In fact, Zhou qiuchu's expression is not very accurate. What she said leaves traces is not a literal meaning. If you give medicine to Watanabe changgu, it will leave traces for him to find.

However, Chen Hui and some of them all understood what Zhou qiuchu meant. What Zhou qiuchu said is that drugs that make people comatose will remain in the human body for some time. Even if the effect is over, people who are drugged will probably feel sick when they wake up!

In this way, Watanabe Nagoya is very likely to find that he has been drugged. Even if he changes the bronze tripod, he can't tell whether it's true or not, and he may be suspicious.

Chen Hui laughed and said, "it's not my boasting. The medicine I made will not only make people unconscious, but also make people feel comfortable after the efficacy disappears. People who have been drugged will not notice that they have been drugged."

After a pause, Chen Hui added: "the best way to use this medicine is to let Watanabe changgu fall into deep sleep after he falls asleep. After the efficacy disappears, he will never find it when he wakes up in the morning!"

After Chen Hui explained the efficacy of the medicine he was able to prepare and the time he imagined to take it, he Yanwei pondered for a moment and said, "it's feasible!"

Who knows, Zhou qiuchu still slowly shook his head.

There is no doubt that Zhou qiuchu still disagrees with Chen Hui's approach.

Seeing the three people's eyes looking at themselves, Zhou qiuchu explained: "the method is feasible, but try not to use it. We put the meaning of crossing the Long Valley back here. In fact, we want to follow the vine and investigate the situation after crossing the Long Valley back. Therefore, any risky method should minimize the risk. If Liu Jie's method can work, Chen Hui's method can't be used. "

"This means that Liu Jie is the main one and Chen Hui is the auxiliary one." He Yanwei nodded and said: "it's just the separation of primary and secondary. Chen Hui's method should be included in the plan, because we are not sure whether the curator will go out when he makes an appointment with Watanabe Nagoya. So let's first plan the plan started by Liu Jie and list it as the first plan. If the first plan doesn't work, Chen Hui's method can be listed as the second plan, I think that's better! "

"He Ju is right." Zhou qiuchu nodded and said, "it's safe to make two action plans. Chen Hui's plan is listed as the second plan. Let's discuss Liu Jie's first plan one by one."

With these words, Zhou qiuchu looked at Liu Jie and asked, "first of all, we will solve the problem through the curator. The curator will ask Watanabe Nagoya to meet him outside. Do you have any suitable place?"

"Nanjiang Flower Valley!" Liu Jie gave an answer almost instantaneously, saying: "Huagu is an artificial scenic spot developed by us in Nanjing. It's suitable for a day's visit. It's basically our local people in Nanjiang. We spend more leisure time on weekends. It can be said that the flower sea and green plants echo each other. The passenger flow is good, but it won't be crowded. At the same time, being between the flower sea and green plants will make people very relaxed, When people relax, their vigilance will drop

"Well, the place is in the Flower Valley of Nanjiang." Zhou qiuchu nodded and said, "what other prerequisites need to be met?"

"I need someone to cover for me." Liu Jie said: "this kind of thing, to put it bluntly, is to attract Watanabe Nagoya's attention, let him not pay attention to his backpack!"

Hearing Liu Jie's words, Zhou qiuchu immediately asked: "generally speaking, those who do this kind of thing should go with you. Miss Liu, can't your people cover you?"

Liu Jie shook her head slowly and said, "it's not appropriate. If you just steal the tripod, you don't need any cover. If you want to change the bag, you must give me a certain amount of time. My people can't buy me time!"

After a pause, Liu Jie said: "I've been thinking about this problem just now, how to buy me time, but I haven't thought of a suitable way, because Watanabe Nagoya is a Japanese and has a certain vigilance. If you want to buy time, you have to talk to Watanabe Nagoya to attract his attention."

When Liu Jie said this, she looked helpless. Obviously, she didn't think of any way.

Zhou qiuchu pondered for a while, said: "I can try!"

Hearing Zhou qiuchu's words, Chen Hui's three eyes all looked at Zhou qiuchu.

Zhou qiuchu continued: "I can speak Japanese. I can pretend to be Japanese and communicate with Nagoya Watanabe in Japanese. I don't know how long it will take you, but I don't know."

Zhou qiuchu asked Liu Jie about this sentence. Liu Jie pondered for a moment and said, "three minutes is enough!"

Chen Hui said at this time: "there are many variables in the first plan. Because Watanabe Nagoya is a living person, I think we just need to plan the feasibility, and then we can adapt to the situation. Zhou qiuchu's method is feasible. It's normal to meet another native in Nanjiang and have a few conversations, I'm sure I can get three minutes! "

"Although Watanabe Nagoya can speak our Mandarin, he still has a strong taste of listening." Zhou qiuchu said with a smile: "you can borrow this point to start a conversation with him."

When Watanabe changgu had dinner with the curator, Zhou qiuchu monitored the whole process and knew what level of Watanabe changgu's Mandarin was.

"Then there's no problem." Liu Jie nodded, said: "about Watanabe Nagoya to Huagu, I first make sure that there is no tripod in his backpack, if there is, we will proceed according to the plan, if not, we can withdraw immediately."

Hearing Liu Jie's words, Zhou qiuchu nodded, turned to Chen Hui and asked, "now let's talk about the second plan. What can you do with the medicine you can make? What I've already said is how to use this medicine? Is it necessary to enter the abdomen, or by other means? "

"No need." Chen Hui said: "Watanabe Nagoya's hotel uses central air conditioning. You just need to open a hole in the air duct leading to Watanabe Nagoya, put the medicine in, the medicine volatilizes, and the air from the central air conditioning blows into the room. Moreover, if you open a hole in the air duct leading to Watanabe Nagoya, you can confirm whether he has turned on the air conditioning!"

"How long will it take?" Zhou qiuchu asked.

"Half an hour." Chen Hui said: "the efficacy should not be too strong, we must grasp the appropriate dosage, the duration of efficacy is about more than an hour, time is enough!"

Zhou qiuchu nodded, looked at Liu Jie, and said: "even if we adopt the second plan, we still need Liu Jie to implement it, because Watanabe Nagoya is likely to do some anti-theft measures in the hotel door before going to bed. If we open the door, it may destroy the security measures of Watanabe Nagoya, which will expose our feet."

"You can get in through the window." "It's not a problem for me," Liu said

"The two plans have been settled." Zhou qiuchu said at this time: "from tomorrow, we will make preparations separately. Let the curator invite Watanabe changgu to visit Huagu at the weekend. If we fail in Huagu, we will implement the second plan that night!"

After saying this, Zhou qiuchu looked at the time and said, "it's getting late. Let's have a rest. We must have a good rest these two days. We should keep our energy and adjust ourselves to the best condition."
