Chapter 084 Adventure in the Unknown World

Zhou Wenwen waved and called, "Tisi, the Palace of Doom!"

The next moment, Tis and the two doomsday knights appeared next to Zhou Wenwen through teleportation.

Needless to say, Zhou Wenwen said that Tis and the Doomsday Palace, who saw this scene with the help of the Doomsday Knight, instantly understood what Zhou Wenwen was thinking.

So Tis asked, "You want to go?"

"Well, I want to go over and check out the situation. I can't leave this thing here."

Tisi said, "Then I will go too."

But Zhou Wenwen shook his head and said, "No! The Doomsday Knight must send someone to follow me."

"why?"

Tis asked in confusion.

Zhou Wenwen had no choice but to explain, "The last time you traveled through time, you lost your strength. Now that the giant snake hasn't been killed, I might as well let you look after the house."

Tisi had no choice but to promise Zhou Wenwen to guard the family. Before leaving, he gave Zhou Wenwen a set of armor.

An example of an irreversible process is the free expansion process into a vacuum.

That is, the gas initially occupies only part of the container, and then fills the rest of the original vacuum).

That is, the process in which two objects with different temperatures reach thermal equilibrium through thermal contact.

But because of these processes, it cannot be restored to its original state without causing external influences.

So strictly speaking, all macroscopic processes occurring in a system composed of a large number of particles are irreversible.

Because in mechanical movement, there is always friction and loss.

In the process of heat transfer, heat is always transferred from hotter parts to cooler parts.

The total energy during these processes is still conserved and does not violate the first law of thermodynamics.

Therefore, there must be other basic laws that will limit the directions in which the actual process can proceed.

This is the second law of thermodynamics, and the state function entropy introduced on this basis.

The second law of thermodynamics is the thermodynamic law that limits the direction of actual thermodynamic processes.

It confirms that the principle of entropy increase is established - there is a state function entropy in a thermodynamic system that reaches equilibrium. The entropy of an isolated system does not decrease, and the entropy is maximum when it reaches equilibrium.

In other words, the second law of thermodynamics requires that the process occurring in an isolated system proceeds in the direction of increasing entropy, which is called the entropy criterion.

Together with the first law of thermodynamics and the third law of thermodynamics, it forms the basis of thermodynamic theory.

The Carnot theorem derived from it points out the direction and limit of improving the economy of heat engines and refrigeration machines.

However, experience points out that thermal power conversion is irreversible, and the irreversibility of thermal power conversion can only be observed in a large number of heat engine cycles.

It is impossible to make a heat engine that only absorbs heat from a high-temperature heat source and does not release heat to a low-temperature heat source.

Therefore, after summarizing a large amount of practice, we have concluded that it is impossible for us to absorb heat from a single heat source and turn it completely into useful work without causing other effects.

This is the Kelvin expression of the second law of thermodynamics.

It negates the possibility of making a perpetual motion machine of the second type.

In addition to the irreversibility of thermal work conversion, heat transfer is also irreversible. Heat is always transferred spontaneously from high-temperature objects to low-temperature objects, and the reverse process cannot proceed spontaneously.

On the basis of a large number of experiments, Clausius concluded another expression of the second law of thermodynamics - it is impossible to transfer heat from a low-temperature object to a high-temperature object without producing other effects.

The probability of a macrostate appearing is related to the number of microstates it contains.

The number of microstates corresponding to a macrostate is called thermodynamic probability.

The greater the thermodynamic probability, the greater the chance that this macroscopic state will be observed in experiments.

The equilibrium state is the macroscopic state with the largest thermodynamic probability W and has a definite value. Therefore, if the entropy of the equilibrium state is defined as S=klnW using Boltzmann's formula, then the system will spontaneously transition from a state with a small probability to a state with a probability of The irreversible process of a larger state is a process of entropy increase, thus explaining the principle of entropy increase at a microscopic level.

The third law of thermodynamics refers to the basic law that must follow when the temperature approaches absolute zero.

It is summarized on the basis of a large number of experimental observations, and its main content is Nernst's theorem and the absolute zero inaccessibility principle derived from it.

Therefore, an external shield was designed in the Temple of Doom, and a plug-in method was used to solve the problem of the external flame caused by Gem Knight 0155 falling into the earth at high speed.

In February, Gem Knight version 2 was approved, allowing mass production. The name was changed to Sky Knight, and the version was 0155, indicating that it was finalized in February 190.2 AD.

From then on, in addition to the three delivery warehouses on the Guardian platform, there were also Flint Knights, 15 delivery warehouses, and 4 delivery warehouses on the newly built platform 2 in April, all of which were Sky Knights.

Of course, after the Temple of Doom completed the final design of the Sky Knight, it also started tinkering with updates to the Sky Knight, but it was always just a small patch.

......

"Damn it, where's that bastard Huang Hansheng?"

Zhang Ji was answered by a rare response from the imperial guards. Zhang Ji, who turned around and saw this scene, suddenly felt 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 reached into his arms, took out the item whose temperature had risen rapidly, and threw it on the ground.

It was a mirror the size of a palm and five to six centimeters thick, but it was now torn apart.

The next second, the temperature control system in the mirror triggers the signal transmitter and emits a signal. The transmission tower arranged on the Taihang Mountains receives the transmitted signal and immediately transmits the signal to the communication satellite in geostationary orbit. The communication satellite then transmits the signal. Passed to the guardian platform through the relay station.

When the Guardian Platform received the signal and located its position, the Doomsday Palace determined based on the situation that 6 delivery warehouses needed to be delivered, so the people in Xiangling were lucky enough to see this scene:

I saw 6 large fireballs crossing a diagonal line in the sky before falling accurately into the Huns. Boom!

The gas explosion was set off on the spot, and many Southern Huns were thrown into the air and fell to death on the spot. But more importantly, the formation of the Southern Huns was messed up and their morale collapsed.

Seeing this scene, Huang Zhong and Zhang Ji immediately realized that this was a good opportunity, and each led the imperial army to charge. The Southern Huns, who were already panicking, now had no chance of victory and fled in all directions.

On May 5, Huang Zhong and Zhang Ji spent two days to capture more than a thousand escaped Huns from the South and imprisoned them in Xiangling under the guard of Zhang Ji. After that, Huang Zhong led 13 imperial troops to Pingzhou.
