Both methods proposed in succession were denied. Yi Zhizuo was embarrassed without any sense of embarrassment. He calmly picked up the teacup and drank tea. Wu Changqing glanced at him, secretly making funny and said the big words, but none of them were useful. This guy still looked like an old god.

Wu Bingjian said with anticipation: "Don't hide it, what else can I say it out loud? Assam tea has a great deal. I will do my best to do whatever I can."

There is still a way to not be said? Wu Changqing was a little surprised and curious. In addition to sending people to Assam to destroy, there are other ways to destroy Assam’s tea garden?

Yi Zhizu put down the teacup and said, "I heard foreign sailors tell you in Huangpu that when I was sailing in the sea, I encountered a strange thing. There was an island on their route. A few years ago, they landed on the island and never saw a mouse. This time, I passed by the island, but I found that the rats on the island were in disaster. Except for the mice, there were no other living creatures on the island..."

Seeing him suddenly talking about his experiences at sea, Wu Changqing couldn't help but be stunned. Can this guy speak more normally? How can he destroy Assam's tea garden? Why did he get involved in the experiences at sea that were unrelated to? Is this related to the destruction of Assam's tea garden? Is it related?

"... I thought about it later that there should be no mice on the island. Occasionally, mice slipped onto the island from merchant ships. There were no natural enemies of mice on the island, such as cats, snakes, owls, foxes, etc., so mice quickly flooded and devoured all the animals on the island...."

Wu Changqing said with some dissatisfaction: "Can the mouse swallow all the living creatures on the island?"

"Of course there will be no large animals on the island, such as tigers and leopards." Yi Zhizu smiled and said, "In fact, even if there are tigers and leopards, they will be extinct by rats. It's very simple. If the mice are in disaster, they will eat everything they can eat. Tigers and leopards do not have enough food. Extinction is a matter of time."

"Oh." Wu Changqing said lightly, looking disapproving, but was wondering in his heart if this matter had anything to do with destroying the Assam Tea Garden?

Yi Zhizu ignored him and then said, "I am very curious about this phenomenon. I have thought about it and gave this phenomenon a name called invasion of foreign species. I thought that no matter east, west, south, or in general, as long as the place is full of vitality, the place will be in a state of balance, called ecological balance. Once the ecological balance is broken, it will suffer a catastrophe.

Take the grassland as an example. In order to curb the growth of Mongolia, we have racked our brains, married marriage, trade, and war, but the results have been very little. In fact, the younger generation thinks that there is no need to be such trouble. We just need to buy wolf-skinned wolf-skinned skins, fox-skinned fox-skinned fox-skinned and eagle-skinned cubs at high prices, and we can destroy Mongolian tribes in a few years."

This became more and more outrageous. Wu Changqing couldn't help but say, "That's so simple?"

"It is the case in theory." Yi Zhizu said with a solemn expression: "The animals that are most harmful to the grassland are rabbits and mice, because rabbits and mice not only eat grass, but also make holes. One is to damage the grass roots, and the other is to mound the soil dug out on the ground, which will crush the grass.

The natural enemies of rabbits and rats are foxes, wolves and eagles. If these three natural enemies are eliminated, rabbits and rats can reproduce quickly and become disasters. In this way, within a few years, the grassland will be destroyed and then desertified. Without the grassland, can the Mongolians survive?"

After hearing this, Wu Changqing finally reacted and said, "Brother Yi is going to use foreign invasion to destroy the Assam tea garden?"

"It is an invasion of foreign species." Yi Zhizu corrected the way.

Wu Bingjian said with a serious expression: "Assam is not a small island or a grassland, but a river valley. Besides, tea trees are not as fragile as grass."

Yixiu said with confidence: "The younger generation believes that the ecological balance of grasslands, plateaus, plains, mountains, hills, rivers, valleys, and swamps has been formed through long-term evolution. Species in this equilibrium have been through hundreds of years of competition, exclusion, adaptation and mutual benefit and mutual assistance, and finally form a equilibrium state of mutual dependence and mutual restraint.

Once you are invaded by foreign species or artificially destroy any link, you can break the original ecological balance and cause an unimaginable catastrophe."

After a short meal, he continued: "I don't know whether tea trees are delicate or not, but tea trees must have high requirements for the growth environment and climate. Otherwise, British colonies would be spread all over the world, and wild tea trees would not only be found in India and Ceylon."

Speaking of this, his tone changed, "Of course, these are just theoretical inferences and have never been practiced. However, my younger generations believe that destroying tea gardens by manpower is just a temporary solution. If we can destroy them, the British can also plant them, so that they can only treat the symptoms but not the root cause.

If you want to treat both the symptoms and the root causes, once and for all, and to monopolize the tea trade for a long time, invasion of foreign species is the only way to do it. Once this method is mature, even if the British open tea gardens in the British Isles, we can destroy it without any effort.

Also, this method is not only limited to tea trees. The mulberry trees necessary for raising silkworms can also be destroyed through this method, and even food crops can be destroyed!”

Wu Bingjian, who had never had any changes in his expression, was moved by this and asked in a hoarse voice: "Take it serious?"

Yi Zhizu nodded and said, "It is indeed possible, but this takes time. It requires long-term research and professional talents. It is not something that can be achieved overnight. The younger generation of Jianyixue plans to cultivate professional talents in plants, insects and animals."

“How long will it take?”

After hesitating, Yi Zhizu said: "Even if there is sufficient funds, it will probably take seven or eight years. Assam and Ceylon are all from Asia. Effective alien species are probably to find from America, Africa, and Europe. The most difficult thing is to cultivate professional talents..."

"There is no faster way?" Wu Bingjian frowned and said in a deep voice: "Assam's tea garden has been successfully opened, and the British can produce tea on a large scale in four or five years."

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

"This method can be tried." Wu Bingjian said with a slight hue: "It should cause a lot of trouble and losses to the British." His fingers knocked on the chair for a while, and he continued: "Jianyixue, how much money do you need?"

Finally, when he took the initiative to speak, Yi Zhizu breathed a sigh of relief and said, "The junior charity school is actually a new school. In addition to Chinese, it also prepares a series of courses such as foreign languages, mathematics, handicrafts, physics, chemistry, astronomy, geography, plants, animals, etc., aiming to cultivate professional talents in various fields.

Among them, foreign languages, astronomy, geography, plants, animals and other courses are closely related to foreign species invasion and ecological balance. To form a scale, the expenses are probably a bit large..."
