"Who are these people? They are so cruel and ruthless?" Tang Jin said astonished.

"When we rushed in, they knew they could not escape, so they immediately took poison and committed suicide, a beat slower." Cao Bin explained.

"It's cruel enough, who can I find out?"

"Japanese." Lu Xiyan answered lightly.

"Can anyone tell the dead?"

"You can tell when you look at their toes. The Chinese people's toes are closed between the big thumb and the second finger. Only the Japanese wear wooden shoes all year round, and a gap has been formed in the middle. Although these two people have tried their best to change their living habits, they can still see it." Lu Xiyan said, "Also, poisons are not easy to deal with these days, especially potassium cyanide, which ordinary tissues cannot do."

"There are also Japanese people who are shorter, with their neck-legged legs, their body proportions are also different from those of Chinese people, and their facial features, etc."

"So you can tell at a glance who is Japanese and who is Chinese?" Tang Jin said in surprise.

"That's not necessarily. This can only be used as an auxiliary judgment. There are other evidences, such as the food they eat leftovers, types, tastes, etc., which are all basis for judgment." Lu Xiyan explained.

"Old Lu, I learned a lot when I am with you, Qi Huan, do you think so?"

"Yes, the Inspector is right. Consultant Lu is the treasure of our Political Department!"

"You mean old, are you?"

"No, absolutely no..."
