The Antu Tavern is a large place, and in a small round table deep in the corner, there are three people who are dressed a little strangely and quietly drinking fruit wine.

The sound of discussion outside kept coming, and they all seemed to be deaf, it was Xia Yu and the others.

After a long time, Xiaoman muttered: "It seems that it really makes a big fuss......"

This girl is really an afterthought!

Xia Yu has always felt that Xiaoman should not be from an ordinary small family, not to mention anything else, the faint nobility and self-confidence revealed in his bones, although it is worse than Song Zixuan, it is not too far.

He later inquired with Qiangzi, but Qiangzi didn't know Xiaoman's origins, only knew that she had only been in Tianqing for half a year, and she called Uncle Hu.

That night's battle, the three of them left through the back door of Tianqing's station, but they didn't dare to go back to Xia Yu's house, and finally found a small hotel to live in.

When I inquired the next day, I learned that more than a dozen old and weak monks such as Storm Bear and Lao Sheng were all fighting to the death, and more than half of them were killed on the spot!

The three of them were frightened, but they didn't dare to go back to see it, so they simply disguised themselves and came to the most lively Antu Tavern nearby, constantly inquiring about the follow-up news.

However, there was no new news in the city all day, and it was just some discussion of the battle that night.

When I came back early this morning, I heard that the head of the tiger regiment got the news from nowhere, so he rushed back to the city without stopping, and a "Xuanwu halberd" killed the Zhang family with a river of blood!

"Xiaoman, this ...... I don't blame you for this, you were here to get ahead!" Qiangzi also lowered his voice and clenched his fists: "Damn! I really want to be like the head of the tiger and kill into the Zhang family to avenge Uncle Lao Sheng and Uncle Tyrant Xiong!"

Xia Yu knows Qiangzi's character, he has no relatives since the death of his parents, and he will cherish anyone who treats him well.

Seeing that Qiangzi was uncomfortable, he gently patted Qiangzi's shoulder: "Maybe there is a chance, I will accompany you then." ”

"Can't wait that long!" Xiao Man suddenly spoke, her eyes were bright, as if she had made up some kind of determination, and suddenly looked at Xia Yu and said, "Xia Yu, do you know where you can call the source machine?

After such a big incident, she finally felt that she could no longer be willful and was ready to ask for help from her family.

But she didn't know how to face Uncle Tiger, so she had to ask Xia Yu about it.

Xia Yu is a person, Qiangzi is on her lips almost every day, and she doesn't feel unfamiliar when she shouts this name, as if she has known friends for a long time.

Moreover, Xia Yu's composure and decisiveness in the past two days also impressed her.

From childhood to adulthood, there are countless excellent peers around her, but Xia Yu in front of her has an indescribable special temperament.

"This, I really don't know where there is an interstate source machine...... Xia Yu has heard of such an agency.

In this world, the average person simply does not have this need. Because it is not easy to travel, many people stay in the same city all their lives, so there are no institutions that offer this kind of service.

When he was in the laboratory, he heard people say that the source signal machine in this world works similarly to the earth, and it is also necessary to set up a source version of the communication base station, and then communicate through a certain frequency band signal.

However, due to the unique influence of source energy between heaven and earth, this kind of signal transmission is almost incomparable with the earth, and it seems to be much more difficult, so no mobile communication equipment has been born so far.

As for ultra-long-distance communication, it exists, but it is extremely expensive, after all, the cost of laying base stations in the field is too great.

Seeing Xiaoman's delicate face showing a look of disappointment, Xia Yu suddenly thought of someone: "Wait a minute, I can find someone to help you try." ”

............

Qu Bailing has been very busy lately.

The Xuan Arc structure was not his first creation, but no one in the Federation had ever researched too many practical source boxes on this structure.

An important reason is that the speed of those arcs is not easy to control, and the energy conversion efficiency is low as a whole.

After more than a decade of sleepless experimentation, he was able to increase his energy efficiency from 82% to 86% – thanks largely to an unexpected burst of inspiration – but no further than that.

With an energy efficiency of 86%, it is barely usable, enough for a Grade 2 source crystal.

However, counting the cost of alloy armor and silk winding materials equipped with the "Six-Lock Armor", it is still high.

The cost of this kind of mechanism, which is designed for large-scale installation, must be strictly controlled, because the price itself is one of the important factors in whether the final bid will be won.

This state guard bidding is very important to Qu Bailing.

In addition to gaining fame and fortune, he has been unable to break through the threshold of level 4 for a long time, and he has always hoped to go to the headquarters of the Federation Organ Division Association in the Iron Abyss Holy City to study, and a good result is very necessary.

After all, he didn't want to be an apprentice in the past, but also wanted to apply for his own laboratory, so excellent grades and financial resources were indispensable.

But the Xuan arc structure is too difficult after all, and there is nothing he can do about it at this point.

On the one hand, he could only continue to try his luck, and on the other hand, he was waiting for the Longxing Chamber of Commerce to arrive in Luotong soon, to see if he could bring more suitable alloy materials.

"Hey, I don't know if Longxing will surprise himself this time!"

With a light sigh, he stretched his somewhat stiff body slightly, intending to go out for a walk to relax his mind.

As soon as I went out, I saw the little guy named Xia Yu at the door, and said strangely: "Xia Yu, why are you here? Dongyuan should give you a holiday for the past two days, right?"

For the young man in front of him, Qu Bailing still admired it very much.

When he was guiding those young people a while ago, Xia Yu may have the worst foundation, but he has the most lively thinking, and he learned the source array symbol cluster textbook he gave him very quickly, and his attitude has always been very good.

In his heart, Xia Yu had even entered the list of candidate disciples, but he still needed to finish this bidding project and conduct a collective assessment.

"Master Qu, I'm sorry to disturb you!" Xia Yu waited here for three hours, but his expression was still respectful: "I have a friend who urgently needs to try out the interstate source machine, and I really can't think of a way, so I can only come and disturb." ”

"Ha, that's easy to say!" Qu Bailing originally wanted to take a walk, and immediately said, "Where is your friend?"

Xia Yu's face was happy: "Thank you, Master Qu! They are all waiting nearby, I'll call them immediately!"

Xu is for the convenience of traveling to and from the laboratory, Qu Bailing's residence is not far away.

His home is not large, and the furnishings are very simple.

Xia Yu heard that he had never married since losing his wife in middle age, and only had one daughter who was a teacher in a certain higher education, but he was not in Chong Yanzhou, so Qu Bailing had been living alone.

Xiao Man entered the room to dial the gap of the source machine, and Xia Yu also asked about the current progress of the experiment.

Qu Bailing didn't hide it from him: "You also saw it in the last experiment, the current six-lock armor is too high in energy consumption under the guarantee of defense effect, I am trying to improve the efficiency of source energy conversion, but I am not satisfied." ”

"Then what about starting with the material, such as trying the synthesis of a new alloy?" Xia Yu thought about it, this seemed to be the only way.

"Haha, it's not bad that you can think of this, but materials science is one of the largest branches of mechanical arts, and the doorway in it is deep, Luo Tong doesn't have a laboratory that can handle this aspect, and Dongyuan is also waiting for the foreign chamber of commerce to come!"

"What the master said was that I was thinking too simply. Xia Yu scratched his head, a thought vaguely flashed in his heart, and he put it down for the time being.
