Supersonic fighter jets are extremely fast and do not allow the slightest error. If the appearance design is not reasonable, breaking the sound barrier when going at the speed of sound will become a fatal blade, causing the fighter jet to lose balance or even tear the fuselage, resulting in a very horrific air crash.

However, Lynn has full confidence in the research and development of supersonic fighter jets, because he has avoided most of the problems that will be encountered in the design, which is equivalent to directly announcing the correct answer, saving decades of research and improvement time.

This is undoubtedly a bit of a hasty move. If the parliament was not facing a cross-border war, Lynn would not have directly shown the most perfect fluid mechanics structure to Dennis. After all, correcting mistakes is itself a very valuable experience.

Dennis memorized the several design drawings drawn by Lynn firmly in his mind, and Lydia and others were no exception, because the shapes and structures of the aircraft on these drawings looked extremely beautiful and pleasing to the eye, they were simply works of art!

Tim hesitated for a while before speaking with concern, "Chairman Lin, if the speed of the fighter planes continues to increase, will the pilots inside find it unbearable or unable to react quickly in battle?"

"You underestimate the limits of what humans can achieve. As long as we undergo appropriate training, it won't be a big problem to withstand high pressure that is several times the acceleration of gravity." Lynn explained.

Before federal researchers deciphered the genetic modification technology, the pilots of supersonic fighter jets were selected from ordinary people. Since they had no problems, let alone wizards with better physical fitness and quicker reaction abilities!

The only thing that needs to be considered is how the fighter pilot can distinguish between friend and foe while flying at high speed.

On the technological level, radar is usually used to solve the problem, but this is obviously not safe enough because the opponent may have some means of shielding or interfering with the electromagnetic field.

So Lin En plans to add another layer of insurance. Based on the position of each fighter plane, he will build an airspace network that can sense magic power, and use the magic network link of the intelligent brain to achieve real-time information sharing and distinguish between friend and foe.

During the battle, the targets in the air and connected to the magic net are our own people, and the rest are enemies that need to be dealt with.

"In this way, we don't have to worry about the most critical problem of detecting the enemy." Dennis nodded, and then continued to ask, "Then should we engrave a windproof magic circle on the outer shell of the fighter plane as usual to slow down or eliminate the impact of the shock wave..."

"No, there is no need for the wind-proof magic circle. Instead, it will increase the wind resistance of the fighter plane, thereby reducing its speed..." Lin En shook his head.

Although windproof magic is easy to use, its operating principle is to create a cone-shaped, constantly flowing magic barrier in front, thereby achieving the effect of separating the airflow. It is very useful when flying at low speeds, but not at high speeds.

Because the output speed of magic power cannot keep up with the flying speed of the fighter plane, the barrier itself will be torn apart by the continuous high-speed airflow.

Lin En suggested that they could consider coating the outer shell of the fighter with a layer of graphene. Once activated, it would form an electromagnetic shield around the fighter, which would be enough to effectively resist some low-level magic attacks. Most importantly, it would prevent the driver from suffering external mental damage - this is what the fighter pilots fear the most.

After thinking for a while, Lin En took a blueprint, wrote a chemical formula, and handed it to Dennis. "This is the method of making the Eternal Flame. You can try to use it in the development of offensive weapons for fighter planes, but... be careful!"

After being promoted to Legend, chlorine trifluoride was no longer his most important means of attack. It was time to join the wave of industrial production. Only large-scale mass production could truly unleash its power! Dennis took it very seriously. He had heard about the horror of this thing, which could devour almost all known elements as nutrients.

Tim looked at the blueprint in Dennis's hand with great envy. The Eternal Flame was one of the few means that could allow great wizards like them to threaten legends.

When this magic star had not yet completed his promotion, he used it to kill the legendary priest Edelweir! After Lin En gave the chemical formula for making chlorine trifluoride, he did not forget another purpose of coming to the Alchemy Research Institute this time, which was to second several halflings to contact Raphael and others outside the space-time gate.

Dennis didn't care too much about this. With Tim's promise of full support, the assistance of these halflings was dispensable, and it didn't matter if there were more or less.

Lynn left a book on fluid mechanics for Dennis to study on his own, and then called Lydia, Darren and others to tell them the news that the exploration team had discovered a group of halflings outside the space-time gate.

"It is indeed possible." Lin En nodded, then smiled and said, "But does it matter where it comes from? Now foreign lands are almost becoming a forbidden place for living beings..."

Darren and the others naturally had no idea of ​​following the footsteps of their ancestors and returning to foreign lands. The Halfling people had taken root in this continent for hundreds of years, and this was their homeland.

“In short, I need to select a few of you to carry out a dangerous mission - to assist Master Raphael and go to a foreign land to gather intelligence…” Lin En explained the goals of this mission and the possible risks that might be encountered.

He had no intention of forcing or commanding these halflings, but rather followed the principle of voluntariness.

After all, once they arrive in a foreign land, the parliament's control over them will become extremely weak, and even the magic network will not be able to connect there. Raphael cannot take care of everything, and he has to act entirely on his own initiative.

All the halflings hesitated. According to the Magic Star, the world outside the space-time gate was not only very cold and without sunlight, but also filled with a large number of dangerous monsters. If one was not careful, one might die in some corner.

"Let me go!" Darren gritted his teeth and was the first to agree.

"I'm going too, I'm going too!" Lydia agreed enthusiastically.

"No, Lydia, you'd better stay in the Alchemy Research Institute first. The test flight of the new fighter jet still requires suitable personnel." Lin En shook his head. Lydia's personality was not suitable for intelligence work. It would be a bad thing. It would be better for her to stay in the royal capital.

The latest chapter of this novel was first released on 6@9shu#bar. Please go to 69shu#bar to read it!

After Darren and Lydia spoke, the other four halflings soon stood up and expressed their willingness to undertake this dangerous intelligence exploration work.

"Very good, as long as you can complete this task, I will make an exception and allow you to join the magic network and become a wizard!" Lin En promised.

Hearing this, Darren and the others immediately became excited. In the magic kingdom, wizards are the symbols of power, authority and status. Halflings like them who have no magical talent will never be able to become wizards in their entire lives without external help.

Lin En's words undoubtedly represent an opportunity to achieve success overnight.

The halflings who had hesitated because of fear before were annoyed and regretful. Although the foreign land was dangerous, compared with becoming a wizard, the risk was nothing.

"Speaker Lin, when are we leaving?" Darren asked impatiently.

"About a week later." Lin En said afterwards. During this time, they still had to learn how to use some instruments and the common language of the other world...

Raphael had sent a prisoner before, and he should be able to get a lot of information from the other party's mind.

PS: Today I have fewer words, so let me sort out the plot and see how to make it more interesting. Recently, because of the opening of a new map, there will be a little more chapters for foreshadowing. After all, there are a lot of things to explain. I should have finished them in the church chapter before, but there were many people urging me to make progress, so I wrote it faster, and some of the content can only be written now.
