Late at night, Li Ang sat at the table, flipping through the letters sent by relatives and friends in Chang'an, his face looming in the candlelight.
The remote communication ability of the close insect is limited to the number of times per month.
The younger the proximate insect, the fewer times it can be used each month. Therefore, even a local governor cannot use it for public or private purposes and make "phone calls" to relatives and friends in Chang'an without important matters.
More often, we communicate through letters.
The winter vacation in the Academy has ended and the semester has officially started. Academic exchange activities have also entered a new stage.
The agronomy competition is divided into several categories, including flower group, fruit group, vegetable group, potted landscape group, etc.
Agricultural doctors pay more attention to fruit and vegetable projects to see if there are any new crop varieties or new agricultural tools.
Students and the general public are more interested in admiring rare flowers and potted landscapes, such as peonies, roses, orchids, etc.
At the competition site, a white peony cultivated by the academy senior even sold for 8,000 guan.
In addition, there are arithmetic competitions.
Doctors in mathematics from different countries came together to compile questions that made many students complain incessantly.
In the end, the first place in the arithmetic competition was won by a West Jing student who was not as elegant as a Jing native. .
While the other party was still presenting the award, he made some mocking remarks intentionally or unintentionally, to the effect that dwelling on past glory would only make it impossible to make progress in the present.
This made the students of Yu State, who always prided themselves on being excellent in arithmetic, particularly unhappy.
Yang Yu said in the letter that if Li Ang was still in the academy, the first place would definitely be from Yu State.
He also asked Chao Wenyuan, a Ph.D. in mathematics, for a blank test paper. He originally planned to put it in an envelope and send it over, but then he thought it might disturb Li Ang, so he decided not to send it out yet.
Wait for Li Ang to come back and do the test questions yourself. When the time comes, give that Xi Jing math student a good slap in the face.
"What does this mean? 'It's a pity that my generals Yan Liang and Wen Chou have not arrived yet. If you are alone here, why should you be afraid of Hua Xiong'?"
Li Ang couldn't help but smile, and started to read 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 late spring cold.
In Li Leling's letter, she talked about some trivial daily matters, such as the wedding prepared by the palace for her fourth brother Li Hui, which was unprecedentedly grand.
Emperor Yu and his wife really doted on this son the most. They not only used money from the royal treasury, but also used a huge fortune whose origin cannot be explained in detail.
This made the other princes and princesses secretly extremely envious and jealous.
"It seems that the rumors in Chang'an are indeed true. Those big businessmen who are prominent in the east and west 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. They all had small golden caves. This was a common problem among the royal family surnamed Li.
Cheng Juxiu, who was far away in Dengzhou, also heard the news that Li Ang went to Suzhou to curb the water poisoning epidemic, and wrote a letter to encourage him.
He also talked about the human-powered aircraft that took off in Dengzhou before.
He smiled and said that he looked forward to the day when Li Ang could develop a manned aircraft that could fly at high speed. By then, it would only take one day to travel from the northern part of Yu State to the southern part of Yu State, and he could bring his family with him. Wouldn't it be wonderful?
"Judging from the progress of Dr. Tantai Leshan and Dr. Su Feng, they might really be able to build a manned aircraft before cars. The technology tree of Yu State is really crooked."
Li Ang shook his head and smiled bitterly: "At that time, we may have to set up an air traffic control bureau under the jurisdiction of the Sixth Department to manage the airspace - there is a strong wind layer high in the sky. The monks must report to the air traffic control bureau before using the flying sword to avoid a head-on collision. airplane..."
As Li Ang's status in the academy grew higher and the more banned books he read, he felt more and more that there was a huge difference between the technology trees in the Yu Kingdom and the memory of the other world.
Iron melting and iron casting are equivalent to CNC machine tools and industrial machines.
Rain prayer charms are equivalent to artificial rainfall cannonballs.
Burrowing is equivalent to a shield machine...
In the memory of another world, those products that require countless prerequisite science and technology can be clicked.
In this world, it can be completely replaced by spiritual power and magical talismans.
Even on some occasions, the effects of spells and talismans are even better.
More importantly, alienated objects.
Li Ang's face was a little solemn. He actually lied to Qiu Feng during the day.
In his close communication with Chang'an, the mountain leader revealed that the academy secretly conducted a series of experiments.
Certain alienated substances in Dongjun Tower can kill snails and schistosomiasis.
It's just that those alienated substances have side effects without exception.
For example, a fish about the size of a thumb, harmless to humans and animals, is called the dichotomy. It has the ability to divide itself, giving birth to two and two to four. It likes to eat small insects floating in the water, including cercariae of schistosomiasis.
However, the rate at which this fish divides depends on the water system in which it lives.
The larger the water system, the faster it will split.
If released into Taihu Lake, which has a dense water network, all the rice fields will be occupied by this small fish within a few years.
Not to mention that it might swim along the lake and into the sea.
There is also a gray-white animal that looks like an anteater and is as big as a dog, called the worm.
The main food of the worm is all kinds of snails.
It uses its long and slender tongue to dig out snails from the grass and soil and eat them directly. Its efficiency is a thousand times that of humans in a day, and it will not be infected by schistosomiasis.
The disadvantage is that the worm's excrement has atomizing properties, and when exposed to the air, it will form a highly toxic corrosive cloud.
It is not only harmful to people, but also penetrates deep into the soil, causing irreversible degradation of soil fertility.
The aliens in Dongjun Tower are like a double-edged sword.
It's hard to find a drug that works without any side effects.
"It is always easier to destroy than to build."
Li Ang sighed and opened Chai Chai's letter.
Chai Chai said some trivial things in the letter, such as how difficult the exam is, how much homework there is, when will you come back, young master, etc.
At the end of the letter, Chai Chai had to add that the words above were all written by himself using his mind to control the pen and paper. Isn't that amazing?
Li Ang could even see the corners of her mouth curled up, her expression filled with pride, waiting for praise.
"It's time to praise her when we get back."
Li Ang smiled and put down the letter, picked up the brush on the pen holder, and prepared to reply.
However, the pen hovered on the paper for a long time, and I still didn't know what to write.
The dense and shocking proliferation of snails outside Suzhou City,
Countless families in the ward have experienced life, separation, and death.
A port that is no longer prosperous,
Taihu Lake flooded with epidemic water...
Li Ang hesitated again and again, and finally wrote something like "Everything is fine, no need to worry" in as relaxed a tone as possible, and put the letter paper into the envelope.
Waiting for tomorrow, I will ask someone to send it to Chang'an.
After writing the reply, Li Ang finished washing and lay on the bed, but he tossed and turned and couldn't fall asleep.
Simply, go see Taihu Lake.
Li Ang opened his eyes and awakened the clone of Mosi hidden deep underground outside Suzhou City.
