But Nanatsuki Koshimizu didn't react at all. When Tang Ze pulled her, she subconsciously pulled the rope towards herself.
And the next moment, an unexpected situation occurred.
The two ropes that were tied with a mouth-shaped knot and should have been very strong were actually torn apart.
Seeing the situation in front of them, both of them were stunned at the same time.
Because they had used the lip knot when camping and knew it was a very strong knot, they never expected it to be pulled apart.
Karasawa immediately took the two ropes and tied them again, then asked Koshimizu Nanatsuki to hold rope A, while he held the second rope tied to the knot, which was rope B.
After pulling rope B hard, the loop of rope A used for hanging was immediately pulled open.
"No wonder there's a second rope."
Nanatsuki Koshimizu suddenly realized what was going on: "So the reason rope B is tied to the knot of rope A is to be able to untie the open knot!"
"It's a safety device."
Tang Ze nodded and said, "You need Rope A to hang yourself, but even if you regret it, you can pull Rope B hard to untie Rope A around your neck."
"In other words, something went wrong in the middle, which led to Fujiyoshi Tomomi's real death?" Koshimizu Nanatsuki pondered.
"The exact truth is still unclear, but the way we tied the rope was copied from the murder weapon, which means there is no problem with the safety measures."
Tang Ze said, "But at least we don't have to worry about suicide and homicide appearing in the evidence.
Because it’s clear that the two are not opposites, but rather intertwined.”
"Then whoever tied this knot must know the details of this murder."
Nanatsuki Koshimizu said, "And right now, it seems that Kawase Haruna is the biggest suspect."
"People's subconscious actions can reveal a lot of things, and tying knots can also reflect a person's habits."
Tang Ze said: "The knot of rope B is to put the left rope on the front first, then turn the left rope up and tie a knot.
Then tie the first knot with the left side facing downwards and the second knot with the left side facing upwards.
Tell Takagi and the others what we have discovered and have them investigate Kawase Haruna. We will then go to the deceased's home and take a look at the deceased's knotting technique."
"clear."
Nanatsuki Koshimizu nodded and took out her phone.
The two drove all the way to Fujiyoshi Tomomi's home, found the newspapers that the other party had tied up, and then carefully untied them bit by bit.
