The handsome Gao Han stood up, saluted Wei Hong, and said slowly: "According to the Liuzhou Thorn History Letter, we have a preliminary understanding of the details of the rat infestation in Liuzhou. This year, Liuzhou has a bumper grain harvest, and as soon as there is more grain, there will be more rats, but the number of weasels and snakes, the natural enemies of rats, has decreased sharply. Without the containment of weasels and snakes, the rat population would not be controlled, and it would accumulate into harm. ”

From Gao Han's account, it can be known that the cause of the outbreak of rat infestation in Liuzhou is the destruction of the food chain, the lack of natural predators of rats, and the number of rats has increased dramatically. Usually a rat can steal a load of food in one night if it is left alone, if it is infested in groups, the amount of food stolen in one night is staggering, even if it is not stolen, it is destroyed by the rats unscrupulously, and the contaminated food can no longer be eaten. In addition, this year's grain harvest in Liuzhou, with abundant food, the breeding speed of mice will be greatly improved, and eventually the number of mice will be like a snowball, rolling bigger and bigger, causing greater harm. Although the loss of food is regrettable, it is not the biggest problem, and with the increase in the number of rats, in case of an outbreak of plague, it will be a devastating blow to the territory of Liuzhou. It is precisely because of the potential hazard of the plague that the Holy Lord attaches so much importance to it, and orders the prince of the country to give advice.

Theoretically, the safest and most effective way to exterminate rats is to use one thing in the biological chain to drop one thing, since Liuzhou lacks natural enemies of rats, then introduce some from other places. However, given the current situation, this approach is too slow to work and is not preferred. In order to curb the rat population in the short term and protect the food security as much as possible, it is necessary to think of an immediate solution.

After a simple thought, Wei Hong came up with a plan and said in front of everyone: "There are three ways to solve the rat infestation in Liuzhou. The first method is to buy a large number of natural enemies of rats such as weasels and snakes from other places to curb the number of rats in Liuzhou. This method is safe and practical, and it can also make up for the shortcomings of the biological chain in Liuzhou. However, the shortcomings are also obvious, the effect is slow, and after the rodent infestation is contained, a large number of weasels and snakes will pose a threat to humans and animals in a short period of time, and it takes a long time to integrate into the perfect biological chain system in order to completely eliminate the worries of Liuzhou, which is really the next policy. The second method is to attract some rats first, select the strong ones from them, and stuff them into the anus with soybeans. Because soybeans swell when exposed to water, rats cannot excrete, and will be slowly driven crazy to bite other similar people. But this method is more risky, after all, no one can guarantee that the rat will not bite after it goes crazy, although the effect is fast, the hidden danger is not small. As for the third method, it is to dig a pit first, then lure the rats into the pit, and when there are enough of them, they will cover it, add lime, and add water. When lime heats up in water, it will scald rats to death. Moreover, lime itself has the effect of killing viruses and sterilization, which avoids improper disposal of mouse carcasses and causes large-scale infectious diseases such as plague. This method is effective quickly, and can curb the number of rats in the short term, but it is not a long-term plan, so it needs to cooperate with the first method, in addition to killing rats in the pit, but also to introduce some natural enemies of rats from other places. The combination of these two strategies is really the best policy. ”

After listening to Wei Hong's words, the students discussed with each other, among which Gao Han asked: "The method that Wei Gongzi said is indeed very practical and has quick results. But Gao didn't understand something, and asked Wei Gongzi to answer. Previously, Wei Gongzi mentioned that rats were lured into the pit, how to solve this lure method? ”

Since Wei Hong can say this strategy, he naturally has a strategy: "There are many ways to lure mice, and the most effective method is to dry the crab shell and mix it with raw lacquer. Burn with fire. After mixing the two, it will release some special fragrances when exposed to fire, which has a fatal attraction to mice, and the fragrance released is also highly toxic, and has the effect of paralyzing nerves on insects and rats. ”

As soon as Gao Han sat down, another person got up and asked, "Young Master Wei, are you sure that your method will work?" ”

Wei Hong nodded noncommittally: "This is natural, but I am afraid that some of the details are not well mastered by others, and Wei needs to be taught in person." ”

Kong Yingda thinks Wei Hong's strategy is good and worth a try. But as Wei Hong said, people who have never done this kind of thing will really not be able to figure out the doorway for a while, and they must have Wei Hong himself to go into battle. Kong Yingda glanced at Li Xuanqing, asked Li Xuanqing to be by his side, and under Wei Hong's gaze, he covered his mouth and said a few words to Li Xuanqing. Immediately, Li Xuanqing nodded and said: "Everything is up to Mr., Wei Hong came to the capital this time for the rat infestation in Liuzhou, what is the dispatch of Mr., just tell him." ”

For himself, a well-behaved and sensible student, Kong Yingda is very satisfied. Looking at each other and smiling at Li Xuanqing, Kong Yingda turned to look at Wei Hongyan and said, "Master Wei, you said that you must personally participate in this matter, and the old man feels the same." In order to solve the rat infestation in Liuzhou as soon as possible, the old man should not delay, and immediately prepare a letter to the Holy Lord, and send you to Liuzhou to solve the matter. ”

Although Wei Hong had long been ready to go to Liuzhou, when he saw Li Xuanqing and Kong Yingda's eyebrows, he always felt as if he had been sold. The drum beat in his heart, but now there is no way back, Wei Hong can only face the difficulties: "Listen to the dispatch of the Lord of the Sacrificial Wine." ”

As soon as Wei Hong agreed, the matter was settled, and Kong Yingda immediately drafted a book. And Wei Hong left Guozi Academy under the leadership of Li Xuanqing, and without going out a few steps, Du He caught up, circled around Li Xuanqing, and ignored Wei Hong next to him: "Xuanqing, will there be time later?" Can you have a face? ”

Li Xuanqing's attitude towards Du He is similar to that towards Fang Zhizhi, lukewarm: "Unfortunately, Xuanqing has just returned to the capital, and there are still many things to deal with, so it's better to change it." After that, he ignored Duhe.

The hot face was attached to the cold buttocks, Du He was a little embarrassed, and when he saw Wei Hong snickering beside him, he suddenly became angry. The strategy given by Wei Hong just now, Du He listened to it, although the Guozijian unanimously approved it, but Du He was a little ignorant. In his opinion, Wei Hong's strategy is completely sideways, unusable, and just a little clever. I really don't know what is going on with Li Xuanqing, I don't want to let go of a handsome boy like myself, but I am so close to people like Wei Hong who like to play smart. As soon as he thought of this, Du He became angry, if he can't get Li Xuanqing, don't think about it! was ready to embarrass Wei Hong right away.;
