Long Qingyun suddenly slapped his head.

Although this sound transmission stone can transmit sound for thousands of miles or even thousands of miles, it also requires communication signal support.

This is very similar to the mobile phones in Long Qingyun's 21st century before. The reason why mobile phones call requires countless base station signal support.

In this world, the reason why the sound transmission stone can transmit sound from thousands of miles is that it relies on a special energy field.

There are two vast mountains standing between Xitu Hezhou and Zhongtu Shenzhou, extending for hundreds of miles. This special energy field has been blocked and the signal cannot be conveyed at all.

Therefore, there is news that the war situation in the Middle Earth Gods is changing, and Hu Yanxiong, the leader of the Hero Gang, can only convey the news to Long Qingyun through the Shanggang Cuibaozhai.

Communication tools such as voice transmission stone are convenient to use within a short distance. For example, within a country, the energy field of the received signal is the same and the signal is clear.

If there is information interference between different countries, it will cause the vigilance of the intelligence departments between countries, so the communication stone communication between countries is not very safe and not safe.

The sound transmission stone has its advantages and disadvantages. It is not very popular to promote it. On the one hand, it is expensive, and on the other hand, it has potential risks for users.

Ordinary people cannot afford it at all, and they may not be able to bear the risks involved in the use process.

Therefore, people who use the sound transmission stone are either rich or noble, such as Zhan Qianshu, the helm leader of the Xitu Hezhou branch of Cuibaozhai, Tuoba Xi, the princess of Xiqiang, and Mo Zhixuan, the daughter of the director of the Nanyongtian Palace.

Although Hu Yanxiong, the leader of the Hero Gang, possesses a voice transmission stone, he rarely uses it. On the surface, the Hero Gang is a big boss of a force, and to be honest, he is the leader of the Green Forest thief.

As the leader of the gang, Hu Yanxiong was naturally regarded as a thorn in his eyes by the courts of Donghan, Nanyong and Western Qiang. He wanted to kill him quickly. If Hu Yanxiong easily used the sound transmission stone, wouldn't he have exposed his whereabouts?

Therefore, as a military advisor of the Hero Gang, Long Qingyun is not equipped with a voice transmission stone. This thing is convenient, but it is never safe enough and it is easy to expose his whereabouts.

Long Qingyun sighed at the exquisite sound transmission stone in his hand. After a brief sigh, a smile appeared on his face and thought to himself: "This thing is of great benefit to the relationship between men and women in love and commercial activities. As a military advisor of the Heroes, I should use it less."

Thinking of this, Long Qingyun put the voice transmission stone into the space ring and walked forward in a stairs.

Soon, Long Qingyun returned to the Iron Sword Gate.

Suddenly, there were endless shouts and shouts, and the Iron Sword Sect was resounding. Many disciples were stepping up their martial arts. One and two were ready to try, and they were all ready to prepare for the qualifying competition for the sect disciples two days later.

A loud voice sounded: "The day after tomorrow, it will be the qualifying competition for the disciples of the sect. Everyone should practice hard. The disciples who will participate in the competition this year will have ten places. The official selection will begin tomorrow. All disciples under the age of 25 can participate in the selection."

The person who spoke was a middle-aged man in a grey robe, with a tall nose and wide face, a tall face, a tall face, bright eyes, and possessed the combat power of a ninth-rank martial emperor. This person was Sikong Wei, the seventh elder of the Iron Sword Sect.

Seeing Long Qingyun coming back from outside, Sikong Wei glared at Long Qingyun fiercely and said coldly: "Long Qingyun, you don't have to participate in the training. The Great Elder asked you to go to his study."

Although Sikong Wei was dissatisfied with this young man who had just joined the Iron Sword Sect not long ago, he didn't practice martial arts at home on the eve of the qualifying match of the sect, he actually ran out to hang out. Although Sikong Wei was very dissatisfied, Long Qingyun was a disciple of the great elder Sikong Yi after all, so he couldn't say anything. He just showed disgust and contempt between his words and expressions.

"Tu tu tu!" Long Qingyun stood at the entrance of the study.

"Come in!" A middle-aged man's voice came from inside.

This is a simple and elegant study room. On the purple sandalwood desk, the four treasures of the study are all available. There are manuscripts and calligraphy on the table, there are a few wolf hairs in the pen holder, and a figure painting is hung on the wall. A middle-aged scholar standing with a sword is vividly displayed on the painting. This person is elegant and handsome, and is actually a Middle-earth person.

The sunlight penetrates the window lattice, sprinkling light spots on the floor.

A middle-aged man with a tall gray robe paced back and forth. He was tall and deep, about forties, with a clear and vigorous appearance, and his eyebrows were so heroic that he was in his every move. There was a scent of a tiger and a dragon.

This person is Sikongyi, the great elder of the Iron Sword Sect, and his martial arts level is ranked behind the sect leader Sikong Yu.

The great elder of a sect is the second-grade martial arts master. The Iron Sword Sect can rank among the four major sects in Xitu Hezhou and has been well-known for hundreds of years in the martial arts world. It is a veritable strength.

Although the Dashi Empire established an empire and dominated the Western Hezhou, its royal sword palace is the Dashi Sword Mansion. So far, Linghu Xu, the current owner of the Dashi Sword Mansion, is the number one master of the Dashi Sword Mansion, and his martial arts cultivation is only at the level of a half-step martial master.

That is to say, Linghu Xu, the number one master of the Dashi Sword Mansion of the Royal Sword Mansion, has a combat power that is not as good as Sikong Yi, the great elder of the Iron Sword Sect.

As for the other three major sects, the Sharia Sect, the Joy Tower, and the Meihua Immortal Palace, their overall strength is still above the Iron Sword Sect.

This is the gap between the Great Food Sword Mansion and the four major sects, and the Iron Sword Gate is ranked last among the four major sects.

"Master, are you looking for me?" Long Qingyun bowed and said with a humble manner.

"Qingyun, I heard that you participated in the underground boxing competition today, have you gained something?" Sikong Yi said with a warm face and smiled slightly.

Sikong Yi is extremely favored by Long Qingyun. Although Long Qingyun has only been in the Iron Sword Sect for two months, his martial arts talent is extremely amazing.

The Iron Sword Sect has always been at the bottom among the four major sects, and has always ranked fourth in the sect disciple ranking competition every five years. This situation has been the case in recent years.

In this year's sect disciple ranking competition, if nothing unexpected happens, the Iron Sword Sect will be ranked last among the four major sects.

Ren Kuang, a genius disciple of the Motian Sect, Gongsun Jie, the youngest master of Xiyuelou, and Nangong Yanran, one of the youngest "Seven Immortals of Meihua" in Meihua Immortal Palace. These three are all leading figures in the younger generation of Xitu Hezhou.

In this qualifying competition for disciples of the sect, these three people have a high voice. Although the younger disciples of the Iron Sword Sect are good, they are still slightly inferior to these three people.

However, this is just the previous opinion.

The arrival of Long Qingyun made it possible for the Iron Sword Sect to attack the Third A.

Long Qingyun looked embarrassed and said a little embarrassed:

"Master, my disciple participated in the competition at the underground fist shop and defeated Linghu Xiao from the Dashi Sword Mansion, but was defeated by Nangong Yanran from the Meihua Immortal Palace."

Sikong Yi was slightly stunned: "Oh? You were defeated by Nangong Yanran of Meihua Immortal Palace? Are you pretending to be defeated?"

Long Qingyun didn't comment, but just smiled faintly.

"You ghost elf, Master doesn't know what you are thinking!" Sikongyi looked relaxed and stared at Long Qingyun's handsome face, his eyes full of love.

Sikong Yi took a step forward and came to the wall where the painting was hung. He pointed to the painting on the wall, and said with a solemn expression:

"Do you know who the character in this painting is?"
