Professor Zhou lifted the deep glass lens and held the sealing bag high facing the window, so that the sunlight shone through the leaves.

"Ginkgo biloba is a good boy~ It can detoxify and release poison, and it can be used as medicine all over the body, and it will last for a long time." The professor said.

Li Yiji stood beside Coco and lowered his voice, "I said she treats plants as a girl." ”

Coco was noncommittal and glanced at the large cabinet full of botanical books behind the professor.

"Xiao Li, don't think I'm behind my ears~" The wise eyes under the thick glass lenses glanced at Li Yiji.

"Xiao Lizi doesn't dare, Queen Mother, can you see anything?" Li Yiji said with a smile.

"What do you expect me to see? One Leaf One World? ”

Li Yiji pointed to the silent Coco, "This girl originally hoped to determine the age of this tree." ”

"Impossible." The professor spoke, and the three of them were speechless for a while, and the professor took off his glasses, "What do you want to know about the age of this tree?" ”

"I suspect that it comes from an old ginkgo, the old ginkgo that is said to be hundreds of years old in the old campus of the normal university in the west of the city, but I have no evidence... So,"

"Normal University? Ah, you're talking about that child," Professor Zhou put on his glasses again and brought the ginkgo biloba in his pocket to the light, "I remember that child, when I was young, I did research and learned all the special children in the whole city in detail. She got up and found a thick notebook in the huge bookcase.

"Hmm, no, this is the ...... from the east," she searched slowly, and finally locked onto a black-covered notebook, and opened it tenderly with her hands and feet, and there were pages and pieces of dried leaves in it, and in this record book, which was as thick as an encyclopedia, she carefully took out one with tweezers, "Leaves, they are the children of trees, so they do not reflect the age of trees." They fall in droves every year, year after year......"

The two leaves were side by side in the light, and Professor Zhou, who was holding a professional magnifying glass, was like a mother, babbling, "...... But between the leaves, like brothers and brothers, will show ...... The same growth vein, what kind of light has been experienced, how much rain every year, even if you are not born in the same year, as long as the climate has not changed dramatically, you will have the same soul. ”

Under the light and magnifying glass, two ginkgo biloba leaves have almost perfect identical veins.

"Ah~ That's right, these two pieces are from that child."

"Is it the centuries-old ginkgo from Chengxi Normal University?" Coco forced the excitement in her tone.

"Yes, that child's tree is about eight hundred and fifty years old, ah, no, I measured it forty years ago, and now it should be eight hundred and ninety years old......" Professor Zhou looked up at the window, completely different from Coco, and fell into a sigh of time rush.

"Professor, how sure are you?"

"Xiao Lizi, when you ask me this question, you look down on me, and my scientific research data may not be directly adopted in court, but from the perspective of providing you with clues, there is not 100%, there are also 99." For the first time since Coco and the two of them entered the door, Professor Botanical smiled.

――――――――――――――

"You've got all the guns, right?" Da Xuan shouted at the people who were about to leave in the criminal police office: "Attention everyone, we may be empty, but it is also likely to face the suspect directly. Remember, the first thing is to save people, and then to control the suspects! ”

Just as he was about to lead the team out, Coco gasped and blocked the door. "I know where that guy had surgery!"

"We've found suspicious locations."

"Is it in the west of the city?" Coco asked.

Da Xuan avoided her words, "You just wait here for news." ”

"No, if it's not in the west of the city, you're looking for the wrong place, at most it's a smoke bomb."

Everyone turned their heads and looked at Zhou Daxuan. He frowned and fell silent, "Xun Keran, come here." ”

Closing the door to the small office, Da Xuan lowered his voice, "What did you find?" ”

"Where he probably used it for surgery!" Coco saw distrust in the other party's eyes, "I have evidence, I just asked a plant expert to identify this leaf, it should come from a very old ginkgo tree, ...... when I was a child"

"Coco." Da Xuan interrupted her, "Memories from childhood cannot be used as evidence. ”

"But this ginkgo biloba appears in many places, and it ......"

"That's not real evidence, do you think it's effective in law?"

"Is it time to go to court? Now the man is in his hands, as long as he finds the scene......"

"What if it's too late? What if you find a site that is just remnants? ”

"Where did you find the suspicious spot? How can you be sure that's not a trick? "Coco is pressing closer.

Da Xuan sighed, "I'm not trying to compete with you about who is more correct now, that's right, time is pressing, so we have to be more cautious, now that the team is arranged, I can't ......"

There was a soft knock on the door, "Team Zhou......"

Da Xuan was stunned for a second, and then opened the door, "Wang Aiguo!" Turning to Coco, "When we rush this suspicious warehouse, if it's a trick, I'll come back with you immediately." ”

Wang Aiguo was at the door, "Captain, you called me?" ”

"You stay here, don't let her leave my office."

"Huh? Huh? Wang Aiguo was surprised by Zhou Daxuan's decision.

"Zhou Daxuan! You just don't think it's credible for me to make inferences based on what I know about Hou Guangyan in my memory, right? Coco asked, holding out her breath.

Da Xuan didn't look back, "As the captain of the criminal police, that's right, that's how I judged." Then he strode away.

The door of the small office was closed, and Coco found that Wang Aiguo quickly took the simplest and most effective way, locked the door, and then begged Coco for mercy through the door, "Sister Xun is not what I want to lock you, the captain has no way to explain it, my salary, oh, my net worth, my life is pinched in the captain's hands, so it is not very accurate to say this, in short, he knows a lot of ...... about me"

Bang dang! Wang Aiguo can also clearly know through the door that Coco smashed something on the door just now, okay I'll shut up, but I don't dare to go away Woo, Wang Aiguo moved a chair and squatted at the door. Ahhh......h

Coco sat on the sofa, turned on the phone and found that it was automatically turned off when the battery was out, she turned around twice in annoyance, and unceremoniously opened Zhou Daxuan's drawer, intending to find a charger. When she opened the second drawer, she froze......
