Chapter 059 Battle of Xiangling

On the other side, reality could no longer tolerate Huang Zhong and Zhang Ji's desertion. The Southern Huns, who were furious, set up ladders on the Xiangling city wall regardless of casualties, and forced their way up to the city to fight.

Suddenly, the city wall was in danger of being captured. Huang Zhong became anxious and scolded Zhang Ji. Unexpectedly, Zhang Ji was also scolding him, blaming him for bringing few soldiers.

When the Southern Huns saw that they were about to capture the city wall, they naturally stepped up their offensive and did so at any cost.

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 lose their lives. If they won the bet, they would live.

On Huang Zhong's side, Huang Zhong thought that if Zhang Ji left so quickly, he should have a lot of troops. In addition, he had previously discovered that the enemy's troops were actually very small, 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 own strength and battlefield width to defeat the opponent.

Therefore, Huang Zhong sent only some soldiers to fight on the city wall. Huang Zhong also sent a semaphore to Zhang Ji, thinking that the other party should understand it.

So what did Zhang Ji think?

As for Zhang Ji, Zhang Ji was not from the Immortal Master System. He was recruited and recruited, so he didn't understand the meaning of the flag Huang Zhong raised. He thought the flag Huang Zhong raised meant retreat.

But where can we retreat in a city wall battle?

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

At the same time, Zhang Ji did not discover that the enemy had very few troops like Huang Zhong did. Therefore, from beginning to end, Zhang Ji believed that he was facing an enemy with more than 6000 troops.

And he only had 1500 troops, so he added Huang Zhong's troops, plus intelligence that Huang Zhong estimated that there were less than 500 troops when he arrived.

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

"Where's the bastard Huang Hansheng?"

Zhang Ji chopped down a Southern Huns who rushed over with his sword, and kicked down a Southern Huns who climbed up from the ladder. He turned around and asked.

"promise!"

Zhang Ji was answered by a rare response from the Royal Forest Army. Zhang Ji turned around and saw this scene, feeling sad and extremely angry.

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

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

So Zhang Ji quickly quit the battle, and then he had time to reach into his arms, take out the item whose temperature was rising rapidly, and throw it away.

The object in front of me is a mirror the size of a palm and five to six centimeters thick, but it is now torn apart.

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. It said that it could be used as an ice object in the coming June, July and August. 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 comes, what is ice.

Ice, to put it simply, refers to things like refrigerators, air conditioners, central air conditioners, etc. that can lower or raise the temperature.

And if we are more specific, it is the temperature control system, or temperature control for short.

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

This involves temperature.

Temperature is a physical quantity that expresses the hotness and coldness of an object. Microscopically speaking, it is the intensity of thermal motion of the molecules of an object.

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

It specifies the starting point for temperature readings (zero point) and the basic unit for measuring temperature.

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

Fahrenheit and 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 often Celsius.

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

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

Most countries in the world, including China, 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, Puerto Rico, Guam, U.S. Virgin Islands).

The inventor of the Celsius temperature scale is Anders Celsius (1701-1744). Its freezing point is 0c and its boiling point is 99.974c.

In 1740, the Swede Celsius proposed to set the temperature of the ice-water mixture as 0 degrees and the boiling temperature of water as 99.974 degrees under standard atmospheric pressure.

A mercury-in-glass thermometer is graduated based on two fixed temperature points of water.

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

Mark it as 1c. The Celsius temperature 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 special term that replaces Kelvin when expressing temperatures in Celsius.

Name, numerically 1K=1c.

The relationship between Celsius temperature and Fahrenheit temperature: Tf=1.8tc+32 (t is the Celsius temperature number, T is the Fahrenheit temperature number)

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

From the perspective of molecular kinetic theory, temperature is a symbol of the average kinetic energy of molecular motion of an object.

Temperature is the collective expression of the thermal motion of a large number of molecules and has statistical significance.

For individual molecules, temperature is meaningless. A degree of hot or cold measured on one of several arbitrary scales based on 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 molecules move, the higher the temperature, and the hotter the object.

The slower the molecules move, that is, the lower the temperature, the colder the object.

From the perspective of molecular kinetic theory, temperature is a symbol of the average kinetic energy of the molecular motion of an object. Temperature is the collective manifestation of the thermal motion of molecules and has statistical significance.

When the temperature reaches a certain level, it burns the oxygen substances in the air and turns them into flames to transfer heat, which can cause the substances to melt and dissolve. When the temperature is extremely high, it destroys all matter (mass) and energy.
