Rex is busy.

In a blink of an eye, Rex had already arrived at the main city of Gilness for three days. During these three days, Rex was very busy. Ordinary people could not see Rex at all. Even Gwen and Allen, it was not easy for these two to see Rex. Rex's whereabouts were too strange and could only be described as elusive.

In the past few days, the situation in the old land of Gilness is improving. With the continuous support of materials, all disasters have become paper tigers.

In order to stabilize, King Gene made up his mind. All the supplies that Rex obtained from Kelthus were waved by King Gene and sent to the main city of Gilness.

Although the supplies had not arrived yet, the news had arrived, all Rex's concerns about the old land of Gilness disappeared. With this batch of supplies, there would be no problems in the old land of Gilness.

That's why the scene in front of me came into being. Rex was checking the root cause of the heavy snow.

The reason for the snow is that everything has scientific basis. Rex deeply explores the memories in his mind.

Regarding the original snowing, Rex has this memory. In the primary school textbook, the changes in the weather, why it rains or snows, it all explains. After Rex traveled through time, the perverted memory, the brain, the memory is like a computer, and the memory is like a file, and it is stored in the brain. As long as Rex calls it, there is no difficulty at all.

After thinking hard for a while, this memory was reminiscent of Rex.

Clouds are composed of many small water droplets and small ice crystals, and raindrops and snowflakes are formed by the growth and growth of these small water droplets and small ice crystals.

In the water and clouds, cloud droplets are all small droplets. They mainly increase into raindrops by continuing to condense and collide with each other.

Ice clouds are composed of tiny ice crystals. When these small ice crystals collide with each other, the surface of the ice crystals will heat up and melt a little, and will get stuck in each other and freeze again. Repeat this many times, and the ice crystals will increase.

In addition, there is also water vapor in the clouds, so ice crystals can continue to grow by condensation. However, ice clouds are generally very high and not thick, and there is not much water vapor there. Condensation grows very slowly and there are not many opportunities for collision with each other, so they cannot grow to a large extent and form precipitation. Even if precipitation is caused, it is often evaporated during the descent and rarely falls to the ground.

The memory records are extremely detailed. Rex has to thank nine years of compulsory education for this point. He has been of great help to Rex. Although there are many things that were forgotten in his previous life because of the age of time, it is different at this moment. Rex only needs to think about it carefully and discover knowledge that is useful to him.

This knowledge is of great help to Rex. If you want to search for the heavy snow, it is crucial to see if it is artificial, that is, how the snow is formed.

There is no research on this aspect in the Azeroth world. It is not without technology in the Azeroth world, but this technology is just a derivative of war. All directions are to pursue weapons and power. There are not many places to use in other aspects. This is why the Azeroth world's productivity is not high, and its population is still low and there is no flooding.

The main forms of each world are different, and the final development direction is also different. In the Azeroth world, there are professionals. This magical power, technology is rarely used in life, except for making weapons. The most fundamental reason is that it has no time.

Sitting on a snow pile and looking at the snow-capped Gilness, Rex continued to consider the formation of the snow, and a message kept flashing in his mind.

The most conducive to cloud growth is hybrid cloud.

The hybrid cloud is composed of small ice crystals and supercooled water droplets.

When a ball of air has reached saturation for the ice crystal, the water droplets have not reached saturation. At this time, the water vapor in the cloud condenses on the surface of the ice crystal, while the supercooled water droplets are evaporating. At this time, the ice crystal "adsorbs" water vapor from the supercooled water droplets. In this case, the ice crystal grows very fast. In addition, the supercooled water is very unstable.

As soon as you touch it, it will freeze. Therefore, in the mixed cloud, when the supercooled water droplets collide with the ice crystal, it will freeze and stick to the surface of the ice crystal, causing it to grow rapidly. When the small ice crystal increases to overcome the resistance and buoyancy of the air, it falls to the ground, which is snowflakes.

Rex has known the reason for the formation of snow. The next step is to observe carefully when it snows and see if this is formed naturally or if it is promoted by other forces.

This opportunity doesn't take long to wait for Rex. The weather in the old Gilness area, except for the day when Rex came, was sunny, the other days were not very good. Especially today, from the perspective of Rex looking up at the sky, you can see clearly that the dark clouds in the sky were pressing down on the top of the sky, and the whole earth was relatively dark. This was a cloudy day, and the accumulated black clouds in the sky also told Rex that the snow was about to fall.

"Your Highness, I'm urgently reporting!" A guard riding a mount galloped towards Rex. He turned over and dismounted before and after reaching Rex. He jumped beautifully and landed steadily on the ground. His legs bent slightly, and he took a few steps, shouted loudly.

"Gianna is here?" Rex said in a deep voice when he saw the visitor.

Rex said this sentence with some particularity. As early as when Rex came to the old land of Gilness, he received news that Gianna found Egwen and was planning to come to Gilness. Rex spent a few days on his way and stayed in Gilness for a few more days. One by one and the other was quite a while, but this time was not enough compared to coming to the Eastern Kingdom from the Kalimdo continent.

However, this is based on the fact that Jaina and the others were rushing by boat, which took longer. However, there are many ways to go to the Eastern Kingdom from the Kalimdo continent. The easiest one is to take a boat. The goblin caravan is happy to serve. By boarding the boat in Ratchet City, you can reach the treasure bay. The second way is to use the portal.

This method is quick and can eliminate the large amount of time wasted on a boat. However, if you want to use a portal, the only rigid requirement is to have a certain identity. In order to resist the invasion of the Burning Legion, the alliance army went from the Eastern Kingdom to the fixed portal in Kalimdo, and did not destroy the fixed portal because of the victory of the war.

The construction of this fixed portal costs a lot. If it is destroyed, it will be a waste, so both the Alliance and the Night Elf have been retained by default.

For more than half a year, this fixed portal was still open, but it was not used on a large scale. The night elves restricted this aspect and could not be used by ordinary people, but Gianna was obviously not among the restrictions.

With Jaina's ability, she didn't come for so many days, which is considered slow. Jaina can directly use the portal to reach the area of ​​the night elves, and then use a fixed portal to reach the Eastern Kingdom. Half a day is enough, and it has taken so many days so far, which is other reasons.

"Gianna and the others have arrived at the main city of Gilness and are looking for His Highness. Lord Allen asked me to send me to ask His Highness back," said the guard.

"You go back and report first, and I'll be there soon," Rex waved his hand and sent off the guards and stood up from the snow pile.

Jaina's problem reminded Rex of the fixed portal. The fixed portal has been stuck by the night elves, which made Rex feel a pity. You should know that the fixed portal is now limited by the people used, which hinders the development of Lordaeron's main city. With a fixed portal not far from Lordaeron's main city, if the fixed portal can complete the important task of communicating the two continents, the prosperity of Lordaeron's main city will definitely be further improved.

This is also the consideration of Rex when establishing a fixed portal, and using a fixed portal to promote the prosperity and development of the two continents.

Rex's calculations are very good, but the Night Elf is not powerful.

Because of their obstruction, it cannot develop now, and the caravan cannot lead freely. In the past six months, Rex felt a pity, but did not take any action. In the Holy Mountain of Haigar, the night elves have been staying for a long time. The night elves have always built the main city on the Holy Mountain of Haigar because of the existence of the World Tree. The night elves mainly rely on the Tree of World, but now the Tree of World is finished and has been destroyed by Archmond. The night elves will never stay in the Holy Mountain of Haigar for a long time. This is exactly the case in the original history. The night elves finally retreated to other places.

This is also the reason why the night elves created another world tree. The environment of the Holy Mountain of Haigar is also a factor to be considered. The environmental improvement of the Holy Mountain of Haigar is gradually changing, and the pollution caused by the demons has begun to be reflected in the Holy Mountain of Haigar. Because of the weak space, there are monsters in the distorted void visits from time to time, and suddenly they emerge from the Holy Mountain of Haigar, and the night elves suffer a lot.

In more than half a year, in the information obtained by Rex, the night elves have proposed to relocate more than once, but there is no further information every time. They are forced to suppress them by Tyrande.

Walking down the snow, Rex thought about things and headed towards the main city of Gilness. Suddenly Rex stopped his steps, and a hint of wet appeared on his face.

It's snowing. (To be continued...)
