Yi Tianhang seems to have already understood the mysterious yellow world and the vast universe...

"How can I see it?"

As he said that, Zhang Bo continued to look into Yi Tianhang's eyes, and a strange smile appeared on his face.

"Yin and Yang of Tao!"

"Yin and Yang of Tao? Do you understand Taoism?"

Yi Tianhang just smiled and shook his head.

"The alternation of yin and yang is a natural and eternal law. Since the murderer killed someone and was the soul of the extreme yin, he would definitely choose the extreme yang place. Think about it, only on the day of Double Ninth Festival, the yang energy is the most prosperous, and he should choose the noon!" Yi Tianhang said.

"I can't tell, you kid still understand Feng Shui!" Zhang Bo jokingly said.

"It's not me, it's it!"

As he said that, Yi Tianhang took out his cell phone and showed off in front of Zhang Bo.

Wu Song, who was standing aside, didn't say anything, but just listened patiently to the conversation between the two boys, just to see what they two young boys could figure out. After all, the Yangtze River pushes the old waves, and even the old world will one day withdraw from the social stage.

"Didn't it mean that computers can never replace the human brain?" Zhang Bo asked in confusion.

"It's one thing to be smart or not, and the amount of information stored is another thing." Yi Tianhang explained, "Just like the concept of limits, computers can never understand it! What computers can do is always only store, calculate, and execute, and they cannot understand things like humans. Even simple infinite and non-circulating decimals cannot understand..."

Zhang Bo just shook his head slightly.

"Let's talk about serious matters! Tomorrow will be Double Ninth Festival!" Zhang Bo said.

"Oh well!"

Yi Tianhang pointed to the computer screen and continued: "Brother Zhang, look at these seven locations. Which location will the murderer choose to set up the Fatan?"

Zhang Bo observed for a long time...

Silent...

"It seems that the computer budget is still too much. Since the murderer can choose seven star positions when killing people, why does it have to be in one place to set up the Fatan?" Zhang Bo said.

Yi Tianhang nodded thoughtfully.

"Since that's the case... wait a moment! Modify the code..."

He rethinked the procedure, and then the patterns on the map began to be rearranged again. After a while, seven places were marked with red lines, and the pattern was completely the Big Dipper.

"Master!"

Zhang Bo praised him with a thumbs up.

"where?"

Yi Tianhang smiled slightly and continued, "Since that's the case, Brother Zhang, where do you think the murderer will appear?"

Zhang Bo also smiled slightly.

"It's great that you can detect the Big Dipper Seven Stars array from the copied topographic map. However, you ignored a little bit of the star in the starry sky that is closely connected to the Big Dipper Seven Stars..."

"Brother Zhang means, Polaris?"

Yi Tianhang's tone was filled with surprise. Sometimes, the answer to the question was far away in the sky and near in front of us, which was because we were too complicated to think.

"That's right, so the place where the murderer may eventually appear is here, the rooftop!"

While speaking, Zhang Bo pointed at the location of the "North Star" - the rooftop.
