From the moment he had met Jiang Yunshan, Yu Tianzuo knew that he was an extremely intelligent man.

Although the current Cheng Guodong case was making him anxious, the biggest reason was that although this case was a premeditated 'murder case', the relationship between the culprit and the deceased was very special, and it was not easy to link the two, thus the reason why Jiang Yunshan was in a deadlock!

However, Yu Tianzuo believed that there would be a day when Jiang Yunshan would part with the fog and find some clues related information among some unknown clues, bringing the blame to Yu Tianzuo himself.

Yu Tianzuo wasn't afraid of death, nor was he afraid of imprisonment. But he felt that he couldn't just randomly become a murderer, he had to figure out why he wanted to kill Cheng Guodong. Whether the places he appeared in were real or fake, he had to investigate them one by one!

Therefore, Yu Tianzuo immediately made the decision that before Jiang Yunshan could find any clues related to him, he must clear himself from this case!

After thinking about it, Yu Tianzuo immediately went through his preparations. He waved towards Su Ya and said to her: "Ya, go and help brother find a Powered Paraglider's engine. Right, you must use the old one, as for this electric engine that I have modified, you will help me take care of it.

Su Ya nodded her head, but there were too many questions in her heart, so she asked curiously:

"Bro, you used the electric motor well, why would you change it for oil?"

"Ya, there are some things you need not ask, you must remember to clean up this engine for me, you must not let anyone know about this!"

Thinking of this, Yu Tianzuo added another sentence: "Even if it's Wang Jiahuan, you can't let her know!"

It had already been a few years since Su Ya last saw such a serious expression on her face. She immediately understood the importance of this matter, so without asking any further, she took out a screwdriver type tool and removed the electric motor.

Immediately, Yu Tianzuo returned to his bedroom.

As he had never worked in his office at all, there was also a huge desk in his bedroom.

Yu Tianzuo took out a detailed map of the Lincheng City from the table and marked out the scene of Cheng Guodong's death on it with a red pen.

I remember Wang Xiaochuan telling me before, that Jiang Yunshan and the others used the radius of the crime scene to search for twenty kilometers but did not find those two hands, that can only mean two things. Firstly, after killing Cheng Guodong, I did not bring the hands that far, and secondly, I brought them even further, with a distance that none of them wanted to estimate, but personally, I think that the possibility of the second point is very high! "

Yu Tianzuo lit up a cigarette for himself. Because his chest was always sick, he normally did not smoke much, but at this moment, the cigarette seemed to have been blown by an evil wind, or perhaps, it was as if someone else in Yu Tianzuo's body was helping him smoke the cigarette, and the smoke quickly burnt away.

This time, he did not use his mouth to smoke the cigarette. Instead, he held the cigarette in his hand, closed his eyes and tried his best to recall the environment he was in in in in his dreams.

Damp, fire, a brazier, burning hands, and … A group of rustling trees!

"Is it a mountain?"

Yu Tianzuo suddenly opened his eyes and started to look for possible "Burning Hand" locations on the map.

At this time, the Great Hidden Mountain, which was fifty-one kilometers away from the place of the crime, suddenly appeared in front of Yu Tianzuo's eyes!

"If that place is really a forest within the Great Hidden Mountain, then it would really take a lot of effort for Jiang Yunshan to find it. Furthermore, to the worst of it, whether or not he could find that place in his entire life is unknown."

Yu Tianzuo shook his head, after pondering for a long time, his head felt heavy, but he was actually fighting against time, he could not stop, and could only continue thinking.

"The next question is, how did I get to that place?"

The door to the bedroom was not closed. Yu Tianzuo turned around and saw that Su Ya had already removed the electric motor and put it in a box.

Su Ya was a very smart and sensible girl.

Since Yu Tianzuo had told her to do it so that she wouldn't leave any traces behind, she went and found a dozen or so paper boxes and threw them into them one by one, messing up the placement of the parts. Even if someone found out about this, they wouldn't be able to find out that it was an electric engine from the Powered Paraglider.

Seeing his own little sister being so careful, a pleased smile appeared on Yu Tianzuo's face, and she started to think:

"If one were to say that I used two days of time to kill Cheng Guodong, then it should have been on the eighth night, when I rode the Powered Paraglider and hid at the roof of the Yiyuan Housing Estate, and before nine o'clock on the evening of the ninth, I called open Cheng Guodong's house, and only then did I kill him."

"Jiang Yunshan investigated all the surveillance cameras along the way and none of them noticed me going in and out of the Yiyuan Housing Estate. That only proves this, that after I killed Cheng Guodong, I must have also left on a Powered Paraglider!"

"But I need an idea for this, and that is that the flying distance of an electric Powered Paraglider is obviously smaller than the flying distance of the oil, and can only fly 10 kilometers. However, this 10 kilometer distance includes the distance that I need to travel when riding a Powered Paraglider to get here, so, after killing Cheng Guodong, the distance that I need to travel when riding a Powered Paraglider will definitely be greatly reduced. I definitely need another transportation vehicle in order to reach the Great Hidden Mountain and burn Cheng Guodong's hands!"

"Looking at the wind and wind on that day, the place where I can take off and land is within a 10-kilometre radius … It can only be these two places! "

Looking at the wind report from the day before and the analysis from the entire map in Lincheng City, two names that he felt extremely familiar with were reflected in Yu Tianzuo's eyes.

Lincheng City Nine Song Tower!

Lincheng City Saint Doctor's kindergarten!

Yu Tianzuo could not help but be shocked in his heart: "How could it be these two places? Am I wrong? "

After thinking about it, Yu Tianzuo confirmed the location on the map once again. But looking at the wind that day, the best place to take off and the place to land could only be these two places.

Yu Tianzuo was stunned!

The Nine Song Tower was one of the most eye-catching iconic buildings in Lincheng City, with a total of 55 floors. Its strong security capabilities allowed it to be known as the world's leading technology, and ordinary people would never be able to enter it, let alone fly to the top floor of the Nine Song Tower to take off their Powered Paraglider.

As the richest man in Lincheng City, Yu Tianzuo had long heard of Zhao Jiuge, but the two of them didn't have any connections. It was impossible for Yu Tianzuo to take a step into the tower as a "friend"!

But this was strange, since Yu Tianzuo was unable to enter Nine Song Tower, how did he enter? This was a somewhat illogical question. To the current Yu Tianzuo, he really had no way of unlocking it, he did not even have a tiny bit of memories!

"Is there something wrong?"

Yu Tianzuo tapped his forehead with all his might, but the map of Lincheng City was right in front of him, and he firmly believed that his judgement was not wrong.

"Since I can't figure it out, I might as well not think about it. Let's look at the land first."

"It's just that I didn't think about it before, and didn't know if Huan had participated in this case. Sigh, if I had really unintentionally dragged her into this, then I would really let her down!"

Yu Tianzuo rubbed his forehead, he wanted to pick up the phone and call Wang Jiahuan to ask, but he was afraid that some other unforeseen event would occur, so he chose to stay silent.

At this time, Su Ya's voice sounded out: "Brother, I've packed everything, should I throw them out, or leave them at home?"

Yu Tianzuo thought for a moment, then said: "How about this, you go to the delivery company, and use anonymous means to send all of these items to the delivery transfer station in Linhai City. I will be going to the Linhai City with Liu Qian for the next few days, I will handle this myself after we get there."

"Sure, then we'll do as you say."

Su Ya nodded her head. Although her eyes were filled with doubts, the girl still suppressed them inside her heart and did not choose to increase the pressure on her brother.

In Su Ya's knowledge, Big Brother Yu Tianzuo's words were forever correct!

Thinking about it, Su Ya decided to simply leave and send her an express delivery, but Yu Tianzuo suddenly called out to her, and asked: "Oh right, Ya, remember, on the 9th night, from 9: 30 to 10, is Wang Jiahuan at home?"

"Oh, let me think." Su Ya bit her lips lightly for a while, and in the end, still apologetically shook her head and said: "Brother, I'm sorry, I seemed to have forgotten. I remember that day when I was especially tired, and seemed to have slept really early! What's the matter with you? Why do you care so much about those two days? Please, brother, can you tell me? "

With that, Su Ya took the opportunity to grab Yu Tianzuo's hand, and started acting coquettishly in front of him, revealing a great deal of worry within his cuteness.

Yu Tianzuo did not want Su Ya to worry, so he made up a simple excuse and said: "It's nothing big.

Touching Su Ya's smooth hair, Yu Tianzuo turned around and directly returned to his bedroom.

After Su Ya left, Yu Tianzuo still had not made up his mind. He wanted to give Wang Jiahuan a call and ask him. The biggest reason was, in Wang Jiahuan's eyes, his image was always mature, calm and steady!

Yu Tianzuo was not afraid of ruining his image in Wang Jiahuan's heart, but knew that Wang Jiahuan was a sentimental girl, and through the interactions he had with her during this period of time, Yu Tianzuo had also discovered the feelings Wang Jiahuan had for him. Although Yu Tianzuo did not plan to accept her, she also did not want Wang Jiahuan to worry about her either!

"What should I do?" Yu Tianzuo scratched his head anxiously and thought: "Forget it, I'll not look for Huan first. Since I figured out that Cheng Guodong's hand was left behind in the Great Hidden Mountain by me, then I will follow this lead and investigate!"

He left just like that!

Right at that moment, the phone in his hand rang. Yu Tianzuo looked down and could not help but laugh bitterly!

She didn't want to give Wang Jiahuan a call, but took the initiative and called her over …
