Yu Lao glanced at him and said lightly: "Yiyi Xiaoyou doesn't want to join the Dragon Pavilion for the time being. ”

When the words fell, he didn't wait for Chang Xingxia to ask another question, so he said: "You put down your things, go to handle the entry for Dongfang Xiaoyou, and send the things that belong to him by the way." ”

Chang Xingxia heard that Yu Lao was angry, and he didn't dare to come out, so he hurriedly said, "I'll go now." ”

As he spoke, he hurriedly put the things on the coffee table beside Yu Lao, smiled politely at Lin Yiyi and Dongfang Xu, turned around and went out again.

Lin Yiyi smiled: "Old Yu, Chang Lao seems to be afraid of you?" ”

Yu Lao smiled and said, "Why is he afraid of me?" I obviously want to stay away from my old man. ”

Lin Yiyi didn't bother with this question, and looked curiously at the document bag on the coffee table.

Yu Lao pushed forward: "Dongfang Xiaoyou, Yiyi Xiaoyou, you can take a look, what clues can you find?" ”

Lin Yiyi didn't reach out to take it, but looked at Dongfang Xu expectantly.

The latter smiled at her, raised his hand to pick up the document bag, opened it elegantly, and pulled out the stored items one by one from inside.

Lin Yiyi saw a triangular brown stone, and a black seed-like thing, plus a few brown and black hairs.

The other is a piece of fabric.

Let's say it's fabric, but it doesn't look like it, but it's just a piece of very coarse fiber.

It's a little rougher than the sacks we usually see.

It's just a big piece of the child's palm, and if you don't look carefully, you can't really tell what it's woven out of.

Nothing else.

Looking at these things placed side by side on the coffee table, Dongfang Xu was also a little dumbfounded.

He looked at the brown-black hair-like items and asked, "Old Yu, have you checked what this thing fell from?" ”

Yu Lao nodded: "I checked, but I don't have a clue, I asked the relevant biologists, and they couldn't see what the hair on the body of this thing was." ”

Dongfang Xu frowned slightly: "Is anyone studying our Longxia regarding DNA?" ”

“DNA？”

Yu Lao obviously hadn't heard of this thing for a while, and his eyes flashed with curiosity and confusion, "What is it?" ”

So, under Lin Yiyi's stunned gaze, Dongfang Xu explained to Yu Lao in great detail what DNA is.

The content of what he said can be called a textbook, so that Lin Yiyi couldn't help but give him a thumbs up when she heard it.

"This, I have to ask Xiao Chang, I haven't been in charge for many years, and I really haven't heard of such a thing."

After listening to the explanation, Yu Lao was interested, and he was not embarrassed to say that he had really never heard of it.

also praised Dongfang Xu vigorously: "Young man, knowledgeable, low-key, really a great character." ”

Dongfang Xu was embarrassed by the old man's praise, but he was not modest.

Even if this is the knowledge he gained in his previous life, it is his knowledge that is not.

Lin Yiyi said with a smile: "Brother Xu, I can't imagine that you know this knowledge in such detail, I can't even say it so comprehensively." ”

Dongfang Xu rubbed her head: "Everyone has their own strengths, why do you compare your own shortcomings with others' strengths?" ”

Yu Lao looked at the two young people, and he also felt dozens of years younger, as if he had returned to the days of his youth and getting along with his wife.

A gentle smile appeared on the old man's thin face, and he sighed: "It's good to be young! ”

"You're not old."

When Lin Yiyi heard this, she hurriedly smiled, "Look, you are sitting with us, and I haven't seen you show fatigue for so long." ”

"This is thanks to Xiaoyou's treatment, otherwise, I am afraid that my old bones would have been buried in the soil long ago."

Yu Lao smiled, his eyes looked at the few hairs, and the student baby was instantaneous......
