While some people are seriously discussing and thinking about the questions raised by a play, some people are doing all kinds of work in some part of the field.

And some of these people are testing a source device called 'Yanxin', which is also a communication tool that has appeared many times in "Three Hundred Years of Wanyuan" before.

In that play, the communication tool of Yanxin seems to be very mature, and it can easily have one-on-one voice chats with others, which has attracted a lot of attention.

But in reality, voice chat is not so easy......

The master of the source instrument who tested the word letter in this uninhabited place knew that the current word letter could only send and receive text messages, and it was still very difficult to transmit voice messages.

After all, to transmit voice messages, more source gas needs to be consumed!

At present, the 'ethereal spirit medium' deployed in the wild by the Wanyuan Continent is still very limited, and the consumption of remote transmission of voice information is still very large.

At present, if you want to reduce this consumption, you can only find a way to increase the effect of "Concentric Knot", or find a way to reduce the consumption of "Feihong Secret Order".

In that scene, the sound heard by the theater friends was actually just that the filming team used a special way to insert the sound into the picture.

One by one, the source gas test team is in the field with a few Yanxin, and they are constantly doing various tests and recording various data at the same time.

Some of the masters are also collecting their data around the area, and they are thinking about how they can improve the exercises associated with this test.

The role of "Concentric Knot" should be improved.

"Fei Hong Secret Order" should continue to reduce consumption.

The Ethereal Tactics also needs to find a way to make some improvements to make its staying power more powerful, so that after getting more standby time, the person who provides the Ethereal Clone will not have to replenish the clone repeatedly.

The job of the source masters is to find ways to improve the message so that it can more accurately locate the target it wants to contact, and then accurately deliver the message.

After months of repeated testing, they know that it is now easier to locate and accurately deliver text messages, but it is still easy to string together with other people's voices when sending voice messages, so they are working on solving this problem.

According to the experience of the source masters, this matter will take about one to three months to complete, but this world is not long.

......

In the city, more and more clerks from different organizations began to practice the exercises recommended in the golden book list released by Su Yan, many of these clerks were the second generation of clerks, and they were arranged by their parents to practice the "Text Library" at a very young age, because the leaders of the organization signed a contract with their parents that as long as their children practiced the "Text Library", they would leave a job for their children.

Therefore, for these people, if others want to cultivate the exercises in Su Yan's "Six Mediums and Everything" exercise list, they still need to cultivate the "Word Library" for several years, but they can use a few months to learn the other exercises in this book list and then directly create the Void Spirit Medium.

After this kind of medium doppelganger is created, they can rent it to those masters for testing and they can directly get a lot of money, and after the test is successful, they can continue to rely on this ethereal medium to earn income, and they are simply happy at this time.

In the past, they only felt that cultivating this "Word Library" was not good for their own combat effectiveness, but now that they have one more opportunity to make a lot of money lying down, they may be able to use resources to pile up their combat power in the future.

In more places, there are already literary institutes that are making efforts to recommend the main exercise of "Word Library", and they also tell the students and parents in the academy that after practicing this exercise, they can also get a reduction quota, so that their children's future life safety can be more guaranteed.

Using this method to recommend it has also attracted many people to let their children practice this exercise, for them, it doesn't make much sense to be strong in this era, and not going to the battlefield is the most important thing.

Moreover, the cultivation of the "Text Library" is faster to build the foundation, and the cultivation will be easier in the future, the two children of the family with copper and other resources, one cultivates the "Text Library", and the other cultivates the traditional major exercises, maybe the former cultivates to the tenth layer of open source, and the latter is still a cultivator of the seventh or eighth layer of open source.

At that time, even if the combat power of the cultivators of the text library is not comparable to that of cultivators of the same level, how can the combat power be stronger than that of their peers who are two or three levels inferior?

Therefore, it is actually quite cost-effective to let your own children practice this exercise.

......

While many people are working hard to improve the completion of the "Six Media and Everything" system, and when many people are working hard to increase the number of readings on Su Yan's golden book list, Su Yan is listing all the exercises he has read before.

Since becoming an introducer, he has been carefully reading the exercise books for nearly a year, and has recorded nearly a thousand exercise books in his notebook at this time.

Theoretically, with so many kinds of exercises, if he draws five exercises from them to make a book list, he can make up many different book lists.

He used the various calculation exercises collected in Huang Xiaobing's book list "Wushuang Arithmetic" to calculate, and found that if he didn't consider the quality, he could make up a trillion book list.

However, if you want to consider quality, just do the calculation of permutations and combinations, and obviously you will not be able to achieve the purpose you want.

So, after listing the names and functions of these exercises, he began to seriously review the exercises he had read before.

On the other side, Thorn Sheng saw that Su Yan was reviewing, and he didn't bother out loud, but carefully read the exercise book in his hand.

Half a month has passed, and Su Yan feels that he still hasn't found a suitable book list combination through review, and he always feels as if he is still a little short of satisfying himself no matter how much he makes up.

So he tried to calm himself down, and when he couldn't calm down, he would go home to accompany Huang Xiaobing and his daughter, or take them out to play, and occasionally go out of the city for a walk.

But more often than not, he was still reading the exercise book in the Ten Thousand Scrolls Scripture Pavilion, and he hadn't read the new exercises for half a month before, and he didn't want his reading habit to be broken.

Thinking that it was already March 15, Su Yan went to buy a batch of book lists after reading the exercises for two days, and then bought some exercises to take home to study with Huang Xiaobing.

One day, while reading the exercises, he suddenly had a flash of inspiration and thought that he should go and see how different organizations worked, and maybe he could think of some combinations of exercises that suited them and write a list of exercises with relatively high quality.

So when he went to Baiyi Pavilion in the afternoon the next day, he looked for the pavilion master of Baiyi Pavilion in Qingcheng by the way, and asked him if he could let him go to different organizations and production departments to have a look.

The pavilion master said that he could only let him go to some official organizations, and as for the unofficial organizations, he had no way to arrange them, so he could only let Su Yan ask the leaders of others by himself.

So Su Yan begged him to help him arrange it for him, so that he could go to the official organization to have a look, and said that it was very important for him to write a book list.

The Qingcheng Pavilion Lord's heart moved, and he thought, "If you can help him write a golden book list this time, his reputation will be even closer, and our Qingcheng may be able to increase his prestige even more." ’

So, he asked people to arrange it for Su Yan.

After Su Yan left, he remembered that the population flow in Qingcheng had indeed been more frequent than before in the past few months, and it was still very useful to use golden books to advertise.

You must know that Su Yan is here, and when people are arranged to copy the book list in the thousands of cities outside, they will write the word Qingcheng on the book list, and there are many people who know this city, so naturally some people will want to come and see it.

Even if it only attracts one thousandth, it can bring a lot of popularity and talent to Qingcheng.

Under the leadership of a Baiyi Pavilion media staff who often deals with other official organizations, Su Yan visited the working environment and working mode of more than 20 official organizations in ten days, and thought more about the exercises to be selected for the new book list.

Next, he thinks he needs a little time to think about it.

After another two days, Su Yan felt that he was ready, and he planned to release a book list for the workers of the war preparation station, which should contain some source art exercises that would speed up their work efficiency.

Su Yan looked at his exercise book, and selected more than twenty different source techniques from it, thinking about which exercises were the most suitable.

At first, he planned to completely recommend the new exercises that were less popular, but then he felt that only recommending the new exercises did not seem to be the best choice.

Although the new exercises are fully recommended, if the workers in the war readiness station want to learn this set of exercises, they will buy all the exercises in the book list, and they can earn more money and Baiyi points.

However, this kind of recommendation method has undoubtedly increased the difficulty of other people's cultivation, and on the whole, the increase in work efficiency brought by this set of exercises composed entirely of new exercises does not seem to be the highest.

After thinking about it for a long time, Su Yan finally planned to recommend two source techniques that had been practiced by many workers, and then recommend three new exercises that greatly improved their work efficiency.

In this way, each worker can earn a lot of money and Baiyi points by only taking his book list to buy three new exercises, and the workers don't have to go to the trouble of practicing five new exercises.

Moreover, even those two old exercises don't seem to have been practiced by every worker, so the amount earned by this combination will not necessarily decrease, on the contrary, others will think that it is not difficult to improve the cultivation efficiency by only cultivating the three source techniques, and then take his book list to buy the exercises.

After thinking about it, Su Yan took out a few pieces of paper and began to study how to write a recommendation for a new book list, and Huang Xiaobing sat quietly next to him like this, occasionally looking at a book, occasionally looking at a child, and occasionally looking at him.

In this rhythm, the time suddenly came to April 6th, and Su Yan finally completely finalized the recommendations for all the exercises and completed the writing of this new book list.

And his book list has been prepared for too long, and Huang Xiaobing also wrote two book lists on a whim, and she estimates that these two book lists can only reach the level of green book lists.

After Su Yan re-transcribed the content of the new book list, he asked Huang Xiaobing to help him check and refer to it, and after both of them felt that there was no problem, Su Yan took his book list and Huang Xiaobing's two book lists to the reading group on the fifth floor of Baiyi Pavilion in Qingcheng, and after submitting the book list, he went straight home.

Next, you just need to wait for the examiner to complete the review and then confirm the message.

After returning home, Su Yan asked Huang Xiaobing: "Bing'er, you say, can my book list be set as a golden book list?"
