Chapter 059 The Battle of Xiangling

On the other hand, reality could no longer allow Huang Zhong and Zhang Ji to desert, and the red-eyed Southern Huns, regardless of casualties, erected ladders on the city wall of Xiangling and forced their way to the city to fight.

Suddenly, the city wall was in danger of being seized. Huang Zhong was anxious to see it, and he scolded Zhang Ji. Who knows, Zhang Ji was also scolding him, blaming him for the few 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 pay any price.

The present critical situation is actually caused by three parties.

The Southern Huns were in a hurry and decided to trade death for life. To put it bluntly, they were gamblers.

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

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

Therefore, only a part of the soldiers Huang Zhong sent to the city wall to fight, Huang Zhong signaled 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 and recruited, so how could he understand the meaning of Huang Zhong's semaphore? He thought that Huang Zhong's semaphore meant retreat.

Where can we retreat from the battle of the city wall?

So Zhang Ji discovered that there were only a few soldiers on the city wall, so he naturally brought his soldiers to support the city wall.

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

And he only had 1,500 troops, that is, he added Huang Zhong's troops, plus the intelligence that Huang Zhong estimated less than 500 troops when he arrived.

Therefore, Zhang Ji believes that he, who has few troops, can never win the front. To win, he can only defend the city, and they must take advantage of the city defense.

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

Zhang Ji chopped down a Southern Xiongnu who was rushing over with a knife around the head, and then kicked down a Southern Xiongnu who climbed up from a ladder. He turned his head and asked.

"promise!"

The one who answered Zhang Ji was the rare response from the Imperial Forest Army. Zhang Ji, who turned his head and saw this scene, came from his heart and was extremely angry.

The great change in Zhang Ji's heart triggered the items in his arms, the temperature suddenly rose from 0 degrees and a green light bloomed.

Seeing the green color that suddenly appeared, Zhang Ji was taken aback and wanted to take out this item, but it was impossible for him to make this action during battle.

So Zhang Ji quickly withdrew from the battle, and then he had time to stretch his hand into his arms, took out the item whose temperature was rapidly rising, and threw it there.

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

But Zhang Ji, who saw the scene in front of him, was stunned, because this Qingxin mirror was given to him by Li Ru and Jia Xu. What could be used as an ice object? In the coming June, July and August Cool in summer.

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

So the question arises, what is ice.

Ice, to put it simply, is the refrigerator, air conditioner, central air conditioner and other things that can lower and raise the temperature.

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

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

This has to do with temperature.

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

Temperature can only be measured indirectly through some properties of an object that change with temperature, and the ruler used to measure the temperature of an object is called a temperature scale.

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

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

Both Fahrenheit and Centigrade are units used to measure temperature.

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

It is named after its inventor Gabriel D. Fahrenheit (1681-1736), and its freezing point is 32°F and its boiling point is 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 the zero degree of the thermometer, and the temperature of the human body was 100 degrees of the thermometer. The thermometer is divided into 100 parts according to the volume expansion distance of mercury from 0 degrees to 100 degrees, and each part is 1 degree Fahrenheit, recorded as "1 Fahrenheit".

The vast majority of countries in the world, including domestic ones, use degrees Celsius; only 5 countries in the world use degrees Fahrenheit, including the Bahamas, Belize, the 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 Swedes, 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 mercury-in-glass thermometers are graded according to the two fixed temperature points of water.

Make 100 equal parts between two points, each part is called 1 degree Celsius.

Recorded as 1°C. Celsius has been incorporated into the International System of Units.

In physics, Celsius temperature is expressed as t, absolute temperature (unit: Kelvin) is expressed as T, and the definition of Celsius temperature is t=T-273.15.

Celsius is a specialization in place of Kelvin when expressing Celsius temperature.

Name, numerically 1K=1℃.

The relationship between Celsius temperature and Fahrenheit temperature: T°F=1.8t°C+32 (t is the temperature number in Celsius, T is the temperature number in Fahrenheit)

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

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

Temperature is a collective manifestation of the thermal motion of a large number of molecules ~www.wuxiamtl.com~ with statistical significance.

For individual molecules, temperature is meaningless. The degree of hot or cold on one of several arbitrary scales, based on an observable phenomenon, such as the expansion of a column of mercury.

Temperature is a form of expression of intermolecular translational kinetic energy in an object.

The faster the molecules move, that is, the higher the temperature, the hotter the object.

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

From the point of view of molecular kinematics, temperature is a sign of the average kinetic energy of molecular motion of an object, and temperature is a collective manifestation of molecular thermal motion, which has statistical significance.

When the temperature reaches a certain level, it burns the oxygen in the air and turns it into a flame to transfer heat, which can cause the material to melt and melt.
