"And then we found the feather that we didn't know what species it was." Lao Yue Zangzang added.

"Yes, I forgot that you said that, and I forgot that there was still this stubble." Chu Yu patted his head and said, "I already knew that I would have given the feathers to Master Miao, and asked him to help us distinguish what kind of bird's feathers this is." ”

"This is not in a hurry, anyway, I will have to meet Master Miao later, and then I will come to the place we marked for a trip, and it will not be too late to give it to him by then, and I will study it slowly on the way." Lao Yue said.

"That's right." Chu Yu nodded in agreement with Lao Yue's point of view, and then looked at the birds around him.

"Huh???"

"What's wrong?" Chu Yu asked after hearing Lao Yue's puzzled voice.

"Have you noticed that there seems to be something hanging from these trees?" Lao Yue said as he looked along the trunk of the tree.

"It's kind of like a syringe for supplementing plants, eh...... There is also a number on it, 76. Lao Yue said in detail: "I just noticed this thing!" ”

"There should be no problem, after all, this is also a very common situation, and trees lack nutrients to rely on this nutrient solution to avoid the yellowing of trees and internal shrinkage." Chu Yu said with a look that this was a common situation, don't be surprised.

"If you say that, it's not so suspicious." Lao Yue said indifferently: "However, this one of his is not occasionally on a few trees, but there is such a sign on every tree, but some of them are just nutrient solutions for injection." ”

"Maybe it's for the sake of identifying that the tree is sick." Chu Yu said his guess.

"Well, that's ...... in the past!" Lao Yue suddenly stopped his words and stared in one direction: "You just found something good!! ”

"What, found a clue?" As soon as Chu Yu heard Lao Yue's tone, he estimated whether he had found something related to the 'Brain Eating Maniac'.

"I found a chickadee." Lao Yue said.

"What's wrong with finding out the, it's not normal here...... Is it? Chu Yu said naturally, but the more he said it, the more he felt that something was wrong there, "You mean?" It's the kind of 'Brain Eater'!! ”

"yes, that's it." Lao Yue pointed to the tree not far in front of him, the whole head was black, with a large white spot on each side of the head, the upper body was blue gray and the lower body was white, and there was a broad central longitudinal stripe on the chest and abdomen, which was connected to the chin and throat black.

"It's really big." Chu Yu cautiously walked under the tree where the big were found, and looked at this bird with the same appearance as the online encyclopedia introduction.

"I'm not afraid of life." Lao Yue floated up and kept parallel to the big, and teased: "Although it is not afraid of life by nature. ”

"I can't see you again, I'm afraid of a hammer." Chu Yu couldn't help but complain.

"No, no, no, I mean you stand under a tree and it doesn't even react." Lao Yue was a little speechless, and Chu Yu understood.

"I guess what it thinks in its heart is that this fool under the tree can't go up the tree, so he can only watch Uncle Ben's heroic posture under the tree." Chu Yu said with a smile.

"You're stupid!" Lao Yue sat on the branch and looked at Chu Yu under the tree and said.

"You have the ability to come down, I'll reason with you." Chu Yu heard Lao Yue mock him like this, and immediately said unhappily.

"I think you're really wise." Lao Yue sighed and said, "The big are all here, can't you think about why??? ”

"Well...... Chu Yu pondered seriously for a moment and said, "Because the food here is good, it comes in from the outside to rub the food and has a long body." ”

Lao Yue patted his forehead and said, "It's over, you definitely took the wrong medicine today......

"Just kidding, don't be so serious...... Chu Yu suddenly said seriously: "If you're serious, you'll lose." ”

"Can you give me a long knife?" Lao Yue asked.

"What?" Chu Yu said vigilantly.

"I'm going to cut you." Lao Yue sighed, he really didn't know why Chu Yu, this kid, suddenly changed.

"Haha, what are you kidding...... Chu Yu laughed and said, "There is nothing else besides this one?" ”

"So far, I have seen such a ......" Lao Yue suddenly had a mouth next to this big that did not look natural.

There are obvious traces of artificiality?!!!

"I think I've found something interesting!" Lao Yue stroked the big with a smile, "If it weren't for this little guy, I wouldn't have discovered the mystery here." ”

"What's wrong?" Chu Yu raised his head and looked at Lao Yue: "You came down to talk!" I'm sour!! ”

"Haha, then you can look up for a while!" Lao Yue said with a smile. Get up and continue to float towards the other trees.

And so it was! Lao Yue was even more sure of his judgment in his heart.

"I discovered the secret of the Bird Park." Lao Yue easily returned to Chu Yu and said.

"You say first, I'll rest my neck." Chu Yu casually found a place where he could lean against the tree and sat down.

"I told you before, every tree has a number on it, haven't you forgotten?" Lao Yue asked.

"Of course not, but I think it's all normal." Chu Yu replied.

"But I feel like this number is the number of these big." Lao Yue explained.

"To the number of the big, you mean there are big on all the trees here?" Chu Yu asked in surprise.

"Not really, but I found that there is a big on several trees, as if it is fixed, and there will only be a big on each tree, as if it is customary, and no one will intrude into other people's territory." Lao Yue said.

"How is it possible, how can they have this kind of awareness, the big is a social animal, in this case...... It can only be interfered with by human factors. Chu Yu suddenly analyzed.

"Yes, you know." Seeing that Chu Yu finally understood what he meant, Lao Yue finally sighed and said, "Now that the thread has been found, the next step is to rely on us to disassemble the thread step by step." ”

"Well, so let's go over there for now!" Chu Yu pointed to the northeast of the bird park and put it down, the position that Lao Yue had specially explained before.

Maybe there's some hidden secret there!

"Okay, let's go. I looked in the trees again, and the numbered big were gone. Lao Yue said.

"Lao Yue, you said that this big is obviously a beneficial bird, why did anyone think of using it to transform it into a killing tool." Chu Yu was puzzled by such a move, although people who understood miracles were lawless and would do everything.

"The more ordinary you are, the less noticeable you are, just like a killer, the more ordinary you are, the less likely it is for people to remember your appearance, so that you can leave in style after completing the assassination." Lao Yue explained: "This is also the same reason. ”
