But he didn't bother too much about this matter. He just had to go in and do the task. He didn't go to play, so there was no need to waste time. In comparison, it was more important to improve his personal strength, so for the next three days, Xia Yu had been studying illusion sound technology.

The illusion is not as simple as Xia Yu imagined. Although a single illusion is easy to create, such as explosions, footsteps, gunshots, etc., if it is to simulate the sound of a complete animal, it will be more troublesome. The sound of the animal running, walking, roaring, and roaring are very complicated. Moreover, the sound of the animal is dynamic, and each step is necessary to have a corresponding sound effect, which is quite troublesome to cooperate with the phantom technique.

Fortunately, magic is different from science. It often does not require so precise and meticulousness. It is more based on feelings. It is a natural technique, just like speaking. There are no rules and methods to change the shape of the mouth when a human speaks, but have you learned it the same?

Xia Yu continued to practice and finally successfully mastered the sound effects of several animals in three days. However, those fantasy creatures, ghosts, demons, and even more weird things took a lot of time to practice slowly.

Xia Yu also discovered a problem with illusion, that is, the size of the phantom and the sound of the illusion are linked to magic. With his current magic power, he can at most simulate a phantom as big as a Tyrannosaurus Rex, but there will inevitably be some mistakes in details. The smaller the phantom, the easier it will be to simulate. In addition, if you want to match the sound, the more accurate the details will be.

Theoretically, if the mana is strong enough, it can even simulate the holy light effect of a nuclear bomb explosion. Even if there is no explosion, the sound waves alone can still kill people. Of course, this level of magic power can only be YYed in Xia Yu's current situation. It is impossible to achieve it in a short period of time. At most, it can simulate the effect of a grenade explosion.

To improve your illusion limit, you need to constantly improve your magic power and gradually learn the skills of using magic.

At the same time, the material library must be continuously expanded. Illusion magic is a bit similar to video editing. If you want to make illusion more realistic and diverse, you must have enough materials, and this is a long-term accumulation process.

On the evening of the third day, Katrana knocked on Xia Yu's door.

"Master, this is your dress."

Looking at the straight suit in the bag, Xia Yu was speechless, "Did you prepare my clothes for me?"

"Of course, according to the information, it is a very high-end banquet. If you want to collect information at the banquet and enter some circles, it is best not to look too alternative. I am bluntly speaking, the one you usually wear will definitely not do."

He was actually complained about his clothes by his entourage. Xia Yu nodded helplessly, "Okay, I'll just change it back. What about you, are you prepared?"

"Of course." Katrana walked back to her room, and after a while, she changed her clothes and walked out.

"How about it."

Xia Yu's eyes lit up. Although he had known each other for a long time and had already gained some immunity to Katerana's beauty, he was still amazed at this moment. Katerana was wearing a dark purple evening dress that was close to black. The color of the dress formed a sharp contrast with her fair skin. The tight design made her proud figure perfectly appear, with her tall breasts and half-exposed shoulders, which was extremely attractive. Her curly long hair was scattered, slightly messy, her purple eyes were wild and arrogant, with a full queen look, and her slender legs were faintly exposed between the hem of the high-slit skirt.

Just to stop that, Xia Yu subconsciously swallowed his saliva.

At this moment, Katrana has a unique noble temperament, which is different from the wealthy aristocraticism cultivated by humans. It is more like a supreme demeanor that looks down on mortals inadvertently revealed by an extraordinary creature.

It seems that although the body has become human, deep down, Katrana still retains some of the inherent pride of the dragon clan.

Although she didn't seem to realize it herself.

Only in this moment of self-expression can she be revealed.

Katrana was very content with her image, but she still showed a humble attitude in front of Xia Yu, which made Xia Yu very satisfied. Even if she was beautiful, the most important thing for her followers was to be obedient.

"very beautiful."

"Thank you, boss."

Xia Yu looked up and down. Katrana was wearing the women's classic watch that Xia Yu gave her in her hand, which complemented each other, but apart from that, there were no other accessories, which was a bit monotonous.

After thinking about it, Xia Yu took out the bag of jewelry he picked up from the Doomsday Wasteland World from the computer cabinet. At that time, he scattered a lot of good things in the jewelry store in the Wasteland World, but unfortunately most of them were exchanged for food. Only a dozen of the best items were brought back by him, and each one was a fine product.

This will come in handy, "Pick a few pieces to wear."

"Is the master going to give it to me?"

"Of course, choose whatever you want."

Katrana smiled, but she wasn't too excited. Compared with many new things she had come into contact with in this world, these jewelry were not as impactful to her, and she had never worn any kind of jewelry in the past.

But it was still quite funny. She chose a few items very seriously. Instead of choosing those platinum jewelry with unique shapes, she chose a gold necklace with a huge ruby ​​pendant inlaid on it.

Then I chose another golden arm ring and put it on directly.

Generally, gold jewelry is worn by middle-aged and elderly people, and nouveau riche wears it more. Young people will give people a cheesy feeling. However, after wearing it, Katrana will not feel this way at all. Instead, it has a unique sense of dignity and a unique classical beauty. No wonder this woman was able to trick the nobles of Stormwind City into a circle.

Xia Yu also took out his custom watch that he brought from the wasteland world. In fact, he didn't have much feelings about the watch, but it was a high-end banquet, so wearing it would be a good place to wear it.

In the evening, Xia Yu and Katerana came to Xingde Science and Technology Building. Of course, they were not taking a taxi. Katerana rented a luxury car on purpose. Xia Yu thought to himself that women were still careful. If he had changed himself, he would probably have just taken a taxi.

Since he had to do a show, he had to do the full set. Xia Yu got out of the car, opened the car door very gentlemanly, helped Katrana get out of the car, and stood in front of Xingde Technology Building. Xia Yu was about to walk in, but suddenly felt a little strange. The magnificent building in front of him looked familiar, just like he had been here before, but Xia Yu clearly remembered that he had never been here, which was really strange.

"What's wrong?" Katrana asked.

"It's nothing." Xia Yu shook his head, thinking that he must have thought too much. He walked towards the main entrance of the building with Katerana's hand. When he arrived at the door, a welcome guest came to greet him. His eyes looked at Katerana were obviously different, and the eyes he looked at him were a little envy and jealous.
