While joking with Lin Yiyi, Yu Lao set his eyes on those unknown hairs, and instantly turned into a curious baby who was eager to learn:

"Dongfang Xiaoyou, according to what you just said, as long as we have these things, we can find out what species it comes from through that A identification?"

“DNA。”

Lin Yiyi was on the side to help the old man remember this new term.

Yu Lao glanced at her gratefully, and continued to look at Dongfang Xu expectantly.

Dongfang Xu: "Theoretically, this is the case, but the key is to see if there are any genetic specimens with very similar similarity in our gene pool. ”

"If you don't have this specimen, you can't find out what kind of creature it came from."

Yu Lao suddenly said: "Xiaoyou is right, I am too anxious." ”

"If our Long Xia really has this technology, the Dragon Pavilion people should know it in advance than anyone else."

"Since they have spent so much time and energy not figuring out the origin of this thing, I don't think there is anything at present."

Dongfang Xu nodded: "At least there is no record of this yet." ”

Lin Yiyi sat on the side and tasted tea without taking a sip, quietly listening to the conversation between the old and the young, and was not in a hurry to participate in it.

Old Yu's eyes fell on Dongfang Xu and said solemnly: "Xiaoyou, if you have any good suggestions, you might as well say it, and the old man will see if the Dragon Pavilion can do it." ”

Dongfang Xu was not in a hurry to express his opinion, picked up the things he took out of the document bag, and observed them carefully.

The room fell silent for a moment, and no one bothered him.

After a long time, Dongfang Xu took a deep breath, put down the last thing in his hand, and looked at Yu Lao with a solemn expression.

"How?"

Yu Lao looked at Dongfang Xu expectantly, "What can you see?" ”

Dongfang Xu pondered for a moment before he said with a solemn expression: "Don't say where these hairs come from, just these three things ......"

As he spoke, he reached out and picked up the brown triangular thing, flipping it back and forth: "Like this, it's kind of like our buttons." ”

"But it's not exactly like it, whoever has such a sharp button on his body is only afraid of being scratched by it at all times."

As he spoke, he sent the items in his hand to Yu Lao and said, "Yu Lao, look, there are three tiny holes in each of these three corners. ”

He raised his eyelids slightly to look at Yu Lao and said, "These holes are so small that they can't even penetrate our thinnest thread at present." ”

Although Lin Yiyi didn't come over, at such a close distance, her divine sense could still easily probe the past.

Sure enough, on the three corners of the triangular item in Dongfang Xu's hand, three extremely thin holes were found, and I don't know what they were for.

Dongfang Xu looked at Yu Lao and asked, "I don't know if Yu Lao, have you studied the effects of these holes during this period?" ”

"Or rather, analyze the material of the object."

Yu Lao took a serious look at the item in his palm, and then said, "I believe that they have studied these things. ”

As he spoke, he picked up the hand-cranked phone next to him and prepared to call.

At this time, Chang Xingxia pushed the door and entered: "Old Yu, all the formalities of the Oriental Protector have been completed." ”

Seeing him come in suddenly, Yu Lao picked up the microphone and put it down again: "Xiao Chang, you came just in time, I have something to ask you." ”

Chang Xingxia smiled and politely handed over the things he was holding to Lin Yiyi.

Lin Yiyi smiled at him, and took over the tokens, badges and other items belonging to Dongfang Xu with both hands, but did not disturb their conversation loudly.

While handing over the things to Lin Yiyi, Chang Xingxia hurriedly said respectfully to Yu Lao: "Yu Lao, if there is anything, you can ask." ”
