I haven't heard this tone for a long time. In Shengong City, Renault said everything. He was straightforward whenever he had anything to do. Renault didn't like the officials of Dachu, and those people couldn't get close to Renault at all.

The words "Thunderstorm" are not exaggerating, but are acknowledging the identity of Renault's secret master.

The recognition among secret masters does not mean that you can just write the two simplified Chinese characters Xuanmen. It is said that this is the secret master's ungod secret, which in Renault's opinion is nonsense.

Bai Jing is in the studio, with the word "Xuanmen" hanging. As long as you are not a fool, you won't be able to learn it in a long time. The only difference is whether the stroke order will be wrong.

It is very easy for a secret master to let his children impersonate secret masters and teach them how to write the word "the two" words.

The identity of a secret master is determined by the secret techniques they make. Without secret techniques, even if you are a secret master apprentice, even if your teacher thinks you are already a secret master, you will not be recognized.

The identity of Renault's Secret Master was not entirely decided by Bai Jing and Fire Masters. Before he met them, the people around him had already admitted that he was a Secret Master.

The recognition of the two seniors can only be considered a name-reform at most, and it does not have a great impact on Renault's identity.

Mining conveyor belts, preheating furnaces, ore smelting refined iron, casting arrows, these secret techniques made Renault recognized in the southwest Dingjun City.

Wired telephones, wireless intercoms, hot air balloons, airships, fine iron city, and fine iron ships are the guarantee of Renault's status. As for water heaters and toilets, they can only be regarded as small things that Renault secret masters enjoy for their personal enjoyment. Although these things are very magical in the eyes of the nobles of Da Chu, everyone is rushing to buy them first, and they can only be regarded as a stable position as a secret master and are of little use.

The first sentence of the Thunderstorm meeting was that he recognized Renault's identity as a secret master. He was to show his position, with a hint of compliment and a hint of appreciation.

Thunderstorm is an old secret master in Austria. Originally, he didn't need to care whether he was recognized by Renault. Billions of people in Austria admitted it. It doesn't matter whether he was recognized by the enemy.

But this time when he came to Shengong City, he needed to be recognized by Renault. Without the recognition of the secret master, the next thing could not be implemented.

"What does Mr. Lei think of the Secret Master?" Sure enough, Renault did not recognize his identity, and the next step was the test of the Secret Master.

It's funny to think about it. Thunderstorm is one of the oldest secret masters in Austria. He is a senior secret master. He has tried many people, including real secret masters, and more of them are fakes.

Unexpectedly, at this age, he was about to be buried, but he was tested by a young secret master who seemed to be less than 30 years old.

"As a secret master, explore, discover, and seek knowledge." Thunderstorm said calmly.

Renault looked at Thunderstorm in surprise. If he remembered correctly, this is a very famous science channel column on Earth. It not only has TV programs, but also has a large series of books with a lot of content and all-encompassing content. Renault has only read a little.

Interestingly, this old man could have traveled through time, right?

This thought just flashed by, and it was obvious that this was impossible. Look at what I have done in the past few years and then look at the age of Thunderstorm. If he were the same as himself, the Ao Ren would not be so weak.

Renault has his own plan. If it weren't for the Ao people's invasion, he would definitely be able to improve the natural sciences of Dachu in the next thirty years and advance the scientific system for hundreds of years.

There is no way, Renault has only one person, and the major he is studying is electronics. If it is chemical or mechanical, it can improve this plan a lot.

Science has a context. No matter how strong a person's talents are, they can improve only in a limited way. If it is a team, it is normal to upgrade technology for a thousand years.

For example, if a mechanical expert comes over, he cannot fully improve the machinery in a short time. He needs to manually manufacture the first machine tool, and then use the first machine tool to make the second with higher accuracy. This will be repeated until the accuracy of the machine tool reaches the limit he can reach.

In addition, corresponding supporting products are needed. Modern manufacturing is a system, and no one can exist alone.

This is how Renault did it, starting with smelting. Metal materials are the starting point. Without materials, nothing can be played with. His brains of electronics knowledge, but until now, something as simple as radio still cannot be put into practical use.

This is not because Renault was lazy when he was in school. He really knows it, but if you have something in your mind, but without the support of the corresponding system, you can't do it at all.

"What has Mr. Lei accomplished?" After a moment, Renault continued to ask. He would not admit his identity as Leistor because of those six words. This is the secret master's routine. Renault did not want to break the rules.

"I am ashamed and wasted my years, and I don't have many secret techniques. When I was young, I was full of enthusiasm for the sea. When I was fine, I made paddles to speed up the ship. I made skateboards for fun and made tortoise shell ships. I wanted to explore the underwater world, but I was ignorant." Leistor sighed lightly, and the three secret techniques he casually said, the paddles and tortoise shell ships were all the prides in the hearts of Austrians.

In particular, the tortoise shell ship can not only sail on the sea surface, but also sneak on the seabed for an hour. It is known as one of the eight secret techniques in the history of Austria.

"Tortoise shell ship? The two ships are interlocking and are not water-permeable. The water tank is filled with water and is suspended underwater?" Renault asked in surprise. This thing is quite historical and is one of the earliest submarines.

Due to the manufacturing process problems, the tortoise shell ship is too dangerous. It is indeed able to submarine and the probability of damage is as high as 50%.

Renault knew this kind of thing, but never wanted to make it. It was a life-threatening thing. And even if he could submarine, without the corresponding weapons, he was just a big toy.

Renault said casually, and the thunderstorm's eyes were about to pop out. This is the secret of the tortoise shell ship. Although it was a secret technique in the early years, until now, there are not many countries in Austria that have mastered the manufacturing of tortoise shell ships. The total number of tortoise shell ships is only a few hundred.

As Renault thought, the tortoise shell ship is purely a big toy, with poor practicality and great danger. The powerful and powerful people are afraid of death and dare not use it. Those who are not afraid of death do not know what to use it for.

A tortoise shell ship, even the crew, can only carry dozens of people. Even if it can sneak through blockade waters and steal into the enemy territory, what can dozens of people do?

"You...how do you know?" The shock in his heart was imagined by Renault.

"It's nothing, Mr. Lei has other secret techniques passed down to the world?" Renault said calmly. Although he was not called Master Lei, the last secret technique passed down to the world was actually acknowledging the secret of Thunderstorm.

Even if Renault is made, it will not be possible to complete things like a tortoise shell ship in just a few years. In theory, there is no problem, but there are more problems that submersibles need to consider, and it is difficult to solve just a seal.

"There are nothing else." Lei Shao shook his head. Of course, his secret techniques were not just these, but also many. It would be better not to mention small things. The things that were originally worthy of his pride when he arrived in Da Chu did not realize that they had already had them, and they were better than his.

"It's nothing more than an iron chain ship and a raft floating on the island, which hurts the sky and the sky." Leistor sighed. There was nothing he could do about it. The former was okay, and it made considerable contributions to getting out of the fog, but the latter seemed to have countless living people, but at the same time, he buried ten times the Ao people in the sea. He didn't think there was anything to be proud of in this secret technique.

That's right, the Ao Ren's plan for raft floating islands was made by thunderstorms. It was originally a last resort for Ao Ren's self-rescue. It's best not to use it.

Unexpectedly, shortly after he left Austria, the natural disasters in Austria continued to deteriorate, and this last resort had to be used in advance. It was this plan that caused the turmoil that might have caused invisible.

Whether it is the Chu people or the Ao people, they are essentially the same. As long as there is still a glimmer of hope, there will be no crazy chaos.

"There is a hot air balloon, so it's better not to mention this matter." When it comes to hot air balloons, it's the most regrettable thing. This legendary secret technique took him nearly ten years. Before he could be proud of it, he found that there were not only hot air balloons, but also airships and airships in the sky of the Chu people.

In his most proud place, he was completely beaten by others. This is also the most curious thing about Renault. I have heard that Renault's secret master is very young. When I saw people with my own eyes, I realized that he was younger than he thought.

It is said that this Renault secret master was already a secret master a few years ago. At that time, he was only in his early twenties. I have never heard of such a young secret master. At his age, Lei Shao was still trying to become a secret master apprentice recognized by his teacher.

"Master Lei, what do you think the secret master should be?" Leistor actually used a respectful word. Renault's words revealed the secret technique of the tortoise shell ship completely differently about Renault.

Although the secret master is concerned with respect for the elderly, he still speaks through secret techniques. Renault's secret techniques are obviously a little higher than him, which makes Thunderstorm happy and jealous.

Renault is also a surname of Lei. The secret masters of the surname Lei all come from the same ancestor. Even after thousands of years, everyone's skin color has different colors, but the ancestors will still not change.

Lei Shao is a very recognized ancestor. Because Lei Jun's surname is Lei, he thought Lei Jun was useless, but he was willing to take the risk of landing with the First Fleet, which shows how deep he recognized his surname and clan.

Of course, it is worth being happy that the Lei family has a secret master like Renault, but Renault is the secret master of Da Chu, which makes Lei Shao very puzzled.

Renault had never studied the surname Lei. If he studied it carefully, he would find that there seemed to be no surname Lei in Da Chu. Apart from him, he had only taken in children with his surname Lei.

"Discover problems and solve problems." Renault answered casually. Questions and answers similar to chicken soup in the soul, Renault didn't need to go through his brain, he just opened his mouth.

"It's wonderful." Lei Feng said excitedly. The Lei family has produced talents. Renault revealed the meaning of the existence of the Secret Master in one go.

"Master Lei, since that's the case, what problems do you think you have discovered and how should you solve them?"
