Chapter 189 The Plan Is Being Implemented

Chapter 190 The plan is being implemented

If you want to artificially change the sky and create a rainstorm that covers most of the city, you must first understand the principle of rainfall formation.

Recalling the knowledge he had learned in the past, Xu Yue looked at the clouds floating around him, reached out and touched a ball of white cotton wool that looked like cotton candy, but he didn't feel anything, only wet and cold. When he took his hand back, his palm was covered with tiny water droplets.

The so-called cloud is essentially a large amount of water vapor that condenses into small water droplets due to the cold when it encounters cold air at high altitude. The diameter of these small water droplets is generally only about 0.01 to 0.02 mm.

The tiny volume allows these water droplets to be supported by the airflow in the air, so that they can be suspended in the sky. When a large number of small water droplets gather together, they form the clouds we often see.

As for the formation of rainfall, it is the large number of small water droplets in the clouds that increase in volume after fusion or adsorption. When the volume weight reaches a certain level, the rising air flow cannot support it, and the water droplets will fall from the sky under the action of gravity, causing rainfall.

In summary, it is not difficult to achieve artificial rainfall. You only need to meet the above two conditions.

One is sufficient water vapor, which is the basic condition for the formation of rainfall.

The Dilong Kingdom is adjacent to the Chaotian Mountains in the west. The large amount of water vapor blocked by the tall mountains makes most of the territory in a state of sufficient water vapor and abundant water resources. Therefore, the clouds in the sky are thick all year round, otherwise there is no way to cover the huge volume of the Sun Chaser.

Xu Yue stood on the deck of the Sun Chaser, with a pair of purple enchanting wings behind him, driving him into the sky.

The wings rolled up the wind and waves, and after a climb, he reached the top of the cloud layer. Looking down at the fluffy and rolling clouds below, he frowned slightly.

Clouds can generally be divided into two categories: cumulus and stratus. Among them, the rainfall formed by thick and huge cumulonimbus clouds is the most violent, and may even cause thunderstorms.

Now the clouds in the sky are fluffy and white like cotton wool. From the perspective of form, this is obviously the most common cumulus cloud. Although such clouds also meet the basic conditions for rainfall, they are far from what Xu Yue wants.

Therefore, he needs to manually add a large amount of water vapor. As for how to add it, he has already had a plan in mind.

The first condition is met, and then the second one is. In addition to water vapor, in order to quickly induce rainfall, it is also necessary to find a way to promote the rapid condensation of water droplets in the clouds.

To achieve this, the most common method is to throw a large amount of dry ice, silver iodide, salt and other catalysts into the clouds. These substances will cause the water vapor in the clouds to cool and form a large number of ice crystals. These ice crystals are the best condensation nuclei, allowing water droplets to gather and form rainfall.

However, in Dilong Country, a country similar to ancient society, it is basically impossible to collect special materials such as dry ice and silver iodide. There is no condition and material basis for large-scale synthesis. Therefore, he can only use a more cruel method to cause a large-scale forest fire. At the cost of burning the entire forest, a large amount of rising smoke and dust will be produced as the condensation nucleus of the cloud layer to cause a rainstorm.

High in the cloud layer, after reorganizing his plan and confirming that it is roughly feasible, Xu Yue leaned back and fell down. With the flapping of his wings, he turned into a purple line of fire and fell straight to the ground. Before realizing his plan, he still needs to go to the capital of Dilong Country.

The capital of Dilong is called Wujiu City. It was renamed when the guardian beast was established fifty years ago. Its intention is based on the ninth and fourth lines of the Qian Gua of Zhouyi - or leap in the abyss, no fault.

The general interpretation is: the dragon may leap into the sky or stay in the abyss. As long as it moves forward according to the needs of the situation, there will be no mistakes.

At that time, the people of Dilong country had high expectations for the guardian beast Longyuan, hoping that it could lead the Dilong race to completely transform into underground true dragons, and the whole country would benefit from it. But at the same time, they were also afraid that a series of backlashes after failure would cause the whole country to fall.

So they named the beast Longyuan and changed the name of the capital to Wujiu, in order to warn themselves that when they were about to transform, they must not act rashly, but should follow the trend and make advances and retreats with reason. In this way, whether they succeeded or failed, they would not cause too serious damage.

Unfortunately, as fifty years passed, the ancestors of the previous generation gradually aged, and the new descendants who came to power seemed to have forgotten these instructions, leaving only the increasingly inflated ambitions.

From the annual increase in foreign trade prices and the covert contact with the biological geneticists of the Ster country, it can be seen that the current Dilong country has begun to be impatient.

At the main gate of the capital, Xu Yue looked up at the word "Wujiu" on the plaque of the city gate, and a trace of sarcasm flashed in his eyes. In recent years, the style of the Dilong Kingdom is very different from this plaque.

Entering the city, there are a lot of people coming and going on the wide streets, and the shops on both sides are full of hawking sounds, which is very lively. Although the architectural style here is also the ancient Chinese architecture like that of Xuanwu Kingdom, it seems much more lively. The pedestrians are no longer warriors with swords and knives, but mostly merchants and scholars in brocade clothes and jade belts.

The developed agricultural output makes the handicraft industry of Dilong Kingdom also outstanding. The abundance of raw materials such as tea, mulberry, silk, etc. makes the business development extremely fast. The comfortable and peaceful living environment and rich and diverse material resources also make the atmosphere of the whole country tend to be moderate. Therefore, although there are warriors coming and going, most of them are weak and not mainstream.

After wandering around the streets of the capital for a few times, Xu Yue had a general impression of Wujiu City. The value of force was not high, and the vigilance was even more lacking. During the implementation of the plan, these people should not cause much trouble. Trouble, but the missing biogeneticist from St. Petersburg is a potential risk factor and should be paid attention to.

Now that the enemy's intelligence had been basically assessed, he didn't waste time on it. He turned and walked straight towards a pawn shop on the corner of the street, which was one of the shadow organization's hidden contact points in Wujiu City.

As a worldwide assassin organization, Shadow's contact points are all over the major cities in every country on the mainland, and no one is left out. The location maps of these contact points have been handed over to him by the leader's mechanical servant as early as when he became a Shadow Assassin. .

Pushing open the door of the pawn shop, you are faced with a landscape screen. Behind the screen is a tall mahogany counter. Behind the counter, a thin old man is playing with an abacus. The crisp tapping sound of abacus beads echoes gently in the shop. Maybe he noticed the footsteps. The old man stopped what he was doing, looked at Xu Yue who came in, and said with a smile:

"This guest, you want to pawn something?"

Xu Yue didn't reply, he just turned his hand and took out a square token and handed it over. This token was given to him by Guyu when he was in Xingyang City. Before he got the token of 'Qi', this token would It will always be your proof of identity.

Behind the counter, the moment the old man saw the token, the smile on his face turned serious. He stretched out his hands to respectfully receive the token and began to examine it carefully.

This thing is a proof that only the top 100 assassins in the organization will be equipped with it. He can't help but be disrespectful. In this remote and small country with low national power, such big shots are not common.

His eyes first glanced at the most conspicuous shadow organization logo in the center of the token. It was a pattern like three fishhook-shaped patterns circling each other. His fingers brushed the concave and convex patterns around the pattern. After confirming that it was correct, the old man looked at the quilt above the logo. A font surrounded by gold circles has the word "salary" written on it, while the other side of the token has the word "fire" written on it.

‘fireworks…’

Thinking of this familiar code name in his mind, the old man's body trembled, and his face turned pale at first, but then quickly turned red.

A piece of news that just came out from the Xuanwu Kingdom headquarters a few days ago, announcing to all members of the organization, came to his mind.

After the chief rebelled, another shadow assassin emerged, destroying the Bird Gate and defeating the immortal Blackbird. This shadow assassin's codename was Xinhuo.

"Sir, please wait a moment, please wait a moment."
