It didn't take long for him to see Xian Yuluo running into the upper room in a panic, kneeling in front of Yang Guang with a "plop", and repeatedly said to forgiveness: "It's all the fault of the small one, because the little one saw that the prince and the old man He were having a good time, so they thought about going to the wing room to eat first, and then returning to the prince's words......"

"Stand up and speak. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoWhat did you just find in the secret room? Yang Guang saw that Xian Yu Luo's face was frightened, his heart softened, and he asked in a slow tone.

"I was also a little confused, and I didn't find anything suspicious in that secret room, so I slacked off for a while and didn't return to the prince in time." Xian Yuluo got up from the ground, felt something from his arms, handed it to Yang Guang, and added, "It's a bamboo whistle that coaxes birds and teases dogs, I brought it with me and wanted the prince to take a look." ”

Yang Guang took the bamboo whistle from Xian Yuluo's hand, put it in the palm of his hand and looked at it carefully, it was just a bamboo piece the size of a fingernail, put it in his mouth when needed, use the tip of his tongue to blow it, and the air flow he spit out passed through the gap between the bamboo pieces, and it would make a sharp and loud whistle sound.

Obviously, this bamboo whistle is different from the clothes and food in the secret room, and it is impossible for people to store it in the secret room in advance for emergencies, and the biggest possibility is that someone hiding in the secret room left the bamboo whistle in the secret room without paying attention when leaving.

But this stone house courtyard, together with today, I have come three times, I have never seen birds in the courtyard, nor have I seen Hua Gu have cats and dogs, what is she doing with this bamboo whistle?

"Lord Wang, could this bamboo whistle be used to summon people?" Yu Juluo came to the stone house courtyard with Yang Guang today, and he felt that he didn't have half of his strength, so he intended to be courteous to Yang Guang at this time, "You think, Hua Gu usually rests alone in the front yard, and she wants to summon someone to wait in front of her or something, wouldn't it be necessary to run errands with this bamboo whistle?" ”

Yang Guang looked at Yu Juluo with a smile and asked, "Have you heard your family talk about this, or did you guess it yourself?" ”

Old Yujuluo's face turned red, and he hurriedly explained: "It's purely Lao Er's imagination, no one has ever told Lao Er." ”

"Yesterday, you led people to check inside and outside this courtyard, but did you find any living creatures?"

"This ......" Yu Juluo scratched his head, frowned and pondered for a moment, his eyes suddenly lit up, and he shouted in a trembling voice, "Bat, lord, this bamboo whistle is used to summon bats." ”

When Yang Guang heard this, his heart sank, but he didn't say anything, only lightly instructed Yu Juluo: "You take someone to the dark passage of Sweet Water Road to try, see if the whistle can summon bats?" ”

Yu Juluo obeyed the order and led a few sergeants to go for a short time, and then returned to the upper room with joy, and reported to Yang Guang with a dance: "Lord Wang, I ordered a sergeant to blow a bamboo whistle in the secret passage, and sure enough, a swarm of bats was summoned. There are so many of these animals, Lao Er killed more than a dozen in a row with a wave of his palm, but as long as the whistle does not stop, more bats will fly one after another. ”

The mystery that has been plaguing Yang Guang finally has an eyebrow: since the two fatal tooth marks on the neck of the monk Huizhen are extremely similar to the tooth marks on the back of the hand of the blood bat in the dark passage, it indicates that the monk Huizhen is likely to die under the sharp teeth of the blood bat, but what I can't figure out a few days ago is that the bats will not cross most of Chang'an City from the stone house courtyard by themselves, fly into the abbot of the Great Solemn Temple and bite the Huizhen monk to death, someone must have carried them to the vicinity of the Great Solemn Temple, and then instructed them to bite the Huizhen monk to death.

Today, the bamboo whistle that Xian Yuluo found in the secret room is most likely a tool used by Hua Gu to summon bats to kill.

Yang Guang instantly felt that he was about to incarnate Detective Conan, and from an inconspicuous bamboo whistle, he could deduce the killing of Monk Huizhen.

Something else seems wrong?

Yang Guang secretly reminded himself not to get carried away too early and ignore a crucial detail.

He waved his hand and motioned for Yu Juluo to sit down at the bottom of the head, not to make a sound, and he strung together the ins and outs of the whole thing in his mind, and sure enough, he found a place that could not be justified: although the bite marks on the back of Yu Kuluo's hand were extremely similar to the fatal tooth marks on the neck of Monk Huizhen, there was still a clear difference between Yu Juluo being bitten and nothing happened, while Monk Huizhen was bitten to death.

Could it be that there is a difference in the species of bats that Hua Gu raised in the secret tunnel?

Bat King!

Like a thunderbolt of lightning swept through Yang Guang's mind, as soon as he thought that it was very likely that there would be a bat king with sharp fangs, all the plots were right: Hua Gu carried the bat king to lurk near the Great Solemn Temple in the middle of the night, and used a bamboo whistle to blow a whistle to instruct the bat king to bite the monk Huizhen to death; On the night of the inventory of the Stone House Courtyard, she learned in advance that the official army was about to launch a crackdown on the Stone House Courtyard, and the reason why she did not escape from the secret passage with the extremely skilled red-haired young man, but chose to hide in the secret room at a greater risk for her, and leave the Stone House Courtyard after dawn the next day, most likely because she didn't have time to take this bat king who could bite people to death with her.

Yes, it must be like this.

Yang Guanghuo opened his eyes, and his eyes couldn't hide a trace of joy and relief.

"Lord Wang, this morning in the palace, what General Qu said does make some sense, even if Hua Gu can escape from this stone house, she must not be able to go far, it is better for the prince to give an order, Lao Er and the sergeants will go door to door near the West Market to carefully check, maybe she will be able to arrest her, and when the time comes, the prince will personally interrogate her for the first trial, won't he know everything?" Yu Juluo saw Yang Guang's face with joy, and hurriedly joked.

Yes, although my expectations should not be bad, but after all, Hua Gu has not heard from her so far, and I don't know where she is hiding. Only by arresting Hua Gu can we prove whether the inference I made is correct, and only then can we get more clues about Guan Zizai, the leader of Nan Chen's spy, from her mouth, maybe she is Guan Zizai herself, and I don't know. If that is the case, if he unexpectedly captures Nan Chen's spy leader lurking in Chang'an City, won't he make his father and queen mother look at him with admiration, and when the time comes, he will ask them to leave the town and merge the state, and they will not refuse.

Yang Guang thought about the best result of the investigation in his heart, and completely forgot that at present, he did not even verify the crucial fact of whether Hua Gu escaped from the secret passage that night, or whether he hid in the secret room first, as he deduced, and slipped away with the Bat King at dawn the next day.

"How is it, lord, give the order quickly." Seeing Yang Guang smiling, Yu Juluo did not veto his proposal, and urged tentatively.
