Chapter 059

On the other hand, the reality could no longer tolerate Huang Zhong and Zhang Ji deserting. The red-eyed Southern Huns, regardless of casualties, set up a ladder on the Xiangling city wall and forcibly went to the city to fight.

All of a sudden, the city wall was in danger of being taken, Huang Zhong became anxious and scolded Zhang Ji, but Zhang Ji also scolded him, blaming him for the lack of soldiers he brought.

Seeing that they were about to occupy the city wall, the Southern Huns naturally stepped up their offensive and did not hesitate to do so.

The current critical situation is actually caused by three parties.

The Southern Huns were desperate and decided to trade death for life. To put it bluntly, they were gamblers. If they lost the bet, they would die. If they won, they would live.

On Huang Zhong's side, Huang Zhong thought that Zhang Ji should leave so quickly, so there should be a lot of troops. In addition, he found that the enemy's troops were actually very few, so Huang Zhong had an idea.

Huang Zhong wanted to lure the enemy down from the city wall to the big battlefield, and use his strength advantage and the width of the battlefield to defeat the opponent.

So Huang Zhong sent only a part of the soldiers to fight on the city wall. Huang Zhong played the semaphore to Zhang Ji again, thinking that the other party should understand it.

So what did Zhang Ji think?

On Zhang Ji's side, Zhang Ji is not from the Immortal Master System, he was recruited to recruit security, so he didn't understand the meaning of Huang Zhong's semaphore, he thought Huang Zhong's semaphore meant to retreat.

But where can we retreat in the city wall battle?

So when Zhang Ji found out that there were only some soldiers on the city wall, he naturally brought the soldiers he led to support the city wall.

At the same time, Zhang Ji did not discover that the enemy's troops were actually very small like Huang Zhong did, so from the beginning to the end, Zhang Ji believed that he was facing an enemy with more than 6,000 troops.

And I only have 1500 troops, that is to say, I will add Huang Zhong's troops, and also add the information that Huang Zhong estimated that there were less than 500 troops when he came.

Therefore, Zhang Ji believed that with a small force, he would never be able to win a frontal battle. If he wanted to win, he had to defend the city, and they had to take advantage of the city defense.

"Where's the **** Huang Hansheng?"

Zhang Ji cut down a Southern Huns rushing over with his ring-shou knife, kicked down another Southern Huns who climbed up a ladder, turned his head and asked.

"promise!"

Those who answered Zhang Ji were the rare responses from the Imperial Forest Army. Zhang Ji, who turned his head to see this scene, was deeply saddened and extremely angry.

The huge change in Zhang Ji's heart triggered the items in his arms, and the temperature suddenly rose from 0 degrees and burst into blooming green light.

Seeing the sudden appearance of green, Zhang Ji was shocked and wanted to take out this item, but it was impossible for him to do this action during the battle.

So Zhang Ji hurriedly withdrew from the battle, and then he had time to reach into his arms, took out the object whose temperature was rising rapidly, and threw it on the ground.

The object in front of him was a palm-sized mirror with a thickness of five or six centimeters, but it was now torn apart.

But Zhang Ji was stunned when he saw the scene in front of him, because this Qingxin mirror was given to him by Li Ru and Jia Xu, saying that it can be used as an ice object. It can be cool in summer.

In fact, Qingxinjing can indeed be used as an ice object, as Li Ru and Jia Xu said.

So the question is, what is ice.

Ice objects, to put it simply, are refrigerators, air conditioners, central air conditioners and other things that can lower or raise the temperature.

And if more specifically, it is the temperature control system, referred to as temperature control.

Ah, you said, refrigerators, air conditioners, and central air conditioners have built-in temperature control systems?

This is about temperature.

Temperature is a physical quantity that expresses the degree of hot or cold of an object. Microscopically speaking, it refers to the intensity of thermal motion of object molecules.

Temperature can only be measured indirectly through certain characteristics of objects that change with temperature, and the scale used to measure the temperature of objects is called a temperature scale.

It specifies the reading starting point (zero point) of temperature and the basic unit of measuring temperature.

The SI unit is the thermodynamic temperature scale (K). Other temperature scales that are widely used internationally are Fahrenheit (°F), Celsius (°C) and the International Practical Temperature Scale.

Fahrenheit (Fahrenheit) and Celsius (Centigrade) are both units used to measure temperature.

Many countries in the world including China use Celsius, the United States and some other English-speaking countries use Fahrenheit and less commonly Celsius.

It is named after its inventor, Gabriel D. Fahrenheit (1681-1736), and has a freezing point of 32°F and a boiling point of 211.9532°F.

In 1714, the German Fahrenheit used mercury as the temperature measuring medium to make a glass mercury thermometer. The temperature of the mixture of ammonium chloride and ice water was selected as zero degrees of the thermometer, and the temperature of the human body was 100 degrees of the thermometer. The thermometer is divided into 100 parts from 0 degrees to 100 degrees according to the volume expansion distance of mercury, and each part is 1 degree Fahrenheit, which is recorded as "1℉".

Most countries in the world, including domestic countries, use Celsius; only 5 countries in the world use Fahrenheit, including the Bahamas, Belize, British Cayman Islands, Palau, the United States of America and other dependent territories (Puerto Rico, Guam, U.S. Virgin Islands).

The inventor of the Celsius temperature scale is Anders Celsius (1701—1744), whose freezing point is 0°C and boiling point is 99.974°C.

In 1740, the Swedish Celsius (Celsius) proposed that under standard atmospheric pressure, the temperature of the ice-water mixture should be 0 degrees, and the boiling temperature of water should be 99.974 degrees.

The glass mercury thermometer is graduated according to these two fixed temperature points of water.

Two points are divided into 100 equal parts, and each part is called 1 degree Celsius.

Recorded as 1°C. The Celsius temperature has been included in the International System of Units ~lightnovelpub.net~ In physics, the Celsius temperature is expressed as t, and the absolute temperature (unit: Kelvin) is expressed as T, and the definition of Celsius is t=T-273.15.

Celsius is a specialization instead of Kelvin when expressing Celsius temperature.

Name, numerically 1K=1℃.

The relationship between Celsius and Fahrenheit: T℉=1.8t℃+32 (t is the temperature in Celsius, T is the temperature in Fahrenheit)

The relationship between Celsius temperature and Kelvin temperature: °K=℃+273.15

From the point of view of molecular kinetic theory, temperature is the sign of the average kinetic energy of object molecular motion.

Temperature is the collective performance of the thermal motion of a large number of molecules, which contains statistical significance.

For individual molecules, temperature is meaningless. The degree of hotness or coldness measured on any of several arbitrary scales according to an observable phenomenon, such as the expansion of a column of mercury.

Temperature is a manifestation of the translational kinetic energy between molecules in an object.

The faster the molecular motion, that is, the higher the temperature, the hotter the object.

The slower the molecular motion, that is, the lower the temperature, the colder the object.

From the point of view of molecular motion theory, temperature is the symbol of the average kinetic energy of molecular motion of an object, and temperature is the collective performance of molecular thermal motion, which has statistical significance.

When the temperature reaches a certain level, the oxygen substance in the air is burned and turned into a flame to transfer heat, which can lead to the melting of the substance, and when the temperature reaches the extreme, all matter (mass) and energy will be destroyed.
