Chapter 254 Reply
In the middle of the night, Li Ang sat at the table, flipping through the letters sent by his relatives and friends in Chang'an, his face faintly visible in the candlelight.
The long-distance communication ability of the chinchilla is limited to the number of times per month.
The younger the chinchilla, the fewer times it can be used each month. Therefore, even if it is a local governor, he can't use it for private purposes if he has no important affairs. He can "call" his relatives and friends in Chang'an.
More, contact by letter.
The school has ended its winter vacation, and the school has officially started. Academic exchange activities have also entered a new stage.
The agronomy competition is divided into many items, including flower group, fruit group, vegetable group, potted landscape group and so on.
Doctors of agronomy pay more attention to fruit and vegetable projects, to see if there are new crop varieties or new farm tools,
Students and the general public are more keen to appreciate rare flowers and potted landscapes, such as peonies, roses, orchids and so on.
At the scene of the competition, a white peony plant cultivated by the seniors of the academy even sold for 8,000 peonies.
In addition, there are math competitions.
The questions compiled by Ph.D. students from different countries gathered together, and many students complained incessantly.
The first place in the final arithmetic competition was won by a student from Xijing who was weak in writing and not like Jing people.
When the other party was still presenting the award, they sneered a few words intentionally or unintentionally, to the effect that indulging in the glory of the past would only make it impossible to make progress now and so on.
This makes the students of Yu State who have always boasted that they are excellent in mathematics very unhappy.
Yang Yu said in the letter that if Li Ang was still in the academy, the first place would definitely be Yu Guo.
He also asked for a blank test paper from Zhao Wenyuan, a Ph.
Wait for Li Ang to come back and do the exam questions by himself. When the time comes, give that Xijing mathematics student a good slap in the face.
"What is this? 'It's a pity that my generals Yan Liang and Wen Chou have not arrived. If there is only one person here, why be afraid of Hua Xiong'?"
Li Ang couldn't help but smile bitterly, and flipped through other letters.
In the letter from Aunt Song and Song Shaoyuan, Li Ang was asked to keep warm and not to be frozen by the cold spring.
In Li Leling's letter, she talked about trivial daily routines, such as the wedding that the palace prepared for her fourth brother Li Hui, which can be called unprecedented grand.
Emperor Yu and his wife really doted on this son the most. They not only used the money from the royal treasury, but also used a huge amount of wealth that cannot be explained in detail.
It made the other princes and princesses extremely envious and jealous in private.
"It seems that the rumors in Chang'an are indeed true. Those big merchants who show their faces in the eastern and western cities, such as Jin Wusuan, are more or less agents of the royal family in private business."
Li Ang shook his head, almost all the emperors of the Yu Kingdom did not like luxury and extravagance, and all of them had small golden caves, which is also a common problem of the royal family surnamed Li.
Cheng Juxiu, who was far away in Dengzhou, also heard the news that Li Ang went to Suzhou to contain the water poisoning epidemic, so he wrote a letter to encourage him.
also talked about the human-powered plane that took off in Dengzhou before.
smiled and said that one day Li Ang can develop a manned aircraft that can fly at high speed. At that time, it will only take one day to travel from the northern part of Yu State to the southern border of Yu State.
"Looking at the progress of Tantai Leshan and Dr. Su Feng, they might actually manufacture a manned aircraft before cars. Yu Guo's technology tree is really crooked."
Li Ang shook his head and smiled wryly: "At that time, we may have to set up an air traffic control bureau under the control of the six ministries to manage the airspace—there is a wind layer in the high sky, and monks have to report to the air traffic control bureau before using the flying sword to avoid hitting the plane head-on. .”
As Li Ang's status in the academy got higher and he read more banned books, he also felt more and more that there was a huge difference between the technology trees in the memory of Yu Kingdom and the foreign world.
Iron melting and iron casting, equivalent to CNC machine tools, industrial master machines,
Praying rain symbols are equivalent to artificial rainfall shells,
Burrow is equivalent to a shield machine.
In the memory of the alien world, those products that require countless pre-scientific technologies to be clicked out,
Even in some occasions, the effect of the spell talisman is even better.
More importantly, Alienation.
Li Ang's face was a bit serious, he actually lied to Qiu Feng during the day,
In his communication with Chang'an's close worm, the head of the mountain revealed that the academy secretly conducted a series of experiments,
Some alienated substances in Dongjun Tower can kill snails and schistosomes.
are just those alienated substances, without exception, have side effects.
For example, a thumb-sized fish that is harmless to humans and animals, called the double-guard fish, has the ability to divide itself. One life makes two, and two make four. It likes to eat small insects floating in the water, including the cercariae of schistosomes.
However, the division rate of this fish depends on the water system in which it is located.
The larger the water system, the faster the division.
If it is put into Taihu Lake, where the water network is dense, all rice fields will be filled with this small fish in a few years.
Not to mention that it may swim along the lake and into the sea.
There is also a gray-and-white animal shaped like an anteater and the size of a dog called the worm tongue.
The main food of the creep tongue is all kinds of snails.
It uses its slender tongue to pull out snails from the grass soil and eat them directly. The efficiency of a day is a thousand times that of humans, and it will not be infected by schistosomes.
The downside is that the excrement of the Wolverine is atomized, and it will form a highly toxic corrosive cloud when it comes into contact with the air.
Not only is it harmful to people, but it also penetrates into the soil, causing irreversible degradation of land fertility.
The heterogeneity of Dongjun Building is like a double-edged sword.
It is difficult to find a dissimilation substance that can exert its effect and has no side effects at all.
“It is always easier to destroy than to build.”
Li Ang sighed, and opened Chai Chai's letter.
Chai Chai wrote some trivial things in the letter, such as how difficult the exam is, there are a lot of homework, when will you come back, young master, etc.
At the end of the letter, Chai Chai had to add a sentence, the words above were all written by himself using his mind to control the paper and pen, isn’t it amazing.
Li Ang could even see the corner of her mouth curled up, complacent, waiting for praise.
"I should praise her well when I go back."
Li Ang put down the letter with a smile, picked up the brush on the pen holder, and prepared to reply.
However, the tip of the pen hovered on the paper for a long time, and I still didn't know what to write.
The dense and shocking flood of snails outside the city of Suzhou,
Countless families who have experienced life and death in the ward,
The bustling port no longer,
Taihu Lake full of plague water.
Li Ang hesitated again and again, and finally wrote a sentence like "Everything is fine, don't worry about it" in as relaxed a tone as possible, and put the letter paper into the envelope.
Waiting for tomorrow, and entrusting someone to send it to Chang'an.
After writing the reply letter, Li Ang finished washing and lay on the bed, but couldn't fall asleep after tossing and turning.
Simply, go and see Taihu Lake.
Li Ang opened his eyes and awakened the clone of Mosi hidden outside Suzhou City and deep underground.
