Coco Ding said: " Now the village is building fortifications, and the market that was very lively before was not as crowded as before, so it is easier for me to observe than before, because now many people from other villages know at a glance, unlike before, there are more people but it is easy to miss a lot of people, so I stay alone in the market to pay attention to those foreign businessmen, let Yuan Qin and Da Jun walk back and forth on the route to the two inner city gates, to observe whether there are people from other villages, the two main roads are basically to and from the soldiers and villagers who participate in the defense project, there are not many outsiders, it is easier to monitor, at the end of the day, I just met with them, and I did not see any suspicious characters。 ”

Kai Hao nodded and said, "Xiao Wen, you come to me early tomorrow morning, and I will tell you what kind of observations to make." ”

Ding Wen nodded and said, "Okay." I still have a little idea. ”

Kai Hao said: "Speak, tell me immediately if you have any thoughts in the future." ”

Ding Wen said: "Kai Xuan, do you think that suspicious people will be mixed into the people who participated in the fortifications because they are afraid of being discovered? Now there are people who participate in the fortifications everywhere, divided into hundreds of groups, and because they do their own things with each other, will the bad guys be allowed to get in?"

Kai Hao nodded thoughtfully and said, "This can't be said to be impossible, Xiao Wen, your suspicion is very good." ”

Chen Meng said: "The leader of each group should be able to tell if it is his own person, right?"

"If there are many groups working together, the team leader will only pay attention to his own team members, and it is impossible to notice who the other groups are, so as long as they are deliberately mixed in the crowd, it is really difficult to find out," Kai said. ”

Chen Meng frowned and said, "That's quite annoying, there are thousands of people participating in the defense project now." ”

Kai Xuan looked at Ding Wen and said, "Xiao Wen, you look for a few more people, we children are generally not paid attention to by bad guys, we can play at the defense site and take the opportunity to observe if there are any suspicious people." I can first greet the group of five and ask them not to deliberately care about the little friends we sent. ”

Ding Wen nodded and said, "This is okay." I'll find some more obedient friends, and everyone will disperse to observe. ”

"Be sure to be safe. If the enemy finds that someone is following, he will not show mercy, and if it wasn't for the big and fast yesterday, we would have died. ”

Ding Wen swallowed and said, "I know, I'm most afraid of death." ”

Chen Meng said: "It's better for you to work in a group of two, one to take care of, if you are alone, no one will know what happened." ”

Kai Hao nodded and said, "Da Meng is right, no one doubts a few friends together." ”

The three of them discussed for a while, Lao Kai and Hongyu came back, and Ding Wen went home first, saying that he would be scolded by his parents if he went back late.

Hongyu was quick with her hands and feet, and quickly made dinner, and everyone sat around for dinner.

Although they have been busy for a day, Lao Kai and Hongyu are not too tired, because the labor intensity is well controlled, so that the villagers will not feel tired.

I heard that Xiao Xuan would be sent up the mountain to Wenlu tomorrow, Hongyu was naturally quite reluctant, but there was no way.

After dinner for a while, Wan Zhiwen's figure appeared at the gate of the courtyard, he came to find Kai Luxury, he brought his daughter Wan Qinwen over, Xiao Xuan happily went to see the bamboo cat with Wan Qinwen.

Kai Hao took Wan Zhiwen and Chen Meng to his own room, sat down at the wooden table by the window, and Hongyu made them a pot of hot tea before going out and closing the door.

Kai Hao smiled and said, "Uncle Wan, are you already able to make crossbow arrows?"

Wan Zhiwen was stunned for a moment, smiled and said, "Kai Hao, don't think too much about me, those few crossbow arrows are not simple." ”

He took a sip of tea and said, "I disassembled two crossbow arrows, and the principle can basically be understood very clearly, but if you want to copy it, it is impossible. ”

Kai Hao and Chen Meng were a little surprised. They thought that there was no problem with the production of crossbow arrows.

Wan Zhiwen said: "The parts inside are very precise, and it is difficult for us to make them under our current conditions, especially the materials of many parts cannot be found in the private sector at all, only the official ones have them, and only the official smelters can make them." ”

Kai said depressedly, "Then you can't make crossbow arrows?"

Wan Zhiwen smiled and said: "Yes, but the power and range are greatly reduced, because the structure of those two crossbow arrows has brought me a lot of inspiration, I can use the materials we can find to process parts and make seven consecutive crossbow arrows, but because the power of the spring and rubber band is only one-fifth of those crossbow arrows, the effective range can only range from twenty to fifty meters." ”

When Kai Hao heard that he could make crossbow arrows, his heart was already very relaxed, and he said with a smile: "Uncle Wan, I think fifty meters is enough to have an effect." ”

Wan Zhiwen nodded and said, "This is just my prediction, when I make the first batch of crossbow arrows, we will find a place to test the arrows together." ”

Chen Meng smiled and said, "Yes." If I can in the future, I will also equip it with crossbow arrows. ”

Wan Zhiwen whispered: "This thing is not fun, the three of us must keep it strictly secret, after the experiment is successful, I will hurry up and make a batch of it, and take it out when needed." ”

Kai Hao thought for a moment and suddenly said: "Uncle Wan, those crossbow arrows are very portable, if the ban is opened in the future, it is very convenient to carry them except for tasks, I wonder if the imitation crossbow arrows are also portable?"

Wan Zhiwen shook his head and said: "Using the existing materials, it can't sit so portable, and every part can't be so precise, so the body size is enlarged at least twice the length, including the length of each crossbow arrow, but compared to the crossbow arrow I designed myself, it is much lighter." ”

Kai Hao nodded and said, "That's not bad, if these crossbow arrows are made, they can only be hidden in the arsenal for the time being as an alternative weapon when there is nothing to be done in the end." ”

Wan Zhiwen nodded and said, "I haven't heard of anyone in the Colony City daring to use crossbow arrows. No matter how turbulent the situation is, you can't reveal a little bit of information until you are absolutely sure, otherwise you will destroy the whole village. ”

Kai Hao's heart suddenly tightened, and he thought of Ah Shan and the old demon.

If they had also come to Shuikou Village at the same time and knew that those five people had brought crossbow arrows, then they should have guessed that the crossbow arrows were captured by Shuikou Village by now, and what would have happened if they reported the crossbow arrows to the barracks?

Wan Zhiwen saw his face change, and unconsciously asked, "Kai Hao, what did you think of?"

Kai Hao hesitated for a moment, he didn't want Wan Zhiwen to know about the existence of Ah Shan and the old demon, but he didn't feel the need to hide Wan Zhiwen.

Kai Hao said: "I'm worried that those five people still have accomplices, will the accomplices tell the barracks about the crossbow arrows?"

Wan Zhiwen's eyebrows furrowed and then stretched, and said: "Absolutely not, the military camp is very strict with the verification of the person who reported the information, once the information is false or the identity of the person who reported the information is problematic, he will be sent to the mine." ”

Kai Hao nodded, slightly relieved.
