Did he think that he could rest easy just by losing a cell phone?
On the contrary, losing the phone actually revealed his location to us!"
"Hmm? Do you have any method?" Hattori Heiji couldn't help but ask curiously when he heard that.
"Do you know Local's Law of Exchange? Whenever two objects come into contact, something is left behind and something is taken away."
Tang Ze smiled and said, "Yakushiji gave us the phone, which is like giving us a locator that tells us where he is.
We can collect the substances that the mobile phone comes into contact with and see if we can gain anything.
It may not be accurate, but at least it gives us an idea of where he has been.”
"Then I wish you good luck in getting useful information."
After hearing Karasawa's explanation, Hattori Heiji also understood the other party's tracking method. Suddenly realizing it, he said, "I will continue to investigate. I plan to visit Kato Takanori's father later to see if I can find anything."
"Okay, if you find anything, please contact me immediately. If I don't answer the phone, just text me."
Tang Ze thought for a moment and then warned, "Be careful. After all, it happened 18 years ago. No one knows what happened back then, nor does anyone know if any of those four children were local accomplices."
"I understand. When I take action, I will ask the local criminals to join me." After hearing Tang Ze's instructions, Hattori Heiji realized that the other party was worried about his safety, so he nodded and agreed.
It is normal for Tang Ze to have such concerns. After all, in many old cases, the protagonist goes to investigate alone, and ends up being targeted by people who want to keep the secret.
Then, he would launch a sneak attack to silence the person with a deliberate move.
Of course, whether you can survive depends on luck. If you have luck, you will die slowly, such as disguising it as an accident so that teammates can arrive at the critical moment.
If there is no luck, then it might be a complete failure.
Of course, with Hattori Heiji's luck, he would at most encounter some dangers. After all, he is half a son of the "World Mother".
However, the current case is not the "scientific case" in memory, and Tang Ze does not dare to bet whether Hattori Heiji's luck will be useful in these side cases.
So instead of gambling on luck, it is better to eliminate the danger from the beginning. After all, it is not a bad thing to be cautious.
Hattori Heiji had also experienced many ups and downs, so he naturally listened to what Tang Ze said. He found the criminal director of the Nishishigura Criminal Bureau and asked him to send someone to investigate with him.
Because the skeleton was actually discovered here, the local police also took it very seriously. In addition, it was originally discovered by Hattori Heiji and his men, so his request was easily agreed to.
Hattori Heiji continued to investigate the death of Kato Takanori, while Karasawa was patiently waiting for the test results of the mobile phone.
Fortunately, the tests related to this case are now top priority, so Tang Ze didn't have to wait too long. Saito Hiroshi came over with the verification result report.
"Although the amount is small, we also extracted substances from the gaps between the phone buttons and found copper oxide and acrylic resin."
Handing the report to Tang Ze, Saito Hiroshi said directly: "Copper oxide is generally used in antifouling agents."
"Isn't it used to prevent shellfish and other marine organisms from attaching?" Nanatsuki Koshimizu came over at some point and spoke after hearing what Saito Hiroshi said.
"Why don't you continue to rest?" Tang Ze asked when he saw the other party coming.
"You've rested enough, and if you don't wake up you'll have to solve the case yourself."
Nanatsuki Koshimizu rolled her eyes at this, then looked at Saito Hiromichi and said, "Let's get back to business. Where is copper oxide usually used?"
"Yes, looking at the ingredient report above, this should be a kind of paint, and it is mainly used on the surface of ships."
Saito Hiroshi's words instantly made Tang Ze and the others lose their composure. They had both read the information of Yakushiji and Kawada Kyota, which naturally also included each other's life experiences.
Although Yakushiji had no experience working with docks and ships, they remembered that Kawada Kyota, who died at the beginning, had experience working in this area!
It’s no wonder that the large army searched the area for so many days but still couldn’t find Yakushiji’s whereabouts. It turned out that he was hiding in the place where his companions once worked.
This place has nothing to do with him, and when the large army searched, they obviously only focused on places related to him, and did not think about the deceased Kawada Kyota.
After all, in the eyes of others, these are completely two cases, so the truth is hidden.
Even Karasawa and Nanatsuki Koshimizu had not noticed the suspicious points in this part of the two men's resumes before.
After all, before they became drug dealers in Yakushiji, they did many odd jobs. This job was not conspicuous among the other jobs, so they did not pay too much attention to it.
But now, combined with the information found on Yakushiji's mobile phone, we can lock on to the possibility that the other party is hiding in the place where Kawada Kyota once worked!
"I'll go get the information about Yakushiji right now!" Nanatsuki Koshimizu said and immediately ran away, and Tang Ze did not stop her.
After all, there were too many materials to look at at the time, and the other party's work history was too long of short-term jobs. Tang Ze only looked at what the other party had done, and he really couldn't remember where the other party worked specifically.
