Chapter 192 Start the pot and burn the oil
East Palace, Chongxian Pavilion.
Today, a new nature class has been added, which is taught by the owner Qin Lang himself. In the eyes of all the straight scholars, this natural course is purely a miscellaneous course, teaching some messy things. However, it is loved by all the students in the Chongxian Hall. Even Li Tai, the little fat Wei Wang who has never been convinced by Qin Lang, can concentrate on listening every time he takes a nature class.
Today's nature class is a little different. Today is an open class. The so-called open class is also a concept introduced by Qin Lang, that is, each gentleman arranges an open class every ten days, and other direct bachelors also come to listen to the lectures, and sometimes even invite some parents of students to come to listen to the lectures.
Occasionally, if the prince and grand master are free, they will be invited to come.
Therefore, this kind of public class is very formal. After all, the parents of the students in Chongxian Hall are either prime ministers or princes.
Today not only the prince, six masters and four guests came, but even the emperor came in person.
In the main hall of Chongxian Hall, one hundred and eight students sat upright, each with a small desk.
On both sides are the emperor, prime minister, princes, and straight scholars.
Qin Lang set up a large blackboard in the hall, and wrote on it with white chalk. He drew with chalk on it, and Li Shimin and others were watching carefully, and no one bothered.
"Students, today we are going to talk about locusts in this nature class. There are many types of locusts. It is a kind of insect, and it is a kind of pest..."
After a simple opening, Qin Lang brought a container, which was a very transparent box, it could be seen that it was made of precious colored glaze, and the transparent colored glass box was filled with soil, and one side could clearly see the Many eggs.
"Students, this is a locust. There are three parts of a locust, which are egg, nymph and adult. The nymph stage is also called locust pupa. As they grow, they will shed their original exoskeleton. It is called molt, and it takes five molts in a lifetime to become an adult."
"Everyone, please look carefully at my soil box. Inside this box are locust eggs that have not yet hatched. These light yellow rice grains are locust eggs. They look very small, right? Don't underestimate them, the reproductive ability of locusts They are very powerful, and it takes at most thirty days from hatching to laying eggs. A female locust can lay more than 200 eggs, and at most more than 1,000 eggs."
"Have you seen any eggs in my glass box? It is about three inches from the soil surface. When the female locust lays eggs, a sharp oviposition tube protrudes directly from the tail and inserts it so deep into the soil to lay eggs directly. The ones that lay about 50 eggs at a time, these eggs are inactive in the soil, but can be stored for a long time. The eggs laid in summer are born in autumn, and the eggs laid in autumn can survive the winter until they are born in the next summer, so locust plagues often appear In the summer and fall..."
As he spoke, Qin Lang brought up another glass box, some of the locust eggs inside were already hatching.
"Which student is willing to come up and observe closely, and explain what he has observed to the students?" Qin Lang asked.
Suddenly, dozens of little hands raised up.
Qin Lang saw the little fat man Li Tai eager to try, so he called his name.
"I invite Li Tai to come up to observe and explain."
Li Tai stood up proudly and came to the podium.
He observed carefully around the glass box for a long time, then raised his head, looked at more than a hundred students below, and dozens of emperors, princes and prime ministers who were listening, and he couldn't help feeling a little nervous.
“Just tell what you observe.”
"Master, may I talk about the one that is shedding its skin first?" "Yes."
"Okay, everyone, here is a locust larva that is molting. Its body is pale white with a little light red when it emerges from the shell. It is covered with a temporary armor. It puts its tentacles and legs Tightly attached to the chest and stomach, it is moving forward, the paws are loosened a little, and the hind legs are kicked straight..."
Li Taiyue became more and more fluent, "It arches so hard, it seems to have a vesicle in its neck, which bulges and contracts regularly, and pushes obstacles tremblingly..."
"It finally tore the temporary coat, and flexibly pulled it back with its hind legs, and finally peeled off the skin with its hind legs."
"This guy seems to be free. Although the color looks very pale, looking at the current appearance, it has grown to another stage!"
·······
What Li Tai said is quite good. Although the angle is different, it is the perspective of children. It is rare for them to see the moulting process of a locust.
"Student Wei Wang observed very carefully just now. This locust larva has indeed entered a new stage. It has now evolved into a jumping gnat. It hasn't grown wings yet, and it can't fly yet, but it has With a pair of strong legs, it can jump very far, and it already knows how to eat. It eats everything it encounters, whether it is crops or weeds and leaves..."
Qin Lang took out several small boxes, each containing a specimen.
From the initial locust egg, to the five nymph stages of the jumping gnat, and finally to a mature locust.
Made amber with rosin for clarity.
"See, these locusts grow up again and again like this. Their growth period is very short, from hatching to laying eggs, up to 30 days, but in these 30 days, if enough locust swarms gather, they can destroy the sky." Destroy the land and cause a great famine for thousands of miles."
Li Shimin also listened to the questions below. He was under 30 years old. Before the age of 16, he was a son of the royal relatives and princes of the previous dynasty. I have never really known a locust.
Qin Lang's lecture was easy and thorough, and he quickly explained the short life of a locust.
"When the locusts are still in the eggs, they are in the soil, mostly on the banks of the river. At this time, digging the eggs is actually very hard, and the effect is not good. When the locusts reach the third stage of adulthood, they will grow wings and grow. Flying, so it is more difficult to catch, and it is also the period that causes the greatest harm. Summer and autumn are also the important time for crop production. The locusts pass by, and the grass does not stay. Therefore, we must fight against the locusts and try our best to eliminate them. .”
"Who can tell me when is the best time to eliminate locusts?"
"Let's ask the prince to answer."
Chengqian stood up, still a little shy, "We should kill the locusts while they are still in the nymph stage of moulting."
"The answer is very good. Please sit down, Prince. If you want to kill the locusts, kill them before their wings grow, and don't give them the chance to gather in groups and cause trouble."
Qin Lang explained the profound things in a simple way, and vividly told everyone about the various stages of locusts, the dangers of locusts, **** locusts, etc.
Finally, Qin Lang actually asked someone to bring over several stoves, spatulas, etc.
Even Li Shimin was stunned by this scene.
What does this mean?
The stove has already been fired, and the fire is booming, so put the pot directly on it.
"Now is our recess time, the teacher will show you another good way to deal with locusts, which is also a rare usefulness of locusts."
"Now start the pot and burn the oil!"
·······
Qin Lang was skillful in his movements. He picked up a net bag of locusts that had been soaked in water from a bucket, and poured them into a wooden basin.
The students all craned their necks to watch.
"Actually, in many places such as Lingnan and Southwest, the local people have a custom of eating insects. There is even a banquet of hundreds of insects. They can find ways to get them to eat. Locusts are actually a delicacy, they eat five grains and herbs, are non-toxic, suitable for frying, and taste like chicken."
"Take care of the caught locusts first. It is best to soak them in water for a few hours, and then you can tear off their hind legs and wings. These locusts are jumping gnats, and they haven't grown wings yet, so as long as Just tear off the hard, spiky hind legs, dry it out and put it in the water, then coat it in flour and fry it."
"Of course, if you want something more delicious, you can add an appropriate amount of salt and pepper to this flour. Today I will add a little bit of my exclusive secret thirteen incense."
When the locusts fell into the oil pan and made a sizzling sound, Li Shimin and others below finally believed that Qin Lang really wanted to fry the locusts, and to eat them.
60% of the oil temperature is fried for the first time, and the frying is almost done, then the oil is controlled, and then the oil is heated up and fried again.
After the second frying, those fat hoppers that have grown into adults are already golden and golden, especially after the surface is covered with flour, it is like a golden helmet.
Oil filter.
Sprinkle with some secret seasoning and put it on a plate.
Finally sprinkle a little green onion, and you're done.
Qin Lang picked up one directly, and threw it into his mouth, chewing, making a crunchy sound.
"The outside is charred and the inside is tender, crispy and delicious, delicious!"
Li Shimin was in a daze.
How can locusts be edible?
Is it delicious?
"Which classmate is willing to try the teacher's craft?"
Li Tai, who had been very active before, turned pale, and quickly avoided Qin Lang's eyes.
Chengqian also shook his head.
"Teacher, I want to try."
Class monitor Li Cunxiao stood up bravely. In fact, this kid had already beaten Qin Lang several times. Otherwise, Qin Lang would not be able to succeed once with such a good skill. Therefore, this guy has already experienced fear and doubt, and finally came to Zhenxiang the process of.
"Okay, please let our squad leader Li Cunxiao come and taste it, and then express your feelings."
Cunxiao stepped forward, picked up the locusts and started to eat them crunchily. After eating one, another one came immediately. After he ate three in a row, he finally remembered that it was in class.
He picked up another one, facing the students, "The teacher just said that this tastes like chicken, but it's not true."
After hearing this, there was a lot of voices below, wondering if this is right, how could locusts have the smell of chicken.
"This fried locust is much better than chicken!"
When Li Cunxiao said this, there was a lot of surprise.
