"I see, it uses the principle of teleportation circles to communicate, no wonder it is so large, inefficient and expensive." Chu Yun ruthlessly disassembled the communication equipment directly to watch.

"In comparison, the structure of the magic tentacles is much more reasonable, using the principle of magic element waves for point-to-point signal transmission."

"However, because the equipment is too small, the power is not enough, and it can only be maintained at 30 kilometers."

"Building base stations at intervals can solve this problem, but it's too expensive and cumbersome to maintain."

"If the number reaches a certain size, using other tentacles to jump can solve this problem, but only the tentacles that are active and have energy supply can be used as a springboard, and there are also privacy leaks and other problems."

……

Chu Yun muttered to himself while studying and comparing the advantages and disadvantages of the two communication devices.

Xilu had already stopped taking notes on refining the medicine, and was intently watching the master's supersolution analysis process beside Chu Yun.

I don't understand anything, but I always feel like I'm amazing.

Avril was still looking at the magazine on the table, but at this time Hill finally woke up, and she reluctantly put down the magazine and came to Chu Yun's side.

"Chu Yun, will you introduce it to Hill?" Avril whispered.

Hill looked at Avril with a wary gaze, while Shelv was reluctant with a hint of anticipation, hoping that Avril could treat her sister well.

Chu Yun scratched his head, and didn't find the most reasonable solution for a while, he stopped his movements and got up and came to Hill's side.

"Ciel, this is Sister Avril, say hello to her." Chu Yun patted Hill's little head and said.

Hill looked at Avril a little timidly, and opened his mouth slightly, "Avril...... Sister...... Sister. ”

Avril was overjoyed when she saw Hill's cute appearance, and what she liked most was cute things.

Avril took out a bag of exquisite candies from the spatial ring, these candies were all in the shape of various small animals and flowers, and Ciel's eyes lit up when he looked at it.

"Ciel, this is a little gift I prepared for you, it's delicious."

In addition to candy, Avril also brought a lot of expensive and exquisite snacks, which won Hill's favor at once.

"Sister Avril, can these things be divided between Sister Shiro and Mia?" Ciel looked at his sister with a sugar melon

Avril's smile widened: "Of course, it's up to you who you want to give it to." ”

Hill breathed a sigh of relief and distributed the snacks to Shilu and Mia, and then came to Chu Yun, who had returned to his research.

"Brother Chu Yun......"

"Huh?"

"Brother has dirty hands, Ciel feed you. Hee-hee~"

Worthy of being Hill's little angel, Chu Yun felt that his heart was about to melt.

With a good start, the atmosphere in the room suddenly eased a lot, and Chu Yun even took out the one he bought before, and the world's popular board game made the four of them have fun and deepen their relationship.

By noon, when the trial was about to begin in the central square, Hill had already accepted Avril's beautiful and gentle new sister.

"Chu Yun, are you going to see the public trial?" Avril turned her head to look at Chu Yun and asked.

Chu Yun shook his head, now he just wanted to find the best communication plan, and he didn't have time to pay attention to this little thing.

"Although the deputy city lord has confessed, I, as a party to the incident, will still go over there as a witness in a while. After all, several nobles died at the banquet. Avril doesn't like to be in public either, but it's better to be close to her.

"Before I came, my father and the lord of the city also entrusted me to invite you to the public trial. Of course, if you don't want to, you can also go, and I'll explain to them then, after all, the church will participate as an invited jury at that time, and they seem to have a lot of contradictions with you. ”

Hearing the word church, Chu Yun suddenly came to his senses, after all, things like holy water still have to be taken from the church. He didn't think that the so-called holy water obtained by ordinary people could meet the conditions for improving the experience value, and that kind of holy water was just ordinary river water blessed by magic.

"The church is there, so I'll have to check it out!" Chu Yun smiled and collected the things on the ground into the space.

"Brother Chu Yun, are you all leaving? What is a public trial? Hill also wanted to go with everyone. Xiao Xi'er tilted her head to look at Chu Yun.

"Hill is still young, so stay here." Fearing that something bad would happen in the near future, Shilu hurriedly stopped Ciel.

Hill was still very obedient and reluctant to stay, but she soon found that the window could see the square side, and she came to the windowsill to join in the fun.

Chu Yun and Avril came downstairs, and the carriage of the Viscount's family had been waiting under for a long time, and when they saw Chu Yun also appearing, the old butler hurriedly stepped forward to say hello.

The central square is crowded, but fortunately there is a special passage for the nobility, and the most central area is also reserved for the nobles and celebrities to sit.

Although Chu Yun is still only a homeless person during the review period, there is Miss Avril Lavigne, not to mention that he is still one of the protagonists of this incident, so he is also arranged in the top position.

Seeing the appearance of Chu Yun and Avril, everyone immediately shifted their attention to the two of them.

"Oh my God, Miss Avril Lavigne's illness has really been cured!"

"Miss Avril is still as beautiful as ever, if only she could be Miss Avril's knightly retinue."

"Dream, I heard that Miss Avril and Chu Yun next to her are already getting better, and they will get married next month!"

"What! This is impossible, how can my goddess marry someone else! ”

……

The crowd was mixed with all kinds of strange remarks, and Avril was a little shy and secretly glanced at Chu Yun. As a result, Chu Yun didn't pay attention to him at all, but looked at Vladis in the distance in a daze, and the smile on the corner of his mouth seemed to see a cooked duck.

Avril was a little frustrated, as if she was always so unattractive in Chu Yun's eyes, and she couldn't let him stay even a minute longer.

In fact, what Avril didn't know was that the reason why she paid so much attention to and cared about Chu Yun, in addition to being rescued by Chu Yun many times, the bigger reason was that Chu Yun's blood flowed in her body.

To some extent, Avril is also Chu Yun's daughter, and the blood connection is even closer than ordinary blood relatives.

Therefore, whenever Avril approached Chu Yun, she would feel extremely cordial, and unconsciously hit all her attention on Chu Yun, and this scene was even more obvious in the eyes of people who didn't know.

In the eyes of outsiders, Avril's eyes looked at Chu Yun affectionately as if she was looking for a lover.

"Alas, my daughter has grown up after all." Viscount Raymond couldn't help but sigh when he saw his daughter's appearance, a good cabbage will be arched by a pig after all.

No matter how good a son-in-law is, he is a scum in front of his father-in-law.

Chu Yun didn't notice this, he went straight to the place next to Bishop Vladis and sat down, and at the same time said provocatively: "Archbishop Vladis, today's face is not very good. ”

Vladis's face was already so dark that he could squeeze out the ink, and he longed for a ball of holy light to smash into Chu Yun's face.
