Ask Sword

The Turkic teenagers and girls in the audience applauded Jia Luo's victory loudly, while Dou Chi and the others looked unsightly, and Ashid Tumen was caught between the two groups of people, looking extremely embarrassed.

Next, Xue Che and other teachers selected more than a dozen groups of people to go up to practice, and Li Wei was also called to go up - relying on the advantages of height and arm length, he defeated the opponent.

And at the end of the class, Xue Che also announced a new rule - the large venue at the corner of the Martial Arts Field will be open to lower grade students in the near future,

There are several arenas in the venue, all of which are equipped with higher-level protective talismans.

It can defend the body from damage caused by weapons, mind power, and flying swords.

Academy disciples and foreign students can apply for the use of venues, and without worrying about getting injured, they can hone their martial arts skills for future competitions.

During this academic exchange, courses including Talisman Sword, Science, Military Science, Beasts, etc. will hold activities.

These activities will be staggered as much as possible, and when the official start, each participant will be awarded points based on performance.

As for the score evaluation system, it is said that Chao Wenyuan and other countries' mathematics doctors jointly formulated it through consultation.

To ensure both comprehensiveness and fairness,

It will not appear that someone participates in ten events, and the top ten every time,

As a result, he lost to another person who participated in 20 events and was in the top 100 every time.

After the physical education class was over, Li Wei and the others were still unsatisfied, and went to a large venue to continue making appointments.

Li Ang, who had no classes, went to the laboratory building first, got some things, and then returned to Jinchengfang mansion with Chai Chai.

————

Master, do you know that this academic exchange is not only between colleges and colleges, but even the chef industry has participated in it by the way.

Chai Chai took out stacks of vegetables from the lunch box, and said cheerfully: Those foreign missions may have brought chefs from their own country because they were afraid of being unaccustomed to the food of Yu country.

Results The personnel did not show the symptoms of acclimatization and inconsistency in diet.

So those foreign cooks simply exchanged their national cooking skills with the chefs in our school canteen. .

They even cook with rose petals, and they bring a shallot spice that, if you cut it with a knife and hold it some distance in front of your eyes, will make you cry involuntarily.

onion?

Li Ang thought for a while and said, and took out two small glass jars from his bag.

During the Han Dynasty, Zhang Qian went on a mission to the Western Regions, opened up the Silk Road, and brought back pomegranates, grapes, cucumbers, garlic and other crops.

Then, many kinds of plants were introduced to the Central Plains with the help of the land silk road and sea trade route.

Such as eggplant, lentils, mango and so on.

Onions are a good thing. I will go to the cafeteria one day to see if I can get some and make a plate of scrambled eggs with onions.

Huh?

Chai Chai saw cucumbers and white radish slices floating in the two jars, and asked curiously, This is water spinach?

Um.

Li Ang nodded. Spinach is kimchi, which refers to processed lactic-acid-fermented vegetables soaked in low-concentration salt solution. Because lactic acid fermentation can inhibit spoilage microorganisms, so that vegetables can be stored for a long time, it is very popular in the Central Plains and has a long history.

Li Ang's mother used to make bubbles a lot, and Chai Chai liked it very much. Now I have to prepare some at home every winter.

It's not ordinary kimchi, though.

Li Ang opened the jar, picked up two cucumber sticks with chopsticks, Try it.

Chai Chai opened his mouth and took it away, chewed for a while, with a puzzled look on his face, It feels...very crisp? How long did it take you to soak it, young master?

Less than half an hour.

Li Ang smiled slightly, I used a vacuum pump.

ha?

The circulating water vacuum pump is placed on the first floor of the laboratory building, and Chai Chai can see it every day, but how do you connect kimchi with the vacuum pump?

Common kimchi is to pickle vegetables with low-concentration salt water. During this process, lactic acid bacteria will grow, resulting in a decrease in pH value, limiting the reproduction of harmful bacteria, and even dying directly. This makes lactic acid bacteria dominant and continues to metabolize lactic acid continuously. So as to achieve anti-corrosion effect.

Li Ang said: However, in the early stage of fermentation, there are still Enterobacteriaceae bacteria and fungi. Their nitrate reductase will convert nitrate into nitrite.

Although nitrite is degraded later in fermentation, there is still a peak in nitrite levels during this process. If pickled improperly, or eaten early, it is harmful to the human body.

It could be poisonous, or increase the risk of cancer or something.

cancer?

Chai Chai tilted his head.

A disease that cannot be cured at this stage.

Li Ang said casually, As for the kimchi now, I actually just threw the cucumber sticks and white radish sticks into an open container, poured the salt water used for kimchi,

Then put the container into the vacuum chamber made of glass, and use the circulating water vacuum pump to evacuate the vacuum chamber.

In this way, the air in the cucumber strips will flow out along the small holes on the surface, allowing the pickle salt water to penetrate directly, replacing the air and water that the cucumber originally had.

It only takes a few minutes to achieve a penetration effect of several days or even a week, and it has a taste similar to that of traditional pickling, and the taste is also more crisp.

And don't worry about nitrite.

Li Ang tapped the glass jar with his chopsticks, I'll do some more research to see how to make the vegetables so soft and rotten. If it works, let's eat this this winter.

oh.

Chai Chai nodded with half understanding, his face blushed inexplicably.

Winter is coming, did Li Ang come up with this technology specially because he was afraid that she would eat water spinach?

Not to mention Chai Chai's little touch, Li Ang used his thoughts to take out the dishes from the lunch box and set the table and chopsticks.

The two of them finished their dinner and washed the dishes with their thoughts.

Chai Chai was doing homework in the study, while Li Ang was in the living room, studying a large piece of pork.

Qiu Feng's words echoed in his mind, he guided the thoughts into the body, used the power of thoughts to check the situation in the human body, and achieved the effect of an endoscope or even a tomographic scan

The development of medicine has always been Li Ang's ideal. If this path works, it can greatly promote the development of medicine in Yu State.

You must know that in another world, X-rays were discovered by German physicist Wilhelm Roentgen in 1895. The world's first X-ray film was also taken by him in December of the same year for his wife.

CT technology appeared in 1967,

In 1982, magnetic resonance medical imaging technology was officially used clinically.

In 1983, the electronic endoscope appeared,

If it develops step by step, God knows when Yu Guo will have similar technology to see the diseased organs under the skin without damaging the patient's skin.

[Psychic imaging] technology can be said to be the super acceleration of medicine, and it must be realized no matter what.
