The whole black sleeve arrow is only ten centimeters long, and the chopsticks are thick. The tip is pointed, and the top is the pattern that hangs out when it is forged, and those lines spread from the tip like a pattern. Those lines are Rong Bai's blood grooves, which are different from those men's sleeve arrows in Linjiang County, which only have two or three blood grooves, and Rong Bai's sleeve arrows are full of blood grooves.

Similarly, the body of the Hidden Arrow is not the same as the normal one.

The body of the arrow is spiral-shaped, and every protrusion is very sharp. It is conceivable that as long as this Hidden Arrow hits the target, it will definitely cause the most damage.

Fifteen Hidden Arrows lay side by side on the plate next to the bucket, and Rong Bai's hand reached out to the parts scattered next to him.

That's a crossbow part.

is also different from the crossbow in ordinary people's cognition, the crossbow made by Rong Bai this time did not use a bowstring at all. The half-foot-long lumen with a highly elastic spring behind it does not require a little force at all, and it is only necessary to reload the sleeve arrow, as well as pull the trigger.

When it was all dark, Rong Bai went home with the prepared sleeve arrows.

Hengqing stayed in the study for a day, and didn't go to the restaurant in a wheelchair until it was dark. When it was time to eat, Rong Bai hadn't come back yet. He had to find someone to remind Rong Bai, Rong Bai had been at school for a long time recently.

"Hengqing, why haven't you eaten yet?" As soon as I entered the restaurant, I heard Rong Bai's voice.

As soon as Hengqing turned around, he saw Rong Bai striding towards the restaurant, holding a box in each hand.

Since the school opened, Rong Bai always brought some strange little things back. Hengqing knows that these little things have a strange style, but they are very practical. Therefore, it is not strange to see the box in Rong Bai's hand.

"Hengqing, this is for you." Rong Bai put down the box, washed his hands, and handed the information he had been carrying today to Hengqing.

"Mrs. Wen is so efficient?" Hengqing was stunned.

Hengqing knew that Wen Wan was a strange woman. However, this is limited to meek business talents. But obviously, as soon as this information is taken out, it shows that Wen Wan not only has amazing business talents, but also has unique views on the political situation. In front of Rong Bai, Hengqing only sighed and put away the information.

beckoned Rong Bai to eat.

After eating, Rong Bai followed Hengqing to the study again.

Hengqing must study the information brought back by Rong Bai tonight, so when he saw Rong Bai who followed him into the door, Hengqing was a little puzzled. It stands to reason that at this time, Rong Bai should be ready to rest.

"Xiaobai?"

"I'll be gone in a moment." Rong Bai looked left and right, and there was no one else, so he put the box he brought back next to Hengqing's wheelchair, turned around and closed the door.

Hengqing looked at Hui Rongbai's back suspiciously, then turned his head down and looked at the box at his feet. Both boxes are not large, only the size of a book. The thickness is only about three inches. Looking at Rong Bai's performance, there are still very important things in this box. Could it be other information found by Mrs. Wen?

The answer was soon revealed.

What Rong Bai brought back was obviously not any information.

The pure black parts were quickly combined into two crossbows in Rong Bai's hands. The crossbow bow is very small, the width is only the thickness of an adult's arm, and the length does not exceed the length of the forearm Rong Bai After it was done, he picked up Hengqing's arm and compared the size, which was just right.

"It's a Hidden Arrow." Rong Bai explained while showing the installation method: "This is not like Linjiang County at that time, there is no danger, I can rest assured if I put you at home." In the voice, Rong Bai's voice was very clear: "Even if you are left at home, I don't know when someone will come to the house to hurt you." ”

"Hmm." Hengqing's gaze softened to the extreme.

"Hidden Arrows are to protect yourself, and you must equip them with Hidden Arrows every day when you get up in the future." After seeing Hengqing nodding, Rong Bai opened another box. The contents of this box are another picture.

"I'll help you modify your wheelchair."

"Okay."

Rong Bai's transformation of Hengqing's wheelchair is still a weapon system. Although he has successfully manufactured thermal power generation equipment and power storage equipment in the workshop, Rong Bai has not yet used this in Hengqing wheelchair. It is still a cold weapon launcher, and Rong Bai is installed in the reserved space of the left and right handles.

Hengqing touched the handle, and there was a bulge on the top side.

"It's only used when there's no way, and there's no way to make it increase the hit rate right now." There is currently no steering device, so even if Rong Bai wants to increase the sighting device, it is not realistic. However, sometimes, the device in the wheelchair should also save Hengqing's life. If there is such a thing as assassination again, Hengqing will be able to save himself.

You must know that in the storage device in the handle of Rong Bai's wheelchair, there are hundreds of small arrows on each side.

The small arrows the size of toothpicks may look inconspicuous, but once they hit the target, their strange shape and design for increased damage can instantly destroy the target's musculature. Even if you are unlucky, you can reduce the opponent's combat effectiveness.

Rong Bai finished installing the device, got out of the way, and motioned for Hengqing to give it a try.

Hengqing's right hand pressed on the bulge, and there was a faint popping sound, and after that, a small hole appeared in the wooden door frame in front of him. Rong Bai was very satisfied and reached out and poked the small hole, poking off a lot of debris.

It looks like it's just a small hole, but in fact, the structure inside has been destroyed a lot.

Turning around, he returned to Dao Hengqing's side: "In order to avoid accidental injury, there is a safety device here." Rong Bai squatted down and showed a button at the lower end of the handle: "This button, when it is convex, the safety device is closed, and when it is concave, the safety device is turned on." ”

After speaking, Rong Bai stretched out his hand and pressed the two bumps down.

Hengqing stretched out his hand, pressed the button on the handle again, and found that nothing could be launched this time.

"Xiaobai's mechanism is really exquisite." Hengqing sighed from the bottom of his heart.

But it's more of a hard thing to say. Rong Bai has always pursued the principle of doing it if she doesn't accept it, and fighting head-on is the battle that can make her happy. However, for his own sake, Rong Bai has obviously begun to study hidden weapons.

"The one that can protect you is the subtle mechanism." Rong Bai replied.

"This kind of thing, Xiaobai needs it more." Hengqing looked at the sleeve arrow on his wrist and spoke.

Compared with Hengqing, who stays at home more times on weekdays, Xiaobai has a higher probability of encountering danger on weekdays.

"I have, don't worry." Rong Bai rolled up his sleeves, and there were this kind of weapons on both forearms, and even on his elbows, there were other things: "I have to send a few sets to Feiluan." Rong Bai clapped his hands, turned around and was about to go out.

Heng Qingmu sent Rong Bai away, stretched out his hand to open the information that Rong Bai brought back, and after only one glance, his face was a little ugly.
