In order to go into the water to explore the mechanism in the water, Du Qingshan took off his cyan smock, only wore a moon-white single coat, and came to the hall on the first floor, where he happened to meet Song Guichen and Xiaoyi coming from the backyard.

Song Guichen saw that he was dressed coolly, and quipped: "Are you preparing to go into the water?" ”

"Xiaochen is so smart." Du Qingshan smiled slightly, "Do you want to go into the water with me again?" ”

"Don't!"

"It's heartless."

Song Guichen looked at Gu Yi, who was walking behind, and greeted him: "By the way, Brother Gu, since Han Song said that Xiao Yi was locked up in the state capital prison, didn't he say who he should be in the state capital?" ”

Gu Yi and Du Qingshan glanced at each other, unexpectedly that she also suspected that Han Song had an internal response in the state capital.

Song Guichen didn't know what they were talking about upstairs, so she didn't understand what they meant by their tacit understanding and smiling, she thought in her heart what Fang Cai Xiaoyi said, she and Meng Lou Chang were locked up in the state government prison, and she just wanted to ask Gu Yi what was going on.

Gu Yi told Song Guichen about the analysis with Du Qingshan, Song Guichen was speechless for a while, thinking that for so many years, every time she went down the mountain and came to the Towering Cui Building, Han Song always asked with a smile:

"Miss Song, did you secretly go down the mountain to fight for the tooth sacrifice again?"

At that time, she, like everyone else, thought that Han Song was a kind and affectionate person.

Unexpectedly, in less than two months, Han Song's image in her heart has undergone such earth-shaking changes.

"Han Song was reluctant to speak, and the Criminal Division had to detain him for a few days." Gu Yi half sighed and half comforted, "After entering the Criminal Division, no matter how tough a man is, I'm afraid he won't be able to stand it, I think he will confess sooner or later." ”

The two were talking here, and suddenly heard a "plop", Xiaoyi excitedly shouted: "Come and see, Du Qingshan has slipped off the bamboo pole!" ”

Because Song Guichen opened his mouth and closed his mouth to call Du Qingshan's name, even with Xiaoyi, he only called "Du Qingshan, Du Qingshan".

Song Guichen and Gu Yi came to the corridor, but they saw ripples on the surface of the lake, but they didn't see Du Qing's shirt at all.

Only Xiao Yi was pleasantly surprised: "Brother Zhou's diving skills are powerful enough, but I didn't expect Du Qingshan, a native of the Central Plains, to have such great water skills!" She danced with joy, pulled Song Guichen and said, "Xiaochen, you really picked up a treasure." ”

Song Guichen gave her a burst of chestnut: "Little brat, it's rude to call adults by their names, understand?" ”

Xiao Yi said dissatisfiedly: "Doesn't Xiaochen also call Brother Du's name." ”

"I-" Song Guichen was about to argue, Gu Yi suddenly looked surprised, and hurriedly pulled Xiao Yi, "Xiao Yi, what did you just say?" ”

"I ...... I call Du ..... Brother Du's name? ”

"Not that, first sentence."

"Eh, Brother Zhou is a great diver?"

"That's right! That's it! Gu Yi nodded, let go of Xiao Yi, and asked gently, "Brother Zhou you are talking about, but the bartender Zhou Qiang?" ”

"That's right, Brother Zhou's diving is amazing, what is wrong with the merchant ships in Towering Cuilou, which is often repaired by Brother Zhou's diving; Even for things such as dredging the lake and setting up fireworks mechanisms in the lake, the craftsmen invited by the Towering Cuilou sometimes come to ask Brother Zhou for help. ”

Song Guichen listened, and suddenly realized what Gu Yi was thinking, and was about to tell him that it was impossible, when a head poked out of the bamboo pole in the lake, and Du Qingshan threw up a bunch of ropes, floating in the water and said:

"Brother Gu, this is the remnants of the rope on the iron hook ten zhang away from this bamboo pole facing west."

As he spoke, he dived to the surface again.

Gu Yi put the rope thrown up by Du Qingshan on the railing of the cloister to filter the water, looking at the calm lake, not knowing what he was thinking.

Seeing this, Song Guichen knew that he was thinking about things, so he stopped talking, stood behind Xiao Yi, and looked at the lake.

After a while, Du Qingshan resurfaced: "An iron stake was driven under the lake, and several bamboo poles on top of it were set on each other and then came out of the water, and it was difficult for manpower to pull them out, Xiaochen, lend me your scimitar." ”

Song Guichen didn't have time to ask him how he knew that he was carrying a scimitar, so he quickly took out the scimitar and was about to turn over the railing to send it to him, but Du Qingshan laughed in the water: "Xiaochen, you still want to go into the water with me." ”

When Song Guichen heard this, he glared at him silently, returned to the corridor, and threw the scimitar directly over.

Du Qing's shirt avoided it and caught it easily.

"Thanks!"

As soon as the words fell, the man disappeared again.

After a while, I only heard the bamboo pole "rattle" twice, swayed a few times, and then fell westward.

Du Qingshan came out again, dragged the bamboo pole to the shore, and went ashore.

Gu Yi had already ordered someone to prepare a set of clean clothes, and he hurriedly came with towels and clean clothes: "It's hard work Brother Du." ”

"Nothing." Du Qingshan took the towel and wiped the water on his face, "I'll go change my clothes first." ”

Saying "Ah Ngai", he sneezed loudly, took the clothes prepared by Gu Yi and went upstairs.

Only then did Gu Yi turn around and check the bamboo pole that Du Qingshan had dragged up

This bamboo pole is indeed as Du Qingshan said, and it is connected together one by one, and it is ten zhang long.

Gu Yi looked up at the Towering Green Building, the first floor of the Towering Green Building is two and a half zhang high, the second and third floors are two and a half zhang high, plus the foundation is one zhang higher than the surface of the West Lake, the eaves of the third floor are about seven and a half zhang away from the water surface.

The water area in the west of the building is slightly shallow, about one or two zhang deep, the bamboo pole is far away from the towering green building, if you want to hit the eaves of the third floor by the bamboo pole, the distance between the bamboo pole and the iron hook of the borrowing force should be nine zhang, and the length of the bamboo pole should exceed this number, calculated, the bamboo pole of ten zhang long, almost just hit the eaves of the third floor of the towering green building.

Gu Yi was amazed, such a precise and ingenious assassination plan, the designer also took a lot of effort.

The incense burner poison bureau is to use the rare and mysterious killing of the other side of the flower and the other side of the leaf to kill invisibly, as long as you know the anthers of the other side, you can think of using its characteristics to poison.

And this bamboo pole mechanism is completely based on the ingenuity and ability of the person who designed the mechanism.

"Brother Gu, have you found anything?"

Gu Yi opened his mouth with undisguised praise: "The design of the bow and crossbow on this bamboo pole is exquisite, I have never seen it." ”

Song Guichen took a closer look, and saw that the top section of the bamboo pole was tied with a bow and crossbow with refined steel wire, and there were three card slots on the bow and crossbow, which were supposed to be used to place bows and arrows. Peculiarly, the crossbow string on the bamboo pole is not made of ox tendon used in ordinary bows and arrows, but steel wire.

Although Song Guichen was not proficient in weapons, he also drew a bow and hunted prey.

At this time, he knew that this bow and crossbow was by no means an ordinary thing, and he couldn't help but praise: "The person who made this mechanism is so powerful." ”

Gu Yi nodded: "The master is in the people." ”

Xiao Yi was in a daze, not knowing what they were praising them, she just thought it was fun.

Tilting his head and looking at the bow and crossbow for a long time, Xiao Yi pouted and said, "This mechanism is not as good as my windmill." ”

Gu Yi looked at Xiao Yi again: "Xiao Yi, did your windmill be given to you by Brother Zhou?" ”
