The two methods proposed in a row were denied, Yi Zhishu was not embarrassed at all, and picked up the teacup and drank tea with a calm expression, Wu Changqing glanced at him, secretly amused, the big words came out, but none of the methods were useful, this guy still looked like an old god.

Wu Bingjian said expectantly: "Don't hide it, if there is any way to say it and listen to it, Assam tea is very important, but if you can, the old man will do his best." ”

Is there a way I haven't said it? Wu Changqing was a little surprised and a little curious, in addition to sending people to Assamese to destroy, there were other ways to destroy Assam's tea plantation?

Yi Zhizu put down the teacup and said: "The younger generation in Huangpu once heard the foreigner sailor say that when sailing in the sea, he encountered a strange thing, there was a small island on their route, they landed on the island a few years ago, they had not seen a mouse, this time through the island, but found that the island was plagued by rats, and there were no other living creatures on ......the island except rats. ”

Seeing that he suddenly talked about what he had seen and heard at sea, Wu Changqing couldn't help but be a little stunned, can't this guy speak normally? How did this good talk about how to destroy the tea plantations of Assam, and how did he get involved in the sea that the wind and horses and cattle are not related? Does this have anything to do with the destruction of Assam's tea plantations? Does it matter?

“…… The younger generation pondered afterwards that the island should have been free of rats, and occasionally rats slipped onto the island from merchant ships, and there were no natural enemies of rats on the island, such as cats, snakes, owls, foxes, etc., so the rats quickly flooded and devoured all the original animal ...... on the island. ”

Wu Changqing said with some dissatisfaction: "Rats can devour all the living creatures on the island? ”

"Naturally, there are no big animals on the island, such as tigers and leopards." Yi Zhicontent said with a smile: "In fact, there are tigers and leopards and the like, and they will also be exterminated by rats, very simply, rats are plagued and will eat everything they can eat, tigers and leopards do not have enough food, and extinction is a matter of time." ”

"Oh." Wu Changqing sighed lightly, his face was disapproving, but he was thinking in his heart What does this matter have to do with the destruction of the Assam Tea Garden?

Yi Zhicontent ignored him, and continued: "The younger generation is very curious about this phenomenon, and they have tried their best to think about it, and they have given this phenomenon a name, which is called invasive alien species. The younger generation thinks that no matter the east, west, north and south, as long as the place is vibrant, the place is in a state of equilibrium, called ecological balance, and once the ecological balance is broken, it will suffer from extinction.

Take the steppe as an example, in order to curb the growth of Mongolia, the successive dynasties can be said to rack their brains, and relatives, trade, and war, but with little effect, in fact, the younger generation thinks that there is no need to be so troublesome, only need to buy wolf skin wolf cub skin and fox skin fox cub skin and eagle cub at a high price, and it will not take a few years to wipe out the Mongolian tribes. ”

The more he said this, the more outrageous it became, Wu Changqing couldn't help but say, "It's so simple? ”

"In theory, so." Yi Zhicontent said with a solemn expression: "The animals that are most harmful to the grassland are rabbits and mice, because rabbits and rats not only eat grass, but also burrow, one of which damages the grass roots, and the other is that the soil dug out of the hole will crush the grass in the ground.

The natural enemies of rabbits and mice are foxes, wolves and eagles, and if these three natural enemies are eliminated, rabbits and mice will be able to reproduce quickly and become flooded, so that in a few years, the grassland will be destroyed, and then desertification, without the grassland, the Mongolian people can still survive? ”

Hearing this, Wu Changqing finally reacted and said, "Brother Yi is going to use foreign... How to destroy the Assam tea plantation? ”

"It's an invasive alien species." Yi Zhicontent corrected.

Wu Bingjian said with a solemn expression: "Assam is not an island or a grassland, but a river valley, and besides, the tea tree is not as fragile as pasture. ”

Yi Zhi said with certainty: "The younger generation believes that the ecological balance of grasslands, plateaus, plains, mountains, hills, river valleys, and swamps is formed through long-term evolution, and the species in this equilibrium state have been through hundreds of thousands of years of competition, exclusion, adaptation, and mutual benefit, and finally formed a balanced state of interdependence and mutual constraint.

Once it is invaded by alien species, or any link is artificially destroyed, it can break the original ecological balance and cause unimaginable catastrophe. ”

After a pause, he continued: "Whether the tea tree is delicate or not, the younger generation is not very clear, but the tea tree must have high requirements for the growing environment and climate, otherwise the British colonies are all over the world, and wild tea trees will not be found only in India and Ceylon." ”

Speaking of this, his tone changed, "Of course, these are only theoretical inferences, and they have never been practiced, but the younger generation believes that manpower to destroy the tea garden is just an expedient measure, we can destroy it, and the British can also plant it, so it can only treat the symptoms but not the root cause."

If you want to cure both the symptoms and the root causes, once and for all, if you want to monopolize the tea trade for a long time, the invasion of alien species is the only feasible way, once this method is mature, even if the British open up tea plantations in the British Isles on the British mainland, we can destroy it without much effort.

Moreover, this method is not only limited to tea trees, but also mulberry trees, which are necessary for raising silkworms, can also be destroyed through this method, and even food crops can also be destroyed! ”

Hearing this, Wu Bingjian, who had never been in the gujing and rarely changed his expression, was also moved, and asked in a hoarse voice: "Really?" ”

Yi Zhizhi nodded and said: "It is indeed possible, but it takes time, it requires both long-term research and professional talents, it is not an overnight thing, and the younger generation plans to cultivate professionals in plants, insects, and animals." ”

"How long will it take?"

After hesitating, Yi Zhizhi said: "Even if there are abundant funds, I am afraid it will take seven or eight years, Assam and Ceylon are both Asian, effective alien species, I am afraid that we have to find them from the Americas, Africa, and Europe, and the most difficult thing is the training ...... professional talents." ”

"There's no faster way?" Wu Bingjian frowned, and said in a deep voice: "The tea plantation in Assam has been successfully developed, and the British will be able to produce tea on a large scale in four or five years. ”

After a moment of silence, Yi Zhizhi said, "Can you find someone to collect the common and rare pests and diseases of Fujian tea trees and send them to Assam?" ”

"You can try this." Wu Bingjian bowed slightly: "It should be able to cause a lot of trouble and losses to the British." Tapping his fingers on the chair for a while, he continued, "Jianyixue, how much silver do you need?" ”

Finally waited for him to take the initiative to speak, Yi Zhifen secretly breathed a sigh of relief, and said: "In addition to the Chinese language, it also prepares a series of courses such as foreign languages, mathematics, handicrafts, physics, chemistry, astronomy, geography, plants, and animals, aiming to cultivate professionals in various fields.

Among them, foreign languages, astronomy, geography, plants, animals and other courses are closely related to the invasion of alien species and ecological balance. ”

This is the most obvious bundle, bundling righteousness with the invasion of alien species and ecological balance, although Wu Bingjian saw through his little trick at a glance, he didn't care at all, and asked without hesitation: "How much do you estimate?" ”
