Without hesitating that the ground was full of ashes, Ye Qing lay directly next to the traces of the charred corpse.

According to He Wen's command, he was in the posture of Ziyuan's tragic death at that time.

There is a comparison of references.

The fog of this case in He Wen's mind before suddenly dissipated a lot.

He followed Ye Qing's spine and looked in the direction of the west-southwest:

"According to what we guessed before, after the tragic death of Ziyuan Zhenren, if you look in the direction of the murderer."

"Then his line of sight should be judged by the direction of the lumbar spine."

Ye Qing, who was curled up on the ground, agreed:

"Yes, according to what you said before, when people are injured and dying, they will protect the vital points."

"The fire must be very painful, so the head will shrink, and you should look in the direction of the lumbar spine."

Then.

He Wen looked to the northeast again and said, "Also, according to another speculation before, Ziyuan Zhenren was injured and wanted to chase the murderer, and after crawling on the ground, he crawled back to the center of the main hall due to the fire. ”

"Then in addition to crawling back from the southwest, turning around and looking at the direction of the murderer's departure again, it is possible that he crawled from the northeast."

"The rest is the place where Ziyuan Zhenren is born, what may exist."

"However, when I came to investigate, there was nothing unusual about this place."

After a pause, He Wen continued:

"In the southwest direction, the most edge is the wall of the Sanqing Palace, and then a foot and a half away, there is a pillar that people hold."

Then, he looked in the northeast direction, frowned slightly, and said:

"To the northeast, there is also a pillar, and there is the shrine platform dedicated to the Sanqing Palace, and then the wall of the Sanqing Palace."

After speaking, he helped Ye Qing up.

His hands pressed on the stone slab full of ashes, supporting Ye Qing, who was standing up, his brows furrowed slightly, and he pointed to the two stone cracks in the stone bricks under him and said:

"Brother He, take a look at this brick crack."

He Wen, who was squatting down, looked at the brick crack of Ye Qing's finger.

The white marble of the Sanqing Hall is the base, and it is paved tightly, and it is not easy to see that there are brick joints.

After a year and a half of sun and rain, the ground should be full of ash and all the brick joints, and they should also be filled in, so you can't see it.

But next to the white marble brick where Ye Qing was lying just now, next to the white marble brick with the marks of the charred corpse, the stone crack between the two pieces was actually revealed.

Although the stone crack was intermittent, it was impossible to hide it in the eyes of two people with excellent eyes, looking at it on its stomach, and the light of the lantern fire.

The two of them, who had been reasoning for a long time, thought of various possibilities, and couldn't help but look at each other and smile bitterly at this time.

He Wen covered his forehead speechlessly, and said softly: "Good guy, while searching alone, we stopped at the scorched corpse imprints. ”

"I deduced the impossible place before, so I didn't look at it carefully, I didn't think about it, and it was really here."

Ye Qing didn't feel dirty, took out a copper coin from his arms, lay on the ground, scratched along the crack in the stone, and said with a smile:

"It rained a while ago, and the ashes here were washed again, and it is estimated that the ashes in the stone crevices seeped into the secret passage, and some stone crevices leaked out."

He Wen, who thought about it, said loudly: "Indeed, when I came to see it, there was no rain in those days, so I guess I missed it." ”

After speaking, He Wen also lay down, took out a copper plate from his arms, and scratched the stone crack.

There is a cavity under the stone crack, and the ashes of two stone bricks are glued together in the stone crack, and with the touch of the copper plate, it does not need much force, it will be broken and fallen, and there is little stubborn solidification in the stone crack.

The two of them had neat hands and feet, and soon under the scorched corpse marks, the stone cracks around a three-foot-long white marble brick were revealed.

He Wen's fingers tapped on the stone bricks, and there was a dull sound.

He knocked on the stone bricks next to him again, and the sound was so dull that he couldn't hear the difference at all.

Ye Qing frowned and said: "This voice, I can't hear that there is a secret passage below, this brick should be very thick." ”

He Wen, who nodded his head, was puzzled:

"How was such a tightly knit stone brick picked up without a point to draw on?"

Ye Qing, who didn't know how to do it, patted the ashes on his hands, and spit out a turbid breath:

"If someone with unparalleled strength could top it from below, it might be possible to lift this stone, but from above, it's really impossible, maybe there's some special mechanism or something."

Organ?

He Wen, whose eyes lit up, pointed to the southwest and northeast, and said quickly:

"Maybe the agency is on both sides."

The next moment.

He Wen's brows furrowed again, rubbing his chin and saying, "No, no, no." ”

"If this secret passage is really under this stone brick."

"This white marble brick is three feet square, that's not an ordinary weight."

"The murderer killed Ziyuan Zhenren, jumped down the secret passage, and then moved against the stone bricks, which will definitely leave obvious scratches."

"But let's see, there are no scratches on the stone bricks around here."

"Unless there's a mechanism under the passage that can move the stone bricks."

"In addition, that is, the murderer hurt Ziyuan Zhenren and stole the Zijin Ding."

"Because the murderer has a close relationship with Ziyuan Zhenren, even if Ziyuan Zhenren is injured by someone close to him, he is willing to help him cover up the crime, drag his injured body, and close the secret room?"

Careful speculation, all kinds of possibilities derived.

Ye Qing, who was in contact with such a difficult mystery for the first time, felt a little dazed, and his brain was not enough.

He shook his head and said:

"Solving the case, you are an expert, you think first."

"The main hall was burned down, the columns and beams were burned down, and the mechanism could have been destroyed."

"Brother Yan has a lot of strength, I'll see if I can find a way to remove the stone bricks from above."

"Now all our speculations are secret passages under this stone brick."

"With a secret way, our reasoning can be established, and other possibilities can be ruled out."

The well-organized addition was approved by He Wen.

"Indeed, you are right, all reasoning is based on secret passages under stone bricks."

"I'm going to inspect the remaining pillars and beams."

Ye Qing is not afraid of dirty, but he sells noodle soup all year round, and the habit he has developed makes him clap his hands and the ashes stained on his gray and white cotton clothes.

He raised his head and looked at Yan Sandao around him vigilantly:

"Brother Yan, come here and do me a favor!"

Yan San remained vigilant, took a step, his head twisted uneasily, and his eyes scanned the surroundings.

When he walked to Ye Qing's side, he retracted his gaze and said:

"Help, you say."

Ye Qing pointed to the stone brick under him and asked, "Brother Yan, do you have a way to lift this stone brick?" ”

Yan San looked at the stone crack that was not much thicker than a hair, and his brows furrowed.

He squatted down, rubbed his cheeks, and said:

"Brother, you are embarrassing my Yan San!"

"This stone crack is so thin that you can't even put your fingers into it, and you can't use your strength."

Ye Qing, who knew that this was the case, sighed helplessly:

"Hey, I know too, this ......"

The words are not finished.

Seeing Yan San kneeling on one knee, taking a deep breath, his right hand, which was originally touching his beard, turned into a fist, raised it violently, and smashed it fiercely towards the stone bricks in front of him.
